    Chopper resistance with load resistance
    The invention comprises a load resistance chopper resistor having the patent features known from claim 1.
    Chopper resistors serve to convert excess electrical energy into heat, for example, in brake choppers. This reaction is followed by a chopper resistance in that a load resistor or several interconnected load resistors are typically controlled by a control electronic, which supplies power, which control electronics normally does not belong to the chopper resistor circuit. The load resistor thereby exhibits an electrical resistance element, for example a wound or on a carrier wound resistor wire or a resistor grid, on which heat is released to the surroundings due to the electrical current flowing through the resistor. Thus, a heating element can also be regarded as an electrical resistance element.
    In the past, in connection with chopper resistors, the patent applicant has realized an embodiment using tube heating elements as electrical load resistance, which outer coating thus acts as a cooling element of metal, and the heat supply from the resistance wires in the tube heating elements improves delivery to the environment at the same time as opposed to the widespread use of also immediately guarantees that no tension is applied to the outer covering so that a special extra electrically insulating location (in connection with attachment is) is no longer imperative.
    Nevertheless, it is desirable to continue to increase the efficiency of the chopper resistance, both in terms of the possible energy conversion in heat and in terms of manufacturing costs. The object of the invention is thereby to show improved chopper resistance with respect to these aspects. This problem is solved by a chopper resistor characterized by claim 1. Further developmental examples of the invention are contained in the dependent claims.
    The chopper resistor of the invention has at least one load resistor which, in particular through / via a control electronics, controls the current through at least one load resistor. there
    DK 2018 70178 A1 at the load resistance exhibits a resistance element, which is designed at least in section as a metal heat sink, or this is accomplished by the fact that the metal heat sink has a resistance chamber. Further, the metal heat sink has at least one cooling duct which is delimited on a wall portion of the resistance chamber and extends substantially parallel to the resistance chamber and / or cooling ribs which extend substantially parallel to the resistance chamber.
    The control electronics can, but need not, belong to the chopper resistor.
    Essential to the invention is that the load resistors are oriented such that cooling ducts and / or cooling ribs extend relative to the horizontal in an approximately vertical position when the chopper resistor is placed in its regular application position.
    When the load resistors are oriented such that the cooling ducts and / or cooling ribs, when the chopper resistor is placed in its regular application position, relative to the horizontal in an approximately vertical location, the heat output obtained is significantly improved. Presumably this has to do with the evolved dynamics of the heat from the cooling ducts and / or heat sink conveying air, which air rises and is replaced by colder air from below.
    This is advantageous when the resistance chamber is tubular. It should be noted that the term '' tubular '' does not, firstly, constitute a boundary in a circular cross-section in a direction perpendicular to the direction of the pipe so that the cross-sectional geometry is kept free. Further, the term "tubular resistor chamber" in relation to this application also includes embodiments in which a wall of the resistor chamber for the entire length is broken through a constriction or gap.
    The resistor chamber need not be tubular, instead formed, for example, with a groove in which the resistor element or a group of resistor elements, e.g. a heater cartridge or tube heater is placed in the groove or pressed into the groove, thereby forming the heating element.
    DK 2018 70178 A1
    In a further preferred embodiment of a resistance chamber, the walls of the individual wall sections may be composed between which the resistance element or a component group containing the resistance element is thereby fixed.
    In the perpendicular arrangement, it turns out to be advantageous to place the load resistors so that their heat generation and heat dissipation under current influence can vary over the length of the load resistance. In particular, the sections of the load resistor which are at the bottom, i.e. near the place where the air is moved by the heating and thereby being sucked in, can thus provide a stronger heat generation and heat emission by influencing current in the load resistance than in the flow direction of the air further along the overlying sections. of the load resistance.
    In practice, for example, by using heater cartridges or tube heaters, the winding s rise of the resistor heater cartridge or tube heater body may be varied.
    In order to optimize the air dynamics of a chopper resistance, it has been found advantageous for the heat sink on the load resistors to be spaced apart.
    The preferred material for a metal heat sink is aluminum, advantageously anodized aluminum.
    In a preferred further development of the chopper resistance, the chopper resistance has several load resistors which mechanically interact with each other in a module. For example, these may be connected linearly to one another in a series.
    In particular, the mechanical connection to a module can be made through one or more rails, which are at least partially secured to a fastener on the load resistors located on the walls of the cooling duct. On the connection side of the load resistor, the connection of the load resistor may be protruding, whereby these may be a rail with a central U-shaped recess in which the electrical leads are fed.
    DK 2018 70178 A1
    Advantageously, it has also been found that the load resistors are electrically connected to a module such that these are grouped or individually utilized and / or grouped or jointly connected.
    A particular advantage is that when the connections on the load resistors are insulated in relation to the load resistor and are routed outside the load resistor itself.
    It is further preferred when the connections of the load resistors occur from below, where the connection of the load resistors is extended, ie in the opposite direction of the stove effect formed by the air currents. A lower ambient temperature prevails so that the insulation on the connection is less affected, which in turn enables cheaper insulation agents to be used.
    Advantageously, load resistors and / or modules of load resistors are placed inside an outside enclosure with openings, especially inside a grating box.
    It is further preferred when the electrical resistance element is formed as a heating cartridge or a tube heating element, which is placed in the resistance chamber. The great advantage thus obtained is that compressed systems are thus also used, which allow for a significantly better heat transport.
    Thereby, for example, a heating cartridge may be used in which the electrical resistance element is a wrapped heating wire on a support body, for example a ceramic support body, in which there is an insulating material filling, for example a magnesium oxide filling inside the inner space of a tubular metal casing and through the insulating filling, whereby electrical insulation is achieved.
    It is also possible to use such heating cartridges in which the electrical resistance element is a coil of a heating wire wound on the outside of the heating cartridge and extending to the connection side, which is an insulating material filling, for example a magnesium oxide filling inside the inner space of a tubular metal casing and through insulating fabric filling. electrically insulated.
    DK 2018 70178 A1
    In a predominantly advantageous alternative thereto, which is also to be regarded as a separate independent invention, the electrical resistance element may also be a tubular heater, which is passed through the resistance chamber as several heat sinks. The heat sinks may also be shaped differently. This significantly enables control and contact of the chopper resistance and solves possible problems with the seal. Further, an improvement in the temperature resistance of the chopper resistance is obtained.
    Similarly, in relation to the second invention, a chopper resistor exhibits at least one load resistor, which is particularly controlled by a control electronics for controlling the current through at least one load resistor. Thereby, the load resistance exhibits a resistance element having several divisions which are also located in a metal heat sink and are continuous, whereby metal heat sinks have a resistance chamber for accommodating the corresponding sections of the resistance element. This invention can be further developed in the same way as the invention directed to claim 1.
    Thereby, in particular, the resistance of the electrical resistance element of the tube heater in the section of the tube heater, which is inserted inside the resistance chamber of heat sinks, the resistance being higher than the other sections of the tube heater bodies to prevent the heating element from being affected by the section in which no heat sink is affected. a large load on the tube heater.
    Both with the use of heating cartridges, but also with the use of tubular heaters, the resistive elements can be stored in magnesium oxide granules, especially in impregnated and / or densified magnesium oxide granules, which provides particularly good heat dissipation.

    Detailed description of the invention
    FIG. 1 shows an embodiment of a chopper resistor 200. The chopper resistor 200 exhibits three modules 210 with each three adjustable operating positions of the chopper resistor 200 extending in a vertical direction, the electrically coupled load resistors 100 being mutually connected grid box forming an outer housing 220 formed with openings. The modules 210 are electrically connected to a connection terminal 230.
    FIG. 2 shows a single view of a module 210. The three load resistors 100 are formed on their upper side opposite the connection side by rails 211, 212, which with fastening channels 155 on the load resistor 100, fasteners in the form of screws are shown.
    At the bottom of the connection area, the load resistors 100 are connected to a further rail 213 which exhibits in its center region a U-shaped recess 213a, and on both sides of the U-shaped recess 213a are shown wide surfaces 213b, 213c, at
    GB 2018 70178 A1 which also includes a connection to the lower end of the load resistors 100 of the cooling ducts where fasteners 153 are located. In the U-shaped recess 213a, the load resistors 100 of the connecting cable 140 are led to a clamping block 214.
    The load resistor 100 exhibits a resistance element not shown in the figure in the form of a heating cartridge and a heat sink 150 of metal. Thereby, the heat sink 150 of metal in this example exhibits a tubular resistor chamber 151 of circular cross-section and cooling ducts 155 which are defined at wall sections of the resistor chamber 151 and extend substantially parallel to the resistor chamber 151, which is arranged so that the load resistor 100 of the resistor chamber 151 is surrounded. of cooling ducts 155.
    The cooling ducts 155 exhibit an inner wall 156 formed by a wall section of the resistance chamber 151 of the load resistor 100, an outer wall 157 which forms a section of the circumferential surface of the load resistor 100 and has support walls 158, 159.
    What is particularly evident in the cross-sectional preparation of FIG. 3, the extension 1, the carrier walls 158, 159 exhibit cooling channels 155 between which adjacent ends 158a, 159a and their distal ends 158b, 159b constitute at least 2.5 times the path of the circumferential geometry of the cross-section of the resistance chamber 151 and thus also the largest cross-section d of the resistance chamber 151.
    Referring to FIG. 2, that, at a pair of the neighboring walls 158, 159 of the cooling duct 155, the adjacent ends of the neighboring walls 158, 159 extend the cooling duct 155a at a small distance relative to each other than the distal ends 158b, 159b of the neighboring walls, whereby the distance between at least two neighboring walls 158, 159 form a cooling channel 155 from its adjacent end 158a, 159a to the distal end 159a, 159b, which proceeds even strictly monotonously uniformly rising.
    The cooling duct 155 of the carrier walls 158, 159 extends in the radial direction from the resistance chamber 151 and extends and surrounds the resistance chamber 151 such that the resistance chamber 151 and the supporting walls 158, 159 form the cooling duct 155, which contains the heat sink 150 of metal and generally has a star-shaped cross section.
    DK 2018 70178 A1
    It is further noted that the ratio of the extension 1 of the carrier walls 158, 159 to the cooling duct 155 to its thickness d is clearly greater than 20. This is clearly seen in the cross-sectional production through the heat sink 150 of FIG. Third
    FIG. 4 shows another embodiment of a chopper resistor 1200. The chopper resistor 1200 exhibits three modules 1210 with each three in the normal operating position of the chopper resistor 1200 extending in a vertical direction to form the load resistors 1100, which load resistors are arranged in a grid box, forming an outer housing 1220 with openings. The module 1210 is electrically connected to a connection box 1230.
    FIG. 5 shows a single display of a module 1210. The three load resistors 1100 are connected on their upper side opposite the connection side with rails 1211, 1212, at the distal end 1152b the cooling rib 1152 the load resistors 1100 are fasteners 1153 in the form of screws.
    In the lower connection area, the load resistors 1100 are connected to a further rail 1213, which in its middle region has a U-shaped recess 1213a, and on both sides of the U-shaped recess 1213a there are wide faces 1213b, 1213c over which a connection is also found. To the distal end 1152b of the heat sink 1152 of the load resistor 1100, attachment means 1153 are provided. In the non-shaped recess 1213a, the connecting cable 1140 to the load resistors 1100 is routed to a terminal block 1214.
    FIG. 6a shows a load resistor 1100 for the chopper resistor 1200 with a resistor element 1111, which in this embodiment is based within a partially open view of a heater cartridge 1110 and formed with a metal heat sink 1150 which in this embodiment exhibits a tubular resistor chamber 1151 with cooling ribs 1152, whereby in the manufacture of FIG. 6a for better visibility, both component groups in an explosion view are shown separately from one another. In the assembled state as shown in FIG. 6a and in the partially opened preparation of FIG. 6e, it is shown that the heat cartridge 1110 is pushed into the resistance chamber 1151.
    DK 2018 70178 A1
    It will be apparent from Figures 6a to 6c that the resistor element 1111 is a wrapped heating wire around a support member 1112 located within the tubular metal housing 1113 and through electrically insulating material 1114, for example MgO powder, which may be compressed as shown in the figures for to create an overview and to obtain isolation of the tubular metal enclosure 1113. Connection of the resistor element 1111 is effected by connecting wires 1115 projecting from the metal enclosure 1113 of the heating cartridge 1110.
    An alternative internal structure of the heating cartridge 1110 can be seen in FIG. 6d. There is the resistance element 1111 'a twisted heating wire which extends into the bore 1116 of an insulating body 1117 to a non-shown pivot point and back again. The insulating body 1117 is located within the tubular metal housing 1113 ', a residual gap between the insulating body 1117 and the tubular metal housing 1113' and the volume remaining in the insulating body 1117 1116 is again filled with electrically insulating material 1114 ', for example magnesium oxide powder which can be compressed is shown in the figure as white to create an overview.
    The structure of the heat sink 1150 is particularly suitable under additional conditions that it is perpendicular to the extension direction, respectively, to the longitudinal axis of the heat sink 1150 resistance chamber 1151 of the sectional cross-sectional view of FIG. 7a as well as the associated retail manufacture of Figures 7b to 7d. From this example of a cylindrical shaped resistor chamber 1151 in which is located a heating cartridge 1110, more precisely indicated on the outside of the wall of the resistor chamber 1151, there are projecting longitudinally extending radially, i.e. in the direction of the illustrated cross-section, imaginary connecting line between the center axis of the resistor chamber 1151 to the wall of the resistance chamber 1151, cooling ribs 1152, which essentially lead to a star-shaped cross-section.
    It should be noted that this definition of the term radial can be readily transferred to obvious possible alternatives of the cylindrical divergent geometry of the resistance chamber 1151, in which it is not circular, instead having, for example, a square cross-section. Thus, the cooling ribs 1152 are not all perpendicular to the wall of such a resistance chamber.
    DK 2018 70178 A1
    As can be seen immediately from FIG. 7a, the extent 1 of the heat sink 1152 in the radial direction thus defined is more than 2.5 times the cross-section of the resistance chamber d. In comparison with known load resistors in the prior art, the heat sink 1152 is thus produced through many larger surfaces on which heat can be delivered to the ambient air. Likewise, the ratio in the radius of the heat sink 1152 to 1 of the thickness D defined through the greatest distance of the largest side surface of the heat sink 1152 is greater than 20.
    The individual cooling ribs 1152 exhibit adjacent end 1152a, respectively, which rests against the wall of the resistance chamber 1151 and the distal end 1152b, which is the opposite end of the adjacent 1152a. Depending on the radial location of the cooling ribs 1152, the distance between the neighboring cooling ribs 1152 grows from the adjacent end 1152a to the distal end 1152b, which is highly visible in FIG. 7b, which causes the inflow of ambient air to be relatively less heated in the middle region between the two cooling ribs 1152 before the ambient air reaches near the wall of the resistor chamber 1151.
    As the sectional magnification of FIG. 7c and 7d clearly show that the distal end 1152b of the heat sink 1152 and between each other pair of adjacent ends 1152a of adjacent heat sink 1152 are devised fasteners 1153 and 1154, respectively, which in this example can be used for engaging pins or screws.
    The fastening means 1153 are formed by the distal end 1152b of the cooling rib 1152 forming a circular section so that in this section a kind of pipe with a through opening in the pipe wall is formed. This method also allows the braking resistor to be pushed onto a corresponding holding bar to realize the attachment; Fortunately, depending on the application, aerial cans can also be placed here to deflect the air flow in a desirable manner.
    The fastener 1154 is formed by the adjacent end of two neighboring cooling ribs 1152 facing each other being formed with nose-shaped projections 1152c, 1152d such that the distance between the two neighboring cooling ribs 1152 at this location locally towards the distal end 1152b of the cooling rib 1152b is narrowed so that a mechanical fixation is obtained by the nose-shaped projections
    DK 2018 70178 A1 π
    1152c, 1152d allow a defined fastener 1154 to be pushed in and act as a retaining pin.
    FIG. 8 shows a third embodiment of a chopper resistor 2200. The chopper resistor 2200 exhibits three modules 2210 with each three in the regular operating situation of the chopper resistor 2200 extending in vertical direction reciprocally electrically coupled load resistors 2100 located in a grid box formed as outer houses 2220 with openings. The module 2210 is electrically connected with a connection box 2230.
    FIG. 9 shows a single manufacture of a module 2210. The three load resistors 2100 are on their upper side opposite the terminal end, connected to the rails 2211, 2212, on which at the distal end 2152b of the cooling rib 2152 of the load resistor 1100 are fasteners 2153, which is screwed in.
    In the lower connection area, the load resistors 2100 are connected to a further rail 2213, which in its middle region has a U-shaped recess 1213a and on both sides of the U-shaped recess 2213a there are wide edge faces 2213b, 2213c, over which a connection to at opposite end 2152b is the cooling ribs 2152 of the load resistors 2152, where fasteners 2153. are provided. In the U-shaped recess 2213a, the connecting cable 2140 of the load resistors 2100 is routed to a terminal block 2214.
    By simultaneously looking at FIG. 9 and 10, the structure of the load resistor 2100 is clearly seen. 10, which is a perpendicular. Parallel to the long side face of the resistance chamber 2151, the heat sink 2152. extends on the short side of the square, fasteners 2153, 2153 are indicated. In the interior of the resistor chamber 2151, resistive wires 2111 are wrap an electrically insulated material 2114, for example embedded in magnesium oxide powder.
    The FIG. 11 and FIG. 12 shows alternative load resistance module 500, 1500 for chopper resistors 200 according to FIG. 1 and 1200 respectively in FIG. 4, shows the peculiarity that the resistor element used does not, as previously stated, where the resistor element is a heating cartridge which is also accommodated in the resistor chamber of the heat sink,
    Instead, the resistor element is a tube heater 510, 1510, which in this example is also located through two heat sinks 550, 560 and 1550, 1560, respectively. Coolers 550, 560 are thus analogous to heat sinks 150 in their structure and heat sinks 1550, 1560 is analogous to heat sink 1150. In the region 570, 1570, the resistance elements of the tube heater 510, 1510 are modified such that less heat energy is generated relative to an unheated area of the tube heater.
