    1348868 Air heaters J EBERSPACHER 26 July 1972 [6 Aug 1971] 35024/72 Heading F4S In a liquid-fired air heater, particularly for use in mobile units such as motor vehicles or ships, a unitary pressure casting or injection moulding 28 which is surrounded by an outer synthetic resin easing 80, defines a combustion chamber 30, a laterally extending precombustion chamber 32, a fuel-inlet connection (34, Fig. 3) opening at an angle into the precombustion chamber 32, a heat exchanger 36 which together with its internal and external finned or ribbed surfaces 38, 40 forms an axial extension of the combustion chamber 30, and a lateral exhaust gas outlet 42. A single motor 12 drives both a fresh air blower 16 and a combustion air impeller 20, the combustion air entering through an inlet 48 being guided into the combustion chamber 30 through an annular nozzle 54 defined between an insert plate 46 having attached baffles 64 and a sheet metal cap 50 carried by and rotating with the impeller 20. Air to be heated entering through inlet connection 82 passes over the external finned surface of the exchanger 36 and leaves as heated air through an outlet connection 84. Combustion gases leaving the combustion chamber, which in part is defined by a funnel-shaped member 68, flow through an open ended perforated flame tube 72 and over the internally finned surface of the heat exchanger to finally leave through the exhaust outlet 42. The air heater can be provided with an over-heat cut-out. The motor 12 and impellers 16, 20 form a unit which is held in position by a supporting element 22 rigidly secured to an end flange of the pressure casting 28 by a number of bolts 24.

    (54) HEATER FOR VEHICLE The aim of the invention is to increase the compactness and efficiency of the heater by reducing the coking of fuel and improving heat transfer while protecting the parts of the heater subjected to temperature effects. This is achieved due to the fact that the prechamber is located radially relative to the combustion chamber, the glow plug is installed in this prechamber, the heat exchanger is made with external and internal longitudinal fins, respectively aligned with the aforementioned annular longitudinal channel and cavity for passage of the combustion products, the exhaust pipe is located The heat exchanger is perpendicular, and the heat-resistant lining is placed inside the combustion chamber. In addition, the lining is made of composite elements in the form of liners. The combustion chamber, the prechamber and the nozzle for the supply of fuel are made in one piece. Such an embodiment of the heater makes it possible to withstand the optimum conditions for burning the fuel, thereby improving the efficiency of the heater, which also becomes more compact due to the implementation of a number of its parts in one piece. At the same time, it is possible to prevent overheating of the walls of the combustion chamber in this heater. FIG. 1 shows a heater, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1. The heater includes a housing 1 in which a heat exchanger 2 is located. It is made in one piece with the combustion chamber 3, pre-chamber 4, nozzle 5 for fuel supply and exhaust nozzle 6. The chamber 4 is located laterally relative to the combustion chamber 3, the nozzle 5 for inlet The fuel is inclined to the pre-chamber, and the exhaust pipe 6 is perpendicular to the heat exchanger 2. The latter has internal longitudinal fins 7 and external longitudinal fins 8. These fins face the longitudinal channel a for the passage of air. In addition, the channel is formed by the walls of the heat exchanger and the housing, relative to which the heat exchanger is installed with a gap. In front of the combustion chamber 3, there are mounted on | pp elements 9 and 10, which direct the air entering the combustion chamber. These guiding elements can be rigidly connected to the casing I, which also has an inlet 12. The casing 11 is connected to the heat exchanger 2 by means of the ridges 13. Inside the casing 11 there is an electric motor 14, on whose axes the wheel 15 of the centrifugal fan is mounted, supplying air to the a heat exchanger, and a wheel 16 of a centrifugal fan supplying air to the combustion chamber. An electric motor 14 is installed in the housing 11 taK, 4TO its longitudinal axis coincides with the longitudinal axis of the heat exchanger. 725 5 10 15 20 25 30 35 40 45 50 55 60 65 9 4 Fan wheel 16 is located outside casing 17, the front side 18 of which forms an axial restrictive wall of the combustion chamber. An annular nozzle 19 is placed between the element 10 and the holder 17, through which the combustion air enters the combustion chamber 3 and is mixed there with liquid fuel supplied to the pre-chamber 4 via the nozzle 5 for fuel supply. Combustion air enters the inlet 12, flows around the electric motor 14 and turns to element 9, then passes between the latter and the disk 20 carrying the blades of the fan wheel 16 to the outside, and then enters the annular space between the holder 17 and element 10, passage along the air guide plate 21 fixed on it, and again diagonally inwards to the annular nozzle 19. A glow plug 22 is installed in pre-chamber 4, by means of which the mixture of fuel and air is ignited in the combustion chamber. A funnel-shaped member 23 is rigidly connected to the element 10, the element 10, the element 23 and the side 18 of the sleeve 17 serving as liners, which form a heat-resistant lining. A heat pipe 24 is connected to the element 23, having several rows of holes 25 arranged in parallel in the longitudinal direction, the rows of which are displaced relative to each other. The pipe 24 is in communication with the camera 26 burnout. Combustion products from the flame tube get into the burner chamber 26, and from there into the cavity 27, where they come into contact with the fins 7 of the heat exchanger. Combustion products can enter the same cavity from the openings 25 of the flame tube, and from the cavity 27, the combustion products are discharged through the nozzle 6. The inner 7 and outer 8 longitudinal fins of the heat exchanger have different lengths. Thus, the ribs 7 extend from the pipe 6 and continue until the end of the exchanger from the side of the afterburner 26. In turn, the fins 8 of the heat exchanger begin at the location of the prechamber 4 and also continue to the end of the heat exchanger from the side of the afterburner 26. In addition, the height of the outer ribs is the same, and the inner edges are variable with a ratio in height of 1: 2 (see Fig. 2). The body 1, which is made of synthetic material, is flanked on both sides by ball caps 28 connected to it, having connections 29 and 30, respectively, for supplying and discharging air. Seals (not shown) are provided in the connection area of the housing with the covers, and to ensure their centering they are connected by, for example, three screws (not shown).
    To facilitate centering of the housing 1 with respect to the heat exchanger 2, the sides of the latter can be made conical.
    Thus, the heater is compact in design, has an increased efficiency and allows removable mounting on the vehicle by means of supports.
