    Refrigerator condenser and its manufacturing method
    The present invention relates to the field of refrigerators, and more particularly, to a condenser that serves to condense a high temperature and high pressure gas refrigerant compressed by a compressor to a low temperature low pressure gas refrigerant by heat exchange while constituting a cooling cycle.
    In general, a refrigerator is an apparatus used for long-term storage of food freshly, as shown in FIG. 1, and includes a main body 1, a freezer compartment 2 formed in the main body to refrigerate food, and a refrigerating chamber for refrigeration. 3) and a cooling cycle for cooling the freezer compartment 2 and the refrigerating compartment 3.
    The cooling cycle includes a compressor 4 for compressing a low temperature low pressure gas refrigerant into a high temperature and high pressure gas refrigerant as shown in FIG. 2, and a condenser condensing the high temperature gas pressure gas refrigerant into a high temperature and high pressure liquid refrigerant by heat exchange. 5), a capillary tube 6 for converting the high temperature and high pressure liquid refrigerant into a low temperature low pressure liquid refrigerant, and an evaporator 7 for evaporating the low temperature low pressure liquid refrigerant to a low temperature low pressure gas refrigerant to generate cold air. consist of.
    Therefore, when the refrigerated food is filled in the freezer compartment 2 integrated in the main body 1 and the refrigeration chamber 3 is supplied with the refrigerated food in the state of filling the refrigerated food, the compressor receives the control signal of the controller to form a cooling cycle. (4) is driven to compress the low-temperature low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant, the compressed high-temperature high-pressure gas refrigerant is heat-exchanged while passing through the condenser (5) to condense into a high-temperature high-pressure liquid refrigerant, this condensation The high temperature and high pressure liquid refrigerant is continuously converted into a low temperature low pressure liquid refrigerant whose temperature and pressure are rapidly dropped while passing through the capillary tube 6, and then into a low temperature low pressure gas refrigerant while passing through an evaporator 7. Subtracted causes evaporation to produce cold air.
    The low-temperature low-pressure gas refrigerant forms a cycle of returning to the compressor again according to the continuous operation of the compressor (4), wherein the fan (8) installed at the rear of the freezing chamber (2) rotates and cool air is cooled with the freezing chamber (2). Since the food is supplied to the refrigerating chamber 3, the food filled in the freezing chamber 2 is frozen by the supplied cold air and the food filled in the refrigerating chamber 3 is refrigerated.
    The conventional condenser 5 constituting a cooling cycle in the refrigerator as described above is a refrigerant pipe 51 and a wire (wire) in the form of a single body integrally bent as shown in FIG. It consists of a plurality of fins 52 fixed to 51.
    Therefore, the high temperature and high pressure gas refrigerant compressed by the compressor 4 constituting the cooling cycle flows along the refrigerant pipe 51 of the condenser 5, whereby air passes between the refrigerant pipes. Since heat is radiated to the outside in the process of flowing the refrigerant pipe 51 which is integrated into one and bent in a predetermined form, the gas refrigerant of high temperature and high pressure is condensed into a liquid refrigerant while being heat exchanged.
    On the other hand, a plurality of fins 52 in the form of wires are fixed to the coolant pipe 51. When the heat of the gas refrigerant flowing along the coolant pipe 51 is radiated to the outside, the heat dissipation area is widened to increase heat exchange efficiency. This is to further increase.
    The conventional condenser is a step of bending a predetermined length of the refrigerant pipe 51 as shown in Figure 4, and a plurality of wire-shaped fins 52 in contact with the refrigerant pipe 51 is bent in a specific shape. The step and the step of fixing the refrigerant pipe 51 contact portion of each of the fins 52 to the refrigerant pipe by spot welding is made in sequence.
    In more detail, the operator may be provided with a predetermined length of the refrigerant pipe 51 and then bend the refrigerant pipe into a specific shape.
    Then, each of the fins 52 in the form of wires is brought into contact with the refrigerant pipe 51, and then spot welded to each of the refrigerant pipe 51 contact portions of the fins 52 using a spot welding machine. Production of the condenser is completed while 52 is fixed to the refrigerant pipe 51.
    However, in order to fix each fin in the form of wire to the refrigerant pipe during manufacturing, such a condenser has to be spot-welded one by one of the contact portions of the refrigerant pipe and the refrigerant pipe. As well as the problem, of course, a plurality of wire-shaped fins are used to increase the heat dissipation area of the refrigerant flowing along the refrigerant pipe. There was a problem that the heat exchange efficiency of the refrigerant falls.
    The present invention has been made in order to solve the above-mentioned problems, and to reduce the labor cost according to the production to reduce the production cost, and to increase the heat dissipation area by 향상 to improve the heat exchange efficiency of the refrigerant flowing through the refrigerant pipe during use Its purpose is to make it possible.
    According to the aspect of the present invention for achieving the above object, a plurality of refrigerant pipes are formed integrally between the thin plate fin (Fin) and positioned in a specific form, and one end of one of the refrigerant pipe ends The refrigerator condenser is connected to the other end of the other refrigerant pipe and is connected to the other end to form a U-shaped connection pipe which integrates each refrigerant pipe into one refrigerant pipe, while providing the refrigerator condenser. Extruding a plurality of refrigerant pipes integrally with each other; bending each specific pipe among the fuel pipes integrated between the refrigerant pipes to position each refrigerant pipe in a specific shape; and in each of the refrigerant pipes located in the specific shape. For connecting the one end of the refrigerant pipe and the other end of the refrigerant pipe in the step of integrating each refrigerant pipe into one for the refrigerator It provides a process for the production of compressors.

    Hereinafter, the present invention will be described in more detail with reference to FIGS. 5 to 6.
    5 is a perspective view illustrating a condenser for a refrigerator according to the present invention, and FIG. 6 is a flowchart illustrating a process of manufacturing the condenser for the refrigerator according to the present invention. The condenser of the present invention has a thin fin as shown in FIG. 502 is integrally formed between the plurality of refrigerant pipes 501 located in a specific form, one end of one of the refrigerant pipes is connected to one end and the other end of the other refrigerant pipe is connected to each other U-shaped connecting pipe 503 which integrates the refrigerant pipe 501 into one refrigerant pipe, and a vent hole 504 formed at right angles to the longitudinal direction of the refrigerant pipe 501 in each of the thin plates 502. .
    According to the present invention configured as described above, the high temperature and high pressure gas refrigerant compressed by the compressor 4 constituting the cooling cycle flows along the refrigerant pipe 501 of the condenser 5, whereby the air passes between the refrigerant pipes. The heat of the coolant is integrated into one by the U-shaped connecting pipe 503, and heat is radiated to the outside through the thin plate fin 502 integrated between the coolant pipe 501 and the coolant pipe positioned in a predetermined shape. As the gas refrigerant of heat exchanges, it condenses into liquid refrigerant.
    On the other hand, since the fin 502 integrated between the refrigerant pipes 501 is a thin plate, it is understood that the heat exchange efficiency of the refrigerant flowing through the refrigerant pipe 501 is further improved as the heat dissipation area becomes wider. 502 has a plurality of ventilation holes 504 formed at right angles to the longitudinal direction of the refrigerant pipe 501 so that each of the ventilation holes 504 formed in the fin 502 in the process of passing air between the refrigerant pipes 501. As a result, the air boundary layer, which eventually acts as a thermal resistance, continuously breaks, thereby further improving heat exchange efficiency.
    As described above, the present invention condenser extrudes a plurality of coolant tubes 501 such that the thin fins 502 are integrated between the thin fins 502 and the coolant tubes 501 in the thin fins 502. Forming a plurality of ventilation holes 504 at right angles to the longitudinal direction, bending a specific one of the fins 502 in which each of the ventilation holes are formed, and placing each refrigerant pipe 501 in a specific shape; The step of integrating each of the refrigerant pipes 501 into one by connecting one of the refrigerant pipe ends and the other of the refrigerant pipe ends of each of the refrigerant pipes 501 positioned as follows is sequentially performed.
    In more detail, a plurality of coolant tubes 501 having a thin plate fin 502 integrated therebetween are extruded by a mold, and then each fin 502 has a lengthwise direction of the coolant tube 501. A plurality of ventilation holes 504 are formed at right angles by pressing.
    Then, each of the fins 502 is bent to position each refrigerant pipe 501 in a particular shape, and then one of the refrigerant pipe ends of one of each of the refrigerant pipes 501 positioned in the specific shape is different from the other one. When the end of the refrigerant pipe is connected to a member such as a U-shaped connecting pipe 503, each of the refrigerant pipes 501 is integrated into one, and the manufacture of the condenser is completed.
    As described above, the present invention performs a welding operation only when connecting a plurality of refrigerant pipes integrated between the plate-shaped coils during manufacture by a member such as a U-shaped connecting pipe, thereby greatly reducing the workmanship according to manufacturing. In addition, the cost is reduced, as well as the thin plate, so that the heat dissipation area of the refrigerant flowing along the refrigerant pipe in use increases the heat exchange efficiency of the refrigerant due to the movement of the air.
