Description of the Related Art Regarding the heat dissipation form of a conventional refrigerator, heat dissipation in a refrigeration cycle in a relatively small size (class smaller than 400 liters) will be described with reference to FIGS. According to this, the high-temperature, high-pressure gas refrigerant discharged from the compressor 1 passes through the pedestal pipe 3 under the evaporation tray, and is condensed by the heat radiating pipe 5 and the clean pipe 7 arranged mainly inside the side surface of the refrigerator main body. To be done. The refrigerant that has condensed and radiated heat to reduce the enthalpy reaches the capillary tube 9 and expands to a low pressure state, evaporates in the evaporator 11 and lowers the ambient temperature of the evaporator 11. The refrigerant discharged from the evaporator 11 is sucked into the compressor 1 via the accumulator 13, and again becomes high-temperature, high-pressure heating steam and circulates in the cycle.

採られていなかった。By the way, the size of refrigerators has increased in recent years, and with this, the capacity of compressors used has increased, and the amount of heat radiation required has also increased. For the heat radiation of the compressor, when the required heat radiation amount is small, the heat radiation due to natural convection or radiation was sufficient, so that no particular measure was taken as in the conventional example.

て行っている。However, in a large-sized refrigerator, due to an increase in the required heat radiation amount of the compressor, cooling air is blown to the compressor by a cooling fan to radiate the heat by forced convection, as shown in FIG.
Also, as shown in FIG. 10, an oil cooler system is used in which the discharge gas from the compressor 1 is cooled by natural convection through the pedestal pipe 3 and then returned to the compressor 1. further,
When the amount of heat radiation is required, the above two methods are combined.

考えられる。On the other hand, the use of specific Freon (CFC) becomes a problem due to ozone layer depletion, and the use of alternative Freon is required. There are various possible alternative CFCs, but it has been found that when R22, which has a proven record in air conditioners and the like, is used in a low-temperature refrigeration cycle for a refrigerator, the required heat radiation amount of the compressor increases. For this reason, it is necessary to positively use the compressor cooling means such as the oil cooler system described above, and further increase the heat radiation amount of the pedestal pipe 3 of FIG. 9 which serves as an auxiliary radiator for cooling the discharge gas of the compressor. Since it is required, a heat radiation method by forced air cooling of the auxiliary radiator can be considered.

方法も考えられる。In addition, since the heat leakage to the inside of the refrigerator is reduced,
The heat radiating pipe 5 shown in FIG. 7 or 9, which is the main heat radiator, is placed in the space of the machine room or the bottom of the refrigerator against the so-called inner pipe capacitor provided on the side of the refrigerator body, and heat is radiated by forced air cooling by a fan. A method of making it possible is also considered.

ることも可能である。In these radiators, so-called wire capacitors may be used, in which a thin iron wire is welded to a bent iron pipe through which a refrigerant passes to expand the heat transfer area. An example of the method for manufacturing the wire capacitor will be described.
First, an iron pipe for refrigerant piping is bent repeatedly on one plane to a predetermined width and pitch as in the saucer pipe 3 of FIG. 7, so that the width and the pipe pitch become constant,
Set it on the jig that fixes the bent part. In this state,
Iron thin wires (wires) wound in a coil shape arranged above and below the iron pipe are sequentially drawn out, and the drawn thin wires are sandwiched from above and below the iron pipe and fixed by welding. After welding,
The wire capacitor is completed by cutting the thin wire. The thin wire may have a certain length that has been cut in advance. Further, it is possible to manufacture a wire capacitor by welding the same wire together to two types of bent iron pipes.

となって好ましいものではない。However, the wire capacitor thus manufactured is arranged in the space above the auxiliary radiator for cooling the discharge gas of the compressor and in the machine room or the bottom of the refrigerator. When used as an integrated radiator, the two radiators, the auxiliary radiator and the main radiator, differ greatly in the temperature of the refrigerant flowing inside, so heat conduction causes the main radiator at a low temperature to become hot. Since it was heated by the auxiliary radiator of No. 2, it was not possible to integrate both, and it was necessary to install both separately. If both are installed separately, an extra space is required, which is not preferable.

に跨って前記伝熱部材を設けた構成としてある。In order to achieve the above object, the present invention provides a heat exchanger in which a bent refrigerant pipe is provided with a heat transfer member to cool the refrigerant discharged from a compressor. The piping is composed of an auxiliary heat radiation portion that introduces the discharged refrigerant, cools it, returns it to the compressor, and cools the compressor, and a main heat radiation portion that introduces the refrigerant returned from the auxiliary heat radiation portion to condense it. In addition, the two heat radiating parts are arranged so as to be separated from each other by a predetermined distance, and the heat transfer member is provided across the both heat radiating parts.

Therefore, heat conduction between them is suppressed.

The high-temperature, high-pressure gas refrigerant from the above passes through the evaporation dish pipe 23, enters the auxiliary heat radiating portion 41 of the wire condenser 19, and returns to the oil cooler 39 of the compressor 15 in a cooled state to cool the compressor 15. The refrigerant discharged from the oil cooler 39 enters the main heat dissipation portion 43 of the wire condenser 19 and is cooled, and further cooled in the clean pipe 27 and condensed. The refrigerant, which has been radiated and condensed to reduce the enthalpy, expands through the dryer 29 and the capillary tube 31, expands to a low pressure state, evaporates in the evaporator 33, and lowers the temperature around the evaporator 33. The refrigerant discharged from the evaporator 33 is sucked into the compressor 15 via the accumulator 35 and becomes high-temperature, high-pressure heating vapor, and circulates in the cycle.

固定を同時にできるので、製造が容易となる。In such a refrigerant circulation process, in the wire condenser 19, the auxiliary heat radiating portion 41 and the main heat radiating portion 4 are formed.
3 has a large temperature difference, but these two are spaced apart from each other at a predetermined interval, and since the wire 37 itself between them is cooled, the heat of the high temperature auxiliary heat radiating portion 41 is the low temperature main heat radiating portion 43. Therefore, the condensation of the refrigerant in the main heat radiation portion 43 is desired. Further, in the wire capacitor 19, since the auxiliary heat radiating portion 41 and the main heat radiating portion 43 are structurally integrated by the wire 37, the installation space is small, and both heat radiating portions 4 are required for manufacturing.
Since the wire 37 can be welded and fixed to the iron pipes 36 of Nos. 1 and 43 at the same time, manufacturing becomes easy.

The refrigerant cooled through 1 is returned to the oil cooler 39,
Since it is actively cooled by a so-called oil cooler system and further cooled by natural convection by the cooling fan 21, it increases the required heat radiation amount due to the increase in the capacity of the compressor accompanying the enlargement of the refrigerator, and substitutes for ozone layer depletion. It becomes possible to sufficiently cope with the increase in the required heat radiation amount of the compressor due to the use of Freon R22. 4 to 6 show a second embodiment of the present invention. In this embodiment, the auxiliary heat dissipation part 4
1 to the wire 37 between the main heat dissipation portion 43,
In order to structurally integrate the two heat radiating portions 41 and 43 with each other, only the minimum necessary amount is left and the others are cut. As a result, the heat dissipating portions 41, 43 are thermally separated from each other, and heat conduction between them is suppressed. In this case, if it is not necessary to structurally integrate the heat radiating portions 41 and 43, the wire 37 between the heat radiating portions 41 and 43 is formed.
May be cut off.
