Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 3 and 4.

The refrigerator of the present invention includes a main body (not shown) that forms a storage space separated into a refrigerating compartment and a freezing compartment, and a door (not shown) mounted to one side of the main body to open and close the refrigerating compartment and the freezing compartment.

And the back of the main body has a built-in mechanism having a refrigeration cycle for cooling the refrigerating compartment and the freezing compartment.

As shown in FIG. 3, the apparatus circulates a compressor 110 that compresses a refrigerant, and circulates a high temperature refrigerant compressed by the compressor 110 to prevent dew from forming on the corners of the refrigerator contacting the door. And an evaporator 130 for cooling the refrigerating compartment and the freezing compartment of the main body through heat exchange with a hot pipe 120 and a refrigerant introduced after passing through the hot pipe 120.

Here, a heat radiating unit 200 is installed between the compressor 110 and the hot pipe 120 to radiate and cool the refrigerant having a high temperature compressed by the compressor 110.

The heat dissipation unit 200 is for dissipating the high temperature refrigerant passing through the compressor 110 by heat exchange with external air. The heat dissipation unit 200 is installed outside the refrigerator, and both ends thereof are connected to the compressor 110 and the hot pipe 120, respectively.

When doing the kitchen in the winter, the heat dissipating unit 200 is taken out to the sole support plate. By using it, the trouble of having to provide a separate heating device can be eliminated.

On the other hand, Figure 3 is designed so that the refrigerant from the compressor 110 passes through the heat dissipation unit 200 first and then passes through the hot pipe 120 to the evaporator 130, so that both ends of the heat dissipation pipe 210 are respectively compressed. Although connected to the 110 and the hot pipe 120, depending on the design, the refrigerant from the compressor 110 may be introduced into the heat dissipation unit 200 through the hot pipe 120 first, in this case, the heat dissipation unit ( Both ends of the 200 are connected to the hot pipe 120 and the evaporator 130.
