BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat sink of a built-in refrigerator for improving heat dissipation in a machine room by installing a suction duct in a lower part of a refrigerator body installed in a built-in cabinet.

In general, a refrigerator is a device that is used for long-term storage of fresh food, and can be broadly divided into a main body having a food storage room for refrigerating and freezing food and a refrigeration cycle for dissipating the food storage room.

Since the refrigerator basically has a certain size, when the refrigerator is installed on one wall of a kitchen or living room, the refrigerator is seen as an outer shape protruding from the wall by the size thereof. There was a problem that the installation structure is not aesthetically good and its utilization is reduced in space.

As an example for solving this problem, as shown in FIG. 1, the refrigerator may be installed in the built-in cabinet 10 as one built-in furniture or installed in a sink.

The built-in refrigerator is divided into a machine room in which a main body is installed with a storage chamber and a refrigerant circulation device for maintaining the inside of the storage chamber at a low temperature. When the built-in refrigerator is installed, heat exchange is smoothly performed in a machine room where air flow is likely to be blocked due to the built-in structure, and a technology for more effectively dissipating heat generated has emerged as an important problem.

2 is a schematic configuration diagram showing a conventional built-in refrigerator.

Referring to FIG. 2, the refrigerator main body 11 installed in the built-in cabinet 10, the baseboard 14 installed in the lower part of the front surface, the machine room 15 provided on the rear surface of the refrigerator main body 11, and the refrigerator main body ( 11 is a heat dissipation passage consisting of a suction passage 18a communicated through the lower portion of the fingerboard 13 supporting the base plate 13 and the vent hole 14a of the base 14 and a discharge passage 18b located at the rear of the refrigerator body. It is composed.

A brief description of the built-in refrigerator as described above is as follows.

1 and 2, in the built-in cabinet 10, a refrigerator main body 11 is installed in a space provided as a built-in furniture, and the refrigerator main body 11 is provided with a front door panel 12 and a rear wall surface ( 17) between the lower fingerboard 13 and the base 14 and the upper cabinet. Here, the base 14 is installed to improve the appearance of the lower part of the built-in cabinet 10 and block the inflow of dirt.

In addition, a lower portion of the rear surface of the refrigerator main body 11 is provided with a machine chamber 15 protected by the back cover 16, and outside air is sucked in and discharged into the machine chamber 15, and a compressor, a condenser, and a blower fan are disposed therein. This is made up.

The built-in cabinet 10 generates heat dissipation passages 18a and 18b to effectively dissipate heat generated inside the machine room 15. The heat dissipation passage is divided into a suction passage 18a at the bottom of the refrigerator main body and a discharge passage 18b at the rear of the refrigerator main body.

Here, outside air flows into the vent hole 14a of the base plate 14 installed in the lower part of the front surface of the built-in sheet 10, and the introduced air is the fingerboard 13 and the bottom surface installed in the lower portion of the built-in sheet 10. It is discharged to the outside through the discharge flow path 18b between the refrigerator main body 11 and the wall surface 17 through the suction flow path 18a between.

In this structure, when the built-in refrigerator is operated, the compressor, the condenser, and the blowing fan provided in the machine room 15 installed at the lower rear side of the refrigerator main body 11 are operated. At this time, the air sucked through the suction flow path 18a located in the lower part of the refrigerator main body is guided inside the machine room and passes out through the discharge path at the rear of the refrigerator main body through the condenser and the blowing fan.

3 is a front view illustrating a machine room structure of a conventional built-in refrigerator.

Referring to FIG. 3, a compressor 15a on one side, a condenser 15b on the center, and a blower fan 15c on the other side are installed in the machine room 15 installed at the lower rear of the refrigerator main body, and a blower fan 15c may be installed. When activated, the outside air is sucked through the suction hole 16a of the back cover 16, and the air discharged by the blower fan 15c is heat exchanged with the condenser 15b and the compressor 15a, and then the back cover 16 It exits the discharge hole 16b of the).

At this time, the heat exchanged air inside the machine room 15 is discharged to the outside through the discharge passage (18b), and at the same time has a circulation process in which air is introduced through the suction passage (18a).

Conventionally, since suction and discharge in the machine room of the refrigerator main body are the same, a circulation of the flow, that is, the discharged flow is introduced again through the compressor, thereby degrading the heat transfer efficiency of the condenser.

In addition, when the refrigerator is installed in the built-in cabinet, the inflow structure of the flow path into the machine room is limited by the fingerboard installed at the bottom of the refrigerator for supporting heat dissipation, thereby making it difficult to form an efficient heat dissipation structure.
