Description

Radiation Device for Machine Room in Refrigerator

The present invention relates to a refrigerator, and more particularly, to a refrigerator machine room heat dissipation device for efficiently cooling the heat generating parts in the machine room by installing a barrier in the compressor base so as to partition the refrigerator machine room space as small as possible.

A refrigerator is a freezer that supplies cold air into a storage space and maintains food in the storage space at a constant temperature.

The cold air of the refrigerator is generated by the operation of the refrigeration cycle, the refrigeration cycle comprises a compressor, a condenser, a capillary tube, an evaporator. The refrigerant is circulated along the component to change phase and heat exchange with the air circulating in the storage space of the refrigerator to generate cold air.

The compressor and the condenser are installed in the machine room, which is a space provided in the lower rear part of the refrigerator. In a compressor for compressing a gaseous refrigerant and a condenser for condensing the compressed refrigerant, heat is generated during operation. That is, the compressor generates heat in the process of compressing the refrigerant, and heat is released in the process of radiating heat of the refrigerant in the condenser.

And there is a need to cool the heat generated in the compressor and the condenser, which is directly related to the efficiency of the compressor and condenser, and ultimately also to the efficiency of the entire refrigerator. Hereinafter, a heat radiating part heat dissipation device inside a machine room according to the related art will be described with reference to FIG. 1.

As shown in FIG. 1, the compressor 4 and the condenser 6 are mounted on the compressor base 2 of the machine room C. As shown in FIG. In addition, a blowing fan 10 is installed between the compressor 4 and the condenser 6. The blowing fan 10 forcibly blows out the outside air by forcibly blowing out the air in order to radiate the compressor 4 and the condenser 6.

A plate-shaped air guide 12 bent in a cross-section of the letter 'c' surrounds the blower fan 10 and the condenser 6. The air guide 12 serves to centrally guide the air flow generated by the operation of the blower fan 10 to the compressor 4 and the condenser 6.

When the blowing fan 10 is operated by the driving of a fan motor (not shown), external cold air is guided by the air guide 12 and sucked into the condenser 6 in the air guide 12. . External cold air sucked into the condenser 6 dissipates the condenser 6 and is delivered to the blowing fan 10.

The external cold air that radiates the condenser 6 passes through the blower fan 10 and is forcedly blown to the compressor 4 by the blower fan 10. The outside air forcedly blown by the compressor 4 exits the machine room C after dissipating the compressor 4.

However, the machine room heat dissipation structure according to the related art configured as described above poses the following problems.

The machine room heat dissipation device of the prior art has a structure in which a separate air guide 12 is provided. That is, in order to concentrate the air flow formed by the operation of the blower fan 10 to the compressor 4 and the condenser 6, the air guide 12 is separately installed to condenser 6 and the blower fan 10. ) Is configured to surround. According to the configuration of the prior art as described above, there is a problem that the product cost of producing the air guide 12 rises.

In addition, when the blowing fan 10 and the condenser 6 are installed in the air guide 12 as described above, when the blowing fan 10 and the condenser 6 are operated, vibration is generated in the air guide 12. do. In order to prevent the vibration phenomenon as described above, a separate vibration damper (not shown) needs to be attached to the air guide 12, thereby increasing the number of parts and increasing the cost.

In addition, the air guide 12 is mounted to the compressor base 2 by using four screws in the bent portion of the air guide 12 which is in contact with the compressor base 2. Therefore, since four fastening screws are used to fasten the air guide 12, the inconvenience of increasing the number of working hours occurs.

In addition, since all the large space of the machine room C is used, the large and large compressor base 2 should be used. Therefore, a problem arises that the cost of the product rises because of excessive material costs. In addition, since the compressor base 2 is injection molded, if too wide as described above, there is a problem that the strength is weak.

The present invention provides a refrigerator machine room heat dissipation device having improved cooling performance by a simple structure by installing a barrier on one side of the machine room so as to minimize the refrigerator machine room space while solving the problems of the prior art as described above. It aims to do it.
