Description

a refrigerator Technical field

The invention relates to the field of home appliances, and in particular to a refrigerator.

Background technique

At this stage, the overall development direction of refrigerators is thin-walled, fully embedded and intelligent. The purpose of thin-walled and fully embedded is to improve space utilization. The reduction of placement space and the weakening of air mobility inevitably lead to the problem of heat dissipation difficulties for refrigeration devices. The heat dissipation of the refrigeration device not only determines the refrigeration performance of the refrigerator, but also determines energy consumption, service life, user safety, etc.

At present, the condenser is generally placed at the bottom of the back of the refrigerator, providing side air inlets, fans, and rear air outlets to form a heat dissipation channel. For a fully embedded refrigerator, this heat dissipation structure has poor heat dissipation effects because many sides are closed. The service life and safety of refrigerators have certain limitations, and poor heat dissipation directly restricts the development of fully embedded refrigerators. Nowadays, built-in refrigerators are becoming more and more common in family life. However, the refrigerators installed in this way do not have side entry and exit conditions, which leads to an increase in the air flow resistance between the outside air and the compressor compartment, resulting in the problem of deterioration of condenser heat dissipation. , affecting the performance of the refrigerator.
