A refrigerator is a refrigeration device that can maintain a constant low temperature in a refrigerator. The working principle is that the refrigerant is evaporated and cooled in the refrigerating system to reduce the temperature in the refrigerator, and the heat is dissipated to the environment through the external condenser to realize the low temperature in the refrigerator. The refrigerator condensing unit is therefore an essential component of a refrigerator. With the development of embedded refrigerators with large volume ratio and high energy efficiency in recent years, refrigerator manufacturers also invest a lot of resources in the research on condensation heat dissipation devices.

The refrigerator condenser is generally divided into three mounting modes, one mode is that the condenser is embedded and attached to a side plate of a refrigerator body and self-heating heat dissipation is carried out by means of a side wall, the method is low in cost, attractive in appearance, limited in heat dissipation capacity and relatively poor in heat dissipation effect, and the condenser is mainly used for a small-volume refrigerator and cannot realize embedded design; the second type is externally hung on the back or the bottom box body part of the refrigerator for heat dissipation, the refrigerator mainly takes an outlet as a main part, is not attractive in appearance and poor in heat dissipation effect, but can be used for attaching vacuum heat insulation plates on two sides, so that the energy efficiency of the whole refrigerator is improved, and the standardized design of the box body is facilitated; the third is that the heat exchanger is arranged in a compressor chamber and forcibly exchanges heat through a fan, and the way is mainly used for a large-volume refrigerator and has good heat dissipation effect but high cost.
