Description

Cooling system of refrigerator press chamber and refrigerator

technical field

The utility model belongs to the technical field of refrigerators, and in particular relates to the structural improvement of the cooling system of a refrigerator press chamber.

The main components inside are compressor, condenser, water tray and cooling fan. , constituting the heat dissipation system of the press chamber.

The heat dissipation fan of the existing heat dissipation system of the compressor chamber mainly adopts the axial flow fan, and the position of the fan relative to the compressor and the condenser generally has the following two forms.

(1) The compressor 1 and the condenser 2 are located on the air outlet side, and the axial flow fan 3 is located on the air inlet side, as shown in Figure 1. The fan with this structure directly blows air to the condenser and compressor, resulting in a large pressure loss, and the airflow directly hits the solid wall, resulting in a large speed loss and high aerodynamic noise. Moreover, due to the large resistance of the condenser, the heat dissipation of the compressor is not used.

(2) The compressor 1 is located on the air outlet side, the condenser 2 is located on the air inlet side, and the axial flow fan 3 is located between the compressor 1 and the condenser 2. Due to the small air intake in the middle of the axial flow fan and more air intake around the side, the air intake at the side of the condenser will be uneven and the heat dissipation effect of the condenser will be reduced.

At the same time, there are two types of structures, the air outlet direction of the axial flow fan is 90 degrees to the air outlet, the frontal impact loss is large, the distance between the air outlet of the compressor chamber and the air outlet of the fan is far, and there is a lot of backflow in the middle, which reduces the heat dissipation effect and increases aerodynamic noise.

With the increase in the popularity of refrigerators, users have higher and higher requirements for refrigerator energy consumption and noise. In order to improve the core competitiveness of products, the design improvement of the cooling system of the refrigerator compressor compartment has become a technical issue that needs to be solved urgently.
