Description

Condenser assembly, heat dissipation system, box body and installation method

Technical Field

The invention belongs to the technical field of refrigerator heat dissipation, and particularly relates to a condenser assembly, a heat dissipation system, a box body and an installation method.

Background

In order to reduce the overall dimension and increase the heat dissipation capacity of the existing household refrigerator, a heat dissipation system is generally arranged in a compressor bin of the refrigerator, and heat dissipation is realized in a forced air circulation mode. The heat exchange is realized by a mode that a condenser and a compressor are respectively arranged at two sides and forced convection is carried out in the middle through a fan in the industry. In this way, the air inlet is generally arranged on one side of the rear cover of the press bin, and the air outlet is arranged on the other side of the rear cover of the press bin. Because the air inlet and the air outlet are both arranged on the rear cover of the press, the distance between the air inlet and the air outlet is small, the short circuit of an air path is easily formed, and the air blown out from part of the air outlet easily flows back to the air inlet, and does not effectively exchange heat, thus being unfavorable for the refrigeration performance of the refrigerator. The chinese invention patent CN110375506A discloses a refrigerator for dissipating heat from the bottom, in which air enters a press chamber through an air inlet from one side of a wind strip, cools a condenser, blows to a compressor under the action of a convection fan, and finally flows out from an air outlet to the other side of the wind strip. The condenser and the compressor are transversely arranged in the press bin side by side. The compressor rear cover can also be provided with a plurality of vent holes for air inlet and air outlet.

However, the condenser is not described in the patent, and is only a general rectangular parallelepiped structural member as viewed from the drawings. The condenser is an important component of the heat dissipation system, and the technical states of the shape, the structure, the installation mode and the like of the condenser greatly influence the cooling performance of the whole machine. Air enters the press bin from one side of the wind shielding strip through the air inlet, cools the condenser, blows to the compressor under the action of the convection fan and finally flows out of the air outlet to the other side of the wind shielding strip. Because the air inlet and the air outlet are both arranged on the rear cover of the press, the distance between the air inlet and the air outlet is small, and because of the common vent holes, the air path short circuit is easy to form, and the air blown out from part of the air outlet is easy to flow back to the air inlet, and the air outlet does not effectively exchange heat, thereby being unfavorable for the refrigeration performance of the refrigerator. The condenser and the compressor are transversely arranged in the press bin side by side, and due to the transverse arrangement, the size and the length of the condenser are limited, the heat dissipation area is also limited, and the heat dissipation effect cannot be fully exerted. Therefore, in a limited space, how to increase the effective heat dissipation area (volume) of the condenser becomes one of the key factors for improving the performance of the refrigeration system of the refrigerator.
