Problems solved by technology

The refrigerating evaporator of the existing direct-cooling refrigerator usually adopts a plate-tube or wire-tube design, so that when using the existing direct-cooling refrigerator, the surface of the refrigerating evaporator will be in contact with the inside of the freezing compartment. The hot and humid air is in direct contact, and because the density of the hot air is lower than that of the cold air, a large amount of hot and humid air will gather in the front and upper part of the freezer compartment, resulting in obvious local frosting.
With the increase of the service cycle, the temperature in the freezer room will easily rise due to the thick frost layer, which will not only cause the cooling performance of the direct cooling refrigerator to decline, but also cause high power consumption, seriously affecting the User's normal use

Abstract

Disclosed is a direct-cooling refrigerator, comprising a freezing liner (20), wherein an evaporation tube group is arranged between the freezing liner (20) and a shell of the direct-cooling refrigerator. The evaporation tube group comprises a first evaporation tube (30) and a second evaporation tube (40), the first evaporation tube (30) being of a liner winding type.

Description

technical field [0001] The invention relates to a direct cooling refrigerator, in particular to an evaporation tube group of the direct cooling refrigerator. Background technique [0002] A refrigerator is a device that uses the cooling effect of the refrigerant in the refrigeration circuit during compression, condensation, expansion, and evaporation to maintain the interior of the refrigerator at a low temperature, thereby preserving food. [0003] The direct-cooling refrigerator maintains the temperature in the box at a low temperature by continuously driving the refrigeration circuit. The refrigerating evaporator of the existing direct-cooling refrigerator usually adopts a plate-tube or wire-tube design, so that when using the existing direct-cooling refrigerator, the surface of the refrigerating evaporator will be in contact with the inside of the freezing compartment. The hot and humid air is in direct contact, and because the density of hot air is lower than that of c...
