Coiled pipe evaporator and refrigerator

Abstract

The invention relates to the technical field of refrigerating equipment, and provides a coiled pipe evaporator and a refrigerator. The coiled pipe evaporator comprises a first pipe section located on the top face of an inner container, second pipe sections located at the bottom face of the inner container and third pipe sections used for connecting the first pipe section and the second pipe sections. The density of the side, close to a side opening door, of the first pipe section is larger than that of the side, far away from the side opening door, of the first pipe section. The second pipe sections are close to one another to form a pipe section set. The density of the side, close to the side opening door, of the pipe section set is larger than that of the side, far away from the side opening door, of the pipe section set. The refrigerator adopting the coiled pipe evaporator can effectively eliminate the problem that temperature in a freezing chamber of a refrigerator is not uniform, and accordingly storage quality of food is guaranteed, and power consumption of the refrigerator is lowered.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a coiled tube evaporator and a refrigerator. Background technique [0002] In order to increase the effective volume of the refrigerator freezer, more and more refrigerator freezers use the coiled tube evaporator 3 for refrigeration and cooling. Moreover, the temperature of the freezer can reach below -6°C, below -12°C and below -18°C according to the freezing star rating. [0003] See figure 1 , the liner 1 of the refrigerator freezer is a cuboid barrel structure, and the coiled tube evaporator 3 is mainly composed of evaporated aluminum tubes surrounding the outer surface of the liner 1 at a certain distance. Specifically, the evaporated aluminum pipes surround the top surface, bottom surface, left side and right side of the inner container 1 . [0004] When the refrigerator is working, the refrigerant evaporates and absorbs heat in the evaporating aluminum t...

AI Technical Summary

Problems solved by technology

[0005] The disadvantage of the existing technology is that the number and arrangement spacing of the evaporation aluminum tubes on the top, bottom, left and right sides of the freezing chamber are the same, so the heat transfer rate on the four sides of the freezing chamber is the same.

However, when the refrigerator is refrigerated, due to the influence of the sinking of the cold air, there is a temperature difference between the upper and lower temperatures of the freezer compartment and the upper part has a higher temperature while the lower part has a lower temperature.

In addition, the refrigerator door seal is used to seal the side door 2 and the box body. Compared with the heat insulation layer, the refrigerator door seal has a large amount of cold leakage, resulting in a high temperature in the part of the freezer near the side door 2.

The uneven temperature of the above-mentioned freezing space will not only affect the storage quality of food, but also increase the energy consumption of the product
