Directly cooling refrigerator and its mounting method

Abstract

A direct cooling type refrigerator capable of increasing the heat exchange performance of a refrigerant, thereby rapidly cooling its storage compartment. The refrigerator includes an outer casing defining an appearance of the refrigerator, an inner casing arranged within the outer casing, and defined with a storage compartment, an insulator interposed between the outer casing and the inner casing, a compressor for compressing a refrigerant, and an evaporator arranged to be in contact with the inner casing, and adapted to cool the inner casing in accordance with evaporation of a refrigerant passing therethrough.

Description

technical field [0001] The invention relates to a direct-cooling refrigerator, in particular to a direct-cooling refrigerator in which the contact area between an inner casing forming a storage room and an evaporator is large, thereby rapidly cooling the storage room. Background technique [0002] In general, refrigerators are classified into two types according to their cooling methods. That is, a direct cooling type refrigerator that cools the storage room by directly cooling the inner case of a storage room forming a freezer or a refrigerating room using an evaporator, and a cooling fan that supplies cold air generated by heat exchange with the evaporator to the storage room Indirect refrigerator. [0003] Such as figure 1 with figure 2 As shown, a common direct-cooling refrigerator comprises an outer casing 2 forming the outer shape of the refrigerator; an inner casing 4 forming a storage room F arranged inside the aforementioned outer casing 2; filling the aforement...

AI Technical Summary

Problems solved by technology

[0009] However, in the evaporator of this direct cooling refrigerator, due to the non-uniform expansion degree caused by the high-pressure air, problems such as refrigerant clogging or pressure drop on one side of the refrigerant flow path 36 may occur.
