Direct cooling type refrigerator and evaporating pipe fixing method in the refrigerator

摘要

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 (52) defining an appearance of the refrigerator, an inner casing (54) arranged within the outer casing (52), and defined with a storage compartment, an insulator interposed between the outer casing (52) and the inner casing (54), a compressor (56) for compressing a refrigerant, and an evaporator (62) arranged to be in contact with the inner casing (54), and adapted to cool the inner casing (54) in accordance with evaporation of a refrigerant passing therethrough.
