Abstract

A cooling device, wherein a compressor, a condenser, a capillary, an evaporator, and an accumulator are connected to each other in this order and a refrigerant is circulated therethrough. A U-trap tube is installed between the evaporator and the accumulator.

Description

Technical field [0001] The present invention relates to a cooling device that reduces the sound of refrigerant flowing in a cooling pipe in a refrigeration cycle, and a refrigerator using the cooling device. Background technique [0002] Figure 6 It is a freezing cycle diagram of an existing refrigerator. The refrigeration cycle is composed of a compressor 36, a condenser 37, a dryer 38, a capillary tube 39, an evaporator for the refrigerator compartment (hereinafter referred to as an evaporator) 33, an evaporator for a freezer compartment (hereinafter referred to as an evaporator) 34, and an accumulator 35 And the piping connecting them. [0003] Figure 7 Is showing Figure 6 An enlarged view of the accumulator 35 and the evaporator 34 in. The refrigerant in the tube of the evaporator 34 during the cooling operation forms a gas-liquid two-phase flow of the gas refrigerant 45 generated by evaporation and the liquid refrigerant 46 that is not evaporated. The liquid refrigerant...
