Air-cooled type refrigerator with heat pipe type heat storage and frost removal mechanism

Abstract

The invention relates to an air-cooled type refrigerator with a heat pipe type heat storage and frost removal mechanism. The air-cooled type refrigerator comprises a refrigerator body, a condenser, an evaporator, a fan, a water receiving tray, a water drain pipe, more than one gravity assisted heat pipe and an annular heat pipe, wherein a heat storage chamber is formed in the refrigerator body between the condenser and the evaporator and is filled with a phase change heat storage material; a gravity assisted heat pipe evaporation section of each of the more than one gravity assisted heat pipe is inserted in a condenser coil of the condenser, a condensation section of each of the more than one gravity assisted heat pipe extends into the heat storage chamber and is wrapped with the phase change heat storage material; an evaporation section of the annular heat pipe is located in the heat storage chamber, one part of a condensation section of the annular heat pipe is attached to the evaporator and used for removing frost on the evaporator of the refrigerator, and the other part is attached to the water receiving tray and used for heating the water receiving tray. According to the air-cooled type refrigerator, waste heat released by the condenser is stored by the phase change heat storage material and used for efficiently removing frost on the evaporator of the air-cooled refrigerator, so that the energy consumption of the refrigerator is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of household appliance refrigerators, and in particular relates to an air-cooled refrigerator. Background technique [0002] The surface of the evaporator of the air-cooled refrigerators put into use in the market today will have the problem of frosting. This is because the refrigerator absorbs the heat in the refrigerator box through the evaporator inside the refrigerator to achieve the cooling effect. The surface temperature will be lower than 0°C, and the moisture in the air in the refrigerator will slowly form a layer of frost on the surface of the refrigerator evaporator. Therefore, the air-cooled refrigerator must perform periodic defrosting operations after running for a period of time. [0003] Generally, the defrosting process of an air-cooled refrigerator is controlled by the refrigerator control system at the stage when the compressor stops running after the refrigerator has been working for a pe...

AI Technical Summary

Problems solved by technology

[0004] During the defrosting operation of the refrigerator, it is necessary to heat the evaporator and the water tray of the refrigerator at the same time. The heating process will consume more energy, and the long-term defrosting operation will cause the temperature inside the refrigerator to rise too much, which will not only increase the energy consumption of the refrigerator In severe cases, it will affect the ability of the refrigerator to store food and shorten the time for food preservation in the refrigerator
