Abstract

The embodiment of the invention discloses an evaporator deicing device comprising a power source, a heating element connected to the power source and a processor connected to the heating element to beused for controlling the working time length of the heating element. The heating element is a thick film heater; and as the thick film heater has the good thermal conversion efficiency, compared withheating elements such as electric heating tubes or electric heating wires, the thick film heater can achieve the same deicing effect at the lower surface temperature, and the thick film heater can bearranged on a heat dissipating fin of an evaporator to be used for heating the heat dissipating fin for deicing. Since the thick film heater is in direct contact with the heat dissipating fin, generated heat can be transmitted to an icing portion to the maximum extent for conduction and heat transferring, the evaporator deicing efficiency is greatly improved, the good deicing effect can be achieved in a conduction heat transferring manner, and the condition of incomplete deicing is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of evaporator ice melting, in particular to an evaporator ice melting device. Background technique [0002] The evaporator is the main heat exchange device of the refrigeration system. It is a device that exchanges heat between the refrigerant and the external medium flowing through the surface of its components. During operation, the refrigerant in the evaporator changes from a liquid state to a gas state to achieve the effect of cooling. [0003] The evaporator includes heat dissipation fins and refrigerant pipes. Taking a refrigerator as an example, frost will condense on the heat dissipation fins of the evaporator during the operation of the refrigerator. As the thickness of the frost layer increases, it will directly lead to a decrease in the heat transfer efficiency of the evaporator. increase in energy consumption. In order to reduce the impact caused by condensation on the evaporator, in the prior ...
