Semiconductor defrosting heater and refrigeration equipment

Abstract

The invention provides a semiconductor defrosting heater and refrigeration equipment, wherein the semiconductor defrosting heater comprises a heat dissipation part, a semiconductor refrigeration assembly and a refrigeration part, wherein the heat dissipation part, the semiconductor refrigeration assembly and the refrigeration part are sequentially arranged far away from an evaporator, and the semiconductor refrigeration assembly is connected with the heat dissipation part and the refrigeration part respectively through insulation heat conductors. By means of the technical scheme, on one hand, the effect of defrosting the evaporator is achieved, and compared with an existing defrosting heating pipe, the defrosting efficiency is improved, and electric energy is saved; on the other hand, the direct current needed by the semiconductor refrigeration assembly is under safe voltage, security and reliability are high, and potential safety hazards existing in the defrosting process of the defrosting heating pipe are reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a semiconductor defrosting heater and a refrigeration equipment. Background technique [0002] related technologies, such as figure 1 As shown, the defrosting heater uses the defrosting heating tube 102 to periodically heat and defrost the evaporator 104. Although the defrosting heating tube 102 solves the problem of manual defrosting, in the actual defrosting heating process, the defrosting heating Tube 102 still has the following drawbacks: [0003] (1) When the defrosting heating tube 102 heats and defrosts, the temperature inside the refrigerator and other refrigeration equipment will also rise accordingly, which affects the user experience; [0004] (2) The defrosting heating pipe 102 is installed at the bottom of the evaporator 104, and the heat of the defrosting heating pipe 102 radiates to the surroundings, resulting in a low heat utilization rate of the...
