摘要
为了提高热电制冷系统热端的散热效率,在半导体制冷片的热端采用一种集成多孔表面的多孔强化沸腾散热器.在相同环境温度下试验对比使用多孔强化沸腾散热器、风冷式散热器、热管散热器和水冷式散热器的热电制冷系统的性能,并分析不同环境温度下多孔强化沸腾散热器的散热能力.试验结果表明,多孔强化沸腾散热器可以强化热电制冷机中半导体制冷片的热端散热,在一定的输入功率范围内,安装有多孔强化沸腾散热器的制冷机的制冷量大于安装风冷式、热管和水冷式散热器的制冷机,可以满足热电制冷系统热端散热的要求,但是环境温度的升高会降低多孔强化沸腾散热器的散热能力.
In order to improve the refrigeration efficiency of the hot terminal of ther-moelectric refrigeration system,a micro-porous enhanced boiling radiator with miro-porous surface is applied to the hot terminal of semiconductor chilling plate.The perform-ances of thermoelectric refrigeration system using micro-porous enhanced boiling radiator,air-cooled radiator,heat pipe radiator and water-cooled radiator respectively under thesame ambient temperature are compared experimentally,and the heat dissipation capacities of themicro-porous enhanced boiling radiator under different ambient temperatures are analyzed.Theexperimental results show that the micro-porous enhanced boiling radiator can enhance theheat dissipation of the hot terminal of semiconductor chilling plate in the thermoelectricrefrigerator.Within a certain input power range,the cooling capacity of a refrigerator withthe micro-porous enhanced boiling radiator is greater than that of a refrigerator with air-cooled/heat pipe/water-cooled radiators,which can meet the heat dissipation requirementsof the hot terminal of the thermoelectric refrigeration system.The increase of ambienttemperature will reduce the heat dissipation capacity of the micro-porous enhanced boilingradiator.
