The Heat Transfer Analysis Of Smiulation And Experimenal Study Of Thermoelectric Refrigertion

The main factors of affecting the thermoelectric cooler refrigeration isthe hot-cold side heating transferd coefficient and the working current performance.Through changing the size of the hot-cold surface and adjusting the current of thethermoelectric cooler to the temperature of the cold surface heat transfer temperaturecurve when the thermoelectric materials is constant and discussing the impact ofcurrent and heat transfer coefficient of the thermoelectric cooler.On the basis of previous studies of thermoelectric cooling plate,through of com-puter simulation and theoretical calculation and experimental study,discussing thehot-cold surface by the natural convection and the cold surface touching the humanbody and the cold surface in the natural convection,the hot surface with forcedconvection.Through the three conditions of the refrigeration for performancecomparison, Computer simulation, to simulate the three conditions, the coolingcharacteristics and hot side heat transfer coefficient of the thermoelectric cooling plate,the relationship of the current. In the theoretical calculations, the establishment of thecold end of the refrigeration plate heat exchanger equations, the amount of cooling ofthe semiconductor element equation and heat production equation, the use of the VBsoftware programming Computing, access to the hot end cooling conditions, cold sideto achieve the lowest refrigeration temperature. In order to verify the accuracy of thesimulation calculations, build a thermoelectric cooling test bed for a variety ofconditions, the application of experimental research, and experimental data withcomputer simulation to compare.Through comparison and analysis of the findings of three thermoelectriccooling plate three conditions have been the main performance parameters of the coldjunction temperature, cooling capacity with the input the current strength andrefrigeration board of the hot end of heat changes in the law, and a preliminarydiscussion of the thermoelectric cooler used in the home seat, cold end and thefeasibility of natural convection are the hot end of the hot plate, providing a solidfoundation for thermoelectric cooling is applied to the design and control of thedomestic seating.
