Paper Abstract

This paper presented the variation law of temperature in three-dimensional space, which is cooled by the refrigeration provided by the cold side of a semiconductor. It's tested under the conditions of the natural and forced convection in a semiconductor refrigeration device under steady working conditions. The mathematical model of the temperature field of the semiconductor refrigeration device is described, and a numerical study on the temperature profile in a semiconductor refrigeration device was carried out using this model. Numerical simulation is applied to the present thermostated container. Then the space tempo direction in the case of the gas flows, distribution of pressure in each point, the data of three-dimensional temperature field, etc. are gained. The problems in present thermostated containers are discussed, the factor influencing current air organization and temperature field are analyzed. The experimental results show that forced convection is of benefit to the cold transfer and to the rise of refrigeration rate.
