Abstract

A direct working medium immersion type thermoelectric refrigerating system is composed of thermoelectric refrigerator, radiator and working medium and features that the heat exchanging chamber in the heat radiator for the hot-end plate of said thermoelectric refrigerator is a sealed cavity containing said working medium, in which said hot-end plate is immersed for transferring its heat to the radiator for heat exchange. Its advantags are high refrigerating efficiency and cold quantity, and high reliability.

Description

technical field [0001] The invention relates to the field of thermoelectric refrigeration and heat transfer, in particular to a working fluid direct immersion thermoelectric refrigeration device. Background technique [0002] Due to the small area of ​​the thermoelectric refrigerator itself and the high heat flux density, the heat pipe radiator developed by using the heat pipe heat transfer technology plays an important role in the efficient transmission of heat. And widely used in thermoelectric refrigeration products. At present, there are three forms of heat dissipation at the hot end of the thermoelectric cooler: 1. Heat transfer through a plane of the evaporation chamber and the hot end of the thermoelectric cooler, and the working medium gas and liquid coexist in the evaporation chamber, which belongs to the gas-liquid phase Variable (heat pipe) heat transfer type. 2. Use a plane in the heat exchange chamber filled with working fluid to fit the hot end of the thermoe...
