The present invention proposes a semiconductor constant temperature device with dual temperature zones, which is composed of a semiconductor refrigeration device, a liquid cooling plate, a regenerator, a temperature difference driven proportional regulating valve, a liquid storage device, and a liquid cooling radiator. The two temperature zones are completed using the same heat dissipation device. It meets the needs of temperature control and constant temperature in two temperature zones. It is easy to arrange, saves volume, and is flexible and convenient. By setting up a regenerator, heat can be exchanged effectively and the temperature can be evened. Especially when the two temperature zones are cooled and heated separately, the heat recovery can be compensated. , to achieve energy saving; the temperature difference drives the proportional regulating valve to connect the liquid receiver and the liquid-cooled radiator respectively, adjust the flow ratio of the coolant flowing to the liquid receiver and the liquid-cooled radiator, and adapt to different heat dissipation load changes. Larger heat dissipation loads can be passed through The liquid cooling radiator effectively dissipates heat; liquid cooling is adopted, with strong heat transfer capacity, low noise, and small size; the system can be used in electronic equipment, scientific instruments, etc.
Description
Technical field [0001] The invention relates to a semiconductor constant temperature device, in particular to a dual temperature zone semiconductor constant temperature device. Background technique [0002] The working principle of semiconductor refrigeration devices is based on the Peltier effect, which was first discovered by JAC Peltier in 1834. Because of its strong flexibility, simplicity and convenience, and easy switching between cold and heat, it is very suitable for the field of miniature refrigeration. Places with special requirements. Multiple temperature zones are separately controlled to meet different temperature requirements. The temperature of each temperature zone can be set according to requirements, and the temperature of each temperature zone can be adjusted arbitrarily. If different temperature zones can be used as cold and heat compensation for each other, energy saving can be realized. [0003] The efficiency of semiconductor refrigeration is low, and ordina...
