Semiconductor refrigeration equipment achieving heat radiation through heat pipes

Abstract

Semiconductor refrigeration equipment achieving heat radiation through heat pipes comprises a system power supply, a temperature control system, a heat radiation system, a reaction tank and a magnetic stirring system. A reaction trough is arranged on the innermost side of the reaction tank, a thin copper layer is arranged outside the reaction tank, semiconductor chilling plates are closely attached to the outer side of the thin copper layer, and a heat insulation layer is arranged on the outer sides of the semiconductor chilling plates, and wrapped by an aluminum alloy shell. The temperature control system comprises a temperature control instrument, a temperature sensing probe, a control single plate, the semiconductor chilling plates and a semiconductor chilling plate power source, the temperature control instrument can be used for displaying and setting the temperature of the reaction trough, and the control single plate is responsible for coordinating various kinds of work. The heat radiation system comprises the heat pipes, cooling fins and a fan. The heat delivery surfaces of the semiconductor chilling plates are surrounded by the heat pipes, heat generated by the heat delivery surfaces is constantly led out of the heat pipes, and it is ensured that the semiconductor chilling plates work normally. A magnetic rotor is arranged at the bottom of the reaction trough, a magnetic stirrer drives the rotor to rotate, and the magnetic stirring system is formed. The system power supply supplies power to the whole system.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a semiconductor refrigeration device with a heat pipe for heat dissipation. Background technique [0002] In scientific research work, due to the needs of experiments, some processes of some products are required to be carried out under low temperature conditions. Due to the limitation of refrigeration equipment, the current low temperature reaction device occupies a large space, the operation is also relatively cumbersome, and there are problems with temperature control. Accuracy and many other issues. [0003] Semiconductor refrigeration is a refrigeration method that uses the thermoelectric effect to achieve refrigeration. This refrigeration method has no mechanical transmission parts, works without noise, does not require refrigeration fluids, and is small in size and light in weight. It is very suitable for use in laboratories. However, traditional semiconductor refrigeration e...
