The heat pipe is an artificial component with excellent heat transfer performance, composed of a closed metal pipe and an internal working medium. Usually, a support piece is installed outside the heat pipe to increase the heat exchange area and heat exchange amount.
The principle of heat pipe work is as shown. The inside of the heat pipe is filled with a working medium under vacuum. The working medium is saturated inside the heat pipe. There is cold air flowing outside the high end of the heat pipe, and hot air flows outside the low end. The liquid working medium accumulates at the low end of the heat pipe due to gravity. When the hot air flows through the low end, the internal working medium is heated, and the liquid working medium is evaporated by heat to form steam. Because the high-end external cold air flows, the high-end internal saturation pressure is low, and the steam flows to the high-end; meanwhile, the cold air flows through At the high end, the heat pipe is cooled, and the steam in the high end is cooled and then condensed into a liquid state. Then, due to the action of gravity, the liquid working fluid flows along the inner wall of the heat pipe to the low end, and once again is heated to become steam, and the process continues to circulate, and the process continues. Pass the low end heat to the high end. Since the heat exchange inside the heat pipe is mass transfer heat transfer in the phase change mode, the internal heat transfer resistance is extremely low, and the heat transfer efficiency of the whole component is very high after the outer set of the support piece, which greatly saves the power consumption of the device, and can be used for one year. Save 10,000 kWh of electricity for industrial use.
