Vacuum Pump for Heat Pipe
Fluid medium inside the heat pipe:
Very low temperature (- 273-70 ℃) helium, argon, krypton, nitrogen, methane
Low temperature (- 70 ~ 200 ℃) freon, ammonia, acetone, methanol, ethanol, heptane, water
Naphthalene, dowtherm, THERMEX, sulfur and mercury at medium temperature (200-500 ℃)
Cesium, rubidium, potassium and sodium at high temperature (500-1000 ℃)
Extremely high temperature (> 1000 ℃) lithium, calcium, lead, indium, silver
Heat pipe pump:
The key part of the heat pipe production process is vacuum packaging. At present, most of the pumps used in the domestic heat pipe production degassing platform are oil rotary vane vacuum pumps with roots pumps. Although the price of this pump set is low, the use process and cost are high, and the oil products need to be changed frequently, which has a great impact on the service life of the pump. Therefore, it is not recommended.
The best vacuum pump for the heat pipe is dry screw vacuum pump. In view of the large amount of water vapor and other special liquids in the production process of the heat pipe, the dry screw vacuum pump has strong water vapor resistance and corrosion resistance and low
