    Heat pipe composition:

    1. Copper heat pipe
    2. Silicone gasket
    3. Aluminum fin
    4. Vacuum tube

    Working principle

    1. Inside the heat pipe is a vacuum closed cavity of 1.3*(10-1~10-4)Pa, and filled with working liquid
    2. When one side is heated, the liquid evaporates in the core, the steam flows to the other side under low pressure and emits heat which condenses to liquid, and the liquid flows to evaporative side be capillarity along the porous material. 

    This endless cycle allows the heat to be transferred from one side to the other side.
