「Heat Pipe」

Heat pipe is a highly efficient passive thermal conductor. Due to phase transition theory and capillary action, their thermal conductivity is improved by several orders of magnitude compared to pure copper of the same material.

「Principle of Heat Pipes」

After filling the copper core structure with the working fluid inside, the internal pressure is reduced to a negative value and then sealed. One side is the evaporator (heating side), and the other side is the condenser. The liquid between the capillary cores evaporates on the heating side when it starts working, and then the water vapor is driven by a slight pressure from the evaporator towards the condenser. The vapor condenses into water, releasing heat, and the liquid flows towards the evaporator side under capillary action along the copper core. So, the cycle continues, achieving the effect of heat conduction.
