The heat pipe is a component that can quickly solve the single-point heating issue. It has been designed using the vapor phase, the liquid two-phase change of the material and the principle of convection. Properly speaking, the heat pipe can only be regarded as a part of the heat dissipation device, and it is a heat conduction element instead of a heat dissipation element. Its fast heat-balancing characteristics make its application range and penetration rate quite wide and high.
