Heat pipe

Material and use principle

heat pipe is in all the glass tube basis, in the vacuum tube inserted a root copper bar, when using, one end of copper bar in contact with water tank heat transfer. Characteristic is no water pipe, the non-furring, resistance to freeze, with super, super fast absorption of heat conduction and long life three advantages.
