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.
