All glass heat pipe solar vacuum tube

Advantages

(1).Superior thermal conductivityIt can transfer much more heat energy even than silver, copper or aluminum which has very high heat conductivity.

(2).Superior isothermal stability: There is little pressure drop as well as temperature drop in the inner tube.

(3).The density of heat flow in the inner tube can be changed by modifying the heating surface of the condenser or the evaporation part.

(4). It can be used in both pressurized and unpressurized systems.

(5). Heat energy of the hot water in the tank will not lose through the condenser when the tube stops absorbing solar energy as there is a vacuum in the inner tube.

(6). The tube is anti-freezing for there is no water in the tube.
