技术指标
双真空玻璃管中的内管来传输由选择性涂层吸收的热能量密封传递流体。介绍
全玻璃太阳能热管完全由硼硅玻璃3.3。 在一个全玻璃太阳能热管，内管与传导流体在密封抽空以形成外和内管之间的1旁边另一个真空。 这个抽空内管工程作为铜管传递热能。
工作原理
选择性涂层吸收太阳能来加热被密封在所述内管的传递流体。 转移流体蒸发和蒸气中声速的冷凝器的管，在那里它热能传送到水的顶部上升。 蒸汽凝结和回流。 这种循环将继续，只要有太阳能。
优势
（1）.Superior热conductivityIt可以传输更多的热能，甚至比银，铜或铝，其具有非常高的热导率。
（2）等温.Superior稳定性：几乎没有压降，以及在该内管的温度降低。
（3）在所述内管的热流.The密度可以通过修改冷凝器或蒸发部的加热表面被改变。
（4）。 它可以在两个加压和不加压的系统中。
（5）。 热水在水箱热能不会通过冷凝器失去当管停止吸收太阳能，因为这里在该内管的真空度。
（6）。 该管被防冻剂为有在管没有水。

Specifications
dual-vacuum glass tube with transfer fluid sealed in the inner tube to transfer the heat energy absorbed by selective coating.Introduction
All-glass solar heat pipe is entirely made of borosilicate glass 3.3. In an all-glass solar heat pipe, the inner tube with transfer fluid sealed in is evacuated to form another vacuum beside the one between the outer and the inner tubes. This evacuated inner tube works as a copper pipe to transfer heat energy.
Working principle
The selective coating absorbs solar energy to heat up the transfer fluid that is sealed in the inner tube. The transfer fluid evaporates and the vapor rises up in sound velocity to the Condenser at the top of the tube, where it transfers heat energy to the water. The vapor condenses and flows back. This circulation will continue as long as there is solar energy.
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.
