Specification of solar heat pipe:
Super conductive vacuum tube is based on the all-glass vacuum tube, then a copper bar put into it, When using, the end of of copper bar contact with water in tank and conduct heat, It's characteristics is no water inside, non-furring scale, anti-freezing. And with super heat, super fast thermal conductivity and long life of three advantages.
