The union pipe at tube opening end, the base frame for connecting vacuum tube blind end and the reflecting plate below vacuum tube group, full glass are true
Blank pipe includes outer glass pipe and the inner glass tube being sheathed in outer glass pipe, and vacuum is formed between outer glass pipe and inner glass tube
Layer, inner glass tube is interior to be equipped with partition plate along central axis, U-shaped water route will be separated into inside inner glass tube；Union pipe include shell,
The liner being sheathed in shell, the water inlet pipe being sheathed in liner, form water outlet water route between water inlet pipe and liner；U-shaped water route
Water inlet connection water inlet pipe, the water outlet connection water outlet water route in U-shaped water route.
Further, the outer glass pipe and the inner glass tube are made of low emissivity glass.
Further, the inner glass tube outer wall is equipped with heat absorbing coating.
Further, the heat absorbing coating is alumilite process coating.
Further, the inner wall of the inner glass tube, which is sticked, pressure-bearing inner liner, and the section of pressure-bearing inner liner is arc-shaped structure.
Further, the union pipe further includes the thermal insulation layer being filled between the shell and the liner.
Further, the thermal insulation layer is phenol formaldehyde foam thermal insulation layer, and thickness is 25mm~50mm.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model uses the structure in U-shaped water route, cold water is had during all-glass vacuum tube is flowed out fully
Time carry out heat exchange, while also contribute to hot water and be discharged to during liner not with new stream into all-glass vacuum tube
Cold water mix so that cold water does not have to mix hot water just is inputted liner with hot water in whole workflow, substantially increases system
The thermal efficiency.The solar radiant energy increase being absorbed to using heat absorbing coating, that is, added to obtain heat, improve the thermal efficiency, can be effective
Reduce radiation loss.
2nd, it is made of low emissivity glass, compared to simple glass fractional energy savings higher.Using pressure-bearing inner liner structure, can bear compared with
High pressure, reduces spoilage.There is the operating temperature of higher using phenol formaldehyde foam thermal insulation layer, and it is non-ignitable, there is more preferable insulation
Performance, it is more totally, harmless.
