Description
Technical field
The utility model relates to a kind of U type thermal-collecting tube and solar thermal collector.
Background technology
Existing U type thermal-collecting tube adopts aluminum fin to conduct heat between U type pipe and all-glass vacuum thermal-collecting tube, because aluminum fin is very not tight with contacting of U type pipe and all-glass vacuum thermal-collecting tube inwall, thereby heat-transfer effect is poor, thereby the thermal efficiency that has influence on U type thermal-collecting tube is not very high.
The utility model content
The utility model provides a kind of U type thermal-collecting tube, and heat-transfer effect is good, thermal efficiency height.
The utility model also provides a kind of solar thermal collector, thermal efficiency height.
Described U type thermal-collecting tube comprises the all-glass vacuum thermal-collecting tube of lower end sealing, be provided with heat conductive bar in the all-glass vacuum thermal-collecting tube, be provided with port U type pipe up in the heat conductive bar, U type pipe both ends open, the heat conductive bar outside is distributed with fin, between fin and the all-glass vacuum thermal-collecting tube movingly.
Described solar thermal collector, comprise U type thermal-collecting tube, water inlet pipe, outlet pipe, U type thermal-collecting tube is connected in parallel between water inlet pipe and the outlet pipe, U type thermal-collecting tube comprises the all-glass vacuum thermal-collecting tube of lower end sealing, be provided with heat conductive bar in the all-glass vacuum thermal-collecting tube, be provided with port U type pipe up in the heat conductive bar, U type pipe both ends open, the heat conductive bar outside is distributed with fin, between fin and the all-glass vacuum thermal-collecting tube movingly.
As preferred version of the present utility model, heat conductive bar is an aluminium, and fin is formed by heat conductive bar extruding back.
U type pipe can adopt copper pipe or stainless steel tube, guarantees to contact with water for a long time, and is not perishable.
As preferred version further, heat conductive bar is an aluminium, and U type pipe adopts copper pipe or stainless steel tube, and compound with heat conductive bar is one.
The utility model symmetrical configuration, the heat conductive bar outside are distributed with fin, fin and all-glass vacuum thermal-collecting tube movingly, not only increased greatly with vacuum tube in the heat exchange area of hot-air, and contact well has heat conductivility preferably; It is one that U type pipe and heat conductive bar have adopted the multiple tube technology compound, thereby both are in conjunction with very tight, and heat-transfer effect is good; Heat conductive bar is through extruding, and forming is with it numerous fins of one, and heat transfer property is good.
In a word, the utlity model has advantage simple in structure, novel, that making is easy, heat-transfer effect is good, collecting efficiency is high.
