Description
Technical field
The utility model relates to a kind of solar energy heat collection pipe and solar thermal collector.
Background technology
Existing U type pipe heat collector adopts aluminum fin to conduct heat between U type pipe and vacuum tube, because aluminum fin is very not tight with contacting of U type pipe and vacuum tube inwall, thereby heat-transfer effect is poor, thereby the thermal efficiency that has influence on heat collector is not very high.
The utility model content
The utility model provides a kind of solar energy heat collection pipe, is used for solar thermal collector, and heat-transfer effect is good.
The utility model also provides a kind of solar thermal collector, the collecting efficiency height.
Described solar energy heat collection pipe comprises the all-glass vacuum thermal-collecting tube of lower end sealing, be provided with sleeve pipe in the all-glass vacuum thermal-collecting tube, pipe and outer tube in sleeve pipe comprises, wherein interior pipe both ends open, outer tube is the finned tube of lower end sealing, between finned tube and the all-glass vacuum thermal-collecting tube movingly.
Described solar thermal collector, comprise solar energy heat collection pipe, water inlet pipe, outlet pipe, solar energy heat collection pipe is connected in parallel between water inlet pipe and the outlet pipe, and solar energy heat collection pipe comprises the all-glass vacuum thermal-collecting tube of lower end sealing, is provided with sleeve pipe in the all-glass vacuum thermal-collecting tube, pipe and outer tube in sleeve pipe comprises, pipe both ends open wherein, outer tube is the composite fin tube of lower end sealing, between finned tube and the all-glass vacuum thermal-collecting tube movingly, interior pipe is communicated with water inlet pipe, and outer tube is communicated with outlet pipe.
Described finned tube is preferably the finned tube that copper aluminium is compound or stainless steel aluminium is compound, and the inboard of pipe is copper or stainless steel, and the outside is the fin that aluminium and aluminium push out.
As preferred version, interior pipe and outer coaxial tube setting.
As another kind of preferred version, the coaxial setting of water inlet pipe and outlet pipe, and the sealing of the homogeneous end opening other end.All are connected in parallel on solar energy heat collection pipe between water inlet pipe and the outlet pipe and are with journey and connect.
The utility model is because to have adopted sleeve structure, outer tube be finned tube, symmetrical configuration, and outer tube and all-glass vacuum thermal-collecting tube are movingly, and heat conductivility is preferably arranged; Adopt the finned tube that copper aluminium is compound or stainless steel aluminium is compound, owing to adopted the multiple tube technology, thereby both are in conjunction with very tight, heat-transfer effect is good.Aluminum pipe is through extruding, and forming is with it numerous fins of one, increased greatly with vacuum tube in the heat exchange area of hot-air.
In a word, the utlity model has advantage simple in structure, novel, that heat-transfer effect is good, collecting efficiency is high.
