The said U shaped heat accumulating pipe is clamped between the heat absorbing fin and vacuum pipe. The inner side of U shaped heat accumulating pipe attaches to the heat absorbing fin. The outer side of it attaches to the inner wall of vacuum pipe. This invention starts rapidly. It is able to endure freezing and has high heat transfer efficiency. This invention is also simple and convenient.
Description
(1) technical field
The present invention relates to the utilization of solar energy, particularly a kind of solar thermal collector.
(2) background technology
Existing solar heating engineering mostly is header formula all-glass solar vacuum tubular collector with heat collector, header is a cavity bypass structure, all-glass vacuum tube is inserted in monolateral or both sides, seal by the silica gel circle between glass-vacuum tube and the header, be full of water in the vacuum tube, the heat transfer process of system produces convection current by vacuum tube internal water self temperature difference and finishes; Household solar water heater, structure then are vacuum tube and the direct UNICOM of water tank, and by silica gel circle sealing, both shortcomings all are to have the vacuum tube water that breaks to flow out between all-glass vacuum tube and the water tank, cause the whole collecting system can't operate as normal; And the silica gel circle is not withstand voltage yet, leaks easily; Heat exchange efficiency is low.
After this a kind of metal super heat-conductive pipe vacuum tube collector has appearred, heat pipe all is set in each vacuum tube, respectively heat pipe is taken again and put in header the grooved recess that is provided with on female pipe or the household solar water heater storage tank inner bag water in mother's pipe or the storage tank is conducted heat, even this mode has guaranteed that vacuum tube breaks, do not influence the operate as normal of system yet, but one side metal tube and glass tube sealing technology complexity, owing to just conduct heat by the small size contact of grooved recess, heat transfer efficiency is low in addition.
For addressing the above problem, existing U type pipe vacuum collector adopts metal tab to increase heat exchange area, improve heat exchange efficiency, metal tab is generally semi arch or circular arc, contact is outer wall tangent line contact mutually between U type pipe and the fin, but contact area is still limited, and heat exchange efficiency is whole to be improved seldom; Secondly need welding to connect complex process between U type pipe and the fin.
(3) summary of the invention
The object of the present invention is to provide a kind of solar thermal collector, the heat exchange efficiency height, simple in structure, manufacturing process is simple.
The technical solution used in the present invention is as follows:
Solar thermal collector, comprise heat absorption fin, U type thermal-collecting tube in the header, vacuum tube, vacuum tube, described heat absorption fin cross section by two symmetrical camber lines of fitting with the vacuum tube inwall and with two closed curves that symmetrical camber line is formed of the inboard applying of U type pipe; Described U type thermal-collecting tube is installed between heat absorption fin and vacuum tube, fits with the heat absorption fin in the inboard of U type thermal-collecting tube, and the outside and vacuum tube inner tubal wall are fitted.
Heat absorption has the inboard and the vacuum tube inwall of two arcs and U type thermal-collecting tube to be close to respectively after fin adopts this structure, and U type pipe also with the applying of vacuum tube inner tubal wall, whole contact area is big, thermal resistance is little, the heat transfer efficiency height.Absorbing heat in addition need not welding between fin and U type pipe, only U type pipe clamp need be contained in heat absorption fin and the vacuum tube to get final product, easy for installation, also is convenient to make, and the heat absorption fin only needs compression molding to get final product.Preferably, the cross section of heat absorption fin adopts dumbbell shape, and the symmetrical camber line at dumbbell both ends and vacuum tube inwall are fitted; The camber line and the U type pipe inboard at place fit in the middle of the dumbbell.
Further, described header inner cold water inlet pipe and hot water out pipe are provided with respectively; Described U type thermal-collecting tube is imported and exported and is linked to each other with hot water out pipe with the cold water inlet pipe respectively.
Cold water inlet pipe and hot water out pipe one end seal, and the heat transfer process of water in thermal-collecting tube and in the header is one-way flow, the heat exchange efficiency height.Cold water enters in the header, flows into U type thermal-collecting tube with shortest path, under the heat effect of heat absorption fin, flows into hot water out pipe after the water heating.System starts fast, the anti-damage of freezing, heat exchange efficiency height.Do not leak water in the vacuum tube in addition, solved fouling, the bombing problem of vacuum tube, both improved bearing capacity, reduced radiation loss again, can annually use continuously.
Wherein, described heat absorption fin and U type thermal-collecting tube all can adopt copper material to make.
Further, be filled with insulation material between header inside and hot and cold water pipe, preferably adopt the polyurethane integral foaming thermal-insulating to carry out totally-enclosed reinforcement insulation, effectively reduce radiation loss, further improve hot property.
The present invention has following advantage generally with respect to prior art:
System starts fast, pressure-bearing, the anti-damage of freezing, heat exchange efficiency height; Simple in structure, be convenient to make and install.

(5) specific embodiment:
Below with specific embodiment technical scheme of the present invention is described, but protection scope of the present invention is not limited thereto:
Solar thermal collector, comprise heat absorption fin 2, U type thermal-collecting tube 3 in header 6, vacuum tube 1, the vacuum tube, described heat absorption fin cross section is by two symmetrical camber lines of fitting with the vacuum tube inwall and the closed curve dumb-bell shape of forming with inboard two the symmetrical camber lines of fitting of U type pipe, described U type thermal-collecting tube is installed between heat absorption fin and vacuum tube, fit with the heat absorption fin in the inboard of U type thermal-collecting tube, the outside and vacuum tube inner tubal wall are fitted.
Header inner cold water inlet pipe 7 and hot water out pipe 4 are provided with respectively, and U type thermal-collecting tube is imported and exported and linked to each other with hot water out pipe with the cold water inlet pipe respectively.Adopt the 5 totally-enclosed reinforcements insulations of polyurethane integral foaming thermal-insulating between header inside and hot and cold water pipe.
During use, cold water enters in the header, flow into U type thermal-collecting tube with shortest path, the U type thermal-collecting tube inboard that heat can pass to rapidly equally and the heat absorption fin is fitted that heat absorption fin and vacuum tube are fitted and obtained, U type pipe also obtains the heat that the vacuum tube inwall transmits simultaneously, cold water is heated the back and flows into hot water out pipe, and is collected to heat storage water tank, uses for the user.
