Description

Integrated middle-temp. solar heat collector

The utility model relates to a kind of single flow solar energy heat collector.

Temperature solar heat collecting device in existing, such as the band of operating temperature 〉=90 ℃ focuses on the solar energy heat collector of reflector, specific product adopts single middle temperature heat collecting element mostly.Under the low situation of heating object initial temperature, its collecting efficiency is not high enough and can't utilize diffused light; On the other hand, adopt the heat collector of DC operation mode to have advantages such as response is fast, but then effect is also bad as constant temperature delivery water, even because also can't export high temperature as the low then intensity of illumination of design temperature; Then the working time greatly reduces as the design temperature height.

The purpose of this utility model is that temperature solar heat collecting device in a kind of collecting efficiency height, easy to install, response is fast and cost the is low single flow will be provided.

The purpose of this utility model is achieved in that the various heat collecting elements that operating temperature is different are connected in series successively by the height of operating temperature and makes the integrated form heat collecting element that tubulose heat collecting element for example that focal length is short or the band one-dimensional focusing reflector that volume is less is connected in series the integrated form heat collecting element of making mutually with the coil of pipes plate absorbing body; Be arranged in the heat collector housing and the serial connection automatic temperature control valve comprises accuracy of temperature control error 〉=9 ℃ in the heat collector pipeline fuzzy control valve is made temperature solar heat collector in the integrated form, this heat collector is generally flat box body shape with transparent thermal baffle, integrated form heat collecting element, adiabatic backboard are stacking again.Heat collector is connected by heat carrier with accumulation of heat or heat-exchanging part by input/output port and pipeline and outside.In view of general temperature-sensing valve control accuracy error is no more than 8 ℃, the utility model is taken the temperature-sensing valve of temperature departure 〉=9 ℃ as the fuzzy control valve; Also can dispose external reflector when needing in addition, and comprise the little concentration inverse light panel of one dimension at the upside of heat collector or downside.

Thereby the utility model is connected in series the heat collecting element of different temperatures characteristic and fuzzy control valve and can obtains best of breed and improve collecting efficiency and reduce cost in a heat collector, response speed is also faster, and heat collector adopts external reflector then can increase quantity of heat production.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 and Fig. 2 provide an embodiment of the present utility model.They are respectively that the right side of an integrated solar boiler is looked and partly cutd open and face.The right side is looked partly to cut open along facing median vertical line and is got.

Investigate two parts of the rectangular in-out-snap of thick line in the corresponding diagram 2 respectively.The outer part of frame can be regarded one as with transparent cover plate 2, by the tube plate absorber 3 and the stacking flat box body shape single flow flat plate solar water heater of making in the housing 1 that is arranged in of adiabatic backboard of the dish system of approach shown in the dotted line among Fig. 2, its efficient when the output low-temperature water heating is higher, and cost is also lower; In the frame, arranging three single flow one dimension gathering solar heat collectors that operating temperature is different by horizontal direction parallel.They are made up of through the heat insulation tubulose heat collecting element 6 of body, the tubulose heat collecting element 7 and the one-dimensional focusing reflector 4 of vacuum heat-insulation with individual layer the not heat insulation tubulose heat collecting element 5 of sensitive surface, sensitive surface respectively.The cuing open of Fig. 1 shown the light path (for giving top priority to what is the most important, other content having been done to simplify and tube plate absorber 3 is reduced to a flat board among the figure) the when relative position that provided tubulose

heat collecting element

6,7 and one-dimensional focusing reflector 4 and light-condensing and heat-collecting device are in the operating position.Warm thermal-arrest during these three light-condensing and heat-collecting devices are fit to do in the frame.Next, make the integrated form heat collecting element by shown in dotted line among Fig. 2 and the arrow pipeline of coil of pipes plate absorbing body 3 and three light-condensing and heat-collecting devices being connected successively by the operating temperature height, and one of serial connection is that 100 ± 10 ℃ fuzzy control valve is made full-automatic integrated solar boiler by two respectively have a free end to be heated its setting operating temperatures that the light moulding pipe of bimetal leaf of excurvation makes in the pipeline of integrated form heat collecting element.The back side that temperature-sensing valve can be welded in the temperature highest point in the temperature highest point of tube plate absorber 3 or heat collector water route is non-sensitive surface; Again with the input termination running water of heat collector; Output termination attemperater just becomes full-automatic integrated solar boiler system.During system works, in case heat-collecting temperature is opened temperature-sensing valve, running water just begins to flow.After entering stable state, water is progressively heated through pipeline and is exported; The air preheater of one section tube plate absorber manufacturing of water inlet pipe string of heat collector can effectively increase heat-collecting capacity in the higher occasion of temperature; In addition, can also post luxuriant and rich with fragrance lens in tubulose heat collecting element the place ahead focuses on; Because focusing heat collection element focal length used herein is shorter, thereby insensitive to the variation of sun altitude, so the inclination angle of heat collector can be adjusted once in one to two week.This boiler is put the outer and height of balcony to be put attemperater and just becomes fully-automatic household solar water shower system.

Point out that in passing part also can be regarded temperature solar heat collecting device in the integrated form as in Fig. 2 bold box; The outer part of bold box has then been applied for patent with " integrated solar heat collector " in addition.
