Accompanying drawing explanation
Fig. 1 is the structural representation of new type solar energy high-efficient flat-plate heat collector of the present utility model.
Shown in figure: 1-glass cover-plate; 2-thermal isolation film; 3-absorber plate; 4-housing; 5-adiabator layer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of new type solar energy high-efficient flat-plate heat collector of the present utility model, comprise housing 4, be arranged on absorber plate 3 in housing 4 and adiabator layer 5, be arranged on glass cover-plate 1 above absorber plate 3, wherein, between absorber plate 3 and glass cover-plate 1, be provided with thermal isolation film 2, thermal isolation film 2 is fixedly installed on housing 4.
In the above-described embodiments, for strengthening stability and the heat insulation effect of thermal isolation film, contactless between described thermal isolation film 2 and adiabator layer 5, remain with space; For fully ensureing the thermal loss realizing efficient minimizing heat collector and the collecting efficiency improving flat plate collector, the distance between described thermal isolation film 2 and absorber plate 3 is preferably made to be greater than distance between thermal isolation film 2 and glass cover-plate 1 when arranging, described thermal isolation film 2 is preferably transparent heat-insulating film, make to form the first incubation cavity between thermal isolation film 2 and glass cover-plate 1, form the second incubation cavity between thermal isolation film 2 and absorber plate 3, described second incubation cavity communicates with the space between thermal isolation film 2 and adiabator layer 5; Preferably, the aspect ratio between described first incubation cavity and the second incubation cavity is 1:3.
In the above-described embodiments, for fully ensureing the thermal loss realizing efficient minimizing heat collector and the collecting efficiency improving flat plate collector, described thermal isolation film 2 adopt colourless, transparent, do not absorb water, airtight, high temperature resistant, the anti-aging and thermal isolation film of long service life, be preferably polyfluorinated ethylene propylene (FEP) plastic foil, its refractive index is 1.338, and light transmittance is 93%-95%; Preferably, the thickness of described thermal isolation film 2 is 0.025mm ~ 0.03mm, FEP (polyfluorinated ethylene propylene) plastics wherein, thickness 0.025 ~ 0.03mm; Described thermal isolation film 2 is same with the area equation of glass cover-plate 1, is fixed on housing 4 by thermal isolation film 2 being evened up the rear pressing of tension.
