Background technology
The flat-plate solar heat collector that at present domestic a large amount of productions are used belongs to low form mostly, is mainly used in domestic hot water's supply, is difficult to satisfy the more extensive use of solar thermal utilization.The flat plate collector that is used for low temperature has only one deck cover plate, and glass cover-plate is closer apart from the plate core, causes heat loss easily.In order to improve the collecting efficiency of flat plate collector, some main losses need to reduce, and these losses can be divided into optical loss and heat loss.
Usually heat loss at high temperature can increase sharply, and light loss is a constant.For middle warm type water heater, heat loss is bigger to the influence of collecting efficiency.And caused by convection current in the positive main heat loss of heat collector.Circulating air between cover plate and the plate core arrives cover plate with the heat delivery of plate core.Because air is flowed through heat collector everywhere, so convection losses again can take place by after the heat conduction in heat.The transfer of heat of the plate wicking being received by a plurality of links such as convection current, infra-red radiation, heat conduction, emissions arrives environment, the infrared emittance of coating for selective absorption can reach and be adjusted downward to 5% like this, the heat loss of existing flat plate collector is still than higher comparatively speaking, how to reduce the heat loss of existing flat-plate solar collector, the collecting efficiency that improves heat collector becomes the problem that present flat-plate solar collector need solve.
The utility model content
Technical problem to be solved in the utility model has provided a kind of middle warm type flat-plate solar collector, this utility model has overcome the technological deficiency of existing product, greatly reduce the heat loss amount of temperature when higher, improve the collecting efficiency of heat collector, guaranteed the high efficiency of middle warm type flat-plate solar collector thermal-arrest.
For solving the problems of the technologies described above, warm type flat-plate solar collector during the utility model is a kind of, it is characterized in that, comprise the allotype aluminum alloy framework, the top of described allotype aluminum alloy framework is covered with inside and outside two-layer cover plate, two-layer cover plate is respectively inner cover plate and outer cover plate, described inner cover plate is fixedly arranged in the draw-in groove of allotype aluminum alloy frame inner wall setting, be equipped with heat-insulation layer in the sidewall of described allotype aluminum alloy framework and the bottom thereof, the heat-insulation layer top of described bottom is evenly equipped with some runners, the top of described runner is provided with absorber plate, and the surface of absorber plate is coated with one deck coating for selective absorption, and absorber plate is welded in the top of runner; Back side Ω shape aluminium strip parcel is adopted at the back of described each runner, and the both sides of each back side Ω shape aluminium strip are welded in the bottom of absorber plate.
The material of described outer cover plate is low iron tempering ultra-clear glasses, and the thickness of outer cover plate is 2.5mm~4mm, and described inner cap material is perfluoroethylene-propylene, and inner cover plate thickness is 0.5mm~1mm.
The bottom of described inner cover plate is provided with some muscle, and described muscle is distributed in the bottom of inner cover plate, and play muscle and be spaced apart 200mm, highly be 1mm~5mm.
The material of described heat-insulation layer is phenol formaldehyde foam, and the thickness of heat-insulation layer is 50mm~70mm, and described heat-insulation layer covers one deck aluminium foil outward, and the thickness of aluminium foil is 0.01mm~0.1mm.
The beneficial effects of the utility model are: the warm type flat-plate solar collector adopts double-canopy plate form in the utility model under the constant situation of plate solar collector area, and effect of heat insulation improves, and has improved the collecting efficiency of heat collector greatly.In addition, the aluminium foil that heat-insulation layer covers outward can reduce the heat loss of heat radiation form, and Ω shape aluminium strip parcel is adopted at the runner back side, has improved heat output.This architecture advances has lowered the heat loss amount when temperature is higher greatly, the high efficiency of warm type heat collector in the assurance.
