Abstract
The invention discloses a flat-plate solar heat collector and aims to provide a flat-plate solar heat collector which has high heat efficiency and high heat preserving performance. The flat-plate solar heat collector comprises an outer frame, a transparent material plate and a heat insulating layer, wherein the transparent material plate is a transparent plate with a vacuum interlayer; a heat absorbing plate is arranged below the transparent material plate; the heat insulating layer is formed on the inner surface of the outer frame below the heat absorbing plate; and both sides of the outer frame are connected with a water inlet pipe and a water outlet pipe respectively. The transparent material plate has a structure provided with a vacuum layer, so that loss caused on air flow is reduced to zero; and the transparent material plate and the heat absorbing plate on a lower layer are equivalent to vacuum glass with a low-radiation film, so that good heat preserving and heat insulating effects are achieved on a system.
Description
Technical field
The present invention relates to a kind of solar thermal collector, relate in particular to a kind of flat-plate solar heat collector.
Background technology
Plate solar collector is the critical component of solar water heater, and widely used in the market flat plate collector structure is that sunlight sees through on the absorber that transparent material plate shines the black absorption coating, conversion of solar energy is become heat energy after; Conduct heat and give the water in the thermal-arrest passage in the framework; From the structure of present commercially available solar water heater, the heat-proof quality of transparent cover plate is poor, and its inner surface and the heat-absorbent surface temperature difference are big; The radiation heat loss is also big; There is air in inside simultaneously, also can transmit certain heat and cause damage, and these two heat-energy losses can account for more than the twenty percent of integrated radiant emittance.
Summary of the invention
To above-mentioned prior art, it is high that the technical problem that the present invention will solve provides a kind of thermal efficiency, the flat-plate solar heat collector of good heat insulating.
In order to solve the problems of the technologies described above; The present invention adopts following technical scheme: a kind of flat-plate solar heat collector; Comprise outside framework, transparent material plate, heat-insulation layer, said transparent material plate is the transparent panel with vacuum interlayer, and said transparent material plate below is provided with absorber plate; Heat-insulation layer is arranged on the inner surface of the below outside framework of absorber plate, and the both sides of outside framework are connected with water inlet pipe and outlet pipe respectively.
As preferably, the upper surface of said absorber plate is coated with heat absorbing coating.
As preferably, be provided with the vertical heat accumulation dividing plate of several piece between said absorber plate and heat-insulation layer.
Compared with prior art; The present invention has the following advantages: transparent material plate is the structure with vacuum layer; The mobile loss that causes is reduced to zero to air, and the absorber plate of transparent material plate and lower floor is equivalent to the vacuum glass of a band low-radiation film, and system is played good function of heat insulation.
