Abstract
The invention discloses an idle-sunning resistant flat-plate solar collector. The idle-sunning resistant flat-plate solar collector comprises an automatic light shading and heat insulating transparent cover plate, a solar absorber plate core, a heat-insulating back panel and a component frame, wherein a layer of temperature-sensitive phase-change dimming material or liquid crystal dimming film is compounded on the surface of the automatic light shading and heat insulating transparent cover plate. The invention has the following technical effects: when the interior of the flat-plate collector reaches a certain temperature due to idle sunning, the temperature-sensitive phase-change dimming material on the surface of the glass is subject to phase change, the transmission of the cover plate of the collector is changed, and the transparent state is switched to a light-tight sate, so that an automatic light shading function is performed, the solar absorber plate core is prevented from continuous heat absorption which results in temperature rise, accordingly, idle sunning is avoided, and the service life of the product is prolonged; and when the collector decreases to a certain temperature, the solar radiation transmission of the cover plate of the collector is changed, the light-tight state is switched to the transparent state, and the normal working state recovers.
Description
Technical field
The present invention relates to a kind of flat-plate solar collector.
Background technology
In the solar water heating system installation process, before system's filling heat-conductive medium, flat-plate solar collector is exposed under the sunlight inevitably, because pipeline is not connected heat-conducting medium, the heat collector internal heat can't pass out heat collector, heat collector forms air drying, cause the collector plate core temperature to raise, when summer, can reach 150 ℃ ~ 200 ℃, cause easily warming plate temperature distortion, carbonization, the heat absorbing sheet oxidation stain has a strong impact on properties of product and service life; In the product use procedure, since heat-conducting medium does not flow for a long time or heat conduction is smooth and other extreme cases under, make heat collector be in easily the air drying state, air drying breaks away from heat absorbing coating and plate core base material, accelerated the aging of material, thus photo-thermal conversion efficiency and the service life of having reduced heat collector.At present, flat-plate solar collector does not have the function of the anti-air drying of automatic shading.
Summary of the invention
The purpose of this invention is to provide a kind of anti-air drying flat-plate solar collector.
Technical scheme of the present invention is, a kind of anti-air drying flat-plate solar collector, comprise automatic shading and heat-insulation transparent cover plate, solar absorber plate core, insulation backboard, module frame, at surface recombination one deck temperature-sensitive phase transformation light control material or the liquid crystal light modulation film of automatic shading heat-insulation transparent cover plate.
Described automatic shading heat-insulation transparent cover plate is vacuum glass.
Vacuum glass is made of the doubling glass that the common safety glass of a slice and a slice have the temperature-control discoloring function.
Described liquid crystal light modulation film is comprised of ITO film and liquid crystal composite material.
The present invention has following technique effect, when flat plate collector reaches uniform temperature because of air drying inside, the temperature-sensitive phase transformation light control material that is positioned at glass surface undergoes phase transition, change the transmitance of collector cover plate, become light tight state by pellucidity, thereby realize the effect of automatic shading, stop the solar absorber plate core to continue heat absorption and the rising temperature, thereby avoid air drying, prolong the service life of product.When heat collector drops to uniform temperature, can change the transmitance of collector cover plate solar radiation, by the light tight pellucidity that becomes, recover normal operating conditions.
