Content of the invention
For solving above-mentioned technical problem, the present invention provides a kind of plate solar collector, significantly improves the collecting efficiency of heat collector.
The technical scheme that the present invention takes is:
A kind of plate solar collector, cover plate relative position is provided with base plate, it is provided with support between described cover plate and base plate, described support and cover plate, base plate constitutes a cavity, it is provided with header above cavity, in described cavity, heating plate is installed, it is provided with the first heat-insulation layer between described heating plate one side and base plate, described heating plate another side is provided with multiple copper heat pipes arranged side by side, the evaporator section of described copper heat pipe is connected with heating plate, the condensation segment of copper heat pipe is arranged in header, the condensation segment of copper heat pipe is fully contacted with runner tube wall, described runner passes through header cavity, header cavity internal pore is provided with the second heat-insulation layer, cover plate material is vacuum glass the one or both sides plating last layer reflectance coating in vacuum glass inner surface.
The reflectance coating of described cover-plate glass inner surface plating is infrared reflection film.
Described cover plate material is vacuum glass or double glazing.
Using potassium hydroxide, sodium hydroxide, the mixture of phosphoric acid, water one of which or several composition as medium in described copper heat pipe.
Solar selectively absorbing coating is scribbled in described heating plate.
A kind of plate solar collector that the present invention provides, by using above structure, having the beneficial effect that:
1st, cover plate material is vacuum glass or double glazing, heat-insulating property is superior, the infrared reflection film that interior surfaces of glass plates can reflect infrared light, the convection heat transfer' heat-transfer by convection of suppression heat collector and external environment, conduction heat transfer and radiant heat transfer, improve collecting efficiency, the heat overwhelming majority converting by absorber plate is made to pass to the medium in copper heat pipe, the programming rate strengthening water-heater efficiency and improving water；
2nd, scribbling the heat-insulating property of vacuum (or hollow) the glass cover-plate high-quality of reflectance coating, so that heat collector is affected by ambient temperature relatively low, in the case that temperature is relatively low also can normal work, and solve the problems, such as easy fouling icing in ordinary hot tubular type flat plate collector pipe, glass cover-plate easy frosting condensation；
3rd, the absorber plate of this heat collector is connected with many independent copper heat pipes, every copper heat pipe one-way heat conduction, and thermal resistance is little, and heat conduction is fast；
4th, potassium hydroxide, sodium hydroxide, the mixture of phosphoric acid, water one of which or several composition are adopted in copper heat pipe as medium, its gas-liquid change heat transfer in heat pipe, make the condensation segment output temperature of heat pipe can reach more than 300 DEG C, therefore heat collector has that startup is fast, rapid feature of conducting heat；
5th, the technical program structure, process is simple, it is easy to accomplish, and structure is easy to Integration of building.
