Background technology
Solar thermal collector is the key equipment of solar water heater, and the popularization of the efficient solar thermal collector of development of new to solar energy heat utilization technology is significant.Ordinary hot tubular type flat-plate solar collector in present China market, structure is simple, cheap, easy to maintenance, but through widely using for many years, has following problems demand to solve: 1. heat collector surface heat waste is large, and collecting efficiency is low; 2. in-tube fouling problem, makes the efficiency of water heater obviously decline; 3. ice formation issues in pipe, in the winter of severe cold, the water in Water heater pipeline build-ups ice, and volume swells, and causes pipeline spalling; 4. inner air tube etching problem.Other novel heat pipe-type flat-plate solar collectors are as comparatively large in high temperature section heat loss in honeycomb heat pipe-type flat-plate solar collector, and hot pipe type vacuum tubular type solar thermal collector load performance is poor, destructible, bombing, easy fouling and be not easy to Integration of building.This is all that the practicality of solar thermal collector brings inconvenience.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of plate solar collector, significantly improves the collecting efficiency of heat collector.
The technical scheme that the utility model is taked is:
A kind of plate solar collector, cover plate relative position is provided with base plate, support is provided with between described cover plate and base plate, described support and cover plate, base plate forms a cavity, header is provided with above cavity, in described cavity, heating plate is installed, the first heat-insulation layer is provided with between described heating plate one side and base plate, described heating plate another side is provided with multiple copper heat pipe 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 fully contacts with runner tube wall, described runner is through header cavity, header cavity internal pore is provided with the second heat-insulation layer, cover plate material is vacuum glass and plates one deck reflectance coating at the one or both sides of 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.
Adopt in described copper heat pipe potassium hydroxide, NaOH, phosphoric acid, water wherein one or more mixtures formed as medium.
Described heating plate scribbles solar selectively absorbing coating.
A kind of plate solar collector that the utility model provides, by adopting above structure, beneficial effect is as follows:
1, cover plate material is vacuum glass or double glazing, heat-insulating property is superior, the infrared reflection film energy reflects infrared light that interior surfaces of glass plates, suppress the convection heat transfer' heat-transfer by convection of heat collector and external environment, conduction heat transfer and radiant heat transfer, improve collecting efficiency, make the most medium passed in copper heat pipe of heat transformed by absorber plate, strengthen the programming rate of water-heater efficiency and raising water;
2, the heat-insulating property scribbling vacuum (or hollow) the glass cover-plate high-quality of reflectance coating makes heat collector be subject to the impact of ambient temperature lower, also normally can work when temperature is lower, and solve the problem that in ordinary hot tubular type flat plate collector pipe, easily fouling is frozen, the easy frosting of glass cover-plate condenses;
3, the absorber plate of this heat collector is connected with many independent copper heat pipes, every root copper heat pipe one-way heat conduction, and thermal resistance is little, and heat conduction is fast;
4, adopt in copper heat pipe potassium hydroxide, NaOH, phosphoric acid, water wherein one or more mixtures formed as medium, its in heat pipe gas-liquid change heat transfer, make the condensation segment output temperature of heat pipe can reach more than 300 DEG C, therefore heat collector has and starts fast, feature rapidly of conducting heat;
5, the technical program structure, technique are simply, be easy to realize, and structure are easy to Integration of building.
