Abstract
The invention provides a plastic slab heat collector, relating to the field of solar heat collectors. High cost and inconvenient installation of the solar heat collector used as the core part for the development and utilization of the solar energy become a barrier which blocks the generalization of the solar energy utilization; furthermore, the existing plastic slab heat collector has the problem that the heat conversion efficiency is not sufficiently improved. In order to overcome the problems, the invention provides the plastic slab solar heat collector which has simple structure and light weight; by adopting a technique that an internal wall is coated by a solar absorbing layer, the plastic slab heat collector consists of a plastic slab heat collector frame, a plastic slab heat collector shell, a plastic collecting pipe, a plastic row-pipe heat absorbing plate, a light heat-preservation layer and a plastic hollow transparent cover plate, has simple structure, low manufacture cost and light whole weight, can be arranged on the roofs and balconies and walls exposed to the sun, and can be generalized in the urban in large areas.
Description
Affiliated field;
The present invention relates to field of solar collectors, especially a kind of simple in structure, lightweight plastic board solar thermal collector.
Background technology;
At present, the renewable sources of energy have been included national medium-term and long-term development plan in, and wherein the development and use of family expenses solar thermal energy also more and more come into one's own.As the core component of family expenses solar thermal energy development and use, the expensive and installation of solar thermal collector is inconvenient, has become and has hindered the obstacle that solar thermal utilization is popularized.Existing solar thermal collector is divided into thermal-collecting tube type, flat by shape.Existing its single tube thermal efficiency height of thermal-collecting tube type heat collector, but multitube whole heavy, inconvenience is installed, cost of manufacture is high, can only adapt to the roof and install, and can not overmatter, its total daylighting area is not as flat plate collector.Existing flat plate collector adopts glass cover-plate mostly, the metal absorber plate, though can with the water tank partial installation, whole heavy, the cost height.And existing plastic flat-plate heat collector technology be adopt outer wall to be coated with its heat conversion of solar absorbing layer to be subjected to the plastics poor heat conductivity to influence efficient low, be exactly that its thermal conversion efficiency that adopts outer wall to be coated with solar absorbing layer can not get abundant raising as a kind of pressure-bearing type plastic hollow thin-walled grate solar water heater as described in the patent No. 03284426.3.Also have the patent application 200710167737.2 and 200710126706.2 that proposes before me also to have the problems referred to above.
Summary of the invention;
In order to overcome solar thermal collector, whole heavy, be only limited to the roof is installed, cost of manufacture the is high problem and the problem of existing plastic flat-plate heat collector poor heat conductivity, the invention provides a kind of simple in structure, lightweight plastic board solar thermal collector.
The technical solution used in the present invention is to have adopted plastic flat-plate heat collector housing, plastic flat-plate heat collector shell, plastics manifold trunk, plastics comb absorber plate, heat-insulation layer, plastic hollow transparent cover plate to be assembled into plastic flat-plate heat collector.Plastics comb absorber plate be by clear hollow and in but the plastic plate of many little combs of water flowing is arranged, float inside pipe wall daylighting face is coated solar selectively absorbing coating and is made.On the plastics manifold trunk, have and use the link slot that is communicated with the comb absorber plate.Plastics comb absorber plate inserts in the plastics manifold trunk link slot and adopts the Plastic Welding mode to connect.
The invention has the beneficial effects as follows that simple in structure, manufacturing cost reduces greatly, overall weight alleviates greatly, solar energy absorbing coating is at plastics comb absorber plate inwall, directly contact with water.Solved the problem of solar energy absorbing coating, improved thermal conversion efficiency and can well utilize the plastics poor thermal conductivity to improve heat insulation and preservation effect again in outer wall plastics absorber plate heat conductivility difference.Can also be installed in balcony, wall on the sunny side the roof except installing.Installation Flexibility is stronger, but can popularize in the city large tracts of land.

The specific embodiment;
First-selected make the plastic flat-plate heat collector shell 8 of similar square box shape by injection mo(u)lding, also can plastic material be assembled into plastic flat-plate heat collector shell 8 by adhesion, the inside filling light thermal insulation material is formed heat-insulation layer 7.The plastics that adopt transparent and water-fast, heatproof, good weatherability by extrusion molding make hollow and in but the transparent plastic sheet material of many water flowing float pipes 2 is arranged, coating solar selectively absorbing coating 10 at float inside pipe wall daylighting face just becomes plastics comb absorber plate 6.Adopt heatproof, water-fast, good weatherability plastic pipe as manifold trunk 3, with the Plastic cap 4 hot melt shutoff mouth of pipe on one side, another mouth of pipe thermal welding internal thread 5 is as the interface of outside heating part.On plastics manifold trunk 3, go out a link slot 11 by the mould hot melt, also can open a link slot 11 in the above by planer, plastics comb absorber plate 6 is inserted in the link slot 11, adopt hot melt, TECHNOLOGY OF WELDING PLASTICS such as ultrasonic that it is tightly connected, interface welding material 12 should water-fast, heatproof, withstand voltage.The plastics comb absorber plate 6 of plastics manifold trunk 3 will have been welded, put into the plastic flat-plate heat collector shell 8 of having filled heat-insulation layer 7, hollow transparent plastic cover plate 9 on the upper cover, the last first-selected plastic flat-plate heat collector housing made from injection mo(u)lding 1, the also plastic flat-plate heat collector housing 1 that can plastic material be assembled into by adhesion, seal cover is tight to be reinforced.
