Abstract

The invention provides a plastic flat plate collector involving in the field of solar energy collector. As the core pats of the development and use of domestic solar heat energy, the high coat and inconvenient installment of solar energy collector has become an obstacle of general use for solar heat energy. In order to solving the problem of heavy whole body, limited fixing and high cost of solar heat energy, this invention provides 1 plastic flat plate solar energy collector with simple structure and lightweight. It is made of plastic flat plate out frame and shell, plastic collection pipe, plastic calandria heat-sink board, insulating layer and plastic hollow transparency cover plate. It has many advantages, such as simple structure, low cost and light weight and so on.

Description

Plastic flat-plate heat collector

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 need many and water tank directly be connected 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 so good as flat plate collector.And existing flat plate collector adopts glass cover-plate mostly, the metal absorber plate, though can with the water tank partial installation, whole heavy, the also only suitable roof of cost height is installed.As flat plate collector as described in the patent No. 200420047222.0 is exactly the glass cover-plate that adopts, so the also only suitable roof of full copper heat-collecting plate core is installed.

Summary of the invention;

In order to overcome solar thermal collector, integral body weighs, is only limited to the problem that the roof is installed, cost of manufacture is high.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.Its plastics comb absorber plate is the transparent plastic that adopts withstand voltage, heatproof, good weatherability, but make be shaped to hollow and in the plastic plate of many little combs of water flowing is arranged, simultaneously coat solar selective coat at it and form.On the plastics manifold trunk, have the link slot that can be communicated with the comb absorber plate.Plastics comb absorber plate inserts and adopts the sealing of temperature resistant structural adhesive stick bonding in the plastics manifold trunk link slot.

The invention has the beneficial effects as follows that simple in structure, manufacturing cost reduces greatly, overall weight alleviates greatly.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;

Make the plastic flat-plate heat collector shell 6 of similar square box shape by injection mo(u)lding, the inside filling light thermal insulation material is formed heat-insulation layer 3.By the transparent plastic of extrusion modling with withstand voltage, heatproof, good weatherability, but the hollow of making and in the transparent plastic sheet material of many water flowing float pipes 7 is arranged, simultaneously coating solar selective coat 8 at it just becomes plastics comb absorber plate 2.Adopt the heatproof plastic pipe as manifold trunk 4, adopt the hot melt shutoff mouth of pipe on one side, another mouth of pipe is as the interface with water tank.On plastics manifold trunk 4, open a link slot 9 in the above with planer, plastics comb absorber plate 2 is inserted in the link slot 9 with temperature resistant structural adhesive stick sealing adhesion, with facing down of scribbling solar selective coat 8, put into the plastic flat-plate heat collector shell 6 of having filled heat-insulation layer 3, hollow transparent plastic cover plate 5 on the upper cover, plastic flat-plate heat collector housing 1 lid made with injection mo(u)lding at last is tight.
