Abstract
The utility model relates to a flat-plate solar heat-collecting plate body with liquid flow channels adopting special pipes. The flat-plate solar heat-collecting plate body comprises a heat-collecting plate molded according to design and the liquid flow channels, wherein the heat-collecting plate adopts a flat plate, the liquid flow channels are welded on the solar heat-collecting plate, and when liquid transfers heat, a plane is arranged at the contact point between the liquid flow channel and the heat-collecting plate, and the heat-transfer area is increased by a plurality of times, so that, the heat collecting effect is greatly enhanced. The flat-plate solar heat-collecting plate body has the advantages of simple structure, convenient installation, strong mechanical property, high heat collecting performance, and improved price-to-performance ratio of the products.
Description
Technical field
The utility model relates to the big flow channel for liquids structure of a kind of flat-plate solar collector transmission of heat by contact face, relates in particular to a kind of flat panel solar heat collecting plate body of special pipe flow channel for liquids.
Background technology
At present common flat plate solar water heater is mainly by the thermal-arrest plate, flow channel for liquids (metallic conduit), cover plate, heat-insulation layer and shell are formed, along with solar energy industry in technology, be gradually improved on performance and the structure, just structure does not wait requirement with the building combination, use and the same life-span of building, also require to have high heat transfer efficiency, between the flat plate collector thermal efficiency 25-50% in the market, flow channel for liquids is circular pipeline, the thermal-arrest plate is that line contacts with flow channel for liquids, contact-making surface is little, and the time of heating is long, when the sun is exposed to the sun, be very easy to cracking., the common low problem of heat transfer efficiency that exists.
Summary of the invention
In order to overcome above-mentioned shortcoming, the purpose of this utility model is to provide a kind of flat panel solar heat collecting plate body of simple in structure, easy for installation, special pipe flow channel for liquids that solar collecting performance is high.
To achieve these goals, the technical scheme that the utility model adopted is: the flat panel solar heat collecting plate body of special pipe flow channel for liquids, it comprises the thermal-arrest plate that designs moulding, flow channel for liquids is characterized in that described thermal-arrest plate is dull and stereotyped, and flow channel for liquids is welded on the solar heat-collection plate, when liquid heat transfer, flow channel for liquids and thermal-arrest plate contact position are planes, increased several times heat transfer area, so Heat-collecting effect have very large raising.
Described flow channel for liquids can be semicircle, oval or square filleted corner.
The utlity model has simple in structurely, easy for installation, mechanical performance is powerful, high solar collecting performance, and improved cost performance of product.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples;
Fig. 1 is that the utility model flow channel for liquids is the structure cutaway view of semicircle or D font;
Fig. 2 is that the utility model flow channel for liquids is the structure cutaway view of square filleted corner shape.
Among the figure, 1, the liquid heat transfer runner, 2, solar heat-collection plate.
The specific embodiment
As shown in the figure, the flat panel solar heat collecting plate body of special pipe flow channel for liquids, it comprises the liquid heat transfer runner 1 that designs moulding, solar heat-collection plate 2, described thermal-arrest plate 2 are dull and stereotyped, and flow channel for liquids 1 is welded on the solar heat-collection plate 2, when liquid heat transfer, flow channel for liquids 1 is planes with thermal-arrest plate 2 contact positions, increased several times heat transfer area, so Heat-collecting effect has very large raising.The utlity model has simple in structurely, easy for installation, mechanical performance is powerful, high solar collecting performance, and improved cost performance of product.
