Problems solved by technology

Under this atmospheric pressure factor, in order to increase the support of the upper cover and reduce the stress on the material in the structure of the solar collector, the upper cover or the heat collecting plate must be protruded greatly outward, so that It will increase the volume of the collector, the complexity of the structure and the production cost, especially the curved upper cover will block the incidence of sunlight and reduce its heat collection

Embodiment Construction

[0030] Please refer to figure 2 and image 3 As shown, a flat-plate vacuum solar collector 1 according to a first embodiment of the present invention includes an upper cover 2, a supporting device, a heat collecting plate 3, a lower cover 4, a heat insulating layer 5 and an outer frame 6.

[0031] The upper cover 2 is in the shape of a flat plate, which is arranged on the first side of the heat collecting plate 3, and is made of a light-transmitting material, such as glass, polycarbonate, polyester with glass fiber, acrylic (acrylic resin), Or other transparent materials with high sunlight penetration and high mechanical strength. The upper cover 2 may be surface treated to reduce the reflectivity of sunlight.

[0032] The heat collecting plate 3 is generally in the shape of a flat plate, and is preferably made of copper, aluminum, stainless steel or other metal or plastic materials with good thermal conductivity. When the upper cover 2 is disposed on the first side of th...

Abstract

The invention provides a flat-plate typed vacuum solar heat collector comprising a heat collecting plate, an upper cover, a supporting device, a lower cover and a heat-insulating layer, wherein the light can penetrate the upper cover which is arranged at a first side of the heat collecting plate; the supporting device is arranged between the upper cover and the heat collecting plate and comprises a plurality of supporting components; the heat collecting plate and the upper cover are divided by the supporting components; an internal space is arranged between the heat collecting plate and the upper cover; the internal space is in a vacuum state; the lower cover is arranged at a second side of the heat collecting plate; and the heat-insulating layer is arranged at the external side of the lower cover and the heat collecting plate.

Description

technical field [0001] The invention relates to a flat-plate vacuum solar heat collector and a solar heat collecting device, in particular to a solar heat collector with a supporting device between the heat collecting plate and the upper cover to disperse the atmospheric pressure on the upper cover. Background technique [0002] The amount of heat collected by a flat-plate solar collector is equal to: the heat energy after deducting the heat energy (ie heat loss) dissipated by convection and radiation on the surface of the heat collector plate from the solar heat absorbed by the heat collector plate, so if the heat can be reduced The loss can improve the heat collection efficiency of the solar collector. [0003] Please refer to figure 1 , the existing flat-plate solar collectors include a top cover 10, a heat collecting plate 11, a heat insulation layer 12 and an outer frame 13. There is an inner space between the upper cover 10 and the heat collecting plate 11 . The inn...
