Abstract
The utility model relates to a flat plate collector with a vacuum interlayer. The flat plate collector with the vacuum interlayer comprises an aluminum alloy shell, wherein the upper portion of the aluminum alloy shell is open. A heat insulating layer is arranged in an inner layer of the aluminum alloy shell, a double-layer transparent glass cover plate is arranged at the position of an opening of the aluminum alloy shell, the vacuum interlayer is arranged between an upper layer and a lower layer of the double-layer transparent glass cover plate, and a tube-plate type heat absorbing body is arranged below the transparent glass cover plate. According to the flat plate collector with the vacuum interlayer, the large defects of natural convection losses and radiant heat losses existing in a traditional flat plate collector are overcome, radiation losses can be greatly reduced, and conversion efficiency of the collector can be remarkably improved.
Description
Technical field
The utility model relates to solar energy heat utilization field, is a kind of novel flat-plate solar collector with vacuum interlayer.
Background technology
Flat plate collector on the market all is made up of shell, heat-insulation layer, absorber and transparent cover plate now.Owing between absorber and transparent cover plate, there is bigger space, make free convection loss and radiation heat loss all bigger, cause the collecting efficiency of heat collector low, limited the popularization of heat collector.
The utility model content
The utility model provides a kind of flat plate collector with vacuum interlayer of new structure, has overcome traditional flat plate collector and has had all big defectives of free convection loss and radiation heat loss.
The technical scheme that its technical problem that solves the utility model adopts is:
Flat plate collector with vacuum interlayer, the Al-alloy casing that comprises upper opening, the Al-alloy casing internal layer is provided with heat-insulation layer, the opening part of described Al-alloy casing arranges the double-layer transparent glass cover plate, being vacuum interlayer between described double-layer transparent glass cover plate up and down two-layer, is the tube-sheet type absorber below the described clear glass cover plate.
Described tube-sheet type absorber comprises absorber plate and endothermic tube, and the surface of described absorber plate is solar selectively absorbing coating, and described endothermic tube is copper core pipe, and described endothermic tube is distributed in the absorber plate below.
Described heat-insulation layer adopts polyurethane material.
When solar radiant energy see through have the clear glass cover plate of vacuum interlayer after, its heat is absorbed by the absorber plate that the surface scribbles coating for selective absorption, heat is transferred to medium in the endothermic tube, as the useful energy output of heat collector, heat collector bottom and being incubated with heat-insulating material all around.Because vacuum interlayer can see through solar radiation, has excellent heat insulating function again, therefore can eliminate the natural convection air heat loss between absorber surface and the cover plate, and can reduce radiation loss greatly, can significantly improve the transformation efficiency of heat collector, and this heat collector can be made standard size according to the design of building and use the combination of be more convenient for solar energy and building as member.
Description of drawings
Fig. 1 is the internal view with flat-plate solar collector of vacuum interlayer.
Among the figure: 1. Al-alloy casing; 2. heat-insulation layer; 3. endothermic tube; 4. absorber plate; 5. vacuum interlayer; 6. double-layer transparent glass cover plate.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, flat plate collector with vacuum interlayer, the Al-alloy casing 1 that comprises upper opening, Al-alloy casing 1 internal layer is provided with heat-insulation layer 2, the opening part of described Al-alloy casing 1 arranges double-layer transparent glass cover plate 6, be vacuum interlayer 5 between described double-layer transparent glass cover plate up and down two-layer, described double-layer transparent glass cover plate 6 is following to be the tube-sheet type absorber.
Described tube-sheet type absorber comprises absorber plate 4 and endothermic tube 3, and the surface of described absorber plate 5 is solar selectively absorbing coating, and described endothermic tube 3 is copper core pipe, and described endothermic tube 3 is distributed in absorber plate 4 belows.
Described heat-insulation layer 2 adopts polyurethane material.
When solar radiant energy see through have the double-layer transparent glass cover plate 6 of vacuum interlayer 5 after, its heat is absorbed by the absorber plate 4 that the surface scribbles coating for selective absorption, heat is transferred to medium in the endothermic tube 3, as the output of the useful energy of heat collector, heat collector bottom and use the heat-insulating material polyurethane heat-insulation all around.Because vacuum interlayer 5 can see through solar radiation, has excellent heat insulating function again, therefore can eliminate the natural convection air heat loss between tube-sheet type absorber surface and the glass cover-plate, and can reduce radiation loss greatly, can significantly improve the transformation efficiency of heat collector, and this heat collector can be made standard size according to the design of building and use the combination of be more convenient for solar energy and building as member.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
