Abstract
The utility model relates to the field of solar energy utilization, in particular to a high-temperature thin flat plate solar collector, which comprises a transparent glass cover plate, a heat-absorbing plate, a racking pipe, an outer casing, an inner casing and the like. The high-temperature thin flat plate solar collector is characterized in that a layer of silicon dioxide aerogel is arranged below the glass cover plate; and a layer of vacuum heat-insulating plate is arranged below the heat-insulating plate. Compared with other similar products, the high-temperature thin flat plate solar collector not only is thin in thickness, but also can obtain relatively-high heat-collecting efficiency at the same temperature.
Description
Technical field
The utility model relates to field of solar energy utilization, particularly relates to high temperature thin flat plate solar heat collector
Background technology
The daylighting area of flat plate collector with equate that with endotherm area therefore opposite with China, developed country's flat plate collector proportion is higher than solar vacuum tube collector.But, flat plate collector is because heat-insulating property is not so good, can not adopt the vacuum insulation method again, must use 2 layers of glass cover-plate at cold district, and as long as the sunlight transmitance of 2 layers of glass is approximately 64%, when flat plate collector is used for high temperature (as about 90 ℃ of refrigeration needs) thermal-arrest, except absorber plate must be made the selective coating, also need below glass cover-plate, add transparent mineral wool (U.S.) etc. and reduce the heat waste of heat from cover plate one side, even but transparent mineral wool, light transmittance is also not so good, and the heat-insulating property of mineral wool is not very very good.Heat collector backboard heat loss amount is also very big, has a kind of thermal-arrest plate that the heat loss that cellular board reduces backboard is set below absorber plate, and still, cellular board thickness is bigger.
The content of utility model
The purpose of this utility model provides the flat plate collector that a kind of thickness is little, heat loss is little and the transmitance of sunlight is high, to overcome existing technical deficiency.
A kind of high temperature thin flat plate solar heat collector by the design of this purpose comprises formations such as transparent glass cover-plate, absorber plate, comb, shell and inner casing, it is characterized in that being provided with below the described glass cover-plate the solid-state aerosil of one deck suitable thickness.At aerosil and absorber plate with leave the space of the suitable spacing of one deck on every side, simultaneously, comb will be arranged on below the absorber plate, can make like this to keep smooth above the absorber plate, runs into comb and absorber plate with the surface that prevents aerosil.In addition, in order to improve the counter-bending ability of aerosil layer, also can in aerosil, sneak into a spot of glass fibre.
A vacuum heat-insulating plate is set below the described absorber plate.
Other structure is similar with the ordinary flat solar heat collector.
Compare with other similar products, the utility model not only thickness is low, and can obtain higher relatively collecting efficiency under same temperature.
Description of drawings
Fig. 1 is the generalized section of an embodiment of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1, Ben Gaowen thin flat plate solar heat collector comprises formations such as transparent glass cover-plate 1, absorber plate 3, comb 4, shell 6 and inner casing 8.Attach the solid-state aerosil 2 of one deck suitable thickness below the described glass cover-plate 1.The molten gel of silica gas is a kind of near complete transparent solid-state heat-insulating material, its heat-insulating property is best in all heat-insulating material, but it is highly brittle simultaneously, definitely can not push, crooked, therefore, at present a lot of occasions can't be used this material now, in order to prevent the aerosil fragmentation, between layer of silicon dioxide aerosol 2 and absorber plate 3 and inner casing 8, to leave the space 7 of the suitable spacing of one deck, cause aerosil 2 surfaces to run into absorber plate 3 to prevent glass cover-plate 1 because of a small amount of distortion that external force such as extruding cause, this quite hangs aerosil 2 get up.Simultaneously, comb 4 will be arranged on below the absorber plate 3, can make like this to keep smooth above the absorber plate 3, preventing protruding combs 4 above the absorber plate 3, because aerosil 2 surfaces of the part of protruding above being easy to run into when glass plate 1 distortion.In addition,, also can in aerosil, sneak into a spot of glass fibre, just as adding the counter-bending ability that reinforcing bar can improve cement in the concrete in order to improve the counter-bending ability of aerosil 2.
Below the described absorber plate 3 one deck vacuum heat-insulating plate 5 is set.Vacuum heat-insulating plate is commercialization at present, not bad nearly 10 times of its heat-insulating properties than polyurethane foam, it is a heat-insulating material such as filling mineral wool etc. between two-layer aluminium foil, and adds getter, be evacuated then, do thermal insulation layer with vacuum heat-insulating plate and have good heat insulating and frivolous characteristics.
Claims (4)
