Abstract
A flat-plate solar heat collector mainly comprises an heat receiver, a transparent cover plate, a thermal insulating layer and a casing, after a solar radiation light generates through the transparentcover plate, the light is projected on the heat receiver and absorbed by the heat receiver to be converted into the heat energy, then the heat is transferred to a heat transferring working substancein the heat receiver. The heat receiver can radiate the heat toward the surrounding by the conductance, the convection, the radiation and the like, thus the flat-plate heat collection device has fastheat collection and fast heat radiation. The cover plate of the corrugated flat-plate solar heat collector is made of hollow vacuum double-layer translucent materials, an accumulator is attached to the rear portion of the corrugated heat receiver and packaged by the insulating layer, thus effective preventing the heat convection and thermal conduction due to the temperature rise of the heat collector. The heat absorption plate on the heat receiver is corrugated by the frosted finish, compared with the flat-plate, the corrugated absorption plate has the projection of the same area, but the areaincrease by 25%, thus acquiring the solar light farthest. The corrugated surface can decrease the reflection of the solar light, and acquire the solar radiation energy farthest.
Description
Technical field:
The utility model relates to a kind of ripple flat plate collector.
Background technology:
Flat plate collector has that modularization is strong, thermal-arrest is fast, be easy to building in conjunction with, safe characteristics, and this is that other solar heat collector can't be compared.Flat plate collector in the market is mainly by absorber, transparent cover plate, thermal insulation layer and shell four most of form (as Fig. 1).After the transparent cover plate 2 that is arranged on the housing 1 is passed in solar radiation, be incident upon on the absorber 3, absorbed by absorber and convert heat energy to, then with the heat-transfer working medium in the heat transferred absorber 4, heat-transfer working medium is transported to useful energy and is stored in the heat storage water tank and utilize.Meanwhile, though the protection of thermal insulation layer 5 is arranged, absorber since temperature raise inevitably by modes such as conduction, convection current and radiation to around heat radiation, become the thermal loss of heat collector, so flat plate collector has fast, the also fast characteristics of dispelling the heat of thermal-arrest.
Present absorber shape has tube-sheet type, wing pipe type, flat box type and coil pipe type etc.But the problem of all these flat plate collector maximums is present on absorber and the transparent cover plate: 1, absorber plate all is to spray coating for selective absorption on the smooth metal plate, because the flat reflectivity height that causes of plate face light, it is few to receive solar irradiation light; 2, because absorber plate is that so effectively endotherm area is little on the plane; 3, the conduction of single-layer and transparent cover plate heat is big, the convection current heat waste is big.
The utility model content:
In order to solve the shortcoming that exists in the above-mentioned flat plate collector, the utility model provides that a kind of thermal-arrest is fast, heat waste is little, good heat insulating, ripple flat plate collector that security performance is high.
The utility model comprises framework, be arranged on euphotic cover plate on the framework, be arranged on absorber under this light-passing board, be arranged on the heat-insulation layer between framework and the absorber, and is arranged on working medium accumulator behind the absorber plate; It is characterized in that: described absorber plate is bellows-shaped, and described working medium accumulator is shaped as flat, and described transparent cover plate is double-deck.
Absorber plate of the present utility model surface is the rough top layer after texturing is handled, and the working medium accumulator closely links to each other with absorber plate, and double-deck transparent cover plate is hollow or vacuum.
Absorber of the present utility model has two characteristics: 1, the absorber plate on the whole absorber is corrugated, the advantage of this kind way is: the projection with same area, the ripple endotherm area is bigger by 25% than dull and stereotyped heat dump area, so can obtain sunshine to greatest extent.2, the texturing processing is carried out on ripple absorber plate surface, makes it to form rough surface, and then sprays selective heat absorbing coating, makes it to reduce sun reflection of light, obtains the solar radiation energy to greatest extent.
3, close attachment is flat at absorber plate accumulator behind, and the one, can contact with the absorber plate large tracts of land, the 2nd, the energy on the energy fast Absorption absorber plate.
Cover plate of the present utility model has adopted " hollow or vacuum " double-deck euphotic cover plate, its maximum advantage is effectively to have stoped thermal convection current and the heat conduction that raises and cause owing to the heat collector temperature, fully reduced the heat loss in the heat collector, solved that the flat plate collector thermal-arrest is fast, the shortcoming of rapid heat dissipation.
Description of drawings:
Fig. 1 is prior art constructions figure;
Fig. 2 is a partial sectional view of the present utility model;
Fig. 3 is a side view cutaway drawing of the present utility model.
The specific embodiment:
By Fig. 2 and shown in Figure 3, the ripple flat plate collector that the utility model provides is made up of framework 11, hollow or vacuum euphotic cover plate 7, ripple absorber plate 9, flat working medium accumulator 10 and heat-insulation layer 6.Framework does not have loam cake, and the euphotic cover plate of double-deck hollow or vacuum is arranged on the one side of no loam cake, with frame fixation together.Be arranged within the framework after waveform absorber plate and the welding of working medium accumulator, keep certain space between hollow or vacuum euphotic cover plate and the absorber plate, heat-insulation layer is arranged between absorber plate and the framework.The ripple absorber plate is the sheet metal that has selective heat absorbing coating, and the rough layer of surface after texturing is handled heats the working medium in the working medium accumulator rapidly after absorbing heat.Accumulator is " eight " font and vertically installs, its advantage is to utilize natural characteristic that heat makes progress to reduce thermal resistance, the two ends flat runner 8 that has a traverse to put is attached thereto up and down, energy after working medium heats up in the accumulator is passed to be stored in the heat storage water tank and is utilized, thereby reaches better heating effect.
