Description

Hot plates of wall type solar energy collector
Technical field
The utility model belongs to a kind of solar thermal collector and the manufacture method thereof in Application of Solar Energy field, particularly a kind of hot plates of wall type solar energy collector.
Technical background is in Solar Energy Heat Utilization System, and heat collector is a critical product.The Application of Solar Energy of China is started late, and China's solar thermal collector is based on glass vacuum tube type at present, accounts for 63.16%.The solar thermal collector of all-glass vacuum tube is low because of its heat-collecting temperature, collector area is limited, can only be placed on the first-class shortcoming of roof, has hindered the application and the development of solar thermal collector.Therefore, the development flat-plate solar heat collector is a direction of Application of Solar Energy from now on.Existing flat-plate solar heat collector, a kind of heat collecting element is the flat-plate solar heat collector that is made of the composite plate core that copper pipe and aluminium fin form, because the coefficient of expansion of copper and aluminium is different, after repeatedly expanding with heat and contract with cold, the two can produce bigger thermal resistance, make heat loss more, cause collecting efficiency not high.Another kind is the heat pipe flat-plate solar heat collector that developed recently gets up, its baseset thermal element structure is to connect a fin with its one on heat pipe, the heat absorption fin bigger by area absorbs solar heat, and pass on the heat pipe with its one, condensation end and heat exchanger heat-shift by heat pipe, these heat pipes are installed in the housing, the loam cake of housing is equipped with transparent glass or plastics sunlight board, because the contact area of fin and heat pipe is very little, the solar heat that fin absorbed has only part to pass on the heat pipe, so the integrated heat efficiency of heat collector is relatively low, in addition, the steam working medium and the condensed liquid refrigerant that rise owing to be heated all will be from the slype processes in the heat pipe, and the path is obstructed up and down for working medium, has also influenced the thermal efficiency.Moreover, being subjected to the restriction of the confined space in the body of wall, the daylighting face of body of wall heat collector is difficult to accomplish vertical with incident light or near vertical, makes that the thermal efficiency is not high under the identical situation of daylighting area; Simultaneously, because existing heat pipe flat-plate solar heat collector, because of its heat-collecting part is a heat pipe one by one, and the production process of heat pipe is many and complicated, be unfavorable for working continuously on a large scale, so production efficiency is lower comprehensive production cost height.
The utility model content
The purpose of this utility model is to provide a kind of integrated heat efficiency height, integrated cost low, hot plates of wall type solar energy collector that can mechanizeding continuous operation.
Hot plates of wall type solar energy collector provided by the utility model, heat collector places in the sunny slope body of wall of building or in the space of reserving, be characterized in that described hot plates of wall type solar energy collector is by being parallel to each other on the hot plate support, tilted-putted N piece hot plate is formed, N 〉=2, the incident light of N piece hot plate does not block mutually, hot plate is a rectangular slab, thermal-collecting tube on the hot plate is by on the hot plate metal shell, vertical with the base one by one cavity that the weld seam on lower surface and connection two sides forms, described heat exchanger is the horizontal heat exchanging chamber that places the top of thermal-collecting tube to communicate with these thermal-collecting tubes, there is heat exchanger tube to pass through in the heat exchanging chamber, described heat exchanger tube advances, go out the sealing of heat exchange cavity place and heat exchange cavity, heat-insulation layer is arranged below the hot plate.
Hot plates of wall type solar energy collector provided by the utility model by be parallel to each other on the hot plate support, tilted-putted N piece hot plate forms, N 〉=2, the incident light of N piece hot plate does not block mutually.This structure, on the one hand because the body of wall heat collector is to be made of the polylith hot plate, make that most time is in limited body of wall space in 1 year, can make the daylighting face of each piece hot plate vertical with incident ray or approaching vertical, under the identical situation of daylighting area, improved the collecting efficiency of hot plate greatly, because it is more little to be mapped to the incidence angle (angle between incident ray and daylighting face normal) of heat collector daylighting surface sunlight, the solar energy that the heat collector unit are is received is just many more, the solar energy that is received is directly proportional with the incident cosine of an angle, the angle that departs from the sunlight direct projection when the daylighting face of heat collector is big more, and the solar energy that is absorbed is few more.The structure of hot plates of wall type solar energy collector provided by the utility model increases the solar heat that is absorbed on the interior unit daylighting area of the confined space greatly, thereby strengthened its collecting efficiency, simultaneously, because the thermal-collecting tube on the hot plate of composition hot plates of wall type solar energy collector is by on the hot plate metal shell, vertical with the base one by one cavity that the weld seam on lower surface and connection two sides forms, the housing of hot plate promptly is the housing of each heat pipe, just the housing of hot plate is direct, integrally adopt heat, the solar heat of these collections is all directly passed to the working medium in the hot plate, reduce the thermal loss in the conductive process, also improved the thermal efficiency.Because heat exchanger is the horizontal heat exchange cavity that places thermal-collecting tube top to communicate with thermal-collecting tube, has heat exchanger tube to pass through in the heat exchanger, the sealing of heat exchanger tube into and out of horizontal heat exchange cavity place and heat exchange cavity.Make and comprise that placing the whole hot plate of the horizontal heat exchange cavity that communicates with thermal-collecting tube above the thermal-collecting tube is a vacuum seal body that communicates up and down, in the horizontal heat exchange cavity that communicates with thermal-collecting tube above working medium rises to after being subjected to thermal evaporation, directly with behind the condenser pipe heat-shift lean on gravity current backheat plate heat affected zone after the liquefy working medium, be heated again, evaporate ... so circulation, current downflow is unobstructed on the working medium, has further improved heat exchange efficiency again.The condenser pipe of hot plates of wall type solar energy collector in the utility model in placing the horizontal heat exchanging chamber in hot plate top, remainder all is to make of a sheet metal, is convenient to mechanization and produces in enormous quantities, and therefore efficient height, the cost of producing is low.Hot plates of wall type solar energy collector provided by the utility model places in the sunny slope body of wall of building owing to heat collector, can directly make solar thermal collector on solar thermal collector under the window, the window, body of wall solar thermal collector, balcony solar thermal collector etc., inlet tube and outlet tube all can be hidden within body of wall, can save construction material and construction cost greatly on the one hand, solar thermal collector has formed organic the combination again with building on the other hand.
Hot plates of wall type solar energy collector provided by the utility model can satisfy the requirement with whole buildingization, have thermal efficiency height, can mechanizeding continuous operation, advantage that integrated cost is low.
