Abstract
The utility model discloses a flat-plate solar collector. An outer shell is composed of a profile frame of the flat-plate solar collector and a back plate of the flat-plate solar collector, the opening face of the outer shell is sealed and covered by a piece of flat-plate glass, a thermal insulating layer is arranged inside the outer shell, and a polyurethane thermal insulation layer is arranged between the thermal insulating layer and the outer shell. The aluminum profile frame of the flat-plate solar collector has the advantages of being firm, reliable, not prone to aging and deformation, good in sealing performance and the like, and therefore the flat-plate solar collector is long in service life and high in heat collecting efficiency. Meanwhile, compared with a flat-plate solar collector with the back plate formed through overall stamping, the flat-plate solar collector has the advantages that the size of the aluminum profile frame of the flat-plate solar collector is easy to adjust, production can be conducted through dies, and therefore the flat-plate solar collector is high in production efficiency and simple, and technological operation can be easily and conveniently conducted.
Description
Technical field
The utility model relates to flat-plate solar collector, relates in particular to the shell structure of heat collector.
Background technology
Along with the destruction of environment and the continuous scarcity of resource, people more and more pay attention to the utilization of regenerative resource.Solar thermal collector is the device that absorbs solar energy and the heat of generation is delivered to heat transfer medium.Plate type solar with other solar thermal collector, compare have that collecting efficiency is high, bearing capacity is strong, good looking appearance and be easy to building and combine.
Common flat-plate solar collector mainly is comprised of several parts such as shell, transparent cover plate, absorber plate, thermal-collecting tube, heat-insulation layer, backboards in the market, and wherein heat-insulation layer generally adopts rock wool or mineral wool.When panel solar was worked, solar radiation passed transparent cover plate and projects on absorber plate, and absorber plate absorbs solar energy and is converted into heat energy, via heat transfer medium, was delivered to thermal-collecting tube simultaneously.
The shell of flat-plate solar collector is mainly two kinds of the whole punching press flat-plate solar collectors of aluminium section bar group frame flat-plate solar collector and backboard, the whole punching press flat-plate solar collector of its dorsulum is because of the single difficult adjusting of its size, has the shortcomings such as manufacturing process is complicated.
Aluminium section bar group frame generally adopts rock wool or mineral wool as the heat-insulation layer material, but due to rock wool or the mineral wool self seal poor, easy characteristics such as aging and not environmental protection, and when corner connected, tightness was poor, easily form heat bridge phenomenon, so when absorber plate absorption solar radiation raises the absorber plate temperature, this moment the heat energy changed of absorber plate with by heat collector inner air and outside air formation convection current, cause scattering and disappearing of heat, simultaneously, heat energy also can be by mode distribute heats such as radiation, and then causes the collecting efficiency of heat collector greatly to reduce.The thermal convection current effect of air easily makes the element surface oxidation of heat collector inside and is corroded in addition.In addition, because the powder such as rock wool or mineral wool are larger, in the production installation process, easily workman's health is produced to infringement.
The utility model content
Technical problem to be solved in the utility model is to realize that a kind of to have manufacture craft simple, the flat-plate solar collector of the aluminium section bar group frame shell of long service life.
To achieve these goals, the technical solution adopted in the utility model is: a kind of flat-plate solar collector, its section bar frame and backboard form shell, described shell aperture face is by the plate glass capping, described shell inboard is provided with thermal insulation layer, and is provided with polyurethane insulation coating between thermal insulation layer and shell.
Described polyurethane insulation coating is formed by the polyurethane foam that is poured between thermal insulation layer and shell.
Described section bar frame is aluminium section bar, and described backboard is aluminium or steel.
Between described section bar frame and plate glass, be provided with seal.
Described seal arranges along section bar scuncheon edge, and its cross section is L-shaped.
Described section bar frame is provided with perfusing hole, and described perfusing hole is provided with capping.
The characteristics such as the edge frame made of aluminum profiles of this flat-plate solar collector is solid and reliable, is difficult for aging distortion, and tightness is good, increased the flat-plate solar collector long service life, and collecting efficiency is high.With the whole punching press flat-plate solar collector of backboard, compare simultaneously, this described aluminium section bar group frame panel solar size is easily adjusted, and can carry out mold production, makes flat-plate solar collector production efficiency described in the utility model high, and technological operation is easy.
The accompanying drawing explanation
Below the content of every width accompanying drawing expression in the utility model specification and the mark in figure are briefly described:
Fig. 1 is the flat-plate solar collector structural representation;
Mark in above-mentioned figure is: 1, section bar frame; 2, backboard; 3, polyurethane insulation coating; 4, plate glass; 5, heat absorbing core plate; 6, plate core runner; 7, thermal insulation layer; 8, seal.
The specific embodiment
Participation Fig. 1 is as can be known, and flat-plate solar collector forms shell by section bar frame 1 and backboard 2, and the opening surface of shell is by plate glass 4 cappings, and inner formation heat collector cavity, be used to installing the parts such as heat absorbing core plate 5, plate core runner 6.
Section bar frame 1 is adopted as aluminium profile usually, backboard 2 adopts aluminium or steel to make usually, shell inboard in section bar frame 1 and backboard 2 formations is provided with thermal insulation layer 7, and between thermal insulation layer 7 and shell, be provided with polyurethane insulation coating 3, these polyurethane insulation coatings 3 are formed by the polyurethane foam that is poured between thermal insulation layer 7 and shell.In order to facilitate filling polyurethane, at section bar frame 1, be provided with perfusing hole, and perfusing hole is provided with capping, in order to ensure perfusion evenly, internal voids is few, can a perfusing hole all be set in section bar frame 1 four sides, and be equipped with respectively capping.
The polyurethane insulation coating 3 of perfusion can be used as insulation by thermal insulation layer 7, section bar frame 1 and backboard 2 encapsulation adhesion together, makes the heat collector corner all seal and put in place, improves collector efficiency.And polyurethane foam material to workman's health without any infringement, safety non-pollution.
Because shell is polyurethane integral foaming carrier, because aluminium section bar can be according to house balcony and roofing size change size, can carry out mold production, make the utility model flat-plate solar collector have the advantages such as production efficiency is high, simple process, solved the size that prior art exists single, the problems such as complex process, occupation of land face are large, production efficiency ground.
Between section bar frame 1 and plate glass 4, be provided with seal 8, seal 8 is to arrange along section bar frame 1 inside edge, and its cross section is L-shaped, can better seal whole heat collector like this, further improves the sealing thermal insulation performance of flat-plate solar collector.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
