Abstract
The utility model discloses a flat plate solar energy heat collector, which comprises a box-shaped container, wherein a heat insulation layer, an absorption body and a glass cover plate are sequentially arranged in the box-shaped container, the absorption body comprises a copper pipe and an aluminum wing plate, the copper pipe and the aluminum wing plate are connected through laser welding, and bonding agents resisting the temperature higher than 150 DEG C is coated between the copper pipe and the aluminum wing plate. The flat plate solar energy heat collector has the advantages of high connection intensity, low heat resistance, high heat collection efficiency and the like and is particularly applicable to solar water heaters.
Description
Technical field
The utility model relates to a kind of flat-plate solar collector, specifically a kind of flat-plate solar collector that adopts binding agent to reinforce laser weld copper aluminium absorber.
Background technology
Flat-plate solar collector comprises case type container, is disposed with heat insulation layer, absorber and glass cover-plate in case type container.Existing flat-plate solar collector generally adopts laser weld copper pipe aluminium finned sheet absorbing body, can bring into play on the corrosion-resistant and aluminium wing plate of copper pipe and can directly make the advantage of anodic oxidation selective absorbing film, and avoid that the investment of manufacturing inflation copper aluminum composite pipes absorber is big, copper pipe is subjected to repeatedly destructive yielding shortcoming in manufacturing process.But the laser weld copper pipe aluminium finned sheet absorbing body of existing flat-plate solar collector is easy to generate the defective of Joint Strength weakness because the solder joint distribution is not really intensive.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of bonding strength height, thermal resistance is low, collecting efficiency is high flat-plate solar collector.
For solving the problems of the technologies described above, a kind of flat-plate solar collector of the utility model comprises case type container, in described case type container, be disposed with heat insulation layer, absorber and glass cover-plate, described absorber comprises copper pipe and aluminium wing plate, described copper pipe links to each other with aluminium wing plate laser weld, is coated with the anti-binding agent of temperature more than 150 ℃ between described copper pipe and aluminium wing plate.
Above-mentioned a kind of flat-plate solar collector, the binding agent that evenly is coated with between the copper pipe of described absorber and the aluminium wing plate is the silica gel binding agent that is mixed with powdered graphite.
Above-mentioned a kind of flat-plate solar collector, described silica gel binding agent is the neutral silica gel binding agent.
The utility model is owing to adopted above-mentioned technical pattern, and it had both kept the work habit that absorber adopts existing laser welding apparatus to process, and can keep higher output; Improve the copper pipe of absorber and the bonding strength between the aluminium wing plate again at an easy rate, and utilized binding agent to greatly reduce the copper pipe of absorber and the thermal resistance between the aluminium wing plate, helped improving the collecting efficiency of flat-plate solar collector.Evenly be coated with the silica gel binding agent that is mixed with powdered graphite between the copper pipe of the absorber of flat-plate solar collector and the aluminium wing plate, can further increase the capacity of heat transmission of binding agent.The solarization of the sky below 150 ℃ temperature, variations in temperature and ultraviolet ray irradiation are insensitive once in a while to flat plate collector for silica gel.Because the silica gel binding agent can room temperature vulcanization, thereby in process of production, just directly enter assembly process after the adhesive-coated, help reducing production costs and improving output.Adopt neutral silica gel binding agent can also be reduced to minimum degree to the corrosiveness of metal surface.
Description of drawings
Fig. 1 is the structural representation of the utility model flat-plate solar collector.
The specific embodiment
As shown in Figure 1, the utility model flat-plate solar collector comprises case type container 1, is disposed with heat insulation layer 2, absorber 3 and glass cover-plate 4 in case type container 1.Absorber 3 comprises copper pipe 5 and aluminium wing plate 6, and copper pipe 5 and aluminium wing plate 6 are connected together the aperture 7 that has laser weld to produce on the aluminium wing plate 6 by laser weld.Aperture 7 has reduced the intensity at solder joint place.Between copper pipe 5 and aluminium wing plate 6, require evenly to be coated with ability temperature more than 150 ℃, be mixed with the neutral silica gel binding agent 8 of powdered graphite according to low thermal resistance, make bonding strength between copper pipe 5 and the aluminium wing plate 6 be strengthened, connect thermal resistance and reduced.
