Description

A kind of heat-pipe flat-plate type solar thermal collector

Affiliated technical field

The utility model relates to the heat-pipe flat-plate type solar thermal collector that is suitable in a kind of solar energy heat utilization field, it is improved products on former patented technology ZL92223171.0 utility model basis, adopted " a kind of fin heat pipe of gradual change section " new patented technology in the heat collector, its structure is: by the bolt of disconnected heat bridge, with the fin union pipe of the fin heat pipe of gradual change section, gradual change section, up and down two complex heat-preservation shells, transparent cover plate and up and down two metal edge frames be assembled successively.Be characterized in: the red copper heat pipe and the red copper collector that substitute reducing with isometrical aluminium fin heat pipe and aluminium fin collector, material cost reduces greatly, simplified manufacturing process, processing cost is low, be suitable for the large-scale production of industrialization streamline, the collecting efficiency of product improves, and aesthetics is improved, can directly substitute construction materials such as corresponding construction wall and pitched roof, economic performance is good.

Background technology

At present, the structure of known common collection calandria circulation flat plate collector: be by copper aluminium compound many combs and the bigger two red copper collectors up and down of diameter, the heat-absorbing plate core of processing through complexity for one, be assembled to again in the insulation cladding with metal shell, last capping transparent cover plate forms the circulating flat-plate solar collector with greenhouse effects.The shortcoming that this heat collector exists is: 1, the heat-absorbing plate core copper consumption is many, the material cost height; 2, complex process is difficult to realize the streamline automated production, the manufacturing cost height; 3, the comb internal cause leak water and be afraid of to freeze, problem such as corrosion and scaling is comparatively outstanding, maintenance rate is higher; 4, collecting efficiency is higher, but heat loss is bigger; 5, be full of water (or other liquid) in the collection comb in the heat collector, the potential danger of seepage is arranged; 6, the outer rim of heat collector mostly is whole aluminium alloy extrusions, has the heat conduction problem, is not suitable for installing with architecture-integral.Because above defective, this product are used in market and are under some influence.

A kind of optically focused-hot pipe type solar heat collector the product that reaches described in the ZL92223171.0 utility model, the structure of heat collector shell and circulation flat plate collector is basic identical, just the heat-absorbing plate core in the heat collector is that fin heat pipe with many arrangements forms one by mode and one (or two) union pipe with well that condensation segment inserts, heat pipe wherein, sleeve pipe and union pipe generally all are to adopt the red copper material, copper consumption is more, cost is higher, technology is also comparatively complicated, heat transfer property is difficult to reach design level, and this structure assembling mode aesthetics is not high, thereby in using, market is under some influence.

Summary of the invention

In order to overcome the shortcoming of common collection calandria circulation flat plate collector and ZL92223171.0 utility model optically focused-hot pipe type solar heat collector product, the utility model provides a kind of novel heat pipe flat plate collector.Heat-absorbing plate core has adopted the fin heat pipe of gradual change section and the heat exchange collector of gradual change section, with the sticking mutually one that is pressed in the plane of two parts; The complex heat-preservation shell divides two parts up and down, by the method realization of mould foaming; Transparent cover plate with the sealing joint strip bound edge or after smearing glass cement, is embedded in the window of insulation cladding, in the middle of together heat-absorbing plate core being enclosed in following insulation cladding again, forms the heat collector core of an integral body; For resolving heat bridge, metal shell also is divided into two frames up and down, in the middle of the heat collector core is fastened on, is tightened to complete heat collector integral body with screw and insulation long nut again.

The technical scheme that its technical problem that solves the utility model adopts is; Adopt heat-conducting glue with the aluminium fin heat pipe of gradual change section and the sticking heat-absorbing plate core that presses to one of aluminium fin heat exchange collector of the gradual change section after the inner surface plating, eliminated the backward frame mode of heat pipe condensation end insertion collector, the diameter that has reduced collector reduces cost, and heat exchange efficiency is stably improved, improved the interior aesthetics of product simultaneously; The assembly structure of the shell of complex heat-preservation up and down, transparent cover plate and the heat-absorbing plate core of mould foaming helps streamline production, boosts productivity, and further reduces cost and improves the outer aesthetics of product; Two metal edge frames are by the insulated bolt method that the thermal-arrest core is fastening up and down, save material than using whole metal edge frame, reduce cost, disconnected the heat bridge at the heat collector surface and the back side, when directly substituting construction wall with heat collector, can reach the effect of body of wall thermal insulation, also help and promote the attractive in appearance of building.

The beneficial effects of the utility model are: save a large amount of copper materials, reduce material cost, the mold of part, make work simplification, help realizing automated production, effectively raise productivity ratio, manufacturing cost is reduced, the frame mode of each parts and quality of fit strengthen the solar collecting performance of heat collector.
