Abstract

The utility model relates to a plate solar thermal collector which comprises a solar thermal collecting plate, an input fluid converging pipe, an output fluid converging pipe, an insulating layer and a shell; a tubular flow passage of the solar thermal collecting plate and a thermal collecting plate-fin are made of the same metal and manufactured into a whole body, a solar thermal collecting layer is coated or plated on the surface of the solar thermal collecting plate facing the sunshine, and a dentoid or flaky heat exchange fin is arranged on the inner wall of the tubular flow passage. The plate solar thermal collector has the advantages that the utilization area of photo-thermal conversion is large, the efficiency is high, the thermal resistance of heat exchange is little, and the heat exchange area of heat transfer medium flowing in the tubular flow passage and the tubular flow passage is large, so that heat transfer speed is rapid, and the difference in temperature between the heat transfer medium and the solar thermal collecting plate is reduced.

Description

A kind of flat-plate solar heat collector

Technical field

The utility model belongs to solar utilization technique, particularly a kind of flat-plate solar heat collector

Background technology

Existing solar thermal collector has vacuum glass tubular type heat collector, though this heat collector single tube collecting efficiency is higher, can have only about half of area occupied for the effective area of photo-thermal conversion but its reality of combination back is installed, and glass tube is frangible, meets strong wind, hail and often causes damage; The thermal-arrest plate of existing flat type solar heat collector is at the sheet metal back side that is provided with photothermal transformation layer the heat transfer mozzle to be set; though be the cambered surface contact; and be connected as a single entity with soldering or gas shielded arc welding etc.; but scolder and inevitable gap will produce big thermal resistance; influence heat-transfer effect, and production process is many, globality is poor, production cost is higher.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of photo-thermal conversion efficiency height, effectively collector area is big, heat transfer resistance is little, good integrity, shock resistance is superior, production routine is simple, production cost is low, can be installed in the flat-plate solar heat collector on building balcony, wall and the roof easily and reliably.

The technical solution of the utility model is: comprise being provided with 2 tubulose runners at least, meet the sunlight surface and scribble or be coated with the solar heat-collection plate of solar energy heating layer, be located at solar heat-collection plate both sides and the input conflux pipe that is connected with the tubulose runner and output conflux pipe, front portion at solar heat-collection plate is provided with euphotic cover plate, rear portion and periphery at solar heat-collection plate are provided with heat-insulation layer and encase input conflux pipe and output conflux pipe, shell is located at the outside of heat-insulation layer and pushes down the edge of euphotic cover plate, and the thermal-arrest wing plate of described tubulose runner and solar heat-collection plate is made in one piece by metal material of the same race.

The inwall place of described tubulose runner is provided with the heat exchange fin of dentation or sheet.

Described be provided with the tubulose runner and with the tubulose runner be the solar heat-collection plate of metal material of the same race thermal-arrest wing made in one piece plate, can be monoblock or the splicing of many sticks.

The utility model has the advantages that: effectively photo-thermal conversion area is big, the conversion efficiency height, owing to be provided with heat exchange fin at tubulose runner inner wall place, increased the heat exchange area of heat transfer medium, dwindled the temperature difference of heat transfer medium and solar heat-collection plate effectively, because tubulose runner and thermal-arrest wing plate are that metal material of the same race is made in one piece,, have not only reduced cost and also helped industrialization, standardized production so oversimplify fabrication schedule, improved reliability.
