Description

Be provided with the flat-plate solar collector of laminated aluminum paillon foil

Technical field

The utility model relates to the solar heat-collection plate technical field, especially a kind of flat-plate solar collector that is provided with the laminated aluminum paillon foil.

Background technology

Solar thermal collector is warm for huge numbers of families have sent to as a kind of product of energy-conserving and environment-protective, and solar water heater receives the favor of vast family deeply.But the problem that exists is; Mostly the flat-plate solar collector of prior art is tube-sheet type, and it is to adopt ultrasonic bonding or laser weld that copper pipe is connected with absorber plate, and the contact-making surface of copper pipe and absorber plate has only a line; Hinder effective conduction of heat energy, caused the thermal efficiency of solar thermal collector not high.Increasing the contact-making surface between copper pipe and the absorber plate, is the effective measures that improve the solar thermal collector thermal efficiency.

The utility model content

The purpose of the utility model is a kind of flat-plate solar collector that is provided with the laminated aluminum paillon foil that provides to the deficiency of prior art; The utility model adopts " U " shape pipe to pass the heat-collecting plate core that several pieces aluminium foils are processed; Coat heat absorbing coating again; The heat absorption efficiency of aluminium foil is improved, and aluminium foil improves to the efficient of " U " shape pipe conduction heat energy, thereby improves the thermal efficiency of solar thermal collector.

The concrete technical scheme that realizes the utility model purpose is:

A kind of flat-plate solar collector that is provided with the laminated aluminum paillon foil, its characteristics comprise framework, toughened glass panel, heat-collecting plate core, aluminium sheet, heat-insulation layer, sealing ring and termination cover plate; Said framework is the four limit bodies that aluminium section bar surrounds; The one of which side is provided with two water nozzle holes, and said heat-collecting plate core is made up of aluminium foil, " U " shape pipe and water nozzle, and said aluminium foil is several pieces; Its face is provided with several pores; Several pieces aluminium foils are arranged in parallel, and the pore that " U " shape pipe passes several pieces aluminium foils successively is connected to a passage, and water nozzle is connected with the two-port of passage; Said termination cover plate is two; Said aluminium sheet, heat-insulation layer, heat-collecting plate core, termination cover plate and toughened glass panel are loaded in the framework by bottom to surface layer successively; Wherein the termination cover plate is divided into the dual-side of framework; The water nozzle of heat-collecting plate core is stretched out by the water nozzle hole of framework, and sealing ring is located between water nozzle hole and the framework; The outer surface of described aluminium foil scribbles heat absorbing coating.

The utility model adopts " U " shape pipe to pass the heat-collecting plate core that several pieces aluminium foils are processed, and coats heat absorbing coating again, and the heat absorption efficiency of aluminium foil is improved, and aluminium foil improves to the efficient of " U " shape pipe conduction heat energy, thereby improves the thermal efficiency of solar thermal collector.

The specific embodiment

Consult Fig. 1, Fig. 2, the utility model comprises framework 1, toughened glass panel 2, heat-collecting plate core 3, aluminium sheet 4, heat-insulation layer 5, sealing ring 6 and termination cover plate 7; The four limit bodies that said framework 1 surrounds for aluminium section bar, the one of which side is provided with two water nozzle holes 11;

Consult Fig. 3, Fig. 4; Said heat-collecting plate core 3 is made up of aluminium foil 31, " U " shape pipe 32 and water nozzle 33; Said aluminium foil 31 is several pieces, and its face is provided with several pores, and several pieces aluminium foils 31 are arranged in parallel; The pore that " U " shape pipe 32 passes several pieces aluminium foils 31 successively is connected to a passage, and water nozzle 33 is connected with the two-port of passage;

Consult Fig. 1, Fig. 2; Said termination cover plate 7 is two; Said aluminium sheet 4, heat-insulation layer 5, heat-collecting plate core 3, termination cover plate 7 and toughened glass panel 2 are loaded in the framework 1 by bottom to surface layer successively; Wherein termination cover plate 7 is divided into the dual-side of framework 1, and the water nozzle 33 of heat-collecting plate core 3 is stretched out by the water nozzle hole 11 of framework 1, and sealing ring 6 is located between water nozzle hole 11 and the framework 1; The outer surface of described aluminium foil 31 scribbles heat absorbing coating 8.

The utility model is to use like this:

Consult Fig. 1, Fig. 2, Fig. 5; Heat collector framework 1 is installed on the roof; To adding heat-conduction mediums in " U " shape pipe 32, the water nozzle 33 that both sides is stretched out heat collector framework 1 is connected the medium circulation loop that formation is sealed through medium input pipe 16, medium efferent duct 17 with coil pipe 10 two ends in the heater through water nozzle 33; During work; The toughened glass panel 2 that the solar energy of radiation sees through heat collector framework 1 is absorbed by the aluminium foil 31 of heat-collecting plate core 3, and the body that conducts to " U " shape pipe 32 through aluminium foil 31 heats heat-conduction medium, circulation between coil pipe 10, medium input pipe 16 and " U " shape pipe 32 of heat-conduction medium in medium efferent duct 17, heater; " U " shape pipe 32 absorbs heat energy in heat collector framework 1, in heater, discharge heat energy and carry out heat exchange through coil pipe 10;

Consult Fig. 3, Fig. 4; Simultaneously; The toughened glass panel 2 that the solar energy of radiation sees through heat collector framework 1 is absorbed by the aluminium foil 31 of heat-collecting plate core 3, because aluminium foil 31 is a stacked arrangement, can better absorbs the solar energy of radiation and be transmitted to " U " shape through aluminium foil 31 and manage on 32; Make " U " shape pipe 32 obtain more thermal energy, thereby improve the absorptivity of flat plate collector radiant energy.
