The utility model content

The purpose of the utility model is that a kind of pressing plate that provides to the deficiency of prior art does not have welding U-shaped tube solar heat-collecting device; The opposite side that contacts with " U " shape copper pipe at absorber plate increases a pressing plate; Also increased the contact area of " U " shape copper pipe and absorber plate to " U " shape copper pipe when being pressed on the absorber plate; Effective increased thermal conductivity ability, thereby the thermal efficiency of raising solar thermal collector.

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

A kind of pressing plate does not have welding U-shaped tube solar heat-collecting device; Its characteristics comprise framework, heat-absorbing plate core, termination cover plate, toughened glass panel, aluminium sheet, heat-insulation layer and sealing ring; Said framework is the four limit bodies that aluminium section bar surrounds, and framework one side is provided with entery and delivery port, and said heat-absorbing plate core is made up of " U " shape copper pipe, absorber plate and pressing plate; Said pressing plate is several; Which is provided with bayonet socket, be flat on the absorber plate after the several series connection of " U " shape copper pipe, pressing plate is connected with absorber plate through bayonet socket clamping " U " shape copper pipe; Said termination cover plate is two; Said aluminium sheet, heat-insulation layer, heat-absorbing 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; Entery and delivery port is connected with the two-port of " U " shape copper pipe, and sealing ring is located between entery and delivery port and the framework; Said heat-absorbing plate core is provided with the one side of " U " shape copper pipe towards heat-insulation layer, and the one side that is provided with absorber plate is connected with the termination cover plate.

The utility model adds a pressing plate owing to be employed in absorber plate with the opposite side that " U " shape copper pipe contacts; Also increased the contact area of " U " shape copper pipe and absorber plate to " U " shape copper pipe when being pressed on the absorber plate; Effective increased thermal conductivity ability, thereby the thermal efficiency of raising solar thermal collector.

The specific embodiment

Consult Fig. 1, Fig. 2, the utility model comprises framework 1, heat-absorbing plate core 2, termination cover plate 3, toughened glass panel 5, aluminium sheet 6, heat-insulation layer 7 and sealing ring 8, the four limit bodies that said framework 1 surrounds for aluminium section bar, and framework 1 one sides are provided with entery and delivery port 11;

Consult Fig. 3, Fig. 4; Said heat-absorbing plate core 2 is made up of " U " shape copper pipe 21, absorber plate 22 and pressing plate 23, and said pressing plate 23 is several, which is provided with bayonet socket; Be flat on the absorber plate 22 after the 21 several series connection of " U " shape copper pipe, pressing plate 23 is connected with absorber plate 22 through bayonet socket clamping " U " shape copper pipe 21;

Consult Fig. 1, Fig. 2; Said termination cover plate 3 is two; Said aluminium sheet 6, heat-insulation layer 7, heat-absorbing plate core 2, termination cover plate 3 and toughened glass panel 5 are loaded in the framework 1 by bottom to surface layer successively; Wherein termination cover plate 3 is divided into the dual-side of framework 1, and entery and delivery port 11 is connected with the two-port of " U " shape copper pipe 21, and sealing ring 8 is located between entery and delivery port 11 and the framework 1; Said heat-absorbing plate core 2 is provided with the one side of " U " shape copper pipe 21 towards heat-insulation layer 7, and the one side that is provided with absorber plate 22 is connected with termination cover plate 3.

The utility model is to use like this:

Consult Fig. 1, Fig. 2, Fig. 5; Heat collector framework 1 is installed on the roof; Toughened glass panel 5 up, to adding heat-conduction mediums in " U " shape copper pipe 21, the entery and delivery port 11 that both sides is stretched out heat collector framework 1 is connected with coil pipe 10 two ends in the heater through medium input pipe 16, medium efferent duct 17 through water inlet 11; Constitute the medium circulation loop of sealing; During work, the toughened glass panel 5 that the solar energy of radiation sees through heat collector framework 1 is absorbed by the absorber plate in the heat-absorbing plate core 2 22, and heat is transmitted to " U " shape copper pipe 21 through absorber plate 22; Through the heating of the heat-conduction medium in 21 pairs of bodys of " U " shape copper pipe; Circulation between coil pipe 10, medium input pipe 16 and " U " shape copper pipe 21 of heat-conduction medium in medium efferent duct 17, heater, " U " shape copper pipe 21 absorbs heat energy in heat collector framework 1, in heater, discharge heat energy and carry out heat exchange through coil pipe 10;
