Description

Highly dense aluminium foil U-shaped comb flat plate collector

Technical field

The utility model relates to the solar thermal collector technical field, especially a kind of highly dense aluminium foil U-shaped comb flat plate collector.

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 with ultrasonic bonding or laser weld that copper pipe is connected with absorber plate; The face of contact has only a line; Thermal energy transfer is limited, has hindered effective conduction of heat energy, causes the thermal efficiency of solar thermal collector not high.Heat-collecting plate core by aluminium foil, " U " shape comb and water nozzle are formed connects as one aluminium foil, " U " shape comb, has improved the contact-making surface between absorber plate and the runner, is one of effective measures that improve the solar thermal collector thermal efficiency.

The utility model content

The purpose of the utility model is a kind of highly dense aluminium foil U-shaped comb flat plate collector that provides to the deficiency of prior art; Form heat-collecting plate core by aluminium foil, " U " shape comb and water nozzle; Aluminium foil, " U " shape comb are connected as one; Increase the contact area of runner and absorber plate, effectively strengthened the heat conductivility of heat-collecting plate core, thereby improved the thermal efficiency of solar thermal collector.

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

A kind of highly dense aluminium foil U-shaped comb flat plate collector, its characteristics comprise framework, toughened glass panel, heat-collecting plate core, aluminium sheet, heat-insulation layer and sealing ring; Said framework is the four limit bodies that aluminium section bar surrounds, and the one of which side is provided with four water nozzle holes and vacuum orifice, and said heat-collecting plate core is made up of aluminium foil, " U " shape comb and water nozzle; Said aluminium foil is a sheet; Its face is provided with plate hole, and " U " shape comb is the linker that several " U " shape pipe is in series, and water nozzle is located at two terminations of " U " shape comb; " U " shape comb is two-layer and parallel stacking, and several pieces aluminium foils are sleeved on two-layer " U " shape comb through plate hole successively; Said aluminium sheet, heat-insulation layer, heat-collecting plate core and toughened glass panel are loaded in the framework by bottom to surface layer successively, and 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 utility model is formed heat-collecting plate core by aluminium foil, " U " shape comb and water nozzle; Aluminium foil, " U " shape comb are connected as one; Increase the contact area of runner and absorber plate, effectively strengthened the heat conductivility of heat-collecting plate core, thereby improved the thermal efficiency of solar thermal collector.
