Description
Technical field
The utility model belongs to field of solar energy, relates to a kind of high-efficiency solar air collector.
Background technology
Solar energy air heat collector is a kind of solar energy heat collector that utilizes air for working media, is applicable to fields such as building and heating, dehumidifying, agricultural product drying.In order to improve the thermal efficiency of solar energy air heat collector, forefathers have done number of research projects.The approach that improves the solar energy air heat collector thermal efficiency at present has: 1, suitably increase air mass flow, obtain sufficient solar radiation; 2, adopt technical measures such as reducing less spacing between heat collector width, maintenance absorber plate and base plate, employing selective coating; 3, adopt the transparent cover plate of honeycomb, it can suppress the heat loss at heat collector top; 4, arrange different fins on the absorber plate, utilize artificial rough surface, strengthen the convection heat transfer' heat-transfer by convection of air and absorber plate.But the single hole that traditional air collector adopts is into and out of air, and its inside will produce vortex movement.Thereby make that the heat exchange between air and absorber plate is inhomogeneous, hot-spot shortens the heat collector life-span, and collector efficiency is lower.
Summary of the invention
The purpose of the utility model is in order to overcome above deficiency, and a kind of efficient, cold-resistant, long-lived solar energy air heat collector is provided, and mainly solves the low utilization rate problem of cold district solar energy air heat collector.
The utility model is to realize with following scheme: a kind of high-efficiency solar air collector; Comprise heat collector shell (8), the thick polyurethane thermal insulation board of 5cm (7), sunlight board transparent cover plate (13), be coated with the thermal-arrest plate (9) of the V-type aluminium sheet of coating for selective absorption; Heat collector shell (8) is once molding formed by aluminium alloy plate; It is characterized in that on the both sides dividing plate (14) of heat collector shell (8), boring 10 diameters respectively air inlet aperture (6) that is 25mm, the aperture of giving vent to anger (5); Two dividing plates (14) outside forms an air inlet cavity runner (11) respectively, the cavity runner (10) of giving vent to anger; Two cavity runner skins are by the thick polyurethane foam insulation of 5cm; Air inlet aperture (6) on the dividing plate (14) is symmetrically distributed with respect to the aperture of giving vent to anger (5), and air flows to air inlet cavity runner (11) by indoor air inlet (2), outdoor air inlet (4) and gets into heat collector (12) by 10 air inlet apertures (6) again, flows through thermal-arrest plate (9) uniformly; Heated air flows into the cavity runner (10) of giving vent to anger from the aperture of giving vent to anger (5) of upper spacer (14) and compiles, and is flowed out by indoor air outlet (1), outdoor gas outlet (3) again.This product structure is simple, and is easy to use, and it had both reduced the inner flow blind angle of heat collector, and increased the effective heat exchange area of thermal-arrest plate and air, also improved the cold resistance of itself.

The specific embodiment
Below in conjunction with the preferred forms of accompanying drawing detailed description the utility model, solar energy air heat collector comprises: give vent to anger on air inlet aperture (6), the thick polyurethane thermal insulation board of 5cm (7), the thermal-arrest plate (9) that is coated with coating for selective absorption V-type aluminium sheet, sunlight board transparent cover plate (13), the dividing plate on heat collector shell (8), indoor air inlet (2), outdoor air inlet (4), air inlet cavity runner (11), dividing plate (14), the dividing plate aperture (5), the cavity runner (10) of giving vent to anger, indoor air outlet (1), outdoor gas outlet (3).
During use; Cold air gets into air inlet cavity runner (11) by indoor air inlet (2), outdoor air inlet (4) and compiles; Cross closable chamber's external admission mouth (4) when low when environment temperature, only by the indoor air that gets into heat collector that provides, the cold air that compiles evenly gets into heat collector by the air inlet aperture (6) on the dividing plate (14) and thermal-arrest plate (9) carries out heat exchange; The give vent to anger aperture (5) of hot-air on upper spacer (14) of exchange comes together in the cavity runner (10) of giving vent to anger; When indoor need the heating, the hot-air that comes together in the cavity runner (10) of giving vent to anger is again by in indoor air outlet (1) inlet chamber, and another outdoor gas outlet (3) is closed or is used as other thermal source and uses; Need not heat the time, close indoor air outlet (1) when indoor, open outdoor gas outlet (3).
