Abstract

The invention discloses a coil pipe-shaped solar air heat collector. A heat absorption plate of the air heat collector is a metal plate coated with a selective absorption coating on the sunward surface, and a snake bend is welded on the rear surface of the metal plate. The snake bend enables the heat absorption stroke of the air in the heat collector to be longer, so that the temperature of the air in the outlet of the heat collector is increased.

Description

The coil pipe type solar energy air heat collector
One, technical field
The present invention relates to solar energy heat utilization field, refer in particular to the solar energy air heat collector of a kind of snake bend of metallic plate and the back side thereof the welding that is coated with coating for selective absorption with one deck sunny slope as heat absorbing part.
Two, background technology
The plate type solar air collector is a kind of solar energy heat collector that utilizes air for medium, is highly suitable for fields such as heating in solar energy building, dehumidifying, industrial or agricultural dry materials.Compare with the vacuum tube type solar energy heat collector, advantage such as that the plate type solar air collector has is simple in structure, the sunlight footprint is big, seal request is low, it is antifreeze not need, cleaning, response are fast, but also have shortcomings such as heat loss is big, collecting efficiency is low.How further to improve the collecting efficiency of plate type solar air collector, be the target that the scientific research personnel pursues always.
The plate type solar air collector mainly is made up of transparent cover plate, absorber plate, insulation shell three parts.During work, the absorber plate that scribbles coating for selective absorption is converted into heat energy with solar radiation, and heat is passed to flow air through heat conduction and convection current.Because air tends to away shortest path from import to outlet (being usually located at the two ends of absorber plate clinodiagonal), and the buoyancy convection current can take place after being heated in air, so air-flow is difficult to evenly flow through absorber plate top each point.Therefore, the plate type solar air collector since air-flow easily " short circuit " cause heating uneven, make the air can not be efficiently and the absorber plate heat exchange, become the principal element that influences its collecting efficiency.
To the problems referred to above of plate type solar air collector, existing some kinds of corrective measures.For example: patent " a kind of binary channels waveform central layer solar energy air heat collector " (patent publication No. CN200986333); The above and below that it is characterized in that absorber plate is separated into two heat tunnels with heat collector cavity; Increased the path that air heats in heat collector, adopted the wave mode heat collection chip to increase collector area simultaneously and strengthen the disturbance of air.Patent " tortuous flow doubleeffect heating solar heat-collector air heat collectors " (patent publication No. CN101178260A); Between absorber plate and insulation base plate, adopt the airtight hot-flow flue that adds; Adding the thermal-collecting tube that vacuum heat-preserving is set again above the hot-flow flue; Make gas do secondary cycle between hot-flow flue and the vacuum heat collection pipe and flow adding, so that obtain better heat exchange.
The enforcement of above-mentioned patent all has certain effect to the thermal efficiency that improves solar energy air heat collector, plunders the formula heat convection but still belong to traditional plate between air and the absorber plate, and the increase rate of the thermal efficiency is less.
Three, summary of the invention
A kind of coil pipe type solar energy air heat collector that the present invention proposes, this heat collector is made up of air inlet, absorber plate, air outlet, snake bend, insulation shell and transparent cover plate, and wherein absorber plate is the metal sheet that a sunny slope is coated with coating for selective absorption.The absorber plate back side is welded with snake bend, and the snake bend material is selected the good material of thermal conductivity for use, makes heat be delivered to snake bend from metallic plate rapidly.The heat collector air inlet is on top, and air outlet is in the bottom.Under fan action, air gets into snake bend from air inlet, flows out from air outlet behind the snake bend of flowing through.Air flows in snake bend, has increased the heat absorption stroke, has improved the hot air temperature of outlet.
Four, description of drawings
Gather accompanying drawing below, the present invention is described further.
Fig. 1 is the schematic appearance of this device.
Fig. 2 is the A-A face cutaway view of this device.
The position of marking is respectively among the figure: 1, air inlet; 2, air outlet; 3, transparent cover plate; 4, absorber plate; 5, snake bend; 6, insulation shell.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further.
The external blower fan of the present invention.Sunlight sees through transparent cover plate 3 and is radiated on the absorber plate 4, because the effect of spectral selective absorbing coating, absorber plate 4 becomes heat energy with conversion of solar energy, and produces high temperature.Heat is delivered on the snake bend 5 of metallic plate back side welding, and its temperature is raise.When the user need use hot blast, start blower fan, air flows into snake bend 5 equably through air inlet 1, with snake bend 5 abundant heat exchange, flows out from air outlet 2 at last.
