Abstract
The invention discloses a natural convection solar absorber plate. A manner of mounting wing fins on a back plate is adopted, a sunlight absorber plate is arranged on a front metal plate, and a plurality of wing fins are arranged on a rear metal plate and are used for ventilation and heat exchange; and after the solar absorber plate is connected with a heat pump, the absorber plate can absorb sunlight and heat energy in air at the same time, design of a heat pump system is more reasonable, mounting is more convenient, and the energy-saving effect is more obvious.
Description
Technical field
The present invention relates to a kind of transducing plate for heat conversion of art of heat pumps, is a vitals of air energy thermal pumping system.
Background technology
At present, air energy heat pump technology and the use of equipment in South China Urban are very universal very ripe, and a large amount of examples has also confirmed that air energy heat pump technology and equipment are the good products of good technology that a kind of energy-conserving and environment-protective are benefited the nation and the people.But air energy heat pump technology and equipment but do not obtain universal and development in north cold area, this is because the temperature on average of Shelter in South China Cities whole year is higher than about 10 °, energy content in air is higher, the heat quality of air is high, air energy heat pump is made to present higher energy-saving effect, but north cold area due to the longer temperature of winter months lower normal lower than about-10 °, energy content in air is lower, the heat quality of air is low, air energy heat pump is made to present lower energy-saving effect, not remarkable even, thus limit air energy heat pump and apply in north cold area.
Even but in Shelter in South China Cities, but although the heat quality of the higher still high only sunshine of the heat quality of air, if air energy heat pump also can absorb the energy of sunshine, that will make energy-saving effect significantly promote, but the transducing plate that existing air energy heat pump uses but can only absorb heat from air, and can not absorb the heat of sunshine.Now in order to make up the weak point of air energy heat pump, and have employed a kind of way that sunshine transducing plate is set in air energy thermal pumping system, this way can improve the energy-saving effect of heat pump really effectively, but existing sunshine transducing plate is mainly in order to accept sunshine design, remarkable to the heat effect absorbed in air, thus make solar energy heat pump system become Energy Efficiency Ratio reduction much at the night of north cold area.
Summary of the invention
Realizing to solve the problem improving the energy-saving effect of solar energy heat pump system in north cold area comprehensively, just must improve sunshine transducing plate simultaneously and absorb the efficiency of sunshine and absorb the effect of heat in air.Allow one block of sunshine transducing plate can efficient absorption sunshine again can heat in efficient absorption air, the technical scheme taked is: free convection solar absorber plate, comprise solar absorber plate, several wing sheet, it is characterized in that: solar absorber plate forms its surface by metallic plate or inside is provided with runner, runner is provided with import and outlet, can be trickled in runner liquid or gas, on metallic plate, be also provided with sunshine heat absorption composite membrane, be provided with several wing sheet in back.To weld on a metal plate or to have made the runner that can pass through for fluid by technological means, the opening of runner connects with the corresponding port of heat pump respectively, wing sector-meeting makes air flow in the gas channel formed by metal covering, on front metal plate, appearance has made one deck efficient sunlight absorption film, therefore this module can efficient absorption sunshine again can efficient absorption from the heat energy the air that metal covering flows fast through.
Thus the present invention has multinomial obvious advantage owing to have employed technique scheme: 1. the thermal efficiency of efficiency light hot dip film can reach more than 90% at present, so the thermal efficiency of this module also can reach more than 90%, and the thermal efficiency of the metal bare board generally adopted at present is the highest just can reach 60%.2., because this module has the absorption function of highly effective air heat energy, so can replace the air transduction piece in heat pump main frame completely, and then the structure of heat pump main frame is greatly simplified, volume greatly reduces, easier for installation.3. adopt this module that solar-energy air-energy heat pump can be made more efficient and simplify.

The surperficial solar energy coating of 1. metal solar plate 2. panel runner 3. flow channel entry point 4. runner exit 5. wing sheet 6. in figure.
Detailed description of the invention
Be made up of metal decking and runner and surperficial solar energy coating in FIG, numerous wing sheet is made in sheetmetal back, metal coil pipe can be welded on below metallic plate by runner, also technological process for blowing can be adopted to make in metallic plate, the upper surface of this metallic plate also will make one deck efficient sunlight absorbing film by technical matters, runner two holes are connected with heat pump machine, so working medium will be sprayed in the pressure-bearing runner on metallic plate when heat pump machine is started working, a large amount of heats will be drawn to metallic plate when working medium is vaporized in runner, if and the heat of sunshine will be siphoned away rapidly when now having solar irradiation to be mapped on top panel metallic plate, if and when now there is no sunlight, a large amount of air is then had to flow through from metal wing sheet, heat in air also can be absorbed by metallic plate, such metallic plate has just possessed the characteristic of simultaneously stability sunshine and air energy, so far this module just becomes the necessary vitals of of solar-energy air-energy heat pump machine system.
When heat pump adopts this module, just can no longer design and installation wing sheet in heat pump mainframe box, so the volume of heat pump mainframe box just can reduce greatly, install just more convenient, and this module compared with conventional solar energy bare board just thickness and weight slightly increase, install still very convenient.
