Description
Technical field
The present invention relates to the solar thermal utilization new technology, be specifically related to a kind of heat collectors for solar water heater.
Background technology
Solar energy is most important basic power source in the various regenerative resources, and biomass energy, wind energy, ocean energy, water energy etc. are all from solar energy, and in a broad sense, solar energy comprises above various regenerative resource.Since the seventies, in view of the finiteness of conventional energy resource supply and the increase of environmental protection pressure, many in the world countries have started the upsurge of development and use solar energy and regenerative resource, and the technology of utilizing of solar energy enters new developing stage.Solar energy is a kind of as regenerative resource, then is meant the direct conversion and the utilization of solar energy.Solar radiant energy is converted to the solar energy utilization technique that belongs to of heat energy utilization by conversion equipment.Domestic solar thermal utilization aspect mainly contains solar water heater, solar cooker, passive solar house and solar dryer.Through for many years effort in the past, China's solar thermal utilization reaches a standard substantially in these four art, scientific and technological achievement changes small lot batch manufacture to some extent over to, the coverage rate that has had some to apply has been received actual effect alleviating various places conventional energy resource shortage and alleviate aspects such as ecology and ecological deterioration.
Solar water heater generally uses in China in recent years.As shown in Figure 1, China utility model patent CN2695862Y discloses a kind of tube-plate solar heater's heat collector on 04 27th, 2005, comprise framework 2, be arranged in tube-sheet type thermal-arrest plate 1, heat-insulation layer 3 on the framework, and the transparent cover plate 6 that is arranged in thermal-arrest plate top, arrange transparent warming plate 5 at thermal-arrest plate 1 and 6 of transparent cover plates, this transparent warming plate 5 is supported on the framework 2 by two press strips 4.As shown in Figure 2, China utility model patent CN2495955Y discloses a kind of heat collector of solar water heater on 06 19th, 2006, heat collector housing 7 is peviform, be provided with all fixed grooves along the surface, limit in its level, cover plate 3 peripheral suit seal trim strips 2, the lug, nib on the seal trim strip 2 is located in housing 7 along in the groove on limit; Ceiling molding 1 and following press strip 6 tighten cover plate 3 and housing 7 along the bottom surface, limit from cover plate 3 peripheral top surface and housing 7 respectively; Pushing heat conduction inner core band 4 compound, the inflation moulding is to constitute by adding copper pipe between aluminium strip and the copper strips.
The operation principle of above-mentioned solar water heater mainly absorbs solar energy by the heat absorption plate and transmits heat for the water pipe that is clipped in the middle of the heat absorption plate water temperature to be raise utilize solar energy.Its weak point is need very large-area heat absorption plate, and the heat absorption plate uses the metal material of copper, aluminium basically, and cost is higher comparatively speaking.
Summary of the invention
At the prior art above shortcomings, technical problem to be solved by this invention is to have proposed a kind of novel heat collectors for solar water heater.This heat collectors for solar water heater utilizes prism optically focused to strengthen light intensity, by the effect of prism optically focused sunlight being concentrated under the irradiation of sunlight accumulates on the endothermic tube, and concentrate absorption solar energy that heat dump is heated up rapidly, give the closely metallic water pipe of contact of heat dump thermal energy transfer then.
In order to solve the problems of the technologies described above, the heat collectors for solar water heater that the present invention proposes is embedded in the framework, and its innovative point is, is made up of a plurality of prisms; A face at each prism all posts one deck reflective film, and another side then all is equipped with the water pipe of band heat dump; The water pipe of the band heat dump that above-mentioned a plurality of prism another side is installed is arranged in parallel.
As the preferred embodiments of the invention, preferably use high printing opacity, low thermal conductivity and refractive index to carry out bonding at the interface of heat dump and prism heat dump light entrance face near the material of glass.
With respect to prior art, the present invention utilizes prism optically focused to strengthen light intensity, and light enters prism from the prism sensitive surface, and the light that arrives prism one side that heat dump is installed is then directly absorbed by heat dump; Arrive the light that pastes reflective film prism one side and be reflected back to prism sensitive surface and air interface, because the refractive index of prism glass is about 1.5, therefore when reflection ray from the optically denser medium to the optically thinner medium and incident angle greater than under the critical angle situation total reflection takes place, through a total reflection or repeatedly total reflection make light enter prism one side that heat dump is installed and absorbed by heat dump.The light of entrance prism sensitive surface all is absorbed in prism installation heat dump side by reflection and total reflection as a result.The optically focused multiplying power of prism just the prism sensitive surface area and the ratio of area of prism one side of heat dump is installed, and recently the improving of the area of area that the optically focused multiplying power of prism can be by increasing the prism sensitive surface and prism one side that heat dump is installed.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
As shown in Figure 3-4, the heat collectors for solar water heater that a preferred embodiment of the present invention proposes is embedded in framework interior (indicating among the figure), is made up of a plurality of prisms 11; A face at each prism 11 all posts one deck reflective film 12, and another side then all is equipped with the water pipe 15 of band heat dump 13; The water pipe 15 of the band heat dump 13 that above-mentioned a plurality of prism 11 another sides are installed is arranged in parallel.Preferably use high printing opacity, low thermal conductivity and refractive index to carry out bonding near the material 14 of glass at the interface of heat dump 13 and prism heat dump light entrance face.As shown in Figure 4, heat collectors for solar water heater accumulates on the endothermic tube 13 by the effect of prism optically focused sunlight being concentrated under the irradiation of sunlight, and concentrate absorption solar energy that heat dump is heated up rapidly, give the closely metallic water pipe of contact of heat dump thermal energy transfer then.
Be to use the fundamental diagram of solar water heater of the heat collectors for solar water heater of the foregoing description as Fig. 5.Flow to the prism heat collector under the cold water, the prism heat collector is under the irradiation of sunlight, by the effect of prism optically focused sunlight being concentrated accumulates on the endothermic tube, and concentrate absorption solar energy that heat dump is heated up rapidly, give the closely metallic water pipe of contact of heat dump thermal energy transfer then, hot water rises to heat preservation storage water tank naturally.Cold water and hot water are by the circulation of prism heat collector.
