Description
Technical field
The present invention relates to field of solar energy utilization, especially relate to a kind of plate core technology of three-dimensional flat plate heat collector.
Background technology
Solar thermal collector is the core component that solar energy utilizes, divide inclined-plane installation system and metope installation system according to mounted angle, the vertically placed type solar thermal collector is an a kind of metope system, mainly being suitable for heat collector puts or vertically installs in that metope is perpendicular, also be suitable for the installation of other optional positions, the plate core of solar heat-collecting that the vertically placed type metope is installed comprises heat transfer tube and heat absorption fin etc., its working face often is designed to have the shape of reflection-absorption, characteristics are the direct light and the reverberation that can absorb from incident on a plurality of directions, transfer luminous energy to heat energy, electric energy or both output, its effective work area is more than a times of two-dimentional collector plate core, in addition, its heat absorption working face usually and in a certain angle between horizontal plane, thereby, often be designed to inclined-plane etc., also require the perpendicular installation back solar thermal collector of putting to keep higher heat absorption efficiency and heat transfer efficiency during as heat collector simultaneously, wherein, heat absorption efficiency is to lean on the absorbing structure characteristic of fin to realize, heat transfer efficiency then is to lean on the syndeton characteristic of fin and heat pipe to realize that collecting efficiency is made of jointly heat absorption efficiency and heat transfer efficiency two parts.
The Chinese patent CN2410591Y that has announced relates to the vertically arranged three-dimensional solar water heater of a kind of dull and stereotyped balcony sideboard type, it is characterized in that the placement of heat collector transverse horizontal, whole vertical the installation, the fin of the tube-sheet type absorber heat transfer tube in the heat collector is tilted-putted, its heat transfer tube and its fin are that the garden cylinder of heat pipe contacts fixedly connected with the line on fin plane, therefore, its heat transfer tube also is horizontal positioned, thereby, its end of inserting the heat-transfer pipe of union pipe is to be with the yaw that makes progress, the heat collector of this form is easily made the parapet-type structure and is organically combined with the building balcony, to avoid the influence of installation to architectural appearance.The design consideration accompanying drawing of fin heat absorption working face is the straight-tooth sawtooth pattern in the technique scheme, wherein, what make progress is subjected to light work straight-sided flank vertical with incident sunlight, again with reference to the accompanying drawings shown in, the non-light straight-sided flank that is subjected to is perpendicular, so just, can accept from the reverberation on the ground return direction, but square being inversely proportional to of light intensity and distance, actual light intensity from the ground reflection is very low, owing to be vertical between the two, so the reverberation direction on the addendum flank is approximate parallel with dedendum flank, and dedendum flank is very little to the reverberation absorbability from addendum flank, therefore, the reflection-absorption efficient of this straight-tooth serrated fin is very low, in addition, also is not suitable for the installation of other optional positions.
Another Chinese patent CN2284934 has adopted falling-in plate rib heat collector, its method is to adopt the plate core of forming dull and stereotyped three-dimensional heat collector perpendicular to the parallel blacking absorption blade and the heat transfer tube of heat transfer tube, heat collector and all vertical placement of plate core, wherein, absorb blade and be connected to blade profile and cover bloated fixedly connected of heat transfer tube pipe Noodles like heat sink of air conditioner with the heat transfer of heat transfer tube, when adopting this mode, inciding the interlobate direct sunlight of absorption just may repeatedly reflect between two blades, repeatedly absorbed, yet increased the absorption efficiency of thermal-arrest plate to solar energy., adopted a large amount of blades, not only assemble processed complex, work efficiency is low, and the surface area of this device rises significantly, the problem that will inevitably cause emissivity to rise significantly thus, make the gain of its efficiency of light absorption be offset by the drawback that heat scatters and disappears fast, according to prior art: the surperficial absorptivity of black coating is more than 95%, emissivity is usually more than 36%-40%, and the emissivity of general solar selective absorbing coating can reach below 16%, both differences are more than 20%, and do not consider because area increases the adverse effect to emissivity, through the difference of the gain ranging of absorptivity relatively and emissivity just as can be known, this method is difficult to the raising of generation collecting efficiency; In addition, going up increase significantly and will making that thermal capacitance significantly rises of blade volume, unfavorable to the raising of collecting efficiency; Moreover, even blade is connected to blade profile and cover bloated fixedly connected of heat transfer tube pipe Noodles like heat sink of air conditioner with the heat transfer of heat transfer tube, also will produce the reduction of heat transfer efficiency owing to the gap of transmission of heat by contact, as everyone knows, the temperature of heat pipe was far above blade during air-conditioning conducted heat, therefore, the heat pipe diameter owing to expanded by heating greater than the thermal expansion of vane hole make both closely contact conduct heat, and the blade volume of plate core is far away little with respect to heat pipe, therefore the back aperture of being heated becomes big, and contains the cold water that remains to be heated in the heat pipe, can not produce corresponding change in size in certain limit of temperature rise, therefore, must cause the serious decline of heat transfer efficiency.
In sum, the defective of prior art awaits overcoming.
