Description
DESCRIPTION SOLAR ENERGY PHOTO-ELECTRICAL-PHOTO-THERMAL INTEGRATED ASSEMBLY AND SOLAR ENERGY THERMOELECTRIC JOINT PRODUCTION SYSTEM THEREOF TECHNICAL FIELD The present invention relates to a thermoelectric joint production system. Especially relates to a solar energy thermoelectric joint production system. BACKGROUND ART Cold-thermo-electric joint production is a total energy system which integrates the heat-production (or refrigeration) with the power generation process based on the concept of utilization of energy in step. It can utilize different kinds of energy, the thermo power with high temperature and wider available energy can be used to generate electricity, while the low-grade thermo power with low temperature can be used to supply heat or freeze. Thus not only the utilization efficiency of energy is increased, but also the discharging of carbide and toxic gas is reduced, yielding good economic benefits and society benefits. The solar energy thermo-electric joint production system is realized by combination of photovoltaic battery with solar energy water heater, wherein, the transfer efficiency of the normal photovoltaic battery assembly is 5-18% in general, the transfer efficiency is low and the cost is high. And with the working temperature of the photovoltaic battery assembly is rising gradually, the photo electric transfer efficiency is reduced and the service life of the battery stack will be influenced. Therefore the actual use in this field is less in domestic and mainly in research area. If the photovoltaic battery is cooled in time, not only the excess heat producing in transfer process can be used effectively but also the photo electric transfer efficiency can be improved, thus the comprehensive utilization efficiency of the solar energy per unit area can be increased and the cost of photovoltaic and photo-thermo are reduced greatly, and is conductive to large scale promotion. 1 In addition, nowadays the middle-low temperature photo-electric and photo thermo technical products has a wide varieties at home and abroad, mainly can be divided into two kinds including air cooled type and liquid cooled type according to the cooling photovoltaic battery method. The photovoltaic battery of the air cooled type photo-electric and photo-thermo technique is cooled by natural convection or by assisted mechanical ventilation using the outdoor air. The liquid cooled type photo-electric and photo-thermo technique is based on the normal solar energy heat exchanger, by aprresing a piece of photovoltaic battery; the thermo-electric jointing supply is realized, it can be divided into pipe sheet type, wing pipe type, hosepipe type, flat box type and hot pipe type. Although the middle-low temperature photo-electric and photo-thermo technique has wide varieties, but all of them have their own shortcomings. The heat utilization efficiency of the air cooled type photo-electric and photo-thermo technique is very low. The main reason is that the thermodynamic property of air is poor. So this technique only can improve the photo-electric efficiency and solar energy general utilization efficiency very limitedly. And this technique is limited to the building ventilation system in some area, so the application range is small. Because the liquid (normally the medium is water, acetone, or ammonia et al.) has relative high thermodynamic properties, the heat utilization efficiency of the liquid cooled type photo-electric and photo-thermo technique is relative high in general. But this technique also has many shortcomings: the collector structure is complicated, the cost is high and the contact thermal resistance with photo-electric sheet is very big. Normally this technique need to use thermal silica gel or extra laser welding substrate or encapsulated substrate to solve the contact problem of the collector structure and the photo-electric sheet. In addition the rib efficiency of this kind of heat collecting structure is very poor (normally laying a pipeline at predefined intervals), and the flow resistance pressure (the pressure loss) of the working medium is high in general. Therefore in conclusion the improving capability of this technique for the photo-electric efficiency and solar energy 2 general utilization efficiency is also very limited and the large-scale promotion of the project is not suitable. Therefore the research and development of the solar energy thermoelectric joint production system which is simple and compact in structure, with high thermal efficiency and low pressure loss, and easy to promote is imperative. By searching the relevant documents, the solar energy thermoelectric joint production system technique solution of the present invention is not found.

Specifically the inner side of the corrugated thin plate is punch-formed with several mutually parallel arranged herringbone guide ribs from the inlet side to the outlet side and the flow passages of the guide ribs in adjacent lines are stagger arranged. Preferably, one end of the U-shaped elastic metal component which retains the thin plate-type heat exchanger is provided with a metal thin sheet. The thickness of the metal thin sheet is less than the thickness of the U-shaped elastic metal component. And the end outer surface of the U-shaped elastic metal component connected with the metal thin piece is flat with the outer surface of the metal thin sheet. Further a solar energy thermoelectric joint production system base on the said solar energy photo-electrical-photo-thermal integrated assembly is provided, the innovation point of which is in that: including a bracket, a solar energy photo electrical-photo-thermal integrated assembly, a working medium circulating system and a solar energy generating system. The solar energy photo-electrical-photo thermal integrated assembly is obliquely arranged on the bracket according to the altitude angle of the solar, the assembly includes a photovoltaic battery plate with a metal outer frame, and a metal thin plate-type heat exchanger and a heat preservation material layer sequentially parallel arranged at the back of the photovoltaic battery plate in an overlapped mode.

A working medium circulating system includes an insulated water tank, a coil pipe heat exchanger, a circulating pump, a medium inlet pipe, a medium outlet pipe. The coil pipe heat exchanger is provided in the insulated water tank. The liquid inlet end of the coil pipe heat exchanger is communicated with the medium outlet of the metal thin plate-type heat exchanger by the medium inlet pipe. The liquid outlet end of the coil pipe heat exchanger is communicated with the medium inlet of the metal thin plate-type heat exchanger by the medium outlet pipe. The circulating pump is provided on the medium outlet pipe and is powered by the solar energy generating system. The advantages of the present invention are in that: the metal thin plate-type heat exchanger is composed of two mutually parallel metal thin plates in an overlapped mode, one piece of the metal thin plates is provided with irregular corrugation surface. Unequal cross-section thin fluid passages are formed between the plates and exchange the heat directly with the back plate of the photovoltaic battery plate by the flow working medium. Because the heat exchanger is with a flat plate type structure and can be tightly attached with the back plate of the photovoltaic battery plate, the influence of the contact thermal resistance is removed completely. In the circumstance with same pressure loss, the coefficient of heat transmission is three to five times higher than the pipe sheet type heat collector structure and the rate of heat reclaim can be more than 90%. At the same time, the metal attaching clamp adopts the high strength metal as 6 aluminum alloy, stainless steel et al, is a molded U-shape elastic metal component by single-pressing, has good hardness, flexibility, tension characters and is corrosion resistant and anti-abrasive. The metal attaching clamp can fasten the metal thin plate-type heat exchanger between the side frame and back plate of the photovoltaic battery tightly, realizing the tight attachment between the heat transfer structure and back plate of the photovoltaic battery and realizing the purpose of modification from photovoltaic battery plate to photo-electrical-photo-thermal integrated assembly in work field directly, the cost is reduced. Without using any other attaching material in the whole contacting process, not only the extra heat resistance is reduced but also the manufacturing cost of the whole assembly is reduced. In addition, a metal thin sheet is provided at the front end of the U-shape elastic metal component which can press the metal thin plate-type heat exchanger better. Simultaneously, when disassembling due to the minor elastic deformation force of the metal thin sheet, it can be gripped fluently and it is convenient to disassemble by using the clamp tool et al. When the side frame and the back frame of the metal outer frame is formed integrally, in order to assemble fluently the metal thin plate-type heat exchanger is a little smaller than the photovoltaic battery plate, while the size of the heat preservation material layer can be same with the photovoltaic battery plate, and can be assembled by little deformation which is convenient and quick. When the metal outer frame is detachable, the metal thin plate-type heat exchanger, the photovoltaic battery plate and the heat-preservation material layer can be made with same size and the detachable structure is advantageous to modify the photovoltaic battery plate in prior art. Generally the corrugation is made by punching by stainless steel, aluminum, titanium or molybdenum thin plates et al. with a 0.5-3mm thickness and can be made according to any length-width size of the photovoltaic battery plate. And it has high coefficient of heat transfer, low pressure loss, high load bearing, is 7 corrosion resistant and simple with manufacture process and has high degree in standard production and low cost. The metal thin plate can be pressed into all kinds of shaped corrugation by using various different grinding tools, and four corner apertures are provided on the two corners of the corrugation piece to be as the inlet and outlet passages. The corrugation type of the metal thin plate mainly includes herringbone corrugation, straight bar corrugation, cross-straight corrugation, trapezoidal flat straight corrugation, ragged shape corrugation and bubble type corrugation et al. These corrugation designs constitute complicated fluid passages and make the work medium flow rotatably in three dimensional. The turbulence is formed with low Reynolds analogy parameter, so the heat-transfer coefficient of the heat collecting structure is relative high. The two thin plate pieces are welding formed by whole seal welding process (for example argon-arc welding) without using any non-metal seal material, so it is resistant to high temperature and high pressure and the range of temperature and pressure suitable to work is very wide. In addition, due to the thin plates are all made by metal punching, it has high degree of standardized manufacture, and the price of large-scale production is lower 40% 60% than the pipe plate type. The insulating material can reduce heat dissipated to the around circumstance of the metal thin plate-type heat exchanger, thus heat collecting efficiency is improved. The insulating material has the features that the coefficient should be small; the material is nonabsorbent and has certain hardness et al. The thickness of the insulating material is 3-5 cm. The common used insulating material includes polystyrene, polyurethane et al. The insulating material can be formed with apertures according to the different inlet-outlet pipe diameter of working medium. The photovoltaic battery plate of the thermoelectric joint production system outputs electric energy, the internal circulation of the metal thin plate-type heat exchanger flows the working medium, the heat transmission is completed with the photovoltaic battery and the heat is transferred to the insulated water tank; part electric energy generated by the system is used for driving the circulating pump to 8 work, the other part of electrical energy is used for interconnecting or be stored into the accumulator to meet extra electrical load.
