Abstract
The invention relates to the field of solar energy heat utilization and especially to a solar photovoltaic photo-thermal integrated assembly equipped with double headers. The solar photovoltaic photo-thermal integrated assembly comprises a solar cell formed by a toughened glass layer, a transparent TPT material layer, an upper EVA material layer, a photovoltaic cell layer, a lower EVA material layer, and an opaque TPT material layer which are laminated from top to bottom, and is characterized by also comprising an upper header, a lower header, and a heat absorbing plate formed by triangular copper pipes. A water inlet and a water outlet are disposed on the vertex angle sides of the headers. The upper header communicates the openings of the triangular copper pipes with up-facing flat surfaces. The lower header communicates the openings of the triangular copper pipes with down-facing flat surfaces and is communicated with the upper header at a side opposite to the vertex angle of the lower header. A continuous bent copper sheet formed by two welded thin copper plate layers is arranged between the upper header and the lower header. The solar photovoltaic photo-thermal integrated assembly maintains the surface temperature of a photovoltaic cell panel within a stable temperature range. The copper heat absorbing plate achieves a heat absorbing effect and guarantees the service life of the solar photovoltaic photo-thermal integrated assembly.
Description
Technical field
The present invention relates to solar energy heat utilization field, particularly relate to band duplex box-type solar photovoltaic and photothermal integral assembly.
Background technology
Transform light energy is becoming in the process of electric energy by solar cell, is not all to convert whole luminous energy to electric energy.Theoretical research shows, the Theoretical Physics limit of the conversion efficiency of solar cell 0 DEG C time of one pole single crystal silicon material is 30%.Under the condition that light intensity is certain, when silion cell own temperature raises, power output will decline.In actual applications, under reference condition, crystal silicon cell average efficiency is about 15%.That is, the transform light energy of 15% can only be become available electrical energy by solar cell, and remaining 85% is all converted into heat energy.In transfer process, along with the increase of heat energy, battery temperature constantly raises, and except photoelectric conversion efficiency reduces greatly, the useful life of solar cell also will shorten.
Summary of the invention
The present invention is achieved by the following technical solutions:
Band duplex box-type solar photovoltaic and photothermal integral assembly, comprise by the toughened glass layer of lamination from top to bottom, transparent TPT material layer, upper EVA material layer, photovoltaic cell layer, lower EVA material layer, the solar cell that opaque TPT material layer is formed, it is characterized in that, also include upper header, lower collecting box, the absorber plate that triangle copper pipe is formed, header drift angle side is also provided with water inlet, delivery port, the mouth of pipe of flat triangle copper pipe is upward communicated with by described upper header, the mouth of pipe of flat triangle copper pipe is down communicated with by described lower collecting box, and be communicated with upper header at lower collecting box drift angle offside, said upper header be continuous folding copper sheet that two layers of thin copper coin welds between lower collecting box.
Further, described absorber plate is scale copper structure, and its thickness is less than 8mm, and the thickness of header is greater than the thickness of triangle copper pipe, and triangle copper pipe and the mode of communicating of header are that the part by exceeding is communicated with.
The good effect that the present invention has is:
The absorber plate of photovoltaic and photothermal solar integral component is arranged to duplex case structure by the present invention, water through water inlet first through lower collecting box to triangle copper pipe, arrive upper header again, flow out outlet pipe, the mode of this laminar flow heat absorption has following beneficial effect: 1. effectively slow down temperature in a day and, on the impact of photovoltaic battery panel, the surface temperature of photovoltaic battery panel is maintained in more stable temperature province and maximizes to reach transformation efficiency; 2. adopt copper absorber plate not only while meeting endothermic effect, and the useful life of the product ensured.
