Technical Field
The utility model belongs to the technical field of solar collector, be a solar collector particularly.
Background
The efficient utilization of solar energy is one of effective ways to solve the problems of energy shortage and environmental pollution. At present, solar photovoltaic and photothermal utilization technologies are becoming mature. However, the subsequent development of the solar industry is restricted by the problems of low radiation density, instability, high cost and the like of solar energy, the light-gathering technology can enable the photovoltaic cell to output more electric quantity per unit area, the defects are effectively relieved, and the utilization rate of the solar energy in the area with weak illumination intensity is improved. The linear Fresnel lens is low in cost and easy to install, and can meet the actual requirements of small-sized family users.
The efficiency of a commercial monocrystalline silicon battery can reach 15% -18% under standard test working conditions, and most of the rest energy is converted into heat. However, due to the limitation of the silicon material, the electrical efficiency of the photovoltaic cell gradually decreases as the temperature of the photovoltaic cell increases, the temperature of the photovoltaic cell is increased more obviously by the light condensing device, the electrical efficiency is decreased rapidly, and meanwhile, the service life of the photovoltaic cell and the whole heat collecting device is shortened by the long-time high-intensity radiation. Adopt different cooling medium (like water or air) to cool off photovoltaic cell, produce low-grade heat again when can improving the generating efficiency, compare with the device of utilizing light heat and photovoltaic alone, saved installation cost and space, improved energy utilization, increase the operating life of whole device. And the flat plate type heat collector saves the production cost, is easy to be integrated with a building, and can meet the requirements of modern building development.
The absorber plate and the cooling runner in traditional photovoltaic light and heat integration solar collector adopt the tube sheet formula structure more, the mode that copper absorber plate and circular runner are connected promptly, and this kind of connection adopts welding process more, if the thickness of copper absorber plate is too thin, easily breaks through the deformation in the welding process, if thickness is too thick, has influenced thermal transmission again, and this kind of tube sheet formula structure requires highly to welding process, and the processing difficulty, influences beautifully. On the other hand, the actual contact area of the heat absorbing plate and the flow channel is close to line contact, the heat exchange area is too small, the total heat resistance is too large, the heat transfer is influenced, and the thermoelectric conversion efficiency of the whole system is reduced. Meanwhile, the heat absorbing plate and the circular flow channel are made of copper, so that the initial investment cost is high. Therefore, a new flow channel structure design is needed, the problem of the connection mode between the flow channel structure and the heat absorbing plate is solved, the heat exchange between the cooling fluid and the heat absorbing plate is enhanced, and the photoelectric and photothermal conversion efficiency of the whole device is further improved. The solar energy collector is convenient to process, low in cost and easy to manufacture and produce in a large scale, and the commercial development of the photovoltaic and photothermal integrated solar energy collector is promoted.
