Description
Technical field
The present invention relates to a kind of cascade utilization device of solar energy, particularly relate to the electrothermal combined using device of solar cell.
Background technology
The extensive utilization of following solar energy is to be used for generating, realizes by replenishing the transformation of the energy to alternative energy source.Its basic principle of opto-electronic conversion is to utilize photovoltaic effect that solar radiant energy directly is converted to electric energy, and its basic device is a solar cell.The major obstacle of the large-scale promotion application of solar cell generating at present is that cost is higher.
Solar cell is along with the rising of temperature, and efficient can descend.So how the unconverted solar radiation heat for electricity of solar cell effectively being taken away is a problem.At present, photronic radiating mode is divided into active and passive type.The heat that solar cell array produces directly is dispersed in the atmosphere by radiator, and this radiating mode cools off passive type.This mode is fairly simple, but about 80% the solar heat that battery surface is accepted is lost in the atmosphere, both can produce thermal pollution, can waste resource again.The heat that active cooling produces when being meant and with the water that flows or other medium concentrating component being worked is taken away, to reach the purpose of cooling solar cell.Active cooling can reduce the temperature of solar cell better, and, when utilizing this method, if the solar radiant heat of fluid removal is used, then can better realize the cascade utilization of solar energy, improve efficiency of energy utilization, can reduce the cost of solar power generation simultaneously indirectly.
At present the active cooling method of solar cell has liquid to soak mode and backboard heat-conducting mode, just has only the backboard heat-conducting mode in conjunction with the device of electrothermal combined using, by welding copper pipe behind at assembly, adopts air, water as taking hot working fluid.But this combination, owing to there is the non-conductor of heat in the solar module, little between heated body and solar cell backboard in conjunction with heat transfer area, heat transfer efficiency is low, the cost height.Present liquid boshing is mode but, because liquid flow control problem, the battery heat-transfer effect is not so good, and the inhomogeneous of Temperature Distribution produced influence to battery efficiency.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of electrothermal combined using device of solar cell is provided.The present invention can form thin layer heat transfer liquid film in solar battery surface in use, improves the heat transferred performance, and control photocell surface-stable is even.
