On, solar radiation energy-flux density is improved to improve photoelectric transformation efficiency and then reduce cost.And that of electric energy can not be converted to
Portion of energy is lodged in converter in the form of being vibrated with photon, that is, so-called heat energy.Can by the second law of thermodynamics
It is relevant with the temperature of converter to know energy conversion efficiency, i.e., the open-circuit voltage of solar cell can drop as battery temperature is raised
It is low.The heat dissipation problem of Condensation photovoltaic battery is to influence the key factor of photovoltaic cell performance and system reliability, therefore in design
During concentration photovoltaic system, it is necessary to consider battery heat dissipation problem.
Traditional Condensation photovoltaic battery cooling mode has:Air-cooled, water cooling, microchannel cooling, heat pipe cooling etc..It is air-cooled
Technology is to increase fin in panel backside, although technique is simple, but radiating effect is limited;Biography of the heat transfer property of water than wind
Hot cold good, natural water cooling radiating effect is also better than air-cooled, but additionally to consider seepage and maintenance safety between working medium
The problems such as;Microchannel cooling is widely used in terms of electronic product cooling, but its complex process and extra blower fan power consumption is big;
Although heat pipe heat exchange property is good, working medium must match with heat pipe tubing, and heat pipe cooling cost height also causes it not
It is adapted to large-scale application in concentrating photovoltaic power generation industry.Therefore, a kind of low cost is found and cold with good heat exchange property
But method is very important.
