The Research On The Natural Convection Cooling For Photovoltaic Solar Cell

The system on the natural convection cooling for photovoltaic solar cell is studied widely,but the research is at the surface.At present,there is short of some important parameters about the application of different forms of the system on natural ventilation cooling for photovoltaic solar cell,such as the temperature of battery plate and the output power,the generating performance of each system is also a lack of analysis and research.This paper,aiming at the thermal properties of the heat transfer process with the system on natural ventilation cooling for photovoltaic solar cell and the influence of the battery temperature on the power generation performance,carry on comprehensive quantitative analysis and research.Firstly,set up the physical models and mathematical models of different system on the natural convection cooling for photovoltaic solar cell,determine the specific boundary conditions.Then use the FLUENT software to carry on simulation calculation of each cooling system of different outdoor temperature,different wind speed and different solar radiation,obtain numerical solutions of the temperature of the photovoltaic solar cell influenced by various factors.Through analysis the velocity and temperature chart about each cooling system,get the temperature distribution of the cooling system for photovoltaic solar cell and get different heat dissipation effect.Finally,through setting up the experiment platform of the cooling system for photovoltaic solar cell,test the battery temperature and output power of different cooling types of the photovoltaic solar cell,prove the possibility of each cooling system.Comparing the numerical simulation and the battery temperature by experiment measurement,drawing the figure about the average temperature of test points and the output power of photovoltaic panels,and then calculate and compare the daily cumulative power generation of different cooling systems in different seasons.experiment test,provide the data and theory reference in the aspect of design,construction and operation maintenance for the different system on the natural convection cooling for photovoltaic solar cell,and lay the reliable basis for its future application promotion.
