光伏热效应实验单元散热及余热利用实验研究

Experimental Study of Heat Dissipation and Waste Heat Utilization on Photovoltaic Thermal Efficiency Experimental Platforms

利用搭建的5个光伏热效能实验单元,研究了光伏组件不同散热方式对光伏组件表面温度、建筑室内温度及发电功率的影响,同时利用空气的热压作用实现了光伏余热的直接利用。实验表明被动式外循环模式散热效果最好,开缝模式散热效果最差,被动式内循环模式余热利用效果较好。

Using five photovoltaic thermal efficiency experimental platforms,the effects of different heat dissipation methods of photovoltaic modules on the surface temperature,indoor temperature and power generation are studied.At the same time,the direct utilization of photovoltaic waste heat is realized by hot pressing action of air.The experimental results show that the passive external circulation mode has the best heat dissipation effect,the slotted mode has the worst heat dissipation effect,and the passive internal circulation mode has a good waste heat utilization effect.
