太阳能电池板温控及优化实验研究

Experimental study on panel temperature control and optimization

在大空间自然对流的条件下,使用3种不同的被动式散热装置对太阳能电池板进行温度控制。在加装相变材料的散热装置的基础上,通过改变相变散热装置的相变材料种类、厚度和装置结构,进行对比实验研究。结果表明,具有相变材料的被动式冷却散热装置是可行的,材料上使用50 mm厚度的70#石蜡,结构上安装垂直于翅片的格栅能取得较佳的光电转化效率。

Three different passive heat dissipation devices are used to control the temperature of solar panels under the condition of natural convection in large space.On the basis of the heat dissipation device with phase change material,the type and thickness of phase change material and device configurations are changed.The results showed that passive cooling heat sink having phase change material is feasible,the use of the material thickness 50 mm paraffin 70#phase change material as a grid,a fin is mounted perpendicular to the structure can achieve higher photoelectric conversion efficiency.
