【摘要】 提出了对带反光板的吸热体接收太阳辐射量的分析方法 ,并对三种有渐开线反光板且吸热体形状不同的热管真空管和一种无反光板的热管真空管进行了对比实验。结果表明 :渐开线反光板可大幅度提高热管真空管的热性能 ,而且其吸热体的形状对热性能提高的幅度有影响更多还原

【Abstract】 The analytical method for studying heat absorption of absorbers with reflector was given,as well as conducted comparative testing on 3 heat pipe vacuum tubes with different shaped absorbers and CPC reflectors and one heat pipe vacuum tube without reflector. Results indicated that the CPC reflector can help improve thermal performance substantially,and also the shape of absorber has an effect on improving thermal performance.更多还原
