摘要
在能量平衡方程的基础上,以《家用太阳热水器热性能试验方法》(GB/T12915—1991)为依据,对两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热水器的日平均效率,加反光板且吸热体为圆柱形的集热器能够达到更好的效果。
On the basis of the energy balance equation, and household solar hot water heater performance test method （GB/T12915-1991 ） , comparative tests on heat pipe vacuum tubes with different-shaped absorbers and CPC reflector and one beat pipe vacuum tube without reflector were conducted. Results indicated that the CPC reflector can help improve average efficiency substantially, and the shape of absorber has an effect on improving average efficiency.
