摘要
将复合抛物面聚光器(CPC)和热管平板式集热器相结合,研究了一种以平面形吸热板为接收器的CPC型热管式太阳能集热器.采用碘钨灯模拟太阳光辐射,在不同辐射强度下,对CPC型热管式太阳能集热器和普通热管平板式太阳能集热器的集热温度、瞬时效率、平均效率及平均热损系数等热性能进行了对比实验研究.研究结果表明:与普通热管平板式太阳能集热器相比,CPC型热管式太阳能集热器不但提高了集热温度和集热效率,而且降低了热损失.这一研究结果为太阳能集热器的进一步发展提供了有意义的参考.
In this research a heat pipe type solar collector with compound parabolic concentrator （CPC） was studied, in which CPC was applied to heat pipe flat-plate solar collector with a flat absorbing plate. By using iodine tungsten lamp light to imitate solar radiation, the experimental in- vestigations were conducted for a CPC heat pipe type solar collector and a common heat pipe flat plate solar collector in a room. Under different simulating radiation intensity conditions, the thermal performances comparison of the two types of solar collectors were carried out, including the fluid temperature in collectors, instantaneous collector efficiency, average collector efficiency and average heat loss coefficient. The results indicate that the CPC heat pipe type solar collector not only increases the fluid temperature in collector and instantaneous collector efficiency, but al- so decreases average heat loss coefficient compared with the heat pipe flat plate solar collector.
