Abstract:As a kind of green and clean energy, solar energy plays a significant role in green development. To use the solar energy efficiently, a solar collector with an inner-cooling vapor chamber was designed and manufactured. The solar collector consists of the inner-cooling vapor chamber which is used as the receiver, and the multi-stage concentrator which is combined the line-focus Fresnel lens (LFL) and the compound parabolic concentrator (CPC). In addition, the designing method of the compound parabolic concentrator was proposed, its accuracy and the reliability of the solar collector were verified through the optical simulation and experiments. The results of optical simulations and experiments show that the compound parabolic concentrator manufactured according to the designing method proposed in this paper can concentrate the sunlight efficiently, with an optical efficiency of 78.42%. In the experiments where the solar collector is sealed with a transparent plastic cover, the inner-cooling vapor chamber solar collector can efficiently absorb the radiated solar energy and the air heat in the greenhouse with a high thermal efficiency of 98.94%.
