摘要
主要介绍采用热管技术,提高传热效率来提高对太阳能的利用率,同时利用热管管壳内呈负压而降低工质沸点的特性,使低沸点介质能在太阳光的直接照射下即可蒸发,从而达到利用工质的汽化潜热高效利用太阳能的目的。主要对热管装置进行了设计与校核,并简要介绍了热管的原理和传热介质的选择;针对试验结果,进行了分析与改进,以期对太阳能更高效地利用,达到对室内供热的目的。
This study focuses on using heat pipe technology to improve heat transfer efficiency and the utilization of solar energy.While taking the advantage of negative pressure to reduce the boiling point of the working fluid so that the media can be boiled to ebullience by sunlight easily.And take the latent heat of vaporization to achieve the efficient use of solar energy purposes.The heat pipe device design and verification is mainly introduced,also the choosing principle of transfer medium.After analyzed to the experimental results,a more efficient method is put forward to achieve the purpose for indoor heating.
