摘　　要：本文介绍了新型槽式太阳能集热装置,着重对该集热装置集热性能进行了研究及分析,并对集热装置进行热性能试验,提出系统优化设计方案。结果表明该新型槽式太阳能集热装置具有较高的集热温度和较高的集热效率,闷晒工况下,集热介质温度可达190℃以上,循环工况下,53 kg集热介质温度最高可达115℃,瞬时集热效率最高可达36%。A new trough solar collector device was introduced in this paper. The heat collection properties of this device were analyzed and the thermal performance experiments Were also carried out to propose optimized design scheme of the system. The results show that this new trough solar collector device has a high heat collection temperature and efficiency. The temperature of heat collection medium can be above 190℃ under sunning conditions, in the other hand,the temperature and instantaneous heat collection efficiency of 53kg heat collection medium can be up to 115℃ and 36%, respectively, under circle conditions.
