全玻璃真空管太阳集热器尾架和框架的改进

IMPROVEMENTS ON THE FRAME FOR “WATER IN GLASS” MANIFOLD OF ALL GLASS EVACUATED TUBULAR COLLECTORS

讨论了原有全玻璃真空管太阳集热器尾架和框架的不足，对新设计尾架和框架的刚度及强度进行了分析，并作了加载试验，表明它能承受０．４５ Ｍ Ｐａ

The new end supports for “water in glass” manifold of the all glass evacuated tubular collectors have been designed and tested on the basis of the calculation and experiments of the mechanical behavior of the original end supports and frame.The new end supports and frame with better stiffness and strength are able to withstand the water pressure of 0.45MPa.
