摘要
热桥柱是热桥的重要组成部分,有必要就其传热影响区域展开专题研究。以重庆地区为例,通过有限体积法数值求解得出:热桥柱传热影响区域为其边缘两侧300mm范围,尤以150mm范围为甚;热桥柱边缘两侧300mm范围内做局部加强外保温时,能有效避免外侧保温层热桥柱连接处断裂导致的热损,且能基本消除室内侧热桥柱的漏热问题。
Thermal bridge column is an important part of the thermal bridge, it is necessary to research into its influence area of heat transfer. This paper takes a case in Chongqing area to be studied. The result shows that through numerical calculation numerical solution of the finite volume method, the in- fluence area of bridge column heat transfer is 300 mm around the column edge, and that within the 150 mm is greatly influenced. It can effectively avoid heat loss from the fissure of the heat insulation joint to bridge columns fracture. Meanwhile, it can also eliminate the heat loss form indoor thermal bridge column.
