Although the tsot heat exchanger has been successfully applied in the realm of heat - recovery in industrial boilers and furnaces , the mechanisms of tsot and its effects of some elements on its heat transfer features are unknown . reports about the tsot research have seldom seen . so it is not only urgent but also important to do some investigations on tost to enrich the heat pipe theory and guide engineering design 由侧端切向开漩流孔的半开式热虹吸管制成的热管换热器已在工业锅炉、窑炉中初步得到成功应用，但对其内部的机理和有关影响因素尚不十分清楚，在国内、国外文献资料中对该种热管的相关研究资料的报道也较少，因此，迫切需要进行相应的研究，以丰富热管理论并指导工程设计。
