The cooling of the high-power thyristor (HPT) in explosion-proof sbcll (EPS) used inmining pit has been a difficult problem for a long time. It has some spectal demands. According toheat pipe’s working principle, this paper introduced a kind of newly devcloped beat pipe radiatorSeveral HPT in EPS can be cooled by one beat pipe. In order to obtain the cooling and forced convection cooling , two dimensionless equations were obtained. This paper also studicd the refation between the surface temperature of HPT and the working electric current. The corresponding curvewas given out. Experiments shown that the beat pipe radistor introdued in this paper could effectively cool the HPT in EPS. It becomes a practical and valuable new technique.
