Abstract
The invention provides a locomotive power module air-cooling heat-dissipating device comprising a substrate. A power element is fixedly disposed on the surface of a side of the substrate. A heat-dissipating fin group used for dissipating heat is disposed on the other side of the substrate. At least two heat pipes with heat-conducting capabilities better than that of the substrate are buried in the substrate. One end of each heat pipe is arranged in a projected area, on the substrate, of the power element. The other end of each heat pipe is arranged outside the projected area, on the substrate, of the power element. According to the locomotive power module air-cooling heat-dissipating device provided in the invention, the heat pipes transfer heat in an area, with much heat, on the substrate of the heat-dissipating device to an area, with less heat, on the substrate of the heat-dissipating device in order to balance the temperature of the electrode board of the heat-dissipating device. Then, the heat is dissipated by the heat-dissipating fin group such that the heat-dissipating capability of the substrate is improved. Therefore, the heat of the power element is fast dissipated and the heat-dissipating efficiency of the heat-dissipating device is increased.
