Abstract
PURPOSE: To obtain a miniature and lightweight device without using a cooling fan by providing a cooling air guidance part, which blows air to a cooler, under a semiconductor device which is equipped under the floor of a vehicle and has a heating part at its upper part and a cooler at its lower part.
CONSTITUTION: Semiconductor device 2 is supported under vehicle floor 1 by using the support material. Under this device 2, heating part 7 composed of semiconductor element stack 5 and refrigerant airtight container 6 is provided and over it, cooler 8 is arranged and connected to heating body 7 via pipe 9. In this constitution, a refrigerant is circulated between heating body 7 and cooler 8 to cool device 2, and wind guidance boards 10A and 10B are provided which are perpendicular to running direction 3A or 3B of the vehicle horizontally and slanting toward cooler 8 vertically. Consequently, lower wind 1 high in velocity near rail 4 striks cooler 8 via guidance board 10A or 10B in the running direction, thereby improving cooling effects.
