It is an object to provide a heat radiation system in which, even though there is variation in thickness among six switching devices, all of these devices can securely be adhered by means of a single fixing plate to a heat sink. <??>The fixing plate for fixing to a heat sink six switching devices U, X, V, Y, W, and Z arranged in a line on a printed board is made of a single metal plate to which forming processing has been applied, and has a base portion (11) formed being elongated in a direction in which the switching devices are arranged and three device-pressing portions (15) provided at one side of the base portion, in an elongated form being spaced apart form each other and being coupled through coupling portions (14) with the base portion, wherein the device-pressing portion has a width, in the longitudinal direction of the base portion, for pressing two of the switching devices as a pair, and has a through-hole (16) for a screw, formed in the middle of the longitudinal width thereof, for sandwiching the switching device between the device-pressing portion and the heat sink, and fastening the switching device to the heat sink; and wherein the coupling portion is formed so as to have a width smaller than that of the device-pressing portion so that the device-pressing portion can be moved obliquely against the heat sink. <IMAGE> <IMAGE> |
