FIXING STRUCTURE OF POWER ELEMENT TO HEAT DISSIPATING MEMBER

摘要

PROBLEM TO BE SOLVED: To transfer heat from power elements effectively to heat dissipating fins of a heat dissipating member. SOLUTION: Fixing support 41 are installed on at least both sides of the heat dissipating member having many heat dissipating fins on the upper surface. A spring plate material 37 and the power elements 29 are installed on a circuit board 35. When the spring plate material 37 is engaged with the fixing supports 41 of the heat dissipating member 5, the power elements 29 are fixed with pressure on the rear 5a of the heat dissipating member 5 by the spring plate material 37.
