<p>PURPOSE:To increase wide usage in the installation of an air-conditioning machine and improve heat dissipating efficiency as well as the after service of the air-conditioning machine, by a method wherein the angle of fixing screws of an electric appliance setting metal is specified with respect to the direction of fixing screws for a heat dissipating plate. CONSTITUTION:A diode 11, a transistor 12 and the heat sensitive part 13 of a temperature sensor necessary for the protection, of electric appliance are fixed to predetermined positions by screws respectively while a heat dissipating plate 8 and an electric appliance mounting metal 10 are fixed by fixing screws 14 so that the mounting surface of the plate 8 and the contacting surface 10a of the metal 10 are contacted closely through adhesive agent. The contacting surface of both parts are not parallel but are slanted with respect to the axial center of the fixing screws 14 while a rounded part 10b, extended logitudinally, is provided at one end of the slanted surface of the electric appliance attaching metal 10 to secure a gap 15. The angle of the dissipating plate fixing screw 9 is deviated by 90 degrees with respect to the direction of the fixing screws 14 of the electric appliance metal fixture 10.</p> |
