FIG. 1 is an assembly perspective view of an embodiment of a radiator mounting bracket according to the present invention, FIG.
It is an installation perspective view. FIG. 2 is a plan view (A), a front view (B) and a side view (C) of the fitting. The mounting bracket 1 is manufactured by bending one metal piece. First, a part of the metal piece is cut and bent at a substantially right angle to the base portion 1a to form the first supporting surface 1b. A second support surface 1d is provided by extending the remaining part of the metal piece to the base portion 1a and bending the tip of the extended portion 1c at a substantially right angle to the extended portion 1c. Between the first support surface 1b and the second support surface 1d, a number of heat dissipation fins 2c, 2c of the radiator 2 having a plurality of fins (heat dissipation plates) 2c, 2c, ... Hold in. Note that when holding the heat radiation fins 2c, 2c between the first support surface 1b and the second support surface 1d, the tip portions of the first support surface 1b and the second support surface 1d are preliminarily separated from each other. Set the spacing slightly close to each other, and hook one support surface to the heat radiation fin to rotate the mounting metal fitting around the same point as the fulcrum so that the other support surface sandwiches and holds the heat radiation fin. 1, the radiation fin 2 can be stably held. A leg portion 1e provided on the other side of the base portion 1a of the mounting member 1 holding the radiator 2 is inserted into a hole formed in the circuit board and fixed to a conductor foil of the circuit board by soldering or the like. A radiator plate of a transistor is screwed into the screw hole 2b formed in the base portion 2a of the radiator to operate as a radiator. Note that such a configuration is particularly effective when the circuit board is used upright, because the radiation fin surface can be made vertical and the air convection is assisted to improve the heat radiation effect.
