Abstract
The present invention relates to a high power device and a pressure-mounting method of a heat radiator of the high power device. Power devices and heat radiators thereof in a group are all mounted in tandem type, and the power devices and the heat radiators are alternately arranged in tandem arrangement. Every two adjacent devices are connected by a positioning pin, and all the devices connected in series are fastened together by an elastic adjustable screw bolt pressure-mounting fixing mechanism. The elastic adjustable screw bolt pressure-mounting fixing mechanism is composed of an end top plate, a front gland, an elastic screw bolt adjustment mechanism. One end of an adjusting screw bolt is fixed to an adjusting plate, and the other end of the adjusting screw bolt lies against a fixing plate. Adjusting each adjusting screw bolt uniformly can increases the pressure of a spring for pressing the front gland, so that the pressure-mounting force of the whole device connected in series can be increased. If different adjusting nut are adjusted respectively, adjusting the stress direction of the spring to the front gland can ensure that each pressure-mounting surface of the devices connected in series can be stressed uniformly. In addition, the end top plate and the front gland are both made of insulation material.
