For realizing that above-mentioned purpose technical scheme of the present invention is that the said mounting bracket of employing is to be made up of connection gusset or connecting rod between several bosses and the boss; Said boss comprises boss that is connected with printed substrate and the boss that is connected with power device; The shape of said mounting bracket is set according to the position of the shape of said power device installed surface, power device installing hole on installation site on the said printed substrate and printed substrate; Said mounting bracket is used to connect said printed substrate and said power device, and said mounting bracket also is used for the said power device of roof pressure makes the heating surface of power device closely contact with radiating element; Said boss is a cylinder; The face that in the end face of said cylinder, is connected with said printed substrate or said power device is the plane; On said plane, be provided with installing hole, said installing hole is corresponding with the installing hole on said printed substrate or the said power device.
Wherein, several bosses connected into an integral installation support shown in said gusset or connecting rod were incited somebody to action, or several bosses connect into several mounting brackets shown in said gusset or the connecting rod general.
Wherein, said gusset also comprises the bearing rib that is used to support said power device.
Wherein, on said bearing rib, be provided with the projection that is used for fixing said power device location.
Wherein, said mounting bracket is to be processed by metal and/or plastics.
Wherein, said power device is the power device on the household electrical appliance.
Wherein, said printed circuit board (PCB) is the control board on the household electrical appliance.
Wherein, said radiating element is fixed on the casing.
Advantage of the present invention and beneficial effect are; Utilize mounting bracket that power device is pushed to radiating element, make radiating element and power device keep tight contact condition constantly, by bigger support contact area; Just can on radiating element, press the most area of device; Make its power device firmly on radiating element and seam can not occur sticking up, can well the guaranteed output device on same plane, realize well heat radiation.
