• a base plate;
• a heat source located on the base plate;
• a radiator in thermal contact with the heat source;
• and
• a fixing bracket located on the base plate, the fixing bracket comprising:
• a bracket body, one side of the bracket body having a first pivoting point and a second pivoting point;
• at least one connecting rod assembly, comprising
• a first rod having a third pivoting point and a fourth pivoting point, the third pivoting point being pivotally connected to the second pivoting point;
• a second rod having a first limiting part, a fifth pivoting point and a sixth pivoting point, the fifth pivoting point being pivotally connected with the first pivoting point;
• and
• a third rod having a second limiting part, a seventh pivoting point and a eighth pivoting point, the seventh pivoting point being pivotally connected with the sixth pivoting point, the eighth pivoting point being pivotally connected with the fourth pivoting point;
• and
• at least one elastic buckling arm located on the first rod, the connecting rod assembly driving the elastic buckling arm to move between a release position keeping a distance away from the radiator and a fastening position being against the radiator, wherein when the elastic buckling arm is located at the fastening position, the first limiting part is against the second limiting part.
