ABSTRACT:
Disclosed is a bearing structure of a central processing unit comprises a radiating plate, a back plate, a plurality of screws and elastic elements. The radiating plate has a heat conductive portion and a plurality of sleeves. The back plate is installed below the radiating plate and has a plurality of studs. The plurality of screws are placed within the sleeves of the radiating plate, and protrudes from the bottom of the radiating plate. The plurality of elastic elements being installed between the screws and the sleeve. The radiating plate is moved by the elastic elements so that the heat conductive portion of the radiating plate presses elastically the central processing unit. Therefore, the pressure will not be too large so as to harm the central processing unit, or too small so as to cause the unfastening therebetween. As a result, during assembly, the fastening force of the screws would not be adjusted. Thus, the assembly work becomes easily and the cost is reduced.
