But the pressure section of above-mentioned fastener 12 is firm with radiator 5 combination defective tightness, is easy to slide the groove 6 of radiator 5 in, causes radiator 5 fixing insecure and influence the effect that contacts with central processing unit.So this structure remains further to be improved.
[summary of the invention]
The purpose of this utility model is to provide a kind of heat abstractor combination of detaining the solidus shape fastener that keeps steady that has.
The purpose of this utility model is achieved through the following technical solutions:
Heat abstractor combination of the present utility model is used for being installed on the heat-generating electronic elements surfaces such as central processing unit on the motherboard, and it is dispelled the heat, and it comprises a radiator and two fasteners.This radiator has a pedestal, on this pedestal has, lower surface, its lower surface is the plane, fit with electronic component, its upper surface is provided with some radiating fins, place, the relative both sides of the edge of this radiator is provided with an accommodation space, above-mentioned fastener is to be formed by metal wire rod one bending, it comprises two operating portions that are embedded the supporting part in the radiator accommodation space and fasten with the fixed structure of electronic component location about setting on motherboard, this supporting part is bent to form the certain angle of tool, and this two operating portion is to be stretched out obliquely respectively by the supporting part two ends to form.
The utility model is compared with prior art has following advantage: because two fasteners of the present utility model pass through its rubber-like supporting part respectively in the fastening embedding accommodation space in radiator both sides, supporting part is extruded and produces elastic-restoring force, thereby support radiator, reach and radiator strong bonded in advance, when fastener is fastened on fixed structure, the relative changing of the relative positions can not take place with fastener in radiator, guaranteed that radiator fixedly secures on central processing unit and with its tight contact.
With reference to the accompanying drawings, the utility model will be further described in conjunction with the embodiments.
