Abstract
The utility model discloses a novel heat dissipation sheet applied to a CPU. The novel heat dissipation sheet comprises a square plate-shaped heat dissipation sheet body, and a plurality of heat dissipation fins are vertically arranged on the upper surface of the heat dissipation sheet body. The novel heat dissipation sheet is characterized in that four side surfaces of the heat dissipation sheet body are all equipped with long stripped clamping portions that extend downwardly, and each clamping portion includes a neck which is small in the middle and wide in two edges in a width direction. The heat dissipation fins are clamped inside grooves that are preset on a mainboard and are identical to the clamping portions in shape through the four clamping portions disposed on the heat dissipation sheet body. Each clamping portion is equipped with a neck that is small in the middle and wide in upper and lower, and the lower part of the neck is large in width, such that when clamped into the grooves, the clamping portions are not liable to disengage from the grooves and then joint strength between the heat dissipation sheet body and the mainboard is further improved. According to the above way, no screws are needed to screw the heat dissipation fins one by one, so the combination workload can be effectively reduced and the work efficiency of the heat dissipation fins is improved.
Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to the heat radiator that a kind of computer CPU is used.
Background technology
In recent years, along with the transfer capability of power circuit constantly increases, power consumption increases thereupon, therefore various electronic components have also produced very huge heat, brought heat dissipation problem, produced heat abstractor thereupon, with regard to current CPU element, the raising of its integrated level and frequency of operation, also will improve the requirement of heat radiator.
In prior art, be that the securing member by screw and so on is fixed on heat radiator on mainboard, this mode fixedly time, all needs manually to be screwed at every turn, and workload is larger, and production efficiency is low.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of can effectively coming down to a lower group and closes workload, the heat radiator of increasing work efficiency.
For addressing the above problem, the utility model provides the radiating fin in a kind of CPU of being applied to, comprise square tabular heat sink body, the upper surface of described heat sink body is vertically provided with some radiating fins, it is characterized in that, four sides of described heat sink body are equipped with the strip holding section to downward-extension, described holding section also comprise one in the middle of Width is the neck of little two hem widths.
As further improvement of the utility model, described neck below is provided with free end, and described free end width diminishes from top to down gradually.
As further improvement of the utility model, described neck below is provided with free end, and described free end inwardly folds and becomes obtuse angle with described neck.
As further improvement of the utility model, described radiator body is that aluminum alloy materials is made.
As further improvement of the utility model, described free-ended end angle is fillet.
The beneficial effects of the utility model are, by four holding sections that are arranged in heat sink body, heat radiator is fastened on default and mainboard, and identical with the shape of holding section inside grooves, because little in the middle of holding section is provided with, upper and lower wide neck, after holding section snaps onto in groove, because the width of neck below is larger, holding section is difficult to depart from this groove, and then increased the strength of joint between heat sink body and mainboard, adopt in this way, without using screw, tighten one by one, can effectively come down to a lower group and close workload, the heat radiator of increasing work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 2-heat sink body; 4-radiating fin; 6-holding section; 8-free end; 10-neck.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As described in Figure 1, the utility model provides the radiating fin in a kind of CPU of being applied to, comprise square tabular heat sink body 2, the upper surface of heat sink body 2 is vertically provided with some radiating fins 4, it is characterized in that, four sides of heat sink body 2 are equipped with the strip holding section 6 to downward-extension, holding section 6 also comprise one in the middle of Width is the neck 10 of little two hem widths.
By four holding sections 6 that are arranged in heat sink body 2, heat radiator is fastened on default and mainboard, and identical with the shape of holding section 6 inside grooves, because little in the middle of holding section 6 is provided with, upper and lower wide neck 10, after holding section 6 snaps onto in groove, because the width of neck 10 belows is larger, holding section 6 is difficult to depart from this groove, and then increased the strength of joint between heat sink body 2 and mainboard, adopt in this way, without using screw to tighten one by one, can effectively come down to a lower group and close workload, the heat radiator of increasing work efficiency.
Neck 10 belows are provided with free end 8, and free end 8 width diminish from top to down gradually.Adopt this structure, reduced the resistance that insert in groove holding section 6, be conducive to convenient being inserted in groove in holding section 6.
Neck 10 belows are provided with free end 8, free end 8 inwardly folding and with 10 one-tenth obtuse angles of neck.Adopt this structure, can further prevent that holding section 6 from departing from this groove, improved the intensity that heat sink body 2 is connected with mainboard.
Radiator body is that aluminum alloy materials is made.Because aluminium has good thermal diffusivity, adopt aluminium alloy, not only effectively inherited the good thermal diffusivity of aluminium, and with respect to metallic aluminium, intensity is better.
The end angle of free end 8 is fillet.Be set to fillet, prevent scratch groove, reduce the stress of free end 8 ends.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify and all should be equivalent substitute mode, within being included in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
