Abstract
The utility model discloses a CPU radiating fin, which is characterized by comprising an H-shaped plate radiating fin body, wherein four corners of the radiating fin body are respectively provided with a through hole, and each of the through holes is fixedly connected with a fastener with an internal thread. The radiating fin is connected to a PCB (printed circuit board) through the fasteners with the internal thread, thereby being convenient to disassemble, meeting a requirement of interchangeability, and not influencing the connection strength because of heating.
Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to the fin 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 operating frequency, also will improve the requirement of fin.
Fin of the prior art is to wait the mode of being fixedly connected with to be connected on pcb board by welding, and this mode is dismantled inconvenience, and junction is subject to thermally labile, the phenomenon such as likely cause thawing, come off.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of convenient disassembly and is subject to heat-staple fin.
For addressing the above problem, the utility model provides a kind of CPU radiating fin, it is characterized in that, comprises work shape plate-shaped fin main body, described heat sink body is equipped with a through hole on four angles, all is fixedly connected with a securing member that is provided with internal thread on each described through hole.
As further improvement of the utility model, described securing member is rivet, and it is riveted on described through hole.
As further improvement of the utility model, described rivet is flower tooth rivet.
As further improvement of the utility model, described heat sink body is other being equipped with for distinguishing the indentation of described through hole of each described through hole of one side wherein.
As further improvement of the utility model, described indentation is respectively " 1 ", " 2 ", " 3 ", " 4 ".
As further improvement of the utility model, the another side on described heat sink body also is provided with a spatial accommodation snapped in for holding described cpu chip.
The beneficial effects of the utility model are, by the securing member that is provided with internal thread, fin are connected on pcb board, are convenient to dismounting, meet the interchangeability requirement, and can not affect because being heated its bonding strength.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is upward view of the present utility model;
Wherein: the 2-heat sink body; The 4-securing member; The 6-indentation; The 8-spatial accommodation; The 10-through hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As Figure 1-3, the utility model comprises work shape plate-shaped fin main body 2, and heat sink body is equipped with a through hole 10 on 2 four angles, all is fixedly connected with a securing member 4 that is provided with internal thread on each through hole 10.This securing member 4 is rivet and is flower tooth rivet.Heat sink body 2 wherein each through hole 10 side of one side is equipped with the indentation 6 for distinguishing through hole 10.Indentation 6 is carved with respectively " 1 ", " 2 ", " 3 ", " 4 ".
Another side on heat sink body 2 also is provided with a spatial accommodation 8 snapped in for holding cpu chip.
Operation principle of the present utility model is as follows:
One, cpu chip is embedded into heat sink body 2 wherein the one side spatial accommodation 8 in.
Two, radiating tube is welded on the another side of heat sink body 2.
Thereby three, in screw and flower tooth rivet, screw-internal thread fit is connected to heat sink body 2 on pcb board.
This mode, be connected to fin on pcb board by the securing member 4 that is provided with internal thread, is convenient to dismounting, meets the interchangeability requirement, and can not affect because being heated its bonding strength.
Above-described embodiment is preferably execution mode of the utility model; but execution mode 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 range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claim was defined.
Claims (6)
