Description

The positioner of radiator

[Ji Intraoperative field]

The utility model provides a kind of positioner, more in detail, be applied on the radiator about a kind of, establish the relative position of backboard of central processing unit, so that make radiator be attached at positioner on the central processing unit quickly and accurately in order to fixed heat sink and group.

[Bei Jing Ji Intraoperative]

Along with the raising of central processing unit arithmetic speed, the power of its consumption and the heat of generation are more and more, thereby are having a strong impact on the performance and running stability of central processing unit.In order to ensure the normal operation of central processing unit energy, what industry adopted usually is that applying one is used to derive the heat abstractor of heat on central processing unit, and cooperates a fan on this heat abstractor that heat is derived.

The method of utilizing screw locking heat abstractor of prior art has following deficiency: when locking, the screw that screw must pass heat abstractor is fixed on the backboard of central processing unit, screw is difficult for aliging with center line of bolt hole and the application of force is difficult for, this heat abstractor easily rotation rocks so that the electronic component around damaging causes system normally to move; And may cause heat abstractor and central processing unit driving fit fully owing to pad is smooth inadequately, cause its sealed not tight situation, influence the radiating effect of this heat abstractor, and cause shaking the generation with noise.

In view of this, be necessary to provide a kind of positioner of radiator in fact, this positioner can be before assembling predetermined fixed radiator and the relative position of organizing the backboard establish central processing unit, and balance imposes on the sealed dynamics of radiator and backboard, so that quickly and accurately radiator is adhere well on the central processing unit.

[summary of the invention]

Therefore, the purpose of this utility model promptly provides a kind of positioner of radiator, in order to fixed heat sink and the relative position of organizing the backboard of establishing central processing unit, so that quickly and accurately the radiator button is fixed on the central processing unit.

For reaching above-mentioned purpose, the utility model provides a kind of positioner of radiator, the holding section of this positioner one end is mounted on the end face of radiator, the sleeved part of the other end is sheathed on the screw fixed leg of organizing on the backboard that is provided with central processing unit, to fix this radiator and this backboard relative position, and screw passes this positioner and cooperate this screw fixed leg easily this radiator to be locked on this backboard, make radiator attach on the central processing unit, for this central processing unit conducts heat.

Compared to prior art, the relative position of the utility model this radiator of predetermined fixed and this backboard before assembling, be solidified as a whole rapidly, exactly radiator and backboard are buckled, and the holding section of this positioner has disperseed to twist the degree of making a concerted effort when screw is locked, replaced the effect of pad, solved the pad out-of-flatness and bring sealed not tight disappearance.

[description of drawings]

Fig. 1 is the application state figure of the positioner of radiator of the present utility model.

Fig. 2 is the three-dimensional exploded view of the positioner of radiator of the present utility model.

[embodiment]

See also Fig. 1, that it disclosed is the application state figure of the positioner of radiator of the present utility model, as shown in the figure, one radiator 1 is covered on the backboard 3, the one side of these backboard 3 relative these radiators 1 is convexly equipped with several screw fixed legs 31, in order to sheathed motherboard (not illustrating) and radiator 1, and cooperate screw that this backboard 3 is buckled with radiator 1 to be fixed in the motherboard both sides, in addition, 3 of this radiator 1 and backboards are provided with a location device 2, the holding section 21 of this positioner 2 is mounted on the radiator 1, and the sleeved part 22 of this positioner 2 is sheathed on this screw fixed leg 31, to fix the relative position of this radiator 1 and this backboard 3.

See also Fig. 2, it is the three-dimensional exploded view of the positioner of radiator of the present utility model, the middle part group of the one side of the relative radiator 1 of this motherboard is established a bearing 32, and central processing unit 33 is mounted on this bearing 32 in the mode of pegging graft or weld, and should electrically connect with central processing unit 33 and this motherboard with order.

Moreover, this radiator 1 comprises a base 11, the bottom surface of this base 11 closely attaches this central processing unit 33 and is its conduction heat, and this base 11 end faces middle part extends and is some fins 12 that the square formation shape is arranged, and the screw fixed leg 31 of this relative backboard 3 in base 11 both sides is offered several location holes 13, sets position device 2 on this radiator 1 in order to group.

Again, this positioner 2 is a hollow cylinder, so that screw passes this positioner 2 and is locked on this screw reference column 31, and this positioner 2 comprises the holding section 21 of an end, the size of this holding section 21 is more bigger than these location hole 13 apertures, so that this holding section 21 is arranged on the end face of radiator 3, and the pore size of the external diameter of the sleeved part 22 of these positioner 2 other ends and this location hole 13 is roughly the same, and the size of the internal diameter of this sleeved part 22 and screw fixed leg 31 is roughly the same, so that sleeved part 22 is passed location hole 13 and is sheathed on the screw fixed leg 31, to fix the relative position of this radiator 1 and this backboard 3.

Please together consult Fig. 1 and Fig. 2, during assembling, earlier positioner 2 is combined on the radiator 1, wherein, the sleeved part 22 of this positioner 2 is passed the location hole 13 of the base 11 of this radiator 1, and holding section 21 is fastened on the end face of base 11; Then, radiator 1 is covered on the central processing unit 33, wherein, the sleeved part 22 of positioner 2 is sheathed on the screw fixed leg 31; At last, screw is twisted by this positioner 2 and is closed on screw fixed leg 31, so that radiator 1 is adhere well on the central processing unit 33.
