Description

The cpu heat fixed sturcture

Technical field

The utility model is a kind of fixing structure of radiator about CPU, and this fixed sturcture makes living good the connecing to effect of production capacity between heating radiator and the CPU, effectively the heat energy that CPU produced is shed in order to heating radiator.

Background technology

CPU is in order to carry out computing and huge data to be carried out the core component of high speed processing in the computing machine, because CPU constantly promotes on the demand of arithmetic speed advancing year, also therefore, frequency of operation constantly improves, and CPU is when arithmetic speed promotes, the hear rate that it produced also with lifting, the heating radiator that therefore needs great heat radiation effect comes CPU is dispelled the heat, with prevent CPU because of overheated can't normal operation or even the situation of damage takes place.

At present in the enforcement about the CPU heat radiation, be to connect to heat conductor on the CPU surface, this heat conductor is made of the copper with radiating fin or radiating tube, aluminium or the high metal material of other thermal conductivity mostly, and cooperates a fan to force blowing to combine a cpu heat to this heat conductor; Certainly, can impose thermal grease or heat radiation paster between heat conductor and the CPU surface filling up the slit that contacts therebetween, and strengthen thermal conduction effect therebetween.

Aforesaid enforcement, with heat conductor the heat energy that CPU was produced is derived, and cooperate the command of execution flow air molecule of doing of fan to contact with heat conductor, with the radiating effect of further quickening heat conductor, this kind radiating mode is the mainstream technology that meets economic benefit now in the CPU heat dissipation technology most.

Can learn by above stated specification, the key factor that influences CPU heat radiation is the flow rate that area of dissipation and the fan for heat conductor causes air molecule, disengage the problem that heat energy rises in order to meet CPU processing speed quickening in recent years, the shared volume of heat conductor and fan, space design also gradually with increase, the problem that also causes heatsink weight and volume to increase.

Generally speaking, the locator meams of heating radiator is the suitable position that directly is fastened on CPU slot periphery by an elastic spring or cramp, makes heating radiator that CPU is produced a strength that compresses relatively, so that heating radiator is fixed.But, the CPU slot is not to design for powerful holding capacity can be provided on structural design, this kind is with the mode on the direct fixation of C PU slot of heating radiator, limited for the anchorage force that the bigger heating radiator of volume and weight can provide, and between fixing vibration, heating radiator and CPU also can cause fan running when bad the time improper friction, the uneven impartial problem of CPU pressurized take place, and when computing machine in when carrying, the weight of heating radiator can produce the improper application of force to the CPU slot, and then easily the CPU slot is caused damage.

For anchorage force preferably can be provided, known technology is corresponding to CPU slot periphery several perforation to be set on motherboard, and with a posting after directly locking or button are located at motherboard, cooperate other buckling component that heating radiator is withheld on CPU again, the acting force that this kind enforcement is produced in the time of heating radiator can being provided with directly is scattered on the motherboard, to improve the improper stressed situation of aforementioned CPU slot.

Only, directly provide the heating radiator anchorage force with CPU slot or motherboard in the known technology, but between CPU slot and the motherboard or motherboard inside still has many accurate connected circuits, therefore on holding capacity, still can't effectively promote, and in the process of assembling heating radiator, cause the damage of various connected circuits easily.

The utility model content

The purpose of this utility model is to provide a kind of cpu heat fixed sturcture.

Two by aforementioned button hole and screw fixed hole with backboard and the solid bolt of stator spiral shell.

The end that described cpu heat fixed sturcture, wherein Z-shaped buckle ear are provided with button hole is horizontal by a slanted angle before not being subjected to the bolt bolt solid.

Described cpu heat fixed sturcture, its middle frame bottom surface is provided with the fool proof salient point.

Described cpu heat fixed sturcture is provided with an insulation course between its dorsulum and the motherboard.

Described cpu heat fixed sturcture, wherein screw fixed hole is located in the protruding bolt of backboard, and protruding bolt is gone into perforation and is protruded from the motherboard surface from main frame backboard side.

Described cpu heat fixed sturcture, its dorsulum is provided with the depressed area of evading CPU slot leg.

Described cpu heat fixed sturcture, wherein the depressed area is provided with open-work.

Specifically, cpu heat fixed sturcture of the present utility model comprises at least: two perforation of being located at motherboard cpu slot periphery; One is located at the backboard of motherboard dorsal part, and this backboard is provided with two screw fixed holes corresponding with aforementioned perforation; One is fixed at the stator of heating radiator bottom, this stator further comprises a framework and two Z-shaped buckle ears of being located at the framework both sides and extending downwards, this framework centre has empty part and exposes correspondingly with CPU for the heat-conducting part of heating radiator bottom, and it is corresponding with the default perforation of motherboard that the end of aforementioned Z-shaped buckle ear is provided with button hole; And two by aforementioned button hole and screw fixed hole with backboard and the solid bolt of stator spiral shell.Make stator directly be connected locking with backboard according to this, that is caused when avoiding heating radiator that motherboard is directly locked may damage, and makes and form a complete stress structure between stator and the backboard.

Wherein, the end that aforementioned Z-shaped buckle ear is provided with button hole is horizontal by a slanted angle before not being subjected to the bolt bolt solid, when Z-shaped buckle ear is subjected to the bolt locking, bolt can be oppressed the end of Z-shaped buckle ear, this moment, the end of Z-shaped buckle ear can provide a reverse elastic resistance, made bolt be not easy to get loose in screw fixed hole because of vibrations according to this.

Secondly, the framework bottom surface can be provided with the fool proof salient point, when the purpose of design of this fool proof salient point is to prevent that stator is installed in the heating radiator lower end, because of artificial careless mistake causes stator to be reversed to assemble when causing subsequent installation situation to the improper compressing of CPU.

Moreover because the motherboard that partly label produced is because of manufacturing technology difference to some extent on the market, so can convex with leg in the motherboard dorsal part in the CPU slot, therefore, the utility model is can be provided with on backboard in order to evade the depressed area of CPU slot leg; Perhaps, can put an insulation course between backboard and motherboard, this insulation course and has the function of buffering except the effect with insulation, and can utilize the difference of thickness of insulating layer simultaneously and adjust locking spacing between stator and the backboard.

Person more, aforementioned screw fixed hole is located in the protruding bolt of backboard, and this protruding bolt can be gone in the perforation and protrude from the motherboard surface from main frame backboard side, makes stator when locking more convenient to bit motion.

The effect that the utility model is promoted is: be locked in motherboard by the stator that is arranged between heating radiator and the CPU, can make that heating radiator can be firm with CPU produce connect to, the heat energy that makes CPU produce effectively conducts on the heating radiator.
