Abstract

The utility model relates to a support plate supported at the bottom end of a CPU fixing base. The plate body of the support plate bends and protrudes upwards to form an arc-shaped convex structure; athrough hole is arranged at the middle of the plate body; and the support plate can be fixedly combined at the lower side of a mainboard through a fixing subassembly of a radiator and is placed at the bottom end of the CPU fixing base. When fixedly combining and positioning the support plate, the top end of the plate body rests against the lower side of the CPU fixing base so as to enable the arc-shaped convex plate body to be pushed and propped to be plane under the the drive of the screwing of the screws of the fixing subassembly, so that restore force can be accumulated in the plate body,which balances the elastic restore force generated by a screw compression spring of the fixing subassembly, and the mainboard can remain plane, thus preventing downwards bending, deformation and damage of the mainboard when installing the radiator on the mainboard and furthermore ensuring the locking poundage between the radiator and the mainboard and avoiding the loss of the locking strength. Therefore, the support plate enables the radiator to be steadily fixed on the CPU fixing base of the mainboard.

Description

Be supported in the back up pad of CPU holder bottom

Technical field

The utility model relates to the back up pad of a kind of CPU of being supported in holder bottom, particularly relates to the supporting plate structure in a kind of CPU of being applied to fixed support field.

Background technology

Development and progress along with computer technology, CPU (central processing unit) frequency of operation is more and more high, the thermal value that is produced during the CPU operation is more and more big, also strict day by day for the CPU radiating requirements, and be radiating requirements in response to senior CPU, the present heat dissipation equipment of developing is promptly complicated more and have more weight.

Cooperation is referring to Fig. 5 and shown in Figure 6, it is that a CPU holder 21 is set on mainboard 20, this CPU holder 21 can be provided with wherein for CPU210, heating radiator 30 is set above CPU holder 21, this heating radiator 30 comprises a metal pedestal 31 and several heat pipe 32, on several heat pipes 32 stacked radiating fin is set, these metal pedestal 31 bottoms are pasted and are butted on the CPU210 top, this heating radiator 30 also has several spacers 311, and can wear spring 42 by the screw 41 of fixation kit 40 and be passed down through mainboard 20, and be positioned at CPU holder 21 bottoms at mainboard 20 downsides one bracing frame 50 is set, plate body 51 peripheries of this bracing frame 50 form wing plate 52, the fixed cover 43 of fixation kit 40 is set on wing plate 52, makes screw 41 threaded portions that wear to be screwed into fixed cover 43 downwards and located.

Above-mentioned heating radiator 30 is arranged on CPU holder 21 mainboard 20 on every side, the weight of this heating radiator 30 is butted on the CPU holder 21, and this heating radiator 30 is that screw 41 by fixation kit 40 wears spring 42 and penetrates spacer 311, mainboard 20 and being screwed in the fixed cover 43, in the process that screw 41 is screwing togather, back up pad 50 peripheries are pulling upwards, back up pad 50 middle top surfaces are butted on CPU holder 21 bottoms, add upper spring 42 back stretch pushing and pressing screw 41 by compression upwards, this locking force that screw 41 spiral shells are established and spring pushes back is quite big, generally speaking, approximately between 40～70 pounds, and cause the mainboard 20 around the CPU holder 21 to be bent upwards distortion easily, the flexural deformation of this mainboard 20 not only can damage mainboard 20, and because of mainboard 20 flexural deformations have absorbed the part locking force, make the loss of locking poundage, cause the locking force deficiency, in the prior art, major part all is that the intensity of strengthening back up pad reduces deflection, for example making reinforced ribs or flanging are gained in strength on back up pad, yet, unless being Utopian rigid structure, this back up pad can not produce distortion, otherwise, because of locking force causes the problem of mainboard 20 distortion unavoidable at last, and must be overcome improvement.

Summary of the invention

The utility model purpose of design is, the back up pad of a kind of CPU of being supported in holder bottom is provided, this support plate top surface has the upwards arc convex form of protuberance, and can be when stressed fixed, produce a back stretch at end face, and can the balance fixation kit screw togather strength, make mainboard can keep flat state, cause damage to avoid mainboard to be bent downwardly distortion, and can guarantee the CPU holder and the locking force of set heating radiator on it, avoid this locking force loss, and on the CPU holder that heating radiator is fixed in mainboard that can be stable, make heating radiator can give full play to its heat sinking benefit.

For reaching above-mentioned purpose, the utility model provides the back up pad of a kind of CPU of being supported in holder bottom, comprises a plate body, and this plate body forms the arc convex form that is bent upwards protuberance, and this plate body periphery has several fixed parts.

Design thus, make back up pad be consolidated in the mainboard downside and be positioned at CPU holder bottom, this back up pad periphery also can be by the locking of fixation kit, make the plate body top of back up pad can be resisted against CUP holder bottom, and drive the plate body of arc convex form with fixation kit, it is plane that it is pushed against into, the accumulation response force is butted on CPU holder bottom in plate body therefrom, and energy balance fixation kit is locked in the strength of back up pad periphery, to avoid mainboard after the heating radiator installing to produce being bent upwards distortion and to damage, so design of the present utility model, can guarantee that locking force does not lose, make stable being arranged on the CPU holder of heating radiator energy, and allow heating radiator can give full play to its heat sinking function.
