Description

The stand structure of central processing unit radiating module

[technical field]

The utility model relates to a kind of stand structure of central processing unit radiating module, refers to a kind of stand structure that promotes the runners bulk strength and guarantee central processing unit running smoothness especially.

[background technology]

The computing of computer and running are mainly finished by central processing unit (CPU) 1, yet along with the speed of central processing unit 1 running is more and more faster, the caloric value of central processing unit 1 is also along with increasing, for central processing unit 1 can be operated normally, so the computer dealer all can be provided with radiating module 2 on central processing unit 1.

The radiating module 2 of existing central processing unit 1, as shown in Figure 1, it mainly is installing one radiator 21 on central processing unit 1, and a radiator fan 22 is set above radiator 21, absorb by the thermal source of radiator 21 central processing unit 1, by radiator fan 22 thermal source is got rid of again, and be minimized the working temperature of central processing unit 1, in order to do making central processing unit 1 under suitable temperature environment, operate.

The installation of this radiating module 2, as shown in Figure 1, 2, the main runners 23 of establishing in the bottom side of circuit substrate 3, four corners of this runners 23 have extended respectively installs support arm 231, this support arm 231 is provided with the perforation 2311 that runs through, and this perforation 2311 can covering for bolt assembly 25.Also extended pin pipe 221 in four corners of radiator fan 22 in addition, this pin pipe 212 is corresponding with 2311 one-tenth of the perforation of support arm 231, and pin pipe 221 can supply wearing wherein of the solid assembly 27 of spiral shell in addition, and the outer peripheral face of the solid assembly 27 of this spiral shell is arranged with elastic parts 28.Radiating module 2 can penetrate from the pin pipe 221 of radiator fan 22 by the solid assembly 23 of spiral shell by this, and the perforation 31 of passing circuit substrate 3, and can be screwed with the bolt assembly 25 on the support arm 231 of runners 23, make the applying that radiating module 2 and central processing unit 1 can be firm.

The rigidity intensity of this circuit substrate 3 originally just a little less than, for exempting to cause the distortion of circuit substrate 3 because of the locking of radiating module 2, and then have influence on the running of central processing unit 1, so the module 2 of loosing directly spiral shell is solid on circuit substrate 3, and must be provided with runners 23 is installed with the back side at circuit substrate 3, therefore runners 23 must have suitable rigidity intensity, could allow radiating module 2 that certain stable position can be arranged.Be with, present dealer all makes runners 23 with metal material, obtains preferable rigidity intensity to pray.When runners 23 is that metal material is when made, the dealer avoids metal runners 23 to have influence on the circuit pathways of circuit substrate 3, so an insulating part 24 can be set between runners 23 and circuit substrate 3, the shape of this insulating part 24 is fully corresponding with 23 one-tenth of runners, the same support arm 241 that extended also is provided with perforation 2411 on this support arm 241 in its four corner.By the setting of insulating part 24, can avoid runners 23 to interfere with the circuit pathways of circuit substrate 3 really.

In addition, existing radiating module 2 is when assembling, earlier runners 23 and insulating part 24 are configured to one, again the bolt assembly on the runners 24 25 is passed in the perforation 31 of circuit substrate 3, for making runners 23 and exhausted source part 24 on circuit substrate 3, have stable paying temporarily to locate, must be in bolt assembly 25 upper ends a sheathed C type clasp 26, form by C type clasp 26 and to stop, or in the rubberizing mode, to avoid runners 23 and insulating part 24, in the assembling line flow process, on circuit substrate 3, come off, and assembling that can the convenient production line next stop.

Existing radiating module 2 no doubt can make central processing unit 1 reach the purpose of heat radiation, and the structure of module 2 but existing heat is loose still has following shortcoming at least:

1. because its runners 23 is made for metal material, and what still can impact the normal circuit path of circuit substrate 3, as producing electric field interference etc.

2. existing radiating module 2 must dispose insulating part 28 and gum operation between runners 23 and circuit substrate 3, and causes the increase of cost.

3. when existing radiating module 2 its runners 23 are done to pay temporarily on circuit substrate 3, must finish by a C type clasp 26, and the working procedure of installing engineering is increased.

Produce above-mentioned shortcoming for fear of existing metal runners 23; so there is the dealer to develop the runners made from the plastic material of high rigidity intensity; the runners that this plastic material is made is made with injection moulding; yet; owing to be easier to the phenomenon of rising-heat contracting-cold during injection moulding; often cause the surface of runners to produce jiggly state, when central processing unit turned round, vibrations or noise were given birth to because of the air spots stable yields of runners by regular meeting.

Be with, how to improve the shortcoming of existing runners, a real big problem that needs to be resolved hurrily for the dealer.

[summary of the invention]

Main purpose of the present utility model, be when the runners that improves existing central processing unit radiating module is made because of injection moulding easily, the phenomenon that rising-heat contracting-cold is arranged easily, cause the surface of runners to produce jiggly state, when central processing unit turns round, often give birth to vibrations or noise because of the air spots stable yields of runners.

For this reason, the utility model provides a kind of stand structure of central processing unit radiating module, be respectively equipped with top-holding part on the central authorities of this runners and the support arm in four corners, this top-holding part is upwards to be convexly equipped with the protrusion piece by the runners body to form, setting by this top-holding part, make runners have definite contact burnishing surface, locked when paying when runners by this in circuit substrate, can one stable and definite contacting be arranged with circuit substrate, and by setting up of this top-holding part, the bulk strength of runners can be effectively promoted, and then the use effect of the runners of central processing place device radiating module can be promoted.
