Abstract

The utility model discloses a button device structure of the CPU radiator. A mainboard is provided with a fixed seat which has a CPU thereon, and the CPU is provided with a radiator which is fixed on the CPU through the button device, and the upper of the radiator is provided with a fan. The heat from the CPU is absorbed by the radiator, and then is excluded by the fan; the button device is a long flakey elastic plate whose two ends slightly bend upwards, and each of the two ends of the elastic plate is provided with a bolt. The mainboard is provided with an opposite perforation, and therefore the button device is made to span on the radiator, and the bolts on the two ends of the button device is made to thrill through the perforation of the mainboard; the radiator, CPU and the fixed seat are closely combined with the mainboard through the bolts on the two ends of the button device of long flakey elastic plate inserted and installed on the mainboard.

Description

The buckle structure of cpu heat

Technical field

The utility model is a kind of buckle structure of cpu heat, refer in particular to a kind of fastener that radiator is fixed on the CPU top, its two ends are the lengthy motion picture shape shell fragment that upwarps, and the two ends at shell fragment respectively are provided with latch, latch is inserted on the motherboard, radiator, CPU and holder are combined closely on motherboard.

Background technology

The CPU of general computer can produce high heat when running, therefore suitably heat radiation is avoided CPU Yin Gaore and damaged, and CPU can operated under normal temperature environment.

Shown in Figure 6 is that tradition is installed in the radiator structure on the CPU, is to go up installing earlier in order to the holder c of fixation of C PUb in motherboard a, installs CPUb, radiator d and fan e in regular turn in holder c top; The both sides of holder c are provided with colludes piece c1, two ends are had the shell fragment f that colludes hole f1 downwards to bridge above fin d, and make the both sides that hole f1 is buckled in holder c of colluding at shell fragment f two ends be provided with and collude on the piece c1, radiator d is installed in the CPUb top, so radiator d can be absorbed CPUb generation heat when running removes hot type by fan e, reduce the working temperature of CPUb, this CPUb can be turned round under normal temperature.Its major defect is:

Since radiator d by shell fragment f spiral-lock above holder c, make this radiator d be pressed against the CPUb top, and CPUb installs holder c top, holder c is installed in motherboard a top again, so holder c, CPUb and radiator d repeatedly are fitted together, and above radiator d, must install fan e; Because motherboard a normally vertically is installed in the interior (not shown) of the frame of computer, making holder c, the CPUb, radiator d and the fan e that repeatedly are fitted together is that state with spiral arm is arranged on the motherboard a, and between holder c and motherboard a the pin (not shown) fixed support by holder c bottom surface only, so more built on the sand, and the fault that causes holder to get loose easily has the drawback of loose contact in the use.

Summary of the invention

At above-mentioned defective, the inventor develops research, creates the technical solution of the utility model.

Main purpose of the present utility model provides a kind of buckle structure of cpu heat, be on the holder of installing on the motherboard, to install CPU, and above CPU, be equiped with radiator, radiator is to be fixed in the CPU top by fastener, and above radiator, be equiped with fan, absorb the heat that CPU produced by radiator, by fan hot type is removed again; Detaining it is the lengthy motion picture shape shell fragment that two ends slightly upwarp, and respectively is equiped with a latch at the two ends of shell fragment, and motherboard is provided with relative perforation, makes the fastener must be on radiator, and the perforation that makes the latch at its two ends pass motherboard; The latch at the fastener two ends by lengthy motion picture shape shell fragment is inserted into motherboard, reaches combine closely purpose on motherboard of radiator, CPU and holder.

The purpose of this utility model is achieved in that a kind of buckle structure of cpu heat, be on motherboard, to be equiped with holder, on this holder, install CPU3, above CPU3, install radiator, radiator is to be fixed in the CPU3 top by fastener, above radiator, be equiped with fan, it is characterized in that:

This fastener is the lengthy motion picture shape shell fragment that two ends slightly upwarp, latch is respectively installed at two ends at shell fragment, is provided with relative perforation on motherboard, and this fastener is on radiator, make the latch at its two ends pass perforation on the motherboard, radiator, CPU and holder are combined closely on motherboard.

The two ends of this fastener have perforation, these perforation both sides are communicated with rectangular opening, this perforated side has two positioning convex points, the ailhead below of this latch has two lugs, this latch is penetrated by the perforation of this fastener, and two lugs of this latch are passed by the rectangular opening of perforated side, rotate latch again, one of them lug gets on the positioning convex point that leans against fastener earlier on this latch side, and this latch assembling is fixed on the fastener.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

Embodiment

Consult Fig. 1-shown in Figure 5, the utility model is to be equiped with holder 2 on motherboard 1, on this holder 2, install CPU3, installing radiator 4 above CPU3, radiator 4 is to be fixed in the CPU3 top by fastener 5, is equiped with fan 6 above radiator 4, absorbs the heat that CPU3 produced by radiator 4, by fan 6 hot type is removed again, it is characterized in that:

The lengthy motion picture shape shell fragment that this fastener 5 slightly upwarps for two ends, latch 51 is respectively installed at two ends at shell fragment, on motherboard 1, be provided with relative perforation 11, make this fastener 5 on radiator 4, make the latch 51 at its two ends pass perforation 11 on the motherboard, as shown in Figure 3, radiator 4, CPU3 and holder 2 are combined closely on motherboard 1.

According to above-mentioned structure, because fastener 5 is across above radiator 4, and the latch that makes these fastener 5 two ends interted in the perforation 11 of motherboard 1 in 51 minutes, these fastener 5 two ends are fixed on the motherboard 1, so, radiator 4, CPU3 and holder 2 threes closely are fitted on the motherboard 1, so can increase the intensity that supports by fastener 5, have preferable combination assembling intensity, the defective of avoiding traditional structure to cause holder to get loose easily has preferable result of use.

Owing to only the latch 51 at fastener 5 two ends of lengthy motion picture shape shell fragment directly must be inserted in the perforation 11 of motherboard 1, can finish assembling, be convenient to the user and install voluntarily.

Consult Fig. 4 and shown in Figure 5, fastener 5 two ends have perforation 52, be communicated with rectangular opening 55 in these 52 both sides of boring a hole, and have two positioning convex points 53 at perforation 52 sides, the ailhead below of this latch 51 has two lugs 54, this latch 51 is penetrated by the perforation 52 of this fastener 5, and two lugs 54 that make this latch 51 are passed by the rectangular opening 55 of perforation 52 sides, rotate latch 51 again, make on latch 51 sides one of them lug 54 earlier on the positioning convex point 53 of fastener 5, latch 51 assemblings are fixed on the fastener 5.

Comprehensive the above, the disclosed structure of the utility model is not have toward sheet, can reach preferable effect really.
