Description

The heat abstractor combination

[technical field]

The utility model is about the combination of a kind of heat abstractor, refer in particular to a kind of can be pre-aligned, in conjunction with equalization of pressure, and heat abstractor easy to assembly combination.

[background technology]

Central processing unit is the nerve center of computer treatmenting information, and can the overall performance of computing machine promote, and depends on the performance of central processing unit to a great extent, so the release of high-frequency high-speed central processing unit just becomes inevitable trend.But, the heat that high-frequency high-speed will cause central processing unit to produce is more and more, further make the computer-internal temperature more and more higher, serious prestige is being assisted the stability of central processing unit operation, for guaranteeing central processing unit energy operate as normal, the heat that it produced must in time be discharged, for this reason, the be everlasting surface of central processing unit of industry installs heat abstractor combination additional, with the heat of timely its generation of discharge.

Fixing structure of radiator has two kinds usually: a kind of is that heating radiator is placed in the storage tank with the fixedly module of its corresponding cooperation, relend help fastener with heating radiator and fixedly the module one be fastened on the connector that is equiped with central processing unit, but, in this fixed form, the overall weight of heating radiator all concentrates on the central processing unit, not only is difficult to pass through vibration-testing, and, very easily cause the adhesion inequality, cause the surface local loose contact, thereby influence radiating effect; Another kind of radiating mode is to establish screw on foot of radiator, and on the connector of mainboard or installing central processing unit, be provided with screw corresponding with it, relend help screw directly with heating radiator locking on mainboard or connector, but, there is the problem of location difficulty in this fixed form when assembling, and because this fixed form is rigidly connected, cause the pressure inequality easily, cause a plurality of binding site imbalance of pressure on the heating radiator after the assembling, both influenced radiating effect, and made circuit board produce mechanically deform again easily.

[summary of the invention]

The purpose of this utility model be to provide a kind of can be pre-aligned, easy to assembly, and can guarantee to combine between heating radiator and the heater element heat abstractor combination of equalization of pressure.

The purpose of this utility model realizes by following technical proposal: the combination of the utility model heat abstractor comprises a heating radiator, a backboard and several fixtures, this heating radiator comprises a pedestal and the radiating fin that extends vertically upward of this pedestal certainly, four jiaos of appropriate positions of this pedestal are established a fixed orifice respectively, one disposal area is formed at this fixed orifice top, one positioning area is formed at the bottom, and the middle part then is a threaded area; This backboard comprises a main part, and four corners are provided with a projection respectively corresponding to the fixed orifice place of radiator base on it, and the top of each projection is provided with a screw; This fixture is made up of screw, pad and spring, can be installed in the fixed orifice of heating radiator in advance, the projection of this backboard can pass on the circuit board corresponding through hole and be contained in the positioning area of this pedestal fixed orifice, screw locking by these fixtures makes heating radiator be close to the wafer surface of circuit board in the screw of these projections.

The advantage of the utility model heat abstractor combination is: can be pre-aligned, assembling easily, and combine equalization of pressure between fixing back heater element and the heat abstractor, both avoided to guarantee better heat radiating effect again owing to the uneven circuit board mechanically deform that causes of adhesion.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]

Please consult Fig. 1 and Fig. 2 simultaneously, the combination of the utility model heat abstractor comprises a heating radiator 10, a backboard 30 and several fixtures 40, be used for fixing on circuit board 50 and assist wafer 60 heat radiation, this circuit board 50 respectively is provided with a through hole 52 at wafer 60 4 corners.

This heating radiator 10 comprises a pedestal 12 and the upwardly extending radiating fin 14 of these pedestal 12 end faces certainly, the through hole 52 of this 12 4 jiaos of appropriate positions of pedestal corresponding circuits plate 50 is respectively equipped with a fixed orifice 16, one disposal area 18 is formed at the top of this fixed orifice 16, one positioning area 22 is formed at the bottom, and its middle part then is a threaded area 24.

This backboard 30 comprises that one is criss-cross main part 32, these main part 32 central authorities run through and offer a through hole 34, and its four jiaos places all upwards protrude out a projection 36, can corresponding pass the through hole 52 of circuit board 50 and be contained in the fixed orifice 16 of this heating radiator 10, these projection 36 tops are provided with a screw 38, and the reach of this screw 38 is a certain value.In addition, this backboard 30 around through hole 34 and projection 36 bottoms all be equiped with cushion pad 39, be used for preventing damage circuit board 50 when this backboard 30 combines with this circuit board 50.

This fixture 40 is made up of screw 42, pad 44 and spring 46 etc., this spring 46 can partly be housed in the disposal area 18 of these heating radiator 10 fixed orifices 16 in advance, and this screw 42 can pass this pad 44 and spring 46 back screw locks successively in the threaded area 24 of the fixed orifice 16 of this heating radiator 10, thereby these fixtures 40 tentatively are fixed on this heating radiator 10.

Please consult Fig. 3 simultaneously, during assembling, earlier projection 36 correspondences of backboard 30 are passed the through hole 52 of circuit board 50, assembly with this heating radiator 10 and fixture 40 is placed on the wafer 60 of this circuit board 50 again, and the projection 36 that makes this backboard 30 is contained in the positioning area 22 of these heating radiator 10 fixed orifices 16, at last, by means of screw 42 screw locks of fixture 40 in the screw 38 of these backboard 30 projections 36, thereby this heat abstractor combination is fixed on this circuit board 50, and makes this heating radiator 10 be close to the surface of wafer 60.At this moment, 46 on this spring is housed in the disposal area 18 of this fixed orifice 16 fully, and, because the reach of these projection 36 screws 38 is a certain value, so after this screw 42 screws in fully the pressure of 10 4 jiaos in this heating radiator is kept in balance.
