Description

Fan fixer

The utility model is about a kind of fan fixer, particularly about a kind of fan fixer that can convenient and firmly install the different heights radiation fan.

Along with developing rapidly of computer industry, the arithmetic speed of central processing unit (CPU) is more and more faster, and the heat that is produced is also more and more, if these heats can't in time be discharged the stability when having a strong impact on the central processing unit (CPU) operation.Therefore, the sink combination that industry is made up of aluminium extruding radiator and fan in the installing one of central processing unit (CPU) end face usually is to assist heat radiation.The combination of this sink commonly used is normally offered tapped hole on the radiating fin of radiator, and by assistant tool (for example a word rise etc.) with screw respectively correspondence pass near fan four corners fixed hole, thereby radiator and fan are fixed together.But this mode of utilizing screw to fix fan commonly used, very easily causes the radiating fin torsional deformation even breaks under the trend of thin type development at the radiating fin of radiator, thereby can't firmly fix fan in the screw lock process; And this sink combination commonly used needs fan to be fixed on the radiator by assistant tool, because of very inconvenience of a little assemblings.In addition, Chang Yong this kind of screw lock means of fixation also can't satisfy the user replaces the different size fan fast when upgrading computer is safeguarded demand.

The purpose of this utility model is to provide a kind of fan fixer that can convenient and firmly install different heights specification radiation fan.

The purpose of this utility model realizes by following technical proposal: the utility model fan fixer, can be used to the fan of different heights specification is fixed on the radiator, it mainly comprises a square matrix, four projections, two pairs of first clamping parts and two pairs second clamping parts, square matrix is fixed on the radiator, it is one corresponding with fan and as the through hole of air communication channel that its central authorities offer, this projection by matrix four corners in the through hole outside respectively upwards projection form.Two opposite side of this matrix are extending upward two first clamping parts respectively corresponding to the suitable position of fan, this first clamping part top all correspondence is inwardly stretched and is established one first clasp, and below first clasp of this first clamping part, offer an elongated opening that runs through, this second clamping part is formed by the projection that makes progress of the diapire of this opening, and the free end of this second clamping part forms one second clasp corresponding to the first clasp lower direction inner bending.In addition, extend to form two buckling parts that are used for the corresponding fastener cooperation of radiator respectively downwards at these two ends, matrix bottom surface, and between two buckling parts of this matrix one end, stretch out a location projection downwards.

Advantage of the present utility model is: first clamping part of the utility model fan fixer has the first higher clasp, and second clamping part has the second lower clasp, therefore can fix the fan of two groups of different heights specifications respectively, to satisfy different heat radiation needs.In addition, the utility model fan fixer all is to adopt the structures such as projection, clasp 44, grab and the counter structure of fan or radiator to fasten the location, and it is more convenient, firm therefore to assemble.

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

Fig. 2 is the three-dimensional cutaway view of the utility model fan fixer.

Fig. 3 is the solid combination schematic representation of Fig. 1.

Fig. 4 is the three-dimensional combination figure of the fan of the utility model fan fixer and another height specification.

Please refer to Fig. 1, the utility model fan fixer 30 is used for a fan 10 is fixed on the radiator 20.Wherein this radiator 20 mainly comprises a base 22 and a plurality of from these base 22 upwardly extending radiating fins 24, these radiating fins 24 central authorities form grooves 28, and bend inwards respectively on radiating fin 24 tops of these radiator 20 opposite ends and to extend one and be used for and barb 26 that fan fixer 30 fasteners cooperate.This fan 10 is positioned at fan fixer 30 tops, its box-like body that roughly is square, and have certain altitude, run through respectively near its four corner and offer one and be used for and fan fixer 30 location cooperates the button hole 12 of usefulness, in addition in being respectively equipped with two grooves 14 on the sidewall around this fan 10.

Please also refer to Fig. 2, this fan fixer 30 mainly comprises a square matrix 31, these matrix 31 central authorities offer one with fan as the through hole 32 of air communication channel, and in matrix 31 4 corners in these through hole 32 outsides taper projection 34 that upwards projection one is used for and button hole 12 location of fan 10 cooperate respectively.Offer an elongated slot 36 on the matrix 31 of each projection 34 side, the corresponding inwall of these elongated slots 36 is one elastic projection 38 of projection laterally respectively, and these elastic projection 38 free ends are located the size error that cooperate with compensation fan 10 with fan fixer 30 a little more than matrix 31 end faces.The relative both side edges of this matrix 31 then extends upward respectively corresponding to fan 10 sidewall notches 14 positions and forms two first clamping parts 42, each clamping part 42 top is all corresponding inwardly stretches and establishes one and be used for and first clasp 44 that the end face lateral margin fastener of fan 10 cooperates, and this first clamping part 42 is offered an elongated opening that runs through 46 below this first clasp 44, the diapire of this opening 46 projection one second clamping part 48 that makes progress, corresponding first clasp 44 of the free end of this second clamping part 48 bends inwards and extends to form one second clasp 52.Two buckling parts 54 have been extended to form respectively downwards at these two ends, matrix 31 bottom surface, each buckling part 54 end all to evagination establish one be used for and radiator 20 opposite end radiating fins 24 on the grab 56 that cooperates of the corresponding fasteners of

barb

26,54 of two buckling parts at these matrix 31 1 ends stretch out a location projection 58 downwards, are positioned at corresponding inserted in the groove 28 of radiator 20.

Please also refer to Fig. 3, during assembling, earlier this fan 10 is placed fan fixer 30 tops also to push downwards, the button hole 12 that makes these fan 10 4 corners fit respectively is positioned on the corresponding projection 34 of fan fixer 30, thereby and make first clasp, 44 fasteners of this fan fixer 30 reach the purpose of fixing at the corresponding lateral margin of fan 10 end faces place; Then, the combination of this fan 10 and fan fixer 30 together is positioned over radiator 20 tops, the locating bump 58 corresponding plug-in cards of these fan fixer 30 1 ends are positioned in the groove 28 of radiator 20, push downwards then make these fan fixer 30 bottom surfaces grab 56 fasteners on the corresponding barb 26 of radiator 20, can finish assembling.

Please continue with reference to figure 4, the utility model fan fixer 30 also can pass through the fan 10 ' of another different heights specification of second clasp, 52 snaps into position of second clamping part 48.
