Description

Device in order to combination CPU and heat radiator

The utility model relates to a kind of device in order to combination CPU and heat radiator.

As everyone knows, the central processing unit of computer (Central Process Unit, hereinafter to be referred as CPU) when starting computing, can produce high temperature, if can not be with its timely eliminating, then can influence its performance, even burn, especially the arithmetic speed fast heat that CPU produced of healing is higher, and its influence is more remarkable; Therefore, any host computer all must be provided with heat abstractor to get rid of the heat that CPU was produced.

Generally for the arithmetic speed heat abstractor design of CPU faster, mainly be that the heat radiator with plurality of fins directly is set on CPU, and on this heat radiator, fan is set, the most heat that is produced during this CPU computing is absorbed by this heat radiator, and this CPU starts fan running simultaneously when computing and blow heat radiator and reach thermolysis.The mode on CPU of traditionally heat radiator being made up has multiple, and what wherein be widely used is that periphery at heat radiator is provided with a plurality of barbs, is provided with flange in the neighboring of CPU in addition, uses the barb of heat radiator to be fastened the flange of CPU and fix.Yet, must heat radiator be pressed on CPU with big strength in the solid mode of barb mating flanges button, therefore, if careless manipulation is so that the application of force is easy to injure precision and fragile CPU when excessive; So, generally when assembling, all must very careful and lentamente heat radiator be made up on CPU, thereby reduce packaging efficiency; And its fastening structure is comparatively complicated, and manufacturing cost is higher.Though other that minority arranged in addition is with CPU and the fixing design of heat radiator combination, its structure is also rather complicated, and the cost of development of mould is higher, causes manufacturing cost high.So the utility model is improved at the disappearance that above-mentioned traditional C PU and heat radiator are had on assembling.

Fundamental purpose of the present utility model is utilized the structure of simplifying in that a kind of device in order to combination CPU and heat radiator is provided, and central processing unit and the heat radiator that is used in computer can be made up quickly and easily or dismantle.

Based on this, the utility model is the device in order to combination CPU and heat radiator that provides at the CPU that is respectively equipped with corresponding hole and heat radiator, and this device is to include one first fastener and one second fastener; This first fastener is to form arc bending shape, and has extended a plurality of extending pins, and the end of this extending pin is provided with clasp; This second fastener is provided with the curved edge of a plurality of extending pin positions corresponding to this first fastener, and this curved edge is provided with and is continuously by the prominent rail of low gradually high arc, and is provided with a recess and a stop section in the highest point of the prominent rail of this arc; Be to utilize the extending pin of this first fastener to pass heat radiator and the set hole of CPU, make the curved edge of this second fastener be matched with this clasp and relative rotation with the prominent rail of arc, this clasp is moved along the curved edge and the prominent rail of arc of second fastener, buckle into this recess and locate up to this clasp, and then this first fastener and second fastener are fixed together heat radiator and CPU clamping.

The utility model can also following manner further be realized:

This first fastener is to form H shape, and described extending pin extends four jiaos of ends in this H shape respectively.

This first fastener forms the rectangle frame form, and described extending pin extends four jiaos of ends in this rectangle frame respectively.

The highest point of the prominent rail of the arc of this second fastener is provided with the stop section adjacent to this recess.

This second fastener is provided with two at least and is positioned at the tab that relative position is used for this second fastener of rotation.

Clearly, utilize the utility model can make the assembling of CPU and heat radiator or dismounting more quick, convenient, and then the enhancement work efficiency.

As shown in Figure 1, device in order to combination CPU and heat radiator provided by the utility model, mainly be to be provided with the design of

hole

13,21 respectively at ad-hoc location at heat radiator 1 and CPU 2, and the device that provides a kind of energy that this heat radiator 1 and CPU 2 combinations are fixed together.

Device of the present utility model is to include one first fastener 3 and one second fastener 4; Wherein, a wherein embodiment of this first fastener 3, be with sheet material with suitable elasticity and toughness (for example steel spring plate, sheet metal ... Deng) form the H shape, and make two cross bars 31 of this H shape form arc bending shape, then the vertical pole 32 of perpendicular connection between this two cross bar 31, the end of this cross bar 31 has vertically extended an extending pin 33 respectively, and the end of this extending pin 33 is formed with clasp 331.The preferred embodiment of this second fastener 4 is also with sheet material with suitable elasticity and toughness (steel spring plate for example, sheet metal, Deng) integrated punching is shaped to the curved edge 41 of extending pin 33 positions with corresponding above-mentioned first fastener 3, this curved edge 41 is to form non-circular camber line, but be the camber line (as shown in Figure 5) that flaring is opened with respect to just round line A, and this curved edge 41 vertically is provided with and is continuously by the prominent rail 42 of low gradually high arc, and be provided with a recess 44 in the highest point of the prominent rail 42 of this arc, then be provided with a higher and outstanding stop section 43 adjacent to the highest point of this recess 44; Again, this second fastener 4 also stamps out two tabs 45 that only are connected in second fastener, 4 bodies on one side in the impact briquetting mode, and this two tab 45 is to be positioned at relative position, this two tab 45 is respectively vertical bending and outstanding second fastener, 4 bodies, can utilize two fingers to hold this two tab 45 and with its rotation according to this.

By above-mentioned first fastener 3 of the present utility model and second fastener 4, it is in order to do combination fixedly the time to heat radiator 1 and CPU 2, at first this heat radiator 1 must be processed earlier according to the shape of 3 moulding of first fastener, so that this first fastener 3 can fit in bottom surface, heat radiator 1 top fully; In the present embodiment, be that radiating fin 11 at this heat radiator 1 cuts out the groove 12 of two roads corresponding to cross bar 31 positions of this first fastener 3, this cross bar 31 can be inserted in this groove 12 and adhere on the bottom surface, top of heat radiator 1 fully, this vertical pole 32 is then inserted by the slit of 11 of adjacent two radiating fins, even also the arc of this first fastener 3 is bent the bottom surface, top that raised face fits in this heat radiator 1; Behind the hole 13 that its extending pin 33 with first fastener 3 passes heat radiator 1 simultaneously and the hole 21 of CPU 2, again second fastener 4 is adhered on the opposite face of CPU 2, make this extending pin 33 be contacted with this curved edge 4, make this clasp 331 be contacted with the prominent rail 42 of this arc simultaneously, then promptly can hold this two tab 45 and rotate second fastener 4 by two fingers, this clasp 331 is moved with the prominent rail 42 of arc along the curved edge 41 of second fastener 4, buckle into this recess 44 and locate up to this clasp 331, and utilize this stop section 43 to prevent that clasp 331 from continuing to move and surpass the highest point (as shown in Figure 4) of the prominent rail 42 of arc; Utilize this clasp 331 in the process that the prominent rail 42 of arc moves, extending pin 33 axially to be spurred, and then first fastener 3 that originally is arc bending shape is driven plain gradually and has the strength of elasticity compressing heat radiator 1, thereby this first fastener 3 and second fastener 4 are fixed together heat radiator 1 and CPU 2 clampings (as shown in Figures 2 and 3); And utilize this curved edge 41 to be gradually the camber line of expansion, and extending pin 33 is expanded outwardly in the process that moves along its edge, thereby have elastic force and clamp second fastener 4, make the combination between the two more firm.
