Description

Heat abstractor

The utility model relates to a kind of heat abstractor, refers in particular to a kind of heat abstractor that is fitted on the computer CPU (central processing unit).

See also Figure 1A, it is the three-dimensional exploded view that has heat abstractor, CPU (central processing unit) now, reaches electric connector, electric connector 1 is substantially a flat board, on its plate face, be provided with several jacks 16, plate face periphery forms four sides, be respectively first side 11, second side 12, the 3rd side 13 and four side 14, wherein first side 11 is relative with the 3rd side 13, and second side 12 is relative with four side 14.A hinged operating rod 15 on first side 11 is in addition second, be respectively equipped with

lug

17,18 on the four side 12,14.CPU (central processing unit) (CPU) 2 also is substantially a flat board, is provided with several terminals 21 on its plate face.Heat abstractor 3 is by a fan 31, one radiating seats 32, and a pair of

clasp

33,34 formations, and wherein fan 31 is fixed on the radiating seat 32, and this is hinged on respectively on radiating seat 32

relative edges

33,34 of clasps.

Assemble above-mentioned heat abstractor 3, CPU (central processing unit) 2, and electric connector 1, can consult Figure 1A to 1C, electric connector 1 is welded on the motherboard (not shown) in advance in Figure 1A, the terminal 21 of CPU (central processing unit) 2 is aimed at the jack 16 of electric connector 1, it directly can be put into jack 12, pressing operating rod 15 according to the arrow E direction then makes CPU (central processing unit) 2 fixing, for another example shown in Figure 1B, earlier clasp 33 is hooked on the lug 17 of electric connector 1, then heat abstractor 3 is lain on the CPU (central processing unit) 2, this moment, clasp 34 still for rotatable state, pressed down clasp 34 at last according to the direction of arrow application of force, can make clasp 34 be hooked in intact assembling the on electric connector 1 another lug 18, shown in Fig. 1 C.

It is difficult that the dismounting of existing heat abstractor 3 is installed than it, see also Fig. 2, clasp 34 has elasticity for metallic article, in the end in installation steps clasp 34 to abut in lug 18 other, but be subject to lug 18 minimum points 181 and can't snap in lug 18 bottom surfaces, must force slightly elongation strain of clasp 34 this moment according to the arrow D direction application of force, after being lower than lug 18 minimum points 181, serve as axle rotation with pin joint 341 again and take advantage of a situation and slip into lug 18 bottom surfaces and finish assembling, but its situation is different fully during desire dismounting heat abstractor 3, forcing in clasp 34 according to arrow D direction equally forces it to reduce height, but clasp 34 can " not taken advantage of a situation " and be broken away from lug 18, cause because of pin joint 341 constraints is attached on the electric connector 1 clasp 34 more tightly on the contrary, therefore dismantling heat abstractor 3 needs on the hump, especially gather on the motherboard at CPU (central processing unit) 2 places various circuit board and electronic component its cause the space narrow and small, more be unfavorable for significantly dismounting action, the user feels worried and inconvenience for this reason.

The purpose of this utility model is to provide a kind of heat abstractor, and it has laborsaving lever, can overcome the shortcoming of prior art.

The purpose of this utility model is to realize like this, a kind of heat abstractor promptly is provided, be installed in and have four side, and wherein all be provided with on the plate electric connector of lug on two relative sides, and be arranged on the CPU (central processing unit) of above-mentioned electric connector, it comprises: a radiating seat, and it is that the material with high heat transfer coefficient is made the square body with high four side, its central authorities form a depressed part; One fan is fixed in the depressed part of above-mentioned radiating seat; Two clasps are hinged on respectively on above-mentioned radiating seat two relative sides, by the lug that hooks above-mentioned electric connector above-mentioned heat abstractor are fixed on the above-mentioned CPU (central processing unit); One laborsaving lever, it hingedly is arranged on one of above-mentioned clasp, above-mentioned laborsaving lever comprises first arm and second arm, above-mentioned first arm is by bearing above-mentioned heat abstractor of external force dismounting and above-mentioned electric connector, and above-mentioned second arm is resisted against above-mentioned electric connector as fulcrum when dismounting.

The advantage of heat abstractor of the present utility model is that its dismounting is all easy, simple and easy, the safety of operation, convenience on motherboard.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Figure 1A～1C is respectively existing heat abstractor, CPU (central processing unit), reaches each number of assembling steps stereographic map of electric connector;

Fig. 2 is that existing heat abstractor is installed in the synoptic diagram on the electric connector;

Fig. 3 A～3C is respectively the utility model heat abstractor, CPU (central processing unit), reaches each number of assembling steps stereographic map of electric connector;

Fig. 4 A～4C is respectively each demounting procedure synoptic diagram of the utility model heat abstractor.

See also Fig. 3 A, it is the utility model heat abstractor, CPU (central processing unit), reaches the three-dimensional exploded view of electric connector that wherein, the member identical with existing apparatus is marked with identical label and omits its explanation.Hingedly being provided with a laborsaving lever 35 on the clasp 34 of heat abstractor 3, serve as that the demarcate free end of should laborsaving lever 35 dividing into first arm 351 and second arm, 352, the first arms 351 is wound into the press section 3511 of tool cambered surface with pin joint 342 simultaneously.

Because laborsaving lever 35 is set, make heat abstractor of the present utility model, CPU (central processing unit), and electric connector is being torn open, load onto all and be very easy to, below illustrate with Fig. 3 A to Fig. 3 C, in Fig. 3 A electric connector 1 be welded on motherboard do not show) on, directly put into after the terminal 21 of CPU (central processing unit) 2 being aimed at the jack 16 of electric connectors 1, pressing operating rod 15 according to the arrow E direction then makes CPU (central processing unit) 2 fixing, then shown in Fig. 3 B, earlier clasp 33 is hooked on the lug 17 of electric connector 1, then heat abstractor 3 is lain on the CPU (central processing unit) 2, this moment, clasp 34 still was rotatable state, at last with the press section 3511 of handing laborsaving lever 35, according to arrow F direction slightly the application of force press down, can drive on another lug 18 that clasp 34 is hooked in electric connector 1 and finish assembling, shown in Fig. 3 C.

Mat uses laborsaving lever 35, and is easy too when the dismounting heat abstractor.Illustrate with Fig. 4 A to Fig. 4 C, force in the press section 3511 of laborsaving lever 35 according to the arrow G direction, can make laborsaving lever 35 serves as the axle rotation with pin joint 342, be resisted against electric connector 1 side (shown in Fig. 4 B) up to second arm 352, because the effect that external force G continues makes laborsaving lever 35 continue rotation, different is a laborsaving lever effect 35 this moment as a lever, its second arm 352 becomes fulcrum with the contact point 39 of electric connector 1, and being articulated in the pin joint 342 of clasp 34, laborsaving lever 35 becomes resistance points, the press section 3511 of laborsaving lever 35 becomes the point of application simultaneously, again since force arm length (promptly first arm 351 adds second arm, 352 length) always greater than drag arm lengths (i.e. second arm, 352 length), so this kind lever 35 is an a kind of labour-saving mechanism, only need apply a little strength, can force clasp 34 distortion that are positioned at resistance points and break away from lug 18, shown in Fig. 4 C.

Differ and be decided to be smooth cambered surface in the press section 3511 of laborsaving lever 35, the friction force in the time of can being provided with fold and being used for increasing touching.
