Description

The buckling device of computer cpu heat radiator

The utility model relates to a kind of buckling device of computer cpu heat radiator, is meant a kind of buckling device that dispels the heat on the central processing unit ZIF runners that heat radiator is fixed on especially.

Along with the continuous lifting of computer cpu computing execution speed, the temperature of corresponding generation also improves constantly, and the too high stability that central processing unit is carried out of temperature can produce totally unfavorable influence.For this reason, the heat dissipation problem of central processing unit is more and more paid attention to by industry, and the invention and the utility model of heat abstractor and fastener thereof also emerge in an endless stream.Heat radiator fastener early can be consulted accompanying drawing 1, No. the 84207163rd, the patent of Taiwan shown in 2, it discloses a kind of being used in conjunction with heat radiator, the buckling device of central processing unit and ZIF runners, this buckle plywood 1 have that a level is horizontally set with by branch 2, extend to form a shell fragment 3 at this by the branch 2 both sides angle that is inclined upwardly respectively, and extend to form both sides side plate 4 downwards by these shell fragment 3 free ends, respectively establish low opening 5 and a higher opening 6 on this both sides side plate 4, wherein the top margin of low opening 5 extends a sheet metal downwards, its inboard also is provided with a projection that is used for being snapped on ZIF runners 11 trips, base by this higher opening 6 protrudes upward a sheet metal 7 in addition, and this sheet metal 7 keeps certain distance with the upper limb of this opening 6, as the point of application of instruments such as finger or bottle opener; When assembling, earlier central processing unit 8 is inserted on the ZIF runners 11, again heat radiator 9 is placed the top of central processing unit 8, the set trip in the no fin zone 10 that makes heat radiator 9 and ZIF runners 11 both sides in line, to point again or instrument such as bottle opener is placed on the sheet metal 7 at buckle plywood 1 biside plate 4 higher openings 6 places, outwards downwards the application of force so that buckle plywood 1 heat radiator, central processing unit and ZIF runners are closely snapped together.But because above-mentioned computer cpu heat radiator buckling device volume is less, and in assembling process, the activity space of this buckling device is restricted, if so when assembling remove to pull the set sheet metal of this buckling device side plate of pressure with finger, then operation is comparatively difficult, and the damage finger greatly reduces packaging efficiency easily; In addition, press the set sheet metal of this buckling device side plate, then skidding occurs because of operating physical force size and direction control are bad easily again, make motherboard impaired if in assembling process, adopt mounting or dismounting tools such as bottle opener to pull.For this reason, need provide a kind of new structure to solve these problems.

The purpose of this utility model is to provide a kind of and heat radiator and central processing unit can be fitted tightly together, and button keeps steady admittedly the buckling device of the central processing unit heat radiator of simple operation, safety.

Another purpose of the present utility model provides a kind of energy simplifies, optimizes structure, and reduces the buckling device of the computer cpu heat radiator of die cost.

Therefore, the technical solution of the utility model is: this heat radiator buckling device is by a long-bar metal plate punching press bending forming, mainly comprise the butting section that a level is horizontally set with, stretch out by these two ends, butting section and to form a shell fragment portion, this shell fragment portion end is bent to form one first buckling parts and one second buckling parts again downwards, be respectively equipped with a button hole that is used for fastening central processing unit ZIF runners two ends trip near each buckling parts bottom, and terminal outwards little the sticking up of these buckling parts is convenient to buckle and carried out smoothly.In addition, this second buckling parts fin that extends outwardly out further is provided with a sled hole on this fin, can be used as the point of application of mounting or dismounting tools such as bottle opener, and can prevent that it from skidding.

Compared with prior art, the utlity model has following remarkable advantage: this heat radiator buckling device not only loads and unloads simple and convenient but also easy location, can not skid because of application of force size and direction bad appearance, thereby avoid the impaired situation of motherboard to take place.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 2 is the three-dimensional combination figure of existing heat radiator buckling device and heat radiator, central processing unit and ZIF runners.

Fig. 3 is the three-dimensional exploded view of the utility model heat radiator buckling device and heat radiator, central processing unit and ZIF runners.

Synoptic diagram when Fig. 4 is the dismounting of the utility model heat radiator buckling device.

See also Fig. 3, present embodiment heat radiator buckling device 20 mainly comprises a butting section 22 by a long-bar metal plate punching press bending forming, and level crosses on the heat radiator 30, can be used to compress heat radiator 30 itself and central processing unit 40 surfaces are fitted tightly together; Being inclined upwardly respectively by these 22 two ends, butting section extends to form a shell fragment portion 24, required elastic force in the time of can providing this butting section to compress heat radiator; Bent down respectively by these shell fragment portion 24 ends in addition and extend to form one first buckling parts 26 and one second buckling parts 28, these buckling parts 26,28 bottom end vicinities respectively are provided with a button hole 32; And the fin 34 that upwards extends outwardly out in button hole 32 tops of second buckling parts 28, further be provided with a square sled hole 36 on this fin, can be used as the point of application of mounting or dismounting tools such as bottle opener, and can prevent it from skidding and cause the situation of motherboard damage to take place.When assembling, earlier central processing unit 40 is plugged on the ZIF runners 50, again heat radiator 30 is placed on the top of this central processing unit 40, the no fin groove 38 that makes heat radiator 30 and the set trip in ZIF runners 50 both sides are in line, then heat radiator buckling device 20 is placed in this no fin groove 38, and utilize mounting or dismounting tools such as bottle opener to be installed in these heat radiator buckling device 20 set sled holes 36, application of force clinching should be prized set fin 34 on the hole 36, cause set trip 52 buckles on these heat radiator buckling device 20 set button holes 32 and the ZIF runners, promptly finish assembling.

See also Fig. 4, in the heat abstractor unloading process, earlier bottle opener is plugged and be resisted against in these heat radiator buckling device 20 set sled holes 36, then pull the fin 34 of this heat radiator buckling device 20 along A direction sled by this bottle opener, and make set button hole 32 below it break away from the trip 52 of ZIF runners 50, just can remove this heat abstractor.
