Under move a certain distance.
Two fixation kits 6 are respectively arranged at the opposite sides of the radiator 7, and each fixation kit 6 is under
It is supreme including one first locking part 61, a pad 62, a shell fragment 63, one second locking part 64 and two pins 65.
First locking part 61 is nut 61, and the bottom surface of metallic plate 1 is provided with a groove 11, and the nut 61 is movable
Ground is contained in groove 11, and the top surface of the metallic plate 1 is higher than the nut 61, and the metallic plate 1 can limit the nut 61
Move up.
As shown in Figure 2 and Figure 5, the shell fragment 63 is between the guide posts 31 and the fixed column 32, the shell fragment
There is an auxiliary section 631 among 63, the auxiliary section 631 is in horizontal plate shape, and the auxiliary section 631 is located at the fin portion 71
Underface, and the height of the auxiliary section 631 is between the top surface of the chip module 5 and bottom surface.From the cooperation
The opposite end of portion 631 is first bent obliquely respectively is folded upward at extension one elastic portion 632 of formation again, to strengthen the shell fragment 63
Elasticity, from the elastic portion 632 it is horizontal-extending formed a fixed part 633, the fixed part 633 be located at the recess 72 just under
Side, and parallel to the auxiliary section 631.
The pin 65 is passed down through the recess 72 and fixed part 633, and the shell fragment 63 is fixed on into the radiating
The bottom surface of device 7.
Second locking part 64 is screw 64, and the screw 64 includes a head 641, and the head 641 is welded in institute
State the top surface of auxiliary section 631（In other embodiments, the head 641 also the solderable bottom surface for being connected to the auxiliary section 631 or
It is riveting in the auxiliary section 631）, and the radiator 7 covers the top on the head 641, is downwardly extending from head 641
One bar portion 642, the bar portion 642 sequentially pass through downwards the framework 3, the circuit board 2 and the metallic plate 1, and with it is described
Nut 61 is coordinated by screw thread to lock.
The pad 62 is between the auxiliary section 631 and the framework 3.
As depicted in figs. 1 and 2, when assembling radiator 7, the head 641 of the screw 64 is first welded in the shell fragment
63 auxiliary section 631.As shown in figure 3, the fixed part 633 is fixed on to the bottom of the radiator 7 by the pin 65 again
Face.As shown in figure 4, then the radiator 7 is penetrated in the guide posts 31 and the fixed column 32, the now radiator

Locking is closed, now the bar portion 642 of the screw 64 sequentially passes through downwards the pad 62, the framework 3, the and of the circuit board 2
The metallic plate 1, rotate the nut 61 by operating（The radiator 7 can be spun upside down 180 ° to facilitate this operation）,
Lock so that the bar portion 642 and the nut 61 of the screw 64 are coordinated by screw thread, now the screw 64 is by downward
Active force, the auxiliary section 631 for compressing the shell fragment 63 downwards so as to the head 641 of the screw 64 move down so that described
Shell fragment 63 pulls down the radiator 7, is moved down so that the radiator 7 suppresses the chip module 5.As shown in fig. 6,
Until the bottom surface of the auxiliary section 631 is bonded with the top surface of the pad 62, and the bottom surface of the top surface of framework 3 and the pad 62
During fitting, the screw 64 and the nut 61 reach lockup state, just complete the assembling of the radiator 7.
Certainly, in other embodiments, first locking part 61 or screw 64, second locking part 64 is spiral shell
Mother 61；Or in other embodiments, it is also possible to a bottle opener（It is not shown）Second locking part is rotated through radiator 7
64, in this case, the metallic plate 1 may be alternatively located at the top of circuit board 2, and first locking part 61 is welded in the metallic plate
On 1.
In summary, radiator device combination of the present invention has following beneficial effect：
（1）The present invention only needs the cooperation of two set of first locking part 64 of locking part 61 and second and shell fragment 63, therefore need to only pacify twice
Dress process, be advantageous to save material cost and installation cost.Moved by the first locking part 61 and the second locking part 64 locking band
Piece 63, shell fragment 63 is set to pull down radiator 7, so that the chip module 5 of elasticity compacting downwards of radiator 7；Further, since shell fragment 63
The bottom surface of radiator 7 is fixed on, the space between radiator 7 and circuit board 2 is taken full advantage of to house shell fragment 63, will not take
The space of the top of radiator 7, saves space；Simultaneously as there are each shell fragment 63 two fixed parts 633 to be fixed on radiator
7 bottom surface, thus shell fragment 63 is more balanced to the press power of radiator 7.
（2）Due to being operation rotation first locking part 61 rather than operating the second locking part 64 of rotation, therefore radiator 7
Perforate is not needed to supply bottle opener in the top of second locking part 64（It is not shown）Pass through, and the present invention be different from it is traditional
The opening position operation of radiator 7 rotates second locking part 64, but radiator 7 is overturn into 180 ° to operate rotation described the
One locking part 61, to adapt to the demand of user.
（3）The pad 62 is between the auxiliary section 631 and the framework 3, top surface and institute when the pad 62
State the bottom surface fitting of auxiliary section 631, and when the bottom surface of the pad 62 is bonded with the top surface of the framework 3, the nut 61 and
Screw 64 reaches lockup state, thus can design the distance between the pad 62 and the auxiliary section 631 according to demand, keeps away
Exempting from the nut 61 excessively rotation causes the radiator 7 excessive to the press power of the chip module 5, and then prevents the core
Piece module 5 damages terminal by pressure, ensures reliable be electrically connected with.
（4）The fixture 73 and the fixed column 32 by thread locking to position the radiator 7, when described in upset
When radiator 7 is to rotate the nut 61, the radiator 7 and the chip module 5 can be avoided to drop and cause to damage, strengthened
The practicality of the radiator device combination 100.
Detailed description above is only the explanation of present pre-ferred embodiments, non-therefore the limitation present invention the scope of the claims, institute
So that all with this creation specification and diagramatic content institute, equivalence techniques changes for it, is both contained in the scope of the claims of this creation.
