Technical solutions of the utility model are further elaborated with reference to the accompanying drawings and examples, present embodiment can have
Different form and it is not understood as limited to explanation set forth herein.Identical reference numeral represents identical always in text
Element, similar reference numeral represent similar element.
As shown in Figure 1 to Figure 3, a kind of heat spreader structures are mainly used for radiating to the heating device 7 in system, especially
It is including heat sink body 2, fan 3 and fan 3 to be fixed on heat dissipation for radiating to the heating device in sound system
Fixing piece 6 in main body 2, heat sink body 2 includes cooling fin 21 and pedestal 22 and the two is integrally formed, heat sink body 2 and fan 3
On be equipped with and passed through for fixing piece 6 and the mutual corresponding hole 5 in position, in order to make heat sink body 2 and fan 3 be sealedly connected on one
It rises, additionally includes a sealing element 4, heat sink body 2 is removably sealedly connected on fan 3 by sealing element 4 and fixing piece 6
Together, the radiator body 2 after connection and fan 3 are fixed on the pcb board 1 in system and form one between pcb board 1 relatively
Closed air flow channel 8, wherein cooling fin 21 is set in the air flow channel 8, and the heating device 7 on pcb board 1 is fixed on pedestal
22 both sides.
In order to which heat sink body 2 and fan 3 to be removably attachable to together, on four angles of heat sink body 2 and fan 3
Respectively open up the hole 5 that at least one position corresponds and quantity is equal, preferred through-hole in this programme, the pedestal 22 of heat sink body 2
One end be bottom surface, the other end is top surface, in order to hide fixing piece 6 and locking piece and reach aesthetic effect, in the top surface and
Two corners between cooling fin 21 adjacent thereto respectively open up a cylindrical hole.Fan 3, sealing element 4 and heat dissipation are led when connection
5 position of through-hole on body 2 corresponds, and is penetrated in cylindrical hole after fixing piece 6 is then passed through through-hole 5, then with locking
Part is locked, and the preferred fixing piece 6 of this scheme is bolt, and locking piece is nut.Heat sink body 2 and fan 3 after combination is solid
It is connected on the pcb board 1 in system, wherein pedestal 22 is contacted with pcb board 1, is then made between pcb board 1, heat sink body 2, fan 3
Form a closed air flow channel 8 relatively, wherein in order to improve the radiating rate of cooling fin 21, cooling fin 21 is set to the air stream
In road 8, in order to all concentrate on wind-force in air flow channel 8,3 air outlet diameter of fan and the diameter of section of air flow channel 8 are big
Cause it is identical,
Heat sink body 2 can also be overall structure in this programme, but overall structure can cause to mold of high cost, another mold
All be ironware itself just than heavier, too big mold not only take up space and meanwhile also be inconvenient to carry, separately product damage when
It is also required to integral replacing, substantially increases replacement cost, substandard products are inevitably had in actual production operation and defective products generates, it is whole
