圖8顯示本發明散熱模組之組裝定位單元於彈性元件壓縮後之剖面示意圖。參考圖8,該組裝定位單元20處於一轉動位置,該組裝定位單元20之該驅動部21以向下之一驅動力驅動,例如以螺絲起子或自動化安裝設備驅動該驅動部21,使該第一限制部24脫離該設置孔111,且該彈性元件23被壓縮。該組裝定位單元20往下移動,使該第一限制部24之該第一延伸部241脫離該設置孔111,而位於該設置孔111下。此時,因該第一限制部24之該第一延伸部241未設置於該設置孔111內,故不會對該組裝定位單元20產生定位作用。因此,於該組裝定位單元20被該驅動力驅動往下後,該組裝定位單元20可依據該驅動力再進行轉動。8 shows a schematic cross-sectional view of the assembled positioning unit of the heat dissipation module of the present invention after the elastic element is compressed. Referring to FIG. 8 , the assembling and positioning unit 20 is in a rotating position, and the driving part 21 of the assembling and positioning unit 20 is driven by a downward driving force, for example, a screwdriver or an automatic installation device is used to drive the driving part 21 to make the first A restricting portion 24 is separated from the setting hole 111 , and the elastic element 23 is compressed. The assembling and positioning unit 20 moves downward, so that the first extending portion 241 of the first restricting portion 24 is separated from the setting hole 111 and located under the setting hole 111 . At this time, since the first extending portion 241 of the first restricting portion 24 is not disposed in the setting hole 111 , the positioning function of the assembly positioning unit 20 will not be generated. Therefore, after the assembling and positioning unit 20 is driven downward by the driving force, the assembling and positioning unit 20 can rotate again according to the driving force.

在一實施例中,於該轉動位置,因該組裝定位單元20往下移動且該彈性元件23被壓縮,該底座11之該第一凹槽115用以容置該桿體22之第一區段221。In one embodiment, in the rotating position, the first groove 115 of the base 11 is used to accommodate the first area of the rod body 22 due to the downward movement of the assembly positioning unit 20 and the compression of the elastic element 23 Paragraph 221.

圖9顯示本發明散熱模組之組裝定位單元於轉動後之剖面示意圖。參考圖9,該組裝定位單元20之該驅動部21再以一轉動力驅動,例如以螺絲起子或自動化安裝設備驅動該驅動部21轉動,使該第二限制部25轉動一角度,例如90度,使得該第二限制部25之該抵頂面252朝向該裝設板40之該第二表面42,且抵頂於該容置槽45。於該轉動力驅動時,該往下之驅動力仍存在,故該彈性元件23仍處於被壓縮狀態。於轉動力驅動後,移除螺絲起子或自動化安裝設備,未施加驅動力於該組裝定位單元20,可利用該彈性元件23之回復力,及該第二限制部25之該抵頂面252抵頂於該裝設板40之該第二表面42之該容置槽45,使得本發明之散熱模組1固定組裝至該電路板30及該裝設板40。FIG. 9 shows a schematic cross-sectional view of the assembled positioning unit of the heat dissipation module of the present invention after rotation. Referring to FIG. 9 , the driving part 21 of the assembling and positioning unit 20 is driven by a rotational force, for example, a screwdriver or an automatic installation device drives the driving part 21 to rotate, so that the second restricting part 25 is rotated by an angle, such as 90 degrees , so that the abutting surface 252 of the second restricting portion 25 faces the second surface 42 of the mounting plate 40 and abuts against the accommodating groove 45 . When the rotational force is driven, the downward driving force still exists, so the elastic element 23 is still in a compressed state. After the rotational force is driven, remove the screwdriver or the automatic installation equipment, without applying the driving force to the assembling and positioning unit 20, the restoring force of the elastic element 23 and the abutting surface 252 of the second restricting portion 25 can be used to abut The accommodating groove 45 on the second surface 42 of the installation board 40 makes the heat dissipation module 1 of the present invention fixedly assembled to the circuit board 30 and the installation board 40 .

因此,利用該組裝定位單元20之定位,使得本發明之散熱模組1可利用自動化組裝設備,對該組裝定位單元20進行自動化組裝,及便於後續組裝作業,以達到正確位置安裝、快速安裝、快速到位及節省安裝時間等功效。Therefore, by using the positioning of the assembly and positioning unit 20, the heat dissipation module 1 of the present invention can use automatic assembly equipment to automatically assemble the assembly and positioning unit 20, and facilitate subsequent assembly operations, so as to achieve correct position installation, rapid installation, Quickly in place and save installation time.
