DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0028] like Figures 1 to 4 As shown, an embodiment of the utility model provides a heat sink 100, comprising: a shell 110, and a heat dissipation module 120 and a connecting assembly 130 connected to the shell 110, the heat dissipation module 120 comprises a connecting frame 122 connected to the shell 110, a heat conductive sheet 124 and a heat dissipation frame 126 connected to the connecting frame 122, and a heat dissipation fan 128 arranged in the heat dissipation frame 126, wherein the heat dissipation frame 126 is connected to the heat conductive sheet 124, and the connecting assembly 130 can move relative to the heat dissipation module 120 so that the heat conductive sheet 124 protrudes from the connecting assembly 130, or the heat conductive sheet 124 is flush with the end of the connecting assembly 130.

[0029] Specifically, the embodiment of the present application is explained by taking the heat dissipation of an electronic device as an example. The heat dissipation surface on the electronic device may have a sunken plane or a flat plane and other structural forms. For the above forms, the radiator 100 provided in the embodiment of the present application can adjust the relative position between the heat dissipation module 120 and the connecting component 130 when in use. When in use, the heat dissipation module 120 can be moved relative to the shell 110, and the connecting component 130 can be fixed relative to the shell 110 to adjust the relative position of the two. The heat dissipation module 120 can also be fixed relative to the shell 110, and the connecting component 130 can be moved relative to the shell 110 to adjust the relative position of the two.

[0030] In addition, the heat dissipation module 120 plays a stable supporting role through the connecting frame 122 connected to the housing 110, which is conducive to ensuring the stability of the heat conductive sheet 124 and the heat sink 126 set on the connecting frame 122. Among them, the heat conductive sheet 124 is used to connect with the heat dissipation surface of the electronic device to transfer the heat generated by the electronic device to the heat sink 126 through the heat conductive sheet 124, and through the cooperation of the heat dissipation fan 128 and the heat sink 126, the heat dissipation ability of the heat sink 126 is improved, thereby reducing the temperature of the electronic device. In actual applications, the heat conductive sheet 124 can be protruded from the connecting component 130 to adapt to the recessed plane. The heat conductive sheet 124 can also be flush with the end of the connecting component 130 to adapt to the flat plane. The connecting component 130 ensures a stable connection between the radiator 100 and the electronic device.

[0031] The heat sink 100 provided in the embodiment of the present application is in contact with the electronic device through the housing 110, and the heat dissipation module 120 and the connection assembly 130 connected to the housing 110. When in use, the heat dissipation module 120 contacts the electronic device, and is connected to the electronic device through the connection assembly 130 to ensure the stability of the heat dissipation process. The heat dissipation module 120 is connected to the housing 110 through the connecting frame 122, and the connecting frame 122 is also connected with a heat conductive sheet 124 and a heat dissipation frame 126. A heat dissipation fan 128 is arranged in the heat dissipation frame 126. The heat conductive sheet 124 can directly contact the electronic device and transfer heat to the heat dissipation frame 126. When the heat dissipation fan 128 in the heat dissipation frame 126 is running, the heat dissipation frame 126 is quickly cooled to accelerate heat transfer and improve the heat dissipation effect. In addition, when connected to an electronic device through the connecting component 130, the heat dissipation module 120 can move relative to the connecting component 130 so that the heat conductive sheet 124 protrudes from the connecting component 130, or the heat conductive sheet 124 is flush with the end of the connecting component 130, so as to adapt to different forms of electronic devices. By adopting the above form, the compatibility of the radiator 100 can be improved, thereby improving the applicability of the radiator 100 when in use.

[0032] like Figure 2 and Figure 3 As shown, the connecting frame 122 includes a first connecting part 1222, a second connecting part 1224 and a third connecting part 1226 which are connected in sequence, the first connecting part 1222 is connected to the shell 110, the heat conductive plate 124 is located at the third connecting part 1226, the connecting component 130 is located at the outer ring of the second connecting part 1224, and the connecting component 130 can move along the axial direction of the second connecting part 1224.

[0033] Specifically, the connecting frame 122 is an annular structure as a whole, and the first connecting part 1222 is connected to the shell 110 and can be fastened by screws when connected. The second connecting part 1224 cooperates with the connecting component 130 to enable the connecting component 130 to move axially relative to the second connecting part 1224, so that the heat conducting plate 124 located at the third connecting part 1226 protrudes from the connecting component 130, or the heat conducting plate 124 is flush with the end of the connecting component 130.

[0034] like Figure 2 and Figure 3 As shown, the connection assembly 130 includes an adjustment frame 132 , and a magnetic attraction member 134 , an adhesive member or a clamping member disposed on the adjustment frame 132 . The connection assembly 130 is threadedly connected to the second connection portion 1224 through the adjustment frame 132 .

[0035] Specifically, when the adjustment frame 132 is provided with a magnetic member 134, it can be connected to the electronic device by magnetic attraction; when the adjustment frame 132 is provided with an adhesive member, it can be connected to the electronic device by bonding; when the adjustment frame 132 is provided with a clamping member, it can be connected to the electronic device by clamping. The position of the connection component 130 itself can be adjusted by threading the adjustment frame 132 with the second connection part 1224, so as to flexibly adjust the relative position between the connection component 130 and the heat dissipation module 120.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, when a magnetic attraction member 134 is provided on the adjustment frame 132, the adjustment frame 132 includes an annular frame body 1322, an annular groove 1324 is provided on the annular frame body 1322, and the magnetic attraction member 134 is located in the annular groove 1324; the outer ring of the second connecting portion 1224 is provided with a thread, the inner ring of the annular frame body 1322 is provided with a clamping protrusion 1326 clamped with the thread, and an annular rib 1328 is also provided on the annular frame body 1322, and an avoidance groove corresponding to the annular rib 1328 is provided on the shell 110.

[0037] Specifically, the magnetic suction member 134 is set in an annular shape so as to be placed in the annular groove 1324. When applied to an electronic device that can be directly magnetically adsorbed, the relative position between the heat dissipation module 120 and the connecting assembly 130 is adjusted first, and then the magnetic suction member 134 is directly used for adsorption. When the second connecting portion 1224 is connected to the adjustment frame 132, by setting a thread on the outer ring of the second connecting portion 1224, and the inner ring of the annular frame 1322 is provided with a clamping protrusion 1326 that is clamped with the thread, the thread engagement relationship can be achieved between the clamping protrusion 1326 and the second connecting portion 1224. In addition, an annular rib 1328 is also provided on the annular frame 1322. When the annular frame 1322 moves in a direction away from the housing 110, the annular rib 1328 can be used to shield the area between the housing 110 and the annular frame 1322 to prevent foreign matter from entering the housing 110. When the annular frame 1322 moves toward the direction where the housing 110 is located, the annular frame 1322 can smoothly move toward the position where the housing 110 is located through the avoidance grooves provided on the housing 110 and corresponding to the annular retaining edges 1328 .

[0038] like Figure 3 As shown, in an optional embodiment of the present application, a cover plate 136 is further provided on the annular frame 1322 , and the cover plate 136 is covered on the annular groove 1324 to shield the magnetic attraction member 134 .

[0039] By adopting the above method, the magnetic member 134 can be shielded and protected by the cover plate 136 to prevent the magnetic member 134 from being directly exposed to the outside, which is conducive to improving the reliability of the connection between them. Among them, a sinking groove can be set on the annular frame 1322, and the cover plate 136 is set in the sinking groove to prevent the cover plate 136 from protruding from the annular frame 1322. In addition, the cover plate 136 and the annular frame 1322 can be connected by bonding.

[0040] In another optional embodiment of the present application, Figures 6 to 8 As shown, the connecting assembly 130 includes an adjusting frame 132, and the adjusting frame 132 includes an annular frame body 1322. A magnetic attraction member 134, an adhesive member or a clamping member is provided on the annular frame body 1322. An annular rib 1328 is also provided on the annular rib 1328. A buckle 1329 is provided on the annular rib 1328. A first card slot 112 and a second card slot 114 corresponding to the buckle 1329 are provided on the shell 110. A connecting column 116 for connecting the first connecting part 1222 is also provided in the shell 110. The buckle 1329 can be clamped in the first card slot 112. An elastic member 140 is provided on the connecting column 116. One end of the elastic member 140 is elastically abutted against the annular rib 1328, so that when the buckle 1329 is released from the first card slot 112, the buckle 1329 can slide in the second card slot 114.

[0041] Specifically, when a magnetic attraction member 134 is provided on the annular frame 1322, it can be connected to the electronic device by magnetic attraction; when an adhesive member is provided on the annular frame 1322, it can be connected to the electronic device by bonding; when a clamping member is provided on the annular frame 1322, it can be connected to the electronic device by clamping. When the annular frame 1322 moves away from the shell 110, the annular rib 1328 provided on the annular frame 1322 can shield the area between the shell 110 and the annular frame 1322 through the annular rib 1328 to prevent foreign matter from entering the shell 110. For example, it can prevent fingers from being inserted into the shell 110 during use, and when the annular frame 1322 moves toward the direction of the shell 110, the fingers are accidentally squeezed and injured. In addition, through the cooperation between the buckle 1329 and the first slot 112 or the second slot 114, when the buckle 1329 is clamped with the first slot 112, it can limit the connection component 130, and at this time, the heat conductive sheet 124 protrudes from the connection component 130. When it is necessary to release the limit of the buckle 1329 by the first slot 112, the buckle 1329 can be manually pressed, and the buckle 1329 is deformed by force to release the limit with the first slot 112. At this time, the annular retaining edge 1328 is moved away from the housing 110 by the elastic force of the elastic member 140, and after the buckle 1329 is no longer subjected to the pressing force, it restores its own deformation and is clamped in the second slot 114, thereby achieving a sliding connection with the second slot 114. In this way, after the connection component 130 is connected to the electronic device, the positional relationship between the connection component 130 and the heat conductive sheet 124 can be changed, so as to better adapt to the electronic device.

[0042] like Figure 4 combine Figure 8 As shown, the radiator 100 also includes a wireless charging module 150, which includes an iron core 152 arranged in the third connecting portion 1226, and a coil 154 stacked and wound around the outer circle of the iron core 152, the iron core 152 and the coil 154 are respectively attached to the thermal conductive sheet 124, so that the heat sink 126 is connected to the thermal conductive sheet 124 through the wireless charging module 150, and the coil 154 is electrically connected to the circuit board of the radiator 100.

[0043] Specifically, the wireless charging module 150 can charge the electronic device with wireless charging function on the one hand, and can also play a role of heat conduction, so that the heat generated by the electronic device is transferred to the heat sink 126 through the heat conducting sheet 124 and the iron core 152 in sequence. In addition, the circuit board is also provided with a switch and a plug port to power on the radiator 100 and control the start and stop of the cooling fan 128 through the switch.

[0044] like Figure 4 and Figure 8As shown, the heat sink 126 includes a thermally conductive base 1262 and a plurality of heat sinks 1264 disposed on the thermally conductive base 1262 , and the thermally conductive base 1262 and the heat sinks 1264 form an accommodating space for accommodating the cooling fan 128 ; the radiator 100 also includes a thermally conductive block 160 , and the thermally conductive base 1262 is connected to the iron core 152 via the thermally conductive block 160 .

[0045] In actual applications, due to the distance between the heat conducting sheet 124 and the heat conducting base 1262, in order to ensure normal heat conduction, it is sometimes necessary to use the heat conducting block 160 to achieve heat transfer, and apply thermal grease on the contact surface to improve the heat conduction efficiency. When the heat is transferred to the heat conducting base 1262, it can be dispersed to the heat sink 1264 to improve the heat dissipation capacity. At the same time, the air flow at the heat sink 1264 is strengthened by the heat dissipation fan 128 to improve the heat dissipation efficiency.

[0046] like Figure 7 As shown, the outer ring of the shell 110 is provided with a plurality of strip holes 118 , which correspond to the heat sink 1264 ; the end surface of the shell 110 is also provided with a plurality of through holes, which correspond to the heat dissipation fan 128 .

[0047] Specifically, by providing the strip-shaped holes 118 on the outer ring of the housing 110, the heat sink 1264 is exposed, thereby enhancing the air flow with the outside world and improving the heat dissipation efficiency. In addition, by providing the through holes on the end surface of the housing 110, the convection between the outside world and the heat dissipation fan 128 is facilitated, and the heat dissipation fan 128 is protected to prevent foreign matter from affecting the normal operation of the heat dissipation fan 128. The through holes may be circular holes, fan-shaped holes, or diamond-shaped holes, etc., and are not specifically limited by the embodiments of the present application.

[0048] In an optional embodiment of the present application, a magnetic member 170 or an adhesive is further provided on the end surface of the shell 110, and the magnetic member 170 or the adhesive is located on the outer circle of the end surface.

[0049] By adopting the above method, when the electronic device is relatively small, such as a mobile phone, it can be connected to the back cover of the mobile phone through the connecting component 130 so that the heat dissipation module 120 can dissipate heat for the mobile phone. At the same time, the mobile phone can be fixed on the bracket through the radiator 100. When fixed, it can be connected through the magnetic part 170 or the adhesive on the end face, thereby improving the applicability during use.

[0050] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
