Referring to fig. 4 to 6, the heat dissipation assembly 100 includes a heat sink 10 and a fan 20. The heat generated by the operation of the first circuit board 300 and the second circuit board 400 can be conducted to the heat dissipation assembly 100, and the fan 20 operates to establish an air flow, which rapidly takes the heat on the heat sink 10 out of the receiving cavity 201.

In the embodiment of the present invention, the heat sink 10 includes a first heat-conducting portion 11, a second heat-conducting portion 14, at least one heat-dissipating fin 12, and a connecting plate 15. The heat sink 10 may be made of a material having a good heat conductivity, such as an aluminum alloy, and the first heat conduction portion 11, the heat dissipation fins 12, the second heat conduction portion 14, and the connection plate 15 may be integrally formed, or may be assembled after being separately manufactured.

The first heat conduction portion 11 may be used to conduct heat on the first circuit board 300. Specifically, in the embodiment of the present invention, the first heat conduction portion 11 is a flat plate, the first heat conduction portion 11 includes a first surface 111 and a second surface 112 opposite to each other, and the first surface 111 may be substantially parallel to the second surface 112. The first surface 111 is used for being attached to the first circuit board 300 to increase the heat conduction area between the first circuit board 300 and the first heat conduction portion 11, and to quickly transfer heat generated by the operation of the first circuit board 300 to the first heat conduction portion 11. It is understood that the number of the first circuit boards 300 attached to the first surface 111 may be one, or may be multiple, and a plurality of the first circuit boards 300 may be arranged side by side so that each of the first circuit boards 300 is attached to the first surface 111.

The second heat conduction portion 14 is connected to the first heat conduction portion 11, and the second heat conduction portion 14 can be used for conducting heat on the second circuit board 400. Specifically, in the embodiment of the present invention, the second heat conduction portion 14 is flat as a whole, and the second heat conduction portion 14 and the first heat conduction portion 11 extend in substantially the same direction. The second heat conduction portion 14 has a third surface 141 formed thereon, the third surface 141 and the first surface 111, and the third surface 141 and the second surface 112 may be parallel or non-parallel. The third surface 141 is used for being attached to the second circuit board 400 to increase the heat conducting area between the second circuit board 400 and the second heat conducting portion 14, and to quickly transfer heat generated by the operation of the second circuit board 400 to the second heat conducting portion 14. It is understood that the number of the second circuit boards 400 attached to the third surface 141 may be one or more, and a plurality of the second circuit boards 400 may be arranged side by side so that each of the third circuit boards is attached to the third surface 141. It is understood that, since the second heat conduction portion 14 is connected to the first heat conduction portion 11, the heat of the second heat conduction portion 14 is transferred to the first heat conduction portion 11 by heat transfer.

The number of the heat dissipation fins 12 is at least one, the heat dissipation fins 12 are formed on the second surface 112, and the heat dissipation fins 12 may be in a sheet shape, so that the heat dissipation fins 12 have a larger contact area with air, which is beneficial to rapid heat exchange between the heat dissipation fins 12 and the air. At least one of the heat radiating fins 12 forms a heat radiating air duct 121. Specifically, when the number of the heat dissipation fins 12 is one, the heat dissipation fins 12 may be used to limit at least one side of the heat dissipation air duct 121, or the heat dissipation fins 12 surround the heat dissipation air duct 121; when the number of the heat dissipation fins 12 is plural, the plural heat dissipation fins 12 are arranged at intervals, and a heat dissipation air duct 121 can be formed between every two adjacent heat dissipation fins 12. In the embodiment of the present invention, the number of the heat dissipation fins 12 is taken as an example for description, and the extending directions of the heat dissipation fins 12 may be the same, so that the extending directions of the heat dissipation air channels 121 are all the same.

The heat generated by the first circuit board 300 is further transferred to the heat dissipation fins 12 after being transferred to the first heat conduction portion 11, and the heat generated by the second circuit board 400 is further transferred to the first heat conduction portion 11 and further transferred to the heat dissipation fins 12 after being transferred to the second heat conduction portion 14. Therefore, the heat generated by the first circuit board 300 and the second circuit board 400 is finally transferred to the heat dissipation fins 12 and dissipated to the air in the heat dissipation air duct 121 through the heat dissipation fins 12. The outlet of the heat dissipation air duct 121 can be aligned to and close to the air outlet 203, so that air flow passing through the heat dissipation air duct 121 is established, air flow in the heat dissipation air duct 121 can be driven, and finally the air flows out of the accommodating cavity 201 from the air outlet 203, and in the process, the blown air can take away heat gathered in the heat dissipation air duct 121, so that the purpose of heat dissipation of the remote controller 1000 is achieved.

The connecting plate 15 connects the first heat-conducting portion 11 and the second heat-conducting portion 14. Specifically, the connection plate 15 connects one end of the first heat conduction portion 11 and one end of the second heat conduction portion 14, and more specifically, the connection plate 15 connects an end surface of the first heat conduction portion 11 near the second heat conduction portion 14, and an end portion of the second heat conduction portion 14 near the first heat conduction portion 11. Further, the extending direction of the connecting plate 15 may be different from the extending direction of the first heat conduction part 11 and the second heat conduction part 14, for example, the connecting plate 15 forms a right angle or an acute angle with the first heat conduction part 11 and the second heat conduction part 14, so that there is a height difference between the first heat conduction part 11 and the second heat conduction part 14. In the embodiment of the present invention, the first heat conduction portion 11, the connection plate 15, and the second heat conduction portion 14 have the overall zigzag shape in the side surface, and the heat of the second heat conduction portion 14 can be transmitted to the first heat conduction portion 11 through the connection plate 15.

Referring to fig. 5 to 7, further, the first surface 111 and the connection board 15 form a first accommodating space 16, and the first accommodating space 16 can be used for accommodating the first circuit board 300, that is, the first circuit board 300 is accommodated in the first accommodating space 16 while the first circuit board 300 is attached to the first surface 111. The third surface 141 and the connecting plate 15 form a second accommodating space 17, and the second accommodating space 17 can be used for accommodating the second circuit board 400, that is, the second circuit board 400 is accommodated in the second accommodating space 17 while the second circuit board 400 is attached to the third surface 141. In the embodiment of the present invention, the first accommodating space 16 and the second accommodating space 17 are located at two sides of the connecting plate 15, and the heights of the first accommodating space 16 and the second accommodating space 17 are substantially the same, so that when the first circuit board 300 is accommodated in the first accommodating space 16, the first circuit board 300 is substantially flush with the second heat conducting portion 14, and when the second circuit board 400 is accommodated in the second accommodating space 17, the second circuit board 400 is substantially flush with the first heat conducting portion 11, so that when the first circuit board 300 and the second circuit board 400 are matched with the heat sink 10, the overall structure is more compact.

Of course, in other embodiments, the connecting plate 15 may be omitted, and the first heat conduction portion 11 and the second heat conduction portion 14 may be directly connected; alternatively, the specific shape of the connecting plate 15 may be other forms, for example, the extending direction of the connecting plate 15 may be the same as the first heat-conducting portion 11 and the second heat-conducting portion 14, and the like, which is not limited herein.

Referring to fig. 3 and 4, the fan 20 is mounted on the heat sink 10, and the fan 20 is used for establishing an air flow passing through the heat dissipation air duct 121 to dissipate heat transferred from the second heat conduction portion 14 and the first heat conduction portion 11 to the heat dissipation fins 12. The blower 20 includes a bracket 22 and a fan 21.

The bracket 22 is mounted on the heat sink 10, and specifically, the bracket 22 may be detachably mounted on the first heat conduction portion 11, and more specifically, the bracket 22 may be detachably mounted on an end of the first heat conduction portion 11 close to the second heat conduction portion 14. In an embodiment of the present invention, please refer to fig. 11 and 12, the bracket 22 includes a connecting lug 225, and a fixing hole 2251 is formed on the connecting lug 225. The heat sink 10 includes fixing posts 18, the fixing posts 18 being formed on the first heat conduction portion 11, and fixing holes 181 being formed in the fixing posts 18. The fixing post 18 and the connecting lug 225 are connected by a fastening member 600, such as a screw, passing through the fixing hole 2251 of the connecting lug 225 and the fixing hole 181 of the fixing post 18, thereby mounting the bracket 22 on the first heat conduction part 11. The holder 22 is detachably connected to the first heat conduction portion 11, so that it is convenient to replace a different holder 22, or to remove the holder 22 for further maintenance or replacement of other functional modules of the remote controller 1000. Of course, in other embodiments, the bracket 22 may also be mounted on the second heat conduction portion 14 or the second circuit board 400, or the like; the detachable connection between the bracket 22 and the first heat-conducting portion 11 may be in other specific forms, for example, a connection by engaging the bracket 22 with the first heat-conducting portion 11, which is not limited herein.

Referring to fig. 7 to 10, the fan 21 is mounted on the bracket 22, and the fan 21 is used for establishing an air flow through the heat dissipation air duct 121. In the embodiment of the present invention, after the fan 21 is installed on the bracket 22, the position of the fan 21 corresponds to the position of the second heat conduction portion 14, an accommodating space is formed between the second heat conduction portion 14 and the fan 21, the accommodating space may be the second accommodating space 17, and the second circuit board 400 may be accommodated in the accommodating space. The fan 21 has an air inlet 211 and an air outlet 212. The air inlet 211 may be communicated with the accommodating space, and the air inlet 211 may be opened toward the second circuit board 400, so that the air enters the air inlet 211 and simultaneously takes away a part of heat emitted from the second circuit board 400. It is understood that the position of the air inlet 211 is only exemplary and not limited herein.

When the fan 21 is mounted on the heat sink 10 through the bracket 22, a mounting plane of the fan 21 is substantially flush with a plane (i.e., the second surface 112) where the heat dissipation air duct 121 is located, an air outlet direction of the fan 21 is consistent with an extending direction of the heat dissipation air duct 121, or, at the air outlet 212, a flow direction of an air flow established by the fan 21 is consistent with the extending direction of the heat dissipation air duct 121, so as to reduce loss of the air flow in the heat dissipation air duct 121 and enable the air flow to pass through the heat dissipation air duct 121 at a higher speed, thereby improving the heat dissipation efficiency of the heat dissipation assembly 100. Further, in the embodiment of the present invention, the air outlet 212 of the fan 21 is connected to the heat dissipation air duct 121, so that the airflow flowing out from the air outlet 212 directly enters the heat dissipation air duct 121, and the amount of air leaking out of the heat dissipation air duct 121 is reduced, so as to further improve the heat dissipation efficiency of the heat dissipation assembly 100.

In the embodiment shown in fig. 1 to 4, when the heat dissipating assembly 100 is installed in the receiving cavity 201 of the housing 200, the first heat conducting portion 11 is close to the top of the remote controller 1000, and the second heat conducting portion 14 is close to the bottom of the remote controller 1000. The first side 111 is closer to the front side 2041 of the main body 204 than the second side 112, and the second side 112 is closer to the back side 2042 of the main body 204 than the first side 111. When the first circuit board 300 and the second circuit board 400 are attached to the heat sink 10, the first circuit board 300 is located between the first heat conducting portion 11 and the front surface 2041, and the second circuit board 400 and the fan 20 are both located between the second heat conducting portion 14 and the back surface 2042. The cover 205 is aligned with the fan 21, the cover 205 is aligned with the second circuit board 400.

In summary, in the remote controller 1000 according to the embodiment of the present invention, one heat sink 10 can be attached to the first circuit board 300 and the second circuit board 400 of the remote controller 1000 at the same time, and the air flow generated by the fan 20 is utilized to dissipate the heat generated on the first circuit board 300 and the second circuit board 400 through the heat dissipation air duct 121, so that the remote controller 1000 has a better heat dissipation performance through one heat dissipation assembly 100, and the heat dissipation assembly 100 is conveniently disposed in the remote controller 1000, thereby saving the space in the remote controller 1000.
