Moreover, robots typically have 3-5 heat sources, which are dispersed. In related technologies, heat sink components for dissipating heat sources suffer from problems such as unreasonable airflow design and large space occupation, resulting in significant airflow loss within the airflow channels and low heat dissipation efficiency for the heat sources.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following is combined Figures 1-5 A heat sink assembly according to an embodiment of the present invention is described.

[0032] The radiator assembly of this embodiment includes a heat sink housing 1, a first heat sink component 2, and a cooling fan 3. The heat sink housing 1 has a heat dissipation channel extending along a first direction. A first air inlet and a first air outlet are respectively provided on opposite side walls of the heat sink housing 1 along the first direction. The heat sink housing 1 includes a heat exchange portion 11 for exchanging heat with a main heat source 53. At least a portion of the first heat sink component 2 is disposed within the heat dissipation channel and exchanges heat with the heat exchange portion 11. The cooling fan 3 is connected to the heat sink housing 1, and the cooling fan 3 and the heat sink housing 1 are arranged along the first direction.

[0033] According to the embodiment of the present invention, the heat sink assembly forms a heat dissipation channel extending along a first direction by setting a heat dissipation shell 1. The heat dissipation shell 1 has a first air inlet and a first air outlet on its two opposite side walls along the first direction. When the cooling fan 3 is working, the outside air enters the heat dissipation channel through the first air inlet and is finally discharged through the first air outlet. It is basically not blocked by the heat dissipation shell 1 and thus does not cause airflow loss. This ensures that more airflow exchanges heat with the first heat sink 2, so that the first heat sink 2 can dissipate heat quickly so that the heat from the main heat source 53 can be quickly removed through the heat exchange section 11. The heat dissipation efficiency of the main heat source 53 is high.

[0034] It should be noted that the heat dissipation housing 1 includes a lower shell and an upper cover. The upper cover is detachably connected to the lower shell via a threaded connection, and the two form a heat dissipation channel. At least a portion of the first heat dissipation component 2 is fitted into the heat dissipation channel through the upper opening of the lower shell. The bottom plate of the lower shell has a notch, and the heat exchange section 11 includes a copper plate disposed at the notch to seal it. The copper plate achieves heat exchange between the main heat source 53 and the first heat dissipation component 2 through contact. The copper plate has higher thermal conductivity than other materials. Both the lower shell and the upper cover are made of plastic to effectively reduce the weight and cost of the heat dissipation housing 1.

[0035] In some embodiments, the first heat sink 2 includes a plurality of first heat sink fins 21, the first heat sink fins 21 are located in the heat dissipation channel and are in contact with the heat exchange part 11, and the thickness direction of the first heat sink fins 21 is orthogonal to the first direction.

[0036] The arrangement of multiple first heat dissipation fins 21 creates a larger heat dissipation area within the heat dissipation channel, facilitating heat exchange between the air entering the channel and the first heat dissipation fins 21 for rapid heat dissipation of the main heat source 53, resulting in higher heat exchange efficiency for the main heat source 53. Furthermore, the thickness direction of the first heat dissipation fins 21 is orthogonal to the first direction, ensuring that a gap connecting the first air inlet and the first air outlet is formed between any two adjacent first heat dissipation fins 21. This facilitates sufficient heat exchange between the air entering the heat dissipation channel and the first heat dissipation fins 21, while also allowing air to be smoothly exhausted to the outside through the first air outlet.

[0037] For example, such as Figure 1 and Figure 2 As shown, the first direction is consistent with the length direction of the heat dissipation channel, and multiple first heat dissipation fins 21 are arranged at intervals along the width direction of the heat dissipation channel. Each first heat dissipation fin 21 is in heat exchange contact with the heat exchange part 11. The length of each first heat dissipation fin 21 is approximately equal to the length of the heat dissipation channel, and the height of the first heat dissipation fin 21 is approximately equal to the height of the heat dissipation channel.

[0038] In some embodiments, the first heat sink 2 includes a first heat pipe 22, which contains a phase change material. The first heat pipe 22 includes a first pipe segment 221, a second pipe segment 222, and a third pipe segment 223 connected in sequence. At least a portion of the first pipe segment 221 is located in the heat dissipation channel and exchanges heat with the heat exchange section 11. At least a portion of the third pipe segment 223 is located in the heat dissipation channel. On a projection plane perpendicular to the first direction, the projection of the third pipe segment 223 is located on the side where the projection of the first pipe segment 221 is opposite to the projection of the heat exchange section 11.

[0039] When the first section 221 of the first heat pipe 22 exchanges heat with the heat exchange section 11, the phase change material rapidly absorbs heat through a state change and can quickly transfer the absorbed heat to the third section 223. Its heat transfer efficiency is higher than that of the first heat dissipation fins 21. At this time, the first heat pipe 22 can dissipate heat to a region in the heat dissipation channel further away from the heat exchange section 11 through the third section 223, thereby further facilitating sufficient heat exchange with the air entering the heat dissipation channel and further improving the heat dissipation efficiency of the main heat source 53.

[0040] For example, such as Figure 1 and Figure 5 As shown, the third pipe section 223 is in heat exchange contact with all the first heat dissipation fins 21, thereby enabling the third pipe section 223 to quickly transfer the heat near the heat exchange section 11 to the area of ​​the first heat dissipation fins 21 away from the heat exchange section 11, and thus achieve more efficient heat exchange with the air in the heat dissipation channel.

[0041] It should be noted that the lower and upper ends of the first heat dissipation fin 21 are respectively provided with insertion holes for the first pipe section 221 and the third pipe section 223 to be inserted. In addition, the phase change material can be a solid-liquid phase change material, such as sodium sulfate decahydrate or calcium chloride, or a solid-solid phase change material, such as polyethylene glycol.

[0042] In some embodiments, the second pipe segment 222 is located on the outside of the heat dissipation housing 1. The wall of the heat dissipation housing 1 is provided with a first insertion hole and a second insertion hole that communicate with the heat dissipation channel. The first pipe segment 221 passes through the first insertion hole, and the third pipe segment 223 is inserted into the second insertion hole.

[0043] At this time, the heat from the main heat source 53 can also be dissipated to the outside of the heat dissipation shell 1 through the second pipe section 222. At the same time, it can also effectively avoid setting the second pipe section 222 in the heat dissipation channel and affecting the arrangement area of ​​the first heat dissipation fins 21 in the heat dissipation channel, thereby further improving the heat dissipation efficiency of the main heat source 53.

[0044] For example, such as Figure 1 and Figure 2 As shown, the first heat pipe 22 is a flexible tube, the first pipe section 221 and the third pipe section 223 are both straight pipe sections, and the second pipe section 222 includes at least one arc-shaped pipe section to facilitate the connection of the two.

[0045] In some embodiments, there are multiple first heat pipes 22 arranged at intervals along a first direction.

[0046] The arrangement of multiple first heat pipes 22 spaced apart along the first direction allows heat from the heat exchange section 11 to be directed to a position further away from the heat exchange section 11 along the first direction via multiple third pipe sections 223. This results in heat being more evenly distributed to more locations in the heat dissipation channel in the vertical direction and in the first direction, thereby further improving the heat dissipation efficiency of the main heat source 53.

[0047] For example, such as Figures 1-4 As shown, there are four first heat pipes 22, and the four third pipe sections 223 are all adjacent to the top cover and at the same height. The two third pipe sections 223 located at the edge are adjacent to the first air inlet and the first air outlet, respectively.

[0048] In some embodiments, the radiator assembly further includes a second heat sink 4, a portion of which is heat-exchange connected to the first heat sink 2, and another portion of which is located on the outside of the heat sink housing 1 and is used for heat exchange with the secondary heat source 54.

[0049] The second heat sink 4 transfers the heat from the secondary heat source 54 to the heat dissipation channel, so as to facilitate heat exchange with the air entering the heat dissipation channel, thereby achieving rapid heat dissipation of the secondary heat source 54. This ensures that the heat sink assembly of this embodiment can dissipate heat from more heat sources and effectively guarantee the working performance of the robot.

[0050] For example, the number of secondary heat sources 54 can be one, two or more. For instance, the secondary heat source 54 can be a battery module installed on the circuit board 52, and the main heat source 53 can be a central control module installed on the circuit board 52.

[0051] In some embodiments, the second heat sink 4 includes a heat exchange plate 41 and a second heat pipe 42. The heat exchange plate 41 is used to exchange heat with the secondary heat source 54. The second heat pipe 42 is provided with a phase change material. The first end of the second heat pipe 42 is connected to the heat exchange plate 41, and the second end of the second heat pipe 42 is located in the heat dissipation channel.

[0052] By changing the state of the phase change material, the heat transferred from the secondary heat source 54 to the heat exchange plate 41 can be quickly transferred to the heat dissipation channel. Compared with other heat dissipation components, it has a higher heat transfer efficiency, thus making the secondary heat source 54 have a higher heat dissipation efficiency.

[0053] For example, the lower shell of the heat exchange housing has insertion holes on its side wall for the second heat pipe 42 to pass through, and each first heat dissipation fin 21 has insertion holes for the second heat pipe 42 to be inserted, thereby ensuring heat exchange contact between the second heat pipe 42 and each first heat dissipation fin 21. The heat exchange plate 41 is used to make close contact with the secondary heat source 54 to increase the heat exchange area between them, thereby improving the heat exchange efficiency. There are two second heat pipes 42 arranged at intervals along a first direction.

[0054] In some embodiments, the second heat sink 4 further includes a second heat sink fin 43, which exchanges heat with the heat exchange plate 41.

[0055] The arrangement of the second heat dissipation fin 43 effectively increases the heat exchange area of ​​the second heat dissipation component 4, thereby further improving the heat dissipation efficiency of the secondary heat source 54.

[0056] For example, such as Figure 1 As shown, the second heat source is in heat exchange contact with the second heat dissipation fin 43.

[0057] The robot torso device according to an embodiment of the present invention includes a functional module 5 and a heat sink assembly as described in any of the above embodiments. The functional module 5 includes a main heat source 53, and the heat exchange part 11 exchanges heat with the main heat source 53.

[0058] The technical advantages of the robot torso device according to the present invention are the same as those of the heat sink assembly in the above embodiments, and will not be repeated here.

[0059] In some embodiments, the functional module 5 further includes a support frame 51 and a circuit board 52, the circuit board 52 being mounted on the support frame 51, and the main heat source 53 being disposed on the side of the circuit board 52 facing away from the support frame 51. The heat sink assembly also includes a support leg 12 connected to the heat sink housing 1, the support leg 12 being connected to the support frame 51 by fasteners.

[0060] At this time, when the heat sink assembly is impacted, the impact force will be directly transmitted to the support frame 51, instead of directly impacting the circuit board 52 and damaging the circuit board 52 and its electronic components, thus extending the service life of the robot torso device.

[0061] For example, such as Figures 1-4 As shown, there are four legs 12, which are respectively located at the four corners of the bottom plate of the heat sink housing 1. The legs 12 are provided with mounting holes, and the support frame 51 is provided with threaded holes. The fasteners are bolts, which pass through the mounting holes and are threadedly connected to the threaded holes.

[0062] In some embodiments, one of the support frame 51 and the leg 12 is provided with a positioning hole 121, and the other of the support frame 51 and the leg 12 is provided with a positioning post 511, which is fitted into the positioning hole 121.

[0063] The cooperation between the positioning pin 511 and the positioning hole 121 enables the quick and accurate alignment of the mounting hole on the support leg 12 with the threaded hole on the support frame 51, thereby facilitating the rapid connection between the support leg 12 and the support frame 51 and improving the assembly efficiency of the robot torso device.

[0064] For example, such as Figures 1-4 As shown, each of the two diagonally opposite legs 12 is provided with a positioning hole 121, and the support frame 51 is provided with two corresponding positioning posts 511.

[0065] In some embodiments, the robot torso device further includes a shell 6, an air inlet duct 7, an air outlet duct 8, and a sealing ring 9. The shell 6 includes a first shell 61 and a second shell 62 opposite each other along a first direction. The first shell 61 has a second air inlet, and the second shell 62 has a second air outlet. A heat dissipation shell 1 is disposed between the first shell 61 and the second shell 62. The air inlet duct 7 is connected to the side of the heat dissipation shell 1 facing the first shell 61. A cooling fan 3 is connected to the side of the air inlet duct 7 facing the first shell 61. The second air inlet communicates with the first air inlet through the cooling fan 3 and the air inlet duct 7. The air outlet duct 8 is connected to the side of the heat dissipation shell 1 facing the second shell 62. The first air outlet communicates with the second air outlet through the air outlet duct 8. The sealing ring 9 is sandwiched between the air outlet duct 8 and the second shell 62.

[0066] When the cooling fan 3 is working, it draws outside air through the second air inlet, sequentially through the cooling fan 3, the air inlet duct 7, the heat dissipation channel, and the air outlet duct 8, and finally exhausts it to the outside through the second air outlet. The air inlet duct 7, the heat dissipation channel, and the air outlet duct 8 form a closed airflow system, greatly improving the working efficiency of the cooling fan 3 and further enhancing the overall efficiency of the cooling system. Furthermore, the sealing ring 9 ensures a good seal between the air outlet duct 8 and the second housing 62, and also effectively absorbs assembly tolerances.

[0067] For example, such as Figure 5 As shown, the sealing ring 9 is made of foam material. The air inlet duct 7 and the air outlet duct 8 both extend along the first direction. At this time, the duct formed between the second air inlet and the second air outlet is a straight-in-straight-out duct, which further reduces the air volume loss caused by the bend of the duct and further improves the heat dissipation efficiency of the heat source.

[0068] It should be noted that a fan cover is also provided on the side of the cooling fan 3 facing the first housing 61. The fan cover is connected to the cooling fan 3 by bolts to protect the cooling fan 3.

[0069] The robot according to the embodiments of the present invention includes a robot torso device as described in any of the above embodiments.
