[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] The present invention provides a battery module combined heat dissipation device for a robot joint module, such as Figures 1 to 3As shown, it includes a robot shell 1, a heat dissipation component is provided on the front side of the robot shell 1, and the battery module is limited to the front side of the heat dissipation component by an installation component; the heat dissipation component includes: a microchannel cold plate 2, a heat dissipation plate 3 and multiple joint modules 4; the front side of the robot shell 1 is provided with a embedding groove 101 corresponding to the microchannel cold plate 2, the microchannel cold plate 2 is placed inside the embedding groove 101, and the heat dissipation plate 3 is correspondingly buckled on the front side of the microchannel cold plate 2, and multiple wristbands 301 and multiple foot rings 302 are provided at the bottom of the heat dissipation plate 3. The length of the wristband 301 can be adjusted accordingly according to the arrangement of the microchannel cold plate 2. The heat dissipation plate 3, wristband 301 and foot ring 302 cooperate to form a three-dimensional conformal heat spreader, and multiple wristbands 301 correspond one-to-one to multiple foot rings 302. The bottom of the heat dissipation plate 3 is connected to the foot ring 302 by the wristband 301, and the multiple foot rings 302 correspond one-to-one to the multiple joint modules 4, and the foot ring 302 is sleeved on the outside of the joint module 4. The robot housing 1 is provided with grooves 102 on both sides of its front side. The two grooves 102 correspond to the two wristbands 301, and the rear sides of the wristbands 301 are placed within the grooves 102. The foot rings 302 and wristbands 301 cooperate to form the foot wrist. The number of foot wrists in the three-dimensional accompanying heat spreader can be determined based on the heat dissipation requirements of the joint modules 4 within the robot. Each joint module 4 can correspond to a single foot wrist. The battery module is directly attached to the front side of the heat sink 3. The depth of the wristbands 301 embedded in the robot housing 1 is consistent with their thickness, that is, the thickness of the wristbands 301 is the same as the depth of the grooves 102.

[0020] The three-dimensional conformable heat spreader has an overall octopus-like, multi-legged shape. Foot rings 302 cover the entire radial outer surface of joint module 4. Foot rings 302 are connected to heat sink 3 via a long, ribbon-like wristband 301. The wristband 301 extends from foot rings 302 to the robot housing 1, then embeds into the inner layer of the robot housing 1 until it reaches heat sink 3. That is, wristband 301 connects to the bottom surface of heat sink 3 via slots 102. Heat sink 3 covers the entire front side of microchannel cold plate 2, which is embedded or semi-embedded within slots 101 of the robot housing 1. Both the three-dimensional conformable heat spreader and microchannel cold plate 2 are located on the inner side of the robot housing 1. The outer surface of the battery module can directly contact the front side of heat sink 3. All of these contacting areas are tightly attached by a layer of thermally conductive adhesive.

[0021] For example, the ratio of the lateral width of wristband 301 to the lateral width of footband 302 is maintained between 0.2 and 0.5, to achieve a balance between system lightweighting and heat dissipation. The thickness of the three-dimensional conformal heat sink is between 1mm and 3mm, to achieve a balance between heat dissipation performance and system lightweighting.

[0022] A three-dimensional conformable vapor chamber drives efficient, targeted heat transport, achieving centralized heat dissipation. The wrist-shaped design, while ensuring effective heat dissipation, reduces the complexity of the layout of the microchannel cold plate 2, battery module, and numerous joint modules 4 within the humanoid robot, reducing the energy consumption of the microchannel cold plate 2 and significantly increasing its flexibility within the humanoid robot. Furthermore, the embedded design of the microchannel cold plate 2 within the robot's housing 1 further enhances the system's lightweight design. The close fit between the robot housing 1, the heat sink 3, and the microchannel cold plate 2 significantly increases the heat dissipation surface area of ​​the robot housing 1, effectively improving heat dissipation efficiency.

[0023] exist Figure 3 and Figure 4 In the embodiment, the microchannel cold plate 2 includes a liquid inlet 201 and a liquid outlet 202, and a mesh groove 203 is provided inside the microchannel cold plate 2. The liquid inlet 201 is connected to the liquid outlet 202 via the mesh groove 203, and the liquid inlet 201 and the liquid outlet 202 are equal in size. Exemplarily, the thickness of the microchannel cold plate 2 is between 1 cm and 1.5 cm to achieve a balance between heat dissipation performance, mechanical performance and system lightweight. The microchannel cold plate 2 is configured as a square structure, and the liquid inlet 201 and the liquid outlet 202 are both configured to open in the positive direction. The size ratio of the liquid inlet 201 width to the thickness of the microchannel cold plate 2 is maintained between 0.4 and 0.7 to achieve a balance between heat dissipation effect and mechanical performance.

[0024] The liquid inlet 201 is located on the right side of the microchannel cold plate 2, and the liquid outlet 202 is located on the left side of the microchannel cold plate 2. External coolant is introduced into the mesh groove 203 through the liquid inlet 201. The coolant is distributed throughout the entire microchannel cold plate 2 through the mesh groove 203, ensuring that the temperature of the entire microchannel cold plate 2 is reduced, making it easier for the entire microchannel cold plate 2 to absorb the heat of the three-dimensional conformal heat spreader. The coolant passing through the mesh groove 203 is discharged through the liquid outlet 202, and the coolant discharged from the liquid outlet 202 is received.

[0025] exist Figure 1 、 Figure 3 、 Figure 5 and Figure 6In the figure, the installation assembly includes: a press frame 5, an insertion rod 6, a first elastic member 7 and a nut 8; the press frame 5 is located on the front side of the heat sink 3, and a plurality of insertion rods 6 are fixed to the front side of the robot housing 1. The insertion rods 6 correspond to the corners of the press frame 5, and the surface of the insertion rods 6 is sleeved with the first elastic member 7. The first elastic member 7 is configured as a spring. The front end of the first elastic member 7 fits with the rear side of the press frame 5, and the rear end of the first elastic member 7 fits with the front side of the robot housing 1. The nut 8 is screwed onto the front end of the insertion rod 6. The press frame 5 includes two horizontal plates 501 and two vertical plates 502. The ends of the horizontal plates 501 are connected to the ends of the vertical plates 502. The rear sides of the vertical plates 502 correspond to the front side of the heat sink 3. A horizontal groove is provided at the center of the horizontal plate 501, and a plug-in component is inserted into the horizontal groove. The plug-in component uses a pressure strip 9 to make the battery module fit on the front side of the heat sink 3. The microchannel cold plate 2 is placed inside the embedding groove 101, and the heat sink 3 of the three-dimensional conformal heat spreader is snapped onto the outside of the microchannel cold plate 2. The pressing frame 5 corresponds to the heat sink 3. At this time, the four corners of the pressing frame 5 correspond one-to-one with multiple insertion rods 6. The pressing frame 5 is pushed close to the robot housing 1. The corners of the pressing frame 5 are gradually sleeved on the surface of the insertion rod 6. The pressing frame 5 squeezes the first elastic member 7 on the surface of the insertion rod 6, and the nut 8 is screwed onto the front end of the insertion rod 6. The rotating nut 8 cooperates with the screw of the insertion rod 6, thereby making the pressing frame 5 close to the robot housing 1.

[0026] The backward-moving pressure frame 5 drives the vertical plate 502 to approach the heat sink 3 until the rear side of the vertical plate 502 is in contact with the front side of the heat sink 3. The screw fit of the nut 8 and the insertion rod 6 is used to improve the stability of the heat sink 3 and the microchannel cold plate 2 on the front side of the robot housing 1.

[0027] The battery module includes multiple battery cells 10 and clips 11; the multiple battery cells 10 are arranged side by side inside the press frame 5, and the clips 11 are correspondingly snapped onto the outside of the multiple battery cells 10. The ends of the clips 11 are connected to the clips 9 using bolt assemblies. When the heat sink 3 is completely defined, the multiple battery cells 10 are arranged side by side inside the press frame 5, with the rear sides of the battery cells 10 aligned with the front side of the heat sink 3. The clips 9 are installed on the front side of the plug-in component, so that the multiple battery cells 10 are located between the two clips 9. The clips 11 are snapped onto the front sides of the multiple battery cells 10, and the ends of the clips 11 are connected to the clips 9 using bolt assemblies as in the prior art.

[0028] exist Figure 3 、 Figures 6 to 8In the embodiment, the plug-in component includes: a moving rod 12, a bottom ring 13, a locking portion and a fastening sleeve 14; the moving rod 12 passes through the transverse groove, a circular plate 121 is fixed to the rear side of the moving rod 12, an annular groove 122 is provided on the outer circumference of the circular plate 121, the bottom ring 13 is rotatably sleeved on the outer side of the annular groove 122, the rear end of the locking portion is connected to the front side of the bottom ring 13, the rear side of the transverse plate 501 is provided with a limiting groove 503 corresponding to the locking portion, and the front end of the locking portion is inserted into the limiting groove 503. When the moving rod 12 is pushed to move, the moving rod 12 moves horizontally inside the transverse groove of the transverse plate 501, and the moving rod 12 uses the circular plate 121 to drive the bottom ring 13 to move synchronously. The bottom ring 13 causes the front side of the locking portion to move inside the limiting groove 503. The limiting groove 503 uses the locking portion to limit the bottom ring 13, preventing the bottom ring 13 from rotating outside the annular groove 122 and preventing the moving rod 12 from tilting inside the transverse groove.

[0029] Since the end of the pressure strip 9 is sleeved on the front end of the moving rod 12, the fastening sleeve 14 and the spiral cooperation of the moving rod 12 limit the pressure strip 9. The moving rod 12 is moved by pushing, and the moving rod 12 drives the pressure strip 9 to move synchronously until the pressure strip 9 contacts the battery cell 10. The clamping strip 11 is connected to the pressure strip 9 through a bolt assembly, which is convenient for connecting battery modules of different widths between the two pressure strips 9, thereby improving the adaptability of the heat sink 3 to different battery modules.

[0030] The locking portion includes: a support rod 15, a sleeve 16, a second elastic member 17 and a clamp 18, the second elastic member 17 is configured as a spring sheet; the rear end of the support rod 15 is fixedly connected to the front side of the bottom ring 13, the rear end of the sleeve 16 is sleeved on the front end of the support rod 15, the rear end of the sleeve 16 is connected to the front side of the bottom ring 13 by the second elastic member 17, the front end of the sleeve 16 is fixed with a clamp 18, and the clamp 18 is clamped inside the limiting groove 503. When the moving rod 12 moves, the moving rod 12 uses the bottom ring 13 to make the clamping head 18 of the locking part move inside the limiting groove 503. After the moving rod 12 moves to a suitable position, the moving rod 12 is limited and the fastening sleeve 14 is rotated. The rotating fastening sleeve 14 and the spiral cooperation of the moving rod 12 make the bottom ring 13 close to the horizontal plate 501. The forward-moving bottom ring 13 makes the front end of the support rod 15 gradually enter the interior of the sleeve 16, and the forward-moving bottom ring 13 cooperates with the sleeve 16 to squeeze the second elastic member 17 until the rear side of the pressure strip 9 is in contact with the front side of the heat sink 3, further improving the tightness of the heat sink 3 and the robot housing 1.

[0031] When the rear side of the pressure strip 9 is fitted with the front side of the heat dissipation plate 3 through the spiral cooperation between the fastening sleeve 14 and the moving rod 12, the moving rod 12 is loosened, and the rotating fastening sleeve 14 drives the moving rod 12 to rotate. The rotating moving rod 12 causes the circular plate 121 to rotate inside the bottom ring 13, preventing the pressure strip 9 from excessively squeezing the front side of the robot housing 1, and the elastic force of the second elastic member 17 causes the fastening sleeve 14 to squeeze the end of the pressure strip 9, preventing the end of the pressure strip 9 from moving arbitrarily on the surface of the horizontal plate 501, thereby improving the stability of the battery module inside the pressure frame 5.

[0032] Working principle of the present invention: Reference Figures 1 to 8 As shown, the microchannel cold plate 2 is placed inside the embedding groove 101, the heat sink 3 of the three-dimensional conformal heat spreader is snapped onto the outside of the microchannel cold plate 2, and the pressing frame 5 corresponds to the heat sink 3. At this time, the four corners of the pressing frame 5 correspond one-to-one with multiple insertion rods 6, pushing the pressing frame 5 close to the robot housing 1, and the corners of the pressing frame 5 are gradually sleeved on the surface of the insertion rod 6. The pressing frame 5 squeezes the first elastic member 7 on the surface of the insertion rod 6, and the nut 8 is screwed onto the front end of the insertion rod 6. The rotating nut 8 cooperates with the spiral of the insertion rod 6, thereby making the pressing frame 5 close to the robot housing 1.

[0033] The backward-moving pressure frame 5 drives the vertical plate 502 to approach the heat sink 3 until the rear side of the vertical plate 502 is in contact with the front side of the heat sink 3. The screw fit of the nut 8 and the insertion rod 6 is used to improve the stability of the heat sink 3 and the microchannel cold plate 2 on the front side of the robot housing 1.

[0034] The microchannel cold plate 2 is embedded or semi-embedded in the embedding groove 101 of the robot housing 1, the heat sink 3 covers the entire front side of the microchannel cold plate 2, the foot ring 302 covers the entire radial outer surface of the joint module 4, and the foot ring 302 is connected to the heat sink 3 through a long strip-shaped wristband 301; the wristband 301 extends from the foot ring 302 to the robot housing 1, and then is embedded in the inner layer of the robot housing 1 until it reaches the heat sink 3, that is, the wristband 301 is connected to the bottom surface of the heat sink 3 through the groove 102.

[0035] The movable rod 12 is pushed to move, and the movable rod 12 moves horizontally inside the transverse groove of the transverse plate 501. The movable rod 12 uses the circular plate 121 to drive the bottom ring 13 to move synchronously. The bottom ring 13 makes the front side of the locking portion move inside the limiting groove 503. The limiting groove 503 uses the locking portion to limit the bottom ring 13, preventing the bottom ring 13 from rotating outside the annular groove 122, and at the same time preventing the movable rod 12 from tilting inside the transverse groove.

[0036] When the moving rod 12 moves, the moving rod 12 uses the bottom ring 13 to make the clamping head 18 of the locking part move inside the limiting groove 503. After the moving rod 12 moves to a suitable position, the moving rod 12 is limited and the fastening sleeve 14 is rotated. The rotating fastening sleeve 14 and the spiral cooperation of the moving rod 12 make the bottom ring 13 close to the horizontal plate 501. The forward-moving bottom ring 13 makes the front end of the support rod 15 gradually enter the interior of the sleeve 16, and the forward-moving bottom ring 13 cooperates with the sleeve 16 to squeeze the second elastic member 17 until the rear side of the pressure strip 9 is in contact with the front side of the heat sink 3, further improving the tightness of the heat sink 3 and the robot housing 1.

[0037] Since the end of the pressure strip 9 is sleeved on the front end of the moving rod 12, the fastening sleeve 14 and the spiral cooperation of the moving rod 12 limit the pressure strip 9. The moving rod 12 is moved by pushing, and the moving rod 12 drives the pressure strip 9 to move synchronously until the pressure strip 9 contacts the battery cell 10. The clamping strip 11 is connected to the pressure strip 9 through a bolt assembly, which is convenient for connecting battery modules of different widths between the two pressure strips 9, thereby improving the adaptability of the heat sink 3 to different battery modules.

[0038] The external coolant is introduced into the mesh groove 203 through the liquid inlet 201, and the coolant is distributed throughout the entire microchannel cold plate 2 through the mesh groove 203, ensuring that the temperature of the entire microchannel cold plate 2 is reduced, making it easier for the entire microchannel cold plate 2 to absorb the heat of the three-dimensional conformal heat spreader. The coolant passing through the mesh groove 203 is discharged through the liquid outlet 202, and the coolant discharged from the liquid outlet 202 is received.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
