[0047] Labeling: Heat dissipation module 1, housing 10, lattice structure 20, heat dissipation channel 201, first lattice sub-section 21, first spacer 211, second spacer 212, second lattice sub-section 22, third spacer 221, third lattice sub-section 23, fourth spacer 231, fourth lattice sub-section 24, fifth spacer 241, sixth spacer 242, heating element 2. Detailed Implementation

[0048] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0049] In view of this, in order to solve the above problems, please refer to the following: Figures 1-5 This embodiment provides a heat dissipation module 1, which includes a housing 10 and a lattice structure 20 disposed within the housing 10. The lattice structure 20 includes a plurality of stacked lattice sub-parts, each of which has a plurality of heat dissipation sub-channels arranged at intervals along a direction perpendicular to the stacking direction of the lattice structure 20. The arrangement directions of the heat dissipation sub-channels of two adjacent lattice sub-parts are different.

[0050] Along the stacking direction of the lattice structure 20, the heat dissipation sub-channels of the plurality of lattice sub-parts are sequentially connected to form a heat dissipation channel 201 that penetrates the housing 10, and the heat dissipation channel 201 is used for the flow of cooling gas.

[0051] The heat dissipation module 1 is used to dissipate heat from the heat-generating component 2. Specifically, the heat dissipation module 1 is located on one side of the heat-generating component 2 and absorbs the heat energy of the heat-generating component 2. Cooling gas flows through the heat dissipation channel 201 of the heat dissipation module 1 and carries away the heat energy on the heat dissipation module 1, thereby realizing the heat dissipation function of the heat dissipation module 1.

[0052] like Figures 1-2 As shown, the heat dissipation module 1 can be applied to a motor. For example, the motor includes an iron core and a coil winding, with the coil winding surrounding the iron core. The heat dissipation module 1 is located on one side of the iron core and the coil winding. Furthermore, the housing 10 of the heat dissipation module 1 contacts the iron core, thereby improving the heat conduction efficiency and enhancing the heat dissipation effect of the heat dissipation module 1. Optionally, the motor is installed in a drone.

[0053] In addition to motors, heat dissipation module 1 can also be used in other fields, such as electronic equipment, vehicles, energy, and industrial manufacturing.

[0054] The housing 10 has a through hole that extends along the thickness direction of the housing 10; in other words, the housing 10 has a through hole that penetrates the housing 10 along its thickness direction. A lattice structure 20 is disposed within the through hole and communicates with the outside. Optionally, the housing 10 and the lattice structure 20 are an integral structural component.

[0055] The lattice structure 20 includes stacked lattice sub-sections, wherein the stacking direction of the lattice structure 20 is the thickness direction of the shell 10. The number of lattice sub-sections can be set according to product requirements; optionally, the number of lattice sub-sections can be at least two, at least three, or at least four.

[0056] like Figure 3 , Figure 4 , Figure 5 As shown, each lattice sub-section has multiple heat dissipation sub-channels, at least some of which penetrate the lattice sub-section along the stacking direction of the lattice structure 20. Furthermore, the heat dissipation sub-channels of adjacent lattice sub-sections have different arrangement directions. For example, the heat dissipation sub-channels of one lattice sub-section may be arranged in an array, or the heat dissipation sub-channels of another lattice sub-section may be arranged tilted to the left, or the heat dissipation sub-channels of yet another lattice sub-section may be arranged tilted to the right, etc.

[0057] Along the stacking direction of the lattice structure 20, heat dissipation sub-channels of adjacent lattice sub-sections are interconnected, thereby forming a heat dissipation channel 201 that penetrates the housing 10 along the stacking direction of the lattice structure 20. Cooling gas can flow through the heat dissipation channel 201 and carry away the heat energy on each lattice sub-section. Optionally, the cooling gas is air. The stacking direction of the lattice structure 20 is as follows: Figure 4 and Figure 5 The direction is shown in D1.

[0058] In summary, the heat dissipation module 1 provided in this embodiment uses a lattice structure 20 formed by multiple lattice sub-parts as a heat sink, which increases the heat dissipation surface of the heat dissipation module 1 and ensures that the heat dissipation channel 201 has sufficient flow space. Furthermore, by limiting the arrangement direction of the heat dissipation sub-channels of two adjacent lattice sub-parts to be different, a heat dissipation channel 201 composed of heat dissipation sub-channels of different shapes is obtained, which is conducive to the formation of turbulence of cooling gas, thereby improving the heat dissipation effect of the heat dissipation module 1.

[0059] Please refer to this as well. Figures 1-6 In one embodiment, the plurality of lattice sub-sections include a first lattice sub-section 21 and a second lattice sub-section 22. The first lattice sub-section 21 includes a plurality of first spacer bars 211 spaced apart along a first direction and a plurality of second spacer bars 212 spaced apart along a second direction, wherein the first direction and the second direction are angled together, and the plurality of first spacer bars 211 and the plurality of second spacer bars 212 are connected to form the plurality of heat dissipation sub-channels arranged in an array.

[0060] The second lattice sub-section 22 is disposed adjacent to the first lattice sub-section 21. The first spacer 211 and the second spacer 212 have a first interaction point. The second lattice sub-section 22 includes a plurality of third spacer 221 arranged at intervals along a third direction. Each third spacer 221 is sequentially connected to a plurality of first interaction points arranged diagonally. The third direction is arranged at an angle to the first direction and the second direction. The plurality of heat dissipation sub-channels are formed between the plurality of third spacer 221.

[0061] Specifically, the angle between the first direction and the second direction is 70° to 110°, and can be exemplified by 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, or 110°, etc. Preferably, the angle between the first direction and the second direction is 90°.

[0062] And / or, the angle between the third direction and the first direction is 30° to 60°, specifically, for example, 30°, 35°, 40°, 45°, 50°, 55°, or 60°, etc. Preferably, the angle between the third direction and the first direction is 45°.

[0063] And / or, the angle between the third direction and the second direction is 30° to 60°, specifically, for example, 30°, 35°, 40°, 45°, 50°, 55°, or 60°, etc. Preferably, the angle between the third direction and the second direction is 45°.

[0064] like Figure 6As shown, in the first lattice sub-section 21, a first spacer 211 passes through and connects to a second spacer 212, and a second spacer 212 passes through and connects to the first spacer 211, thereby forming multiple heat dissipation sub-channels arranged in an array. The heat dissipation sub-channels of the first lattice sub-section 21 are formed by the first spacer 211 and the second spacer 212 enclosing each other.

[0065] The second lattice sub-section 22 is disposed adjacent to the first lattice sub-section 21. For example, the second lattice sub-section 22 is located above the first lattice sub-section 21. Alternatively, the second lattice sub-section 22 may be located below the first lattice sub-section 21. In the second lattice sub-section 22, a plurality of third spacer bars 221 are arranged at intervals, and the third spacer bars 221 are sequentially connected to a plurality of first interaction points arranged diagonally. The heat dissipation sub-channel of the second lattice sub-section 22 is formed by two adjacent third spacer bars 221.

[0066] The quantity, spacing, and thickness of the first spacer 211, the second spacer 212, and the third spacer 221 can be adjusted according to product requirements. Optionally, the number of the first spacer 211 is equal to the number of the second spacer 212, or the number of the first spacer 211 is not equal to the number of the second spacer 212.

[0067] Optionally, the spacing between adjacent first spacers 211 is equal, the spacing between adjacent second spacers 212 is equal, and the spacing between adjacent third spacers 221 is equal; or, the spacing between at least some of the adjacent first spacers 211 is unequal, the spacing between at least some of the adjacent second spacers 212 is unequal, and the spacing between at least some of the adjacent third spacers 221 is unequal.

[0068] Optionally, the thickness of the plurality of first spacers 211 is equal, the thickness of the plurality of second spacers 212 is equal, and the thickness of the plurality of third spacers 221 is equal; or, at least some of the thickness of the plurality of first spacers 211 is unequal, at least some of the thickness of the plurality of second spacers 212 is unequal, and at least some of the thickness of the plurality of third spacers 221 is unequal.

[0069] Furthermore, such as Figure 6 As shown, the plurality of lattice sub-parts include a third lattice sub-part 23, which is disposed on the side of the first lattice sub-part 21 away from the second lattice sub-part 22. The third lattice sub-part 23 includes a plurality of fourth spacer bars 231 arranged at intervals along a fourth direction. Each fourth spacer bar 231 is sequentially connected to a plurality of first interaction points arranged diagonally. The fourth direction is angularly arranged with respect to the first direction, the second direction, and the third direction. The plurality of heat dissipation sub-channels are formed between the plurality of fourth spacer bars 231.

[0070] Specifically, the angle between the fourth direction and the first direction is 30° to 60°, and can be exemplified by 30°, 35°, 40°, 45°, 50°, 55°, or 60°, etc. Preferably, the angle between the fourth direction and the first direction is 45°.

[0071] And / or, the angle between the fourth direction and the second direction is 30° to 60°, specifically, for example, 30°, 35°, 40°, 45°, 50°, 55°, or 60°, etc. Preferably, the angle between the fourth direction and the second direction is 45°.

[0072] And / or, the angle between the fourth direction and the third direction is 70°~110°, such as 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, or 110°. Preferably, the angle between the fourth direction and the third direction is 90°.

[0073] In the third lattice sub-section 23, a plurality of fourth spacer bars 231 are arranged at intervals, and the fourth spacer bars 231 are sequentially connected to a plurality of first interaction points arranged diagonally. The heat dissipation sub-channel of the third lattice sub-section 23 is formed by two adjacent fourth spacer bars 231.

[0074] Optionally, the plurality of lattice sub-sections may further include a fourth lattice sub-section 24, which is disposed on the side of the third lattice sub-section 23 away from the first lattice sub-section 21, or disposed on the side of the second lattice sub-section 22 away from the first lattice sub-section 21.

[0075] The fourth lattice sub-section 24 includes a plurality of fifth spacer bars 241 spaced apart along a first direction and a plurality of sixth spacer bars 242 spaced apart along a second direction. The plurality of fifth spacer bars 241 and the plurality of sixth spacer bars 242 are connected to form the plurality of heat dissipation sub-channels arranged in an array.

[0076] The fifth spacer 241 and the sixth spacer 242 have a second interaction point. When the fourth lattice sub-section 24 is located on the side of the third lattice sub-section 23 away from the first lattice sub-section 21, each fourth spacer 231 is sequentially connected to a plurality of second interaction points arranged diagonally. When the fourth lattice sub-section 24 is located on the side of the second lattice sub-section 22 away from the first lattice sub-section 21, each third spacer 221 is sequentially connected to a plurality of second interaction points arranged diagonally.

[0077] In the fourth lattice sub-section 24, the fifth spacer 241 passes through and connects to the sixth spacer 242, and the sixth spacer 242 passes through and connects to the fifth spacer 241, thereby forming multiple heat dissipation sub-channels arranged in an array. The heat dissipation sub-channels of the fourth lattice sub-section 24 are formed by the fifth spacer 241 and the sixth spacer 242. Optionally, the fifth spacer 241 is directly opposite to the first spacer 211, and the sixth spacer 242 is directly opposite to the second spacer 212; or, at least some of the fifth spacer 241 and the first spacer 211 are staggered, and at least some of the sixth spacer 242 and the second spacer 212 are staggered.

[0078] For example, the third lattice section 23, the first lattice section 21, and the second lattice section 22 are arranged in sequence.

[0079] For example, the fourth lattice section 24, the third lattice section 23, the first lattice section 21, and the second lattice section 22 are arranged in sequence.

[0080] For example, the third lattice section 23, the first lattice section 21, the second lattice section 22, and the fourth lattice section 24 are arranged in sequence.

[0081] The quantity, spacing, and thickness of the fourth spacer 231, the fifth spacer 241, and the sixth spacer 242 can be adjusted according to product requirements. Optionally, the quantity of the fifth spacer 241 is equal to the quantity of the sixth spacer 242, or the quantity of the fifth spacer 241 is not equal to the quantity of the sixth spacer 242.

[0082] Optionally, the spacing between adjacent fourth spacers 231 is equal, the spacing between adjacent fifth spacers 241 is equal, and the spacing between adjacent sixth spacers 242 is equal; or, the spacing between at least some of the adjacent fourth spacers 231 is unequal, the spacing between at least some of the adjacent fifth spacers 241 is unequal, and the spacing between at least some of the adjacent sixth spacers 242 is unequal.

[0083] Optionally, the thickness of the plurality of fourth spacers 231 is equal, the thickness of the plurality of fifth spacers 241 is equal, and the thickness of the plurality of sixth spacers 242 is equal; or, the thickness of at least some of the plurality of fourth spacers 231 is unequal, the thickness of at least some of the plurality of fifth spacers 241 is unequal, and the thickness of at least some of the plurality of sixth spacers 242 is unequal.

[0084] Therefore, by setting the first lattice sub-section 21, the second lattice sub-section 22, and the third lattice sub-section 23, this embodiment obtains lattice sub-sections with different heat dissipation sub-channels, which not only increases the heat dissipation surface of the heat dissipation module 1, but also ensures that the heat dissipation channel 201 has sufficient flow space, and also helps to form turbulence of cooling gas, thereby improving the heat dissipation effect of the heat dissipation module 1.

[0085] Please refer to this as well. Figures 1-12 In one embodiment, the heat dissipation module 1 is arranged in a ring shape. The first spacer 211 extends along the circumferential direction of the heat dissipation module 1, the first direction being the radial direction of the heat dissipation module 1, and the center of the plurality of first spacer 211 is the same as the center of the heat dissipation module 1. The second spacer 212 extends along the radial direction of the heat dissipation module 1, the second direction being the circumferential direction of the heat dissipation module 1. The third spacer 221 is arc-shaped, and the extension lines of the plurality of third spacer 221 converge at the center of the heat dissipation module 1.

[0086] The center of heat dissipation module 1 is as follows Figure 15 As shown at midpoint O.

[0087] For example, there is one heat dissipation module 1, and the heat dissipation module 1 is arranged in a ring.

[0088] For example, there are multiple heat dissipation modules 1, which are spaced apart and arranged in a ring.

[0089] like Figures 7-9 As shown, a plurality of first spacer bars 211 are arranged in a semi-circular or circular shape, and the plurality of first spacer bars 211 have the same center, which is the same as the center of the heat dissipation module 1. A plurality of second spacer bars 212 extend along the radial direction of the heat dissipation module 1, wherein, along the direction away from the center, the gap between two adjacent second spacer bars 212 gradually increases.

[0090] like Figure 7 , Figure 10 As shown, the third spacer 221 sequentially connects multiple first interaction points arranged diagonally, and the extension lines of the multiple third spacer 221 converge at the same point. It can also be understood that the third spacer 221 is vortex-shaped.

[0091] Furthermore, the fourth spacer 231 is arc-shaped, and the extension lines of the plurality of fourth spacers 231 converge at the center of the heat dissipation module 1. The bending direction of the fourth spacer 231 is opposite to the bending direction of the third spacer 221.

[0092] like Figure 8 , Figure 11 As shown, the fourth spacer 231 sequentially connects multiple first interaction points arranged diagonally, and the extension lines of the multiple fourth spacer 231 converge at the same point. It can also be understood that the fourth spacer 231 is vortex-shaped.

[0093] like Figure 12As shown, optionally, the fifth spacer 241 extends along the circumferential direction of the heat dissipation module 1, the center of the plurality of fifth spacers 241 is the same as the center of the heat dissipation module 1, and the sixth spacer 242 extends along the radial direction of the heat dissipation module 1.

[0094] Multiple fifth spacer bars 241 are arranged in a semi-circular or circular shape, and the multiple fifth spacer bars 241 have the same center, which is the same as the center of the heat dissipation module 1. Multiple sixth spacer bars 242 extend along the radial direction of the heat dissipation module 1, wherein the gap between two adjacent sixth spacer bars 242 gradually increases along the direction away from the center.

[0095] Therefore, by further defining the arrangement of the first spacer 211, the second spacer 212, the third spacer 221, and the fourth spacer 231, this embodiment is more conducive to forming turbulence in the cooling gas, thereby further improving the heat dissipation effect of the heat dissipation module 1.

[0096] Please refer to Figure 13 In another embodiment, the lattice structure 20 satisfies at least one of the following conditions in a Cartesian coordinate system:

[0097] f1(x,y,z)=sin(Ax)×cos(By)+sin(By)×cos(Cz)+sin(Cz)×cos(Ax)-t.

[0098] f2(x,y,z)=sin(Ax)×sin(By)×sin(Cz)+sin(Ax)×cos(By)×cos(Cz)+cos(Ax)×sin(By)×cos(Cz)+cos×(Ax)×cos(By)×sin(Cz)-t.

[0099] f3(x,y,z)=cos(Ax)+cos(By)+cos(Cz)-t.

[0100] f4(x,y,z)=2[cos(Ax)×cos(By)+cos(By)×cos(Cz)+cos(Cz)×cos(Ax)]-[cos(2Ax)+cos(2By)+ cos(2Cz)]-t.

[0101] Where f1(x,y,z), f2(x,y,z), f3(x,y,z), and f4(x,y,z) are the relationships of lattice structures of different shapes, x, y, and z are the coordinates of the lattice structure 20 in the rectangular coordinate system, A is the correlation coefficient of the number of array periods of the lattice structure 20 in the x direction, B is the correlation coefficient of the number of array periods of the lattice structure 20 in the y direction, C is the correlation coefficient of the number of array periods of the lattice structure 20 in the z direction, and t is the thickness of the spacer strip in the lattice structure 20.

[0102] Different coordinate relationships and different parameters can generate lattice structures of various shapes.20 f1(x,y,z), f2(x,y,z), f3(x,y,z), and f4(x,y,z) can correspond to... Figure 13 Any one of the crystal lattice structures 20 is used here for illustration only.
