[0041] like Figure 1-Figure 7As shown, according to the first aspect of an embodiment of the present application, a heat dissipation system is provided, including a main body 1 and a cover plate 2; the side wall of the main body 1 is provided with a plurality of first grooves 11 and a plurality of second grooves 12, the plurality of first grooves 11 are arranged at intervals along the axial direction of the main body 1, the first grooves 11 are arranged around the circumference of the main body 1, the plurality of second grooves 12 are arranged at intervals along the circumference of the main body 1, the second grooves 12 are arranged along the radial direction of the main body 1, and the second grooves 12 are connected to the first grooves 11; the cover plate 2 is provided on the main body 1, and the end surface 2a of the cover plate 2 away from the main body 1 is provided with a plurality of third grooves 21 and a plurality of fourth grooves 22, the plurality of third grooves 21 are arranged at intervals along the radial direction of the cover plate 2, the plurality of fourth grooves 22 are arranged at intervals along the circumference of the cover plate 2, and the fourth grooves 22 are connected to the third grooves 21.

[0042] The heat dissipation system of the present application is used in a joint module, and other components in the joint module are arranged inside the main body 1.

[0043] like Figure 4-Figure 7 As shown, the heat dissipation system includes a main body 1 and a cover plate 2; wherein, the cover plate 2 is arranged at one end of the main body 1, and the interior of the main body 1 is used to install other components of the joint module.

[0044] To further illustrate, the main body 1 can be cylindrical or cubic; preferably, the main body 1 is cylindrical, and the side wall of the main body 1 is located on the outer surface of the cylinder. A plurality of first grooves 11 and a plurality of second grooves 12 are provided on the side wall of the main body 1. The first grooves 11 are arranged in a ring around the circumference of the outer wall of the main body 1. The plurality of first grooves 11 are arranged at intervals along the axial direction of the main body 1. The second grooves 12 are extended along the axial direction of the main body 1. The plurality of second grooves 12 are arranged at intervals along the circumference of the main body 1. It can be understood that each second groove 12 can be connected to a part of the number of first grooves 11 or all of the number of first grooves 11 in the axial direction of the main body 1; therefore, the side wall of the main body 1 is also provided with the first groove 11 and the second groove 12 that are connected, and the first groove 11 and the second groove 12 also form a first air flow passage, and the outer wall of the main body 1 will also be provided with a first air flow passage. A plurality of first protrusions 13 are formed, and each first protrusion 13 has five faces, wherein the two opposite faces of two first protrusions 13 adjacent along the axial direction of the main body 1 are parallel, and the space between the two faces is part of the first groove 11, and the two opposite faces of two first protrusions 13 adjacent along the circumferential direction of the main body 1 intersect, and the space between the two faces is part of the second groove 12; therefore, through the plurality of first protrusions 13, the heat dissipation area and the circulation distance of the flowing air can be increased, and when the flowing air passes through the first air flow duct, it can also exchange heat with the five faces of each first protrusion 13, and the flow time is long, which can improve the heat dissipation effect of the joint module.

[0045] Further explanation, the cover plate 2 can be cylindrical or cubical. The shape of the cover plate 2 is the same as that of the body 1. Therefore, the shape of the cover plate 2 is preferably cylindrical; the cover plate 2 is arranged at one end of the body 1, and a plurality of third grooves 21 and a plurality of fourth grooves 22 are provided on the end face 2a of the cover plate 2 away from the body 1. The third groove 21 is annular, and the plurality of third grooves 21 are concentric and spaced apart along the radial direction of the end face 2a. It can be understood that the diameter of the third groove 21 gradually decreases from the center of the end face 2a to the edge of the end face 2a, that is, in the radial direction of the end face 2a. The fourth groove 22 is arranged to extend radially along the end surface 2a, and the plurality of fourth grooves 22 are arranged at intervals along the circumferential direction of the end surface 2a. It can be understood that each fourth groove 22 can be connected to a part of the third grooves 21 or the entire number of the third grooves 21 in the radial direction of the end surface 2a; therefore, the third groove 21 and the fourth groove 22 are connected and are provided on the end surface 2a. The third groove 21 and the fourth groove 22 form a second air flow passage, and a plurality of second protrusions 23 and a plurality of third protrusions 25 are also formed on the end surface 2a. The plurality of third protrusions 23 and the plurality of third protrusions 25 are also formed. The protrusions 25 are arranged at intervals around the circumference of the end face 2a, and the third protrusion 25 is located near the center of the end face 2a relative to the second protrusion 23; each second protrusion 23 has five faces, and each third protrusion 25 has four faces. The space formed between the two opposite faces of the two second protrusions 23 radially adjacent to the end face 2a is part of the third groove 21, and the space formed between the two opposite faces of the second protrusions 23 and the third protrusion 25 radially adjacent to the end face 2a is also part of the third groove 21. The space formed between the two opposite faces of the two second protrusions 23 circumferentially adjacent to the end face 2a is part of the fourth groove 22, and the space formed between the two opposite faces of the two third protrusions 25 circumferentially adjacent to the end face 2a is also part of the fourth groove 22; by means of multiple second protrusions 23 and multiple third protrusions 25, the heat dissipation area and the flow distance of the flowing air can be increased; when the flowing air flows from the first air flow duct to the second air flow duct, it can also exchange heat with the five faces of each second protrusion 23, and the flow time is long, which can improve the heat dissipation effect of the joint module.

[0046] The heat dissipation system of the present application is provided with a first groove 11 and a second groove 12 on the side wall of the main body 1, and a third groove 21 and a fourth groove 22 on the end face 2a of the cover plate 2. It has a simple structure and is easy to process. It does not occupy the internal space of the joint module and can also improve the heat dissipation effect.

[0047] In a specific embodiment, Figure 7As shown, along the radial direction of the main body 1, the cross-section of the second groove 12 is V-shaped; specifically, the second groove 12 includes a first side surface 121 and a second side surface 122, and the first side surface 121 and the second side surface 122 are both facing the interior of the second groove 12, and the first side surface 121 is also facing the second side surface 122, and one end of the first side surface 121 intersects with one end of the second side surface 122, and the other end of the second side surface 122 has a certain distance from the other end of the second side surface 122, so the cross-section of the second groove 12 in the radial direction of the main body 1 is V-shaped; wherein, the second groove 12 with a V-shaped cross-section can increase the heat dissipation area while exchanging heat with the flowing air coming from different directions, and will not generate a large flow resistance, thereby ensuring the flow rate of the flowing air to ensure the heat dissipation rate and heat dissipation effect.

[0048] In another specific embodiment, along the radial direction of the body 1 , the cross section of the second groove 12 may be U-shaped.

[0049] In an optional embodiment, the cross-section of the second groove 12 includes a first side surface 121 and a second side surface 122, one end of the first side surface 121 intersects with one end of the second side surface 122, and the distance between the other end of the first side surface 121 and the other end of the second side surface 122 is a first spacing H, and the width of the first side surface 121, the width of the second side surface 122 and the first spacing H are the same.

[0050] like Figure 7 As shown, the first side surface 121 includes a first end 1211 and a second end 1212, and the second side surface 122 includes a third end 1221 and a fourth end 1222; wherein, the first end 1211 of the first side surface 121 intersects with the third end 1221 of the second side surface 122, and the distance between the second end 1212 of the first side surface 121 and the fourth end 1222 of the second side surface 122 is a first spacing H.

[0051] The width of the first side surface 121 refers to the distance between the first end 1211 and the second end 1212 of the first side surface 121 , and the width of the second side surface 122 refers to the distance between the third end 1221 and the fourth end 1222 of the second side surface 122 .

[0052] Therefore, the width of the first side 121, the width of the second side 122 and the first spacing H are the same, so the radial cross-section of the second groove 12 in the main body 1 can be regarded as an equilateral triangle; in this embodiment, on the one hand, the three sides of the equilateral triangle are equal in length, the shape of the equilateral triangle is fixed, and it is not easy to deform. When the flowing air passes through the second groove 12, the pressure of the flowing air will act evenly on the first side 121 and the second side 122, thereby avoiding deformation of the second groove 12; on the other hand, when the flowing air passes through the second groove 12, due to its symmetrical shape, the air flow is relatively smooth, the flow path of the flowing air is relatively clear, and it is not easy to generate complex vortices, thereby further improving the heat dissipation rate.

[0053] In an alternative embodiment, Figure 7 As shown, the width of the first end 1211 surface, the width of the second end 1212 surface and the first spacing H are all between 2mm and 3mm; specifically, while ensuring a larger heat dissipation area, the structural strength of the second groove 12 can also be ensured to avoid deformation of the second groove 12.

[0054] In an optional embodiment, the spacing between two adjacent first grooves 11 is 1mm-3mm; wherein, the spacing between two adjacent first grooves 11, that is, the axial dimension of the surface of the first protrusion 13 that is not located in the first groove 11 and the second groove 12 in the body 1; specifically, the spacing between two adjacent first grooves 11 is between 1mm-3mm, which can ensure a larger heat dissipation area while also ensuring the structural strength of the first groove 11, avoiding deformation due to the small spacing between two adjacent first grooves 11.

[0055] In an optional embodiment, the depth of the first groove 11 is between 1mm and 3mm, and the depth of the second groove 12 is between 1mm and 3mm; the depth direction of the first groove 11 and the second groove 12 refers to the direction extending from the outer wall to the inner wall of the main body 1. In this embodiment, while ensuring the structural strength and heat dissipation area of the main body 1, there is no need to increase the thickness of the main body 1, thereby reducing the weight and volume of the joint module.

[0056] In a specific embodiment, the distance between two adjacent third grooves 21 is the same along the center of the end face 2a to the edge of the end face 2a; specifically, when the size of the joint module is small, the distance between two adjacent third grooves 21 can be the same, thereby ensuring the structural strength of the cover plate 2 and making processing more convenient.

[0057] In another specific embodiment, the distance between two adjacent third grooves 21 gradually increases from the center of the end face 2a to the edge of the end face 2a; specifically, when the size of the joint module is large, the distance between two adjacent third grooves 21 can be gradually increased, that is, the density of the third grooves 21 close to the center of the end face 2a is larger, and the density of the third grooves 21 away from the center of the end face 2a gradually decreases; when the joint module dissipates heat, the heat at the center of its cover plate 2 is higher than the heat at the edge of the cover plate 2, so while ensuring the structural strength of the cover plate 2, the heat dissipation effect of the center of the cover plate 2 can also be improved.

[0058] It is further explained that the volume of the second protrusion 23 gradually increases from the center of the end surface 2a to the edge of the end surface 2a, and the volume of the third protrusion 25 is smaller than the volume of the second protrusion 23; specifically, since the temperature in the central area of the cover plate 2 is higher, the volume of the second protrusion 23 and the third protrusion 25 near the center is smaller, which can reduce the accumulation of heat in the central area and enable the heat to be conducted to the edge of the end surface 2a more quickly. The second protrusion 23 near the edge of the end surface 2a is larger in volume and can provide a larger heat dissipation area. The heat dissipation conditions in the edge area are usually better than those in the central area because air flow can more easily reach the edge and the heat dissipation effect is more significant, thereby improving the efficiency of the heat dissipation system.

[0059] In an optional embodiment, the spacing between two adjacent third grooves 21 is 5mm-10mm; wherein, the spacing between two adjacent third grooves 21, that is, the radial dimension of the surface of the second protrusion 23 that is not located in the third groove 21 and the fourth groove 22 on the end surface 2a; specifically, the spacing between two adjacent third grooves 21 is between 5mm-10mm, which can ensure a larger heat dissipation area while also ensuring the structural strength of the third groove 21, thereby avoiding deformation due to a small spacing between two adjacent third grooves 21.

[0060] In a specific embodiment, along the axial direction of the cover plate 2 , the depth of the third groove 21 is 1 mm-3 mm.

[0061] In another specific embodiment, along the axial direction of the cover plate 2 , the depth of the fourth groove 22 is 1 mm-3 mm.

[0062] In another optional embodiment, along the axial direction of the cover plate 2, the depth of the third groove 21 is 1mm-3mm; the depth of the fourth groove 22 is 1mm-3mm; taking this embodiment as an example, specifically, the axial direction of the cover plate 2 is the same as the axial direction of the main body 1, and in the axial direction of the cover plate 2, the depth of the third groove 21 is between 1mm-3mm, and the depth of the fourth groove 22 is also between 1mm-3mm. In this embodiment, while ensuring the structural strength and heat dissipation area of the cover plate 2, there is no need to increase the axial dimension of the cover plate 2, thereby reducing the weight and volume of the joint module.

[0063] In an optional embodiment, the end face 2a is further provided with an avoidance groove 24, which is located at the center of the end face 2a. The diameter of the avoidance groove 24 is smaller than the diameter of the third groove 21. Each of the fourth grooves 22 is connected to the avoidance groove 24, and the extension line of the fourth groove 22 passes through the center of the end face 2a.

[0064] like Figure 6 As shown, an avoidance groove 24 is provided on the end face 2a. In the axial direction of the cover plate 2, the cross-section of the avoidance groove 24 is circular, and the diameter of the avoidance groove 24 is smaller than the diameter of the third groove 21. That is to say, the smallest third groove 21 will be arranged around the avoidance groove 24; the fourth groove 22 is arranged along the radial direction of the end face 2a. In addition to being connected to the third groove 21, the fourth groove 22 will also be connected to the avoidance groove 24, and the extension line of the fourth groove 22 will also pass through the center of the end face 2a, that is, the center of the avoidance groove 24; wherein, the flowing air first enters the avoidance groove 24, and then passes through each fourth groove 22 into the third groove 21, thereby flowing in the second air flow duct.

[0065] In an optional embodiment, the heat dissipation system also includes a shell 3 and a fan 4, the shell 3 includes an air inlet channel 31, an accommodating cavity 32 and a mounting hole 33, the air inlet channel 31 is connected to the accommodating cavity 32 through the mounting hole 33, the fan 4 is arranged in the mounting hole 33, the main body 1 and the cover plate 2 are arranged in the accommodating cavity 32, and the main body 1 and the cover plate 2 form a circulation channel 34 in the accommodating cavity 32 and the inner wall of the shell 3.

[0067] In an optional embodiment, the air inlet channel 31 includes a first inner wall 311 and a second inner wall 312 , and the first inner wall 311 and the second inner wall 312 are arranged opposite to each other along the axial direction of the housing 3 ;

[0068] A plurality of first partitions 313 and a plurality of second partitions 314 are provided in the air inlet channel 31, and a second partition 314 is provided between two adjacent first partitions 313. The first partition 313 is provided on the first inner wall 311, and there is a gap between the first partition 313 and the second inner wall 312. The second partition 314 is provided on the second inner wall 312, and there is a gap between the second partition 314 and the first inner wall 311.
