[0056] Embodiment 1

[0057] like Figure 1 to Figure 4 As shown, this embodiment provides a heat sink, which includes a heat spreader 100, which is used to install a heating element and fix the heating element. The heating element here can be any structure that can generate heat during operation, such as a lamp, an electronic component, etc.

[0058] In one embodiment, in order to improve the heat dissipation effect of the radiator, as Figure 2 As shown, the heat spreader 100 is a heat conducting plate as a whole, so that the heat spreader 100 has the effect of evenly distributing the heat of the heating element, and can also quickly conduct the heat generated by the heating element, thereby improving the thermal conductivity efficiency.

[0059] In other embodiments, Figure 3 As shown, in order to improve the heat absorption and heat conduction efficiency of the heat spreader 100. In this embodiment, the heat spreader 100 includes a main body 110 and a plurality of heat spreaders 120. The main body 110 is provided with a receiving groove along which a plurality of heat spreaders 120 extend along the X direction (first direction), and a plurality of heat spreaders 120 are arranged in parallel and in contact with each other along the Y direction (second direction). Among them, the X direction and the Y direction are perpendicular to each other. Since the heat spreader 120 uses the principle of capillary phenomenon to absorb and conduct heat, the structure of the heat spreader 100 greatly improves the efficiency of absorbing heat from the heating element. At the same time, the plurality of heat spreaders 120 are arranged in parallel and in contact with each other, which is conducive to mutual heat conduction between the plurality of heat spreaders 120, and is conducive to ensuring the temperature balance at different positions of the heat spreader 100, thereby achieving the effect of equalizing heat.

[0060] Optionally, the cross-sectional shape of the heat equalizing tube 120 is square. In this case, two adjacent heat equalizing tubes 120 can be in surface contact with each other. Compared with the commonly used heat equalizing tubes 120 with circular cross-sections, the contact area is larger, which is beneficial to reducing thermal resistance and improving heat conduction and heat equalization effects.

[0061] Further, the cross-sectional dimensions of the heat-scaling tube 120 are (3mm to 5mm)×(10mm to 14mm). Specifically, the thickness of the heat-scaling tube 120 along the Y direction may be 3mm to 5mm, and the thickness of the heat-scaling tube 120 along the Z direction (third direction) may be 10mm to 14mm. Among them, the X direction, the Y direction, and the Z direction are arranged vertically in pairs. The cross-sectional area of ​​the heat-scaling tube 120 is large, which is beneficial to improving the thermal conductivity. At the same time, the thickness of the heat-scaling tube 120 along the Z direction is greater than the thickness along the Y direction, which is beneficial to increase the contact area of ​​adjacent heat-scaling tubes 120, and further ensure the heat conduction effect between adjacent heat-scaling tubes 120. In another embodiment, specifically, the thickness of the heat-scaling tube 120 along the Z direction may be 3mm to 5mm, and the thickness of the heat-scaling tube 120 along the Y direction (third direction) may be 10mm to 14mm. The surface area of ​​the heat-scaling tube 120 in contact with the heating element is increased, which is beneficial to ensure the heat absorption efficiency.

[0062] Furthermore, if Figure 4 and Figure 5 As shown, the radiator further includes a first heat pipe assembly 200, which is a plurality of groups. The plurality of groups of first heat pipe assemblies 200 are arranged in parallel along the X direction, so that the user can flexibly select the number of first heat pipe assemblies 200 according to the heat of the heating element, thereby expanding the application range of the radiator. For example, in this embodiment, the first heat pipe assembly 200 is 10 groups, so that the radiator can achieve high-power heat dissipation.

[0063] Among them, see Figure 5 Each group of first heat pipe assemblies 200 includes a plurality of first heat pipes 210, and the first heat pipes 210 are of a U-shaped structure. The first heat pipes 210 include a first heat conducting portion 211, a connecting portion 212, and a second heat conducting portion 213 of a U-shaped structure. The first heat conducting portion 211 extends along the Y direction and abuts against the heat spreader 100. The connecting portion 212 is respectively connected to both ends of the first heat conducting portion 211, and the second heat conducting portion 213 is respectively connected to the connecting portions 212 on both sides, so that the first heat conducting portion 211 absorbs heat from the heat spreader 100 and conducts it to both sides, and then conducts it to the second heat conducting portion 213 through the connecting portion 212.

[0064] Illustratively, in this embodiment, each group of first heat pipe assemblies 200 includes four first heat pipes 210 , that is, each group of first heat pipe assemblies 200 includes eight second heat conducting parts 213 , and the eight second heat conducting parts 213 conduct heat together, which is beneficial to improving heat conduction efficiency.

[0065] The multiple second heat conducting parts 213 of each group of first heat pipe assemblies 200 are arranged on the same plane, which is conducive to saving space, facilitating the arrangement of the structure, and improving the aesthetics of the arrangement of the first heat pipe assemblies 200. The connecting part 212 is bent according to the relative position of the first heat conducting part 211 and the second heat conducting part 213. The multiple second heat conducting parts 213 of two adjacent groups of first heat pipe assemblies 200 are arranged at intervals, and an accommodating space 220 for arranging the first heat dissipation assembly 300 is formed. The first heat dissipation assembly 300 is arranged by using the gap, so that both sides of the first heat dissipation assembly 300 can fully contact with the second heat conducting part 213, which is conducive to improving the heat dissipation effect of the radiator.

[0066] Furthermore, the cross-sectional shape of the first heat conducting part 211 and the second heat conducting part 213 is square. Compared with the traditional circular cross-sectional heat pipe, the square cross-sectional first heat conducting part 211 and the second heat conducting part 213 can increase the contact area between the first heat conducting part 211 and the heat spreader 100 and the contact area between the second heat conducting part 213 and the first heat dissipation component 300, thereby reducing the thermal resistance and improving the thermal conduction effect.

[0067] Specifically, the thickness of the first heat conducting part 211, the second heat conducting part 213 and the second heat pipe 230 along the X direction is 3mm~4mm, and the width of the first heat conducting part 211, the second heat conducting part 213 and the second heat pipe 230 is 6mm~7mm. By making the width larger than the thickness, the contact area between the first heat conducting part 211 and the heat spreader 100 and the contact area between the second heat conducting part 213 and the first heat dissipation component 300 are not increased, which is beneficial to further improve the heat dissipation efficiency.

[0068] The multiple first heat conducting parts 211 of each group of first heat pipe assemblies 200 are arranged in parallel and in contact with each other along the X direction, and along the X direction, the length of the first heat conducting part 211 gradually shortens or increases from both sides to the middle, so that the second heat conducting part 213 can be arranged in the same plane through the shorter connecting part 212, which can improve the aesthetics of the first heat pipe assembly 200 and reduce the heat conduction distance.

[0069] It is understandable that the heat conduction effect of the heat pipe is reduced after the heat conduction distance is too large. In order to solve this problem, the first heat pipe assembly 200 can also selectively set a second heat pipe 230, and the second heat pipe 230 abuts against the end surface of the second heat conduction part 213 of part of the first heat pipe 210. The second heat pipe 230 and the first heat pipe 210 have the same extension direction, so that the second heat pipe 230 is used to extend the heat conduction length of the two heat conduction parts to avoid the first heat pipe 210 The heat conduction distance is too large and the heat conduction effect of the end of the second heat conduction part 213 is affected by gravity and becomes ineffective. The setting of the second heat pipe 230 is conducive to ensuring the effective heat conduction distance of the first heat pipe assembly 200, improving the heat dissipation rate of the radiator, and enabling the radiator to be suitable for heating parts with a large heat output.

[0070] Specifically, the cross-sections of the first heat conducting part 211 , the second heat conducting part 213 and the second heat pipe 230 are square, so as to increase the contact area and reduce the heat conduction resistance.

[0071] Furthermore, in each group of first heat pipe assemblies 200, the lengths of two adjacent second heat conducting parts 213 are different, so that there is a gap between the two spaced second heat conducting parts 213, and the second heat pipe 230 can abut against the end face of the second heat conducting part 213 located in the middle and be partially inserted in the gap, thereby improving the stability of the second heat pipe 230.

[0072] like Figure 1 to Figure 4 and Figure 6 As shown, optionally, one or more groups of first heat dissipation components 300 can be selectively set in each accommodating space 220, and the setting method can be selected according to the structure of the first heat dissipation component 300, thereby improving the structural flexibility of the radiator to suit users with different needs.

[0073] Alternatively, if Figure 1 to Figure 4 As shown, when multiple groups of first heat dissipation components 300 are arranged in each accommodating space 220, two groups of first heat dissipation components 300 are relatively snap-fitted to form a heat dissipation unit. The two groups of first heat dissipation components 300 snap-fitted can be placed and the snap-fitted positions play a supporting role, which is beneficial to improving the structural stability.

[0074] Multiple heat dissipation units are arranged in each accommodation space 220, and the multiple heat dissipation units are stacked along the Z direction, that is, the accommodation space 220 is filled by assembling and stacking multiple groups of first heat dissipation components 300, which is conducive to reducing the size of each first heat dissipation component 300, reducing the processing difficulty, and reducing the processing cost. At the same time, this structure makes the structure of the radiator more flexible, so that the radiator can selectively set the number of specific first heat dissipation components 300 according to the heat of the heating element, which is conducive to expanding the application range of the radiator.

[0075] like Figure 7 As shown, the first heat dissipation assembly 300 includes a mounting frame 310 and a plurality of fins 320. The fins 320 extend along the Y direction, and the plurality of fins 320 are arranged on the mounting frame 310 in parallel and at intervals along the Z direction, thereby ensuring a heat dissipation effect.

[0076] In another embodiment, if Figure 6 and Figure 7 As shown, a heat dissipation unit is disposed in each accommodating space 220 to facilitate assembly.

[0077] In another embodiment, when multiple groups of first heat dissipation components 300 are arranged in each accommodating space 220, and each group of first heat dissipation components 300 are stacked along the Z direction, the radiator structure is more flexible, so that the radiator can selectively set the number of specific first heat dissipation components 300 according to the heat of the heating element, which is conducive to expanding the application range of the radiator.

[0078] Optionally, the first heat dissipation component 300 is formed by continuous extrusion, which is beneficial to reducing processing costs. Of course, the first heat dissipation component 300 can also be formed by stamping. This molding method is convenient for increasing the thickness of the mounting frame 310, which is beneficial to the structural strength of the first heat dissipation component 300.

[0079] Furthermore, along the X direction, the first heat dissipation assembly 300 is still arranged outside the second heat conducting parts 213 located at the outermost ends of the multiple groups of first heat pipe assemblies 200, so that each side surface of the second heat conducting part 213 can contact the first heat dissipation assembly 300 to improve the heat dissipation efficiency.

[0080] As an alternative, see Figure 1 to Figure 4 and Figure 8 to Figure 10 The radiator can also be selectively provided with a second heat pipe assembly 400. The second heat pipe assembly 400 is divided into two groups. Along the X direction, the two groups of second heat pipe assemblies 400 are relatively arranged on both sides of the first heat pipe assembly 200, thereby increasing the heat conduction structure of the radiator, which is conducive to further improving the heat dissipation effect of the radiator.

[0081] Specifically, Figure 8 to Figure 10 As shown, the second heat pipe assembly 400 includes a plurality of third heat conducting parts 410 and a plurality of third heat pipes 420, and the plurality of third heat pipes 420 are arranged one by one with the plurality of third heat conducting parts 410, and the third heat pipes 420 are configured to extend the heat conduction distance of the third heat conducting parts 410. The second heat pipe assembly 400 structure is provided with a second heat pipe assembly on both sides, so that the radiator conducts heat and dissipates heat through the external second heat pipe assembly 400 and the internal first heat pipe assembly 200, which is beneficial to improve the heat dissipation power of the radiator and can be applied to heating parts with large heat generation. For example, in this embodiment, the second heat pipe assembly 400 includes four third heat conducting parts 410 and four third heat pipes 420.

[0082] Part of the third heat pipe 420 is overlapped with part of the third heat conducting part 410, so that the side surface of the third heat pipe 420 forms a surface-to-surface contact with the side surface of the third heat conducting part 410 for a distance, thereby increasing the heat conduction area between the third heat pipe 420 and the third heat conducting part 410, which is beneficial to improving the heat conduction effect.

[0083] Optionally, the third heat pipe 420 is an L-shaped structure, and the interconnected third heat conducting part 410 and the third heat pipe 420 form a U-shaped structure, so that the third heat pipe 420 can wrap the first heat pipe assembly 200 from both sides of the first heat pipe assembly 200, so that the third heat pipe 420 can be close to the two outermost first heat dissipation assemblies 300, so as to dissipate heat by utilizing the first heat dissipation assembly 300 while conducting heat.

[0084] In order to fix the connection between the third heat conducting part 410 and the third heat pipe 420, a fixing member 440 may be provided at the overlapping position, and the fixing member 440 is simultaneously sleeved on the third heat conducting part 410 and the third heat pipe 420 to improve the stability of the connection between the third heat conducting part 410 and the third heat pipe 420.

[0085] At this time, please continue to see Figure 8 to Figure 10 The third heat pipe 420 includes a fourth heat conducting portion 421 extending along the X direction, and the fourth heat conducting portion 421 is spaced apart from the first heat dissipation component 300. The radiator also includes a second heat dissipation component 500, and the second heat dissipation component 500 is arranged on both sides of the fourth heat conducting portion 421 facing and facing away from the first heat dissipation component 300. The L-shaped third heat pipe 420 can achieve three-time heat conduction and temperature uniformity. The second heat dissipation component 500 dissipates the heat of the fourth heat conducting portion 421 to further improve the heat dissipation efficiency.

[0086] Exemplarily, the structure of the second heat dissipation assembly 500 may be the same as that of the first heat dissipation assembly 300 , and the second heat dissipation assembly 500 includes a mounting frame 310 and fins 320 . The size and quantity of the second heat dissipation assembly 500 may be set accordingly according to the fourth heat conducting portion 421 .

[0087] Along the Y direction, two adjacent fourth heat conducting parts 421 are spaced apart to avoid heat conduction between the two adjacent fourth heat conducting parts 421 , which is beneficial to improving the heat dissipation efficiency of the second heat dissipation assembly 500 for the fourth heat conducting parts 421 .

[0088] Optionally, the heat conduction effect of the heat pipe is reduced when the heat conduction distance is too large. To solve this problem, Fig.10 As shown, the second heat pipe assembly 400 can also selectively be provided with a fourth heat pipe 430, which is provided between the third heat conducting part 410 and the third heat pipe 420, so as to utilize the heat conducting length of the fourth heat pipe 430 to achieve three-fold heat conduction and temperature uniformity, so as to avoid the heat conducting distance of the second heat pipe assembly 400 being too large and causing the heat conducting effect at the end to fail due to the influence of gravity, and the fourth heat pipe 430 is in contact with the L-shaped third heat pipe 420 to avoid failure in the negative direction. The provision of the fourth heat pipe 430 is conducive to ensuring the effective heat conducting distance of the second heat pipe assembly 400, improving the heat dissipation rate of the radiator, and enabling the radiator to be suitable for heating elements with a large heat output.

[0089] Both ends of the fourth heat pipe 430 are overlapped with the third heat conducting part 410 and the third heat pipe 420, respectively, so that a surface-to-surface contact is formed between the side surface of the third heat pipe 420 and the side surface of the fourth heat pipe 430, and between the side surface of the third heat conducting part 410 and the side surface of the fourth heat pipe 430 for a distance, thereby increasing the heat conduction area and facilitating improving the heat conduction effect.

[0090] The third heat conducting part 410 includes an L-shaped abutting tube 411 and a heat transfer tube 412. The abutting tube 411 abuts against the end surface of the heat spreader 100 away from the first heat pipe assembly 200, so that the abutting tube 411 can fully contact the heat spreader 100, and absorb heat by increasing the contact area to improve the overall heat dissipation efficiency of the radiator. The heat transfer tube 412 is extended along the Z direction to conduct heat to the far end.

[0091] Optionally, since the middle position of the U-shaped first heat pipe 210 can only conduct heat and dissipate heat through the second heat conducting parts 213 at both ends, the heat dissipation efficiency in the middle of the multiple first heat pipes 210 of the multiple groups of first heat pipe assemblies 200 is low. In order to solve this problem, along the Y direction, the multiple abutting tubes 411 of the multiple third heat conducting parts 410 are arranged close to the middle, so as to improve the heat conduction and heat dissipation effect in the middle position.

[0092] Specifically, the third heat conducting parts 410 can be arranged in pairs at intervals, which is beneficial to increase the heat absorption area of ​​the third heat conducting parts 410. The two third heat conducting parts 410 in the same group are arranged in contact with each other, so that the third heat conducting parts 410 are mutually heat-conducted to achieve a uniform temperature effect.

[0093] In other embodiments, two adjacent third heat conducting parts 410 are disposed at intervals, which is beneficial to increase the heat absorption area of ​​the third heat conducting parts 410 .

[0094] It is understandable that the heating element is arranged in the middle of the heat spreader 100. In order to improve the heat dissipation efficiency of the radiator, as an optional solution, the radiator also includes a third heat dissipation assembly 600, which is divided into two groups. Along the X direction, the two groups of third heat dissipation assemblies 600 are arranged back to back and close to the two ends of the heat spreader 100, so that the third heat dissipation assembly 600 can absorb heat and dissipate heat from both sides of the heating element, that is, the first heat dissipation assembly 300 and the two third heat dissipation assemblies 600 can form heat dissipation in three directions for the heating element, which is conducive to further improving the heat dissipation rate of the radiator. The structure of the third heat dissipation assembly 600 can be selectively set according to the heat generation of the heating element, thereby improving the structural flexibility and scope of application of the radiator.

[0095] like Figure 11 to Figure 13As shown, the third heat dissipation assembly 600 includes a heat dissipation element 610 and a U-shaped heat pipe 620. The heat dissipation element 610 extends along the Y direction, one side of the U-shaped heat pipe 620 abuts against the heat spreader 100, and the U-shaped heat pipe 620 is sleeved on the heat dissipation element 610, thereby forming a heat absorption and heat dissipation working group.

[0096] Furthermore, two end faces of the heat sink 610 along the Z direction are provided with slots, and a part of the U-shaped heat pipe 620 is inserted into the slots, so that one side of the heat sink 610 abuts against the heat spreader 100. The slots can make the U-shaped heat pipe 620 and the heat sink 610 close to each other, thereby improving the heat dissipation effect. At the same time, solder paste is applied to the gap between the U-shaped heat pipe 620 and the side wall of the slot for welding to ensure the heat conduction efficiency. The slots can also prevent the U-shaped heat pipe 620 from moving.

[0097] Optionally, the U-shaped heat pipe 620 is partially located in the slot and has a square cross-section shape to increase the contact area and reduce the thermal resistance.

[0098] There are multiple U-shaped heat pipes 620, and the multiple U-shaped heat pipes 620 can be arranged in parallel or at an angle. When the multiple U-shaped heat pipes 620 are arranged at an angle, the side away from the heat spreader 100 can be spaced apart to expand the heat dissipation surface.

[0099] The heat sink 610 of the third heat sink assembly 600 may have the same structure as the first heat sink assembly 300, and only needs to be modified according to the size of the third heat sink assembly 600. Of course, the heat sink 610 may also be formed by two first heat sink assemblies 300 being relatively engaged and connected.

[0100] Embodiment 2

[0101] The structure of this embodiment is different from that of the embodiment in that the first heat dissipation component 300 in each solute space is arranged differently.

[0102] like Fig.14 As shown, in this embodiment, only one first heat dissipation assembly 300 is disposed in each accommodating space 220 , and the first heat dissipation assembly 300 can directly fill the accommodating space 220 , thereby improving assembly efficiency.

[0103] Embodiment 3

[0104] The structures of the heat sink 100, the first heat pipe assembly 200, the first heat dissipation assembly 300, the second heat dissipation assembly 500 and the third heat dissipation assembly 600 in this embodiment are basically the same as those in the first embodiment, and are not described in detail here. The difference between this embodiment and the first embodiment lies in the different structure and setting position of the second heat pipe assembly 400.

[0105] like Figure 15 to Figure 17As shown, in this embodiment, the second heat pipe assembly 400 includes a plurality of third heat conducting parts 410 and a plurality of third heat pipes 420, and the plurality of third heat pipes 420 are arranged one by one with the plurality of third heat conducting parts 410, and the third heat pipes 420 are configured to extend the heat conduction distance of the third heat conducting parts 410. The structure of the second heat pipe assembly 400 is conducive to improving the heat dissipation power of the radiator, so that the radiator can be applied to a heating element with a large heat output. Exemplarily, in this embodiment, the second heat pipe assembly 400 includes four third heat conducting parts 410 and four third heat pipes 420.

[0106] Part of the third heat pipe 420 is overlapped with part of the third heat conducting part 410, so that the side surface of the third heat pipe 420 forms a surface-to-surface contact with the side surface of the third heat conducting part 410 for a distance, thereby increasing the heat conduction area between the third heat pipe 420 and the third heat conducting part 410, which is beneficial to improving the heat conduction effect.

[0107] The third heat pipe 420 is coplanar with the second heat conducting parts 213 of the two outermost groups of first heat pipe assemblies 200 along the X direction. At this time, the third heat pipe 420 is the same as the second heat conducting part 213 and can abut against the side wall of the first heat dissipation assembly 300 located in the accommodating space 220 .

[0108] At this time, the third heat pipe 420 is a linear structure extending along the Z direction.

[0109] Optionally, the third heat conducting part 410 includes an L-shaped abutment tube 411 and a heat transfer tube 412. Since the middle position of the U-shaped first heat pipe 210 can only conduct heat and dissipate heat through the second heat conducting parts 213 at both ends, the heat dissipation efficiency in the middle of the multiple first heat pipes 210 of the multiple groups of first heat pipe assemblies 200 is low. In order to solve this problem, the abutment tube 411 is inserted into the side of the accommodating space 220 close to the heat spreader 100 and abuts against the first heat pipe assembly 200, and the heat transfer tube 412 is extended along the Z direction, so that the abutment tube 411 can absorb heat from the middle for heat conduction and heat dissipation, which is convenient for improving the heat conduction and heat dissipation effect in the middle position.
