Technical Field

[0003] The present disclosure relates to the field of server heat dissipation equipment, and in particular to an unshielded heat dissipation module and a server. Background Art

[0004] At present, the configuration of server systems is complex, the manual operation space for component disassembly and assembly is getting smaller and smaller, and the disassembly and assembly of fans on server chassis is cumbersome.

[0059] The core of the present disclosure is to provide an unshielded heat dissipation module and server, which are used to improve the disassembly and assembly efficiency of heat dissipation components and the heat dissipation effect.

[0060] In order to enable those skilled in the art to better understand the present disclosure, the present disclosure is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0061] Please refer to Figures 1 and 14. In this embodiment, the unshielded heat dissipation module includes:

[0062] The heat dissipation component 1 has an air duct for forming a heat dissipation airflow;

[0063] The support base 2 is used to set the heat dissipation component 1. The support base 2 is movably provided with a positioning mechanism. When the heat dissipation component 1 is set on the support base 2, the positioning mechanism can position the heat dissipation component 1 and the support base 2;

[0064] The base 3 is used for being mounted on the chassis, and the base 3 is configured to have an assembly space for the support base 2 to enter;

[0065] The locking mechanism 4 is used to lock the support seat 2 and the base 3. When the support seat 2 and the heat dissipation component 1 move synchronously into the locking position of the assembly space, the locking mechanism 4 is in a locked state, and the support seat 2 and the base 3 are relatively fixed; and in the locked state, the support seat 2, the base 3 and the locking mechanism 4 all avoid the flow direction of the air duct.

[0066] Specifically, the heat sink 1, support base 2, and base 3 are arranged in sequence along a vertical direction. The vertical direction is defined when the heat sink 1 is installed vertically. When the installation direction of the heat sink 1 changes, the arrangement direction of the heat sink 1, support base 2, and base 3 will also change, but the arrangement order remains unchanged. Furthermore, the support base 2 is provided to support the heat sink 1. Furthermore, by providing a positioning mechanism on the support base 2, the positioning mechanism can position the heat sink 1 and the support base 2, ensuring that the positions of the heat sink 1 and the support base 2 are relatively fixed. When the heat sink 1 moves, it can drive the support base 2 to move. When the heat sink 1 drives the support base 2 to move, the movement can be either horizontal or vertical.

[0067] The heat dissipation component 1 and the support seat 2 can enter the assembly space of the base 3 in the vertical direction or the horizontal direction. That is to say, after the heat dissipation component 1 is stably set on the support seat 2, the heat dissipation component 1 and the support seat 2 can enter the assembly space of the base 3 in the vertical direction or in the vertical direction. The specific installation method can be selected according to the space in the chassis. For example, if the horizontal space in the chassis is larger, it is installed in the horizontal direction; if the longitudinal space in the chassis is larger, it is installed in the vertical direction; the heat dissipation component 1 and the support seat 2 and the heat dissipation component can move synchronously toward the direction of the base 3 and enter the assembly space of the base 3. When the support seat 2 and the heat dissipation component move to the locking position of the assembly space at the same time, the position of the support seat 2 and the base 3 is locked by the locking mechanism 4 to keep the support seat 2 and the base 3 relatively fixed; when it is necessary to separate the support seat 2 and the base 3, the support seat 2 and the base 3 can be separated by unlocking the corresponding locking mechanism 4, and then the heat dissipation component 1 and the support seat 2 are separated, so that the heat dissipation component 1 can be disassembled.

[0068] That is to say, the heat dissipation component 1 is positioned relative to the support seat 2 through the positioning mechanism, and the support seat 2 is positioned relative to the base 3 through the locking mechanism 4. During the disassembly and assembly of the heat dissipation component 1, it is only necessary to use the displacement of the heat dissipation component 1 to drive the displacement of the support seat 2, thereby changing the relative position of the support seat 2 and the base 3, and when the support seat 2 and the heat dissipation component 1 are moved to the locking position of the assembly space of the base 3, the locking of the support seat 2 and the base 3 can be achieved only by the action of the locking mechanism 4; in this unshielded heat dissipation module, the locking and unlocking between the support seat 2 and the base 3 are achieved by the locking mechanism 4, and the support seat 2, the base 3 and the locking mechanism 4 are all arranged at the bottom of the heat dissipation component 1, that is, at the end of the heat dissipation component 1 close to the chassis.

[0069] This unshielded heat dissipation module only requires tools to fix the base 3 to the chassis. The disassembly and assembly process of the heat dissipation component 1 does not require the use of tools, and can achieve tool-free quick disassembly and assembly, which not only effectively improves the disassembly and assembly efficiency, but also has a small operating space, which can reduce the requirements for the internal space of the chassis. It is easy to disassemble and assemble, with low labor costs, more convenient system maintenance, high versatility, and improved product competitiveness. It also avoids the use of chassis and rivets in related technologies, which can effectively save costs; and the support base 2, base 3 and locking mechanism 4 can completely avoid the air duct of the heat dissipation component 1, thereby effectively reducing the influence of the support base 2, base 3 and locking mechanism 4 on the heat dissipation effect of the heat dissipation component 1.

[0070] Furthermore, taking the cooling fan as an example, the heat dissipation component 1 has positioning holes 10 at both ends of the air duct of the heat dissipation component 1. Generally, four positioning holes 10 are provided at each end of the air duct of the heat dissipation component 1, which are distributed at the four corners at both ends of the heat dissipation component 1; in the unshielded heat dissipation module, the support seat 2 is positioned with the four positioning holes 10 at both ends of the bottom of the heat dissipation component 1 through the heat dissipation hole pins fixed thereon or the heat dissipation hole pins movably set thereon, and the four positioning holes 10 at the top of the heat dissipation component 1 do not need to be connected. In this way, not only is the shielding of the air duct of the heat dissipation component 1 completely avoided, but the contact area with the heat dissipation component 1 is also small, thereby reducing the wear on the heat dissipation component 1 and extending the service life of the heat dissipation component 1; in addition, since the heat dissipation component 1 is a symmetrical structure, when the positioning holes 10 at the bottom of the heat dissipation component 1 are worn, the heat dissipation component 1 can be flipped over and installed, so that the positioning holes 10 at the top of the heat dissipation component 1 are at the bottom, thereby improving the reliability of the heat dissipation component 1.

[0071] In some embodiments, the air duct is a horizontal air duct, and the support seat 2, base 3 and locking mechanism 4 are all located at the bottom of the heat dissipation component 1. A plurality of limiting walls 20 are provided around the periphery of the support seat 2, and a storage space for the heat dissipation component 1 is formed between each limiting wall 20. The limiting walls 20 extend in a direction away from the base 3 and the top of the limiting walls 20 is lower than the bottom of the air duct. Specifically, the size of the storage space should match the size of the heat dissipation component 1 to pre-position the heat dissipation component 1; the heat dissipation hole pin can be provided on the limiting wall 20, and when installing the heat dissipation component 1, the positioning hole 10 of the heat dissipation component 1 can be aligned with the heat dissipation hole pin; of course, the heat dissipation hole pin can also be moved to cooperate with the positioning hole 10 through other linkage structures. Furthermore, the limiting walls 20 extend in a direction away from the base 3 and the top of the limiting walls 20 is lower than the bottom of the air duct, thereby avoiding any obstruction to the air duct of the heat dissipation component 1. Specifically, a avoidance arc surface can be set at the top of the limiting wall 20, and the shape of the avoidance arc surface is consistent with the bottom shape of the air duct. The heat dissipation hole pins can be set on the limiting wall 20 and located on both sides of the avoidance arc surface, which makes it convenient to set the heat dissipation hole pins while reducing the impact on the air duct.

[0072] In some embodiments, the chassis further includes a plurality of limiting posts 322 pre-installed on the chassis and fasteners for use with the limiting posts 322. The base 3 is provided with an assembly hole 30 for the limiting posts 322 to pass through. The base 3 is detachably connected to the chassis via the limiting posts 322 and the fasteners. The support base 2 is provided with a clearance structure for avoiding the fasteners. Specifically, the limiting posts 322 and the fasteners can also be replaced with rivets, or the limiting posts 322 can be studs and the fasteners can be nuts. Any connection method that can secure the base 3 to the chassis is acceptable. Furthermore, to facilitate the locking position of the support base 2 in the assembly space of the base 3, a clearance structure can be provided on the support base 2 to ensure that the support base 2 can be smoothly assembled and locked with the base 3.

[0073] In some embodiments, please refer to Figures 3, 7 and 9, the support seat 2 is a first support seat 21; the first support seat 21 includes a seat body 211, a snap-fit ​​seat 212 and a mounting buckle 213, and the positioning mechanism is configured as a plurality of first heat dissipation hole pins 214 located on the seat body 211 and the mounting buckle 213; the seat body 211 is installed on the snap-fit ​​seat 212, and the mounting buckle 213 is detachably snapped onto one end of the snap-fit ​​seat 212, and the first heat dissipation hole pins 214 on the seat body 211 and the mounting buckle 213 can be respectively snapped onto both sides of the heat dissipation component 1 along the flow direction. Specifically, the structure of the entire first support seat 21 is formed by assembling the seat body 211, the snap seat 212 and the mounting buckle 213. The first heat dissipation hole pins 214 on the seat body 211 and the mounting buckle 213 are respectively located at the two ends of the air duct of the heat dissipation component 1. During installation, the positioning hole 10 at one end of the heat dissipation component 1 can be first matched and connected with the first heat dissipation hole pin 214 on the seat body 211; then the first heat dissipation hole pin 214 on the mounting port is matched and connected with the positioning hole 10 at the other end of the heat dissipation component 1; the seat body 211 and the snap seat 212 are fixedly connected by screws and other structures, and the mounting buckle 213 is fixed with the help of the snap seat 212, thereby ensuring that the seat body 211, the snap seat 212 and the mounting buckle 213 are fixed to each other while completing the positioning of the heat dissipation component 1; the operation is convenient, and reliable positioning is achieved for both ends of the air duct of the heat dissipation component 1.

[0074] In some embodiments, as shown in FIG9 , the mounting buckle 213 includes a buckle plate 2131 and heat dissipation buckles 2132 located on both sides of the buckle plate 2131. The buckle plate 2131 is provided with a first heat dissipation hole pin 214. The engaging seat 212 is provided with an engaging slot 2121. One end of the heat dissipation buckle 2132 can be engaged with the engaging slot 2121, and the other end extends to the side of the buckle plate 2131 away from the engaging seat 212 to form a pressing handle 2133. Specifically, the buckle plate 2131 functions similarly to the limiting wall 20. The buckle plate 2131 and the limiting wall 20 on the seat body 211 jointly form a receiving space. The heat dissipation buckles 2132 are interactively arranged on both sides of the buckle plate 2131. One side of the heat dissipation buckle 2132 serves as a pressing handle 2133, and the other side can be engaged with the engaging slot 2121 on the engaging seat 212. It should be noted that a retaining spring should be provided at the connection between the buckle plate 2131 and the heat dissipation buckle 2132, so that the heat dissipation buckle 2132 has a certain pre-tightening force. When the heat dissipation buckle 2132 moves toward the snap seat 212, the snap seat 212 will stretch the two heat dissipation buckles 2132 apart until the heat dissipation buckle 2132 is engaged with the snap slot 2121; when it is necessary to remove the mounting buckle 213, press the corresponding pressing handle 2133 on the side of the buckle plate 2131 away from the snap seat 212, so that the heat dissipation buckle 2132 is separated from the snap slot 2121, and the mounting buckle 213 can be separated from the snap seat 212.

[0075] In some embodiments, referring to Figures 3 and 8 , a foolproof slot 2111 is provided at one end of the base 211 facing away from the positioning mechanism, and a foolproof boss 2122 is provided on the engaging seat 212 to cooperate with the foolproof slot 2111. Fastening holes are provided at corresponding positions on the base 211 and the engaging seat 212. Specifically, by providing the foolproof slot 2111 on the base 211 and the foolproof boss 2122 on the engaging seat 212, the fastening holes on the base 211 and the engaging seat 212 can be quickly positioned during assembly of the base 211 and the engaging seat 212, thereby improving assembly efficiency.

[0076] In some embodiments, please refer to Figure 2, the base 3 is a first base 313, and at least two guide bars 311 are provided on the first base 313. The assembly space is located between adjacent guide bars 311, and the snap seat 212 can slide into the assembly space. A limiting tooth 312 is provided on the opposite side of each guide bar 311; elastic arms 2123 are provided on both sides of the end of the snap seat 212, and tooth elastic points 2124 that cooperate with the limiting teeth 312 are provided on the elastic arms 2123; the locking mechanism 4 can lock the tooth elastic point 2124 and the limiting tooth 312 after the snap seat 212 moves to the locking position. Specifically, the position of the elastic arm 2123 is limited by the locking mechanism 4 to prevent the elastic arm 2123 from elastic deformation, thereby preventing the snap seat 212 from moving.

[0077] In some embodiments, a sliding groove is further provided on the bottom of the limiting tooth 312 on the first base 313, and avoidance slides 2129 are provided on both sides of the locking seat 212. The avoidance slides 2129 can slide into the sliding groove of the first base 313. Under the restriction of the avoidance slides 2129 and the sliding groove, the locking seat 212 can only slide along the extension direction of the limiting tooth 312, and cannot move in the vertical direction, thereby ensuring the stability of the locking seat 212.

[0078] In some embodiments, the locking mechanism 4 is a locking piece 41, one end of which is provided with a locking cantilever, comprising a first locking cantilever 411 and a second locking cantilever 412. The first locking cantilever 411 and the second locking cantilever 412 are located on both sides of one end of the locking piece 41, and a locking movable shaft 413 is provided on the opposite side of the first locking cantilever 411 and the second locking cantilever 412. Specifically, the first locking cantilever 411 and the second locking cantilever 412 are located at the same end of the locking piece 41, and the locking movable shaft 413 of the first locking cantilever 411 and the locking movable shaft 413 of the second locking cantilever 412 are close to each other to form a rotating structure.

[0079] One end of the engaging seat 212 is provided with a movable shaft groove, and the movable shaft groove includes a first movable shaft groove 2125 and a second movable shaft groove 2126. The first movable shaft groove 2125 and the second movable shaft groove 2126 are distributed on both sides of the same end of the engaging seat 212. The extension directions of the first movable shaft groove 2125 and the second movable shaft groove 2126 are parallel to the sliding direction of the engaging seat 212. The first movable shaft groove 2125 and the second movable shaft groove 2126 are both provided with a starting end and a terminal end. As shown in Figure 5, the starting ends of the first movable shaft groove 2125 and the second movable shaft groove 2126 are both provided with a notch 2127, and the notch 2127 extends from the surface of the engaging seat 212 to the first movable shaft groove 2125 or the second movable shaft groove At the beginning of the movable shaft groove 2126, the locking movable shaft 413 slides into the first movable shaft groove 2125 or the second movable shaft groove 2126 through the notch 2127. The terminal positions of the first movable shaft groove 2125 and the second movable shaft groove 2126 define the extreme position when the locking piece 41 is pulled out, that is, the locking position of the locking piece 41. Specifically, a constriction is provided on the notch 2127. The size of the constriction is smaller than the size of the locking movable shaft 413 to limit the locking movable shaft 413 and prevent the locking movable shaft 413 from falling out of the movable shaft groove. When installing the locking movable shaft 413, as shown in FIG. 4 , the locking movable shaft 413 is pressed into the notch 2127 of the movable shaft groove.

[0080] When the locking piece 41 is in the locked position, the two ends of the locking limit groove 414 respectively abut against the locking points 2128 on the two elastic arms 2123, and the locking piece 41 no longer moves. At the same time, the elastic deformation ability of the two elastic arms 2123 is eliminated, thereby limiting the position of the elastic arms 2123, thereby achieving the position limitation of the engaging seat 212 and the first base 313, and completing the locking; further, the locking limit groove 414 can be a through groove, or it can be a structure with two grooves at both ends of the bar rod, which can achieve the limitation of the elastic arms 2123.

[0081] The locking movable shaft 413 can slide in the corresponding first movable shaft groove 2125 or the second movable shaft groove 2126 to make the locking piece 41 located in the locking position or the unlocking position; when the locking piece 41 moves to the locking position, the engaging spring point 2128 engages with the locking limit groove 414, and when the locking piece 41 moves to the unlocking position, the engaging spring point 2128 separates from the locking limit groove 414, completing the abutment or release of the locking piece 41 on the engaging spring point 2128, thereby completing the locking or unlocking of the locking piece 41 on the engaging seat 212 and the first base 313.

[0082] In some embodiments, as shown in Figures 3, 8, and 10, the locking piece 41 is further provided with a plurality of locking anti-slip grooves 415, and the side of the base 211 facing away from the mounting buckle 213 is provided with a plurality of limiting protrusions 2112. When the locking piece 41 is in the unlocked position, the locking anti-slip grooves 415 are engaged with the limiting protrusions 2112 in a one-to-one correspondence. Specifically, the positions of the locking anti-slip grooves 415 and the limiting protrusions 2112 can be interchanged. For example, the locking piece 41 is further provided with a plurality of limiting protrusions 2112, and the side of the base 211 facing away from the mounting buckle 213 is provided with a plurality of locking anti-slip grooves 415. The above arrangement is to ensure that when the first support seat 21 is separated from the first base 313, the locking piece 41 can move along with the base 211 in the first support seat 21, thereby preventing the locking piece 41 from falling out and affecting the movement of the first support seat 21.

[0083] In some embodiments, as shown in FIG3 , a locking grip portion 416 is further provided at one end of the locking piece 41 away from the first locking cantilever 411 and the second locking cantilever 412 . The locking grip portion 416 is U-shaped and is arranged around the edge of the locking piece 41 , which not only facilitates gripping but also increases the strength of the locking piece 41 .

[0084] Specifically, in the first embodiment, as shown in Figures 11, 12 and 13, when the heat dissipation component 1 and the first support seat 21 need to be assembled, first install the first base 313 on the chassis with a pull nail, then align the locking movable shaft 413 of the locking piece 41 with the movable shaft groove of the snap seat 212, and assemble it into the inside of the movable shaft groove; align the anti-foolproof groove card slot on the seat body 211 of the first support seat 21 with the anti-foolproof boss 2122 of the snap seat 212 and lock the screw; align the positioning hole 10 at one end of the heat dissipation component 1 with the first heat dissipation hole pin 214 on the seat body 211, and place the heat dissipation component 1 into the accommodating space of the seat body 211; align the first heat dissipation hole pin 214 on the mounting buckle 213 of the first support seat 21 with the positioning hole 10 at the other end of the heat dissipation component 1, and align the heat dissipation buckle 2132 on the mounting buckle 213 with the snap seat When the fan module is assembled with the first base 313, the fan module is assembled into the space of the first base 313 and inserted along the extending direction of the limiting tooth 312 of the guide bar 311. After the elastic arm 2123 of the engaging seat 212 is pushed to the bottom along the guide bar 311, the locking piece 41 is pulled open so that its locking limiting groove 414 is engaged with the locking elastic point 2128, ensuring that the tooth elastic point 2124 is engaged with the limiting tooth 312, and the assembly is completed. When the fan module needs to be disassembled from the first base 313, the locking piece 41 is pushed toward the direction close to the base body 211 to reset the locking piece 41 so that its locking anti-detachment groove 415 is engaged with the limiting protrusion 2112. Then, the locking limiting groove 414 of the locking piece 41 is separated from the locking elastic point 2128, so that the elastic arm 2123 recovers its elastic deformation ability, and the fan module can be pulled out.

[0085] In some embodiments, as shown in Figure 15, the support seat 2 is a second support seat 22, and the base 3 is a second base 32; at least two engaging cantilevers 221 are provided on the second support seat 22, and each engaging cantilever 221 is located at least at both ends of the second support seat 22, so as to be locked with the second base 32, and at least two pressing buckles 42 are provided on the second base 32 to constitute a locking mechanism 4, and each pressing buckle 42 is located at least at both ends of the second base 32, and the positions of the pressing buckles 42 and the engaging cantilever 221 correspond one to one; when the second support seat 22 moves to the locking position of the assembly space, the pressing buckle 42 is locked with the engaging cantilever 221. When unlocking is required, the corresponding pressing buckle 42 is pressed in the vertical direction to separate the pressing buckle 42 from the engaging cantilever 221.

[0086] In some embodiments, please refer to Figure 16, a locking surface 222 is provided on the side of the locking cantilever 221 close to the base 3, and the locking surface 222 is locked with the press buckle 42. Correspondingly, a locking surface 222 should also be provided on the press buckle 42. The locking surfaces 222 of the locking cantilever 221 and the press buckle 42 are both flat to ensure the locking effect; a force guide surface 223 is provided on the side of the locking cantilever 221 close to the base 3; when the second support seat 22 moves to the locking position of the assembly space, the force guide surface 223 abuts against the press buckle 42 to push the press buckle 42 to undergo elastic deformation, until the press buckle 42 contacts and locks with the locking surface 222. Specifically, the push buckle 42 includes an arc-shaped deformable arm and a push-locking portion. The push-locking portion is located at the top of the arc-shaped deformable arm. When the second support seat 22 moves toward the second base 32, the force-bearing guide surface 223 of the push buckle 42 contacts the push-locking portion, pushing the two arc-shaped deformable arms apart until the engaging surface 222 of the push buckle 42 contacts the engaging surface 222 of the engaging cantilever 221. The arc-shaped deformable arm is reset, completing the locking of the push buckle 42 and the engaging cantilever 221. Specifically, the end of the arc-shaped deformable arm is further provided with a concave and convex portion to facilitate pressing the arc-shaped deformable arm when unlocking, thereby improving efficiency.

[0087] In some embodiments, as shown in Figure 17, the second base 32 is provided with an assembly hole 30 for connecting with the chassis, which can be connected by rivets or screws. The second support seat 22 is provided with an avoidance hole at a position corresponding to the assembly hole 30 to form an avoidance structure. The size of the avoidance hole is larger than the size of the assembly hole 30 to avoid the rivets or screws.

[0088] In some embodiments, please refer to Figure 18, which also includes a shaft positioning assembly 5, and the positioning mechanism is configured as a second heat dissipation hole pin 513 located on the shaft positioning assembly 5. The shaft positioning assembly 5 is connected between the second support seat 22 and the second base 32, and when the second support seat 22 and the second base 32 are locked, the shaft positioning assembly 5 can be deformed to allow the second heat dissipation hole pin 513 to be engaged with the heat dissipation component 1.

[0089] By arranging the second heat dissipation hole pin 513 on the shaft positioning assembly 5, the deformation of the shaft positioning assembly 5 is utilized to realize the positioning and snap connection between the second heat dissipation hole pin 513 and the heat dissipation component 1; with the above arrangement, the shaft positioning assembly 5 is deformed during the movement of the support seat 2 toward the base 3, so the positioning and snap connection between the second heat dissipation hole pin 513 and the heat dissipation component 1 can be completed while the support seat 2 and the base 3 are locked. This method can realize the synchronous positioning and installation of the heat dissipation component 1, significantly improve the disassembly and assembly efficiency, and facilitate the operation. It only requires the heat dissipation component 1 to move in the vertical direction, effectively reducing the demand for assembly space.

[0090] In some embodiments, the shaft positioning assembly 5 includes a first rotating member 51, the first rotating member 51 includes a first bent edge 511 and a second bent edge 512, the first bent edge 511 is perpendicular to the second bent edge 512, and the second heat dissipation hole pin 513 is arranged on the second bent edge 512; in the initial state, the first bent edge 511 is vertically set and the second bent edge 512 is horizontally set. When the second support seat 22 moves toward the assembly space locking position of the second base 32, the first rotating member 51 rotates to the first bent edge 511 horizontally set and the second bent edge 512 vertically set, so that the second heat dissipation hole pin 513 located on the second bent edge 512 is engaged with the positioning hole 10 of the heat dissipation component 1.

[0091] In some embodiments, as shown in FIG18 and FIG20 , the shaft positioning assembly 5 further includes a second rotating member 52 and a third rotating member 53. The second rotating member 52 has two sides hingedly connected to the first rotating member 51 and the third rotating member 53, respectively. The end of the first rotating member 51 facing away from the second rotating member 52 is hingedly connected to the second support seat 22, and the end of the third rotating member 53 facing away from the second rotating member 52 is hingedly connected to the second base 32.

[0092] When the second support base 22 moves toward the assembly space locking position of the second base 32, the first rotating member 51, the second rotating member 52 and the third rotating member 53 are relatively bent so that the second support base 22 fits on the second base 32;

[0093] When the pressing buckle 42 is locked with the engaging cantilever 221, the second bent edge 512 of the first rotating part 51 is close to the heat dissipation component 1, and the second heat dissipation hole pin 513 is engaged with the positioning hole 10 of the heat dissipation component 1; when the pressing buckle 42 is unlocked with the engaging cantilever 221, the second bent edge 512 of the first rotating part 51 is away from the heat dissipation component 1, and the second heat dissipation hole pin 513 is separated from the positioning hole 10 of the heat dissipation component 1.

[0094] The second support seat 22 is provided with buckle grooves on both sides of the engaging cantilever 221, and the second base 32 is provided with buckle grooves on both sides of the pressing buckle 42; the first bent edge 511 of the first rotating member 51 is provided with a rotating shaft pin on both sides, and the second rotating member 52 is provided with a buckle groove on both sides, the rotating shaft pin on the first bent edge 511 close to the second bent edge 512 is hinged to the buckle groove of the second support seat 22, and the rotating shaft pin on the first bent edge 511 away from the second bent edge 512 is hinged to the buckle groove of the second rotating member 52; the third rotating member 53 is provided with a rotating shaft pin on both sides, and the rotating shaft pin of the third rotating member 53 is hinged to the buckle groove of the second rotating member 52 and the second base 32 respectively; and after the second support seat 22 and the second base 32 are assembled, and are in the initial state, the first bent edge 51 of the first rotating member 51 is provided with a rotating shaft pin 511, the second rotating member 52 and the third rotating member 53 are all in a vertical state and are arranged in sequence along the vertical direction. The first bent edge 511 and the side of the third rotating member 53 close to each other are both set as arcuate surfaces, and the arcuate surfaces of the two are arranged in a close relationship to ensure stability; after the second support seat 22 and the second base 32 are locked, the first bent edge 511 of the first rotating member 51 and the third rotating member 53 are both in a horizontal state and in a close relationship. At this time, the second supporting seat 22 is also in a close relationship with the second base 32. Since the second bent edge 512 of the first rotating member 51 is perpendicular to the first bent edge 511, the second bent edge 512 of the first rotating member 51 is in a vertical direction at this time, so that the second heat dissipation hole pin 513 on the second bent edge 512 can just be stuck in the positioning hole 10 at the bottom of the heat dissipation component 1;

[0095] By driving the second rotating member 52 and the third rotating member 53, the first bent edge 511 and the second bent edge 512 of the first rotating member 51 are driven to swing, so that the second support seat 22 and the second base 32 are locked, and the heat dissipation component 1 is positioned and clamped by the second heat dissipation hole pin 513 on the second bent edge 512; the heat dissipation component 1 can be disassembled and assembled in one step, and the disassembly and assembly efficiency is significantly improved.

[0096] In some embodiments, a plurality of positioning portions are provided at the bottom of the heat dissipation component 1, and the number of the rotating shaft positioning assemblies 5 is at least four groups. At least two groups of rotating shaft positioning assemblies 5 are provided at each end of the second support seat 22 and the second base 32, and at least one group of rotating shaft positioning assemblies 5 are provided on both sides of the engaging cantilever 221 located on the second support seat 22; one rotating shaft positioning assembly 5 corresponds to a positioning portion of the heat dissipation component 1, and the positioning portion is a positioning hole 10; specifically, by setting at least four groups of rotating shaft positioning assemblies 5, and at least one group of rotating shaft positioning assemblies 5 are provided on both sides of the engaging cantilever 221, on the one hand, a symmetrical structure is formed to ensure the stability of the entire module, and on the other hand, all four corners of the bottom of the heat dissipation component 1 can be positioned to ensure the stability of the heat dissipation component 1.

[0097] In some embodiments, please refer to Figure 19, which also includes an elastic component 321. The elastic component 321 is located between the locking cantilever 221 and the pressing buckle 42. When the second support seat 22 moves toward the assembly space of the second base 32, the locking cantilever 221 squeezes the elastic component 321 until the locking cantilever 221 and the pressing buckle 42 are locked; when the locking cantilever 221 and the pressing buckle 42 are unlocked, the elastic component 321 is reset to support the second support seat 22; through the setting of the elastic component 321, when the second support seat 22 moves toward the second base 32, the elastic component 321 can be squeezed, and the elastic component 321 produces elastic deformation. When the second support seat 22 and the second base 32 are unlocked, the elastic component 321 is reset to lift the second support seat 22, thereby facilitating the disassembly of the heat dissipation component 1.

[0098] In some embodiments, it also includes at least two limiting columns 322 pre-installed on the chassis, and the engaging cantilever 221 and the pressing buckle 42 are both provided with limiting holes for the limiting columns 322 to pass through. Specifically, the engaging cantilever 221 is provided with a cantilever limiting hole, and the pressing buckle 42 is provided with a buckle limiting hole 323. The limiting column 322 passes through the buckle limiting hole 323 and the cantilever limiting hole in sequence. The elastic component 321 is sleeved on the limiting column 322, and an assembly space is formed between the limiting columns 322 on the second base 32. When the second support seat 22 moves toward the assembly space of the second base 32, the elastic component 321 can be compressed, and the limiting column 322 can play a guiding role to ensure that the second support seat 22 smoothly enters the assembly space locking position of the second base 32.

[0099] In some embodiments, a step is provided on one side of the limiting hole of the engaging cantilever 221 close to the elastic component 321 to limit the elastic component 321. The elastic component 321 can be a spring. By providing a step on the limiting hole of the engaging cantilever 221, the engaging cantilever 221 can be conveniently pressed against the elastic component 321.

[0100] Specifically, in the second embodiment, as shown in Figures 21 and 22, when the second support seat 22 and the second base 32 need to be assembled, first, the second base 32 is placed on the screw of the chassis, and after the screw is locked, the elastic component 321 is placed on the limiting column 322 of the chassis, and the limiting column 322 can be a pin; then the second support seat 22 is placed in the limiting column 322 of the chassis and is lifted up by the elastic component 321; the second rotating member 52 is used to buckle the first rotating member 51 and the third rotating member 53 to obtain the shaft positioning assembly 5, and then the shaft positioning assembly 5 is buckled into the second support seat 22 and the second base 32 at the same time; the heat dissipation component 1 is placed along the limiting wall 20 of the second support seat 22 After insertion, apply downward force to compress the elastic component 321 and rotate the shaft positioning assembly 5 until the second support seat 22 pushes open the pressing buckle 42 of the second base 32, and the locking surface 222 of the pressing buckle 42 is engaged with the locking surface 222 of the locking cantilever 221, and at the same time, the second heat dissipation hole pin 513 on the shaft positioning assembly 5 is locked into the positioning hole 10 of the heat dissipation component 1, and the assembly is completed; when the heat dissipation component 1 needs to be disassembled, press the unlocking pressing area of ​​the pressing buckle 42 on the second base 32 to disengage the locking surface 222 of the locking cantilever 221 of the second support seat 22 from the pressing buckle 42, and after the elastic component 321 applies force to push up the second support seat 22, the heat dissipation component 1 can be taken out.
