[0034] In this application, since the first end of the first fixing mechanism is connected to the liquid cooling mechanism and the second end can move relative to the first end, the movement of the second fixing mechanism connected to it can be driven by the first fixing mechanism, so as to be able to send the second fixing mechanism to the installation area positions corresponding to at least two components to be cooled, so that the second fixing mechanism can be adaptively adjusted according to the positions of the installation areas corresponding to components to be cooled with different sizes; in addition, when the second fixing mechanism is moved into the installation area, the edge of the second fixing mechanism can move relative to the fixing part where the second fixing mechanism is connected to the first fixing mechanism, so that the edge of the second fixing mechanism can be clamped in the installation area to achieve locking, ensuring the reliable installation of the second fixing mechanism relative to the installation area, that is, ensuring the reliable installation of the liquid cooling and heat dissipation mechanism relative to the component to be cooled; therefore, when the component to be cooled is a server component, this application can solve the technical problem that the liquid cooling and heat dissipation device can only correspond to a server component of one size, and achieve that the liquid cooling and heat dissipation device can be adaptively adjusted according to the positions of the installation areas corresponding to server components of different sizes, and can be reliably installed with the installation area after adjustment, so that the technical effects of improving applicability and flexibility can be achieved.

[0048] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0049] The liquid cooling heat dissipation device provided by the present application is used for dissipating heat from the heat dissipation target 5, where the heat dissipation target 5 can specifically be server components such as a motherboard, a board card, and an electronic device that generate heat during operation, or other types of heating devices that require timely and effective heat dissipation to ensure the service life of the components.

[0050] Among them, the liquid cooling heat dissipation device specifically includes a liquid cooling mechanism 4, a first fixing mechanism 2, and a second fixing mechanism 3, which can stably fix the liquid cooling heat dissipation device when encountering heat dissipation components 5 of different sizes. Please refer to Figure 1 、 Figure 2 。

[0051] The liquid cooling mechanism 4 is a mechanism that can provide coolant to dissipate heat from the heat dissipation component 5. Specifically, it contacts the heat dissipation component 5 through the liquid cooling mechanism 4, so that the heat generated by the heat dissipation component 5 can be taken away by the liquid cooling mechanism 4.

[0052] One end of the first fixing mechanism 2 is connected to the liquid cooling mechanism 4, and the second end of the first fixing mechanism 2 can move relative to the first end of the first fixing mechanism 2.

[0053] The second fixing mechanism 3 has a fixing part, and the fixing part is connected to the second end of the first fixing mechanism 2. The second end of the first fixing mechanism 2 can move to drive the second fixing mechanism 3 to move, so that the second fixing mechanism 3 moves until it reaches the position of the installation area 51 corresponding to the heat dissipation component 5. Due to the movement of the first fixing mechanism 2, the second fixing mechanism 3 can move correspondingly according to the position of the installation area 51 of the heat dissipation component 5 of different sizes, so that the liquid cooling heat dissipation device can be applicable to heat dissipation components 5 of different sizes and improve the applicability.

[0054] When the heat dissipation component 5 is a server component, the second fixing mechanism 3 can move according to the position of the installation area 51 of server components of different sizes, so that the liquid cooling heat dissipation device can be applicable to server components of different sizes and improve the applicability and flexibility.

[0055] Specifically, if the server component is a motherboard, the corresponding motherboard has different sizes, resulting in different positions of the installation area 51 on the motherboard. Therefore, the movement of the first fixing mechanism 2 is required to enable the second fixing mechanism 3 to move adaptively according to different positions of the installation area 51, so as to effectively fix the liquid cooling mechanism 4 on different server components and improve the applicability.

[0056] When the second fixing mechanism 3 moves into the installation area 51, the edge of the second fixing mechanism 3 can move relative to the fixing part, so that the second fixing mechanism 3 can be clamped in the installation area 51 to achieve locking. The locking here means that after the second fixing mechanism 3 reaches the position of the installation area 51, it still needs to be locked in the installation area 51 to ensure the reliable installation of the liquid cooling mechanism 4 relative to the heat dissipation component 5 and ensure the reliable operation effect of the liquid cooling mechanism 4.

[0057] The specific fixing part refers to the part where the second fixing mechanism 3 is connected to the first fixing mechanism 2. The edge of the second fixing mechanism 3 can move circumferentially relative to this position, so that the edge of the second fixing mechanism 3 can extend or retract a certain distance, so that the second fixing mechanism 3 can be adjusted according to the installation area 51 of different sizes, and ensure that the second fixing mechanism 3 can be reliably locked in the installation area 51.

[0058] In one embodiment, in order to ensure the reliable locking of the second fixing mechanism 3 and the installation area 51, a engaging part capable of engaging at least part of the circumferential position of the second fixing mechanism 3 can be provided in the installation area 51. When the second fixing mechanism 3 moves, it can engage with the engaging part of the installation area 51, and the reliable locking can be ensured through the engaging relationship.

[0059] In another embodiment, in order to ensure the reliable locking of the second fixing mechanism 3 and the installation area 51, an anti-slip part capable of increasing the friction force can be provided at least part of the edge of the second fixing mechanism 3. The reliable locking effect can also be ensured through the contact between the anti-slip part and the installation area 51.

[0060] In this embodiment, it should be noted that the movement of the edge of the second fixing mechanism 3 means that the second fixing mechanism 3 can move relative to the fixing part towards the inner wall of the installation area 51, so as to achieve the locking effect by fitting or engaging with the inner wall of the installation area 51.

[0061] For the specific form of the installation area 51, it can be a circular hole, a square hole or a hole of other shapes on the heat dissipation part 5 to be dissipated, or a circular groove, a square groove or a groove of other shapes, and no excessive restrictions are made.

[0062] In this embodiment, when the heat dissipation part 5 is a server component, the setting of the first fixing mechanism 2 can make the second fixing mechanism 3 reach the position of the installation area 51 corresponding to the server component of any size. Through the movement of the edge of the second fixing mechanism 3 relative to the fixing part, the second fixing mechanism 3 can be reliably locked in the installation area 51, which can be applicable to server components of various sizes, and can ensure the reliable installation of the liquid cooling mechanism 4 relative to the server component, with flexibility and reliability.

[0063] In this embodiment, the movement of the first fixing mechanism 2 and the movement of the edge of the second fixing mechanism 3 can be realized by means of components such as motors, cylinders, electric cylinders, and oil cylinders.

[0064] For example, the movement of the first fixing mechanism 2 relies on a motor and a rack and pinion structure; the rotation of the motor drives the pinion to rotate, so as to convert the force into the movement of the rack. The second end of the first fixing mechanism 2 is connected to the rack, that is, the rotation of the motor can drive the second end of the first fixing mechanism 2 to move relative to the first end of the first fixing mechanism 2, so as to drive the second fixing mechanism 3 to move until it reaches the position of the installation area 51 corresponding to the server component.

[0065] In this embodiment, the number of the second fixing mechanisms 3 is determined according to the number of the installation areas 51 corresponding to the actual server components. If multiple second fixing mechanisms 3 are provided, the multiple second fixing mechanisms 3 can move synchronously with the movement of the first fixing mechanism 2 to improve the adjustment efficiency.

[0066] In one implementation manner, when the second fixing mechanism 3 reaches the position corresponding to the installation area 51, it may refer to the second fixing mechanism 3 reaching the height position of the installation area 51. If it is necessary to send the second fixing mechanism 3 into the installation area 51, the server component or the second fixing mechanism 3 can be moved. Since this movement amplitude is small, it can be adjusted manually; after the second fixing mechanism 3 enters the installation area 51, it can be locked in the installation area 51 by the circumferential movement of the second fixing mechanism 3.

[0067] In another implementation manner, when the second fixing mechanism 3 reaches the position corresponding to the installation area 51, it may refer to the second fixing mechanism 3 reaching inside the installation area 51. At this time, it can be directly locked in the installation area 51 by the circumferential movement of the second fixing mechanism 3.

[0068] Based on the above embodiments, please refer to Figure 2 、 Figure 4 , a plurality of second fixing mechanisms 3 are circumferentially connected to the first fixing mechanism 2, and the movement of the first fixing mechanism 2 can drive the plurality of second fixing mechanisms 3 to reach the positions of a plurality of corresponding installation areas 51 at the same time.

[0069] Such as Figure 2 As shown, a plurality of second fixing mechanisms 3 are connected to the circumference of the first fixing mechanism 2, corresponding to the case where there are a plurality of installation areas 51 for the heat dissipation part 5 to be provided. If there are four installation areas 51, there are also four corresponding second fixing mechanisms 3. The movement of the first fixing mechanism 2 drives the four second fixing structures to move so as to reach the positions of the corresponding installation areas 51 respectively.

[0070] In one embodiment, the first fixing mechanism 2 is a plurality of electric cylinders, and each electric cylinder can drive the movement of a second fixing mechanism 3. When the plurality of electric cylinders are started synchronously, the corresponding plurality of second fixing mechanisms 3 can move synchronously until they reach the positions of the corresponding installation areas 51. In this case, the distances of the second fixing mechanisms 3 relative to the corresponding installation areas 51 are equal. Therefore, by starting the electric cylinders of the same model simultaneously, the plurality of second fixing mechanisms 3 can be accurately and effectively sent to the positions of the corresponding installation areas 51.

[0071] In one embodiment, the first fixing mechanism 2 is a motor and a driven component. The motor drives the driven component to convert the rotational force into a moving force, and can operate on each second fixing mechanism 3 respectively to achieve the synchronous movement of the plurality of second fixing mechanisms 3.

[0072] In this embodiment, the movement of the first fixing mechanism 2 drives the plurality of second fixing mechanisms 3 simultaneously, so as to improve the adjustment efficiency and ensure convenience and rapidness when adjusting the heat dissipation components 5 of different sizes.

[0073] Based on any of the above embodiments, please refer to Figure 3 , the first fixing mechanism 2 includes a slide rail 202, a sliding plate 201, and a driving component.

[0074] The slide rail 202 is fixed to the liquid cooling mechanism 4 and is provided with a plurality of sliding parts. As Figure 3 shown, the slide rail 202 can be a cross-shaped slide rail 202. The liquid cooling mechanism 4 is fixed at the center position of the cross-shaped slide rail 202, and the edges of the cross-shaped slide rail 202 correspond to the plurality of sliding parts. Of course, it is not limited to this cross-shaped slide rail 202, and it can also be a star-shaped or other forms with a cross structure.

[0075] The sliding plate 201 is slidably connected to the corresponding sliding part, and the driving end of the driving component is connected to the plurality of sliding parts to drive the movement of the second fixing mechanisms 3 respectively connected to the plurality of sliding parts.

[0076] The driving component can realize the movement of the second fixing mechanisms 3 connected to the plurality of sliding plates 201 by the sliding of the plurality of sliding plates 201 relative to the sliding parts, that is, it can realize the adaptive sliding adjustment of the plurality of second fixing mechanisms 3 according to the positions of the installation areas 51. Combined with the fact that the edges of the second fixing mechanisms 3 can move relative to the fixing parts, the use requirements of reliably connecting the liquid cooling mechanism 4 to the heat dissipation components 5 of different sizes can be met, and the applicability is improved.

[0077] In this embodiment, the sliding direction of each sliding plate 201 corresponds to the direction of its sliding part. The driving component can synchronously drive multiple sliding plates 201 to move along the corresponding sliding parts, so as to simultaneously adjust the positions of multiple second fixing mechanisms 3 and improve the adjustment efficiency.

[0078] In this embodiment, the driving component can be multiple electric cylinders or a combination of a motor and a power conversion element, which can achieve the effect of driving the sliding plate 201 to translate.

[0079] In this embodiment, the slidable range of the sliding plate 201 corresponds to the moving range of the second fixing mechanism 3, that is, it corresponds to the heat dissipation parts 5 of multiple sizes. When the heat dissipation part 5 is a server component, the slidable range of the sliding plate 201 also corresponds to server components of different sizes.

[0080] Based on any of the above embodiments, please refer to Figure 3 、 Figure 4 , the driving component includes: a driving member 206; an arc-shaped rod 205. Multiple arc-shaped rods 205 are distributed on the outer periphery of the hinge plate 204 and are all arranged towards the center of the hinge plate 204. One end of the arc-shaped rod 205 is hinged to the edge of the hinge plate 204, and the other end of the arc-shaped rod 205 is hinged to the sliding plate 201. The driving member 206 can drive the hinge plate 204 to rotate, so as to drive the sliding plate 201 to move through the arc-shaped rod 205.

[0081] The driving member 206 can specifically be a motor or a rotary component such as a handwheel, and is specifically set according to the actual installation situation and space situation.

[0082] Taking an implementation manner as an example, the driving member 206 is a motor, and the motor can meet forward and reverse rotation to achieve the reciprocating movement of the second fixing mechanism 3 relative to the sliding part. Through the setting of the motor, it can improve the convenience of the adjustment operation and reduce the installation limitation for the situation of difficult manual adjustment caused by the narrow internal space and special-shaped structure of the server.

[0083] Specifically, the driving member 206 can be fixed on the fixing frame 207, and the fixing frame 207 is fixed to the liquid cooling mechanism 4. The specific fixing method is detachable connection, and the fixing frame 207 can provide a place for installing and fixing the driving member 206.

[0084] The output shaft 203 of the driving member 206 is connected to the hinge plate 204. By rotating the driving member 206, the hinge plate 204 can be driven to rotate. With the linkage of the arc-shaped rod 205, the sliding plate 201 can be driven to slide on the sliding part, so as to achieve the effect of simultaneously adjusting the positions of multiple second fixing mechanisms 3.

[0085] In this embodiment, by providing a plurality of arc-shaped rods 205 arranged around the outer periphery of the hinge plate 204, the force of the rotation of the hinge plate 204 can be transmitted to the sliding plate 201 through the arc-shaped rods 205 to drive the sliding of the sliding plate 201.

[0086] In this embodiment, among two adjacent arc-shaped rods 205, the end portion of one hinged to the edge of the hinge plate 204 is located within the arc region of the other, so that the plurality of arc-shaped rods 205 can be staggered. During operation, the plurality of arc-shaped rods 205 do not interfere with each other and can move synchronously with the rotation of the hinge plate 204. The simultaneous adjustment of a plurality of sliding plates 201 relative to the corresponding plurality of sliding portions can be achieved, and the position adjustment efficiency of the plurality of second fixing mechanisms 3 connected to the sliding plates 201 can be improved. That is, through this form, it can be ensured that when applied to heat dissipation parts 5 of different sizes, rapid and effective adjustment can be carried out, improving the user experience.

[0087] Based on any of the above embodiments, please refer to Figure 4 , Figure 5 , the second fixing mechanism 3 includes: a bearing plate 302 fixedly connected to the first fixing mechanism 2; a rotating screw 301 threadedly connected to the bearing plate 302; a hinge ring 306 connected to the rotating screw 301, and a plurality of first hinge portions are provided on the circumferential direction of the hinge ring 306; a fixing plate 303, and a plurality of fixing plates 303 are distributed on the circumferential direction of the hinge ring 306. For the fixing plate 303, a second hinge portion is provided, and the first hinge portion and the second hinge portion are connected by a swing rod 307. When the rotating screw 301 rotates relative to the bearing plate 302, the hinge ring 306 can drive the swing rod 307 to swing, so that the plurality of fixing plates 303 move relatively closer to or away from the rotating screw 301 to be able to be clamped in the installation area 51 to achieve locking.

[0088] Among them, the bearing plate 302 is fixedly connected to the first fixing mechanism 2, specifically fixedly connected to the sliding plate 201. After the first fixing mechanism 2 moves into place, the position of the sliding plate 201 is fixed, that is, the position of the corresponding bearing plate 302 is also fixed. The threaded connection between the rotating screw 301 and the bearing plate 302 is specifically that the rotating screw 301 can rotate relative to the bearing plate 302 to change the connection position between the two.

[0089] One or more rotating screws 301 are specifically provided, and the connection position between the rotating screw 301 and the bearing plate 302 can be changed by manually tightening or loosening. This form of manual adjustment can adjust the position of the fixing plate 303 in a fine-tuning manner, with simple and convenient operation and low use cost.

[0090] In a specific embodiment, the rotating screw 301 can be rotated to adjust its position relative to the supporting plate 302, and the corresponding hinge ring 306 fixedly connected to the rotating screw 301 can move as the rotating screw 301 is rotated in and out relative to the supporting plate 302. The multiple first hinge parts arranged circumferentially on the hinge ring 306 and the second hinge parts respectively arranged on the multiple fixed plates 303 are connected by a swing rod 307. When the hinge ring 306 moves, the swing rod 307 can swing to drive the multiple fixed plates 303 to move in the direction close to or away from the rotating screw 301.

[0091] By rotating the screw 301 in a certain direction, the movement of multiple fixing plates 303 can be achieved, and accordingly, the multiple fixing plates 303 can be clamped in the installation area 51, that is, the liquid cooling heat dissipation device can be locked relative to the heat dissipation component 5 of a certain size. When the heat dissipation component 5 is a server component, the liquid cooling heat dissipation device can be locked relative to the server component of a certain size.

[0092] By moving the plurality of fixing plates 303 , the plurality of fixing plates 303 can also be unlocked from the installation area 51 , and the rotating screw 301 can be turned in the opposite direction of the rotation direction when locked.

[0093] In this embodiment, please refer to Figure 5 The first hinge part is a plurality of grooves located on the outer periphery of the hinge ring 306, and a pin is provided in the groove to be hinged to the swing rod 307. The second hinge part is a portion with a pin provided on the side of the fixed plate 303 close to the rotating screw 301. This portion can be protruded from the fixed plate 303. Figure 5 As shown, the swing arm 307 is hinged to the pin arrangement at this location.

[0094] Based on any of the above embodiments, please refer to Figure 5 , and also includes a limiting rod 305 located between the supporting plate 302 and the fixed plate 303, which is used to limit the swing of the swing rod 307. One end of the limiting rod 305 is hinged to the side of the supporting plate 302 close to the fixed plate 303, and the other end of the limiting rod 305 is hinged to the end of the fixed plate 303 close to the supporting plate 302.

[0095] Please refer to Figure 5 After the rotating screw 301 is turned, the limit rod 305 and the swing rod 307 can swing synchronously. By hingedly connecting the limit rod 305 between the fixed plate 303 and the supporting plate 302, the limit rod 305 swings to the position of the supporting plate 302, that is, the maximum limit of rotation, that is, the maximum range in which multiple fixed plates 303 can be relatively separated. This setting can prevent the fixed plate 303 from moving beyond the limit, causing damage to the installation area 51, and affecting the normal operation of the heat dissipation component 5.

[0096] In this embodiment, please refer to Figure 5 , the limiting rods 305 and the swing plates corresponding to the same fixing plate 303 are arranged in parallel, and can swing synchronously to make the corresponding fixing plate 303 approach or move away from the rotating screw 301.

[0097] In this embodiment, a plurality of hinge parts are arranged on one side of the bearing plate 302 close to the fixing plate 303, and the distribution of the plurality of hinge parts is correspondingly arranged with the plurality of hinge parts corresponding to the plurality of fixing plates 303 hinged to the limiting rods 305.

[0098] Based on any of the above embodiments, please refer to Figure 5 , the fixing plate 303 has a first side close to the hinge ring 306 and a second side far from the hinge ring 306, and a protective pad 304 is provided at at least part of the second side.

[0099] In one implementation manner, the protective pad 304 is attached to the surface of the second side and contacts the inner wall of the installation area 51 through the protective pad 304.

[0100] In one implementation manner, as Figure 5 A receiving groove is provided on the second side, and a protective pad 304 for contacting the installation area 51 is provided in the receiving groove.

[0101] In this embodiment, the second side of the fixing plate 303 is used to contact the inner wall of the installation area 51 for clamping, so a protective pad 304 is provided at at least part of the second side. Through the setting of the protective pad 304, firstly, the friction between the fixing plate 303 and the inner wall of the installation area 51 can be increased to ensure reliable clamping, and secondly, the protective effect on the installation area 51 can be ensured in this contact form, avoiding the damage of the heat dissipation part 5 to be dissipated.

[0102] At least part of the position in this embodiment refers to the local part or the entire position of the second side, and can be specifically selected according to the actual situation.

[0103] In this embodiment, the protective pad 304 can be a rubber pad fixed in the receiving groove, which is durable and can provide friction when clamped to the installation area 51, ensuring the stable reliability of the contact between the fixing plate 303 and the installation area 51.

[0104] Based on any of the above embodiments, please refer to Figure 3 , Figure 6 , the liquid cooling mechanism 4 includes: a cold head box 402, one side of the cold head box 402 is used to connect the first fixing mechanism 2, and a heat conduction member 401 for fitting the heat dissipation part 5 to be dissipated is provided on the other side of the cold head box 402; a liquid cooling circulation component, the output end and the input end of the liquid cooling circulation component are both communicated with the inner cavity of the cold head box 402 to be able to provide circulating cooling liquid for the cold head box 402.

[0105] The cold head box 402 has a cavity inside, and a coolant for flowing and circulating is provided in this cavity. Through the contact between the heat conduction member 401 and the component 5 to be cooled, heat can be carried away to achieve the effect of cooling.

[0106] Among them, the heat conduction member 401 has a relatively high thermal conductivity and can quickly conduct heat to the cold head box 402 through contact with the component 5 to be cooled. Specifically, the heat conduction member 401 is fixed at the main heat - generating part of the component 5 to accurately and quickly cool down.

[0107] Based on any of the above - mentioned embodiments, please refer to Figure 6 , the liquid - cooling circulation assembly includes a cooling pipeline 403. The cooling pipeline 403 is arranged between at least two support plates 404 to form multiple sections of serpentine or U - shaped or S - shaped pipelines. For example, the two support parts can be arranged vertically or horizontally. While providing support for the cooling pipeline 403, it is convenient for the cooling pipeline 403 to form multiple sections, which can increase the total length of the cooling pipeline 403, improve the cycle - cooling process, and ensure that there is a sufficient amount of coolant flowing for cooling, ensuring reliable and effective heat dissipation for the component 5 to be cooled and ensuring the service life of the component 5 to be cooled.

[0108] The liquid - cooling circulation assembly further includes a cooling device 406 and a pressurizing device 405 communicated with it. The cooling device 406 is communicated with the inner cavity of the pressurizing device 405 and the cold head box 402 through a second pipeline 408, and the pressurizing device 405 is communicated with the inner cavity of the cold head box 402 through the cooling pipeline 403. The coolant in the cooling device 406 is pressurized by the pressurizing device 405 and then flows into the cold head box 402 through the cooling pipeline 403. After the heat - cold exchange, the coolant in the cold head box 402 flows into the cooling device 406 through the first pipeline 407 for re - cooling and continues to participate in the cycle.

[0109] Based on any of the above - mentioned embodiments, please refer to Figure 1 , it further includes an outer shell 1. The liquid - cooling mechanism 4, the first fixing mechanism 2, and the second fixing mechanism 3 are all arranged inside the outer shell 1. A cooling component is arranged on the outer periphery of the outer shell 1, which can be used to cool the inside of the outer shell 1. The outer shell 1 can specifically be a shell capable of placing the component 5 to be cooled, such as the casing of a server, or a separate shell. This shell is used to cool the component 5 to be cooled inside it alone. Through the setting of the cooling component in cooperation with the liquid - cooling mechanism 4, a reliable and effective heat - dissipation effect for the component 5 to be cooled can be ensured.

[0110] Please refer to Figure 1 、 Figure 7, the temperature reduction assembly includes a blowing member 411, a cleaning member 414 connected to the blowing member 411 through a connecting rod 412, and a filtering member 413 located between the blowing member 411 and the cleaning member 414 and connected to the outer housing 1. The blowing member 411 can rotate to dissipate heat and synchronously drive the cleaning member 414 to clean the filtering member 413.

[0111] As Figure 1 shown, the temperature reduction assembly is specifically connected to a cover plate 410 on the outer housing 1. The cover plate 410 is a component hinged to the outer housing 1, and the blowing member 411 is rotatably connected to the inner wall of the cover plate 410.

[0112] The blowing member 411 can specifically be a fan, and the effect of air-cooled heat dissipation is achieved through the rotation of the fan. The cleaning member 414 rotates with the blowing member 411 to be able to clean the dust and impurities on the filtering member 413, avoid clogging of the filter holes of the filtering member 413, and ensure the reliable effect of the filtering member 413.

[0113] As Figure 7 shown, the cleaning member 414 only occupies a very small area in the middle of the filtering member 413, and both ends of the cleaning member 414 extend to the edge of the filtering member 413. The structure is simple and effective, and the effect of blowing and sweeping can be achieved, with better applicability.

[0114] The cleaning member 414 can be Figure 7 the vertical strip structure shown, or a cross-shaped structure, and can be relatively reliable and stable when rotating for cleaning operations. Through the setting of the cleaning member 414, the outside air can be blown into the interior of the outer housing 1 after being filtered by the filtering member 413, which can ensure.

[0115] For the liquid-cooled heat dissipation device provided by the present application, liquid cooling and air cooling can be carried out through the liquid cooling mechanism 4 and the temperature reduction assembly, effectively avoiding the situation that the components to be cooled 5 in the outer housing 1 are damaged due to overheating and cannot operate normally, and further making the heat dissipation device more secure.

[0116] When the component to be cooled 5 is a server component, for the liquid-cooled heat dissipation device provided by the present application, it can stably fix server components of different sizes in the outer housing 1, and can keep the liquid cooling mechanism 4 and the server components in reliable contact, ensuring the heat dissipation effect of the server components and the service life of the server components.
