DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] The present invention provides a CPU liquid cooling radiator assembly for a server, as Figure 1 and Figure 2As shown, it includes a heat-absorbing base 1, a heat dissipation component 2 and a circulating water pipe 3; the CPU of the server is installed on the heat-absorbing base 1, the circulating water pipe 3 is connected to a circulating water pump, and the circulating water pump circulates the cold water for heat dissipation inside the circulating water pipe 3. The circulating water pipe 3 is installed inside the heat-absorbing base 1 and correspondingly penetrates through the heat dissipation component 2. The heat dissipation component 2 is composed of multiple heat dissipation fins, and the tops of the multiple heat dissipation fins are welded using a heat-conducting material. Among them, both the heat dissipation fins and the heat-conducting material are made of copper metal material to ensure the heat dissipation effect of the heat dissipation component 2. A lifting component is placed at the bottom of the heat dissipation component 2; during the operation of the CPU, the heat-absorbing base 1 continuously absorbs the heat generated by the CPU. At this time, the circulating water pump works, and the cold water enters and flows inside the heat-absorbing base 1 through the circulating water pipe 3. After the water that has absorbed heat enters the heat dissipation component 2, the heat dissipation component 2 dissipates heat through multiple juxtaposed heat dissipation fins to ensure the heat dissipation effect of the heat dissipation component 2.

[0019] The lifting component includes a first bottom frame 4, a second bottom frame 5, an inner frame 6, a rotating plate 7 and a moving component inside the inner frame 6. The first bottom frame 4 and the second bottom frame 5 are placed horizontally side by side, and the heat dissipation component 2 is correspondingly placed on the tops of the first bottom frame 4 and the second bottom frame 5. The outer end of the inner frame 6 is connected to the inner side surface of the first bottom frame 4. The rotating plate 7 is installed on the top of the inner frame 6 using a twisting component. The moving component makes the rotating plate 7 rotate through the twisting component, and the rotating rotating plate 7 lifts the heat dissipation component 2 on the tops of the first bottom frame 4 and the second bottom frame 5. The heat dissipation component 2 is installed on the tops of the first bottom frame 4 and the second bottom frame 5 of the lifting component. The first bottom frame 4 and the second bottom frame 5 limit the heat dissipation component 2 using a clamping component. At this time, the moving component of the lifting component moves inside the inner frame 6, and the moving moving component makes the rotating plate 7 rotate through the twisting component. The top end of the rotating rotating plate 7 gradually contacts the bottom surface of the heat dissipation component 2. The continuously rotating rotating plate 7 pushes the heat dissipation component 2 to move upward on the tops of the first bottom frame 4 and the second bottom frame 5, so that the heat dissipation component 2 is separated from the first bottom frame 4 and the second bottom frame 5, improving the heat dissipation effect at the bottom of the heat dissipation component 2 and preventing the first bottom frame 4 and the second bottom frame 5 from blocking the heat dissipation at the bottom of the heat dissipation component 2.

[0020] In Figure 2 and Figure 3Among them, the moving component includes an insertion bar 8, a support rod 9, and a bottom groove 10; the bottom groove 10 is at the bottom of the inner side end of the inner frame 6, the outer side end of the insertion bar 8 is connected to the inner side surface of the second bottom frame 5, the support rod 9 is fixed to the inner side end of the insertion bar 8, the insertion bar 8 is movably placed inside the bottom groove 10, a sliding groove 11 is provided inside the inner frame 6, the moving support rod 9 slides inside the sliding groove 11, and the bottom surface of the rotating plate 7 is in contact with the top surface of the support rod 9. At the center of the inner side surface of the first bottom frame 4, a cylinder 12 is installed, and the output end of the cylinder 12 is drivingly connected to the center of the inner side surface of the second bottom frame 5. Before installing the cylinder 12, the first bottom frame 4 and the second bottom frame 5 are arranged in parallel, the insertion bar 8 corresponds to the inner frame 6. At this time, the first bottom frame 4 is sleeved on the outer side of the insertion bar 8 of the second bottom frame 5 by using the bottom groove 10 of the inner frame 6, and the top end of the support rod 9 is in contact with the bottom surface of the rotating plate 7. Until the first bottom frame 4 and the second bottom frame 5 are parallel and corresponding, the cylinder 12 is installed between the first bottom frame 4 and the second bottom frame 5.

[0021] When the cylinder 12 works and the output end of the cylinder 12 makes the second bottom frame 5 move away from the first bottom frame 4, the moving second bottom frame 5 pulls the insertion bar 8 to slide inside the bottom groove 10, the insertion bar 8 drives the support rod 9 to slide inside the sliding groove 11 of the inner frame 6, the moving support rod 9 slides on the bottom surface of the rotating plate 7, and the moving support rod 9 makes the rotating plate 7 rotate on the top of the inner frame 6.

[0022] In Figures 2 to 4 Among them, the twisting component includes a moving frame 13, an insertion rod 14, a spring piece 15, and a support 16; the support 16 is fixedly installed on the top surface of the inner side part of the inner frame 6, and the moving frame 13 is on the outer side part of the support 16. The insertion rod 14 is installed on the inner side part of the moving frame 13 and penetrates through the support 16 correspondingly, and the moving frame 13 is connected to the support 16 by the spring piece 15. The moving frame 13 is composed of two toothed plates and a push plate. Tooth plates are fixed at both ends of the push plate, the inner side surface of the toothed plate is in contact with the side of the support 16, and the insertion rod 14 is connected to the push plate. The moving moving frame 13 drives the push plate to approach or move away from the support 16. At the bottom end of the rotating plate 7, a gear 17 is fixed by a connecting rod. The rotating plate 7 is rotationally matched with the top of the support 16 by the connecting rod. The two gears 17 correspond to the two toothed plates one by one, and the gear 17 meshes with the toothed plate. When the first bottom frame 4 and the second bottom frame 5 are separated from each other, the moving insertion bar 8 makes the rotating plate 7 rotate by using the support rod 9. The rotating rotating plate 7 rotates on the top of the support 16 by using the connecting rod, and the rotating plate 7 drives the gear 17 to rotate clockwise by using the connecting rod. The clockwise rotating gear 17 makes the moving frame 13 move away from the second bottom frame 5 by using the toothed plate. The moving moving frame 13 makes the push plate approach the support 16. At this time, the push plate and the support 16 cooperate to squeeze the spring piece 15, and the insertion rod 14 makes the push plate smoothly approach the support 16 to prevent the moving frame 13 from shifting on the top of the inner frame 6.

[0023] The support of the support rod 9 causes the rotating plate 7 to be inclined. At this time, the movement of the support rod 9 causes the rotating plate 7 to rotate clockwise on the top of the inner frame 6 by using the twisting component. The top end of the rotating plate 7 rotating clockwise gradually contacts the bottom of the heat dissipation component 2. The rotating rotating plate 7 is used to move the heat dissipation component 2 upward, ensuring the heat dissipation space at the bottom of the heat dissipation component 2 and improving the heat dissipation effect at the bottom of the heat dissipation component 2.

[0024] In Figure 2 and Figure 5 , two opposite stretching components are arranged between the first bottom frame 4 and the second bottom frame 5. The stretching components include a first swing plate 18, a second swing plate 19, an intermediate rod 20 and a limiting rod 21; the inner ends of the first swing plate 18 and the second swing plate 19 are rotatably connected by the intermediate rod 20. Side plates are fixed on the inner side surfaces of the first bottom frame 4 and the second bottom frame 5. The limiting rod 21 is fixed on the top surface of the side plate. Sleeve 22 is provided at the outer ends of the first swing plate 18 and the second swing plate 19, and the sleeve 22 is sleeved on the surface of the limiting rod 21. An arc-shaped frame 23 is fixed at the inner end of the first swing plate 18. The arc-shaped frame 23 is made of rubber material. An arc-shaped plate 24 is fixed at the inner end of the second swing plate 19. The arc-shaped plate 24 is at the bottom of the arc-shaped frame 23. A vertical rod 25 passing through the arc-shaped frame 23 is fixed at the top end of the arc-shaped plate 24. The vertical rod 25 is connected to the inner end of the arc-shaped frame 23 by an elastic strip 26. Since the vertical rod 25 at the top of the arc-shaped plate 24 is slidably inserted into the arc-shaped frame 23, when the cylinder 12 works to separate the first bottom frame 4 and the second bottom frame 5, the two stretching components cooperate to limit the first bottom frame 4 and the second bottom frame 5. At this time, the side plate drives the sleeve 22 to move by using the limiting rod 21. The first swing plate 18 and the second swing plate 19 both rotate on the surface of the intermediate rod 20. At this time, the included angle between the first swing plate 18 and the second swing plate 19 gradually expands. The arc-shaped plate 24 moves inside the arc-shaped frame 23 by using the vertical rod 25. The vertical rod 25 and the arc-shaped frame 23 cooperate to squeeze the elastic strip 26. During the separation process of the first bottom frame 4 and the second bottom frame 5, the rotation of the first swing plate 18 and the second swing plate 19 provides stable support for the separation of the first bottom frame 4 and the second bottom frame 5, so as to facilitate the inner frame 6 to slide smoothly on the surface of the insert bar 8 by using the bottom groove 10 and avoid the deviation of the first bottom frame 4 and the second bottom frame 5 during the separation process.

[0025] In Figure 1 and Figure 2In it, openings are provided on the top surfaces of the first bottom frame 4 and the second bottom frame 5. Two shelf plates 27 are provided inside the openings, and a cross bar for limiting the shelf plates 27 is fixed inside the openings. A screw rod 28 penetrates through the centers of the first bottom frame 4 and the second bottom frame 5. The shelf plates 27 are spirally sleeved on the surface of the screw rod 28. The screw rod 28 is located at the center of the two cross bars. The rotating screw rod 28 causes the two shelf plates 27 to approach or move away from each other. After the heat dissipation component 2 is placed on the tops of the first bottom frame 4 and the second bottom frame 5 of the lifting component, the screw rod 28 is screwed. The rotating screw rod 28 causes the two shelf plates 27 to approach each other until the two shelf plates 27 cooperate to limit the heat dissipation component 2. The inner side surfaces of the shelf plates 27 are attached to the side surfaces of the heat dissipation component 2, which is convenient for installing heat dissipation components 2 of different lengths on the top of the lifting component.

[0026] When the lifting component moves the heat dissipation component 2 upward, the upward moving heat dissipation component 2 moves on the inner side surface of the shelf plate 27, and the four shelf plates 27 limit the heat dissipation component 2 to prevent the heat dissipation component 2 from deviating from the lifting component during the upward movement.

[0027] The present invention also provides a liquid-cooled radiator, including the CPU liquid-cooled radiator component for the server described above.

[0028] The working principle of the present invention: Refer to Figures 1 to 5 As shown, after the heat dissipation component 2 is placed on the tops of the first bottom frame 4 and the second bottom frame 5 of the lifting component, the screw rod 28 is screwed. The rotating screw rod 28 causes the two shelf plates 27 to approach each other until the two shelf plates 27 cooperate to limit the heat dissipation component 2. The inner side surfaces of the shelf plates 27 are attached to the side surfaces of the heat dissipation component 2.

[0029] When the air cylinder 12 works and the output end of the air cylinder 12 causes the second bottom frame 5 to move away from the first bottom frame 4, the moving second bottom frame 5 pulls the insertion bar 8 to slide inside the bottom groove 10, and the insertion bar 8 drives the support rod 9 to slide inside the chute 11 of the inner frame 6. The moving insertion bar 8 causes the rotating plate 7 to rotate through the support rod 9. The rotating rotating plate 7 rotates on the top of the bracket 16 through the connecting rod, and the rotating plate 7 drives the gear 17 to rotate clockwise through the connecting rod. The clockwise rotating gear 17 causes the moving frame 13 to move away from the second bottom frame 5 through the toothed plate. The moving moving frame 13 causes the push plate to approach the bracket 16. At this time, the push plate and the bracket 16 cooperate to squeeze the elastic piece 15, and the insertion rod 14 causes the push plate to approach the bracket 16 stably, preventing the moving frame 13 from deviating on the top of the inner frame 6.

[0030] The support of the support rod 9 causes the rotating plate 7 to be inclined. At this time, the movement of the support rod 9 causes the rotating plate 7 to rotate clockwise on the top of the inner frame 6 through the twisting component. The top end of the clockwise rotating rotating plate 7 gradually contacts the bottom of the heat dissipation component 2, and the rotating rotating plate 7 causes the heat dissipation component 2 to move upward, ensuring the heat dissipation space at the bottom of the heat dissipation component 2.

[0031] Since the vertical rod 25 at the top of the arc-shaped plate 24 is slidably inserted into the arc-shaped frame 23, when the cylinder 12 works to separate the first bottom frame 4 and the second bottom frame 5, the two stretching components cooperate to limit the first bottom frame 4 and the second bottom frame 5. At this time, the side plate drives the sleeve 22 to move by using the limiting rod 21. The first swing plate 18 and the second swing plate 19 both rotate on the surface of the middle rod 20. At this time, the included angle between the first swing plate 18 and the second swing plate 19 gradually expands. The arc-shaped plate 24 moves inside the arc-shaped frame 23 by using the vertical rod 25. The vertical rod 25 and the arc-shaped frame 23 cooperate to squeeze the elastic strip 26. During the separation process of the first bottom frame 4 and the second bottom frame 5, the rotation of the first swing plate 18 and the second swing plate 19 provides stable support for the separation of the first bottom frame 4 and the second bottom frame 5, so as to facilitate the inner frame 6 to slide smoothly on the surface of the insertion strip 8 by using the bottom groove 10, and avoid the deviation of the first bottom frame 4 and the second bottom frame 5 during the separation process.

[0032] During the operation of the CPU, the heat absorption base 1 continuously absorbs the heat generated by the CPU. At this time, the circulating water pump works, and the cold water enters the heat absorption base 1 through the circulating water pipe 3 and flows inside. After the water that has absorbed heat enters the heat dissipation component 2, the heat dissipation component 2 dissipates heat through a plurality of heat dissipation fins arranged in parallel to ensure the heat dissipation effect of the heat dissipation component 2.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
