Description

Technical Field

[0001] This invention relates to the field of server heat dissipation technology, specifically to a server rack cooling system for computer rooms. Background Technology

[0002] Computer room server rack cooling systems are heat dissipation systems specifically designed for data centers or server racks. They are used to control the internal temperature of the rack and maintain the efficient and stable operation of electronic devices such as servers, preventing hardware performance degradation, shortened lifespan, or even downtime risks caused by high temperatures.

[0003] Heat pipe radiators are commonly used in server rack cooling systems in computer rooms due to their high heat dissipation capabilities. They achieve efficient heat transfer through a cyclical process where the internal working fluid absorbs heat and vaporizes at the evaporation end, releases heat and liquefies at the condensation end, and then flows back through a capillary structure. However, when the temperature of the server rack in the computer room is high, the evaporation rate at the evaporation end of the heat pipe exceeds the rate at which the capillary structure transports the working fluid. At this point, the working fluid in the evaporation end gradually decreases. When the working fluid at the evaporation end completely evaporates, and the capillary structure cannot replenish it in time, the heat pipe will dry-burn. Dry-burning causes a sharp rise in the temperature at the evaporation end, leading to thermal damage to the heat pipe structural materials. Simultaneously, a sudden drop in heat dissipation efficiency causes localized overheating of the equipment, potentially leading to performance degradation of servers and other equipment, shortened component lifespan, or even hardware failure. In severe cases, it can pose a fire hazard.

[0004] To address the aforementioned problems, existing technologies offer several solutions. For example, patent application CN201910804557.3 provides a heat pipe comprising a shell with an internal cavity and a liquid-absorbing core attached to the inner wall of the shell. It also includes a liquid distributor with at least one outlet on its side wall and a thermosensitive liquid outlet assembly corresponding to each outlet. The liquid distributor is installed within the cavity. The thermosensitive liquid outlet assembly is used to close the outlets and is switchable between a closed and an open configuration. This heat pipe can automatically replenish coolant to the evaporator section when it is in a dry-burning state and the temperature has just risen, thereby enhancing the heat exchange performance of the heat pipe and meeting the demand for instantaneous and efficient heat dissipation. However, this solution requires altering the internal structure of the heat pipe. Therefore, the replenishment of coolant affects the internal pressure of the heat pipe, which in turn causes a change in the boiling point of the coolant, affecting the normal heat dissipation of the heat pipe. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling system for server racks in computer rooms, in order to solve the problem that when the temperature of server racks in computer rooms is high, the evaporation rate at the evaporation end inside the heat pipe is greater than the rate at which the working fluid is transported by the capillary structure, leading to dry burning of the heat pipe.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cooling system for a computer room server rack includes fins with multiple heat pipes connected to them. The heat pipes are arranged equidistantly on the fins, with one end of each heat pipe contacting the outer wall of the fin. A motor is fixedly installed on the computer room server rack. A rotating shaft is rotatably connected to one side of each fin, and the motor is connected to the rotating shaft. A connecting rod is provided on the rotating shaft and connected to the heat pipe. A piston is slidably connected inside the connecting rod and fits against the inner wall of the connecting rod. A control switch is provided inside the connecting rod and electrically connected to the motor. The piston contacts the control switch. A thin sheet is provided in the fitting groove and is elastically connected to the inner wall of the fitting groove.

[0008] As is easily understood, when the temperature of a computer room server rack is high, the evaporation rate at the evaporation end of the heat pipe exceeds the rate at which the working fluid is transported by the capillary structure. At this point, the working fluid in the evaporation end gradually decreases. When the working fluid at the evaporation end completely evaporates, and the capillary structure cannot replenish it in time, the heat pipe will dry-burn. This design addresses this by installing a motor on the heat pipe, which controls its rotation. Therefore, when dry-burning occurs, the motor controls the rotation of the heat pipe, switching the two ends of the heat pipe back and forth. The end that is dry-burning is then moved away from the server, preventing damage to the heat pipe. Meanwhile, the working fluid accumulated on the capillary structure flows back to the end closer to the server, continuing to supply power to the server. The device is cooled by a piston inside the connecting rod, which divides the rod into two chambers: one close to the heat pipe and the other away. When the heat pipe burns out, its temperature rises sharply, causing the gas in the chamber closer to the heat pipe to expand and push the piston. After moving a certain distance, the piston contacts a control switch, activating the motor and causing the heat pipe to rotate. This design uses the principle of thermal expansion and contraction to control the piston's movement and thus the motor's start, avoiding temperature detection delays, improving motor start-up response speed, and further preventing the possibility of dry burning in the computer room server rack cooling system.

[0009] Preferably, the heat pipe includes a tube body one and a tube body two, which are perpendicular to each other. Two connecting rods are also perpendicular to each other, and each connecting rod is connected to a tube body one and a tube body two respectively. Fitting grooves are provided on both sides of the fins, and the inner wall of the fitting grooves fits against the outer wall of either tube body one or tube body two. Fitting planes are provided on both tube body one and tube body two, and these fitting planes are perpendicular to each other. A control switch located in the connecting rod on one side of tube body one controls the motor to rotate in reverse, and a control switch located in the connecting rod on one side of tube body two controls the motor to rotate in forward.

[0010] As is easily understood, the larger the contact area between the heat pipe and the server, the more efficiently the heat pipe can dissipate heat from the server, ensuring stable equipment operation and providing crucial support for the heat dissipation needs of high-density data centers. This design features two mutually perpendicular heat pipe bodies, Pipe One and Pipe Two, with contact surfaces on the sides of both bodies. When the heat pipe rotates, the contact surfaces on Pipe One or Pipe Two can contact the server, ensuring the contact area between the heat pipe and the server and guaranteeing the heat dissipation efficiency of the server rack cooling system in the computer room.

[0011] Preferably, two opening and closing fins are provided on each side of the fin, and both opening and closing fins are hinged to the fin. A torsion spring is provided at the hinge point of the opening and closing fin and the fin. One side of the opening and closing fin is attached to tube one or tube two. A T-shaped rod is connected to the rotating shaft. Each of the four opening and closing fins has a sliding groove. A slider is slidably connected to the sliding groove. An opening and closing rod is hinged to one side of the slider. A rotating rod is hinged to one side of the opening and closing rod. A pressing rod is provided on one side of the rotating shaft. The two ends of the pressing rod are hinged to the rotating rods on both sides. The T-shaped rod is in contact with the pressing rod. A limiting rod is also fixedly connected to the fin. The limiting rod is located on the side of the rotating rod away from the rotating shaft, and the limiting rod is in contact with the rotating rod.

[0012] As is easily understood, fins are primarily used to increase the heat dissipation area of ​​the condenser section, quickly dissipating the heat transferred by the heat pipe to the surrounding environment, thereby significantly improving heat dissipation efficiency. Especially in scenarios requiring high-density heat dissipation, such as server racks, fins can effectively optimize heat exchange performance and ensure stable equipment operation. Therefore, this design incorporates opening and closing fins on both sides of the fins. Whenever the heat pipe is about to rotate, the opening and closing fins open, and when the heat pipe has finished rotating, the opening and closing fins close again and adhere to the heat pipe. This ensures that the heat pipe can contact the fins and the opening and closing fins, ensuring that the heat in the heat pipe can be dissipated to the surrounding environment in a timely manner. In this design, a T-shaped rod is installed on the rotating shaft. When the motor starts, the T-shaped rod rotates and presses the pressing rod on one side. At this time, the rotating rods at both ends of the pressing rod rotate around the limiting rod. The rotating rods then pull the opening and closing rod, thereby controlling the opening and closing of the fins. Regardless of which direction the motor rotates, the T-shaped rod will press the pressing rod in one direction. Therefore, no matter which direction the motor rotates, the fins will always unfold. This ensures that whether the motor controls the heat pipe to rotate forward or backward, the fins can open and then close again to fit against the heat pipe. Moreover, this design has a simple and compact structure, reducing manufacturing costs.

[0013] Preferably, the connecting rod is rotatably connected to the rotating shaft, and a long rod is fixedly connected to one end of the piston near the fin. The rotating shaft has four connecting grooves, one end of the long rod extends into the connecting groove, and the long rod fits against the inner wall of the connecting groove.

[0014] It's easy to understand that because the contact area between the server and the server rack cooling system in a computer room is large, some servers will be working while the rest are idle. When the temperature of the working servers is high, some heat pipes may dry-burn, while the rest are working normally. If the motor starts at this time, the shaft will control all heat pipes to rotate, causing even the normally working heat pipes to rotate, thus affecting the normal heat dissipation of the server in the normal temperature area. This design solves the problem by connecting the connecting rod to the shaft and installing a long rod on the piston. When the piston on the side of the dry-burning heat pipe moves, the long rod moves with the piston. At this time, one end of the long rod enters the connecting groove on the shaft. When the motor rotates, it will only drive the dry-burning heat pipe to rotate, without affecting the normal heat dissipation of the other heat pipes. Therefore, this design ensures the heat dissipation efficiency of the computer room server rack cooling system.

[0015] Preferably, the connecting rod includes a telescopic rod one and a telescopic rod two. The telescopic rod one is rotatably connected to the rotating shaft, and the telescopic rod two is slidably connected to the telescopic rod one. The two telescopic rods two are slidably connected to the tube body one and the tube body two, respectively. The piston is slidably connected to the telescopic rod two and is in contact with the inner wall of the telescopic rod two. A spring one is provided between the telescopic rod one and the telescopic rod two. Arc frames are provided on both sides of the fin. Arc frames have arc groove one and arc groove two. The two ends of arc groove two are connected to arc groove one. A movable groove is provided between arc groove one and arc groove two. The two ends of the movable groove... The telescopic rod is connected to the middle of the first and second arc grooves respectively. The two sides of the telescopic rod are fixedly connected to the sliding rod 1. The sliding rod 1 is slidably connected in the first arc groove. The sliding rod 2 is slidably connected to the sliding rod 1. The sliding rod 2 and the sliding rod 1 are provided with the spring 2. The arc frame is fixedly connected to the limiting block 1. One end of the sliding rod 2 is in contact with the piston. The other end extends to the outside of the sliding rod 1 and is in contact with the limiting block 1. The two ends of the arc groove 2 are hinged to the limiting block 2. The hinge of the limiting block 2 and the arc frame is provided with the torsion spring. The arc frame restricts the limiting block 2 from rotating in the arc groove 2.

[0016] As is easily understood, this design uses two connecting rods: a telescopic rod 1 and a telescopic rod 2. When the heat pipe experiences dry burning, the piston moves inside the telescopic rod 2. After the piston moves a certain distance, the sliding rod 2 is pulled back into the sliding rod 1 by the spring 2. At this time, the spring 1 pulls the telescopic rod 2, and the sliding rod 1 passes through the moving groove from the arc groove 1 to the arc groove 2. The telescopic rod 2 drives the tube body 2 to move away from the server. When the shaft rotates, the shaft will drive the telescopic rod 1 to rotate, and the sliding rod 1 will enter the arc groove 2 along the arc groove 1. Finally, the telescopic rod 2 will drive the tube body 2 to the position of the fins, while the tube body 1 on the other side will follow the telescopic rod 2 along the arc groove 1 directly to the position of the server and make contact with the server. Therefore, this design ensures that the tube body 1 and tube body 2 move away from the server before rotating, avoiding the corner friction and compression of the server at the connection point of the tube body 1 and tube body 2. This ensures that the server rack cooling system in the computer room will not damage the server during operation and improves the reliability of the server rack cooling system in the computer room.

[0017] Preferably, each of the four connecting slots is rotatably connected to a second long rod. The first long rod is provided with a protrusion. The protrusions on the two first long rods on the same horizontal plane are mirror images of each other. The protrusions are in contact with the second long rod. The second long rod is provided with an arc that is consistent with the surface of the rotating shaft.

[0018] It's easy to understand that after a computer room server rack cooling system has been running for a period of time, some heat pipes may come into contact with the server, while others may come into contact with the server. If both heat pipes experience dry burning, the long rods inside the telescopic rods on both heat pipes will enter the connecting grooves on the rotating shaft. If the motor starts at this time, the heat pipes and fins will jam. Therefore, this design addresses this by installing long rods inside each connecting groove and mirroring the protrusions on the two long rods on the same horizontal plane. When the long rod in the heat pipe in the same direction moves into the connecting groove, the protrusion on the first long rod will push the second long rod to rotate. Since the second long rod is arc-shaped, the protrusion on the first long rod of the heat pipe in other directions will be blocked by the second long rod and cannot enter the connecting groove. At this time, the motor will drive the heat pipe in the same direction to rotate first. After the rotation is completed, the first long rod leaves the connecting groove. Only then can the first long rod of the heat pipe in other directions enter the connecting groove. The motor will then start again to control the rotation of the heat pipe in other directions. Therefore, this design avoids the situation where the heat pipe and fins jam, and improves the service life of the cooling system of the computer room server rack.

[0019] Preferably, a gripper is fixedly connected to one end of the telescopic rod 2, and thermally conductive silicone is provided between the gripper and the telescopic rod 2. The grippers on the two telescopic rods 2 are slidably connected to the tube body 1 and the tube body 2, respectively.

[0020] As is easily understood, the heat pipe must be in close contact with the server to ensure that heat from the server can be transferred to the heat pipe. This design uses a clamp fixedly connected to one end of the telescopic rod two, and thermally conductive silicone is placed between the clamp and the telescopic rod two. Since the thermally conductive silicone has a certain degree of elasticity, whenever the first or second tube body rotates onto the server, the telescopic rod two will squeeze the thermally conductive silicone, thereby causing the clamp to press the first or second tube body, ensuring that the first or second tube body is in close contact with the server, and thus ensuring the heat dissipation efficiency of the server rack cooling system in the computer room.

[0021] Preferably, the T-shaped rod has three arc blocks evenly distributed around its circumference. The arc blocks contact the pressing rod. The T-shaped rod is rotatably connected to the rotating shaft. Gear 1 is fixedly connected to the T-shaped rod, and gear 2 is fixedly connected to the rotating shaft. Gear 3 and gear 4 are rotatably connected to one side of the rotating shaft. Gear 3 and gear 4 are both fixedly connected to the motor output end. Gear 3 and gear 4 mesh with gear 1 and gear 2 respectively. The transmission ratio of gear 2 and gear 4 is 1:1, and the transmission ratio of gear 1 and gear 3 is 3:4.

[0022] As is easily understood, since the rotation of both the T-shaped rod and the heat pipe is controlled by the motor, the opening of the fins and the rotation of the heat pipe are synchronized when the motor starts. Because the fins are in contact with the heat pipe surface when closed, and the opening direction of the fins is different from the rotation direction of the heat pipe, the fins may interfere with and rub against the heat pipe when they operate synchronously. This can affect the normal operation of the fins and heat pipe, and may even cause wear on the surface of the heat pipe or the fins. Therefore, this design uses a gear one fixedly connected to the T-shaped rod and a gear two fixedly connected to the rotating shaft. The motor will then... The gear meshing method transmits power to the T-shaped rod and the rotating shaft. Since the transmission ratio of gear two and gear four is 1:1, and the transmission ratio of gear one and gear three is 3:4, the opening speed of the opening fins is greater than the rotation speed of the heat pipe. Therefore, this design avoids interference and friction between the opening fins and the heat pipe when the motor starts. In addition, the design also has an arc block on the T-shaped rod. When the T-shaped rod rotates continuously, the arc block will continuously squeeze and press the rod to keep the opening fins at the maximum opening angle until the heat pipe completes rotation. Therefore, this design further avoids friction between the opening fins and the heat pipe, and improves the service life of the opening fins and the heat pipe.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention incorporates a motor on the heat pipe, which controls the rotation of pipe body one and pipe body two. Therefore, when pipe body one or pipe body two experiences dry burning, the motor controls the rotation of the heat pipe, switching the two ends of the heat pipe back and forth. At this time, the end that is dry burning will be moved away from the server, preventing damage to the heat pipe caused by dry burning. Meanwhile, the working fluid accumulated on the capillary structure will flow back to the end closer to the server to continue cooling the server. This not only prevents damage to the heat pipe but also ensures the cooling efficiency of the computer room server rack cooling system.

[0025] 2. This invention also incorporates a piston inside the connecting rod. When the heat pipe experiences dry burning, the heat of the heat pipe increases dramatically, and the gas inside the chamber near the heat pipe expands and pushes the piston. After moving a certain distance, the piston contacts the control switch, at which point the motor starts and controls the rotation of the heat pipe. Therefore, this design controls the movement of the piston and thus the start of the motor through the principle of thermal expansion and contraction, avoiding the delay in temperature detection, improving the response speed of motor start-up, and further preventing the possibility of dry burning in the cooling system of the computer room server rack.

[0026] 3. The present invention designs the heat pipe as two perpendicular tube bodies, and provides a contact surface on the side of both tube bodies. When the heat pipe rotates, the contact surface on tube body one or tube body two can contact the server, ensuring the contact area between the heat pipe and the server and ensuring the heat dissipation efficiency of the server rack cooling system in the computer room.

The control switch 11 located in the connecting rod 8 on the side of the tube body 4 controls the motor to rotate in reverse. The control switch 11 located in the connecting rod 8 on the side of the tube body 5 controls the motor to rotate in forward.

[0037] For further details, please refer to Figures 1 to 7Two opening / closing fins 12 are provided on both sides of fin 1. Both opening / closing fins 12 are hinged to fin 1. A torsion spring is provided at the hinge point between the opening / closing fin 12 and fin 1. One side of the opening / closing fin 12 is attached to tube body 4 or tube body 5. A T-shaped rod 13 is connected to the rotating shaft 7. Each of the four opening / closing fins 12 has a sliding groove 18. A slider 19 is slidably connected to the sliding groove 18.

The T-shaped rod 13 is in contact with the pressing rod 14. A limiting rod 16 is also fixedly connected to the fin 1. The limiting rod 16 is located on the side of the rotating rod 15 away from the rotating shaft 7, and the limiting rod 16 is in contact with the rotating rod 15. The connecting rod 8 is rotatably connected to the rotating shaft 7. A long rod 20 is fixedly connected to one end of the piston 10 near the fin 1. Four connecting grooves 21 are opened on the rotating shaft 7. One end of the long rod 20 extends into the inside of the connecting groove 21, and the long rod 20 fits against the inner wall of the connecting groove 21.

[0038] Please see Figures 1 to 7 The connecting rod 8 includes a telescopic rod 1 22 and a telescopic rod 23. The telescopic rod 1 22 is rotatably connected to the rotating shaft 7, and the telescopic rod 23 is slidably connected to the telescopic rod 1 22. The two telescopic rods 23 are slidably connected to the tube body 1 4 and the tube body 2 5, respectively. The piston 10 is slidably connected to the telescopic rod 23, and the piston 10 is in contact with the inner wall of the telescopic rod 23. A spring 1 24 is provided between the telescopic rod 1 22 and the telescopic rod 23. Arc frames 25 are provided on both sides of the fin 1. Arc grooves 1 26 and 27 are provided on the arc frames 25. The two ends of the arc groove 27 are connected to the arc groove 1 26. A moving groove 28 is provided between the arc groove 1 26 and the arc groove 27. The two ends of the moving groove 28 are respectively connected to the arc groove 1 26 and the arc groove 27. The first arc groove 26 and the second arc groove 27 are connected in the middle. The two sides of the second telescopic rod 23 are fixedly connected to the first sliding rod 29. The first sliding rod 29 is slidably connected in the first arc groove 26. The second sliding rod 30 is slidably connected on the first sliding rod 29. The second spring 31 is provided between the second sliding rod 30 and the first sliding rod 29. The first limiting block 32 is fixedly connected on the arc frame 25. One end of the second sliding rod 30 contacts the piston 10, and the other end extends to the outside of the first sliding rod 29 and contacts the first limiting block 32. The two ends of the second arc groove 27 are hinged to the second limiting block 33. The hinge point between the second limiting block 33 and the arc frame 25 is provided with a torsion spring. The arc frame 25 restricts the second limiting block 33 from rotating in the second arc groove 27.

[0039] Please see Figures 1 to 7Each of the four connecting slots 21 is rotatably connected to a second long rod 34. A protrusion 37 is provided on the first long rod 20. The protrusions 37 on the two first long rods 20 on the same horizontal plane are mirror images of each other. The protrusions 37 contact the second long rod 34. The second long rod 34 has an arc shape consistent with the surface of the rotating shaft 7. One end of the telescopic rod 23 is fixedly connected to a clamp 35. Thermally conductive silicone 36 is provided between the clamp 35 and the telescopic rod 23. The clamps 35 on the two telescopic rods 23 are slidably connected to the tube body 4 and the tube body 5, respectively. Three arc blocks 42 are provided on the T-shaped rod 13. Block 42 is evenly distributed around the circumference of T-shaped rod 13. The arc block 42 contacts the pressing rod 14. T-shaped rod 13 is rotatably connected to rotating shaft 7. Gear 1 38 is fixedly connected to T-shaped rod 13. Gear 2 39 is fixedly connected to rotating shaft 7. Gear 3 40 and Gear 41 are rotatably connected to one side of rotating shaft 7. Gear 3 40 and Gear 41 are both fixedly connected to the motor output end. Gear 3 40 and Gear 41 mesh with gear 1 38 and gear 2 39 respectively. The transmission ratio of gear 2 39 and gear 41 is 1:1, and the transmission ratio of gear 1 38 and gear 3 40 is 3:4.

[0040] Please see Figures 1 to 7When heat pipe 2 experiences dry burning, the piston 10 inside telescopic rod 23 is pushed, and the long rod 20 at one end of piston 10 moves with piston 10. The protrusion 37 at one end of long rod 20 passes through telescopic rod 22 and contacts long rod 34 on rotating shaft 7, pushing long rod 34 to rotate and enter connecting groove 21. After piston 10 moves, piston 10 will move away from sliding rod 30. At this time, sliding rod 30 loses the support of piston 10 and is pulled back into sliding rod 29 by spring 31. At this time, spring 24 pulls telescopic rod 23, and telescopic rod 23 lifts tube body 25 through clamp 35, making tube body 25 away from the server, while tube body 4 on the other side... Sliding along the gripper 35, and at this time, the sliding rod 29 on the telescopic rod 23 moves along the moving groove 28 from the arc groove 26 into the arc groove 27. After the piston 10 moves a certain distance, it will contact the control switch 11 on the telescopic rod 23. At this time, the motor starts, and the motor output drives the gear 38 to rotate through the gear 40, which in turn causes the T-shaped rod 13 to rotate. The motor output drives the gear 39 to rotate through the gear 41, which in turn causes the rotating shaft 7 to rotate. During the rotation of the T-shaped rod 13, the arc block 42 on the T-shaped rod 13 will press the pressing rod 14 on one side. After being pressed, the pressing rod 14 moves to one side, and the rotating rod 15 hinged at both ends of the pressing rod 14 is pressed by the limiting rod 16. As the rotating rod 15 rotates around the limit, the opening / closing rod 17, hinged at one end, is pulled. This causes the opening / closing rod 17 to pull the slider 19 downwards along the sliding groove 18 while simultaneously pulling the slider 19 to one side. Consequently, the opening / closing fin 1 rotates around the fin 1. During the rotation of the rotating shaft 7, the two telescopic rods 22 and 23 rotate. The two telescopic rods 23 then drive the tube body 4 and tube body 5 to rotate around the rotating shaft 7, respectively. At this time, the sliding rod 29 on one side of tube body 5 moves a certain distance along the arc groove 26, then presses against the limit block 33 and enters the arc groove 27. It then slides along the arc groove 27 to its end, and the sliding rod 30 is subjected to... As the inner walls of the first arc groove 26 and the second arc groove 27 are compressed, the telescopic rod 23 is gradually stretched. After the sliding rod 29 slides to the end of the second arc groove 27, the tube 25 will squeeze the thin sheet 6 inside the bonding groove 9 and enter the bonding groove 9. Meanwhile, the sliding rod 29 on the other side of the tube 4 will continue to move along the first arc groove 26 until the bonding surface 3 on the tube 4 contacts the server. After the tube 25 enters the bonding groove 9, the piston 10 inside the telescopic rod 23 on one side of the tube 25 gradually returns to its original position. The long rod 20 also moves with the piston 10 and moves away from the connecting groove 21. At this time, the motor stops rotating, and the opening and closing fins 1 are reset by the torsion spring and contact the tube 25.
