Data center heat pipe heat exchange structure

Abstract

This invention relates to the field of data center heat exchange devices, specifically a data center heat pipe heat exchange structure. It includes a heat exchanger shell with a heat exchange chamber on its inner wall. Several heat exchange tubes are vertically and movably installed inside the heat exchange chamber. The structure also includes an adjustment mechanism movably installed at the lower part of the heat exchanger shell to drive the movement of the heat exchange tubes, and an exhaust mechanism located inside the heat exchange tubes for gas guidance. This data center heat pipe heat exchange structure achieves a combined lifting and rotating motion of the heat exchange tubes by driving an impeller with water pressure from the inlet pipe. The spiral heat exchange tubes, in conjunction with adjusting pins and adjusting spiral grooves, continuously agitate the heat-carrying liquid inside the chamber, constantly flushing and stripping the thermal boundary layer on the tube wall. The spiral grooves and spiral guide plates inside the tubes extend the flow path of the evaporator, resulting in more complete phase change heat absorption. Simultaneously, the partitions achieve stratified heat exchange, with the heat-carrying liquid flowing from bottom to top and the evaporator flowing in a cross-coupled direction. Compared to traditional fixed heat pipe structures, the overall heat exchange capacity is significantly enhanced.

Description

Technical Field

[0001] This invention relates to the field of data center heat exchange devices, specifically a data center heat pipe heat exchange structure. Background Technology

[0002] With the rapid development of the digital economy and the continuous expansion of data center computing power, the high-density operation of equipment such as servers and switches generates a large amount of waste heat. Prolonged high-temperature operation of these devices can easily lead to problems such as reduced computing frequency and hardware aging and damage. Therefore, an efficient and stable heat dissipation system is a core supporting facility for ensuring the safe and long-term operation of data centers. Currently, heat pipe phase change heat transfer solutions, with their advantages of large latent heat of phase change, good temperature uniformity, and low energy consumption, have gradually replaced traditional air cooling and single water cooling modes and are widely used in medium and large-scale data center heat dissipation scenarios.

[0003] The following problems remain unresolved in existing technologies: 1. Static fixed arrangement of heat exchange tubes makes it difficult to break the fluid heat exchange boundary layer, limiting heat exchange efficiency. Conventional heat pipe heat exchangers typically have rigidly fixed heat exchange tubes. When the heat-carrying liquid flows smoothly in a laminar flow within the heat exchange chamber, a static high-temperature liquid thermal boundary layer forms on the outer wall of the heat exchange tubes, hindering heat transfer between the tube wall and the fluid. Even with the addition of simple baffles to some devices, only overall fluid disturbance is achieved, failing to specifically flush the boundary layer on the outer wall of each heat exchange tube, resulting in low utilization of the heat exchange area. 2. Poor gas-liquid separation of the evaporator inside the heat exchange tubes leads to frequent liquid accumulation and gas blockage. Furthermore, the long-term adhesion of accumulated vapor bubbles to the tube wall creates a gas film thermal resistance, significantly hindering heat conduction between the tube wall and the evaporator, thus affecting heat exchange efficiency. Summary of the Invention

[0005] Preferably, the adjustment mechanism includes a drive chamber located at the lower part of the heat exchanger shell, and a drain pipe is vertically fixedly connected to the middle of the inner wall of the drive chamber. An impeller for driving the heat exchange tube to move upward is rotatably arranged in the middle of the drain pipe. A partition plate is fixedly installed in the middle of the heat exchange chamber. The heat exchange tubes are vertically inserted through the surface of the partition plate, and an adjustment spiral groove is opened inside the partition plate. An adjustment pin that slides in cooperation with the adjustment spiral groove is fixedly connected to the surface of the heat exchange tubes. An inlet pipe is eccentrically installed at the lower part of the heat exchanger shell and communicates with the drive chamber. A U-shaped pipe communicating with the drive chamber and the heat exchange chamber is fixedly connected to the middle part of the heat exchanger shell. A drain pipe communicating with the heat exchange chamber is fixedly connected to the upper part of the side wall of the heat exchanger shell.

[0006] Preferably, the heat exchange chamber has insertion holes at the top and bottom, and the two ends of the heat exchange tube are respectively inserted into the two insertion holes. Both ends of the heat exchange tube are fixedly connected with gaskets, and the two gaskets are slidably disposed inside the two insertion holes. A compression spring is fixedly connected between the inner wall of the insertion hole and the surface of the gasket. A telescopic bellows is fixedly connected to the side wall of the lower gasket ring. The lower end of the telescopic bellows extends into the interior of the heat exchange tube. A drain bracket is fixedly connected to the lower part of the inner wall of the heat exchanger shell. The middle part of the drain bracket is fixedly connected to the surface of the drain pipe. The upper end of the telescopic bellows is fixedly connected to the surface of the drain bracket.

[0007] Preferably, a buffer bellows is fixedly connected to the top of the heat exchange tube, and a liquid delivery cone sleeve is installed on the top of the buffer bellows via a bearing. The liquid delivery cone sleeve is fixedly installed on the top of the heat exchanger shell. The bottom of the heat exchange tube is an arc surface, the top surface of the impeller blades is provided with an inclined surface that matches the bottom of the heat exchange tube, and the middle part of the heat exchange tube is spiral.

[0008] Preferably, the partition plate has a circular hole in the middle for installing the heat exchange tube, the adjusting spiral groove is formed on the inner wall of the circular hole, and the end of the adjusting pin near the inner wall of the adjusting spiral groove is spherical.

[0009] Preferably, the exhaust mechanism includes a flow-guiding spiral groove formed on the inner wall of the heat exchange tube, and an exhaust pipe is vertically fixedly connected to the middle of the inner wall of the heat exchange tube. An air guide hole is inclinedly opened on the surface of the exhaust pipe. A spiral guide plate that matches the spiral groove is fixedly connected to the surface of the exhaust pipe. A telescopic pipe is rotatably connected to the top of the exhaust pipe, and the upper part of the telescopic pipe is fixedly connected to the surface of the exhaust bracket.

[0010] Preferably, the lower part of the telescopic tube is movably connected to the top of the exhaust pipe via a connecting bearing, and the top of the telescopic tube extends through the infusion cone sleeve to the exhaust bracket position at the top of the heat exchanger housing.

[0011] Preferably, the top of the heat exchanger shell, located at the liquid delivery cone sleeve, is designated as the evaporator liquid delivery chamber, and the bottom of the heat exchanger shell, located at the lower end of the drain pipe, is designated as the evaporator liquid discharge chamber.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the impeller is driven by the water pressure of the inlet pipe to achieve a combined lifting and rotating motion of the heat exchange tube. The spiral heat exchange tube, in conjunction with the adjusting pin and adjusting spiral groove, continuously agitates the heat-carrying liquid inside the cavity, constantly flushing and peeling away the thermal boundary layer on the tube wall. The flow-guiding spiral groove and spiral guide plate inside the tube extend the flow path of the evaporator, resulting in more complete phase change heat absorption. At the same time, the baffle plate achieves stratified heat exchange of the fluid, with the heat-carrying liquid entering from the bottom and exiting from the top, and the flow direction of the evaporator being cross-coupled. Compared with the traditional fixed heat pipe structure, the overall heat exchange capacity is significantly enhanced.

[0013] In this invention, the coordinated design of the exhaust pipe, inclined air guide hole, and spiral guide plate in the exhaust mechanism allows the evaporating liquid to flow downward along the spiral groove curve, extending the flow path to fully absorb heat and vaporize. The vaporized steam quickly flows into the exhaust pipe through the inclined air guide hole and is discharged upward. At the same time, the reciprocating up and down vibration of the heat exchange tube can destroy the phenomenon of steam adhering to the wall and avoid the formation of gas film, greatly enhancing the phase change heat efficiency inside the tube, and ensuring that the steam is discharged in time and sent to the downstream condensation and recovery.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 10 This invention provides a technical solution: a data center heat pipe heat exchange structure, including a heat exchanger shell 1, a heat exchange chamber 2 formed on the inner wall of the heat exchanger shell 1, and a plurality of heat exchange pipes 3 vertically and movably installed inside the heat exchange chamber 2. It should be noted that: the number of heat exchange pipes 3 is set to eight groups, each group of heat exchange pipes 3 consists of four horizontally distributed pipes, and the eight groups of heat exchange pipes 3 are equidistantly arranged along the circumference inside the heat exchanger shell 1.

[0018] It also includes: an adjustment mechanism 4 that is installed on the lower part of the heat exchanger shell 1 to drive the heat exchange tube 3 to move.

[0019] An exhaust mechanism 5 is installed inside the heat exchange tube 3 for gas flow guidance. An exhaust bracket 6, which mates with the top of the exhaust mechanism 5, is installed on the upper part of the heat exchanger shell 1. It should be noted that one end of the exhaust bracket 6 extends to the outside of the heat exchanger shell 1 and connects to the evaporator liquid recovery tank for recycling. This recycling method is existing technology and will not be described in detail.

[0020] In this embodiment, as Figures 1 to 10As shown, the adjustment mechanism 4 includes a drive chamber 401 located at the lower part of the heat exchanger housing 1, and a drain pipe 402 is vertically fixedly connected to the middle of the inner wall of the drive chamber 401. An impeller 403, which drives the heat exchange tube 3 to move upward, is rotatably mounted in the middle of the drain pipe 402. It should be noted that the outer edge of the impeller 403 is clearance-fitted with the inner wall of the drive chamber 401, the bottom of the heat exchange tube 3 extends into the drive chamber 401, and the blades of the rotating impeller 403 contact the bottom of the heat exchange tube 3, driving the heat exchange tube 3 to move upward inside the heat exchange chamber 2.

[0021] A partition plate 404 is fixedly installed in the middle of the heat exchange chamber 2. Heat exchange tubes 3 are vertically inserted through the surface of the partition plate 404. An adjusting spiral groove 405 is provided inside the partition plate 404. An adjusting pin 406, which slides in conjunction with the adjusting spiral groove 405, is fixedly connected to the surface of the heat exchange tubes 3. It should be noted that as the heat exchange tubes 3 move upwards inside the partition plate 404, the adjusting pin 406 slides along the trajectory of the adjusting spiral groove 405. The adjusting pin 406 causes the heat exchange tubes 3 to rotate inside the heat exchange chamber 2, disturbing the liquid inside the heat exchange chamber 2 and improving the heat exchange effect.

[0022] An inlet pipe 407 is eccentrically installed at the lower part of the heat exchanger shell 1 and communicates with the drive chamber 401. A U-shaped pipe 408 is fixedly connected to the middle of the heat exchanger shell 1, connecting the drive chamber 401 and the heat exchange chamber 2. A drain pipe 409, communicating with the heat exchange chamber 2, is fixedly connected to the upper part of the side wall of the heat exchanger shell 1. It should be noted that: the liquid after heat exchange in the data center is pumped from the eccentrically installed inlet pipe 407 to the inside of the drive chamber 401. Under the action of water pressure, the impeller 403 is driven to rotate, and the rotating impeller 403 drives the liquid to enter the heat exchange chamber 2 from the U-shaped pipe 408 for heat exchange treatment.

[0023] In this embodiment, as Figures 1 to 10 As shown, the heat exchange chamber 2 has insertion holes 410 at its top and bottom, respectively. The two ends of the heat exchange tube 3 are inserted into the two insertion holes 410, and each end of the heat exchange tube 3 is fixedly connected to a gasket 411. The two gaskets 411 are slidably disposed inside the two insertion holes 410, and a compression spring 412 is fixedly connected between the inner wall of the insertion hole 410 and the surface of the gasket 411. It should be noted that when the blades of the impeller 403 release their pressure on the bottom of the heat exchange tube 3, the compression spring 412 drives the gasket 411 and the heat exchange tube 3 to move downwards, causing the heat exchange tube 3 to move into the drive chamber 401 to its initial position.

[0024] A telescopic bellows 413 is fixedly connected to the side wall of the lower gasket 411. The lower end of the telescopic bellows 413 extends into the interior of the heat exchange tube 3. A drain support 414 is fixedly connected to the lower part of the inner wall of the heat exchanger shell 1. The middle part of the drain support 414 is fixedly connected to the surface of the drain pipe 402, and the upper end of the telescopic bellows 413 is fixedly connected to the surface of the drain support 414. It should be noted that the excess evaporating liquid that is not completely evaporated in the heat exchange tube 3 can flow into the drain support 414 through the telescopic bellows 413 and be discharged outward through the drain pipe 402 for recycling. The lower gasket 411 is fixedly installed at the lower position of the heat exchange tube 3 by a sealed bearing to ensure that the telescopic bellows 413 and the lower gasket 411 are not affected by the rotation of the heat exchange tube 3. The setting of the telescopic bellows 413 can avoid interference with the vertical movement of the heat exchange tube 3.

[0025] In this embodiment, as Figures 1 to 10 As shown, a buffer bellows 415 is fixedly connected to the top of the heat exchange tube 3, and a liquid delivery cone sleeve 416 is mounted on the top of the buffer bellows 415 via a bearing. The liquid delivery cone sleeve 416 is fixedly installed on the top of the heat exchanger shell 1. It should be noted that the evaporating liquid for heat exchange enters the liquid delivery cone sleeve 416 from the top of the heat exchanger shell 1, and is guided by the liquid delivery cone sleeve 416 to guide the evaporating liquid into the heat exchange tube 3 for heat exchange treatment. The buffer bellows 415 is provided to avoid interference with the vertical movement of the heat exchange tube 3, ensuring that the evaporating liquid inside the liquid delivery cone sleeve 416 stably enters the heat exchange tube 3.

[0026] The bottom of the heat exchange tube 3 is designed as an arc surface, and the top surface of the blades of the impeller 403 has an inclined surface that matches the bottom of the heat exchange tube 3. The middle part of the heat exchange tube 3 is spiral-shaped. It should be noted that the inclined surface of the blades of the impeller 403 matches the arc surface at the bottom of the heat exchange tube 3, which facilitates the rotation of the impeller 403 to drive the heat exchange tube 3 upward; the spiral shape of the heat exchange tube 3 increases the heat exchange area.

[0027] In this embodiment, as Figures 1 to 10 As shown, a circular hole 417 for installing the heat exchange tube 3 is provided in the middle of the partition 404. An adjusting spiral groove 405 is formed on the inner wall of the circular hole 417, and the end of the adjusting pin 406 near the inner wall of the adjusting spiral groove 405 is spherical. It should be noted that: under the action of the partition 404, the heat exchange chamber 2 is divided into two chambers, which are connected by a U-shaped tube 408 to guide the liquid flow. Two or three partitions 404 can be set to realize multi-layer fluid stratified heat exchange and improve the heat exchange and cooling effect.

[0028] In this embodiment, as Figures 1 to 10As shown, the exhaust mechanism 5 includes a flow-guiding spiral groove 501 formed on the inner wall of the heat exchange tube 3, and an exhaust pipe 502 is vertically fixedly connected to the middle of the inner wall of the heat exchange tube 3. It should be noted that a flow-guiding gap is reserved between the outer wall of the exhaust pipe 502 and the inner wall of the heat exchange tube 3 to allow the evaporating liquid to flow, and the flow-guiding spiral groove 501 is spirally engaged with the middle of the heat exchange tube 3, allowing the evaporating liquid to enter the interior of the spiral structure, further improving the heat exchange effect.

[0029] A guide hole 503 is obliquely opened on the surface of the exhaust pipe 502. A spiral guide plate 504 that cooperates with the guide spiral groove 501 is fixedly connected to the surface of the exhaust pipe 502. A telescopic pipe 505 is rotatably connected to the top of the exhaust pipe 502, and the upper part of the telescopic pipe 505 is fixedly connected to the surface of the exhaust support 6. It should be noted that: a number of guide holes 503 are equidistantly arranged on the surface of the exhaust pipe 502 along the circumference. The air inlet end of the guide hole 503 is chamfered to facilitate the entry of the evaporated gas into the exhaust pipe 502 and its upward discharge. The guide holes 503 are obliquely opened upward to reduce the amount of evaporated liquid entering the exhaust pipe 502. A drain hole is opened at the bottom of the exhaust pipe 502 to discharge excess evaporated liquid inside the exhaust pipe 502. The spiral guide plate 504 is offset from the guide hole 503.

[0030] In this embodiment, as Figures 1 to 10 As shown, the lower part of the telescopic tube 505 is movably connected to the top of the exhaust tube 502 via a connecting bearing, and the top of the telescopic tube 505 extends through the infusion cone sleeve 416 to the exhaust bracket 6 at the top of the heat exchanger housing 1. It should be noted that the connecting bearing and the telescopic tube 505 are designed to prevent interference with the exhaust tube 502 as it rotates and moves up and down with the heat exchange tube 3.

[0031] In this embodiment, as Figures 1 to 10 As shown, the top of the heat exchanger shell 1, located at the liquid delivery cone sleeve 416, is designated as the evaporator liquid delivery chamber 7, and the bottom of the heat exchanger shell 1, located at the lower end of the drain pipe 402, is designated as the evaporator liquid discharge chamber 8. It should be noted that the evaporator liquid enters the liquid delivery cone sleeve 416 from the evaporator liquid delivery chamber 7, while excess evaporator liquid inside the heat exchange tube 3 enters the evaporator liquid discharge chamber 8 from the drain pipe 402.

[0032] The method of use and advantages of this invention: The working process of this data center heat pipe heat exchange structure is as follows: like Figures 1 to 10As shown, during use, the heat-carrying liquid after heat exchange in the data center is pumped into the heat exchanger shell 1 through the water inlet pipe 407. Simultaneously, the evaporator liquid is transported to the liquid delivery cone sleeve 416 through the evaporator liquid delivery chamber 7 at the top of the heat exchanger shell 1, and introduced into the inner cavity of the corresponding heat exchange tube 3. Relying on the phase change heat absorption of the evaporator liquid in the heat exchange tube 3, the heat-carrying liquid on the outside of the tube is cooled. The cooled heat-carrying liquid is finally output through the drain pipe 409 and flows back to the data center for circulating heat dissipation. During this process, the heat-carrying liquid first flows into the drive chamber 401 of the heat exchanger shell 1. The fluid flow potential energy drives the impeller 403 to rotate circumferentially around the outer wall of the drain pipe 402. The blades of the rotating impeller 403 intermittently press and push against the bottom of each heat exchange tube 3, causing the heat exchange tube 3 to move upward. At the same time, the impeller 403 drives the heat-carrying liquid in the drive chamber 401 to be transported to the U-shaped tube 408, and then guided by the U-shaped tube 408 into the heat exchange chamber 2 for heat exchange treatment. When the heat exchange tube 3 moves upward between the heat exchange chamber 2 and the partition 404, the adjusting pin 406 fixed in the middle of the heat exchange tube 3 slides along the trajectory of the adjusting spiral groove 405 opened on the inner wall of the partition 404, so that the heat exchange tube 3 rotates circumferentially at the same time as it is vertically raised. Since the outer wall of the heat exchange tube 3 is provided with a spiral part, the rotation of the heat exchange tube 3 causes multi-dimensional disturbance to the heat-carrying liquid surrounding the spiral part. The outer wall of the exhaust pipe 502 is equipped with a spiral guide plate 504, which guides and constrains the evaporating liquid moving downward in the inner cavity of the heat exchange tube 3, forcing the evaporating liquid to travel along the curve of the guide spiral groove 501, extending the flow path of the evaporating liquid and improving the heat exchange effect. Meanwhile, the small vibration effect formed by the reciprocating rise and fall of the heat exchange tube 3 can break the phenomenon of steam sticking to the wall and stagnating generated by the evaporation phase change, ensuring that the gaseous working fluid rises quickly. The rising steam passes through the gas guide hole 503 inclinedly arranged on the wall of the exhaust pipe 502 and enters the inner cavity of the exhaust pipe 502. Then it is discharged from the exhaust support 6 through the telescopic pipe 505 and sent to the downstream equipment for condensation and liquefaction for reuse. The excess liquid evaporator in the heat exchange tube 3 that has not been completely vaporized is discharged from the bottom of the drain pipe 402 and connected to the pipeline for return circulation. Finally, the heat transfer liquid, after sufficient heat exchange and cooling, is discharged from the drain pipe 409 at the top of the heat exchanger shell 1. The heat transfer liquid is arranged with the bottom inlet and the top outlet. The flow direction is cross-coupled with the vertical reciprocating motion trajectory of the heat exchange tube 3 and the downward transported evaporator. The circumferential rotation of the heat exchange tube 3 is superimposed to continuously flush and peel off the liquid thermal boundary layer that is closely attached to the outer wall of the heat exchange tube 3, further enhancing the overall heat exchange efficiency.
