Description

Technical Field

[0001] This invention relates to the field of cooling device technology, specifically to an integrated cooling device for cooling air and purified water. Background Technology

[0002] In industrial production, data centers and other fields, air and water cooling are both key processes to ensure the stable operation of the system. The integration of their functions is an important development direction for the industry to meet the needs of energy conservation, emission reduction and space optimization. As the core heat exchange component of the cooling system, tubular heat exchangers are widely used in air and water cooling scenarios due to their advantages of high heat exchange efficiency, stable structure and wide range of compatible media.

[0003] However, existing tubular heat exchangers have inherent structural limitations that severely restrict the improvement of heat exchange efficiency. Their heat exchange tubes mostly adopt a straight-through or simple bend-type flow channel design without built-in turbulence structure. This results in air or liquid flowing smoothly along the axis of the tube cavity when flowing inside the tube, and the fluid state is mostly laminar. This flow mode makes it easy to form a thick heat transfer boundary layer between the medium and the inner wall of the heat exchange tube. Heat can only be transferred through slow heat conduction, and temperature gradient dead zones are easy to appear in the fluid inside the tube. The effective heat transfer area of ​​the heat exchange tube cannot be fully utilized, resulting in low heat exchange efficiency.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

The adjusting ring has multiple adjusting ports, each with a variable diameter structure, one end larger than the other. The heat exchange tube has a flow exchange hole, and the adjusting ports and flow exchange holes are connected to each other. The rotating sleeve is equipped with a piston plate that can slide along its axial direction. An electromagnet is provided on one side of the piston plate. A permanent magnet ring is installed inside the rotating sleeve, facing the electromagnet. When the electromagnet is energized, it repels the permanent magnet ring magnetically.

[0007] Furthermore, the outer wall of the rotating sleeve is provided with a plurality of heat exchange fins, which are equidistantly distributed along the circumference of the rotating sleeve. The inner wall of the rotating sleeve is also provided with a spiral groove. The outer wall of the piston plate is provided with a transmission head extending radially therefrom, which extends into the interior of the spiral groove. When the piston plate slides along the axial direction of the heat exchange tube, the transmission head slides along the inner wall of the spiral groove to drive the rotating sleeve to rotate around its own axis.

[0008] Furthermore, the transmission head is made of conductive material and is electrically connected to the electronic control terminal of the electromagnet. A power supply contact is provided on the inner wall of the spiral groove near the permanent magnet ring. When the transmission head contacts the power supply contact, the electromagnet is electrically conductive.

[0009] Furthermore, the inner ring of the piston plate is sealed to the outside of the heat exchange tube, and a guide groove extending axially is provided on the outer wall of the heat exchange tube. A guide block is slidably installed inside the guide groove, and the guide block is fixed to the inner wall of the piston plate.

[0010] Furthermore, a metal plate corresponding to the position of the exchange hole is installed on the inner wall of the heat exchange tube. One end of the metal plate is fixed to the inner wall of the heat exchange tube, and the other end extends at an angle.

[0011] Furthermore, an anti-backflow plate is provided at the inlet end of the heat exchange tube. The anti-backflow plate has multiple through holes, and a metal sheet is also installed on the right side of the anti-backflow plate, which covers the outside of the through holes.

[0012] Furthermore, the integrated shell includes a tubular shell, which is a hollow circular tube structure with tube plates installed at both ends for fixing heat exchange tubes. A front cover is installed at the left end of the tubular shell, and a rear cover is installed at the right end. An air inlet pipe and a water inlet pipe are provided on the front cover, connecting the air heat exchange chamber and the clean water heat exchange chamber. An air outlet pipe and a water outlet pipe are provided on the rear cover, connecting the air heat exchange chamber and the clean water heat exchange chamber. A cold medium inlet pipe and a cold medium outlet pipe, which communicate with the interior, are installed on the outer wall of the tubular shell.

[0013] Furthermore, the air heat exchange chamber includes an air inlet chamber and an air outlet chamber, the water heat exchange chamber includes a water inlet chamber and a water outlet chamber, a front partition is provided inside the front cover, the front partition is sealed and fitted with the front cover to block heat transfer between the water inlet chamber and the air inlet chamber, and a rear partition is provided inside the rear cover, the rear partition is sealed and fitted with the rear cover to block heat transfer between the water outlet chamber and the air outlet chamber.

[0014] Furthermore, the interior of the tubular shell is equipped with several baffles, which are arranged in an alternating pattern, and the heat exchange tubes are inserted through the baffles.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes the pressure of the medium within the heat exchange tube to precisely drive a piston plate, which is sealed and fitted to the heat exchange tube, to move axially along a guide groove. Power transmission is achieved through the structural cooperation of a transmission head and a spiral groove. Combined with the instantaneous magnetic repulsion generated by an electromagnet and a permanent magnet ring, the medium inside the rotating sleeve is rapidly squeezed and flows back at high speed through the exchange holes and variable diameter adjustment ports, forming a powerful jet. The jet impacts the inclined metal plate on the inner wall of the heat exchange tube, creating secondary turbulence within the tube. Simultaneously, the axial movement of the piston plate, linked to the rotating sleeve via the transmission structure, drives the heat exchange fins to rotate, specifically disturbing the cold medium inside the tubular shell. The coordinated operation of these structures completely breaks the inherent limitation of the smooth flow of the medium inside the tube in traditional tubular heat exchangers. This interconnected structural design simultaneously enhances heat exchange in both the inner and outer dimensions of the tube, significantly improving heat transfer efficiency and the uniformity of medium heat exchange. It effectively solves the problem of insufficient heat exchange enhancement from a single turbulence structure. While ensuring independent cooling of both air and purified water media, it also considers the heat exchange effect and long-term operational stability of the device, perfectly meeting the actual needs of integrated dual-media cooling.

[0016] 2. In this invention, the axial sliding of the piston plate is converted into the rotation of the rotating sleeve around its axis through the cooperation of the transmission head and the spiral groove. This rotation drives the heat exchange fins, which are circumferentially equidistantly distributed on its outer wall, to rotate synchronously. This specifically disturbs the cold medium inside the tubular shell, disrupts the heat transfer boundary layer between the cold medium and the outer wall of the heat exchange tube, and enhances heat transfer outside the tube. In addition, the inclined metal plates installed on the inner wall of the heat exchange tube corresponding to the exchange holes are impacted by the jet and vibrate, further disrupting the trajectory of the medium inside the tube, forming secondary turbulence, eliminating temperature dead zones, and making full use of the heat exchange area.

[0019] 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.

[0020] Please see Figures 1-8 The present invention provides a technical solution: an integrated cooling device for air and purified water cooling, comprising: An integrated housing, with an internally isolated air heat exchange chamber and a purified water heat exchange chamber; The tubular heat exchanger assembly passes through the air heat exchange chamber and the clean water heat exchange chamber and is sealed and fixed to the integrated shell. The tubular heat exchanger assembly includes several heat exchange tubes 17, and each heat exchange tube 17 is provided with a turbulence structure. The turbulence structure includes a rotating sleeve 18 and an adjusting ring 20 rotatably connected to the outer wall of the heat exchange tube 17. The adjusting ring 20 has multiple adjusting ports 21, each with a variable diameter structure that is larger at one end and smaller at the other. The heat exchange tube 17 has a flow exchange hole 25, and the adjusting port 21 and the flow exchange hole 25 are connected to each other. The rotating sleeve 18 is provided with a piston plate 27 that can slide along its axial direction. An electromagnet 30 is provided on one side of the piston plate 27. A permanent magnet ring 31 is installed inside the rotating sleeve 18, which is directly opposite to the electromagnet 30. When the electromagnet 30 is energized, it repels the permanent magnet ring 31 magnetically.

[0021] Specifically, the integrated shell has separate air heat exchange chambers and water heat exchange chambers to achieve physical isolation and synchronous operation of dual-medium cooling. The tubular heat exchange component 17 runs through the two chambers and is sealed and fixed to the shell. As the core carrier for heat exchange, the turbulence structure on each heat exchange tube 17 achieves turbulence through mechanical linkage and electromagnetic drive: the medium in the heat exchange tube 17 flows into the rotating sleeve 18 through the exchange hole 25 and the variable diameter adjustment port 21 of the adjustment ring 20, pushing the piston plate 27 to slide towards the permanent magnet ring 31. After the transmission head 29 contacts the power supply contact 32, the electromagnet 30 is energized and generates an instantaneous magnetic repulsion force with the permanent magnet ring 31, pushing the piston plate 27 to slide in the opposite direction, squeezing the medium to flow back at high speed from the exchange hole 25 and the adjustment port 21 to form a jet, while driving the rotating sleeve 18 to rotate, breaking the stable flow state inside the tube.

[0022] The integrated design of dual heat exchange chambers eliminates the need for independent cooling equipment, significantly reducing space occupation and pipeline costs, making it suitable for space-constrained scenarios. Through jet effect and rotation linkage, the heat transfer boundary layer is broken and temperature dead zones are eliminated, resulting in a significant improvement in heat exchange efficiency compared to traditional steady flow. The variable diameter regulating port 21 adapts to different medium flow velocities, taking into account the heat exchange needs of air and clean water, avoiding the problem of poor single-medium adaptability, and improving the versatility of the device.

[0023] As a technical optimization of the present invention, a plurality of heat exchange fins 19 are provided on the outer wall of the rotating sleeve 18. The plurality of heat exchange fins 19 are distributed equidistantly along the circumference of the rotating sleeve 18. A spiral groove 28 is also provided on the inner wall of the rotating sleeve 18. A transmission head 29 extending radially is provided on the outer wall of the piston plate 27. The transmission head 29 extends into the interior of the spiral groove 28. When the piston plate 27 slides along the axial direction of the heat exchange tube 17, the transmission head 29 slides along the inner wall of the spiral groove 28 to drive the rotating sleeve 18 to rotate around its own axis.

[0024] Specifically, the heat exchange fins 19 on the outer wall of the rotating sleeve 18 are equidistantly distributed along the circumference and rotate synchronously with the rotating sleeve 18; the spiral groove 28 on the inner wall of the rotating sleeve 18 cooperates with the transmission head 29 of the piston plate 27 to convert the axial sliding of the piston plate 27 into the rotation of the rotating sleeve 18 around the axis, realizing the efficient conversion of axial power and rotational motion; when the heat exchange fins 19 rotate, they specifically disturb the cooling medium inside the tubular shell 1 to enhance the heat exchange outside the tube.

[0025] The rotating fins disturb the cooling medium, which, in conjunction with the flow channel guidance of the baffle 16 in the background technology, further improves the contact between the cooling medium and the outer wall of the heat exchange tube 17, solving the bottleneck problem of external heat exchange; no additional driving device is required, and linkage is achieved by relying on the medium thrust and electromagnetic repulsion; the transmission structure is integrated inside the rotating sleeve 18, avoiding the problem of redundant structure of integrated equipment and improving operational stability.

[0026] As a technical optimization of the present invention, the transmission head 29 is made of conductive material and is electrically connected to the control terminal of the electromagnet 30. A power supply contact 32 is provided on the inner wall of the spiral groove 28 near the permanent magnet ring 31. When the transmission head 29 contacts the power supply contact 32, the electromagnet 30 is electrically conductive.

[0027] Specifically, the conductive transmission head 29 is electrically connected to the control terminal of the electromagnet 30. The power supply contact 32 on the inner wall of the spiral groove 28 only contacts the transmission head 29 when the piston plate 27 slides to a position close to the permanent magnet ring 31, so that the electromagnet 30 is energized to generate a repulsive force, thereby realizing the precise triggering and instantaneous action of electromagnetic drive.

[0028] It requires no manual adjustment and automatically triggers electromagnetic repulsion based on the flow state of the medium, solving the problem of cumbersome adjustment in distributed systems and reducing operating costs; it is powered only when reverse push is needed, resulting in lower energy consumption than continuous power supply mode, which meets the requirements of energy conservation and emission reduction.

[0029] As a technical optimization of the present invention, the inner ring of the piston plate 27 is sealed and fitted to the outside of the heat exchange tube 17. A guide groove 33 extending along its axial direction is provided on the outer wall of the heat exchange tube 17. A guide block 34 is slidably installed inside the guide groove 33. The guide block 34 is fixed to the inner wall of the piston plate 27.

[0030] Specifically, the inner ring of the piston plate 27 is sealed to the outer wall of the heat exchange tube 17 to prevent medium leakage; the guide groove 33 on the outer wall of the heat exchange tube 17 is slidably engaged with the guide block 34 on the inner wall of the piston plate 27 to restrict the piston plate 27 to move only along the axial direction and avoid circumferential displacement that could lead to transmission failure.

[0031] The sealed design prevents media leakage and ensures the independence of air and clean water cooling; the guiding structure improves motion accuracy, ensures that the transmission head 29 is stably embedded in the spiral groove 28, avoids linkage failure, reduces maintenance frequency, and is suitable for long-term continuous operation.

[0032] As a technical optimization of the present invention, a metal plate 26 corresponding to the position of the exchange hole 25 is installed on the inner wall of the heat exchange tube 17. One end of the metal plate 26 is fixed to the inner wall of the heat exchange tube 17, and the other end extends obliquely.

[0033] Specifically, the metal plate 26 on the inner wall of the heat exchange tube 17 corresponds to the position of the exchange hole 25, with one end fixed and the other end extending at an angle. When the jet medium flows back from the exchange hole 25, the inclined metal plate 26 further disrupts the flow trajectory of the medium and enhances the heat conduction around the exchange hole 25.

[0034] The jet action creates multiple disturbances, completely breaking the laminar flow state, solving the problem of temperature dead zones inside the tube, and making full use of the effective heat transfer area of ​​the heat exchange tube 17; the metal plate 26 accelerates the transfer of heat from the medium inside the tube to the tube wall, improving the heat exchange rate and further improving the heat transfer efficiency compared with traditional tubular heat exchangers.

[0035] As a technical optimization of the present invention, an anti-backflow plate 22 is provided at the inlet end of the heat exchange tube 17. The anti-backflow plate 22 has multiple through holes 23. A metal sheet 24 is also installed on the right side of the anti-backflow plate 22, and the metal sheet 24 blocks the outside of the through holes 23.

[0036] Specifically, the anti-backflow plate 22 at the inlet end of the heat exchange tube 17 guides the medium to enter the tube evenly through the through hole 23. The metal plate 24 on the right side blocks the outside of the through hole 23. When the medium shows a backflow tendency, the metal plate 24 tightly fits the through hole 23 to block the backflow channel.

[0037] To avoid heat exchange efficiency fluctuations caused by medium backflow, solve the problem of unstable medium flow affecting cooling effect, and ensure cooling accuracy; uniform flow guidance ensures that the medium fully covers the inner cross section of the pipe, avoids local medium accumulation, further eliminates temperature gradient, and improves heat exchange uniformity.

[0038] As a technical optimization of the present invention, the integrated shell includes a tubular shell 1, which is a hollow circular tube structure with tube plates installed at both ends for fixing heat exchange tubes 17. A front cover 2 is installed at the left end of the tubular shell 1, and a rear cover 3 is installed at the right end. An air inlet pipe 7 and a water inlet pipe 8 are provided on the front cover 2 to connect the air heat exchange chamber and the clean water heat exchange chamber. An air outlet pipe 12 and a water outlet pipe 13 are provided on the rear cover 3 to connect the air heat exchange chamber and the clean water heat exchange chamber. A cold medium inlet pipe 14 and a cold medium outlet pipe 15 communicating with the interior are installed on the outer wall of the tubular shell 1.

[0039] Specifically, the tubular shell 1 is a hollow circular tube structure, with heat exchange tubes 17 fixed at both ends of the tube sheet. The front cover 2 and the rear cover 3 are respectively provided with an air inlet pipe 7, a water inlet pipe 8, an air outlet pipe 12, and a water outlet pipe 13 to realize independent entry and exit of dual media. The cold medium inlet pipe 14 and the cold medium outlet pipe 15 are connected to the inside of the tubular shell 1 to form a cold medium circulation channel.

[0040] The integrated shell design combines a dual cooling system with a cold media circulation system, replacing decentralized equipment and significantly reducing installation space and construction costs; the independent inlet and outlet design ensures clear media flow separation, avoids mutual interference, and facilitates inspection and maintenance.

[0041] As a technical optimization of the present invention, the air heat exchange chamber includes an air inlet chamber 6 and an air outlet chamber 11, the water heat exchange chamber includes a water inlet chamber 5 and a water outlet chamber 10, a front partition 4 is provided inside the front cover 2, the front partition 4 is sealed and fitted with the front cover 2 to block the heat transfer between the water inlet chamber 5 and the air inlet chamber 6, and a rear partition 9 is provided inside the rear cover 3, the rear partition 9 is sealed and fitted with the rear cover 3 to block the heat transfer between the water outlet chamber 10 and the air outlet chamber 11.

[0042] Specifically, the front partition 4 in the front cover 2 and the rear partition 9 in the rear cover 3 are sealed and fitted to the cover, completely isolating the air inlet chamber 6 and air outlet chamber 11 of the air heat exchange chamber from the water inlet chamber 5 and water outlet chamber 10 of the clean water heat exchange chamber, thus blocking heat crosstalk between the two chambers.

[0043] It ensures that air and purified water can be precisely temperature controlled according to their respective needs, improving cooling accuracy; the sealed and heat-insulating design reduces heat loss and lowers the energy consumption of the cooling medium, meeting energy-saving requirements, while preventing high-temperature media from affecting the cooling effect of low-temperature media.

[0044] As a technical optimization of the present invention, a number of baffles 16 are also installed inside the tubular shell 1. The baffles 16 are arranged in an alternating manner, and the heat exchange tubes 17 are inserted through the baffles 16.

[0045] Specifically, the baffles 16 inside the tubular shell 1 are arranged alternately, and the heat exchange tubes 17 are inserted through the baffles 16. The refrigerant is guided by the baffles 16 to form a tortuous flow channel, which prolongs the contact time with the outer wall of the heat exchange tubes 17.

[0046] The rotation of the heat exchange fins 19 further disrupts the heat transfer boundary layer of the cold medium, supporting and fixing the heat exchange tube 17: preventing the heat exchange tube 17 from deforming due to medium impact or vibration, improving the structural stability of the device, extending the heat exchange time, improving the utilization rate of the cold medium, and reducing the energy consumption of cold medium circulation.

[0047] The core of this device separates independent heat exchange chambers through an integrated shell. It relies on tubular heat exchange components 17 with turbulence-inducing structures to achieve simultaneous and efficient cooling of air and purified water. At the same time, it enhances the heat exchange effect through the circulation of a cold medium. All structures work together to form a complete cooling system. The specific working principle is as follows: The device uses a tubular shell 1 as its core integrated shell body. Tube sheets at both ends are used to fix several heat exchange tubes 17. The left front cover 2 and the right rear cover 3 are separated by a front partition 4 and a rear partition 9, respectively, into an independent air heat exchange chamber (inlet chamber 6, outlet chamber 11) and a clean water heat exchange chamber (inlet chamber 5, outlet chamber 10). The partitions are designed to seal and fit tightly, preventing heat crosstalk between the two chambers and ensuring independent cooling. During operation, the air to be cooled enters the inlet chamber 6 through the inlet pipe 7 of the front cover 2, and the clean water to be cooled enters the inlet chamber 5 through the inlet pipe 8. The refrigerant is injected into the shell cavity through the refrigerant inlet pipe 14 on the outer wall of the tubular shell 1, and guided by staggered baffles 16 to form a tortuous flow channel, fully covering the outer wall of the heat exchange tubes 17, and finally discharged from the refrigerant outlet pipe 15. The cooled air and clean water are output through the outlet pipe 12 and outlet pipe 13 of the rear cover 3, respectively, achieving split cooling and recovery.

[0048] The turbulence structure on each heat exchange tube 17 is the core of enhanced heat exchange. Its operation is driven by the thrust of the medium, combined with the instantaneous electromagnetic repulsion to achieve coordinated turbulence. The inner ring of the piston plate 27 is sealed to the outer wall of the heat exchange tube 17 and slides axially along the guide groove 33 of the heat exchange tube 17 via the guide block 34, ensuring precise movement. During operation, the clean water or air inside the heat exchange tube 17 first flows into the rotating sleeve 18 through the exchange hole 25 and the variable diameter adjustment port 21 on the adjustment ring 20. With the pressure of the medium itself, the piston plate 27 slides axially toward the permanent magnet ring 31. When the conductive material of the transmission head 29 on the outer wall of the piston plate 27 slides close to the permanent magnet ring 31 and contacts the power supply contact 32 on the spiral groove 28 on the inner wall of the rotating sleeve 18, the electromagnet 30 is electrically connected to the electrical control terminal of the transmission head 29 and energized, generating a magnetic repulsion force with the permanent magnet ring 31 inside the rotating sleeve 18. This repulsion force is an instantaneous thrust, pushing the piston plate 27 rapidly away from the permanent magnet ring 31 axially. During this process, the clean water or air inside the rotating sleeve 18 is rapidly squeezed by the piston plate 27 and flows back at high speed from the exchange hole 25 and the variable diameter adjustment port 21 to the inside of the heat exchange tube 17, forming a strong jet effect that violently turbulently disturbs the medium flowing smoothly inside the heat exchange tube 17. At the same time, the transmission head 29 slides along the spiral groove 28, converting the axial movement of the piston plate 27 into the rotation of the rotating sleeve 18 around the axis, which drives the heat exchange fins 19 circumferentially distributed on its outer wall to rotate synchronously, specifically disturbing the cold medium inside the tubular shell 1, destroying the heat transfer boundary layer between the cold medium and the outer wall of the heat exchange tube 17, and further improving the heat exchange efficiency outside the tube.

[0049] When the rotating sleeve 18 rotates, the adjusting ring 20 on its inner wall rotates synchronously, so that the variable diameter adjusting port 21 on the adjusting ring 20 is larger at one end and smaller at the other end, dynamically corresponding and connecting with the exchange hole 25 of the heat exchange tube 17. The medium can achieve a small amount of exchange between the inside and outside of the tube through the variable diameter adjusting port 21 and the exchange hole 25. At the same time, the variable diameter structure causes a sudden change in the medium flow velocity, forming local turbulence inside the tube. In conjunction with the inclined metal plate 26 installed on the inner wall of the heat exchange tube 17 corresponding to the exchange hole 25, the flow trajectory of the medium inside the tube is further disrupted, temperature dead zones are eliminated, and the effective heat transfer area of ​​the heat exchange tube 17 is fully utilized.

[0050] The supporting structure of the device further enhances the operational stability and heat exchange effect: the anti-backflow plate 22 at the inlet end of the heat exchange tube 17 guides the medium to enter the tube evenly through the through hole 23, and the metal plate 24 on its right side blocks the outside of the through hole 23 to prevent the medium from flowing back and avoid fluctuations in cooling efficiency; in addition to the turbulence effect, the inclined metal plate 26 can also enhance the heat conduction around the exchange hole 25, accelerate the transfer of heat from the medium in the tube to the tube wall, and synergistically improve the overall heat exchange performance.

[0051] Guided by the baffle 16, the cold medium fully contacts the outer wall of the heat exchange tube 17, achieving heat exchange with the medium inside the tube through the tube wall. The turbulence structure simultaneously achieves turbulence from the rotating fins outside the tube and turbulence from the variable diameter inside the tube, significantly improving the heat transfer rate between the inside and outside of the tube. The independent heat exchange chamber and sealed design ensure that air and clean water cooling do not interfere with each other. The baffle 16 not only enhances the turbulence of the cold medium but also provides support and fixation for the heat exchange tube 17. The coordinated operation of these structures forms a complete workflow of cold medium circulation cooling, enhanced turbulence inside and outside the tube, and independent output of the two media, significantly improving the efficiency and stability of integrated cooling.
