Description

Technical Field

[0001] This invention belongs to the field of computing server cooling, and specifically relates to a partitioned immersion phase change liquid cooling heat exchange system and a circulating heat exchange method for computing servers. Background Technology

[0002] Phase change cooling is a cooling technology that uses the process of liquid evaporation or solid melting and sublimation to absorb heat. In the existing immersion phase change liquid cooling solutions for high-density computing servers, whether it is an open or closed system, almost without exception, a single-tank integrated immersion layout is adopted: that is, all electronic components such as server motherboard, CPU, GPU, memory, power module, storage device and even cables are immersed together in the same sealed cavity filled with insulating coolant.

[0003] This seemingly simple and straightforward layout, in actual operation, exposed four core systemic flaws that severely limited its reliability, maintainability, and energy efficiency limits: the integrated slot became a thermodynamic "bathhouse," and high-power chips (>100W / cm²) were exposed to these flaws. 2 The chip requires intense nucleo-boiling to dissipate heat. To ensure chip cooling, the overall liquid temperature is maintained at a high level. This causes some temperature-sensitive low-power electronic components (such as certain capacitors and crystal oscillators) to be immersed in high temperatures for a long time, accelerating the aging and failure of components and reducing the reliability of the server throughout its entire life cycle. Moreover, a computing server contains hundreds or thousands of organic materials, including plastic cables, rubber seals, thermal grease and various PCB substrates. Immersing them all in the same chemical working fluid places extremely stringent and even contradictory requirements on the inertness, solubility and compatibility of the working fluid. Problems such as plasticizer precipitation, polymer swelling and metal corrosion caused by long-term immersion not only contaminate the expensive working fluid, but may also cause circuit failure. This constitutes a huge technical barrier to material compatibility.

[0004] In conclusion, there is an urgent need to propose a new structure to solve the aforementioned technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a partitioned immersion phase change liquid cooling heat exchange system and a circulating heat exchange method for computing servers, thereby solving the problems mentioned in the background art.

[0006] This invention is achieved through the following technical solution: a partitioned immersion phase change liquid cooling heat exchange system and circulating heat exchange method for a computing server, comprising: a server placement component, a condensation component, an insulating and sealing connection component one, an insulating and sealing connection component two, and a one-way valve group. The server placement component includes a liquid cooling box, a heat insulation partition, a high-power boiling zone, a medium-power boiling zone, and an auxiliary drying air cooling box. The heat insulation partition is fixedly installed in the middle of the inner side of the liquid cooling box. The high power consumption boiling zone is located in the left side of the heat insulation partition, the medium power consumption boiling zone is located in the right side of the heat insulation partition, and the auxiliary drying air cooling box is located in front of the liquid cooling box. The condensation assembly is located above the liquid cooling box, the first thermal insulation sealing connection assembly is installed on the rear side of the liquid cooling box, the second thermal insulation sealing connection assembly is installed on the front side of the liquid cooling box and located on the rear side of the auxiliary drying air cooling box, and the one-way valve group is installed on the lower inner side of the thermal insulation partition. The condensation assembly is used to condense the steam generated in the high-power boiling zone and the medium-power boiling zone into condensate, and to guide the condensate to the medium-power boiling zone. The one-way valve group is used to form a one-way liquid replenishment channel from the medium-power boiling zone to the high-power boiling zone between the medium-power boiling zone and the high-power boiling zone.

[0007] In a preferred embodiment, the auxiliary drying air-cooled box is filled with dry nitrogen and the coolant is circulated through a spiral tube built into the outer wall to achieve cooling and heat exchange. The spiral tube has an inlet end and an outlet end and is connected to an external coolant circulation pipeline. The condensation assembly includes a top seat, a lower steam guide plate, an upper condensate receiving plate, steam through holes, V-shaped microchannels, micro-slits, and a condenser. The lower steam guide plate is located inside the top seat, the upper condensate receiving plate is located above the lower steam guide plate, and the condenser is located at the upper end of the inner side of the top seat. Both the lower steam guide plate and the upper condensate receiving plate are inclined structures with the left side higher than the right side. Several steam through holes are formed through the lower surface of the lower steam guide plate and are linearly and equally distributed in the front, back, left and right directions. The V-shaped microchannels are formed on the upper surface of the upper condensate receiving plate and are set along the left-high and right-low inclined structure of the upper condensate receiving plate. The micro-slits are located below the V-shaped microchannels, and the lower steam guide plate and the upper condensate receiving plate are both thin metal plates that are compatible with the coolant and have good hydrophilicity.

[0008] In a preferred embodiment, the steam through holes and V-shaped microchannels are arranged in an alternating structure in the front and back directions of the vertical structure, and the lower steam guide plate has a drainage groove in the area below the micro-slits. The drainage ditch is designed as an inverted trapezoid. Several sets of transverse branch ditches are spaced apart at the front and rear ends of the lower steam guide plate below the drainage ditch. The main drainage channel is opened on the inner side of the front and rear ends of the lower steam guide plate. The transverse branch ditches are connected to the main drainage channel. The several sets of transverse branch grooves are set to avoid the steam passage. The transverse branch grooves are set with a slightly inclined structure towards the main drain channel. The upper condensate receiving plate is provided with a venting groove above the steam passage. A liquid-blocking cap is fixedly connected above the upper condensate receiving plate at the venting groove position, so that the condensate dripping from above is blocked from falling into the venting groove. The lower steam guide plate is fixedly connected to the lower right side of both the front and rear sides with liquid drop pipes. The liquid drop pipes are set above the medium power boiling zone. The heat insulation plate is composed of a middle heat insulation core layer in the middle position and metal cladding layers on both sides. The heat insulation plate is higher than the highest liquid level and has a row of multiple through holes to connect the steam space of the high power boiling zone and the medium power boiling zone to balance the overall pressure, but liquid is not allowed to pass through. The upper part of the heat insulation partition is inclined, and its top surface is attached to the bottom surface of the lower steam guide plate.

[0009] After the coolant boils, it generates steam. The steam in the high-power boiling zone and the medium-power boiling zone rises and is condensed by the condensing components. During the rise, the steam is guided through the steam through-holes and enters the upper condenser area. After the condensate falls, it first collects in the V-shaped microchannel and then collects in the drop pipe along the conveying path, so that the condensate can enter the medium-power boiling zone.

[0010] In a preferred embodiment, the lower right side of the heat insulation partition has four sets of linearly and equally distributed connecting holes, and the one-way valve assembly is sealed and installed inside the connecting holes by a sealing ring and fixed by bolts. The one-way valve assembly includes a connecting flange, a valve seat cylinder, a valve seat, a valve core umbrella seat, a perfluoroether rubber diaphragm, and a limiting ring. The valve seat cylinder is fixedly disposed on the left side of the connecting flange, the valve seat is fixedly disposed on the inner side of the valve seat cylinder, and the valve core umbrella seat is disposed on the inner side of the valve seat. The perfluoroether rubber diaphragm is disposed around the valve core seat, and the limiting ring is disposed on the left side of the perfluoroether rubber diaphragm. When the liquid level of the condensate rises in the medium power boiling zone and a static pressure difference is formed at the connecting hole, the perfluoroether rubber diaphragm bends up to open the one-way liquid replenishment channel from the medium power boiling zone to the high power boiling zone. When the static pressure difference of the liquid column decreases to a level insufficient to open the perfluoroether rubber diaphragm, the perfluoroether rubber diaphragm resets and seals against the valve seat.

[0011] As coolant gradually accumulates in the medium-power boiling zone, it compresses the steam space above, causing the condensate level in the medium-power boiling zone to rise. This creates a static pressure difference at the connecting hole that is higher than that in the high-power boiling zone. This static pressure difference acts on the perfluoroether rubber diaphragm, causing the edge of the perfluoroether rubber diaphragm to lift up and open the one-way valve assembly. Then, under the pressure difference with the high-power boiling zone, the perfluoroether rubber diaphragm is driven to lift up, causing it to break the seal with the valve seat. This allows coolant in the medium-power boiling zone to flow into the high-power boiling zone through the opened gap, achieving continuous coolant replenishment between the two zones.

[0012] In a preferred embodiment, the thermally insulating and sealing connection assembly includes a connecting cylinder, an isolation cavity, a sealing seat, an optical fiber bundle, and a micro photoelectric conversion module, wherein the isolation cavity is located in the middle of the inner side of the connecting cylinder. The fiber bundle is located coaxially with the isolation cavity and inside the isolation cavity. The fiber bundle is made of thousands of single-mode optical fibers that are melted, drawn, and sliced, and is covered with high borosilicate glass. The two sets of micro photoelectric conversion modules are respectively located on both sides of the fiber bundle. The two sets of sealing seats are located at both ends of the isolation chamber. The sealing seats consist of a set of perfluoroether rubber O-rings and a set of metal C-shaped sealing rings to achieve the sealing of the isolation chamber. The isolation chamber is pre-pumped to achieve a constant vacuum.

[0013] In use, the photoelectric conversion signal connection between the high-power boiling zone and the medium-power boiling zone is achieved through the heat-insulating and sealing connection component. Because the heat-insulating and sealing connection component can block the bidirectional permeation of fluids in the two spaces and block heat conduction, it can still transmit high-speed electrical / optical signals.

[0014] As a preferred embodiment, the thermally insulating sealing connection assembly further includes a monitoring seat, a pneumatic chamber, a piston, a retaining spring, a piston rod, a sealing bellows, an external plate, a ratchet, and a ratchet seat. The monitoring base is fixedly installed on the outside of the connecting cylinder, the air pressure chamber is opened on the inside of the connecting cylinder and faces the monitoring base, the piston is movably installed on the inside of the air pressure chamber, the piston column is fixedly connected to the side of the piston near the monitoring base, and the retaining spring is sleeved to the outside of the piston column. The sealing bellows is fixedly installed at the outer end opening of the air pressure chamber, and the outer plate is fixedly connected to the other end of the sealing bellows. The sealing bellows is made of thin-walled stainless steel by hydraulic forming, and has good axial elasticity and absolute airtightness. The ratchet is fixedly installed on the outside of the outer plate. The ratchet seat is located in the inner cavity of the monitoring seat. A connecting column is fixedly connected to one end of the ratchet seat away from the axis of the monitoring seat. A connecting seat is fixedly connected to the outside of the connecting column. A return spring is sleeved on the outside of the connecting column. An indicator plate is fixedly connected to the upper end of the connecting seat. The indicator plate consists of two symmetrical structures, a green plate and a red plate. When the inside of the isolation chamber is intact, the green plate is exposed; when the seal inside the isolation chamber fails, the red plate is exposed. The ratchet and ratchet seat mesh with each other and can only move in one direction. An audible and visual alarm is also fixedly installed inside the monitoring base. The audible and visual alarm is electrically connected to an electrode plate via a cable at one end near the connecting cylinder. The outer plate is also fixedly connected to an electrode plate at the other end away from the connecting cylinder. A button battery is also provided inside the monitoring base. The two electrode plates, the audible and visual alarm, and the button battery are connected in series and are only non-contact between the two electrode plates. When the outer plate moves closer to the audible and visual alarm, the two electrode plates make contact to achieve circuit conduction.

[0015] The thermally insulated sealing connection assembly has an internal isolation chamber. The isolation chamber is pre-evacuated to achieve a constant vacuum. When the seal fails, the pressure inside the isolation chamber will increase. Under the pressure difference with the air pressure chamber, the piston will be pushed to move away from the connecting cylinder, and the outer plate will follow suit. This will cause the ratchet to engage with the ratchet seat area, blocking reverse movement. When the ratchet seat is engaged, it will drive the connecting seat to move, thereby causing the indicator plate to switch to red and remind the user that the seal has failed. In this state, the audible and visual alarm will also be triggered, activating its starting circuit to achieve an audible and visual alarm.

[0016] In a preferred embodiment, both ends of the connecting cylinder are fixedly connected to a low thermal conductivity insulating structure ring, which is made of zirconia toughened ceramic material. The second insulating sealing connection component is a three-way structure and is functionally set together with the insulating sealing connection component. Two connection holes are provided on both the front and rear sides of the liquid cooling box. A connection hole is also provided on the rear side of the auxiliary drying air cooling box. Sealing flanges are provided on the outer sides of the liquid cooling box and the auxiliary drying air cooling box at the coaxial position of the connection holes. The sealing ring is fixedly connected to the low thermal conductivity insulation structure ring by bolts. The connection hole on one side of the liquid cooling box is connected to the high-power boiling zone and the medium-power boiling zone respectively. The first heat-insulating sealing connection component is used to realize the photoelectric conversion signal connection between the high-power boiling zone and the medium-power boiling zone. The second heat-insulating sealing connection component is used to realize the photoelectric conversion signal connection between the high-power boiling zone, the medium-power boiling zone and the auxiliary drying air-cooled box. The second heat-insulating and sealing connection assembly includes a three-way connecting cylinder, three low thermal conductivity heat-insulating structural rings, three sealing seats, at least two sets of optical fiber bundles, and miniature photoelectric conversion modules respectively disposed at the three connection ends. The three connection ends correspond to the high-power boiling zone, the medium-power boiling zone, and the auxiliary drying air-cooled box, respectively. Each connection end of the three-way connecting cylinder is provided with an independent sealing seat to block fluid penetration between the corresponding zones. The optical fiber bundles are used to transmit optical signals between the three zones.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are: By configuring server placement components, condensation components, and one-way valve groups, and based on the power consumption of different electronic components in the computing server, high, medium, and low power electronic components are integrated and partitioned into high-power boiling zones, medium-power boiling zones, and auxiliary drying air-cooled boxes. This systematically solves the inherent contradiction of existing integrated immersion phase change liquid cooling technology, which cannot simultaneously achieve high heat dissipation flux, high availability, and low total life cycle cost, and provides a scalable cooling architecture for high-density computing infrastructure.

[0018] By setting up server placement components, thermally insulated and sealed connection components one and two, and because the electronic components with different power consumptions in the computing server are partitioned, it is necessary to connect the different electronic components through photoelectric conversion signals. The photoelectric conversion signal connection can be achieved through thermally insulated and sealed connection components one and two, thereby assisting in the cooling of the computing server.

[0019] This invention also relates to a circulating heat exchange method for a partitioned immersion phase change liquid cooling heat exchange system of a computing server, characterized by comprising the following steps: a. Before using the present invention, the electronic components involved in the computing server are grouped into three power consumption groups: high, medium and low. The high, medium and low power consumption electronic components are respectively placed in the high power boiling zone, the medium power boiling zone and the auxiliary drying air-cooled box. The condensation component is sealed and installed above the liquid cooling box. The liquid cooling box is filled with coolant and the electronic components are immersed in it. The coolant absorbs the heat generated by the electronic components and gradually raises the temperature. After reaching the boiling point, the coolant boils and generates steam. The steam is condensed into liquid after exchanging heat with the condenser through the steam through hole path. The condensate is collected in the area that is offset from the steam through hole under the action of gravity. After the condensate is collected, it is transported to the medium-power boiling zone. The condensate level in the medium-power boiling zone rises and forms a static pressure difference at the connecting hole. This static pressure difference causes the perfluoroether rubber diaphragm to deform and lift, releasing the seal between it and the valve seat. This allows the coolant in the medium-power boiling zone to enter the high-power boiling zone through the opened gap, and gradually reduces the pressure difference. The perfluoroether rubber diaphragm can then gradually return to its original position and seal with the valve seat, thereby achieving partitioned immersion phase change liquid cooling heat exchange and circulating heat exchange for the computing server.

[0020] b. Due to the partitioned setup of electronic components with different power consumption, signal communication between electronic components in different areas can be achieved through optical / electrical signal conversion via thermally insulated sealing connection component one and thermally insulated sealing connection component two. Furthermore, thermally insulated sealing connection component one and thermally insulated sealing connection component two have built-in sealing monitoring structures. When the seal fails, the piston moves due to the pressure difference, completing the switching between the red and green plates of the indicator board, and simultaneously activating the audible and visual alarm circuit to make the audible and visual alarm work, thereby reminding the user that thermally insulated sealing connection component one and thermally insulated sealing connection component two need to be inspected, thus assisting in the partitioned liquid cooling and circulating heat exchange operation of electronic components with different power consumption.

Detailed Implementation

[0036] 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.

[0037] Please see Figures 1-13 The present invention provides a technical solution: a partitioned immersion phase change liquid cooling heat exchange system and a circulating heat exchange method for a computing server, comprising: a server placement component 100, a condensation component 200, a first thermally insulated sealing connection component 300, a second thermally insulated sealing connection component 400, and a one-way valve group 500. The server placement component 100 includes a liquid cooling box 101, a thermal insulation partition 102, a high-power boiling zone 103, a medium-power boiling zone 104, and an auxiliary drying air-cooled box 109. The heat insulation partition 102 is fixedly installed in the middle of the inner side of the liquid cooling box 101. The high power consumption boiling zone 103 is installed in the left side of the heat insulation partition 102. The medium power consumption boiling zone 104 is installed in the right side of the heat insulation partition 102. The auxiliary drying air cooling box 109 is installed in front of the liquid cooling box 101. The condenser assembly 200 is located above the liquid cooling box 101, the first thermal insulation sealing connection assembly 300 is installed on the rear side of the liquid cooling box 101, the second thermal insulation sealing connection assembly 400 is installed on the front side of the liquid cooling box 101 and located on the rear side of the auxiliary drying air cooling box 109, and the one-way valve assembly 500 is installed on the lower inner side of the thermal insulation partition 102. The condenser assembly 200 is used to condense the steam generated in the high-power boiling zone 103 and the medium-power boiling zone 104 into condensate, and to guide the condensate to the medium-power boiling zone 104. The one-way valve assembly 500 is used to form a one-way liquid replenishment channel from the medium-power boiling zone 104 to the high-power boiling zone 103 between the medium-power boiling zone 104 and the high-power boiling zone 103.

[0038] Please see Figures 1-8 and Figures 12-13 Example 1: The auxiliary drying air-cooled box 109 is filled with dry nitrogen and the coolant is circulated through the spiral tube built into the outer wall to achieve cooling and heat exchange. The spiral tube has a liquid inlet end and a liquid outlet end and is connected to the external coolant circulation pipeline. The condenser assembly 200 includes a top seat 201, a lower steam guide plate 202, an upper condensate receiving plate 203, a steam through hole 204, a V-shaped microchannel 209, a micro slit 210 and a condenser 213. The lower steam guide plate 202 is located inside the top seat 201, the upper condensate receiving plate 203 is located above the lower steam guide plate 202, and the condenser 213 is located at the upper end of the inner side of the top seat 201. Both the lower steam guide plate 202 and the upper condensate receiving plate 203 are inclined structures with the left side higher than the right side. Several steam through holes 204 are formed through the lower surface of the lower steam guide plate 202 and are linearly and equally distributed in the front, back and left and right directions. V-shaped microchannels 209 are formed on the upper surface of the upper condensate receiving plate 203 and are set along the left-high and right-low inclined structure of the upper condensate receiving plate 203. The micro-slits 210 are located below the V-shaped microchannels 209. The lower steam guide plate 202 and the upper condensate receiving plate 203 are both thin metal plates that are compatible with the coolant and have good hydrophilicity.

[0039] The steam through-hole 204 and the V-shaped microchannel 209 are arranged in an alternating structure in the front and back directions of the vertical structure. The lower steam guide plate 202 has a drainage groove 205 in the area below the micro-slit 210. The drainage ditch 205 is designed as an inverted trapezoid. Several sets of transverse branch ditches 206 are spaced apart at the front and rear ends of the lower steam guide plate 202 below the drainage ditch 205. The main drainage channel 207 is opened on the inner side of the front and rear ends of the lower steam guide plate 202. The transverse branch ditch 206 and the main drainage channel 207 are interconnected. Several sets of transverse branch grooves 206 are set to avoid the steam through hole 204. The transverse branch grooves 206 are set with a slightly inclined structure towards the main drain channel 207. The upper condensate receiving plate 203 is provided with a venting groove 211 above the steam through hole 204. A liquid-blocking cap 212 is fixedly connected above the upper condensate receiving plate 203 at the position of the venting groove 211, so that the condensate dripping from above is blocked from falling into the inside of the venting groove 211. The lower steam guide plate 202 has a liquid drop pipe 208 fixedly connected to the lower right side of both the front and rear sides. The liquid drop pipe 208 is set above the medium power boiling zone 104. The heat insulation plate 102 is composed of a middle heat insulation core layer in the middle position and metal cladding layers on both sides. The heat insulation plate 102 is higher than the highest liquid level and has a row of multiple through holes 105 to connect the steam space of the high power boiling zone 103 and the medium power boiling zone 104 to balance the overall pressure, but liquid is not allowed to pass through. The upper end of the heat insulation partition 102 is inclined, and its top surface is attached to the bottom surface of the lower steam guide plate 202.

[0040] After the coolant boils, it generates steam. The steam in the high-power boiling zone 103 and the medium-power boiling zone 104 rises and is condensed by the condenser component 200. During the rise, the steam is guided by the steam through the steam through hole 204 and enters the upper condenser 213 area. After the condensate falls, it first collects in the V-shaped microchannel 209 and then collects in the drop pipe 208 along the conveying path, so that the condensate can enter the medium-power boiling zone 104.

[0041] The lower right side of the heat insulation partition 102 has four sets of linearly and equally distributed connecting holes 108. The one-way valve assembly 500 is sealed and installed inside the connecting holes 108 by a sealing ring and fixed by bolts. The one-way valve assembly 500 includes a connecting flange 501, a valve seat 502, a valve seat 503, a valve core umbrella seat 504, a perfluoroether rubber diaphragm 505, and a limiting ring 506. The valve seat 502 is fixedly disposed on the left side of the connecting flange 501, the valve seat 503 is fixedly disposed on the inner side of the valve seat 502, and the valve core umbrella seat 504 is disposed on the inner side of the valve seat 503. A perfluoroether rubber diaphragm 505 is disposed around the valve core seat 504, and a limiting ring 506 is disposed on the left side of the perfluoroether rubber diaphragm 505. When the liquid level of the condensate in the medium power boiling zone 104 rises and a static pressure difference is formed at the connecting hole 108, the perfluoroether rubber diaphragm 505 bends up to open the one-way liquid replenishment channel from the medium power boiling zone 104 to the high power boiling zone 103. When the static pressure difference of the liquid column decreases to a level insufficient to open the perfluoroether rubber diaphragm 505, the perfluoroether rubber diaphragm 505 resets and seals against the valve seat 503.

[0042] As coolant gradually accumulates in the medium-power boiling zone 104, it compresses the steam space above, causing the pressure in the medium-power boiling zone 104 to rise. This pressure difference with the high-power boiling zone 103 causes the perfluoroether rubber diaphragm 505 to tilt upwards, causing the perfluoroether rubber diaphragm 505 to break free from the seal with the valve seat 503. This allows the coolant in the medium-power boiling zone 104 to flow into the high-power boiling zone 103 through the opened gap, thus achieving continuous replenishment of coolant between the two zones.

[0043] Specifically, in the use of the computing server involved in this invention, the electronic components involved are distinguished according to their power consumption. For example, high-power electronic components such as GPU / ASIC chips are integrated into the high-power boiling zone 103, medium-power electronic components such as CPU / high-bandwidth memory are integrated into the medium-power boiling zone 104, and low-power electronic components or temperature-insensitive electronic components such as motherboard, network card, management controller, cables and connectors are integrated into the auxiliary drying air-cooling box 109. The electronic components in the partitioned settings have different characteristics. The liquid cooling box 101 is filled with coolant and the electronic components placed therein are immersed. During operation, the electronic components in the high-power boiling zone 103 and the medium-power boiling zone 104 are liquid-cooled by the coolant. During the liquid cooling process, the coolant absorbs the heat generated by the electronic components and gradually heats the coolant to make it boil. The boiled coolant generates steam, which rises upwards. During transport, the steam first contacts the lower steam guide plate 202, then is guided through several evenly distributed steam through-holes 204, and then passes through the venting groove 211, through the upper condensate receiving plate 203, and finally enters the top space inside the top seat 201, where it exchanges heat with the condenser 213 to become condensate. The condensate falls to the upper condensate receiving plate 203 under gravity. First, due to the baffle 212, the condensate is blocked when it drips into the steam through-holes 204 area, then slides to all sides, entering the V-shaped channels before and after the baffle 212. The channel 209 has a micro-slit 210 below it, which allows the condensate to fall into the drainage trough 205 below. The drainage trough 205 has an inclined structure with the left side higher than the right side, which allows the condensate to be transported to the right side. During the movement, the condensate enters the transverse branch channel 206 and then enters the main drainage channels 207 on both sides. The main drainage channels 207 also have an inclined structure with the left side higher than the right side, which allows the condensate to be guided into the drop pipe 208. The drop pipe 208 is located in the medium power boiling zone 104, which allows the condensate to be evenly concentrated in the medium power boiling zone 104. Because the micro-slit 210 is extremely narrow and made of a hydrophilic material, the liquid will immediately fill the micro-slit 210 at the bottom of the tank due to the capillary effect, and flow through the micro-slit 210 into the lower drainage channel. The liquid-filled micro-slit itself forms a "liquid sealing curtain". Due to the surface tension and viscosity of the liquid, the rising steam has difficulty penetrating this liquid sealing slit to flow in the opposite direction. This achieves unidirectional transfer of liquid from top to bottom and isolation of gas from bottom to top. In addition, the steam passage 204 and the condensate falling area are set at intervals, and their paths are staggered and do not interfere with each other. Because the condensate in the above structure all collects in the medium-power boiling zone 104, the coolant level in this zone gradually rises. After the condensate collects in the medium-power boiling zone 104, the liquid level in the medium-power boiling zone 104 rises, forming a static pressure difference at the connecting hole 108 that is higher than that in the high-power boiling zone 103. This static pressure difference acts on the perfluoroether rubber diaphragm 505, causing the edge of the diaphragm to lift up and open the one-way replenishment channel, breaking away from the seal with the valve seat 503. The lifting of the perfluoroether rubber diaphragm 505 creates a connecting gap between it and the valve seat 503, allowing the coolant in the medium-power boiling zone 104 to flow freely. The liquid flows into the high-power boiling zone 103 through this gap. During the flow of the coolant, the liquid surface of the medium-power boiling zone 104 and the high-power boiling zone 103 and the pressure of the two spaces are balanced. When the pressure difference between the two is insufficient to cause the perfluoroether rubber diaphragm 505 to deform and lift, the perfluoroether rubber diaphragm 505 resets and fits against the valve seat 503, so that the two are sealed and the flow gap is closed. The perfluoroether rubber diaphragm 505 has the maximum degree of lifting, so that the limiting ring 506 limits the deformation of the perfluoroether rubber diaphragm 505 to prevent excessive deformation from affecting the performance of the perfluoroether rubber diaphragm 505. The perfluoroether rubber diaphragm 505 and the perfluorinated liquid (the coolant filled in the liquid cooling box in this invention) have good chemical stability and resistance to coolant immersion. During long-term immersion, there is no swelling, precipitation, or performance degradation, resulting in almost no substance precipitation and maintaining the insulation and purity of the working fluid. Furthermore, by adjusting the thickness (0.3-0.8 mm) and diameter, the perfluoroether rubber diaphragm 505 can easily achieve extremely low bending stiffness, keeping the opening threshold stably controlled within the range of 0.1-0.5 kPa with excellent repeatability. Its bending deformation exhibits non-linear stiffness characteristics—the initial deformation requires very little force (beneficial for low-pressure differential opening), and the stiffness gradually increases as the opening degree increases (preventing excessive deformation leading to instability or plastic deformation). This characteristic highly matches the ideal opening and closing curve of a one-way valve. In addition, the perfluoroether rubber diaphragm 505 can reduce the risk of diaphragm swelling, precipitation, and performance degradation, reducing maintenance frequency. Compared to the spring-driven one-way valve structure in existing technologies, it improves opening and closing stability. Based on the above-mentioned structure and their combined effects, this invention integrates high-, medium-, and low-power electronic components in the high-power boiling zone 103, the medium-power boiling zone 104, and the auxiliary drying air-cooling box 109 during use. This systematically solves the inherent contradiction that existing integrated immersion phase change liquid cooling technology cannot simultaneously achieve high heat dissipation flux, high availability, and low total life cycle cost, providing a scalable cooling architecture for high-density computing infrastructure.

[0044] Please see Figures 1-3 and Figures 9-11 Example 2: The thermal insulation and sealing connection assembly 300 includes a connecting cylinder 301, an isolation cavity 303, a sealing seat 304, an optical fiber bundle 305, and a micro photoelectric conversion module 306. The isolation cavity 303 is located in the middle of the inner side of the connecting cylinder 301. The fiber bundle 305 is located on the inner side of the isolation cavity 303 along the same axis as the isolation cavity 303. The fiber bundle 305 is made by melting, drawing and slicing thousands of single-mode optical fibers, and is covered with high borosilicate glass on the outside. Two sets of micro photoelectric conversion modules 306 are respectively located on both sides of the fiber bundle 305. Two sets of sealing seats 304 are located at both ends of the isolation chamber 303. The sealing seat 304 consists of a set of perfluoroether rubber O-rings and a set of metal C-type sealing rings to achieve the sealing of the isolation chamber 303. The isolation chamber 303 is pre-pumped to achieve a constant vacuum.

[0045] In use, the photoelectric conversion signal connection between the high-power boiling zone 103 and the medium-power boiling zone 104 is realized through the heat-insulating and sealing connection component 300. Because the heat-insulating and sealing connection component 300 can block the bidirectional permeation of fluids in the two spaces and block heat conduction, it can still transmit high-speed electrical / optical signals.

[0046] The thermally insulating and sealing connection assembly 300 also includes a monitoring seat 307, a pneumatic chamber 308, a piston 309, a retaining spring 310, a piston column 311, a sealing bellows 312, an external plate 313, a ratchet 314, and a ratchet seat 315. The monitoring base 307 is fixedly installed on the outside of the connecting cylinder 301, the air pressure chamber 308 is opened on the inside of the connecting cylinder 301 and faces the monitoring base 307, the piston 309 is movably installed on the inside of the air pressure chamber 308, the piston column 311 is fixedly connected to the side of the piston 309 near the monitoring base 307, and the retaining spring 310 is sleeved on the outside of the piston column 311. The sealing bellows 312 is fixedly installed at the outer end opening of the air pressure chamber 308, and the outer plate 313 is fixedly connected to the other end of the sealing bellows 312. The sealing bellows 312 is made of thin-walled stainless steel by hydraulic forming, and has good axial elasticity and absolute air tightness. The ratchet 314 is fixedly installed on the outside of the outer plate 313. A ratchet seat 315 is located in the inner cavity of the monitoring seat 307. A connecting column 316 is fixedly connected to one end of the ratchet seat 315 away from the axis of the monitoring seat 307. A connecting seat 317 is fixedly connected to the outside of the connecting column 316. A return spring 318 is sleeved on the outside of the connecting column 316. An indicator plate 319 is fixedly connected to the upper end of the connecting seat 317. The indicator plate 319 consists of two symmetrical structures, a green plate and a red plate. When the inner side of the isolation chamber 303 is in good condition, the green plate is exposed. When the seal inside the isolation chamber 303 fails, the red plate is exposed. The ratchet 314 and the ratchet seat 315 mesh with each other and can only move in one direction. An audible and visual alarm 320 is also fixedly installed inside the monitoring base 307. The audible and visual alarm 320 is electrically connected to an electrode plate 321 via a cable at one end near the connecting cylinder 301. The external plate 313 is also fixedly connected to an electrode plate 321 at the end away from the connecting cylinder 301. A button battery is also provided inside the monitoring base 307. The two electrode plates 321, the audible and visual alarm 320 and the button battery are connected in series and are set in a non-contact manner only between the two electrode plates 321. When the external plate 313 moves close to the audible and visual alarm 320, the two electrode plates 321 come into contact to achieve circuit conduction.

[0047] The heat-insulating sealing connection assembly 300 has an isolation chamber 303 inside. The isolation chamber 303 is pre-evacuated to achieve a constant vacuum. When the seal fails, the pressure inside the isolation chamber 303 will increase. Under the pressure difference with the air pressure chamber 308, the piston 309 will be pushed to move away from the connecting cylinder 301, and the outer plate 313 will follow. After the ratchet 314 enters the ratchet seat 315 area, the two will mesh and block the reverse movement. When the ratchet seat 315 is engaged, it will drive the connecting seat 317 to move, which will cause the indicator plate 319 to switch to expose the red plate. This will remind the user that the seal has failed. In this state, the audible and visual alarm 320 will also be triggered, and its starting circuit will be turned on to realize the audible and visual alarm.

[0048] Both ends of the connecting cylinder 301 are fixedly connected to a low thermal conductivity insulation structure ring 302, which is made of zirconia toughened ceramic material. The second insulation sealing connection component 400 is a three-way structure and has the same function as the first insulation sealing connection component 300. Two connection holes 106 are provided on both the front and rear sides of the liquid cooling box 101. The rear side of the auxiliary drying air cooling box 109 is also provided with a connection hole 106. Sealing flanges 107 are provided on the outer sides of the liquid cooling box 101 and the auxiliary drying air cooling box 109 at the coaxial position of the connection holes 106, and are fixedly connected to the low thermal conductivity insulation structure ring 302 by bolt pressing the sealing ring. One side connection hole 106 of the liquid cooling box 101 is connected to the high power boiling zone 103 and the medium power boiling zone 104 respectively. The heat insulation and sealing connection component 300 is used to realize the photoelectric conversion signal connection between the high power boiling zone 103 and the medium power boiling zone 104. The heat insulation and sealing connection component 400 is used to realize the photoelectric conversion signal connection between the high power boiling zone 103, the medium power boiling zone 104 and the auxiliary drying air cooling box 109. The thermally insulated sealing connection assembly 2 400 includes a three-way connecting cylinder, three low thermal conductivity thermal insulation structural rings 302, three sealing seats 304, at least two sets of optical fiber bundles 305, and miniature photoelectric conversion modules 306 respectively disposed at the three connection ends. The three connection ends correspond to the high power boiling zone 103, the medium power boiling zone 104, and the auxiliary drying air-cooled box 109, respectively. Each connection end of the three-way connecting cylinder is provided with an independent sealing seat to block fluid penetration between the corresponding zones. The optical fiber bundles 305 are used to transmit optical signals between the three zones.

[0049] Based on the first embodiment described above, further, in the use of this invention, because electronic components with different power consumptions are partitioned, it is necessary to connect the electronic components in different areas to achieve photoelectric conversion signals and block the permeation of fluid in the photoelectric conversion signal connection. This effect is achieved based on the heat-insulating sealing connection component 300 and the heat-insulating sealing connection component 400 provided in this invention. The heat-insulating sealing connection component 300 completes the circuit connection between the high-power boiling zone 103 and the medium-power boiling zone 104, and the heat-insulating sealing connection component 400 completes the circuit connection between the high-power boiling zone 103, the medium-power boiling zone 104 and the auxiliary drying air-cooling box 109. The electrical signal is first transmitted through the micro photoelectric conversion module 306, and then the electrical signal is converted into an optical signal. The optical signal can be transmitted through the optical fiber bundle 305, and then the circuit between the two areas is connected in the optical / electric conversion. Because the heat-insulating sealing connection component 300 and the heat-insulating sealing connection component 400 are set to block the bidirectional permeation of fluid in the two spaces and block heat conduction, they can still transmit high-speed electrical / optical signals. The isolation chamber 303 is pre-evacuated to a fixed vacuum level. When the seal of the isolation chamber 303 fails, the pressure will increase, which will disrupt the pressure difference between the isolation chamber 303 and the air pressure chamber 308 and the balance formed by the spring 310. This will cause the piston 309 to move away from the connecting cylinder 301, and drive the outer plate 313 to move along with it via the piston rod 311. This will cause the ratchet 314 to enter the ratchet seat 315 area and engage. The engagement between the two can achieve unidirectional movement and reverse locking, thereby blocking the reverse movement of the outer plate 313. When the ratchet seat 315 is engaged, it will drive the connecting seat 317 to move, thereby causing the indicator plate 319 to switch to expose the red plate, which is located externally to remind the user that the seal has failed. In this state, the audible and visual alarm 320 will also be triggered, which will activate its starting circuit to realize the audible and visual alarm, so that the operator can promptly inspect the abnormal parts. Once the alarm is deactivated and the isolation chamber 303 is re-vacuumed, pulling the connecting column 316 outward will disengage the ratchet 314 from the ratchet seat 315. Under the restoring force of the retaining spring 310, the external plate 313 will be reset, and the indicator plate 319 will be switched to green, thus deactivating the circuit of the audible and visual alarm 320. The above structures are all used to assist in the implementation of Embodiment 1, that is, to assist in the implementation of partitioning electronic components with different power consumption in the computing server.

[0050] This invention also relates to a circulating heat exchange method for a partitioned immersion phase change liquid cooling heat exchange system of a computing server, characterized by comprising the following steps: a. Before using the present invention, the electronic components involved in the computing server are grouped into three power consumption groups: high, medium, and low. The high, medium, and low power consumption electronic components are respectively integrated and placed in the high power boiling zone 103, the medium power boiling zone 104, and the auxiliary drying air-cooled box 109. The condensation component 200 is sealed and installed above the liquid cooling box 101. The liquid cooling box 101 is filled with coolant and the electronic components are submerged. The coolant absorbs the heat generated by the electronic components and gradually raises the temperature. After reaching the boiling point, the coolant boils and generates steam. The steam passes through the steam through hole 204 and exchanges heat with the condenser 213 before condensing into liquid. The condensate collects in the area offset from the steam through hole 204 under the action of gravity. After the condensate is collected, it is transported to the medium-power boiling zone 104. The liquid level of the condensate in the medium-power boiling zone 104 rises and forms a static pressure difference at the connecting hole 108. This static pressure difference causes the perfluoroether rubber diaphragm 505 to deform and lift up, releasing the seal between it and the valve seat 503. This allows the coolant in the medium-power boiling zone 104 to enter the high-power boiling zone 103 through the opened gap, and gradually reduces the pressure difference. The perfluoroether rubber diaphragm 505 can gradually return to its original position and seal with the valve seat 503, thereby realizing the partitioned immersion phase change liquid cooling heat exchange and circulating heat exchange of the computing server.

[0051] b. Due to the partitioned setup of electronic components with different power consumption, signal communication between electronic components in different areas can be achieved through optical / electrical signal conversion via thermally insulated sealing connection component 1 300 and thermally insulated sealing connection component 2 400. Furthermore, thermally insulated sealing connection component 1 300 and thermally insulated sealing connection component 2 400 have built-in sealing monitoring structures. When the seal fails, the piston 309 is triggered to move due to the pressure difference, completing the switching between the red and green plates of the indicator plate 319, and simultaneously activating the circuit of the audible and visual alarm 320, thus reminding the user that the thermally insulated sealing connection component 1 300 and thermally insulated sealing connection component 2 400 need maintenance, thereby assisting in the partitioned liquid cooling and circulating heat exchange operation of electronic components with different power consumption.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The second heat-insulating sealing connection component (400) is used to realize the photoelectric conversion signal connection between the high power boiling zone (103), the medium power boiling zone (104) and the auxiliary drying air cooling box (109). The second heat-insulating and sealing connection assembly includes a three-way connecting cylinder, three low thermal conductivity heat-insulating structural rings (302), three sealing seats, at least two sets of optical fiber bundles (305), and miniature photoelectric conversion modules (306) respectively disposed at the three connection ends. The three connection ends correspond to the high power boiling zone (103), the medium power boiling zone (104), and the auxiliary drying air-cooled box (109), respectively. Each connection end of the three-way connecting cylinder is provided with an independent sealing seat to block fluid penetration between the corresponding zones. The optical fiber bundles (305) are used to transmit optical signals between the three zones.

8. A circulating heat exchange method for a partitioned immersion phase change liquid cooling heat exchange system for a computing server as described in any one of claims 1-7, characterized in that: Includes the following steps: a. Before using the present invention, the electronic components involved in the computing server are grouped into three power consumption groups: high, medium and low. The high, medium and low power consumption electronic components are respectively placed in the high power consumption boiling zone (103), the medium power consumption boiling zone (104) and the auxiliary drying air cooling box (109). The condensation component (200) is sealed and installed above the liquid cooling box (101). The liquid cooling box (101) is filled with coolant and the electronic components are submerged. The coolant absorbs the heat generated by the electronic components and gradually raises the temperature. After reaching the boiling point, the coolant boils and generates steam. The steam passes through the steam through hole (204) and exchanges heat with the condenser (213) and condenses into liquid. The condensate collects in the area that is offset from the steam through hole (204) under the action of gravity. After the condensate is collected, it is transported to the medium power boiling zone (104). The liquid level of the condensate in the medium power boiling zone (104) rises and forms a static pressure difference at the connecting hole (108). This static pressure difference causes the perfluoroether rubber diaphragm (505) to deform and lift up, releasing the seal between it and the valve seat (503). This allows the coolant in the medium power boiling zone (104) to enter the high power boiling zone (103) through the opened gap, and gradually reduces the pressure difference. The perfluoroether rubber diaphragm (505) can gradually return to its original position and seal with the valve seat (503), thereby realizing the partitioned immersion phase change liquid cooling heat exchange and circulating heat exchange of the computing server. 9.b. Due to the partitioning of electronic components with different power consumption, in order to realize signal communication between electronic components in different areas, it can be achieved through the optical / electrical signal conversion via the first thermally insulated sealing connection component (300) and the second thermally insulated sealing connection component (400). The first thermally insulated sealing connection component (300) and the second thermally insulated sealing connection component (400) have built-in sealing monitoring structures. When the seal fails, the piston (309) is triggered to move due to the pressure difference, which completes the switching of the red and green plates of the indicator plate (319) and simultaneously conducts the circuit of the audible and visual alarm (320), which activates the audible and visual alarm (320) to make it work, thereby reminding the user that the first thermally insulated sealing connection component (300) and the second thermally insulated sealing connection component (400) need to be repaired, thereby assisting the partitioned liquid cooling and circulating heat exchange operation of electronic components with different power consumption.
