An adaptive data center phase change liquid cooling cycle heat dissipation device

Abstract

This invention relates to the field of phase change liquid cooling radiator technology, specifically an adaptive data center phase change liquid cooling circulation heat dissipation device. It mainly includes an evaporator, inside which, from top to bottom, are arranged a spray mechanism, a heat exchange structure, and a liquid lifting mechanism, with seven heat exchange structures in total. This invention achieves a dual-drive rotation mechanism through the spray drive of the spray mechanism and the steam acceleration of the pneumatic mechanism. This allows the thickness of the liquid film formed by the phase change coolant on the surface of the heat exchange cone of the heat exchange structure to dynamically adjust with the heat flux density. When the heat flux density increases, the vaporized gas impacts the pneumatic fan blades, accelerating the rotation of the power tube and all heat exchange structures. Combined with the guiding effect of the first and second conical spiral grooves, the liquid film spreads thinner. When the heat flux density decreases, the gas thrust weakens, and the rotation speed of the heat exchange structure adaptively decreases, resulting in a reasonable matching of the liquid film thickness. This completely solves the problem that the liquid film of traditional falling film evaporators cannot adapt to load fluctuations, ensuring stable heat exchange under different computing power scenarios.

Description

Technical Field

[0001] This invention relates to the field of phase change liquid cooling radiator technology, specifically an adaptive data center phase change liquid cooling circulation heat dissipation device. Background Technology

[0002] With the continuous increase in computing power density in data centers, the heat flux density of core heat-generating components such as server CPUs and GPUs has increased dramatically, placing stringent demands on the heat exchange efficiency, stability, and adaptability of cooling systems. Currently, mainstream data center phase change liquid cooling systems mainly consist of cold plates, evaporators, condensers, connecting pipes, liquid storage tanks, and control components. These components work together to form a closed-loop heat dissipation cycle: the liquid storage tank, as the storage unit for the phase change coolant, is connected to the inlet of the evaporator via a supply pipe, continuously supplying liquid phase change coolant to the evaporator. The evaporator, as the core heat exchange unit, directly exchanges heat with the server's heat-generating components through conduction via the cold plate or direct contact with the heat flow. After absorbing heat within the evaporator, the phase change coolant vaporizes to form a gaseous working fluid. The working fluid is transported to the condenser through the return vapor pipeline. The condenser cools and condenses the gaseous working fluid into a liquid state through air cooling or water cooling. The liquid then flows back to the storage tank through the return liquid pipeline to complete the cycle. The control components monitor the system operating parameters in real time through temperature, pressure, and flow sensors deployed at each key node. They also control the coolant supply and circulation speed by adjusting valve opening and pump power to ensure the stable operation of the heat dissipation system. In existing phase change liquid cooling systems, the structure of the evaporator directly determines the heat exchange efficiency. The mainstream types include flooded, dry, and falling film evaporators.

[0003] Existing falling film evaporators still have significant technical defects in practical applications: First, when the heat flux density of a data center fluctuates with the computing load, the thickness of the liquid film formed by the spray cannot be dynamically adjusted. When the heat flux density increases, the liquid film does not absorb enough heat, resulting in insufficient vaporization efficiency and the generation of hot spots. When the heat flux density decreases, the liquid film is too thick, resulting in wasted heat exchange area. Second, the unvaporized coolant needs to be collected in a sump and then returned to the storage tank by an additional pump or gravity. The return path is long and the response is slow, which means that this part of the coolant cannot quickly re-enter the spray cycle to participate in heat dissipation, resulting in low coolant utilization and indirectly reducing the overall heat dissipation efficiency. Third, the liquid film spreading effect depends on gravity, resulting in poor thickness uniformity, slow flow speed, and a lack of enhancement mechanism for the vaporization process. When the heat flux density increases sharply, the coolant vaporization rate cannot increase synchronously, resulting in lag in heat dissipation and difficulty in quickly controlling the temperature of the heating elements within a safe range, which seriously affects the stable operation of data center equipment.

[0004] Therefore, we propose an adaptive data center phase change liquid cooling cycle heat dissipation device. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive data center phase change liquid cooling circulation heat dissipation device to solve the problems mentioned in the background art, such as the inability to dynamically adapt the liquid film thickness when the heat flux density fluctuates with the computing load, slow return response and low utilization of unvaporized phase change coolant, uneven liquid film spreading and insufficient vaporization rate leading to heat dissipation lag.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention achieves a dual-drive rotation mechanism through the spray drive of the spray mechanism and the steam acceleration of the pneumatic mechanism. This allows the thickness of the liquid film formed by the phase change coolant on the surface of the heat exchange cone of the heat exchange structure to be dynamically adjusted according to the heat flux density. When the heat flux density increases, the vaporized gas impacts the pneumatic fan blades, accelerating the rotation of the power tube and all heat exchange structures. With the guiding effect of the first and second cone spiral grooves, the liquid film spreads thinner. When the heat flux density decreases, the gas thrust weakens, and the rotation speed of the heat exchange structure adaptively decreases. The liquid film thickness is reasonably matched, completely solving the problem that the liquid film of traditional falling film evaporators cannot adapt to load fluctuations, and ensuring stable heat exchange under different computing power scenarios.

[0022] This invention achieves mechanical self-circulation of phase change coolant through a liquid lifting mechanism driven by a rotating heat exchange structure. The transfer pipe of the bottom heat exchange structure drives the drive disc to rotate, and through the linkage ball and linkage rod, the power piston is driven to reciprocate radially. The unvaporized phase change coolant at the bottom of the evaporator is drawn into the annular jacket through the liquid suction pipe and liquid suction check valve, and then quickly flows back to the spray pipe through the liquid outlet check valve and liquid outlet pipe to participate in heat dissipation again. No additional pumping device is required, and the return path is short and the response is fast. Compared with the traditional gravity return or external pump return method, the coolant utilization rate is significantly improved, indirectly enhancing the overall heat dissipation efficiency of the system.

[0023] This invention utilizes the centrifugal force of the rotating heat exchange structure, combined with the guiding effect of the conical spiral guide groove and the re-dividing hole on the inner wall of the receiving cone tube, to enable the phase change coolant to rapidly spirally spread on the surface of the heat exchange cone, forming an ultra-thin uniform liquid film and extending the flow path. At the same time, the vortex-shaped flow channel extends the heat flow residence time, and the airflow of the annular air channel blows across the liquid film surface at close range, accelerating the vaporization rate of the phase change coolant. When the heat flux density increases sharply, the heat dissipation capacity can be improved simultaneously, completely solving the problem of heat dissipation lag in traditional devices and further ensuring the high-temperature safety and stable operation of core equipment in data centers.

[0062] Working principle

[0063] First, the heat flow rises through the heat inlet pipe 104. Then, it passes through the lower rotary joint 322, intermediate pipe 321, lower splicing pipe 308, and bend pipe 306 to enter the edge of the truncated cone channel 304 inside the bottom heat exchange structure 3. Next, the heat flow follows the trajectory of the vortex-shaped flow channel 311 towards the center of the truncated cone channel 304, increasing the distance the heat flow travels within the truncated cone channel 304 and thus increasing the residence time. This allows the heat flow to heat the heat exchange cone 301 more thoroughly. Furthermore, the special structure of the vortex-shaped plate 310 increases the heating surface area, making heat transfer between the heat flow and the heat exchange cone 301 faster. Simultaneously, the vortex-shaped flow channel 304, constrained by its inner wall, further enhances the heat transfer efficiency. The closer the channel 311 is to the center of the heat exchange cone 301, the longer its vertical length; the closer the vortex-shaped channel 311 is to the edge of the heat exchange cone 301, the shorter its vertical length. This special structure can further increase the residence time and heat transfer area of ​​the heat flow inside the conical channel 304, resulting in faster heat transfer. The heat flow then flows along the trajectory of the vortex-shaped channel 311 into the central cavity, and then enters the adjacent heat exchange structure 3 above through the upper splicing pipe 302. Following the same principle, the heat flow sequentially passes through the remaining heat exchange structures 3 and enters the uppermost heat exchange structure 3. The uppermost heat exchange structure 3 then discharges the heat flow through its top upper splicing pipe 302, power pipe 203, upper rotary joint 205, and heat outlet pipe 105, and then undergoes phase change cooling. The coolant enters the spray plate 202 through the cold inlet pipe 106 and the spray pipe 201. Then, the spray plate 202 sprays the phase change coolant onto the surface of the heat exchange cone 301 of the top heat exchange structure 3 through spray holes. Heat exchange occurs between the heat exchange cone 301 and the phase change coolant, causing the phase change coolant to vaporize. The phase change coolant then flows obliquely downward along the surface of the heat exchange cone 301 and falls into the receiving cone 314. Next, the phase change coolant flows along the inner wall of the receiving cone 314 into the collecting cone 316. Then, the phase change coolant flows along the inner wall of the collecting cone 316 onto the surface of the redistribution cone 318. After that, the phase change coolant slides along the surface of the redistribution cone 318 to the top surface of the heat exchange cone 301 and falls into the next heat exchange structure through the redistribution hole 317. On the surface of the heat exchange cone 301 of structure 3, the unvaporized phase change coolant passes through the remaining heat exchange structures 3 sequentially from top to bottom, following the same principle. These remaining heat exchange structures 3 exchange heat with the unvaporized phase change coolant in turn, ultimately accumulating on the bottom surface of the evaporator 101's inner cavity. A liquid level monitor 108 monitors the liquid level in real time and sends the data to an external control component. The external control component controls the pumping speed of the phase change coolant. When the liquid level exceeds a preset value within the control component, the control component reduces the pumping speed; when the liquid level is below the preset value, the control component increases the pumping speed. This dynamic balance control of the phase change coolant's entry avoids ineffective energy consumption and achieves higher energy utilization. Simultaneously...The phase change coolant sprayed from the spray plate 202 impacts the power impeller 204, causing it to be thrust counterclockwise. Under this thrust, the power impeller 204 rotates counterclockwise through the power pipe 203, carrying all the heat exchange structures 3. Then, under the combined action of centrifugal force and rotational force, and guided by the first and second conical spiral grooves 312 and 313, the phase change coolant on the top surface of the heat exchange cone 301 rapidly spirals outwards. This faster spiraling and longer travel along the heat exchange cone 301 results in higher heat exchange efficiency and improved heat dissipation. The gas generated by the vaporization of the phase change coolant flows upwards through the annular gap and annular air passage. The gas is blown across the liquid film surface formed by the phase change coolant on the inner side of the receiving cone tube 314, which helps to further increase the vaporization rate and improve the heat dissipation effect. The gas passes upward through the constriction shell 401 and the exhaust pipe 107 and is discharged. When the gas passes through the constriction shell 401, the gas exerts a rotational force on the pneumatic fan blade 402, which then accelerates the rotational speed of the power tube 203, thereby accelerating the rotational speed of the heat exchange structure 3. The faster the rotational speed of the heat exchange structure 3, the thinner and faster the phase change coolant spreads, which helps to increase the vaporization rate and the heat dissipation rate. The higher the heat flow temperature, the faster the phase change coolant vaporizes, changing from liquid to gas, with a significant increase in volume. The pressure difference further accelerates the pneumatic fan blades. The lower the rotational speed of 402, the slower the vaporization of the phase change coolant, resulting in a smaller pressure difference. This pressure difference provides less kinetic energy for the rotation of the pneumatic fan blade 402. Consequently, the heat exchange structure 3 gradually decelerates under various resistances during subsequent rotations until a new equilibrium is reached, thus automatically adapting to temperature changes in the heat flow. The rotation of the heat exchange structure 3 also drives the drive disc 507 through the transfer pipe 321. The drive disc 507 then alternately applies radial thrust to the three linkage rods 511 through the engagement of the inner wall of the drive ring groove 508 and the linkage ball 512. When the linkage rods 511 are subjected to radial thrust, they gradually move the power piston 510 away from the central column cavity 505. Then, the power piston 51... The phase change coolant inside the annular jacket 503 is compressed. The coolant flows back to the spray plate 202 through the outlet check valve 518, outlet pipe 519, and spray pipe 201. As the drive disc 507 rotates, the radial thrust on the linkage rod 511 disappears. Then, the linkage spring 513 pulls the power piston 510 radially closer to the central column cavity 505. A negative pressure is then formed inside the annular jacket 503. The phase change coolant accumulated at the bottom of the evaporator cylinder 101 enters the annular jacket 503 under the pressure difference through the suction pipe 516 and suction check valve 517. This lifts the unvaporized phase change coolant at the bottom of the evaporator cylinder 101 to the spray plate 202 for reuse.
