Description

Technical Field

[0001] The invention relates to the technical field of power cabinets, and in particular to a spray-type liquid-cooled power cabinet. Background Art

[0002] As power electronic equipment is rapidly developing towards high power density and miniaturization, traditional air-cooling technology can no longer meet the heat dissipation requirements of high heat flux density scenarios. Spray liquid cooling technology has gradually become one of the mainstream solutions for power cabinet heat dissipation due to its direct contact heat exchange, high thermal capacity and rapid temperature control capabilities. This technology sprays the cooling medium (such as water-based solution or insulating oil) directly onto the surface of the heat-generating components in the form of atomization or droplets, and uses the high thermal conductivity and latent heat of phase change of the liquid to achieve efficient cooling. However, the existing spray liquid cooling cabinets still have significant technical bottlenecks in practical applications and are in urgent need of optimization and improvement.

[0003] After searching, a Chinese patent with publication number CN220693615U discloses a spray-type liquid-cooled server cabinet, including a cabinet body, wherein a liquid storage tank and more than two spray boxes are arranged in the cabinet body, a plurality of liquid inlet elbows are arranged on the top of the spray box, and a plurality of liquid outlet elbows are arranged below the spray box, the liquid inlet elbows are connected to the liquid storage tank through a liquid inlet main pipe, and the liquid outlet elbows are connected to the liquid storage tank through a liquid return main pipe; a plurality of independently arranged sub-boxes are arranged in the spray box, and a server is arranged in each sub-box; a liquid distribution plate is arranged on the top of the sub-box, and the liquid inlet of the liquid distribution plate is connected to the corresponding liquid inlet elbow, and a liquid outlet is arranged at the bottom of the sub-box, and the liquid outlet is connected to the corresponding liquid outlet elbow.

[0004] Based on the above search and combined with the existing technology, it is found that the current spray system mostly adopts a fixed nozzle array or directional spray design, and its spray path and coverage area are limited by the nozzle layout and fluid dynamics. For power components with complex three-dimensional distribution (such as IGBT modules, transformers, busbars, etc.), it is difficult for the nozzle to achieve uniform full coverage spraying, which can easily lead to insufficient distribution of cooling medium in local hot areas (such as device edges and densely arranged areas). In addition, the spray angle and pressure adjustment range are limited, which further reduces its adaptability to non-planar or special-shaped heating elements, causing heat dissipation blind spots and affecting the overall temperature control uniformity; the existing technology relies on gravity to drive the cooling medium to flow naturally from the heating surface, and its flow rate is restricted by factors such as liquid viscosity, surface tension and device surface roughness, resulting in slow flow of the liquid film. Experimental studies have shown that under typical spray conditions, the average flow rate of the liquid film on the vertical surface is only 0.1-0.3m / s, and the residence time can reach several seconds to tens of seconds. During this period, after the cooling medium and the heating element undergo the initial heat exchange, its own temperature rises significantly (locally reaching the boiling point of the medium), and the thermal conductivity drops sharply. More importantly, the high-temperature retained liquid film will form a "thermal barrier effect", which will hinder the direct contact between the subsequent low-temperature coolant and the heating surface, greatly reducing the effective heat exchange temperature difference. Numerical simulations show that when the temperature of the retained liquid film increases by 10°C, the heat transfer efficiency of the subsequent spray liquid decreases by about 30%, and the cumulative effect of thermal resistance deteriorates nonlinearly with the increase of spray frequency, so there are limitations.

[0043] When the rotating tube 2 701 equipped with the rubber scraper 704 rotates, it can drive the rubber scraper 704 to flip synchronously, so that the end of the rubber scraper 704 can be used to scrape the thermal conductive back plate 601, so that the insulating cooling medium on the thermal conductive back plate 601 can be quickly detached after heat exchange, so that the thermal conductive back plate 601 can continue to exchange heat with the low-temperature insulating cooling medium.

[0045] Furthermore, the supporting mechanism includes two groups of end tubes 603 respectively fixedly mounted on the inner walls of the upper and lower ends of the cabinet 2, and a plurality of strip-shaped through grooves 604 are provided at the end of the end tube 603 away from the inner main body 6, and a plurality of through holes 606 distributed at equal distances are provided at the end of the end tube 603 close to the inner main body 6, and a plurality of piston rods 602 are fixedly mounted on the upper and lower ends of the inner main body 6, and the piston rods 602 are slidably matched with the inner wall of the end tube 603, and a return spring 605 is fixedly connected between the plurality of piston rods 602 and the inner wall of the cabinet 2; through the above structure, the piston rods 602 and the return springs 605 cooperate with each other to provide flexible support for the inner main body 6; at the same time, the piston rods 602 cooperate with the end tube 603 to limit the inner main body 6, ensuring that it can only move slightly in the vertical direction;

[0046] When the piston rod 602 moves to the position area of ​​the strip groove 604, the air or insulating cooling medium on the outside can enter between the piston rod 602 and the end tube 603. When the piston rod 602 moves toward the through hole 606, the air or insulating cooling medium can be sprayed toward the upper and lower ends of the inner body 6, thereby achieving a certain auxiliary and cooling effect.

[0047] As a further solution of the present invention, one end of the plurality of rotating tubes 1 7 and 701 are movable through the cabinet 2 and extend to the outside, and gears 702 are fixedly installed on the outer peripheral walls of the ends of the rotating tubes 1 7 and 701.

[0048] Furthermore, a rack 501 is slidably installed on the outer wall of one side of the cabinet 2 in the vertical direction, and convex teeth are provided on both sides of the rack 501, and the rack 501 is meshed with the adjacent gear 702; through the above structure, when the rack 501 moves back and forth in the vertical direction, it can drive the rotating tube 1 7 and the rotating tube 2 701 to rotate back and forth slightly through the transmission action of the gear 702.

[0050] Furthermore, a driving motor 8 is fixedly installed on the top of the cabinet 2, and mutually meshing transmission conical teeth 801 are fixedly installed between the middle end of the output shaft of the driving motor 8 and the fan shaft 802, a rotating wheel 803 is fixedly installed on the end of the output shaft of the driving motor 8, and a boss 804 is fixedly installed on one side of the rotating wheel 803, a folding connecting rod 806 is fixedly installed on the top of the top column 4, and a long circular groove rod 805 is fixedly installed on the end of the folding connecting rod 806, and the long circular groove rod 805 is slidably matched with the boss 804.

[0051] Through the above structure, when the driving motor 8 is controlled to start, the transmission effect of the transmission cone teeth 801 can drive the fan shaft 802 to rotate, thereby realizing the operation of the blowing mechanism; at the same time, the driving motor 8 can drive the rotating wheel 803 to rotate, and through the cooperation of the protruding column 804 and the long round groove rod 805, it can drive the folded connecting rod 806 to move back and forth in the vertical direction, thereby cooperating with the support spring 502 and the top column 4, driving the inner body 6 to reciprocate in the vertical direction; and when the top column 4 moves up and down, the two racks 501 can be driven by the conductive frame 5 to move synchronously, thereby realizing the swing drive of the rotating tube 1 7 and the rotating tube 2 701;

[0052] When the inner body 6 moves back and forth vertically, on the one hand, it can indirectly increase the effective range of the insulating cooling medium and improve the cooling effect. On the other hand, it can utilize the inertia effect to throw off the insulating cooling medium that has undergone heat exchange on the surface of the inner body 6, so that the inner body 6 can always be in rapid contact with the ejected insulating cooling medium, so as to further improve the cooling effect.

[0053] Furthermore, a top cover 202 is fixedly installed on the top of the cabinet 2 near the driving motor 8, one end of the folded connecting rod 806 is slidably connected to the top cover 202 in the vertical direction, and a side cover 201 is fixedly installed on one side of the cabinet 2, and the side cover 201 is slidably connected to the two racks 501 in the vertical direction; the side cover 201 is provided to protect the internal racks 501 and gears 702.

[0054] As a further solution of the present invention, in order to quickly discharge the insulating cooling medium accumulated at the bottom of the cabinet 2, a curved cavity plate 203 is fixedly installed on one side of the inner bottom of the cabinet 2, and a horizontal shaft 902 is rotatably installed inside the cabinet 2, one end of the horizontal shaft 902 is located on the outside of the cabinet 2 and is fixedly installed with a driven gear disk 901, and a plurality of equally spaced arc scrapers 903 are fixedly installed on the outer peripheral wall of the horizontal shaft 902, and a transmission gear ring 9 is sleeved on one end of the rotating tube 7 located at the lowest end, and the transmission gear ring 9 is meshed with the driven gear disk 901.

[0055] Furthermore, a plurality of equally spaced triangular cavities 904 are provided on the inner circumferential wall of the transmission gear ring 9, a plurality of equally spaced receiving grooves 16 are provided on the rotating tube 7 on which the transmission gear ring 9 is sleeved, and a tensioning spring 162 is fixedly installed on the inner bottom of the receiving groove 16, and a trapezoidal block 161 that slides with the receiving groove 16 is fixedly installed at the end of the tensioning spring 162, and the end of the trapezoidal block 161 is adapted to the triangular cavities 904.

[0056] Through the above structure, as shown in the attached Figure 8-Figure 9 As shown in the figure, when the rotating tube 7 rotates clockwise, the trapezoidal block 161 will form a snap fit with the triangular cavity groove 904, so that the rotating tube 7 can drive the transmission gear ring 9 to rotate, and through the transmission action of the driven gear plate 901, drive the horizontal shaft 902 and the arc scraper 903 to rotate; when the rotating tube 7 rotates counterclockwise, the inclined surface of the trapezoidal block 161 and the triangular cavity groove 904 generate a force. At this time, as shown in the attached Fig.10 As shown, the trapezoidal block 161 will be recovered into the storage groove 16. At this time, the rotating tube 7 will not be able to drive the transmission gear ring 9 to rotate. In summary, although the rotating tube 7 in the present application rotates back and forth, it can only drive the horizontal axis 902 and the arc scraper 903 to rotate in one direction, thereby driving the insulating cooling medium at the bottom of the cabinet 2 to flow in one direction, so as to avoid the situation where part of the insulating cooling medium remains inside the cabinet 2 for a long time.

[0057] As a further solution of the present invention, a cooling box 3 is fixedly installed on one side of the top outer wall of the base 1, and a circulating pump 303 is fixedly connected to one side of the cooling box 3, a liquid extraction pipe 306 is fixedly connected between the input end of the circulating pump 303 and the cabinet 2, a circulating pipe 302 is fixedly connected to the output end of the circulating pump 303, and the circulating pipe 302 is fixedly passed through the interior of the cooling box 3, a refrigerator 301 is fixedly installed on one side of the cooling box 3, and the refrigerator 301 is used to cool the heat exchange medium inside the cooling box 3, and the end of the circulating pipe 302 is fixedly connected to a mother pipe 304, and the ends of the main pipe 304 are fixedly connected with a pair of branch pipes 305, and the branch pipes 305 are rotatably connected with the rotating pipe 1 7 and the rotating pipe 2 701; through the above structure, when the circulating pump 303 is in operation, the insulating cooling medium at the bottom of the cabinet 2 can be drawn out nearby and sent into the circulating pipe 302, and the insulating cooling medium is restored to a low-temperature state by exchanging heat with the heat exchange medium in the cooling box 3. Finally, the insulating cooling medium is transported to the main pipe 304, the branch pipe 305, the rotating pipe 1 7 and the rotating pipe 2 701 in sequence through the circulating pipe 302.

[0058] The specific working method is: when in use, the driving motor 8 and the circulating pump 303 are running, and when the driving motor 8 is started, the transmission cone gear 801 drives the fan shaft 802 to rotate, thereby realizing the operation of the blowing mechanism; at the same time, the driving motor 8 drives the rotating wheel 803 to rotate, and through the cooperation of the convex column 804 and the long circular groove rod 805, drives the folded connecting rod 806 to move back and forth in the vertical direction, thereby cooperating with the support spring 502 and the top column 4, driving the inner body 6 to reciprocate in the vertical direction; and when the top column 4 moves up and down, the conductive frame 5 can be used to drive the two racks 501 to move synchronously, and under the transmission action of the rack 501 and the gear 702, the rotating tube 1 7 and the rotating tube 2 701 are reciprocatingly swung, so that the insulating cooling medium is sprayed onto the inner body 6 more evenly, thereby improving the cooling effect of the inner body 6;

[0059] When the rotating tube 2 701 equipped with the rubber scraper 704 rotates, the rubber scraper 704 is driven to turn synchronously, so that the end of the rubber scraper 704 is used to scrape the heat-conducting back plate 601, so that the insulating cooling medium on the heat-conducting back plate 601 can be quickly separated after heat exchange, so that the heat-conducting back plate 601 can continue to exchange heat with the low-temperature insulating cooling medium. At the same time, when the rubber scraper 704 is turned to the bottom, the insulating cooling medium on its surface can be thrown to the bottom of the cabinet 2 under the action of inertia;

[0060] When the inner body 6 moves back and forth vertically, on the one hand, the scope of action of the insulating cooling medium can be indirectly increased, and the cooling effect can be improved. On the other hand, the insulating cooling medium that has undergone heat exchange on the surface of the inner body 6 can be thrown off by inertia, so that the inner body 6 is always in rapid contact with the ejected insulating cooling medium, so as to further improve the cooling effect. When the circulating pump 303 is running, the insulating cooling medium at the bottom of the cabinet 2 can be drawn out nearby and sent into the circulating pipe 302. By exchanging heat with the heat exchange medium in the cooling box 3, the insulating cooling medium is put into a low-temperature state again. Finally, the insulating cooling medium is transported to the main pipe 304, the branch pipe 305, the rotating pipe 1 7 and the rotating pipe 2 701 in sequence through the circulating pipe 302, and finally ejected from the set nozzle 703.

[0061] The purpose of the blower mechanism is to accelerate the air to one side of the inner body 6, thereby accelerating the heat dissipation of the inner body 6, and promoting the falling speed of the insulating cooling medium on the surface where the electrical components are installed, reducing the retention time, so that the low-temperature insulating cooling medium sprayed out later can contact the surface more quickly to ensure the cooling effect; at the same time, when the rotating tube 7 is turned back and forth, the ball head rod 15 is used to contact the end cavity plate 142, thereby pushing the folding plate 14 with the air outlet 141 to swing back and forth, so as to achieve the purpose of increasing the air outlet range of the blower mechanism;

[0062] In order to quickly discharge the insulating cooling medium accumulated at the bottom of the cabinet 2, as shown in the attached Figure 8 - Fig. 9 As shown in the figure, when the rotating tube 7 rotates clockwise, the trapezoidal block 161 will form a snap fit with the triangular cavity groove 904, so that the rotating tube 7 can drive the transmission gear ring 9 to rotate, and through the transmission action of the driven gear plate 901, drive the horizontal shaft 902 and the arc scraper 903 to rotate; when the rotating tube 7 rotates counterclockwise, the inclined surface of the trapezoidal block 161 and the triangular cavity groove 904 generate a force. At this time, as shown in the attached Fig.10 As shown, the trapezoidal block 161 will be recovered into the storage groove 16. At this time, the rotating tube 7 will not be able to drive the transmission gear ring 9 to rotate. In summary, although the rotating tube 7 in the present application rotates back and forth, it only drives the horizontal axis 902 and the arc scraper 903 to rotate in one direction, thereby driving the insulating cooling medium at the bottom of the cabinet 2 to flow in one direction, so as to avoid the situation where part of the insulating cooling medium remains inside the cabinet 2 for a long time.
