Description

Technical Field

[0001] This invention relates to the field of energy storage thermal management technology, and specifically provides an integrated liquid-cooled circulating heat dissipation device for prefabricated energy storage compartments. Background Technology

[0002] Large-capacity prefabricated energy storage compartments generally adopt a composite heat dissipation mode with liquid cooling as the main method and air cooling as an auxiliary method. The liquid cooling pipelines circulate low-temperature media to achieve heat exchange of the battery cells, and the supporting fans guide the hot air in the compartment to balance the ambient temperature. Conventional equipment has two independent drive motors for the top heat extraction fan and the side mobile blowing fan. The condensate on the outer wall of the pipeline drips directly to the bottom of the compartment. The circulating water circuit is only equipped with a simple filter to intercept impurities. Each heat dissipation component is arranged independently without an integrated linkage structure. The entire heat dissipation system realizes the functions of heat exchange, air blowing and impurity filtration separately. It is widely used in industrial and commercial and grid-side energy storage compartment temperature control scenarios and can meet the basic charging and discharging heat dissipation requirements. However, many structural defects have been exposed during long-term use.

[0003] Existing cooling solutions use dual fans with separate motors, resulting in poor synchronization and potential for localized temperature differences within the cooling chamber. Multiple motors also occupy space and increase energy consumption. Furthermore, the lack of a condensate recovery system in the cooling pipes leads to corrosion of high-voltage components and requires frequent manual replenishment. Ordinary filters only intercept fine impurities and cannot settle large scale particles, easily clogging the microchannel liquid cooling plates. To address these shortcomings, this invention designs a single-motor dual-fan structure, equipped with a condensate drip collection and return chamber and a stratified sedimentation and filtration cavity. This integrates air-cooling linkage, water circulation and recovery, and water purification into a single unit. By relying on component synergy, it improves temperature control uniformity, enhances equipment safety, reduces maintenance costs, and solves several inherent problems of traditional cooling devices. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention features a single-motor linkage air-cooling mechanism that synchronously drives a top fan and a vertically reciprocating dual-power fan using the same motor. Synchronous operation of the two fans is achieved through a first gear, a ring gear, a transmission belt, and a rotating threaded rod, eliminating the need for a separate drive motor. This effectively reduces overall energy consumption and the space occupied within the prefabricated energy storage compartment. The simultaneous operation of the dual fans allows for the simultaneous extraction of hot air from the upper part of the compartment and the complete vertical purging of the energy storage compartment, eliminating localized high-temperature zones caused by asynchronous operation of traditional dual-motor fans, resulting in a more uniform temperature distribution of the battery cells. The entire mechanical linkage structure relies on ratchet and ring ratchet gears to ensure that the dual-power fans rotate in only one direction, ensuring stable operation. Reducing the number of motors also lowers the probability of future electrical failures, significantly simplifying the assembly and maintenance process of the energy storage compartment's cooling system.

[0016] 2. This invention features a collection tank below the water-cooled pipe to collect condensate dripping from the pipe wall. The collected water is then returned to the water-cooling circulation system via a connecting pipe for reuse. This prevents condensate from dripping directly and corroding high-voltage components such as the energy storage compartment inside the chamber, while also reducing the frequency of manual coolant replenishment and lowering long-term maintenance costs. The connecting pipe integrates an isolation inclined plate, an upper flow plate, and a lower flow plate to form an anti-backflow channel. When the connecting pipe rotates, the condensate inside the collection tank is drawn into the second cooling tank. At the same time, fine impurities are intercepted by the filter tank, while large particles of scale and metal debris settle due to gravity. This effectively prevents impurities from clogging the heat exchange channels of the water-cooled pipe. The air-cooling mechanism and the water-cooling circulation mechanism work together to recover condensate and replenish the circulation medium, while the filtration mechanism continuously purifies the water path, ensuring long-term stable operation of the liquid cooling system.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-11The device shown is an integrated liquid-cooled circulating heat dissipation device for prefabricated energy storage compartments, including a prefabricated energy storage compartment body 1, an energy storage compartment 4, and a first isolation plate 5 and a second isolation plate 6 fixedly connected inside the prefabricated energy storage compartment body 1. The prefabricated energy storage compartment body 1 is equipped with a wind-cooling mechanism 2 that blows air on both sides of the energy storage compartment 4 to achieve auxiliary cooling. The prefabricated energy storage compartment body 1 and the rear side of the energy storage compartment 4 are equipped with a water-cooling circulating mechanism 3 for water cooling of the energy storage compartment 4. The wind-cooling mechanism 2 and the water-cooling circulating mechanism 3 can work together to provide composite cooling for the energy storage compartment 4. The water-cooling circulating mechanism 3 is equipped with a condensate collection and recovery structure, which can collect the condensate droplets generated on the pipe wall during water cooling operation and transport them to the circulation pipeline to participate in heat exchange again.

[0022] The air-cooling mechanism 2 includes a rotating threaded rod 200 rotatably connected inside the energy storage prefabricated cabin body 1. A movable frame 201 is slidably connected to the side surface of the first isolation plate 5. A rotating plate 202 and a dual-power fan 204 are rotatably connected inside the movable frame 201. A ring ratchet gear 203 is rotatably connected to the outer surface of the rotating plate 202. A first rotating shaft 205 is fixedly connected to one side of the rotating plate 202. A first trapezoidal gear 206 is fixedly connected to one side of the first rotating shaft 205. A ratchet 207 is rotatably connected to one side of the rotating plate 202. A first spring 208 is fixedly connected to the bottom end of the ratchet 207. A fixed plate 209 is fixedly connected to one side of the movable frame 201. A rotating tube 210 is rotatably connected to the upper surface of the fixed plate 209. A second trapezoidal gear 211 is fixedly connected to the outer surface of the rotating tube 210. A limit groove 212 is formed inside the rotating threaded rod 200. A limit block 213 is fixedly connected inside the rotating tube 210. A power motor 214 and an air intake 216 are fixedly connected to the side surface of the second isolation plate 6. A first gear 215 is fixedly connected to the output shaft of the power motor 214. A top fan 217 is rotatably connected inside the air intake 216. A ring gear 218 is fixedly connected to the outer surface of the top fan 217. A second gear 219 and a first roller 220 are fixedly connected to the outer surface of the rotating threaded rod 200. A transmission belt 221 is driven to the outer surface of the first roller 220. A ratchet 207 is engaged inside the ring ratchet gear 203. The ring ratchet gear 203 is meshed with the dual power fan 204. A first trapezoidal gear 206 is meshed with the second trapezoidal gear 211. The rotating threaded rod 200 is threadedly connected inside the moving frame 201. A limiting block 213 is slidably connected inside the limiting groove 212. The first gear 215 and the ring gear 218 are meshed. The ring gear 218 is meshed with the second gear 219.

[0023] Furthermore, the power output of the motor 214, via the first gear 215 meshing with the ring gear 218, drives the top fan 217 to continuously rotate and extract hot air from the cabin. The extracted hot air is drawn into the rear side of the second isolation plate 6 through the air intake 216, and cooled down by the water cooling pipe 301. Simultaneously, the first roller 220 and the transmission belt 221 drive the second roller 308, the second rotating shaft 307, the worm gear 319, and the rotating threaded rod 200 to rotate. The rotating threaded rod 200 drives the moving frame 201 to rise and fall vertically along the guide rail. The moving frame 201 is equipped with a dual-power fan 204, and the first trapezoidal gear 206 meshes with the second trapezoidal gear 211 to drive the dual-power fan. The 204 fan continuously blows air, and the ring ratchet gear 203 and ratchet 207 work together to achieve unidirectional self-locking of the transmission. This allows the dual-power fan 204 to rotate and blow air only when the moving frame 201 moves downward. The two sets of fans are driven synchronously by a single power motor 214, eliminating the need for an independent motor, reducing the internal space occupied by the energy storage prefabricated compartment 1, and reducing the overall energy consumption. The top fan 217 operates synchronously with the vertically moving dual-power fan 204, providing uniform blowing to the entire energy storage compartment 4 and eliminating local high temperature differences. The self-locking structure of the ring ratchet gear 203 and ratchet 207 prevents reverse transmission, resulting in higher operational reliability. The number of motors is reduced, the number of electrical fault points is lowered, and assembly and subsequent maintenance operations are simpler.

[0024] The water-cooling circulation mechanism 3 includes a water-cooling pipe 301 fixedly connected inside the first isolation plate 5. A first cooling tank 302 and a second cooling tank 303 are fixedly connected inside the energy storage prefabricated cabin body 1. A collection trough 304 is fixedly connected to the lower inner surface of the energy storage prefabricated cabin body 1. A collection inclined plate 305 is fixedly connected inside the collection trough 304. A connecting pipe 306 is fixedly connected inside the collection inclined plate 305. A second rotating shaft 307 is rotatably connected inside the collection inclined plate 305. The top end of the second rotating shaft 307... A second roller 308 is fixedly connected to the outer surface of the second cooling box 303. A closed cover 309 is fixedly connected to the inside of the second cooling box 303. A filter tank 310 is slidably connected to the inside of the second cooling box 303. An isolation inclined plate 311 is fixedly connected to the inside of the connecting pipe 306. A first water outlet 312, a second water inlet 313, and a first water inlet 314 are opened on the side surface of the connecting pipe 306. An upper water flow plate 315 and a lower water flow plate 316 are fixedly connected to the inside of the connecting pipe 306. The outer surface of the second rotating shaft 307 is sleeved. A pressing spring 317 is connected to the second rotating shaft 307. A sealing plate 318 is slidably connected to the outer surface of the second rotating shaft 307. A worm gear 319 is fixedly connected to the outer surface of the second rotating shaft 307. A collection tank 304 is located below the water cooling pipe 301. A connecting pipe 306 is inserted into the interior of the second cooling tank 303 and communicates with the first cooling tank 302 and the collection tank 304. The water cooling pipe 301 communicates with the interior of the first cooling tank 302 and the second cooling tank 303. The pressing spring 317 is located on the upper water flow plate 315 and the sealing plate 318. Between 8, the inside of the collection tank 304 is connected to the second cooling box 303 through the first water inlet 314 and the first water outlet 312. The sealing cover 309 is set at the upper end of the filter tank 310. The water cooling pipe 301 is connected to the inside of the sealing cover 309 through the second cooling box 303. The second cooling box 303 is connected to the first cooling box 302 for circulation through the second water inlet 313. The first roller 220 and the second roller 308 are connected by a transmission belt 221. The air intake 216 is connected to the rear side of the second isolation plate 6.

[0025] Furthermore, the low-temperature medium flows inside the water-cooled pipe 301. Water droplets condense on the pipe wall upon contact with the hot air inside the chamber. These droplets drip downwards and collect in the bottom collection tank 304. After being guided and gathered by the collection inclined plate 305, they flow through the first inlet 314 into the connecting pipe 306, and then through the first outlet 312 into the second cooling tank 303. The first cooling tank 302 replenishes coolant to the second cooling tank 303 through the second inlet 313. The mixed condensate and coolant circulate in a closed-loop system, mixing with the existing coolant before re-entering the water-cooled pipe 301 for heat exchange, achieving closed-loop recycling and reuse of the condensate. When the circulating coolant flows through the water-cooled pipe 301 into the second cooling tank 303, it first passes through the filter tank 310 for diversion. Large particles of scale and metal debris settle inside the filter tank 310 due to gravity. The condensate then flows upwards through the upper flow plate 315 and the lower flow plate 316. The 6-layer partition has a pressing spring 317 that presses the sealing plate 318 to allow condensate to flow upwards in one direction. The second rotating shaft 307, pressing spring 317, and sealing plate 318 work together to form a water pumping channel. Condensate and circulating coolant pass through the interior of the second cooling tank 303 and are sent to the water-cooled pipe 301 through the second water inlet 313 to complete the heat exchange cycle. The collection tank 304 can collect all the condensate on the outer wall of the water-cooled pipe 301, preventing water droplets from dripping directly and soaking the high-voltage components of the energy storage compartment 4, thus eliminating the safety hazard of short-circuit corrosion. The condensate is recycled to the circulation pipeline to continuously replenish the medium, greatly reducing manual liquid replenishment operations and reducing long-term maintenance workload. The recycled water is integrated with the main circulation water circuit, eliminating the need for additional water storage equipment, simplifying the pipeline layout in the compartment, and improving space utilization. At the same time, the air-cooling mechanism 2 and the water-cooling circulation mechanism 3 are connected by a transmission belt 221.

[0026] The main compartment door 101 is slidably connected to the front interior of the prefabricated energy storage compartment 1. The side compartment door 102 is rotatably connected to the side interior of the prefabricated energy storage compartment 1. The sliding groove 103 is fixedly connected to the lower interior surface of the prefabricated energy storage compartment 1. The storage rack 104 is provided inside the prefabricated energy storage compartment 1. The bottom end of the storage rack 104 is rotatably connected to the moving wheel 105. The storage rack 104 has a lower ventilation groove 106 inside. The support side plate 107 is fixedly connected to the storage rack 104. The upper surface of the support side plate 107 is slidably connected to the sliding plate 108. The sliding plate 108 has a middle ventilation groove 109 inside. The lower end of the sliding plate 108 has a rotating ball 110 inside. The support side plate 107 has a sliding groove 111 inside. The moving wheel 105 is slidably connected inside the sliding groove 103. The rotating ball 110 is slidably connected inside the sliding groove 111. The energy storage compartment 4 is located above the sliding plate 108.

[0027] Furthermore, the air-cooling mechanism 2 and the water-cooling circulation mechanism 3 are mechanically linked and start and stop synchronously, resulting in faster temperature control response. The temperature difference control effect of the battery cells in the energy storage compartment 4 is significantly improved. Condensation recovery and impurity filtration are integrated inside the water-cooling system. One set of equipment solves multiple pain points such as uneven heat dissipation, dripping corrosion, frequent water replenishment, and pipeline blockage. The overall integrated structure reduces the number of independent parts, lowers equipment manufacturing costs, and is compatible with the standardized mass production and on-site prefabrication of the prefabricated energy storage compartment body 1.

[0028] Working principle: During operation, the power motor 214 outputs power uniformly. One path drives the top fan 217 to rotate via the meshing of the first gear 215 and the ring gear 218, drawing in the high-temperature air inside the energy storage prefabricated cabin body 1 and sending it to the rear side of the second isolation plate 6 to exchange heat with the outer wall of the water-cooling pipe 301, thus reducing the basic temperature inside the cabin. The other path drives the threaded rod 200 to rotate via the second gear 219, the first roller 220, and the transmission belt 221. The threaded rod drives the moving frame 201 to vertically reciprocate up and down along the side wall of the first isolation plate 5, coordinating with the first Trapezoidal gear 206 and second trapezoidal gear 211 drive annular ratchet gear 203 to rotate. When annular ratchet gear 203 rotates, it drives dual-power fan 204 to rotate. When rotating threaded rod 200 rotates, it drives rotating tube 210 to rotate. Thus, second trapezoidal gear 211 drives first trapezoidal gear 206 to rotate. Annular ratchet gear 203 and ratchet 207 achieve unidirectional self-locking. It only blows the energy storage compartment 4 during the downward phase to eliminate local high temperature of the battery and realizes that a single motor can simultaneously complete top heat extraction and full-area mobile air cooling.

[0029] The cryogenic coolant circulates within a closed pipeline formed by the water-cooled pipe 301, the first cooling tank 302, and the second cooling tank 303, providing liquid cooling to the base of the energy storage compartment 4. Water droplets continuously condense on the walls of the cryogenic pipes in contact with the hot air inside the compartment. The water droplets drip down to the collection tank 304 below by gravity. After being guided and gathered by the collection inclined plate 305, they are transported through the first water inlet 314 to the connecting pipe 306 for temporary storage. This unified collection of the condensate generated by the water cooling prevents water droplets from directly dripping and soaking the high-voltage components of the energy storage compartment 4, thus eliminating the safety hazards of short circuits and corrosion.

[0030] The transmission belt 221 synchronously drives the second roller 308, the second rotating shaft 307, and the worm gear 319 on the water-cooled side to rotate. Together with the pressing spring 317 and the sealing plate 318, a one-way water pumping channel is formed to pump the condensate in the connecting pipe 306 into the circulating water circuit. The medium flows through the filter tank 310 for sedimentation. Large particles of impurities settle due to gravity, while small impurities are intercepted by the partition. The clean medium flows back to the water-cooled pipe 301 through the filter tank 310 and the second water inlet 313 for repeated heat exchange. The air-cooling mechanism 2 and the water-cooling circulation mechanism 3 work synchronously through mechanical linkage with the same motor. The air cooling reduces the chamber temperature and reduces the amount of condensate produced, while the water cooling completes heat exchange, water replenishment, and water circuit self-purification. The two work together to stably control the battery operating temperature.
