TECHNICAL FIELD

[0001] The present application relates to the field of heat dissipation technology, in particular to a spraying type liquid cooling heat dissipation device for small energy storage equipment. BACKGROUND

[0002] Energy storage power stations can store electricity during peak load periods of the power system and release electricity when the load is low, thereby balancing the difference between power supply and demand, improving the stability and reliability of the power grid, reducing dependence on traditional power generation facilities, and quickly responding to voltage and frequency fluctuations in the power system by releasing or absorbing electricity to regulate the voltage and frequency of the power grid, ensuring the normal operation of the power system. It can also be used as a backup power source to provide temporary power support in the event of power system failures or emergencies, ensuring the continuous operation of critical facilities and services. Small energy storage equipment itself uses battery packs for energy storage, and the core role of energy storage equipment is to optimize energy management through energy storage and release, mainly reflected in stabilizing power supply and demand fluctuations, enhancing grid stability, improving renewable energy utilization, and ensuring emergency power supply. In the event of power grid failure, energy storage can provide emergency power for important power users or machines.

[0005] To achieve the above purpose, the present application provides the following technical scheme, a spraying type liquid cooling heat dissipation device for small energy storage equipment, comprising a warehouse body: The inner surface of the chamber is provided with a flow guide plate. A coolant storage tank is connected to one side of the chamber. A coolant guide pipe is connected to the top of the coolant storage tank. A water pump is provided on one side of the coolant guide pipe. A pipe installation port is sleeved on the outer wall of one end of the water pump. A coolant distribution pipe is connected to one end of the coolant guide pipe. A nozzle is provided on the bottom surface of the coolant distribution pipe. A placement rack is provided below the nozzle. A coolant distribution groove is provided on the bottom surface of the placement rack. Lateral flow guide holes are provided on both sides of the placement rack.

[0006] Preferably, the surface of the compartment can be sealed with a transparent cabinet door, and the guide plate can guide the unused coolant falling from directly above.

[0007] Preferably, the guide plate can guide the coolant into the coolant storage tank, which has a water pump that can extract the coolant from the guide plate.

[0008] Preferably, the pump can extract coolant from the coolant storage tank and supply it to the coolant guide pipe, and the placement rack is provided in multiple sets and inserted into the tank body.

[0009] Preferably, the placement rack and the coolant diversion channel cooperate to form a rectangular space. The coolant diversion channel and the side guide holes can be used to divert unused coolant to the next layer. The coolant diversion channel and the side guide holes can be used to install battery pack clamps or screws and other fixing components.

[0010] Preferably, the bottom of the placement rack is connected to two vertical control hoses on both sides, the inner side of the vertical control hoses is connected to a horizontal support hose, the top of the vertical control hoses is connected to a reel frame, a control guide rod is inserted inside the reel frame, concave fixing brackets are sleeved on the outer walls of both ends of the control guide rod, an adjusting gear is connected to one end of the control guide rod, a transmission shaft is meshed on one side of the adjusting gear, a forward and reverse motor is connected to the top surface of the transmission shaft, a motor mounting bracket is connected to the bottom of the forward and reverse motor, and a dust cover is provided on the top of the reel frame.

[0011] Preferably, the lateral support hose is supported on one side of the bottom end of the placement rack, the vertical control hose and the lateral support hose form a rectangular structure and are sleeved on one side of the outer wall of the placement rack, the lateral support hose is connected to one side of the bottom surface of the placement rack, the top surface of the compartment is provided with a groove, and the bottom end of the concave fixing bracket is connected to one side of the inner wall of the groove provided in the compartment.

[0012] Preferably, the chamber body and the dust cover are hinged together, and slots are provided on both sides of the inner wall of the slot in the chamber body. The top end of the vertical control hose passes through the slot in the chamber body and is connected to the hose reel.

[0013] Preferably, the tube roll frame and the control guide rod are fixedly connected, and the concave fixed bracket has positioning holes on both sides. The control guide rod is inserted into the positioning holes of the concave fixed bracket and is movably connected to the concave fixed bracket.

[0014] Preferably, the motor mounting bracket is connected to one side surface of the compartment body, and a limiting groove is formed on the top surface of the motor mounting bracket. The bottom end of the forward and reverse motor passes through the limiting groove formed in the motor mounting bracket and is connected to the transmission shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The placement rack is inserted into the compartment, and the compartment is used to position the rack on both sides. The battery pack is then placed within the rectangular space formed by the placement rack and the coolant distribution channel. The battery pack is then secured using clamps or screws installed through the coolant distribution channel or side guide holes. To dissipate heat from the battery pack, a water pump is used to draw coolant from the coolant reservoir and supply it to the coolant guide pipe. The pipe is positioned and supported using the pipe mounting port, ensuring the coolant supply is directed to the coolant distribution pipe. Finally, the coolant is sprayed onto the battery pack using nozzles. On the surface, excess coolant is diverted downwards using coolant distribution channels and side guide holes, ensuring each layer is covered by coolant. The remaining coolant is then guided within the guide plate, allowing the coolant reservoir to draw it out for recycling. A transparent cabinet door provides real-time observation of the interior, enabling the recycling of coolant and allowing for multi-layer reuse. This avoids the problem of coolant being sprayed onto the battery pack surface but unable to flow to other areas, resulting in coolant only being sprayed on the top layer for cooling and preventing multi-layer reuse and waste.

[0016] 2. The slot at the top of the compartment is sealed by adjusting the angle of the dust cover. The forward and reverse motors are then turned on, causing the drive shaft to rotate. This, in turn, causes the drive shaft to rotate the adjusting gear meshing on one side. The concave fixed bracket supports the control guide rod, while the reel frame fixed to the outer surface of the control guide rod rotates with it. This causes the reel frame to wind up the vertical control hose. The angle of the placement rack is adjusted using the vertical control hose in conjunction with the horizontal support hose, allowing excess coolant in the placement rack and coolant distribution tank to flow downwards. The forward and reverse motors can drive the placement rack to rotate in both directions, creating repeated motion to accelerate the evaporation and condensation of coolant on the battery pack surface, thus improving heat dissipation efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 One embodiment provided by the present invention: A spray-type liquid cooling heat dissipation device for small energy storage equipment includes a housing 11: The inner surface of the tank body 11 is provided with a flow guide plate 12. A coolant storage tank 13 is connected to one side of the tank body 11. A coolant guide pipe 14 is connected to the top of the coolant storage tank 13. A water pump 15 is provided on one side of the coolant guide pipe 14. A pipe installation port 16 is sleeved on the outer wall of one end of the water pump 15. A coolant distribution pipe 17 is connected to one end of the coolant guide pipe 14. A nozzle 18 is provided on the bottom surface of the coolant distribution pipe 17. A placement rack 19 is provided below the nozzle 18. A coolant distribution groove 20 is provided on the bottom surface of the placement rack 19. Lateral flow guide holes 21 are provided on both sides of the placement rack 19. The internal material of the tank body 11 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application. Therefore, no further details are provided. Furthermore, a transparent cabinet door can be installed on the surface of the tank body 11 for sealing, and the guide plate 12 can guide the unused coolant falling from directly above, so as to guide the unused coolant through the guide plate 12 and prevent the coolant from accumulating inside the tank body 11.

[0021] Furthermore, the guide plate 12 can guide the coolant to the coolant storage tank 13. The coolant storage tank 13 has a water pump inside, which can extract the coolant in the guide plate 12. This allows the coolant in the guide plate 12 to be pumped into the coolant storage tank 13 by the water pump inside the coolant storage tank 13 for recycling, thus avoiding waste.

[0022] Furthermore, the pump 15 can extract the coolant from the coolant storage tank 13 and supply it to the coolant guide pipe 14. Multiple sets of placement racks 19 are provided and inserted into the compartment 11, so that the placement racks 19 can be positioned by the compartment 11, and the placement racks 19 can be used in conjunction with the coolant distribution channel 20 to position and support the battery pack, and the battery pack can be arranged in multiple layers.

[0023] Furthermore, the placement rack 19 and the coolant diversion channel 20 cooperate to form a rectangular space. The coolant diversion channel 20 and the side guide holes 21 can be used to divert unused coolant to the next layer. The coolant diversion channel 20 and the side guide holes 21 can be used to install battery pack clamps or screws and other fixing components, so as to achieve the effect of positioning the battery pack clamps or screws and other matching fixing components through the coolant diversion channel 20 and the side guide holes 21, and can also be used to divert excess coolant.

[0024] Furthermore, vertical control hoses 22 are connected to both sides of the bottom end of the placement rack 19. A horizontal support hose 23 is connected to the inside of the vertical control hose 22. A reel rack 24 is connected to the top of the vertical control hose 22. A control guide rod 25 is inserted inside the reel rack 24. A concave fixing bracket 26 is sleeved on the outer wall of both ends of the control guide rod 25. An adjusting gear 27 is connected to one end of the control guide rod 25. A transmission shaft 28 is meshed on one side of the adjusting gear 27. A forward and reverse motor 29 is connected to the top surface of the transmission shaft 28. A motor mounting bracket 30 is connected to the bottom end of the forward and reverse motor 29. A dust cover 31 is provided on the top of the reel rack 24. The forward and reverse motor 29 drives the placement rack 19 to rotate in both directions, thereby performing repeated movements to accelerate the rapid evaporation and condensation of the coolant on the surface of the battery pack, thus improving heat dissipation efficiency.

[0025] Furthermore, the horizontal support hose 23 is supported on one side of the bottom end of the placement frame 19. The vertical control hose 22 and the horizontal support hose 23 form a rectangular structure and are sleeved on one side of the outer wall of the placement frame 19. The horizontal support hose 23 is connected to one side of the bottom surface of the placement frame 19. A groove is opened on the top surface of the compartment 11. The bottom end of the concave fixing bracket 26 is connected to one side of the inner wall of the groove opened in the compartment 11, so that the bottom end of the concave fixing bracket 26 can be limited by the groove opened in the compartment 11, so that the concave fixing bracket 26 can stably support the control guide rod 25 and the coil frame 24.

[0026] Furthermore, the compartment 11 and the dust cover 31 are hinged. The inner wall of the compartment 11 has slots on both sides. The top of the vertical control hose 22 passes through the slots in the compartment 11 and connects to the hose reel 24. This allows the hose reel 24 to be moved and limited through the slots in the compartment 11, and the vertical control hose 22 can be wound up by rotating the angle of the hose reel 24, thereby adjusting the angle of the placement rack 19.

[0027] Furthermore, the tube roll frame 24 and the control guide rod 25 are fixedly connected. The concave fixed bracket 26 has positioning holes on both sides. The control guide rod 25 is inserted into the positioning holes of the concave fixed bracket 26 and is movably connected to the concave fixed bracket 26. This allows the control guide rod 25 to be positioned and stably supported through the positioning holes of the concave fixed bracket 26, so that the control guide rod 25 can rotate inside the positioning holes of the concave fixed bracket 26.

[0028] Furthermore, the motor mounting bracket 30 is connected to one side surface of the compartment 11. A limiting groove is formed on the top surface of the motor mounting bracket 30. The bottom end of the forward and reverse motor 29 passes through the limiting groove formed in the motor mounting bracket 30 and is connected to the transmission shaft 28. This allows the forward and reverse motor 29 and the transmission shaft 28 to be positioned by the limiting groove formed in the motor mounting bracket 30, and the forward and reverse motor 29 to be fixed by the motor mounting bracket 30. This allows the forward and reverse motor 29 to drive the adjusting gear 27 meshing on one side of the transmission shaft 28 to rotate. The motor mounting bracket 30 also protects the adjusting gear 27 and the transmission shaft 28 at the front end, preventing dust from entering and causing the transmission effect between the adjusting gear 27 and the transmission shaft 28 to become stuck.

[0029] Working principle: When performing spray-type liquid cooling treatment on small energy storage devices, the placement rack 19 is inserted into the chamber 11, and the chamber 11 is used to position the two sides of the placement rack 19. The battery pack is then placed in the rectangular space formed by the placement rack 19 and the coolant distribution channel 20. The battery pack is then fixed by the matching clamps or screws installed in the coolant distribution channel 20 or the side guide holes 21. When cooling the battery pack, the coolant in the coolant storage tank 13 is drawn by the pump 15 and supplied to the coolant guide pipe 14 for guidance. The coolant is guided through the pipe installation port 16. The pipe 14 is positioned and supported, so that the coolant guide pipe 14 supplies coolant to the coolant distribution pipe 17, and sprays it onto the surface of the battery pack using the nozzle 18. The excess coolant is diverted downwards by the coolant distribution groove 20 and the side guide hole 21, so that each layer can be covered by coolant. Then the remaining coolant is guided in the guide plate 12, so that the coolant storage tank 13 draws the coolant in the guide plate 12 for recycling. The contents of the compartment 11 can be observed in real time through the transparent cabinet door, so as to realize the recycling of coolant and multi-layer use to avoid waste.

[0030] When adjusting the spray-type liquid cooling device for small energy storage equipment, the groove at the top of the compartment 11 is closed by adjusting the angle of the dust cover 31, and the forward and reverse motor 29 is turned on, causing the forward and reverse motor 29 to drive the transmission shaft 28 to rotate. This causes the transmission shaft 28 to drive the adjusting gear 27 meshing on one side to rotate. While the concave fixed bracket 26 supports the control guide rod 25, the coil frame 24 fixedly connected to the outer surface of the control guide rod 25 rotates with the control guide rod 25, causing the coil frame 24 to wind up the vertical control hose 22. The vertical control hose 22, in conjunction with the horizontal support hose 23, controls the angle adjustment of the placement rack 19, causing the excess coolant inside the placement rack 19 and the coolant diversion tank 20 to flow downwards. The forward and reverse motor 29 can drive the placement rack 19 to rotate in both directions, thus performing repeated movements to accelerate the rapid evaporation and condensation of coolant on the surface of the battery pack, thereby increasing the heat dissipation efficiency.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
