Description

Technical Field

[0001] This utility model relates to the field of battery box cooling nozzle technology, and in particular to a long curved tube battery box flow-guiding cooling nozzle. Background Technology

[0002] In fields such as new energy vehicles and energy storage power stations, long curved tube battery boxes serve as the core load-bearing components of battery packs, and their heat dissipation performance directly affects the safety and lifespan of the batteries. Long curved tube battery boxes achieve a compact layout and efficient space utilization of battery modules through their internal winding and tortuous pipe design. To solve the heat dissipation problem, flow-guided cooling nozzles have emerged. These nozzles optimize the coolant spray path, precisely delivering coolant to key heat-generating areas of the battery box to improve cooling efficiency. Existing flow-guided cooling nozzles incorporate a filter structure inside the nozzle to filter impurities in the coolant and prevent clogging of the nozzle orifices.

[0003] Because coolant often contains impurities, the filter inside the nozzle used to filter impurities is very easy to become clogged during long-term use. Once the filter is clogged, the flow of coolant is obstructed, which will not only reduce the spray pressure and flow rate, resulting in a significant decrease in cooling efficiency, but may also cause abnormal internal pressure of the nozzle and damage the nozzle structure. Utility Model Content

[0004] In view of the fact that the filter screen inside the nozzle is prone to clogging during long-term use, once the filter screen is clogged, the flow of coolant is obstructed, which not only reduces the spray pressure and flow rate, resulting in a significant decrease in cooling efficiency, but may also cause abnormal internal pressure of the nozzle and damage the nozzle structure, this utility model provides a long curved tube battery box flow-guiding cooling nozzle with the advantage of self-cleaning of the filter component inside the filter screen, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a long curved tube battery box flow-guiding cooling nozzle, including a nozzle body, a filter plate provided in the middle of the inner wall of the nozzle body, and a self-cleaning component provided in the outer ring and inside of the nozzle body;

[0006] The self-cleaning component includes multiple water outlets that are circumferentially connected to the bottom of the nozzle body. A ring plate is located on the outer periphery of the nozzle body. Multiple drive plates are fixedly installed on the inner wall of the ring plate. Multiple connecting plates are fixedly installed at the bottom of the ring plate. A rotating rod is fixedly installed at the other end of each connecting plate. The upper end of the rotating rod penetrates the bottom of the nozzle body and is fixedly installed with a compensation rod. A movable sleeve is slidably installed on the upper end of the compensation rod. A drive rod is fixedly installed on the upper end of the movable sleeve. The upper end of the drive rod penetrates the middle of the filter plate and is fixedly installed with a limiting plate. Multiple scrapers are fixedly installed circumferentially on the side of the limiting plate, with the bottom of the scrapers fitting against the upper end of the filter plate.

[0007] Preferably, a guide post is fixedly installed on the inner bottom of the nozzle body, and a sliding groove is opened inside the guide post. A T-shaped rod is fixedly installed on the bottom of the filter plate, and the T-shaped rod is slidably installed inside the guide post. A compression spring is fixedly installed on the bottom of the T-shaped rod.

[0008] The guide columns provide axial guidance for the up-and-down movement of the filter plate, ensuring smooth movement and accurate positioning of the filter plate.

[0009] Preferably, the drive rod is rotatably mounted inside the T-shaped rod, the inner wall of the movable sleeve is provided with a cross-shaped groove, and the upper end of the compensation rod is slidably mounted in the cross-shaped groove on the inner wall of the movable sleeve.

[0010] The groove inside the movable sleeve allows the compensating rod to slide axially with the movable sleeve while restricting circumferential rotation, ensuring stable transmission when the filter plate moves.

[0011] Preferably, a baffle plate is fixedly installed at the bottom of the filter plate, and the position of the baffle plate corresponds to the position of the multiple water outlet holes. When the filter plate blockage is impacted downward by the liquid force, the water outlet holes are located at the upper edge of the filter plate, and the liquid is discharged from the multiple water outlet holes.

[0012] By setting up the baffle, the filter plate blocks the water outlet when it is not clogged, and exposes the water outlet after the blockage moves down, thus controlling the coolant discharge path.

[0013] Preferably, the axial position of the water outlet is matched with the axial height of the drive plate, and the spray direction of the plurality of water outlets is tangentially corresponding to the impact surface of the drive plate at the corresponding position, so that the coolant directly acts on the force-bearing area of ​​the drive plate after being sprayed out.

[0014] Preferably, the inner wall of the nozzle body is provided with multiple slide rails, and the side of the filter plate is circumferentially fixed with multiple sliders that are adapted to the slide rails, and the sliders are slidably installed inside the slide rails.

[0015] The slide rails provide guidance and support for the up-and-down movement of the filter plates, preventing them from tilting or shifting and ensuring smooth movement.

[0016] Preferably, a sealed bearing is provided at the rotatable connection between the rotating rod and the bottom of the nozzle body, and the upper and lower ends of the drive rod located on the outside of the T-shaped rod are provided with limiting protrusions.

[0017] Preferably, a threaded connector is fixedly installed at the upper end of the nozzle body, and multiple nozzles are uniformly fixedly installed at the bottom of the nozzle body.

[0018] This utility model has the following advantages:

[0019] 1. By setting a self-cleaning component, when coolant flows in from the threaded joint at the top of the nozzle body, is filtered by the filter plate, and sprays out from the bottom nozzle, if the filter plate is clogged by impurities, causing an increase in pressure above, the filter plate will squeeze the compression spring downwards under the force of the liquid. At this time, the baffle plate at the bottom of the filter plate no longer blocks the water outlet, and the coolant sprays out from the water outlet through the circumferential opening, impacting the drive plate on the inner wall of the ring plate. The drive ring plate drives the connecting plate and the rotating rod to rotate. The rotating rod drives the drive rod to rotate through the compensation rod and the movable sleeve. The limit plate and scraper at the top of the drive rod rotate accordingly. The scraper continuously scrapes the upper surface of the filter plate to remove the attached impurities, realizing the self-cleaning of the filter plate, avoiding filter screen clogging that affects cooling efficiency, and preventing abnormal internal pressure of the nozzle from damaging the structure.

[0020] 2. By setting guide posts at the bottom inside the nozzle body, when the filter plate moves downward due to blockage, the guide posts provide axial sliding guidance for the filter plate, and the compression spring provides reset force, ensuring smooth up and down movement of the filter plate. When the filter plate moves downward, the high-pressure coolant is discharged through the water outlet, which not only provides a power foundation for the self-cleaning structure at the top of the filter plate, but also allows the coolant to be discharged normally to dissipate heat and cool the battery box, realizing the dual functions of self-cleaning power supply and emergency heat dissipation. This avoids the cooling failure caused by filter screen blockage and ensures that the battery box maintains heat dissipation during the filter plate cleaning process. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 A long curved tube battery box flow-guiding cooling nozzle includes a nozzle body 1, a filter plate 31 in the middle of the inner wall of the nozzle body 1, and a self-cleaning component 5 in the outer ring and inside of the nozzle body 1.

[0029] The self-cleaning component 5 includes multiple water outlet holes 501, which are circumferentially opened at the bottom of the nozzle body 1. A ring plate 502 is provided at the outer ring position in the middle of the nozzle body 1. Multiple drive plates 503 are fixedly installed on the inner wall of the ring plate 502. By setting the self-cleaning component 5, when the coolant flows in from the threaded joint 2 at the upper end of the nozzle body 1, is filtered by the filter plate 31 and sprayed out from the bottom nozzle 6, if the filter plate 31 is blocked by impurities, causing the pressure above to increase, the filter plate 31 will squeeze the compression spring 44 downward under the action of the liquid force. At this time, the baffle plate 32 at the bottom of the filter plate 31 no longer blocks the water outlet holes 501, and the coolant sprays out from the circumferentially opened water outlet holes 501, impacting the drive plates 503 on the inner wall of the ring plate 502.

[0030] Please see Figures 2-3 Multiple connecting plates 504 are fixedly installed at the bottom of the ring plate 502. A rotating rod 505 is fixedly installed at the other end of each connecting plate 504. The drive plate 503, impacted by the coolant sprayed from the water outlet 501, rotates circumferentially around the axis of the nozzle body 1. The upper end of the rotating rod 505 penetrates the bottom of the nozzle body 1 and is fixedly installed with a compensating rod 506. A movable sleeve 507 is slidably installed at the upper end of the compensating rod 506. A drive rod 508 is fixedly installed at the upper end of the movable sleeve 507. The upper end of the drive rod 508 penetrates the middle of the filter plate 31 and is fixedly installed with a limit plate 509. Multiple scrapers 510 are fixedly installed on the side circumferentially of the position plate 509. The bottom of the scraper 510 is in contact with the upper end of the filter plate 31. The drive ring plate 502 drives the connecting plate 504 and the rotating rod 505 to rotate. The rotating rod 505 drives the drive rod 508 to rotate through the compensation rod 506 and the movable sleeve 507. The limiting plate 509 and the scraper 510 at the upper end of the drive rod 508 rotate accordingly. The scraper 510 continuously scrapes the upper surface of the filter plate 31 to remove the attached impurities, realize the self-cleaning of the filter plate 31, avoid the filter screen from being blocked and affecting the cooling efficiency, and at the same time prevent abnormal internal pressure of the nozzle from damaging the structure.

[0031] Please see Figures 3-4A guide post 41 is fixedly installed on the inner bottom of the nozzle body 1. A groove 42 is opened inside the guide post 41. A T-shaped rod 43 is fixedly installed on the bottom of the filter plate 31. The T-shaped rod 43 is slidably installed inside the guide post 41. By setting the guide post 41 on the inner bottom of the nozzle body 1, when the filter plate 31 moves downward due to blockage, the guide post 41 provides axial sliding guidance for the filter plate 31. The compression spring 44 provides the reset force to ensure that the filter plate 31 moves up and down smoothly. A compression spring 44 is fixedly installed on the bottom of the T-shaped rod 43. The drive rod 508 is rotatably installed inside the T-shaped rod 43. When the filter plate 31 moves downward, the high-pressure coolant is discharged through the water outlet 501. This not only provides a power basis for the self-cleaning structure at the upper end of the filter plate 31, but also allows the coolant to be discharged in a positive direction. The system continuously discharges heat to cool the battery box, achieving a dual function of self-cleaning power supply and emergency cooling. This avoids filter clogging leading to cooling failure and ensures that the battery box maintains heat dissipation during the cleaning process of the filter plate 31. The inner wall of the movable sleeve 507 has a cross-shaped groove, and the upper end of the compensating rod 506 is slidably installed in the cross-shaped groove on the inner wall of the movable sleeve 507. When the filter plate 31 moves up and down, the movable sleeve 507 slides along the axial direction of the compensating rod 506. The cross-shaped groove restricts the circumferential rotation of the movable sleeve 507 and the compensating rod 506, so that the drive rod 508 can still maintain transmission with the rotating rod 505 during the movement of the filter plate 31. This ensures that the scraper 510 always follows the rotation of the ring plate 502 to continuously clean the filter plate 31, guaranteeing the continuity and reliability of the self-cleaning function.

[0032] Please see Figures 1-3 A baffle plate 32 is fixedly installed at the bottom of the filter plate 31. The position of the baffle plate 32 corresponds to the position of multiple water outlets 501. When the filter plate 31 is blocked and moves downward by the impact of the liquid, the water outlets 501 are located at the upper edge of the filter plate 31. The liquid is discharged from the multiple water outlets 501. The axial position of the water outlets 501 matches the axial height of the drive plate 503. The spray direction of the multiple water outlets 501 is tangentially corresponding to the impact surface of the drive plate 503 at the corresponding position. This allows the coolant to directly act on the force area of ​​the drive plate 503 after being sprayed out, efficiently driving the drive plate 503 to drive the ring plate 502 to rotate, converting the kinetic energy of the water into rotational torque. Then, through the transmission structure, the scraper 510 continuously scrapes the filter plate 31 at a suitable speed.

[0033] Please see Figures 3-5The inner wall of the nozzle body 1 is provided with multiple slide rails 33. Multiple sliders 34 that are compatible with the slide rails 33 are fixedly installed on the side circumferentially of the filter plate 31. The sliders 34 are slidably installed inside the slide rails 33 to provide precise guidance for the filter plate 31, prevent it from tilting or shifting, ensure the sealing performance between the filter plate 31 and the nozzle body 1, and reduce the moving resistance. A sealed bearing is provided at the rotating connection between the rotating rod 505 and the bottom of the nozzle body 1. The upper and lower ends of the drive rod 508 located outside the T-shaped rod 43 are provided with limiting protrusions. The limiting protrusions are annular plates to ensure that the drive rod 508 can be normally transmitted inside the T-shaped rod 43 and to limit the axial movement of the drive rod 508. A threaded joint 2 is fixedly installed at the upper end of the nozzle body 1, and multiple nozzles 6 are evenly fixedly installed at the bottom of the nozzle body 1.

[0034] Working principle: In actual application, the nozzle body 1 is first connected to the high-pressure coolant flow pipe through the threaded joint 2. The coolant flows in from the threaded joint 2 at the top of the nozzle body 1, is filtered by the filter plate 31, and is sprayed out from the nozzle 6 at the bottom to cool the long curved tube battery box.

[0035] When the filter plate 31 becomes clogged due to the accumulation of impurities from long-term use, the pressure of the coolant above the filter plate 31 increases, and the liquid force pushes the filter plate 31 downward, compressing the compression spring 44 at the bottom. At this time, the baffle plate 32 at the bottom of the filter plate 31 no longer blocks the water outlet 501, and the high-pressure coolant is sprayed out from the water outlet 501 at the bottom of the nozzle body 1. The sprayed coolant impacts the drive plate 503 on the inner wall of the ring plate 502, and the drive ring plate 502 drives the connecting plate 504 and the rotating rod 505 to rotate. The rotating rod 505 drives the drive rod 508 to rotate through the compensation rod 506 and the movable sleeve 507. The limiting plate 509 and the scraper 510 at the upper end of the drive rod 508 rotate accordingly. The scraper 510 continuously scrapes the upper surface of the filter plate 31 to remove the attached impurities, thus achieving self-cleaning of the filter plate 31.

[0036] Meanwhile, as the filter plate 31 moves downward, the T-shaped rod 43 slides in the groove 42 of the guide post 41. The guide post 41 provides axial guidance for the filter plate 31, and the compression spring 44 provides reset force to ensure that the filter plate 31 moves smoothly. After the impurities on the filter plate 31 are cleared, the compression spring 44 pushes the filter plate 31 to reset, the baffle plate 32 blocks the water outlet hole 501 again, and the coolant resumes normal spraying from the nozzle 6.
