Description

Technical Field

[0001] This application relates to the field of energy storage device technology, and in particular to a modular air-cooled heat dissipation structure for a grid-type energy storage device. Background Technology

[0002] Grid-based energy storage devices, as key supporting equipment in new power systems, play an increasingly important role in grid frequency regulation, peak shaving, and renewable energy grid integration. During operation, these devices generate significant heat from their power modules and cells. Failure to dissipate this heat effectively and promptly will lead to increased device temperature, decreased efficiency, and shortened lifespan, potentially even causing thermal runaway. Therefore, designing efficient and reliable heat dissipation structures is crucial for ensuring the safe and stable operation of grid-based energy storage devices.

[0003] Currently, mainstream heat dissipation solutions include air cooling, liquid cooling, and a combination of both. Pure air cooling is simple in structure and low in cost, but its heat dissipation capacity is limited, making it difficult to meet the heat dissipation requirements of high-power-density energy storage devices. Pure liquid cooling is highly efficient, but the system is complex, carries the risk of leakage, and is expensive. Therefore, some existing technologies have proposed a composite heat dissipation structure of "water cooling and air cooling." This involves first using a water cooling system to remove heat from the surface of the energy storage device, and then using forced convection air generated by a fan to provide secondary cooling to the heat exchange components of the water cooling system, aiming to achieve a balance between heat dissipation efficiency and system complexity. For example, patent document CN224123392U discloses a heat dissipation structure for an energy storage device.

[0004] However, this application still has the following problems: the fan assembly lacks an effective protection mechanism and has poor operational reliability. In the composite heat dissipation structure, the fan often needs to work with the moving component to achieve reciprocating airflow in order to expand the heat dissipation coverage. However, the fan impeller will vibrate when rotating at high speed, and the movement process is prone to introducing external impacts, which leads to a reduction in the transmission accuracy of the moving device. Furthermore, the fan lacks a locking mechanism when it is in the working position or in the stopped state, which causes it to be displaced under the action of external force or its own vibration, further aggravating the vibration and noise problems. Therefore, a modular air-cooled heat dissipation structure for a grid-type energy storage device is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies and avoid the impact of vibration during fan operation, this application provides a modular air-cooled heat dissipation structure for a grid-type energy storage device.

[0035] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0036] This application discloses a modular air-cooled heat dissipation structure for a grid-type energy storage device. The heat dissipation structure includes a water-cooled structure 2 and a heat dissipation device 3 installed on the energy storage device 1. The heat dissipation device 3 mainly includes a mounting shell 31, a movable component 34 disposed on the mounting shell 31, and a heat dissipation component 35.

[0037] It should be noted that the water-cooled structure 2 adopts the existing mature liquid cooling circulation technology. It has a circulation channel inside, and the heat generated during the operation of the energy storage device 1 is quickly removed through the forced circulation of the coolant. The water-cooled structure 2 is closely attached to the outer shell surface of the energy storage device 1 to ensure the maximum heat exchange area and provide a good heat pretreatment basis for subsequent air cooling.

[0038] In this embodiment, the mounting shell 31 is made of aluminum alloy, which has good thermal conductivity and lightweight advantages. The mounting shell 31 has a mounting groove 33 inside. Specifically, the heat dissipation component 35 is located in the mounting groove 33. A ventilation plate 32 is installed on the side of the mounting shell 31 near the energy storage device 1. Several ventilation holes are evenly opened on the ventilation plate 32 to facilitate airflow and full contact and heat exchange with the heat discharged from the water-cooled structure 2. A cover plate 36 is detachably installed on the top side of the mounting shell 31. The cover plate 36 is connected to the top edge of the mounting shell 31 by bolts to facilitate the maintenance and repair of the internal heat dissipation component 35 in the future.

[0039] The moving component 34 includes a drive motor 341, a lead screw 342, and a nut seat 345. The lead screw 342 passes through the interior of the mounting groove 33 and is rotatably mounted on the inner walls of both sides of the mounting groove 33 via bearing seats. The output shaft of the drive motor 341 and the end of the lead screw 342 are provided with a transmission component 343. The transmission component 343 is a transmission mechanism composed of a worm gear and a worm, which ensures smooth transmission without slippage. The nut seat 345 is threadedly connected to the lead screw 342, and the nut seat 345 is fixedly connected to the bottom side of the mounting cylinder 351 by bolts. A guide rail 344 is installed on the bottom wall of the mounting groove 33 to limit the movement of the nut seat 345. The guide rail 344 is a T-shaped guide rail, which cooperates with the T-shaped slider at the bottom of the nut seat 345 to ensure the stability and accuracy of the nut seat 345 when it makes linear reciprocating motion along the axial direction of the lead screw 342.

[0040] The heat dissipation assembly 35 includes a hollow mounting cylinder 351, a second drive motor 352, a transmission shaft 353, and an impeller 354. The mounting cylinder 351 has a sliding port 3511 that communicates with the outside. The sliding port 3511 extends along the axial direction of the mounting cylinder 351. A support base 37 is fixed inside the mounting cylinder 351. The support base 37 is made of stainless steel and has good corrosion resistance and structural strength. The transmission shaft 353 is connected to the support base 37 through bearings to ensure coaxiality and low friction loss when the transmission shaft 353 rotates at high speed. The two ends of the transmission shaft 353 are respectively connected and fixed to the output shaft of the second drive motor 352 and the outer wall of the impeller 354 through keys. The impeller 354 is a centrifugal axial flow impeller. The blade angle has been optimized by CFD fluid simulation to ensure that it can generate a large flow rate and low noise air cooling airflow when rotating at high speed.

[0041] The second drive motor, 352, is a brushless DC motor. Its speed can be adjusted by the controller according to the heat generated by the energy storage device 1, so as to achieve heat dissipation on demand and reduce energy consumption.

[0042] To address the issue of impeller 354 easily vibrating and shifting or even colliding with mounting cylinder 351 at high speeds, a protection mechanism 4 is installed inside mounting cylinder 351 to protect impeller 354 during operation. The protection mechanism 4 includes a linkage component 41, a clamping component 42, and a locking component 43. The linkage component 41 drives the clamping component 42 and the locking component 43 respectively to perform protection work in a transmission cooperation with the drive shaft 353. The mounting housing 31 is also provided with a locking strip 5 that engages with the locking component 43. The locking strip 5 consists of two parallel metal strips with teeth, which are fixed to the corresponding positions on the inner wall of the mounting housing 31 by rivets.

[0043] To further provide stable transmission, the clamping assembly 42 includes an elastic contact block 421 and a compression sleeve 422. There are three elastic contact blocks 421, and the three elastic contact blocks 421 are equidistantly installed on the outer wall of the support base 37. The included angles between the three elastic contact blocks 421 are equidistantly distributed to ensure that the clamping force on the outer wall of the transmission shaft 353 is evenly distributed. The elastic contact block 421 adopts a composite structure of rubber and spring steel sheet, with a stainless steel wear-resistant layer on the inner side and a high-elasticity rubber layer on the outer side, which has good elastic recovery performance and wear resistance. At the same time, multiple balls are provided on the contact side to ensure stable transmission of the transmission shaft 353. It should be noted that the extrusion sleeve 422 is hollow inside and is fitted on the outside of the three elastic bonding blocks 421. The inner side of the extrusion sleeve 422 and the outer side of the elastic bonding blocks 421 are provided with extrusion inclined surfaces 423 for abutting cooperation. The inclination angle of the extrusion inclined surfaces 423 is 15°-25°. When the extrusion sleeve 422 moves axially, the wedge-shaped extrusion force generated between the extrusion inclined surfaces 423 pushes the elastic bonding blocks 421 to contract radially toward the center, so that the inner side of the elastic bonding blocks 421 is tightly attached to the outer wall of the drive shaft 353, thus preventing the impeller 354 from being damaged due to abnormal vibration, external force collision or misoperation after the equipment stops.

[0044] To further provide stable transmission, the locking element 43 is connected to the linkage assembly 41 and the clamping assembly 42 respectively. There are two locking elements 43 and two locking bars 5, and the two locking elements 43 and the two locking bars 5 are distributed vertically on both sides of the mounting cylinder 351 to form a double lock and improve the locking reliability.

[0045] In this embodiment, the locking member 43 includes an L-shaped rod 431, on which a locking block 432 and a connecting block 434 are respectively installed. The locking block 432 is located at the end of the L-shaped rod 431, and the end of the locking block 432 is provided with a barb structure to form an interference fit with the locking strip 5. The locking surface of the locking block 432 is provided with an anti-disengagement slope to ensure that it is not easy to disengage after locking. The connecting block 434 is located on the outer wall of the L-shaped rod 431 and is fixedly connected to the outer wall of the compression sleeve 422 by screws. The end of the L-shaped rod 431 away from the locking block 432 extends through the slide 3511 and into the interior of the mounting cylinder 351. A guide rod 433 is installed inside the slide 3511. The guide rod 433 passes through the interior of the L-shaped rod 431 and the connecting block 434. The guide rod 433 guides and limits the movement of the L-shaped rod 431 to prevent the L-shaped rod 431 from deflecting or rotating during movement.

[0046] In this embodiment, the linkage component 41 includes a functional seat 411 rotatably mounted on one side of the support base 37, a rotor 412 fixed to the outer surface of the transmission shaft 353, a sliding sleeve 414 sleeved on the outer surface of the transmission shaft 353, and an abutment block 413 slidably disposed inside the rotor 412. A connecting rod 416 is provided between the abutment block 413 and the sliding sleeve 414. When the rotational speed of the transmission shaft 353 exceeds a preset threshold, the abutment block 413 is radially thrown out from the receiving groove 415 of the rotor 412 under the action of centrifugal force, abutting against the inner sidewall of the functional seat 411, and simultaneously pushing the sliding sleeve 414 to move axially along the transmission shaft 353 through the connecting rod 416.

[0047] The interior of the functional seat 411 is U-shaped, and the rotor 412 is located inside the functional seat 411. The outer side of the abutment block 413 is adapted to the inner side of the functional seat 411. The rotor 412 has a storage groove 415 for the extension and retraction of the abutment block 413. The storage groove 415 is opened radially along the rotor 412. When the drive shaft 353 is stationary or running at low speed, the abutment block 413 retracts into the storage groove 415 under the elastic force of the return spring 417. When the drive shaft 353 runs at high speed, the abutment block 413 extends out of the storage groove 415 under the action of centrifugal force, overcoming the spring force, and abuts against the U-shaped inner wall of the functional seat 411. Specifically, a buffer spring connected to the end of the drive shaft 353 is installed in the storage groove 415. It should be noted that the functional seat 411 can be used as a reserved transmission function. When the speed of the transmission shaft 353 exceeds the preset threshold, the abutment block 413 is radially thrown out from the receiving groove (415) of the rotor 412 under the action of centrifugal force and abuts against the inner wall of the functional seat 411. The functional seat 411 can rotate and thus perform the transmission function.

[0048] It should be noted that the sliding sleeve 414 consists of two rotatably connected collars, which are hinged together by a pin, allowing the sliding sleeve 414 to make slight angle adjustments while moving axially. The L-shaped rod 431 is fixed to the outer wall of one of the collars by welding. The other collar in the sliding sleeve 414 is rotatably mounted with a return spring 417 between it and the rotor 412. The return spring 417 is a helical compression spring, with one end abutting against the outer wall of the collar and the other end abutting against the end face of the rotor 412. When the impeller 354 stops running and the speed of the drive shaft 353 decreases, the abutment block 413 retracts into the receiving groove 415, and the return spring 417 drives the sliding sleeve 414 to reset, thereby driving the L-shaped rod 431 and the compression sleeve 422 back to the initial position. The elastic contact block 421 returns to the open state under its own elasticity and disengages from the outer wall of the drive shaft 353. The locking member 43 disengages from the locking strip 5, and the entire protection mechanism 4 returns to the standby state.

[0049] It is worth mentioning that this application achieves efficient heat dissipation of the grid-type energy storage device through the coordinated operation of the water-cooled structure 2 and the air-cooled heat dissipation device 3; the reciprocating movement of the heat dissipation component 35 driven by the moving component 34 expands the heat dissipation coverage and avoids the generation of local hot spots; the centrifugal trigger linkage setting of the protection mechanism 4 realizes automatic clamping stability and automatic locking fixation of the impeller 354 when it is running at high speed, without the need for additional electrical control drive, the structure is simple and reliable, the response speed is fast, effectively protects the operational safety of the impeller 354 and the heat dissipation component 35, extends the service life of the equipment, and improves the operational reliability of the entire energy storage system.

[0050] Combined with appendix Figure 1-9 The working principle of the above embodiments is as follows:

[0051] The heat generated during the operation of the energy storage device 1 is first exchanged through its surface with the water-cooled structure 2 to achieve initial heat removal; at the same time, the heat dissipation device 3 is activated, the drive motor 352 is powered on and rotates, driving the transmission shaft 353 to rotate. The transmission shaft 353 is fixedly connected to the impeller 354, which in turn drives the impeller 354 to rotate at high speed inside the mounting cylinder 351, generating a cooling airflow.

[0052] The airflow generated by the rotation of impeller 354 enters the mounting groove 33 through the ventilation plate 32 on one side of the mounting shell 31, and fully contacts the heat discharged by the water cooling structure 2, thus carrying away the heat. At the same time, the moving component 34 works synchronously. The drive motor 341 drives the lead screw 342 to rotate through the transmission component 343. The lead screw 342 is threadedly engaged with the nut seat 345, and the nut seat 345 moves linearly under the limiting action of the guide rail 344. The nut seat 345 is fixed to the bottom bolt of the mounting cylinder 351, thereby driving the entire heat dissipation component 35 to move back and forth along the mounting groove 33, so as to achieve uniform air cooling of the surface of the energy storage device 1, and improve the heat dissipation coverage and heat dissipation efficiency.

[0053] When the drive motor 352 drives the transmission shaft 353 to rotate, the rotor 412 on the surface of the transmission shaft 353 rotates synchronously. The abutment block 413 inside the rotor 412 extends out from the storage groove 415 under the action of centrifugal force and abuts against the inner side of the functional seat 411. The functional seat 411 is fixed to one side of the support seat 37, and the interior is U-shaped to fit the abutment block 413. When the abutment block 413 extends, it drives the sliding sleeve 414 to move axially along the transmission shaft 353 through the connecting rod 416. The sliding sleeve 414 is composed of two rotatingly connected collars. One of its collars is fixed to the L-shaped rod 431, thereby driving the L-shaped rod 431 to move along the sliding opening 3511.

[0054] When the L-shaped rod 431 moves, the connecting block 434 at one end drives the extrusion sleeve 422 to move synchronously. The inner side of the extrusion sleeve 422 abuts against the extrusion slope 423 on the outer side of the elastic fitting block 421. As the extrusion sleeve 422 moves, the extrusion slope 423 generates extrusion force, pushing the three elastic fitting blocks 421, which are equidistantly installed on the outer wall of the support base 37, to contract towards the center and tightly fit against the outer wall of the drive shaft 353. This provides a buffer and stabilizing effect on the drive shaft 353, preventing the impeller 354 from shifting or colliding due to vibration when the drive shaft 353 drives the impeller 354 to rotate at high speed. At the same time, the locking block 432 at the other end of the L-shaped rod 431 engages with the locking strip 5 on the mounting shell 31, locking and fixing the heat dissipation component 35 in the mounting groove 33, preventing the heat dissipation component 35 from shifting during operation, and further ensuring the safety of the impeller 354.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
