Intelligent energy storage system thermal management device

Abstract

This invention provides a thermal management device for a smart energy storage system. Its structure includes: a base, a smart host, a circulating water tank, circulating pipes, and a heat exchange structure. The position of the smart host is determined at the upper end of the base. The improved heat exchange structure allows the cooling frame to completely cover the battery pack using a covering groove, with both ends sealed by a sealing structure. This isolates the battery pack from the outside environment, enabling the cooling frame and heating module to precisely control the battery pack temperature, preventing rapid temperature changes due to external factors. It also protects the battery pack casing. Furthermore, the fixing grooves and clips on the heating body allow the PCT heating element to be fixed at its origin using inserts and reinforcing rods, replacing the original adhesive assembly. This avoids issues such as delamination and prevents the PCT heating element from falling off during battery pack disassembly or installation.

Description

Technical Field

[0001] This invention relates to the field of battery temperature control technology, and more specifically to a thermal management device for a smart energy storage system. Background Technology

[0002] The intelligent energy storage system thermal management device is an intelligent temperature control system that can automatically control temperature, uniformly dissipate heat, preheat at low temperatures, or provide early warnings at high temperatures. It controls the battery temperature within the range of 15℃-35℃, preventing the battery from catching fire due to overheating or experiencing degradation due to low temperatures, thus improving the battery's safety factor and reducing energy consumption degradation. Therefore, the use of the thermal management device can effectively improve the battery's utilization rate and the safety factor of electricity use. In summary, the inventors have found that existing thermal management devices have the following main defects: After the current thermal management device is connected to the battery pack, one end of the battery pack is tightly attached to the heat exchange plate. Therefore, the current device cannot completely cover and control the temperature of the battery pack. As a result, the temperature is affected by external factors and rapid temperature changes in a short period of time, making it difficult to keep the temperature within a suitable range for a long time. In addition, the battery pack is in direct contact with the space, which can cause the outer shell to age rapidly. Therefore, the actual performance of the current device is reduced.

[0010] As a further improvement of the present invention, the sealing structure is provided with a slider, the slider is disposed at the center of the edge of the slide frame and a solid plate is mounted inside the slide frame, and an insulating layer is provided on the surface of the solid plate.

[0011] As a further improvement of the present invention, the slider is provided at the upper and lower center positions of the slide frame and is set in a symmetrical orientation. The slide frame covers the edge of the solid plate, and the solid plate contacts the battery pack inside the encapsulation groove through the insulating layer.

[0012] As a further improvement of the present invention, a connecting block is provided at the outer center of the solid plate. The connecting block has a locking groove at its center and the locking groove is adapted to a locking bolt. One end of the locking bolt is connected to a sliding rod, which is embedded inside the main rod. The other end of the main rod is connected to a control block.

[0013] As a further improvement of the present invention, the locking groove and locking bolt of the connecting block are both circular in shape, and the slide rod is locked or disassembled with the connecting block by the control of the locking bolt and the main rod.

[0019] 2. With the improvement of the heating module, the PCT heating element can be fixed at the origin using the fixing groove and clamp on the heating body, replacing the original adhesive assembly. This avoids situations such as delamination and also prevents the PCT heating element from falling off during battery pack disassembly or installation.

[0020] 3. With the improved sealing structure, the solid plate can directly contact the edge of the battery pack through the insulating layer by the cooperation of the slider and the sliding frame. This allows the battery pack to be disassembled and detached from the covering groove. The process can be achieved by linear pushing using the cooperation of the main rod and the sliding rod, thus improving the convenience of disassembly. After use, the sliding rod can detach from the connecting block and retract into the main rod for easy storage.

[0021] 4. With the improvement of the anti-leakage component, the restraining block on the balance block can restrain the inner wall of the circulation pipe. At the same time, the magnetic suction plate and protrusion on the balance block can forcibly and precisely restrain one end of the circulation pipe, avoiding the appearance of gaps. Therefore, it can improve the airtightness of the coolant flow and prevent external leakage. In addition, the splicing pipe at the lower end of the balance block can improve the connection effect with the inside of the cooling frame through the rebound block. The rebound block has the effect of eliminating gaps, which can further improve the airtightness of the overall coolant circulation. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 5 As shown: This invention provides a thermal management device for a smart energy storage system. Its structure includes: a base 1, a smart host 2, a circulating water tank 3, a circulating pipe 4, and a heat exchange structure 5. The position of the smart host 2 is determined at the upper end of the base 1. Then, the smart host 2 controls the circulating water tank 3 to allow the coolant to enter the position of the heat exchange structure 5 through the circulating pipe 4. The heat exchange structure 5 surrounds and covers the battery pack.

[0031] The heat exchange structure 5 includes a leak-proof component 51, a cooling frame 52, a covering groove 53, a heating module 54, a limiting rail 55, a sensing module 56, and a sealing structure 57. The leak-proof component 51 is connected to the pipeline provided in the cooling frame 52, but is not connected to the covering groove 53. The covering groove 53 positions the battery pack through the heating module 54 and the limiting rail 55. The sensing module 56 provided on the edge of the cooling frame 52 is in contact with the battery pack. The two ends of the cooling frame 52 are closed by the sealing structure 57.

[0032] In this process, the cooling frame 52 is connected to the circulation pipe 4 through the leak-proof component 51 of the heat exchange structure 5. Then, the cooling frame 52 covers the battery pack in all directions through the covering groove 53, allowing the heating module 54, the sensing module 56 to come into contact with the battery pack. The sealing structure 57 then helps to install or remove the battery pack.

[0033] The base 1 is arranged in a parallel configuration, which keeps the smart host 2, the circulating water tank 3, and the heat exchange structure 5 in a vertical position. The circulating water tank 3 includes a water pump that guides the coolant.

[0034] The leak-proof component 51 is airtightly connected to one end of the circulation pipe 4. The cooling frame 52 determines the position of the heating module 54 and the limiting rail 55 through the covering groove 53. The limiting rail 55 is generated at the distance of the heating module 54. The sensing module 56 detects the temperature, humidity and pressure inside the covering groove 53 and then transmits data wirelessly with the intelligent host 2. The sealing structure 57 is provided in two sets and is symmetrically arranged at both ends of the cooling frame 52 through the covering groove 53.

[0035] The heating module 54 is provided with a heating body 541. The heating body 541 is provided with a PCT heating element 542 on its edge. The PCT heating element 542 is connected to an insert 543. A reinforcing rod 544 is provided at the lower end of the insert 543. A fixing groove 545 is opened on the edge of the heating body 541 to allow the insert 543 to be embedded. A clip 546 is provided at the lower end of the fixing groove 545 to allow the reinforcing rod 544 to be inserted.

[0036] The edge of the heating body 541 is connected to the inside of the covering groove 53 through the PCT heating plate 542, and the insert 543 and the reinforcing rod 544 are perpendicular to each other and embedded in the fixing groove 545 and the jacket 546.

[0037] The sealing structure 57 is provided with a slider 571, which is located at the center of the edge of the slide frame 572 and a solid plate 573 is mounted inside the slide frame 572. An insulating layer 574 is provided on the surface of the solid plate 573.

[0038] The slider 571 is provided at the upper and lower center positions of the slide frame 572 and is set in a symmetrical orientation. The slide frame 572 covers the edge of the solid plate 573, and the solid plate 573 contacts the battery pack inside the covering groove 53 through the insulating layer 574.

[0039] The solid plate 573 is further provided with a connecting block 5731 at its outer center. The connecting block 5731 has a locking groove 5732 at its center and the locking groove 5732 is adapted to a locking bolt 5733. One end of the locking bolt 5733 is connected to a sliding rod 5734, which is embedded in the main rod 5735. The other end of the main rod 5735 is connected to a control block 5736.

[0040] The locking groove 5732 and locking bolt 5733 of the connecting block 5731 are both circular, and the slide rod 5734 is locked or disassembled with the connecting block 5731 by the control of the locking bolt 5733 and the main rod 5734. The connecting block 5731 is welded to the outer center of the solid plate 573.

[0041] The specific functions and operation procedures of this embodiment are as follows: In this invention, the base 1 of the intelligent energy storage system thermal management device determines the positions of the intelligent host 2 and the circulating water tank 3. The circulating water tank 3 is then connected to the circulating pipe 4 and the heat exchange structure 5 to cool the internal battery pack. Simultaneously, the intelligent host 2 works in conjunction with the sensing module 56 within the heat exchange structure 5. The sensing module 56 monitors the temperature, humidity, and pressure inside the covering groove 53 of the heat exchange structure 5 in real time, enabling the intelligent host 2 to control the heating module 54 or the cooling frame 52. Furthermore, the intelligent host 2 features real-time sensing: densely packed temperature / voltage / humidity sensors collect data in milliseconds; AI predictive control: algorithms predict thermal changes in advance, pre-cooling / pre-heating to avoid large temperature fluctuations; and cloud-based control. Edge computing enables remote monitoring, fault early warning, and data analysis, supporting unattended operation and maintenance, thus achieving the effect of a smart system. The cooling frame 52 of the heat exchange structure 5 is connected to the circulation pipe 4 via the leak-proof component 51, allowing the water pump in the circulating water tank 3 to effectively guide the internal coolant. The cooling frame 52, based on the tank shape and internal covering groove 53, can cover the edge of the battery pack while positioning the heating module 54 and sensing module 56, ensuring effective contact with the battery pack. Finally, a sealing structure... By closing both ends of structure 57, the uncontrollable temperature and humidity caused by rapid temperature changes due to external factors can be avoided. This improves the device's performance and protects the battery pack's external characteristics, preventing rapid aging caused by continuous external exposure. The heating module 541 of the heating module 54 allows the insertion block 543 and reinforcing rod 544 of the PCT heating element 542 to be inserted through the fixing slot 545 and the clamp 546. After the insertion block 543 and reinforcing rod 544 are embedded in the fixing slot 545 and the clamp 546, the PCT heating element... The heating element 542 is positioned at the edge of the heating body 541, replacing the original adhesive and preventing subsequent detachment. It also prevents the battery pack from separating from the heating body 541 during disassembly, thus improving the stability of the heating module 54 and indirectly increasing the strength of the device. Subsequently, the sliding frame 572 of the sealing structure 57 can be adapted to the shape of the covering groove 53 via the edge slider 571. After the battery pack is assembled, it can contact the insulating layer 574, preventing issues after the channel is closed. Conversely, when the battery pack is removed from the cover slot 53, the locking bolt 5733 of the slide rod 5734 can be locked through the locking slot 5732 of the connecting block 5731 outside the solid plate 573. Then the main rod 5735 of the slide rod 5734 can be extended, and finally the control block 5736 is used to push it linearly. Therefore, the removal efficiency of the battery pack from the cover slot 53 is improved. When pushing it out, the battery pack needs to be powered off and disconnected from the circuits such as the sensing module 56, so the safety factor of the removal can be ensured.

[0042] Example 2: Figures 6 to 7 As shown: This invention provides a thermal management device for a smart energy storage system. Its structure includes a balance block 511 provided in the anti-leakage component 51, a restraining block 512 provided at the center of the upper end of the balance block 511, a flow groove 513 opened at the center of the restraining block 512, a splicing pipe 514 mounted at the lower end of the balance block 511, and a rebound block 515 connected to the lower edge of the splicing pipe 514.

[0043] The balance block 511 and the restraining block 512 are perpendicular to each other. The flow groove 513 of the restraining block 512 is opened vertically and passes through the center of the splicing pipe 514. The rebound block 515 of the splicing pipe 514 is made of rubber.

[0044] The balance block 511 also includes a block body 5111, and a magnetic suction plate 5112 is provided on the surface of the block body 5111. The corners of the magnetic suction plate 5112 are provided with protrusions 5113.

[0045] The block 5111 and the magnetic plate 5112 are parallel to each other and are connected to one end of the circulation pipe 4 in a parallel, airtight manner through the protrusion 5113. The magnetic plate 5112 and the edge of one end of the circulation pipe 4 are in contact with each other and are attracted and restrained.

[0046] The specific functions and operation procedures of this embodiment are as follows: In this invention, the balance block 511 of the anti-leakage component 51 can restrain the interior of one end of the circulation pipe 4 through the restraining block 512, and then allow the coolant to flow through the flow groove 513. Furthermore, the splicing pipe 514 at the lower end of the balance block 511 can be combined with the rebound block 515 to improve the airtightness of the connection with the interior of the cooling frame 52. Through the rebound effect of the rebound block 515, the gap elimination characteristic can be achieved. At the same time, the block body 5111 of the balance block 511 can be seamlessly and precisely connected to one end of the circulation pipe 4 through the magnetic suction plate 5112 and the protrusion 5113. The seamless splicing of the upper and lower ends can improve the flow stability of the coolant, avoid leakage caused by gaps, and ensure the safety factor and heat exchange stability of the actual use of the device.
