Description

Technical Field

[0001] The present invention relates to the technical field of battery protection boards, and particularly relates to an energy storage battery protection board integrated with a radiator. Background Art

[0002] With the rapid development of the renewable energy and electric vehicle markets, energy storage battery systems play an increasingly important role in energy storage and power supply. To ensure the safety and reliability of energy storage batteries, battery protection boards are widely used in battery management systems to continuously monitor the status of batteries and perform real-time management.

[0003] In high-current charge and discharge scenarios, the protection board needs to frequently monitor parameters such as the voltage, current, and temperature of the battery and make quick responses based on these parameters. This high-frequency monitoring and response will increase the workload of the protection board, causing its own temperature to rise; in addition, a large amount of heat is generated during the charge and discharge process of energy storage batteries. If this heat cannot be dissipated in a timely and effective manner, it will cause the battery temperature to rise. Excessive battery temperature will not only affect the performance and lifespan of the battery, but may also trigger serious safety problems such as thermal runaway.

[0004] Currently, energy storage battery protection boards on the market usually integrate radiators, but most of these radiators adopt a design with a fixed heat dissipation capacity and cannot dynamically adjust the cooling capacity according to the real-time temperature. Radiators with a fixed heat dissipation capacity will cause resource waste in low-load or low-temperature environments, and may not be able to provide sufficient heat dissipation effects in high-load or high-temperature environments.

[0032] The present invention will be further described in conjunction with the following embodiments.

[0033] As Figures 1 to 7 it can be seen, an energy storage battery protection board with an integrated radiator described in this embodiment includes a circuit board 1 and a radiator disposed on the top of the circuit board 1; the radiator includes a bottom plate 2, a liquid cooling pipe 21, a pumping box 3 and a cold water tank 22; the liquid cooling pipe 21, the pumping box 3 and the cold water tank 22 are all disposed on the bottom plate 2;

[0034] the liquid cooling pipe 21, the pumping box 3 and the cold water tank 22 are in communication with each other; a pumping assembly is disposed in the pumping box 3; a machine base 4 is disposed on the bottom plate 2; a pressing rod 41 is movably disposed on the machine base 4 in a lifting manner; the pressing rod 41 is used to drive the pumping assembly to move;

[0035] the machine base 4 is provided with a sliding seat 5 that slides along the length direction; the sliding seat 5 is provided with a driving frame 6 that moves up and down to drive the pressing rod 41 to move up and down; a limiting groove is provided on the side wall of the machine base 4; the driving frame 6 is movably disposed in the limiting groove; the limiting groove includes a plurality of first deformation grooves 7 and second deformation grooves 8 that are alternately connected in sequence along the length direction of the machine base 4; the first deformation groove 7 is inclined upward; the second deformation groove 8 is inclined downward; the machine base 4 is provided with a driving member 52 for driving the sliding seat 5 to slide. Among them, the driving member 52 can be a linear module, a cylinder, an oil cylinder or an electric cylinder, etc.

[0036] Specifically, for the energy storage battery protection board with an integrated radiator described in this embodiment, when the energy storage battery is working, the electronic components on the circuit board 1 generate heat, and the heat generated by the electronic components is dissipated through the radiator.

[0037] During the operation of the radiator, the sliding seat 5 is driven by the driving member 52 to slide along the length direction of the machine base 4. During the sliding of the sliding seat 5, the driving frame 6 is driven by the sliding seat 5 to move along the limiting groove, so that the driving frame 6 alternately moves between the first deformation groove 7 and the second deformation groove 8, thereby enabling the driving frame 6 to continuously rise and fall on the sliding seat 5. During the rising and falling of the driving frame 6, the pressure rod 41 is driven to rise and fall, thereby driving the pumping and conveying assembly to move, so that the coolant flows between the liquid cooling pipe 21, the pumping box 3 and the cold water tank 22, accelerating the heat dissipation speed of the circuit board 1.

[0038] When the temperature of the circuit board 1 is relatively high, the first deformation groove 7 and the second deformation groove 8 are deformed, thereby changing the peak position and valley position of the limiting groove, and being able to change the lifting amount of the driving frame 6 and the pressure rod 41, so that the cold water pumping amount and rate of the pumping box 3 can be changed, further accelerating the cooling of the circuit board 1.

[0039] In this embodiment, the first deformation groove 7 and the second deformation groove 8 can be deformed according to the temperature of the circuit board 1, thereby changing the peak position and valley position of the limiting groove, changing the lifting amount of the driving frame 6 and the pressure rod 41, so that the cold water pumping amount and rate of the pumping box 3 can be changed, and finally being able to cool according to the temperature of the circuit board 1, avoiding unnecessary energy consumption and overcooling.

[0041] Specifically, when the compression rod 41 drives the connecting rod 35, the upper piston 33, and the lower piston 34 to move upward, the coolant in the upper cavity 31 flows into the liquid cooling pipe 21 through the first one-way valve 23. The coolant in the liquid cooling pipe 21 flows into the cold water tank 22 through the second one-way valve 24, and the coolant in the cold water tank 22 enters the lower cavity 32 through the third one-way valve 25.

[0042] When the compression rod 41 drives the connecting rod 35, the upper piston 33, and the lower piston 34 to move upward, the coolant in the lower cavity 32 enters the upper cavity 31 through the connecting rod 35 and the fourth one-way valve 26, thereby driving the next pumping.

[0043] For an energy storage battery protection board integrated with a radiator according to this embodiment, the middle part of the liquid cooling pipe 21 is arranged in a meandering shape at the bottom of the bottom plate 2. Through the above setting, the circuit board 1 can be effectively cooled by heat dissipation.

[0044] For an energy storage battery protection board integrated with a radiator according to this embodiment, the bottom plate 2 is provided with a plurality of heat dissipation fins 27; the heat dissipation fins 27 are arranged above the middle part of the liquid cooling pipe 21. Through the above setting, the circuit board 1 can be effectively cooled by heat dissipation.

[0045] For an energy storage battery protection board integrated with a radiator according to this embodiment, a brush 51 is provided at the bottom of the sliding seat 5; the brush 51 abuts against the heat dissipation fins 27.
