Technical Field

[0001] This invention relates to the field of secondary battery technology, specifically to a combined energy storage power supply with high-efficiency heat dissipation. Background Technology

[0002] With economic development, outdoor activities are becoming increasingly popular, and the demand for outdoor power equipment is also growing. The battery life of a power storage device depends on the capacity of its built-in secondary battery. Different scenarios require power supplies with different capacities, and the larger the battery capacity, the heavier the overall power supply and the more difficult it is to carry.

[0003] To overcome the above-mentioned defects, existing technology 1 (Chinese patent with announcement number CN222015599U, announcement date November 15, 2024) provides an outdoor combined energy storage power supply, including an energy storage power supply body. A moving device is provided on the lower surface of the energy storage power supply body. The moving device includes a square frame, which is fixedly connected to the lower surface of the energy storage power supply body. Two rotating rods are rotatably connected to the inner surface of the square frame. A square rod is fixedly connected to the arc surface of the rotating rod. Two universal wheels are fixedly connected to the surface of the square rod. Fixed rods are fixedly connected to both sides of the square frame. An operating panel is slidably connected to the arc surface of the fixed rod. Two insert rods are fixedly connected to the side of the operating panel near the square frame. The arc surfaces of both insert rods are slidably connected to the square frame. This solves the problem that when workers need to move the energy storage power supply body, the excessive weight of the energy storage power supply body makes it inconvenient for them to move it. Technique 2 (Chinese Patent No. CN218867312U, Publication Date: April 14, 2023) discloses a combined energy storage power supply, comprising a first battery module, an energy battery slidably connected inside the first battery module, a closing cover slidably connected inside the top of the first battery module, a protective pad provided inside the first battery module and at the bottom of the through hole, a second battery module mounted on top of the first battery module, a first connecting bolt slidably connected inside the second battery module, the bottom end of the first connecting bolt being threadedly connected to the closing cover, a third battery module mounted on top of the second battery module, a second connecting bolt slidably connected inside the third battery module, and through the cooperation of the first battery module, the second battery module, the third battery module and the cover, different functional assembly blocks can be assembled on the top of the first battery module as needed, the third battery module located on top can be protected by the cover, and the energy storage power supply can be moved by a pull strap.

[0004] Existing technologies improve the portability of energy storage power supplies by configuring casters or tethers. However, when using casters, if the operation is not proper, the energy storage power supply is prone to losing balance and tipping over. When using tethers, the high strength and durability of the tethers are required. Once the tethers break, the equipment is very likely to fall. In addition, the overall structure makes it easy for heat to accumulate on the battery surface, affecting the battery's working efficiency and lifespan.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing high-efficiency heat dissipation combined energy storage power supplies. Therefore, we propose a high-efficiency heat dissipation combined energy storage power supply that can effectively solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This highly efficient heat dissipation combined energy storage power supply makes it easy to move the power box quickly with the handle, greatly improving the portability of the device and solving the inconvenience of using casters and straps. The heat-conducting cover on the outside of the secondary battery can conduct heat to the heat dissipation plate on the side and the heat dissipation fins on the limiting frame, realizing rapid heat dissipation and multi-dimensional and close-range heat dissipation, thereby greatly improving the overall heat dissipation efficiency. The specific details are as follows:

[0017] (1) The handle can be used directly for the rapid movement of the power box, greatly reducing the difficulty of handling and debugging. It is convenient to flexibly adjust the installation position according to actual needs, significantly improving the portability of the device. After being moved into place, the first and second magnetic blocks on the side of the handle are magnetically attracted, which can effectively fix the handle and prevent it from shaking and causing noise or collision damage when idle.

[0018] (2) The thermally conductive support plate provides a stable installation base for the battery assembly, ensuring uniform force distribution and reducing the impact of vibration on internal components. The limiting frame precisely limits the secondary battery, preventing battery displacement and collision during device movement or operation, reducing the risk of damage, and ensuring stable power supply. The thermally conductive cover on the outside of the battery can initially conduct battery heat to the heat sink and heat fins, achieving rapid heat dissipation and preventing heat accumulation on the battery surface.

[0019] (3) When the internal temperature rises, the first motor is started, and its output simultaneously drives the first cooling fan to rotate and the first drive pump to run. The dual cooling modes are started synchronously through a single power source, reducing the number of power components. The dual modes act on the external environment of the battery at close range, achieving multi-dimensional efficient heat dissipation.

[0020] (4) The operator starts the second motor, which drives the second cooling fan and the second drive pump to run, forming a dual air cooling and secondary liquid cooling cycle. The dual air cooling greatly improves the air circulation speed and enhances the heat dissipation effect. The secondary liquid cooling increases the contact area with the heat-conducting support plate through the serpentine pipe, extracts heat from the bottom of the battery assembly, complements the original heat dissipation structure, and achieves all-round heat dissipation.

[0021] (5) The dual-axis motor is started by the dual mechanism of shape memory alloy deformation and magnetic adsorption triggering, which avoids the failure of a single trigger and the untimely heat dissipation, thus improving reliability. The dual-axis motor can simultaneously open multiple shields and open the second heat dissipation channel, greatly expanding the heat dissipation channel and heat exchange efficiency.

[0037] 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.

[0038] Example 1: In this example, the overall cooling system directly contacts the external environment of the secondary battery 4, achieving multi-dimensional and close-range heat dissipation, thereby greatly improving the overall heat dissipation efficiency. Figures 1-5The technical solution shown includes a power supply box 1, inside which a heat-conducting support plate 2 is installed. A battery assembly is mounted on the heat-conducting support plate 2. The battery assembly includes a limiting frame 3 mounted on the heat-conducting support plate 2, on which secondary batteries 4 are mounted. A heat-conducting cover 5 is fitted around the secondary batteries 4. The secondary batteries 4 are arranged in a matrix. A heat dissipation plate 6 is mounted on the limiting frame 3, located at the side of the heat-conducting cover 5. A heat sink 7 is mounted on the limiting frame 3. A heat dissipation assembly is installed inside the power supply box 1. The heat dissipation assembly includes a first motor 8 installed inside the power supply box 1. The output end of the first motor 8 is connected to a first cooling fan 9 and a first drive pump 10. The input end of the first drive pump 10 is connected to an external cooling structure through a first pipe 11. The output terminal 10 is connected to the inner cavity of the heat sink 6 via the second pipe 12, which is located at the bottom side of the heat sink 6. The inner cavity of the heat sink 6 is connected to the external support structure via the third pipe 13, which is located at the top side of the heat sink 6. A temperature sensor is installed inside the power supply box 1. The first motor 8 is electrically connected to the operator, and the temperature sensor is electrically connected to the operator. The power supply box 1 can be quickly moved by rotating the handle 20, which greatly improves the portability of the device and makes it easy to flexibly adjust the installation position according to actual use needs, reducing the difficulty of handling and debugging. After moving to the required position, rotating the handle 20 causes the first magnetic block 21 and the second magnetic block 24 on the side of the handle 20 to magnetically attract each other, making the handle 20 more stable and preventing the handle 20 from being idle. Shaking can cause noise or collision damage, improving the overall structure and safety of the device. It solves the inconvenience of using casters and straps. The heat-conducting support plate 2 supports the top battery assembly, and the limiting frame 3 in the battery assembly limits the secondary battery 4, effectively preventing displacement and collision during device movement or operation, reducing the risk of damage to the secondary battery 4, and ensuring power supply stability. The heat-conducting cover 5 on the outside of the secondary battery 4 can conduct heat to the heat dissipation plate 6 on the side and the heat dissipation fins 7 on the limiting frame 3, achieving rapid heat dissipation and preventing heat accumulation on the surface of the secondary battery 4, laying the foundation for subsequent efficient heat dissipation. When the internal temperature of the power box 1 rises, the temperature sensor transmits a signal to the operator, which starts the first motor 8. The output terminal 8 simultaneously drives the first cooling fan 9 to rotate and the first drive pump 10 to run. This achieves simultaneous start-up of air cooling and liquid cooling through a single power source, reducing the number of power components, lowering manufacturing costs and energy consumption, while ensuring timely heat dissipation response. The airflow generated by the first cooling fan 9 accelerates air circulation inside the power supply box 1, quickly carrying away hot air floating inside. The channels on the heat sink 6 contact the airflow, increasing the heat dissipation contact area and facilitating the flow of hot air through the first heat dissipation slot 19 on the surface of the power supply box 1, achieving initial air cooling. The first heat dissipation slot 19 is equipped with a dustproof mesh for easy dust prevention, effectively blocking external dust from entering the device and preventing dust from adhering to the surfaces of electronic components and heat dissipation structures, thus affecting heat dissipation performance and component lifespan.Simultaneously, the first drive pump 10 draws coolant from the external cooling structure through the first pipe 11, and delivers it to the inner cavity of the heat sink 6 through the second pipe 12 located at the bottom side of the heat sink 6. After absorbing the heat conducted by the secondary battery 4 within the heat sink 6, the coolant flows out through the third pipe 13 located at the top side of the heat sink 6 to the external receiving structure, completing the liquid cooling cycle. The overall cooling directly contacts the external environment of the secondary battery 4, achieving multi-dimensional and close-range heat dissipation, thereby greatly improving the overall heat dissipation efficiency. This quickly curbs the temperature rise, ensures the secondary battery 4 operates within a suitable temperature range, and extends battery life.

[0039] Example 2: In this example, the serpentine pipe 18 increases the contact area with the heat-conducting support plate 2, thereby improving heat absorption efficiency. Specifically, as follows... Figures 3-7 As shown, the following is disclosed: An auxiliary heat dissipation assembly is installed inside the power supply box 1. This assembly includes a second motor 14 installed inside the power supply box 1. The output of the second motor 14 is connected to a second cooling fan 15 and a second drive pump 16. A serpentine pipe 18 is installed inside the power supply box 1, located at the bottom of the heat-conducting support plate 2. The input of the second drive pump 16 is connected to an external cooling structure via a fourth pipe 17. The output of the second drive pump 16 is connected to one end of the serpentine pipe 18, and the other end of the serpentine pipe 18 is connected to an external receiving structure. A first heat dissipation groove 19 is formed on the surface of the power supply box 1. If the temperature continues to rise, the operator will further activate the second motor 14 of the auxiliary heat dissipation assembly to achieve graded adjustment of the heat dissipation power. This allows for precise matching of heat dissipation intensity according to temperature changes, avoiding unnecessary energy waste and improving the energy efficiency of the device. The output of the second motor 14 drives the second cooling fan 15 to rotate and the second drive pump... When the first cooling fan 9 is running, the second cooling fan 15 enhances the air cooling effect and flows out of the first cooling slot 19 together with the airflow generated by the first cooling fan 9. The dual air cooling airflow greatly improves the air circulation speed and enhances the heat dissipation effect. The dustproof screen set inside the first cooling slot 19 can continuously ensure the dustproof effect while enhancing heat dissipation, preventing dust from entering the device in large quantities with the strong airflow. The second drive pump 16 draws coolant from the external cooling structure through the fourth pipe 17 and delivers it to the serpentine pipe 18 located at the bottom of the heat-conducting support plate 2. The serpentine pipe 18 increases the contact area with the heat-conducting support plate 2 and improves the heat absorption efficiency. After the coolant absorbs the heat conducted by the heat-conducting support plate 2 in the serpentine pipe 18, it flows to the external receiving structure to form a secondary liquid cooling cycle, further drawing heat from the bottom of the battery assembly to achieve all-round heat dissipation and further improve heat dissipation efficiency. It can effectively cope with extreme high temperature conditions and prevent the secondary battery 4 from overheating and causing a safety accident.

[0040] Example 3: In this example, multiple baffles 28 open simultaneously, opening the top of the box cover and thus increasing the air exchange channel between the power supply box 1 and the outside air, significantly improving heat exchange efficiency. Specifically, as shown below... Figure 1 and Figures 8-14As shown, the following is disclosed: A lid is provided on the top of the power supply box 1, and a handle 20 is rotatably connected to the lid. A first magnet 21 is provided on the side of the handle 20. A starting assembly is provided on the lid, comprising a lifting member 22 and a passive structure 26 mounted on the lid. A first spring 23 is sleeved on the outside of the lifting member 22, and a second magnet 24 magnetically attracted to the first magnet 21 is mounted on the top of the lifting member 22. A contact 25 is mounted on the side of the lifting member 22, and the contact 25 is electrically connected to the operator. The passive structure 26 includes a storage box 2601 mounted on the lid. Inside the storage box 2601, a contact piece 2603 is connected via a shape memory alloy sheet 2602. The contact piece 2603 is electrically connected to the power-conducting structure and the operator via a wire. The lid is equipped with... There are auxiliary components, including a dual-axis motor 27 mounted on the cover, which is electrically connected to the operator. The first output end of the dual-axis motor 27 is connected to a rotating shaft, and a baffle plate 28 is mounted on the outside of the rotating shaft. The baffle plates 28 are equidistantly spaced. Gears 29 are mounted on the end of the rotating shaft, and adjacent gears 29 mesh with each other. A downward-sloping second heat dissipation groove 30 is provided on the side of the power supply box 1. A dust cover 31 is bolted to the outside of the power supply box 1 and is located outside the second heat dissipation groove 30. A cam 32 is connected to the second output end of the dual-axis motor 27. A conveyor cylinder 33 is mounted on the cover, and a piston 34 is connected through the inside of the conveyor cylinder 33. A second spring 35 is provided on the outside of the piston 34. A sleeve 37 is mounted on the heat-conducting support plate 2. A push rod 38 is movably connected inside the cylinder 37. The conveying cylinder 33 is connected to the inner cavity of the sleeve 37 through the conveying pipe 36. A third spring 39 is installed on the outside of the push rod 38. A baffle plate 40 is set on the top of the push rod 38. The baffle plate 40 is located on the side of the second heat dissipation groove 30. A through groove 41 is opened on the surface of the baffle plate 40. When the ambient temperature is low, the top cover of the device blocks the second heat dissipation groove 30 through the baffle plate 28. The through groove 41 on the surface of the baffle plate 40 is offset from the second heat dissipation groove 30 to reduce internal heat loss. This helps to maintain a suitable internal operating temperature of the device, reduce the risk of battery activity decline in low-temperature environments, and ensure the normal power supply performance of the device under low-temperature conditions. However, when the temperature reaches an extremely high value, the passive structure 26 changes, and the storage box 260... 1. The internal shape memory alloy sheet 2602 deforms, pushing the contact piece 2603 upward. At this time, because the first magnetic block 21 and the second magnetic block 24 of the handle 20 are completely magnetically attracted, the second magnetic block 24 will drive the lifting component 22 to compress the first spring 23 and descend. However, when the equipment moves, the handle 20 will be lifted, at which point the first magnetic block 21 and the second magnetic block 24 will separate, so the dual-axis motor 27 will not be activated, preventing damage or misoperation of the dual-axis motor 27 during movement. When the lifting component 22 descends, the contact piece 25 on its side will contact the contact piece 2603. The contact piece 25, the contact piece 2603 and the operator form a circuit. The circuit connection will send a signal to the operator indicating that the overall temperature is too high. Under the dual trigger, the operator will start the dual-axis motor 27.Emergency cooling is activated via a dual-trigger mechanism to improve the reliability of the device's heat dissipation. Therefore, the dual-axis motor 27 only activates under extreme high temperatures. The dual-trigger mechanism prevents accidental activation, as independent activation would lead to unnecessary energy consumption. The first output of the dual-axis motor 27 drives the rotating shaft, and the outer baffle 28 rotates with the shaft. Simultaneously, adjacent gears 29 at the ends of the shaft mesh with each other, causing multiple baffles 28 to open synchronously, opening the top of the cover and increasing the air exchange channel between the power supply box 1 and the outside environment, significantly improving heat exchange efficiency. A dustproof mesh is installed at the bottom of the cover to reduce dust entering the power supply box 1 and ensure the cleanliness of the device's interior. When the dual-axis motor 27 is in use, its second output drives the cam 32 to rotate. The cam 32 presses the piston 34 inside the conveyor cylinder 33, and the piston 34 compresses the outer second spring 35, thus conveying... Gas inside cylinder 33 is forced into the inner cavity of sleeve 37 on heat-conducting support plate 2 through delivery pipe 36, pushing push rod 38 inside sleeve 37 to move. Push rod 38 compresses the third spring 39 on the outside, causing the top baffle plate 40 to move, aligning the through groove 41 on the surface of baffle plate 40 with the second heat dissipation groove 30, allowing airflow to quickly flow out through the second heat dissipation groove 30, further expanding the heat dissipation channel and significantly improving heat dissipation efficiency. Dust cover 31 at the second heat dissipation groove 30 on the outside of power box 1 prevents external dust from entering the box, further enhancing the dustproof effect. When dual-axis motor 27 rotates, baffle plate 28 closes, and through groove 41 on the surface of baffle plate 40 is misaligned with the second heat dissipation groove 30, thus blocking the second heat dissipation groove 30. This allows the device to quickly return to its dustproof state after emergency heat dissipation, facilitating the protection of internal components of power box 1 and improving the adaptability and service life of the device.
