Description

Technical Field

[0001] This utility model belongs to the field of power management and safety protection technology, specifically a power manager with heat resistance and explosion-proof function. Background Technology

[0002] With the continuous development of power management technology, various power managers have been widely used in home appliances, office equipment, industrial control, intelligent robots, and new energy fields. However, in practical applications, especially in high-temperature, high-load, or enclosed environments, power managers pose safety hazards such as thermal runaway, accelerated component aging, and even combustion or explosion due to severe heating of internal components. Although existing technologies have made some progress in power distribution, energy-saving control, and intelligent monitoring, they still have significant shortcomings in heat-resistant design and explosion-proof protection, making it difficult to meet the needs of high-safety application scenarios.

[0003] A search revealed a robot power management system with publication number CN112952942B, published on May 13, 2025. This system includes a control module, a pre-processing and protection module, a data acquisition module, a communication module, and a post-processing and protection module. It can filter, limit current, prevent reverse connection of the input power supply, and collect voltage, current, and temperature data in real time, providing overvoltage, undervoltage, overcurrent, and overtemperature protection based on the collected data. This solution monitors the system's temperature rise through temperature acquisition and can execute protective actions in case of abnormal temperatures, demonstrating some thermal management capabilities. However, this technology relies solely on electronic temperature detection and logic control, lacking heat-resistant design for the physical structure under high-temperature environments. For example, without high-temperature resistant encapsulation materials, active heat dissipation structures, or explosion-proof pressure relief mechanisms, heat accumulation in the event of internal short circuits or capacitor bulging could still lead to casing rupture or fire, failing to fundamentally achieve "explosion-proof" functionality. Furthermore, its temperature protection is reactive, lacking isolation and diffusion suppression measures for heat sources, making it difficult to cope with sudden thermal runaway scenarios.

[0004] A search revealed a power management system for an energy storage thermal management device controller, with publication number CN118041090B and publication date July 12, 2024. This system includes a liquid-cooled power management module, a charging protection module, and a thermal management control module. The liquid-cooled power management module utilizes integrated liquid cooling technology to actively dissipate heat from the power conversion module, supporting remote monitoring and output voltage regulation, and possessing strong thermal management capabilities. This innovative solution introduces a liquid-cooled integrated module, improving the heat dissipation efficiency of the power system and making it suitable for high-temperature operating scenarios such as high-power energy storage systems. However, this technology focuses on system-level thermal management, and its explosion-proof function is not a core design objective; it lacks explosion-proof valves, flame-retardant housings, or internal pressure relief structures. Furthermore, the liquid cooling system itself carries a risk of leakage; if the cooling medium seeps into the high-voltage circuit area, it may cause short circuits, sparks, or even explosions, increasing new safety hazards. In addition, the system has a complex structure and high cost, making it difficult to apply to the widespread use of small and medium-sized equipment.

[0005] The aforementioned issues indicate that existing power management technologies still have significant shortcomings in their safety design for high-temperature, high-power operation conditions. On the one hand, most solutions only focus on temperature monitoring and electrical protection, lacking comprehensive heat resistance and explosion-proof design from materials and structure to the system level. On the other hand, although some solutions introduce active cooling technology, they fail to consider both heat dissipation safety and explosion-proof reliability, failing to achieve integrated "heat resistance + explosion-proof" protection. Therefore, existing technologies are insufficient to meet the urgent need for inherent safety of power managers in confined spaces, high-temperature environments, or scenarios with high safety requirements (such as new energy vehicles, energy storage power stations, and industrial automation equipment).

[0006] To address these issues, this utility model provides a power manager with heat-resistant and explosion-proof functions, aiming to solve the problems of insufficient heat dissipation capacity, high risk of thermal runaway, and lack of effective explosion-proof measures in existing power managers under high-temperature conditions. By integrating high-temperature resistant materials, optimizing the internal heat flow channel design, adding an explosion-proof pressure relief structure and multiple temperature sensing mechanisms, it achieves an upgrade from passive protection to active protection, improving the operational safety and reliability of the equipment under extreme conditions. Summary of the Invention

[0007] This utility model relates to the field of power managers, specifically a power manager with heat resistance and explosion-proof functions. It includes a housing, an internal circuit module, a heat dissipation component, a protective component, and a temperature control sensing unit. The housing has a double-layer structure; the outer layer is made of high-strength flame-retardant material, and the inner layer is made of a ceramic matrix composite material with excellent thermal conductivity and high temperature resistance. A heat-insulating cavity is provided between the inner and outer layers, filled with a low thermal conductivity aerogel material. The internal circuit module is installed in the central area of ​​the housing and fixed to the base with bolts. An elastic support is provided between the base and the inner wall of the housing; the elastic support is made of high-temperature resistant silicone material to absorb vibration and impact.

[0008] Preferably, the heat dissipation assembly includes a heat-conducting plate, heat pipes, and a heat dissipation fin assembly. The heat-conducting plate is fixedly mounted on the top surface of the internal circuit module. Multiple heat pipes are welded to the edge of the heat-conducting plate, and the other ends of the heat pipes extend to the side wall of the outer casing and connect to the heat dissipation fin assembly. The heat dissipation fin assembly is embedded in a slot in the side wall of the outer casing and fixed with a sealing strip to prevent external dust or liquid from entering. The heat pipes are filled with a phase change material. When the temperature rises, the phase change material absorbs heat and undergoes a state transition, thereby rapidly transferring heat to the heat dissipation fin assembly. In addition, the surface of the heat dissipation fin assembly is coated with a high emissivity coating to enhance infrared radiation heat dissipation capability.

[0009] Preferably, the protective components include a pressure relief valve, an explosion-proof diaphragm, and a flame-retardant partition. The pressure relief valve is installed at the top center of the housing. A spring-loaded mechanism is installed inside the valve body; when the internal pressure exceeds a set threshold, the spring-loaded mechanism pushes the valve core open, releasing the internal pressure. The explosion-proof diaphragm is located below the pressure relief valve and is made of multi-layer composite material, including a high-temperature resistant polyimide film and a metal foil layer. The explosion-proof diaphragm is fixed to the inner wall of the housing via a snap-fit ​​structure. The flame-retardant partition is located around the internal circuit modules. The flame-retardant partition is made of ceramic fiberboard and is connected to the inner wall of the housing by screws. It isolates the internal components from the external environment and prevents the spread of flames.

[0010] Preferably, the temperature control sensing unit includes multiple temperature sensors and a signal processing module. The temperature sensors are respectively arranged at key heat-generating components of the internal circuit module and on the inner wall of the outer casing. The temperature sensors are connected to the signal processing module via wires. The signal processing module is installed in the bottom area of ​​the outer casing and fixed to the base with bolts. The signal processing module receives data collected by the temperature sensors and analyzes and judges the temperature change trend using algorithms. When an abnormal temperature is detected, the signal processing module sends a command to the heat dissipation component to initiate the heat absorption process of the phase change material, and simultaneously triggers the pressure relief valve in the protection component.

[0011] This invention effectively reduces the impact of the external environment on the internal circuit modules through a double-layer shell design combined with an aerogel-material insulated cavity, while avoiding safety hazards caused by heat accumulation at high temperatures. The combined design of the heat-conducting plate, heat-conducting pipe, and heat dissipation fins achieves efficient heat conduction and dissipation, especially under high-temperature conditions, where the phase change material's state transition significantly improves heat dissipation efficiency. Furthermore, the synergistic effect of multiple protection mechanisms—a pressure relief valve, an explosion-proof membrane, and a flame-retardant partition—can promptly release pressure and block the flame propagation path in the event of a sudden increase in internal pressure or localized overheating, thereby reducing the risk of explosion.

[0012] Through the above technical solution, this utility model solves the problems of insufficient heat dissipation capacity, high risk of thermal runaway, and lack of effective explosion-proof measures in existing power managers in high-temperature environments. It provides a comprehensive solution from material selection to structural design to ensure the safety and reliability of equipment operation under extreme conditions. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] This utility model provides a power manager with heat-resistant and explosion-proof functions, the specific implementation of which is described in conjunction with the appendix. Figure 1 To be continued Figure 4 A detailed description is provided. The power manager includes a housing 1, an internal circuit module 2, a heat dissipation component 3, a protective component 7, and a temperature control sensing unit 11. The components achieve the overall function through specific structural design and connection relationships.

[0022] As attached Figure 1 As shown, the outer shell 1 has a double-layer structure. The outer layer is made of high-strength flame-retardant material, and the inner layer is made of ceramic matrix composite material with excellent thermal conductivity and high temperature resistance. A heat-insulating cavity 14 is provided between the inner and outer layers, and the heat-insulating cavity 14 is filled with aerogel material 15 with low thermal conductivity. The design of the heat-insulating cavity 14 significantly reduces the impact of external environmental temperature changes on the interior of the outer shell 1, while the low thermal conductivity of the aerogel material 15 further improves the heat insulation effect. The internal circuit module 2 is installed in the central area of ​​the outer shell 1 and fixed to the base 16 by bolts. An elastic support 17 is provided between the base 16 and the inner wall of the outer shell 1. The elastic support 17 is made of high-temperature resistant silicone material to absorb vibration and impact. The thickness of the elastic support 17 is designed according to actual needs to ensure effective buffering and protection of the internal circuit module 2 when subjected to external impact.

[0023] The heat dissipation assembly 3 includes a heat-conducting plate 4, heat-conducting pipes 5, and a heat dissipation fin assembly 6. The heat-conducting plate 4 is fixedly installed on the top surface of the internal circuit module 2. Multiple heat-conducting pipes 5 are connected to the edge of the heat-conducting plate 4 by welding. The other end of the heat-conducting pipes 5 extends to the side wall of the outer casing 1 and is connected to the heat dissipation fin assembly 6. The heat-conducting pipes 5 are filled with phase change material. When the temperature rises, the phase change material absorbs heat and undergoes a state change, thereby quickly transferring heat to the heat dissipation fin assembly 6. The heat dissipation fin assembly 6 is embedded in the slots of the side wall of the outer casing 1 and fixed by sealing strips to prevent external dust or liquid from entering. The surface of the heat dissipation fin assembly 6 is coated with a high emissivity coating (18). The coating material is a ceramic-based coating with high infrared emissivity, which can enhance the infrared radiation heat dissipation capability in high-temperature environments. The contact surface between the heat-conducting plate 4 and the internal circuit module 2 is filled with thermally conductive silicone grease to reduce thermal resistance and improve heat conduction efficiency.

[0024] The protective assembly 7 includes a pressure relief valve 8, an explosion-proof membrane 9, and a flame-retardant partition 10. The pressure relief valve 8 is installed at the top center of the housing 1. A spring-loaded mechanism is installed inside the valve body of the pressure relief valve 8. When the internal pressure exceeds a set threshold, the spring-loaded mechanism pushes the valve core to open, releasing the internal pressure. The explosion-proof membrane 9 is located below the pressure relief valve 8. The explosion-proof membrane 9 is made of multi-layer composite material, including a high-temperature resistant polyimide film and a metal foil layer. The explosion-proof membrane 9 is fixed to the inner wall of the housing 1 by a snap-fit ​​structure. The flame-retardant partition 10 is located around the internal circuit module 2. The flame-retardant partition 10 is made of ceramic fiber board and is connected to the inner wall of the housing 1 by screws. The design of the flame-retardant partition 10 can isolate internal components from the external environment while preventing the spread of flames. The opening pressure of the pressure relief valve 8 is adjusted by the preload of the spring-loaded mechanism to adapt to the needs of different application scenarios.

[0025] The temperature control sensing unit 11 includes multiple temperature sensors 12 and a signal processing module 13. The temperature sensors 12 are respectively arranged on key heat-generating parts of the internal circuit module 2 and on the inner wall of the outer casing 1. The temperature sensors 12 are connected to the signal processing module 13 via wires. The signal processing module 13 is installed in the bottom area of ​​the outer casing 1 and fixed to the base 16 with bolts. The signal processing module 13 receives the data collected by the temperature sensors 12 and analyzes and judges the temperature change trend through algorithms. When an abnormal temperature is detected, the signal processing module 13 sends a command to the heat dissipation component 3 to start the heat absorption process of the phase change material, and at the same time triggers the pressure relief valve 8 in the protection component 7 to operate. The number and distribution of the temperature sensors 12 are optimized according to the structural characteristics of the internal circuit module 2 to ensure comprehensive monitoring of temperature changes in key parts.

[0026] During actual operation, when the power manager is in a high-temperature environment, the heat generated by the internal circuit module 2 is transferred to the heat pipe 5 through the heat-conducting plate 4. The phase change material inside the heat pipe 5 absorbs the heat and undergoes a state change, rapidly transferring the heat to the heat dissipation fin assembly 6. The heat dissipation fin assembly 6 dissipates the heat to the external environment through infrared radiation and convection, thereby achieving efficient heat dissipation. At the same time, the aerogel material 15 inside the heat insulation cavity 14 effectively isolates the external high-temperature environment, preventing heat from being transferred back to the internal circuit module 2.

[0027] When the internal pressure increases due to temperature rise, the pressure relief valve 8 opens via the action of the spring-loaded mechanism to release the internal pressure and prevent excessive pressure from damaging the equipment. If the pressure relief valve 8 cannot completely release the pressure, the explosion-proof diaphragm 9 will rupture to further release the pressure and ensure the safety of the equipment. The flame-retardant partition 10 acts as an isolation barrier in the event of localized overheating or flame spread, preventing the flame from propagating to other areas.

[0028] The temperature control sensing unit 11 monitors the temperature changes of the internal circuit module 2 and the inner wall of the outer casing 1 in real time. When an abnormal temperature is detected, the signal processing module 13 analyzes and judges the temperature change trend through algorithms and sends a command to the heat dissipation component 3 to start the heat absorption process of the phase change material. At the same time, the signal processing module 13 triggers the pressure relief valve 8 in the protection component 7 to ensure the safety and reliability of the equipment under extreme conditions.

[0029] Through the above specific embodiments, this utility model achieves a comprehensive solution from material selection to structural design, ensuring the safety and reliability of the equipment under extreme conditions. The double-layer structure of the outer shell 1, combined with the heat-insulating cavity 14 of aerogel material 15, effectively reduces the impact of the external environment on the internal circuit module 2, while avoiding safety hazards caused by heat accumulation in high-temperature environments. The combined design of the heat-conducting plate 4, heat-conducting pipe 5, and heat dissipation fin group 6 achieves efficient heat conduction and dissipation, especially under high-temperature conditions, the phase change material's state transition significantly improves heat dissipation efficiency. The multiple protection mechanisms of the pressure relief valve 8, explosion-proof membrane 9, and flame-retardant partition 10 work synergistically to release pressure and block the flame propagation path in time when the internal pressure suddenly increases or local overheating occurs, thereby reducing the risk of explosion.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0031] In high-temperature industrial environments, power managers are installed in enclosed electrical cabinets to control and protect the operation of critical equipment. Due to the limited space and ventilation within these cabinets, ambient temperatures can reach over 80°C, placing extremely high demands on the heat resistance and explosion-proof performance of the power manager. In this situation, the power manager achieves its function through the following steps:

[0032] First, when the internal circuit module 2 starts working, the heat it generates is transferred to the heat pipe 5 through the heat-conducting plate 4. The phase change material filled inside the heat pipe 5 undergoes a state change after absorbing heat, for example, from solid to liquid, thereby rapidly conducting the heat to the heat dissipation fin assembly 6. The heat dissipation fin assembly 6 is embedded in the slots in the side wall of the outer casing 1 and dissipates heat to the external environment through infrared radiation and convection. The high emissivity coating (18) on the surface of the heat dissipation fin assembly 6 further enhances the infrared radiation heat dissipation capability, ensuring that high heat exchange efficiency is maintained even under high-temperature conditions. At the same time, the contact surface between the heat-conducting plate 4 and the internal circuit module 2 is filled with thermally conductive silicone grease, which effectively reduces thermal resistance and improves heat conduction efficiency.

[0033] Secondly, the double-layer structure of the outer shell 1 provides significant thermal insulation against the high-temperature external environment. The outer high-strength flame-retardant material can withstand high temperatures and mechanical impacts, while the inner ceramic matrix composite material possesses excellent thermal conductivity and high-temperature resistance. The thermal insulation cavity 14 between the inner and outer layers is filled with a low thermal conductivity aerogel material 15, which effectively isolates external heat from the interior, preventing heat accumulation that could lead to overheating or aging of components. Furthermore, the elastic support 17 is made of high-temperature resistant silicone, which not only absorbs vibrations and impacts but also maintains stable physical properties under extreme conditions, thereby protecting the internal circuit module 2 from external interference.

[0034] When the internal pressure increases due to temperature rise, the pressure relief valve 8 opens via the action of a spring-loaded mechanism. The valve core of the pressure relief valve 8 is pushed open by the spring-loaded mechanism when the internal pressure exceeds a set threshold, thereby releasing the internal pressure and preventing damage to the equipment due to excessive pressure. If the pressure relief valve 8 cannot completely release the pressure, the explosion-proof diaphragm 9 will rupture to further release the pressure. The explosion-proof diaphragm 9 is made of multi-layer composite material, including a high-temperature resistant polyimide film and a metal foil layer. This structure ensures both the strength of the diaphragm and its ability to rupture rapidly under sudden pressure increases, ensuring the safety of the equipment.

[0035] Meanwhile, the flame-retardant partition 10 acts as an isolation barrier in case of localized overheating or flame spread. Made of ceramic fiberboard, the flame-retardant partition 10 possesses excellent high-temperature resistance and flame-retardant properties, effectively preventing the spread of flames to other areas and thus preventing fire spread. The flame-retardant partition 10 is connected to the inner wall of the outer casing 1 by screws, ensuring its stable position and function even under high-temperature conditions.

[0036] Throughout operation, the temperature sensing unit 11 monitors the temperature changes of the internal circuit module 2 and the inner wall of the outer casing 1 in real time. Multiple temperature sensors 12 are respectively positioned at key heat-generating areas of the internal circuit module 2 and on the inner wall of the outer casing 1, transmitting the collected data to the signal processing module 13 via wires. The signal processing module 13 analyzes the received data to determine the temperature change trend. When an abnormal temperature is detected, the signal processing module 13 sends a command to the heat dissipation assembly 3 to initiate the heat absorption process of the phase change material within the heat pipe 5, simultaneously triggering the pressure relief valve 8 in the protection assembly 7. The number and distribution of the temperature sensors 12 are optimized based on the structural characteristics of the internal circuit module 2 to ensure comprehensive monitoring of temperature changes in key areas.

[0037] Through the above steps, this utility model achieves a comprehensive solution from material selection to structural design, ensuring the safety and reliability of the equipment under extreme conditions. The double-layer structure of the outer shell 1, combined with the heat-insulating cavity 14 of aerogel material 15, effectively reduces the impact of the external environment on the internal circuit module 2, while avoiding safety hazards caused by heat accumulation in high-temperature environments. The combined design of the heat-conducting plate 4, heat-conducting pipe 5, and heat dissipation fin group 6 achieves efficient heat conduction and dissipation, especially under high-temperature conditions, the phase change material's state transition significantly improves heat dissipation efficiency. The multiple protection mechanisms of the pressure relief valve 8, explosion-proof membrane 9, and flame-retardant partition 10 work synergistically to release pressure and block the flame propagation path in a timely manner when internal pressure suddenly increases or local overheating occurs, thereby reducing the risk of explosion.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
