Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to a heat dissipation protection device for fire protection equipment, belonging to the field of electronic equipment heat dissipation and safety protection technology, and is applicable to electronic equipment such as fire control equipment and fire monitoring devices that operate in high temperature or complex environments. Background Technology

[0002] With the continuous improvement of fire protection automation and informatization, fire control equipment, fire monitoring devices, and related electronic systems are widely used in the fire protection field. These fire protection devices typically operate under high temperature, high load, or long-term continuous operation conditions. Their internal electronic components generate a large amount of heat during operation. If this heat cannot be dissipated in time, it can easily lead to performance degradation, unstable operation, or even malfunction, affecting the reliability and safety of the fire protection system.

[0003] Existing fire-fighting equipment commonly uses cooling fans and heat sinks to dissipate heat from electronic components. However, these methods often rely on a single heat dissipation structure with a relatively simple heat dissipation path. In high-temperature environments or when the internal space of the equipment is limited, the heat dissipation effect can be easily restricted. Furthermore, the enclosure structure of some fire-fighting equipment does not adequately consider flame retardancy and heat insulation. When the external ambient temperature is high or there is a risk of open flame, it is difficult to simultaneously meet the heat dissipation requirements and fire safety requirements.

[0004] Therefore, how to provide a heat dissipation device with a reasonable structure that can take into account both heat dissipation performance and flame retardancy and heat insulation protection requirements in fire protection equipment has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an innovative and efficient heat dissipation system. Most existing heat dissipation solutions rely on a single method, such as heat sinks or fans. These designs have limited heat dissipation effectiveness in high-temperature environments, leading to overheating and affecting equipment stability and lifespan. Furthermore, existing technologies often fail to effectively address the multiple requirements of fire resistance, heat insulation, and efficient heat dissipation. Therefore, this invention, through a three-layer composite structure design, provides a comprehensive solution with efficient heat dissipation, intelligent adjustment, and fire resistance and heat insulation functions, aiming to solve problems such as insufficient heat dissipation, heat accumulation, and fire risk in existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The fire-retardant layer is made of ceramic fiber composite material, which possesses extremely high temperature resistance and flame-retardant properties. In fire or high-temperature environments, this layer can quickly isolate the ignition source, preventing the flame from spreading into the equipment and ensuring its safety. The material's advantage lies in its high-temperature resistance exceeding 1200°C, allowing it to operate continuously at high temperatures without failure, effectively protecting internal electronic components. The excellent flame-retardant effect of ceramic fiber material effectively isolates the ignition source, preventing damage to the equipment caused by external fires. Furthermore, the ceramic fiber composite material also boasts a low coefficient of thermal expansion and high mechanical strength, ensuring that this layer maintains its structural integrity even in high-temperature environments, preventing failure due to thermal expansion and contraction or physical changes at high temperatures.

[0007] Furthermore, the insulation layer utilizes aerogel composite materials, which possess extremely low thermal conductivity, effectively preventing external heat transfer to the equipment and reducing the impact of the external environment. The thermal insulation performance of aerogel composite materials surpasses that of traditional insulation materials, with a thermal conductivity below 0.03 W / (m·K), enabling the equipment to maintain stable internal temperature even in extreme high-temperature environments and preventing overheating due to external heat. Compared to other insulation materials, aerogel composite materials not only have a lower thermal conductivity but also offer lighter weight and better durability, making them suitable for long-term high-temperature applications.

[0008] Furthermore, the heat-conducting layer utilizes a copper alloy composite material, which possesses excellent thermal conductivity, enabling rapid transfer of heat generated within the equipment to the heat dissipation fins. Copper alloy has a high thermal conductivity, not less than 400 W / (m·K), ensuring rapid heat conduction and uniform distribution, effectively preventing localized overheating. The use of copper alloy composite material not only improves heat dissipation efficiency but also reduces the heat dissipation lag and heat accumulation problems inherent in traditional heat dissipation materials. Through this design, the heat-conducting layer can achieve rapid heat conduction in high-temperature environments, quickly dissipating heat from internal components and preventing equipment malfunctions due to insufficient heat dissipation.

[0009] The heat dissipation fin system is tightly connected to the heat-conducting layer, ensuring that heat is rapidly conducted to the fin surface and quickly dissipated by the fan. The fan speed is automatically adjusted according to the real-time temperature changes of the equipment, thus ensuring optimal heat dissipation under different operating conditions. The temperature control system precisely adjusts the fan speed through an intelligent temperature control module, optimizing heat dissipation while reducing fan energy consumption and noise. This design not only adapts to the needs of different working environments but also automatically adjusts the operating strategy under high-temperature conditions, maintaining system stability and reducing power consumption.

[0010] This system employs a three-layer structure design to efficiently dissipate heat generated inside the equipment and effectively isolate it from external high temperatures. The fire-retardant layer effectively isolates the fire source, preventing the spread of fire and ensuring equipment safety; the insulation layer effectively blocks the transfer of external heat sources, reducing the impact of external heat on the equipment; and the heat-conducting layer, through a highly efficient heat conduction system, ensures that heat can be rapidly conducted from the inside to the outside, guaranteeing stable equipment operation.

[0011] Furthermore, the system's innovation lies not only in the selection of materials and the design of its layered structure, but also in its comprehensive solution that integrates heat dissipation, insulation, and fire resistance. Compared to existing technologies, the three-layer composite structure design enables the heat dissipation system to achieve more efficient heat management while possessing stronger fire-retardant properties, ensuring stable operation of the equipment in extreme high-temperature or fire environments. In addition, the system's automatic temperature control design optimizes heat dissipation efficiency and automatically adjusts fan speed according to temperature, reducing energy consumption and extending the equipment's lifespan.

[0012] This system is not only suitable for fire-fighting equipment, but also for any equipment requiring efficient heat dissipation in extreme temperature environments while ensuring fire resistance and thermal insulation. It is widely used in electronic equipment, battery management systems, control systems, drones, power equipment, and automobiles. Furthermore, this innovative design not only solves problems such as insufficient heat dissipation, heat accumulation, and fire risks in existing technologies, but also promotes technological advancements in related industries through efficient heat dissipation, energy saving and emission reduction, and improved equipment reliability, demonstrating broad market application prospects.

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, but these embodiments do not constitute a limitation on the scope of protection of the present invention.

[0020] like Figure 1 As shown, this embodiment provides a heat dissipation device, including a heat dissipation body mounted on a support base 7. The heat dissipation body includes a shell 1, the interior of which forms a mounting cavity for accommodating heat dissipation components. The side walls and top of the shell 1 are provided with ventilation structures for air circulation.

[0021] Multiple cooling fan assemblies 3 are provided on one side of the outer casing 1. These cooling fan assemblies 3 are used to introduce external cold air into the outer casing 1 or to exhaust hot air from inside the outer casing 1, thereby forming a forced convection cooling path. For example... Figure 2 As shown, the cooling fan assembly 3 includes fan blades 4, which rotate as the cooling fan assembly 3 operates to achieve airflow.

[0022] like Figure 1 and Figure 3 As shown, a heat dissipation fin assembly 5 is provided on the top of the outer casing 1. The heat dissipation fin assembly 5 is located above the outer casing 1 and is used to increase the heat dissipation area and accelerate the conduction and diffusion of heat to the outside air. The heat dissipation fin assembly 5 and the outer casing 1 can be an integrally formed structure, or they can be fixedly connected by welding, screwing, or pressing.

[0023] like Figure 3 As shown, the heat dissipation module 6 is disposed below the heat dissipation fin assembly 5. The heat dissipation module 6 includes multiple sets of parallel heat dissipation units, each of which is in close contact with the component being dissipated to conduct the heat generated by the component to the heat dissipation fin assembly 5. The bottom of the heat dissipation module 6 is fixedly mounted on the supporting base 7 to ensure the stability of the overall structure.

[0024] like Figure 4 As shown, the heat dissipation module 6 is symmetrically arranged above the supporting base 7. The supporting base 7 is used to support and fix the entire heat dissipation device, so that the heat dissipation device can be stably installed inside the equipment or on the surface of the equipment. The supporting base 7 can be the equipment chassis, the equipment shell, or an independently set mounting platform.

[0025] In this embodiment, the airflow generated by the cooling fan assembly 3, together with the heat dissipation fin assembly 5 and the heat dissipation module 6, enables heat to be transferred and released along the path of the component being cooled → heat dissipation module 6 → heat dissipation fin assembly 5 → air convection, thereby achieving heat dissipation of the component being cooled.

[0026] like Figure 5As shown, the enclosure wall is a multi-layered composite structure for protecting electronic components, comprising a flame-retardant layer 8, a heat insulation layer 9, and a heat spreader 10 arranged sequentially. The flame-retardant layer 8 is located on the outer side of the enclosure wall to provide flame-retardant protection for the electronic components inside the enclosure in the event of abnormally high temperatures or open flames. The heat insulation layer 9 is located between the flame-retardant layer 8 and the heat spreader 10 to reduce the transfer of external heat to the interior of the enclosure. The heat spreader 10 is located on the inner side of the enclosure wall to evenly distribute the heat generated by the electronic components inside the enclosure, thus preventing localized heat concentration.

[0027] In a preferred embodiment, the heat spreader 10 is a component made of a high thermal conductivity material, preferably not less than 200 W / (m·K), more preferably not less than 400 W / (m·K); for example, it can be made of oxygen-free copper, copper alloy, aluminum alloy or graphite-based composite material.

[0028] In a preferred embodiment, the insulation layer 9 is a low thermal conductivity material layer, with a thermal conductivity preferably not higher than 0.05 W / (m·K), more preferably not higher than 0.03 W / (m·K); for example, it can be made of aerogel, ceramic fiber or microporous insulation material.

[0029] In a preferred embodiment, the flame-retardant layer 8 is a flame-retardant protective layer, and its material preferably meets the requirements of UL94 V-0 flame retardant rating or equivalent flame retardant rating, and can be a flame-retardant polymer material, an inorganic flame-retardant material or a flame-retardant coating structure.

[0030] The above are merely preferred embodiments of the present invention. Those skilled in the art can make several modifications or substitutions without departing from the concept of the present invention, and all such modifications or substitutions should fall within the protection scope of the present invention.
