Description

Technical Field

[0001] This utility model relates to the field of automotive parts and heat dissipation technology, and in particular to a bridge housing back cover with high-efficiency heat dissipation function. Background Technology

[0002] In modern industrial equipment and electronic devices, heat dissipation has always been a key factor affecting equipment performance and lifespan. Especially in high-power equipment, such as motors, controllers, and other highly integrated electrical devices, heat accumulation can lead to increased equipment temperature, resulting in performance degradation, component aging, and even damage. To effectively address heat dissipation, heat dissipation structures are typically designed into the equipment casing or critical components to improve heat dissipation efficiency and maintain the equipment's normal operating temperature.

[0003] Currently, common heat dissipation structures mainly include traditional heat sinks, fan-assisted cooling, and liquid cooling systems. However, these technologies have certain limitations in practical applications. For example, while traditional heat sinks are simple in structure and low in cost, their heat dissipation efficiency is limited and cannot meet the heat dissipation requirements of high-power equipment; fan-assisted cooling can improve heat dissipation, but it generates noise during operation and its efficiency is easily reduced by dust accumulation after long-term use; liquid cooling systems, while having excellent heat dissipation performance, have a complex structure, are expensive, and pose a risk of leakage, making them unsuitable for widespread use in ordinary industrial equipment. In addition, the design of existing equipment casings often fails to fully consider the balance between heat dissipation and structural strength, potentially weakening overall mechanical performance while pursuing efficient heat dissipation.

[0004] To address the aforementioned issues, a novel heat dissipation design is urgently needed that combines efficient heat dissipation with structural strength and practicality. This is especially true for components like bridge housing back covers, which bear certain mechanical loads while simultaneously requiring heat dissipation. Achieving a dual improvement in heat dissipation and mechanical performance through optimized design has become a crucial research direction in the current technological field. Therefore, developing a bridge housing back cover with efficient heat dissipation capabilities not only solves the problem of insufficient heat dissipation in existing technologies but also provides a reliable guarantee for the stable operation of related equipment, possessing significant practical importance and application value. Utility Model Content

[0005] The purpose of this utility model is to provide a bridge housing back cover with efficient heat dissipation function, which solves the problems mentioned in the background art.

[0006] This invention is achieved by providing a bridge housing back cover with high-efficiency heat dissipation. The back cover mainly consists of a housing, heat-conducting fins on the outer surface of the housing, and cooling pipes embedded inside the housing. The housing is the main structure, and the heat-conducting fins and cooling pipes are mounted on it. The heat-conducting fins are movably connected to the housing via slots, which contain elastic pads to allow for flexible adjustment of their position and enhance contact stability. The cooling pipes are spirally distributed, with inlets and outlets at both ends. The inlets are connected to an external coolant supply device, allowing the coolant to circulate and remove heat from the housing. The inner wall of the housing has a heat-conducting coating that adheres tightly to the cooling pipes, improving heat transfer efficiency. The outer surface of the housing has grooves corresponding to the heat-conducting fins, allowing them to be embedded into the grooves to form an integrated structure, enhancing overall aesthetics and heat dissipation. The outer wall of the cooling pipes has a corrugated structure, increasing the contact area between the cooling pipes and the inner wall of the housing, further improving heat dissipation performance. The inlet and outlet are equipped with sealing rings made of high-temperature resistant rubber to ensure that there is no leakage during the coolant delivery process.

[0007] The bridge housing back cover of this utility model with high-efficiency heat dissipation function has a simple structure and low cost, and can be widely used in various mechanical equipment. Through the synergistic effect of heat-conducting fins and cooling pipes, the heat dissipation efficiency is significantly improved, effectively avoiding the performance degradation caused by heat accumulation and extending the service life of the equipment. At the same time, its flexible and adjustable design also provides greater adaptability and convenience for practical applications. Attached Figure Description

[0013] This utility model relates to a bridge housing back cover with high-efficiency heat dissipation function, the specific implementation of which is as follows (in conjunction with the attached drawing). Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1 As shown, the overall structure of this utility model includes a shell 1, heat-conducting fins 2, and cooling pipes 3. The shell 1 serves as the main structure, supporting and protecting the internal components. The heat-conducting fins 2 are movably connected to the shell 1 via slots 4. The cooling pipes 3 are spirally distributed inside the shell 1 and connected to the liquid inlet 6 and the liquid outlet 7. This design allows heat to be quickly dissipated through the synergistic effect of the heat-conducting fins 2 and the cooling pipes 3, thereby significantly improving heat dissipation efficiency.

[0014] Specifically, the housing 1 is the core component of the entire bridge housing back cover. Its material is preferably a metal with good thermal conductivity, such as aluminum alloy or copper alloy, to ensure that heat can be quickly transferred from the inside to the outside. The outer surface of the housing 1 is provided with grooves 9, such as... Figure 3 As shown, the groove 9 corresponds to the position of the heat-conducting fin 2, allowing the heat-conducting fin 2 to be embedded in the groove 9 to form an integrated structure. This design not only enhances the overall aesthetics but also increases the contact area between the heat-conducting fin 2 and the housing 1, further optimizing the heat dissipation effect. Furthermore, the inner wall of the housing 1 is coated with a thermally conductive coating 8, such as... Figure 2 As shown, the thermally conductive coating 8 is made of a high thermal conductivity material, such as graphene or carbon nanotube composite material. Its main function is to improve the efficiency of heat transfer from the inner wall of the shell 1 to the cooling pipe 3. The thermally conductive coating 8 is tightly attached to the cooling pipe 3 to ensure that heat can be efficiently conducted into the cooling pipe 3.

[0015] The design of the cooling pipe 3 is one of the key innovations of this utility model. It is spirally distributed inside the shell 1, with an inlet 6 and an outlet 7 at each end. This spiral layout allows the cooling pipe 3 to cover a larger area of ​​the inner wall of the shell 1, thereby maximizing the absorption of heat from inside the shell 1. The outer wall of the cooling pipe 3 has a corrugated structure 10, such as... Figure 2 As shown, the corrugated structure 10 increases the contact area between the cooling pipe 3 and the inner wall of the housing 1, further improving heat exchange efficiency. The cooling pipe 3 is preferably made of stainless steel or copper to ensure its durability and stability under high temperature and high pressure conditions. Both the inlet 6 and outlet 7 are equipped with sealing rings 11, such as... Figure 2 As shown, the sealing ring 11 is made of high-temperature resistant rubber, which can effectively prevent leakage during coolant circulation and ensure the long-term stable operation of the system.

[0016] The design of the heat-conducting fins 2 is also unique. They are movably connected to the housing 1 via slots 4, and elastic pads 5 are provided inside the slots 4, such as... Figure 3As shown. The elastic pad 5 is made of silicone or other elastic materials, and its main function is to enhance the contact stability between the heat-conducting fins 2 and the housing 1, while allowing the heat-conducting fins 2 to be flexibly adjusted in position according to actual needs. This adjustable design allows the present invention to adapt to the installation conditions and heat dissipation requirements of different equipment, thereby improving its practicality and adaptability. The heat-conducting fins 2 are preferably made of aluminum alloy or copper alloy, and their surface is specially treated to increase radiative heat dissipation capacity, for example, a black oxide film can be formed through anodizing process to further improve the heat dissipation effect.

[0017] In practical applications, the working principle of this invention is as follows: Coolant enters the cooling pipe 3 through the inlet 6 via an external coolant supply device. As the coolant flows within the cooling pipe 3, it absorbs heat from inside the housing 1 and is then discharged through the outlet 7. The coolant circulation process is driven by an external pump, ensuring that the coolant continuously removes heat. During this process, the heat inside the housing 1 is first transferred to the cooling pipe 3 through the thermally conductive coating 8 and then carried away by the coolant. Simultaneously, the thermally conductive fins 2, through close contact with the housing 1, dissipate heat from the outer surface of the housing 1 into the surrounding air, thus achieving a dual heat dissipation effect. The corrugated structure 10 of the cooling pipe 3 and the flexible adjustment design of the thermally conductive fins 2 work together to enable this invention to maintain stable heat dissipation performance under high-load operating conditions.

[0018] To further illustrate the specific application scenarios of this utility model, a detailed description is provided below using a practical example. Assume this utility model is applied to the bridge housing back cover of an industrial machine, which generates a large amount of heat during prolonged high-load operation. Traditional bridge housing back covers rely solely on natural heat dissipation or simple heat sink structures, which cannot meet the demand for rapid heat dissipation, leading to reduced equipment operating efficiency or even damage. This utility model, however, significantly improves heat dissipation efficiency through the synergistic effect of the heat-conducting fins 2 and the cooling pipes 3. In actual operation, technicians first install the housing 1 at the designated location on the machine, then adjust the position of the heat-conducting fins 2 according to the specific heat dissipation requirements of the equipment, aligning them with the heat source area. Subsequently, the inlet 6 and outlet 7 of the cooling pipes 3 are connected to an external coolant supply device, and the coolant circulation system is activated. During equipment operation, the heat inside the housing 1 is transferred to the cooling pipes 3 through the heat-conducting coating 8. The coolant absorbs heat as it flows within the cooling pipes 3 and is discharged through the outlet 7. Simultaneously, the heat-conducting fins 2 dissipate heat from the outer surface of the housing 1 into the surrounding air, thereby achieving a highly efficient dual heat dissipation effect. In this way, the present invention can effectively avoid the performance degradation caused by heat accumulation and extend the service life of the equipment.

[0019] Furthermore, the structural design of this utility model also boasts advantages such as low cost and ease of maintenance. The shell 1, heat-conducting fins 2, and cooling pipes 3 are all manufactured using common engineering materials, with mature production processes and controllable costs. Simultaneously, the design of the heat-conducting fins 2 being movably connected to the shell 1 via slots 4 allows for quick disassembly and installation when replacement or maintenance is required, reducing maintenance difficulty and cost. The inlet 6 and outlet 7 of the cooling pipes 3 both employ standardized interface designs, facilitating connection to external coolant supply devices and further enhancing its practicality.

[0020] In summary, the bridge housing back cover of this utility model, with its high-efficiency heat dissipation function, significantly improves heat dissipation efficiency through the synergistic effect of the heat-conducting fins 2 and the cooling pipes 3, effectively avoiding performance degradation caused by heat accumulation and extending the service life of the equipment. Its flexible and adjustable design and low-cost manufacturing process enable its widespread application in various types of mechanical equipment, making it of significant practical value.
