Description

Technical Field

[0001] This utility model relates to the field of airborne VPX equipment technology, specifically to an airborne VPX system platform. Background Technology

[0002] In the field of avionics, the VPX system, as an advanced open architecture standard, has been widely used in airborne electronic systems due to its advantages such as high bandwidth, high performance, high reliability, and good scalability. The VPX system typically uses the VPX motherboard as its core processing component, undertaking critical functions of data processing and transmission. However, in the complex airborne environment, the VPX motherboard faces numerous challenges. Firstly, the airborne environment exhibits a wide temperature range, from the low temperatures of high altitudes to the high temperatures near the engine, resulting in significant temperature differences. Simultaneously, the equipment itself generates a large amount of heat during operation. If heat cannot be dissipated effectively and promptly, high temperatures can lead to performance degradation, shortened lifespan, and even malfunctions of electronic components, severely impacting the system's stability and reliability. Secondly, the airborne environment contains a large amount of dust, water vapor, salt spray, and other impurities. Once these impurities enter the casing, they easily adhere to the surfaces of electronic components, causing short circuits, corrosion, and other problems, further threatening the normal operation of the system.

[0003] Traditional airborne electronic equipment (Airborne Electronic Devices) primarily relies on natural cooling or simple forced air cooling for heat dissipation. While simple forced air cooling improves heat dissipation efficiency to some extent, it typically lacks effective dustproof, waterproof, and salt spray protection measures. For example, common cooling fans directly draw outside air into the casing, which, while removing heat, also introduces large amounts of dust, moisture, and other impurities, accelerating the aging and damage of electronic components. Moreover, when the equipment is not running, the vents cannot be effectively sealed, allowing external impurities to still enter the casing and pose potential hazards. Therefore, to meet the stable operation requirements of airborne VPX system platforms in complex environments and improve their heat dissipation efficiency and protection capabilities, this technical solution aims to provide an airborne VPX system platform with both excellent heat dissipation and protection performance, achieving a combination of heat dissipation and protection functions.

[0025] To provide a clearer explanation and illustration of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are described below. The following description is merely exemplary and not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically illustrate the concept and principle of the embodiments of this disclosure and do not necessarily show the specific dimensions and proportions of the various embodiments of this disclosure. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0026] The airborne VPX system platform includes a VPX housing 1, which is generally rectangular in shape. Its internal cavity provides space for installing internal components. The VPX motherboard 4, as the core processing component of the system, is installed within the cavity, undertaking crucial data processing and transmission functions. A front panel 2 is fixed to the front surface of the VPX housing 1. The front panel 2 is constructed from a metal plate 2-1, which provides sufficient strength to protect the internal components. Air intake grilles 2-2 are arranged on the left and right sides inside the metal plate 2-1, forming a strip-like pattern to allow air to enter the housing. A strip frame 2-3 is fixed to the front end face of the air intake grilles 2-2, covering their openings. The inner walls of the frame have slots for inserting plate-type filter cotton 2-4 vertically into these slots for stable installation. The function of the plate filter cotton 2-4 is to filter particles and moisture in the air, preventing these impurities from entering the casing and damaging components such as the VPX motherboard 4, thereby ensuring the stable operation of the system in complex airborne environments.

[0027] A back panel 3 is fixed to the rear surface of the VPX casing 1. The back panel 3 includes a fixing plate 3-1, which forms the basic structure of the back panel 3 and serves to support and fix other components. A cooling fan 5 is fixed inside the fixing plate 3-1. The cooling fan 5 starts when the system is running, exhausting hot air from inside the casing to the outside, achieving a cooling effect. Multiple honeycomb-shaped air outlets 3-2 are provided inside the fixing plate 3-1. The design of the honeycomb-shaped air outlets 3-2 increases the air outlet area and improves the heat dissipation efficiency. A closable air outlet frame is provided on the rear end face of the back panel 3. The closable air outlet frame includes a rectangular frame 3-3, which covers the rear end face of the honeycomb-shaped air outlets 3-2, protecting and guiding the airflow. Multiple openings 3-4 are provided on the outer surface of the rectangular frame 3-3, providing channels for hot air to be exhausted. A flap 3-5 is rotatably mounted inside the opening 3-4. A fixing block 3-6 is fixed to the inner surface of each flap 3-5. A rotating shaft 3-8 is rotatably connected to the side wall of each fixing block 3-6. The end of the rotating shaft 3-8 away from the fixing block 3-6 is fixedly connected to the inner side wall of the rectangular frame 3-3. This structure allows the flap 3-5 to rotate around the rotating shaft 3-8. A torsion spring 3-7 is fixed to the outer ring of the rotating shaft 3-8. One end of the torsion spring 3-7 is fixed to the outer ring of the rotating shaft 3-8, and the other end is fixed to the inner surface of the flap 3-5. When the cooling fan 5 is not running, the torsion spring 3-7 is in its natural state. Under the action of the torsion spring 3-7, the flap 3-5 fits tightly against the opening 3-4, sealing the opening and preventing external dust, moisture, and other impurities from entering the casing through the opening 3-4. When the cooling fan 5 starts and exhausts hot air, the hot air exerts an outward thrust on the flap 3-5, causing the flap 3-5 to rotate around the pivot 3-8, thereby opening the opening 3-4 and allowing the hot air to escape smoothly. When the cooling fan 5 stops working, the torsion spring 3-7 uses its elasticity to pull the flap 3-5 back, re-couples it with the opening 3-4, and closes the opening 3-4 again.

[0028] In addition, a layer of rubber sealing gaskets is fixed to the outer surface of each flap 3-5 with adhesive. These gaskets fill the gap between flap 3-5 and opening 3-4, further enhancing the sealing effect and effectively preventing external impurities from entering the housing. This ensures the stable and reliable operation of the airborne VPX system platform in complex and changing airborne environments, meeting the requirements of airborne equipment for dustproof, waterproof, and salt spray protection. Through the coordinated work of the aforementioned components, the entire airborne VPX system platform effectively protects and dissipates heat from the VPX motherboard 4.

[0029] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: When the airborne VPX system platform is working, the VPX motherboard 4 processes data and transmits information within the VPX housing 1, generating heat during this process. The cooling fan 5 starts, creating a negative pressure environment inside the housing. External air enters through the air intake grille 2-2 on the front panel 2. During this process, the plate-type filter cotton 2-4, fixed in the slot within the strip frame 2-3, filters the air, removing salt spray, particles, and moisture to prevent impurities from entering the housing and damaging components such as the VPX motherboard 4. The filtered air enters the housing cavity and exchanges heat with the heat-generating components such as the VPX motherboard 4, absorbing heat and becoming hot air. Hot air flows towards the back panel 3 under the action of the cooling fan 5, reaching the honeycomb-shaped air outlet 3-2 of the back panel 3. At this time, the hot air exerts an outward pushing force on the flap 3-5 inside the opening 3-4 of the rectangular frame 3-3 in the closable air outlet frame. The flap 3-5 rotates around the rotating shaft 3-8, which is fixed on the fixing block 3-6 and connected to the inner side wall of the rectangular frame 3-3. At the same time, the torsion spring 3-7 on the outer ring of the rotating shaft 3-8 is twisted, the opening 3-4 is opened, and the hot air is discharged to the outside of the casing through the opening 3-4, thus achieving heat dissipation. When the cooling fan 5 stops working, there is no longer any pressure to exhaust air from inside the casing. The torsion spring 3-7, which has been twisted, returns to its original shape using its own elasticity, pulling back the flap 3-5 so that the flap 3-5 and the opening 3-4 are tightly fitted again. At the same time, the rubber sealing gasket fixed by adhesive on the outer surface of the flap 3-5 fills the gap between the flap 3-5 and the opening 3-4, sealing the opening 3-4 and preventing external dust, moisture and other impurities from entering the casing through the opening 3-4, thus ensuring the stable operation of the airborne VPX system platform in complex airborne environments.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
