On-board electronic cabinet

Abstract

The invention provides an on-board electronic cabinet applied to the technical field of aviation electronic products. A front panel (1), a rear cover plate (2), an upper cover plate (3), a base plate (4), a left side plate (5) and a right side plate (6) of the on-board electronic cabinet form a hollow square frame structure. The inner surfaces of the front panel (1), the rear cover plate (2), the upper cover plate (3), the base plate (4), the left side plate (5) and the right side plate (6) are respectively provided with an oxidation layer (7) which is formed through conductive oxidation treatment. The outer surfaces of the front panel (1), the rear cover plate (2), the upper cover plate (3), the base plate (4), the left side plate (5) and the right side plate (6) are respectively coated with an enamel paint layer (8). According to the on-board electronic cabinet, the structure is simple, the electromagnetic compatibility is guaranteed, the resistance to electromagnetic interference is improved, the heat dissipation effect is improved, it is guaranteed that the on-board electronic cabinet can be operated under severe flight conditions, and work reliability and the adaptability of the on-board electronic cabinet and an airplane where the on-board electronic cabinet is carried are improved.

Description

technical field [0001] The invention belongs to the technical field of avionics products, and more specifically relates to an airborne electronic case. Background technique [0002] With the rapid development of avionics technology, the level of the airborne electronic chassis has become one of the important symbols to measure the performance of the aircraft. Looking back at the development process of airborne electronics, many special electronic chassis suitable for different models have been developed successively, such as: integrated avionics systems for fire control and flight control, multi-functional radar systems, atmospheric data processing systems, and weapon external storage management systems , integrated display system, data transmission system and other different types of tasks. The performance of the airborne electronic chassis hardware is determined by two parts: circuit characteristics and structural characteristics. The circuit characteristics determine the...

Problems solved by technology

In recent years, with the use of large-scale integrated circuits, the structural design of electronic equipment has developed towards the direction of ultra-small assembly, and the requirements for electronic system heat meters have become higher and higher, especially for electronic products used in special working environments. , such as electronic equipment that has been exposed to harsh marine climate conditions (temperature, high humidity, salt spray) for a long time, the metal materials in the equipment are easily damaged and corroded, and the non-metallic materials are also easily aged and invalidated, resulting in poor performance of components. Decrease, or even cause electrical short circuit, which seriously affects the performance and service life of the equipment. At the same time, due to the continuous improvement of electromagnetic compatibility design requirements, there is an urgent need for a versatile equipment that can work independently and be isolated from the outside world. The heat dissipation design has become a A crucial step for such devices to function properly
