Navigation electronic cabinet with uniform air design

Abstract

The invention relates to a navigation electronic cabinet with uniform air design. The navigation electronic cabinet comprises a cabinet body, a plurality of plug-in box components, a plurality of guide components and a blower component. A plug-in box components are arranged in a column in the cabinet body. A plurality of air guide components are installed at the rear of a plurality of inserting components. The blower component is installed on the back plate of the cabinet body near the upper end part. Each inserting component is composed of a box body, a front panel, a rear panel, an upper cover plate and a lower cover plate. An upper air guide cavity and a low air guide cavity are respectively arranged on the upper part and the lower part of the box body which are positioned outside the inner cavity. Air guide fins are arranged in the upper air guide cavity and the lower air guide cavity. An upper air inlet and a lower air inlet are arranged at the front end of the box body, and an upper air outlet and a lower air outlet are arranged at the rear end of the box body. An upper air inlet opening and a lower air inlet opening are formed on the front panel, and an upper air outlet opening and a lower air outlet opening are formed on the rear panel so as to form an upper heat dissipation air channel and a lower heat dissipation air channel which are through in a front-and-back direction. Each group of air guide component is composed of upper and lower air guide plates so as to form an air guide channel. The cabinet has good uniform air effect,so that each plug-in box achieves better heat dissipation.

Description

technical field [0001] The invention belongs to the engineering application field of military electronic equipment, and relates to a floor-mounted electronic equipment cabinet structure widely applicable to the fields of navigation, spaceflight, aviation and land navigation, in particular to a navigation electronic cabinet with wind uniform design. Background technique [0002] The air duct design of electronic equipment cabinets in the traditional navigation field adopts the form of air intake from the bottom and air outlet from the top, or air outlet from the front and rear. A variety of subracks of different heights are installed in the navigation combination cabinet. Each subrack has power devices and modules, which need to be cooled by forced convection using the air duct system of the cabinet. The navigation electronic combination cabinet must meet the requirements of environmental adaptability, electromagnetic compatibility, maintainability, and scalability. [0003]...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the different positions of the sub-boxes in the traditional combination cabinet, the air path environment is also different, resulting in a mismatch between heat dissipation capacity and heating power

[0005] (2) Due to the position of the air inlet and fan layout in the traditional combined cabinet, it will cause a short circuit
