Waterproof and dustproof electromagnetic shielding cabinet structure

Abstract

This invention relates to a waterproof and dustproof electromagnetic wave shielding cabinet structure, comprising a cabinet body, door panels, electromagnetic wave shielding components, a rack assembly, heat dissipation elements, drainage elements, and power supply elements. The door panels and the cabinet body form a closed space. The electromagnetic wave shielding components include a waveguide mesh and waveguide strips. The waveguide strips are arranged around the perimeter of the joint between the door panel and the cabinet body, and when the door panel is closed, they contact and conduct with the waveguide mesh to form a continuous shielding path. The heat dissipation elements are located on the outside of the cabinet body and communicate with the closed space to dissipate internal heat. The drainage elements collect and drain condensate generated by the heat dissipation elements. Thus, the cabinet combines waterproofing, dustproofing, heat dissipation, and electromagnetic wave shielding functions.
