AI Technical Summary

Technical Problem

The cylindrical inlet holes on the wave absorbing plate of the same thickness lead to a short trajectory of electromagnetic wave reflection, which easily makes the wave absorbing plate saturated and reduces the wave absorbing effect.

Method used

The wave inlet hole of the wave absorbing motherboard is designed as a "wavy shape", and multiple bumps are fixedly connected on the inside to form an irregular and rough surface structure. At the same time, the wave absorbing secondary plate and the heat dissipation plate are fixedly connected on the side of the wave absorbing motherboard, and a heat conduction hole and a heat conduction rod are provided on the side of the heat dissipation plate to improve the heat dissipation effect.

Benefits of technology

Through the design of "wave-shaped" wave inlet holes and bumps, the reflection path of electromagnetic waves is extended, energy loss is increased, the absorption effect is improved, and the upper saturation limit of the absorber motherboard is increased through the heat dissipation structure, solving the problem that the absorber plate is easily in a saturated state.

Abstract

The utility model relates to the technical field of plates, in particular to a reinforced electromagnetic wave-absorbing plate which comprises a wave-absorbing main plate, a plurality of wave inlet holes are formed in one side of the wave-absorbing main plate in a penetrating mode, the wave inlet holes are all arranged to be in a wave shape and are distributed in a linear array mode, a plurality of protruding blocks are fixedly connected to the inner sides of the wave inlet holes, and the protruding blocks are arranged in the wave inlet holes. The plurality of bumps are irregularly arranged and have rough surfaces; the wave-absorbing main board has the advantages that the cylindrical wave inlet holes are arranged to be in a wave shape, under the condition that the thickness of the wave-absorbing main board is the same, electromagnetic waves can have a longer reflection path, and therefore heat energy lost by electromagnetic wave reflection is larger, the wave-absorbing effect can be improved, and the saturation upper limit of the wave-absorbing main board can also be improved.
