Shielding box structure and environment experiment device

Abstract

The invention provides a shielding box structure and an environment experiment device. The shielding box structure comprises a shielding box body and a shield door arranged on the shielding box body; the shielding box body comprises a plurality of box body plates which are connected in a seamless welding way, a cavity structure comprising a box body opening is encircled by the plurality of box body plates, and the shield door is arranged on the box body opening in close way; and a plurality of waveguide apertures are uniformly arranged on the box body plate or / and the shield door. According to the technical scheme provided by the invention, interference signals can be shielded, the hot gas in the box can be rapidly discharged, so that the internal temperature of the box is consistent with the external temperature of the box rapidly.

Description

technical field [0001] The invention relates to the technical field of communication equipment testing, in particular to a shielding box structure and an environmental experiment device. Background technique [0002] In traditional technology, in order to test the performance of the product in a shielded environment, a shielded box is often formed with a metal shell and a shielded door, and the product under test is placed in the shielded box to ensure the isolation of the signal inside the box and the signal outside the box, thereby To achieve the effect of shielding the signal. The disadvantage of this shielding technology is that when testing active products, the temperature inside the box will continue to rise, but the air inside and outside the box of this shielded box cannot be freely convected, so it will affect the ambient temperature and make the test data inaccurate. With the development of shielding technology, the active heat dissipation shielding box has the he...

AI Technical Summary

Problems solved by technology

However, this active heat dissipation shielding box still has disadvantages, that is, there is only one waveguide window for ventilation at the cooling port. The temperature is exactly the same

When the product under test needs to do temperature cycle experiments in a shielded environment, the active heat dissipation shielding box has great limitations, the temperature difference between inside and outside the box is large, and the test data is inaccurate
