Description

Technical Field

[0001] The utility model belongs to the technical field of radar shortwave receivers, and in particular relates to a chassis with a hidden heat dissipation window. Background Art

[0002] As radio communications and radar technologies are changing with each passing day, radar shortwave receiver technology has also developed rapidly. Due to the comprehensive integration requirements of secondary radar, the receiver design has gradually changed from the original single-channel and single-function to multi-channel and multi-function.

[0003] In the prior art, when a radar shortwave receiver is in use, ventilation holes are generally opened on the chassis and a cooling fan is installed to dissipate heat inside. The cooling efficiency of the ventilation holes is low. Although the cooling fan has a good cooling effect, it lacks a dustproof component, so that when the cooling fan is working, dust from the outside will be brought into the chassis, causing pollution and damage to internal electronic components. Therefore, we propose a chassis with a hidden heat dissipation window. Utility Model Content

[0006] Furthermore, mounting seats are provided on both sides of the window and at the bottom of the filter dust screen.

[0007] Furthermore, the tops of the mounting seats on both sides are provided with limited clamping grooves.

[0008] Furthermore, both sides of the bottom of the filtering dust shield are provided with limit clamping blocks corresponding to the positions of the limit clamping grooves.
