Radar structure with multi-cavity coupling sealing heat dissipation air channel and universal pitching supporting frame

Abstract

The invention relates to a radar structure with a multi-cavity coupling sealing heat dissipation air duct and a universal pitching support frame. Two independent air ducts are adopted, and the independent air duct I independently completes heat dissipation of a signal part, a microwave module and a wave control power supply which are low in heat consumption; and the independent air duct II independently finishes heat dissipation of the TR assembly with high heat consumption and high heat density. Due to the fact that the radar needs to have usability of frequently disassembling a rear plate, the independent air duct II needs to adopt a structural form that a unique thread pre-tightening force is matched with a sealing rope to conduct double-face pressing to solve a problem of multilayer sealing caused by a detachable multi-cavity coupling air duct. Subsystems in a radar case are attached to outer surfaces of the sealed air ducts I and II through heat conduction gaskets, heat is transmitted to the heat dissipation fins on the inner surfaces of the air ducts I and II in a heat conduction mode with low heat resistance, and heat is taken away through convection of a draught fan. Problems of integrated design and heat dissipation of each extension set of the radar in a high-heat-density environment are solved.

Description

technical field [0001] The invention belongs to the two fields of machinery and circuits, and relates to a radar structure with a multi-cavity coupling sealed cooling air duct and a general pitch support frame. Background technique [0002] A photoelectric and radar system needs to complete the detection, tracking, classification and recognition of ground personnel, vehicles and low-altitude flying targets in the reconnaissance and surveillance mission area, and measure the target distance, orientation, speed and other parameters. All-weather guarding, monitoring and control of the frontline of the border has been completed. The radar system can independently complete the directional radiation of the detection signal and target echo signal processing, target search, tracking and identification, and can also guide the photoelectric system 39 to implement joint detection. Due to the needs of reconnaissance, both photoelectricity and radar need to be able to rotate in a 360-de...

Problems solved by technology

However, due to the different heights of the radar installation positions, it is impossible to separately design pitching fixed support frames with different lengths for each different erection height
