Abstract

The invention discloses a thermal control system for a plane phased array antenna with high power and high heat flow in double-side view, which includes a transmitting and receiving chip assembly and a pre-embedded area of ​​a phase-change heat pipe installed in a structural honeycomb plate, and the phase-change heat pipe adopts aluminum ammonia The phase-change heat pipe plays a role of equalizing and suppressing the temperature rise of the transmitting and receiving chip components; there is a heat-conducting filler between the transmitting and receiving chip components and the embedded heat pipe area of ​​the honeycomb plate to increase the contact heat conduction between the transmitting and receiving chip components and the phase-change heat pipe . The invention solves the problems of heat dissipation, temperature consistency, heat preservation when not working, and the like when the space-borne radar transmitting and receiving chip assembly is working under the condition of double side view, high power and high heat flow.

Description

technical field [0001] The invention relates to satellite equipment, in particular to a thermal control system for a plane phased array antenna with high power and high heat flux in double side view. Background technique [0002] The on-board transmitting and receiving chip component is the key stand-alone unit of the remote sensing satellite. Whether its working performance is normal or not directly affects the imaging quality of the remote sensing satellite; the thermal control design of the planar phased array antenna plays a decisive role in the clear and stable operation of the remote sensing satellite; Since the transmitting and receiving chip component consumes a lot of heat and works in a pulse mode, the thermal control design of the transmitting and receiving chip component is one of the keys to the thermal control subsystem. The thermal control requirements of transmitting and receiving chip components generally include three parts; [0003] Temperature range requ...
