Heater；The surface spraying of cellular board and transmitting-receiving subassembly has thermal control coating；The back side of whole device is coated with
Multilayer insulation component；The front of whole device is coated with electrostatic prevention film.
The thermal controls apparatus of radar antenna transmitting-receiving subassembly of the present invention, due to using pre-buried heat pipe samming, antenna just
Surface radiation radiates to be engaged with the heating of accurate temperature controlling electric heater, and different working modes are realized by temperature controller
Switching, constitutes flexible and changeable, the thermal controls apparatus of adaptable radar antenna component, therefore solve height
It is incubated when radiating, do not work during the radar antenna transmitting-receiving subassembly work of power density pulsed operation, Yi Jiwen
The problems such as spending uniformity, achieves the beneficial effects such as the good, strong adaptability of stable temperature control, uniformity.
