AI Technical Summary

Technical Problem

The heat generated by the radar during operation is difficult to dissipate, causing heat accumulation that affects the normal operation and lifespan of the radar. At the same time, water vapor in the upper atmosphere enters the radar dome, shortening its lifespan.

Method used

The system employs a radar environmental control device that includes a shell, heat exchanger, and fan. Through independent first and second heat exchange channels and the cooperation of the fan, it utilizes external low-temperature gas for heat exchange, thereby reducing the temperature of the gas inside the cavity and preventing water vapor from entering.

Benefits of technology

It effectively reduces the internal gas temperature of the radar, ensuring its normal operation and extending its service life, while avoiding the influence of moisture. It has a simple structure and does not take up too much space.

Abstract

The application discloses a radar environment control device and an aircraft, relates to the technical field of aerospace, and is used for guaranteeing the normal work and service life of a radar on the basis of realizing the cooling of the radar. The radar environment control device comprises a shell, a radar, a heat exchanger and a fan, the shell has a cavity in the interior, and an air inlet and an air outlet which are in communication with the cavity are formed on the shell. The radar is arranged in the cavity. The heat exchanger is arranged in the cavity, the heat exchanger is formed with a first heat exchange channel and a second heat exchange channel which are independent of each other, the inlet of the first heat exchange channel is in communication with the air inlet, the outlet of the first heat exchange channel is in communication with the air outlet, and low-temperature gas outside the cavity can flow through the first heat exchange channel through the air inlet and the air outlet; the inlet and the outlet of the second heat exchange channel are both in communication with the interior of the cavity. The fan is arranged in the cavity and is located on the ventilation path of the second heat exchange channel. The radar environment control device in the application is used for detecting and tracking targets.
