High-speed airflow through type air-cooled heat dissipation airborne antenna

Abstract

A high-speed airflow through type air-cooled heat dissipation airborne antenna disclosed by the invention is resistant to a severe environment and high in heat dissipation efficiency. According to the technical scheme, a fairing and a radome define a closed space for protecting an antenna body, and the fairing is in smooth transition connection with the radome through an outer wall ring of a carrier plate; an air inlet area is designed at the front end of the carrier plate along the heading direction, and the antenna body is embedded in the rectangular concave cavity of the carrier plate through a middle rectangular concave cavity and a rear end air exhaust area and is buckled on the upper surface of the concave cavity of the carrier plate to form a heat dissipation functional area; and an antenna body is embedded into the concave cavity of the carrier plate and is provided with strip-shaped heat dissipation teeth along the course, heat generated by the antenna is conducted to the heat dissipation teeth of the antenna, the heat is taken away by blowing airflow generated in the high-altitude flight process of an aerial carrier, and high-speed cold air entering from air inlets in the left side and the right side of the inclined front end of the course converges at the rear end of the air inlet area, flows through the heat dissipation air channel and is discharged from the air outlet, and the air directly blows the surfaces of the heat dissipation teeth to discharge the heat dissipated by the antenna to the atmosphere.

Description

technical field [0001] The invention belongs to the field of heat dissipation of avionics electronic equipment, and in particular relates to an air-cooled heat dissipation channel of an airborne antenna, flow monitoring of an air inlet and a deicing device. Background technique [0002] The chip of the T / R component is the main heating element of the phased array antenna and the main object of temperature control. As the main heat source of active phased array antenna, T / R component is the core content of thermal design of active phased array antenna. Array temperature control is one of the key technologies in phased array antenna structure design. Since multiple T / R components are arranged inside the antenna, they are arranged compactly and have a small heat dissipation space, which makes the heat flux density of the antenna very high. If the heat cannot be taken away from the antenna front in time, the temperature of the antenna will rise, causing T The performance of th...
