Embodiment Construction

[0023] A heat dissipation device for an airborne phased array radar antenna of the present invention uses a heat dissipation method combining a liquid-cooled cold plate and a heat pipe to cool down the T / R component of the airborne phased array radar antenna.

[0024] 1. Heat pipes are embedded on the reverse side of the bottom of the T / R module box close to the power devices, and the high thermal conductivity of the heat pipes is used to achieve the purpose of equalizing the temperature of each power device inside the T / R module box, such as figure 1 shown.

[0025] 2. Use the liquid-cooled cold plate as the mounting plate on both sides of the supporting antenna to fix the T / R component box, such as figure 2 As shown, the heat generated inside the phased array radar antenna is transmitted by using the high heat transfer and liquid fluidity of the liquid-cooled cold plate, and the heat is conducted to a space that is convenient for heat dissipation by using the liquid-cooled ...

Abstract

The invention discloses an airborne phased array radar antenna radiating device, and relates to an airborne phased array radar technology. The airborne phased array radar antenna radiating device comprises heat tubes and liquid cooling cold plates. The heat tubes are embedded at the position, close to power components, of the outer lateral faces of the bottom faces T/R box bodies, a plurality of T/R box bodies are vertically superposed, the two sides of each of the plurality of T/R box bodies are respectively provided with one liquid cooling cold plate, the liquid cooling cold plates are used as installation plates which support an antenna to fix the T/R box bodies, the two liquid cooling cold plates arranged on the two sides of each T/R box body are communicated with a refrigerant storing tank, by utilization of high heat exchanging performance and liquid fluidity of the liquid cooling cold plates, heat produced inside the phased array radar antenna is spread out, liquid cooling tubes are used for conducting the heat to space where the heat is prone to dissipate, and a radiator is used for concentrated heat dissipation. The airborne phased array radar antenna radiating device solves the radiating problem of phased array radar antenna T/R components.

Description

technical field [0001] The invention relates to the technical field of airborne phased array radar. Aiming at the problem that the phased array radar antenna has a large amount of heat and it is difficult to dissipate heat, it proposes a heat dissipation method in which a liquid-cooled cold plate and a heat pipe are laid in the T / R component box to realize the phased array radar. Antenna cooling. Background technique [0002] The phased array antenna is one of the most important components in the radar, and it is also the component that generates the most heat in the radar. The T / R component box is the power module for the antenna to realize the transceiver function. As the output power of the antenna increases, the heat generated by the T / R component box also increases. In order to ensure reliable operation, corresponding heat dissipation measures must be taken. [0003] The T / R component boxes that make up the airborne phased array antenna need to have good temperature co...
