Abstract

The invention relates to a liquid cooling device for cooling an antenna and a cooling method thereof, belongs to the technical field of phased-array antennas, and solves the problem that the performance of the antenna is influenced by temperature rise of an antenna array surface due to high heat flux density of the antenna array surface of the phased-array antenna in the prior art. The liquid cooling device for cooling the antenna comprises a liquid cooling plate, a first liquid cooling pipe and a second liquid cooling pipe, the phased-array antenna is installed on the liquid cooling plate and dissipates heat through the liquid cooling plate; the liquid cooling pipe is provided with an internal cavity, and the internal cavity is used for circulating cooling liquid; the first liquid cooling pipe is used for injecting cooling liquid into the liquid cooling plate; and the second liquid cooling pipe is used for recovering the cooling liquid after heat exchange. According to the invention, the liquid cooling circulation heat dissipation of the phased-array antenna is realized.

Description

technical field [0001] The invention relates to the technical field of phased array antennas, in particular to a liquid cooling device for antenna cooling and a cooling method thereof. Background technique [0002] Active phased array antennas are more and more widely used in military and civilian applications, and hundreds or thousands of T / R components are distributed on one antenna array. In the aircraft environment, they are compactly arranged, have a small heat dissipation space, and have a high degree of system integration coupling, which makes the heat flux density of the antenna array very high. If the heat cannot be taken away from the antenna array in time, the temperature of the antenna array will rise. It will cause the performance of T / R components to degrade or even fail, which will affect the electrical performance of the antenna and lead to the deterioration of radar performance. Therefore, the thermal design of the active phased array antenna is directly re...
