Abstract

The invention relates to a liquid cooling system and a liquid cooling method thereof, belongs to the technical field of phased-array antennas, and solves a problem that the temperature of an antenna array surface of a phased-array antenna in the prior art rises to influence the performance of the antenna because the heat flux density of the antenna array surface is very high. The liquid cooling system comprises an intelligent microcontroller, a liquid cooling source, a liquid inlet pipeline, a liquid return pipeline and a liquid cooling plate. The intelligent microcontroller is used for controlling the working state of the liquid cooling system; the liquid cooling source is used for providing a cooling liquid required for cooling and heat exchange; the liquid inlet pipeline is used for injecting the cooling liquid into the liquid cooling plate; the liquid return pipeline is used for recovering the cooling liquid subjected to heat exchange in the liquid cooling plate; and the liquid cooling plate is in contact with the phased-array antenna so that cooling and heat dissipation of the phased-array antenna are realized.

Description

technical field [0001] The invention relates to the technical field of phased array antennas, in particular to a liquid cooling system and a liquid 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 related to the ...
