LIQUID COOLING DEVICE FOR APAA TRANSMIT-RECEIVE MODULES Russian patent published in 2023 - IPC H01Q1/02 G12B15/02 H05K7/20 

FIELD: cooling devices.

SUBSTANCE: cooling devices with circulating liquid intended for cooling transmit-receive modules (TRM) in an active phased array antenna (APAA). A cooling device is proposed, containing: a frame (1), in the upper and lower ribs (5), (6) of which pipelines are made in the form of channels (2), (3) for supplying and discharging coolant with inlet and outlet openings (7), (8). In the right and left parts of the channel of the upper rib (5) of the frame (1) there is a distributor (14), the internal channels (16) of which are made of variable diameter, and the distributors (14) are made with holes (15) located coaxially with the outlet holes (18) channel (2) of the upper rib (5) of the frame (1), into which inlet pipes (11) are installed, connected to the inputs of the heat removal channels (12) of the transmit-receive modules (4). The outputs of the heat removal channels (12) of the transmit-receive modules (4) are connected to the output pipes (13) installed in the inlets (19) of the channel (3) of the lower rib of the frame (1).

EFFECT: ensuring the thermal conditions of the APAA with TRMs of different power and preventing overheating of the TRM by distributing the coolant in accordance with the required flow rates for each TRM.
