Liquid cooling system for high power solid state am transmitter

摘要

A liquid cooling system cools a plurality of RF power amplifiers in a high power AM broadcast transmitter. Each RF power amplifier includes a thermally conductive block to which the power transistors associated with that amplifier are mounted. The heat generated by the power transistors is conductively transferred to the thermally conductive block. A liquid cooled plate comprising a thermal block and coolant pipes running through the thermal block is also provided. The liquid cooled plate is positioned so that the thermal block is in contact with the thermally conductive block of the RF power amplifier. A pump circulates liquid coolant through the coolant pipes.
