Abstract
The present invention provides a system and corresponding method for an oil-cooled high power amplifier system, such as an inductive output tube [“IOT”]. According to one preferred embodiment, the system has an IOT, a fluid passageway in thermal contact with the IOT, an oil-based fluid within the fluid passageway such that the oil-based fluid removes thermal energy from the IOT, an oil pump connected to the fluid passageway to circulate the oil-based fluid, and an oil heat-exchanger connected to the fluid passageway for removing the thermal energy from the oil-based fluid. The IOT preferably has a multistage depressed collector, and the oil-based fluid is preferably a commercially available transformer oil. In a preferred embodiment of the present invention, the oil-heat exchanger is connected to an external heat exchanger. The external heat exchanger has a cooling fluid passageway in thermal contact with the fluid passageway. Within the cooling fluid passageway is a cooling fluid that absorbs the thermal energy from the oil-based fluid. Also connected to the cooling fluid passageway is a cooling fluid pump that circulates the cooling fluid and a cooling fluid heat exch…
