[Abstract]:The electromagnetic detection method of controllable source needs high power transmitting system as artificial field source. The loss up to kilowatts produced by the transmitting system is studied, and the reasonable loss analysis and heat dissipation design of the transmitting system are carried out. In order to ensure long-term stable operation of the launch system. According to the technical index of the electric source emission system, this paper calculates the loss of the DC power supply, the steady current circuit and the output bridge of the transmission system, and makes a theoretical analysis and an example design of the heat dissipation system. Including the establishment of the heat resistance model of the radiator and the design of the air-cooled heat dissipation system in order to ensure the long-term stable operation of the emission system under the conditions of high voltage and large current.
