Abstract

Air-cooling method is adopted on the basis of the requirements for the thermal stability and convenient field use of an electricalsource transmitter. The power losses of the transmitter are determined after calculating the losses of the alternating current(AC)?direct current (DC) power supply, the constant-current circuit, and the output circuit. According to the analysis of thecharacteristics of a heat sink with striped fins and a fan, the engineering calculation expression of the Nusselt number and the designprocess for air-cooled dissipation are proposed. Experimental results verify that the error between calculated and measured values ofthe transmitter losses is 12.2%, which meets the error design requirements of less than 25%. Steady-state average temperature rise ofthe heat sink of the AC?DC power supply is 22 °C, which meets the design requirements of a temperature rise between 20 °C and40 °C. The transmitter has favorable thermal stability with 40 kW output power.
