Abstract This paper summarized the heat problem and water cooling technology of HVDC converter valve, and presented applying evaporative cooling technology to HVDC field. A model was designed for the 5-inch thyristors, composed of a wall-type evaporator, gas collecting pipe, liquid tube and condenser, etc. Based on this model, the temperature fields of the thyristors in different power conditions are calculated by FEM. The percentage error between simulation data and experimental result is under 8%. And the results have verified the accuracy of the calculation and test. Studies have shown that the application of evaporative cooling technology makes the temperature distribution of thyristors more uniform, and the increasing of cooling margin can guarantee the current-carrying capacity of HVDC converter valve unit. These results will offer theoretical and design support for using of evaporative cooling technology in HVDC station.

Key words： Evaporative cooling high voltage DC converter valve thyristors simulation experimental study
