Forced vaporization cooling of HVDC thyristor valves
Abstract
The cooling of power dissipating devices by boiling Freon R-113 was investigated. Thermohydraulic instability questions were resolved, and it is shown that the maximum (critical) heat flux available using this coolant in a forced vaporization cooling mode provides sufficient margin for semiconductor device duty cycles. Analytical predictive tools, experimental data, and empirical correlations are developed for design purposes.
