Abstract
In this work, an innovative aluminum liquid cold plate for press-pack power applications with an internal finned geometry made with additive manufacturing is proposed and analyzed. Thermal and fluid dynamic performances are estimated by FEM simulations, which have been validated through an ad hoc test bench. Proper considerations about potential problems of the selective laser melting metal printing technique and their implications for the reliability of liquid cold plates have been done. Then, simulation results for failure conditions (short circuit and coolant liquid circuit failure cases) on a complete press-pack stack are shown.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
