“…Another way to neglect mentioned limitations is to Anchor Support use 3D polymer printing where possible, as 3D polymer printing limitations are different due to lower material weight compared to metal. In the case of direct liquid cooling, as the power modules are in direct contact with the coolant, it is possible to print a polymer heat sink and limit heat dissipation by contact area in of the heated surface with the liquid coolant [69]. For indirect liquid cooling a polymer cold plate and heat sink are not compatible solutions as the heat dissipation occurs through the cold plate wall.…”

Modern Electric Vehicles (EVs) require high power and high efficient powertrains to extend their power range. A key element of the electric powertrain is its drive with an electric machine controlled by a traction inverter. A cooling system dissipates heat generated due to the losses in this inverter and keeps its temperature within limits, i.e. below the operational maximum value. Indirect cooling systems are often the preferred solution due to their easy implementation and robust separation of the electric/electronic parts and the coolant circuit. Indirect cooling comes with additional surface interfaces, hence thermal barriers and increased thermal resistance for the losses' heat flow path. One way to increase the system's heat transfer coefficient is by implementing power electronics with dual-sided cooling (DSC) solutions and by enhancing surface structures for the cold plates. Manufacturing complex cold plate solutions with internal surfaceenhancing structures by way of classical techniques (e.g. aluminum extrusion with CNC machining) can be difficult, costly, or even not possible. Sealed one-piece solutions are preferred, without the need to weld parts or use screws, glue, gaskets, etc. 3D metal printing allows to manufacture of a one-unit compact, light, and reliable cold plate. This study shows the advantages and limitations of a 3D metal-printed inverter cold plate by presenting the microchannel design, numerical thermal simulations, and experimental results for the liquid cooled DSC SiC and Si inverters. This work explores the compatible use of 3D metal printing solutions, which will aid the development of modern high-power density EVs.

“…An efficient thermal model is required to improve the lifetime of the power module. In [36], a detailed step by step strategy has been outlined to reduce the temperature swing across the power module while guaranteeing the stability of the converter operation. A very high-power density 150 kW T-type traction inverter was studied using non-metallic impingement cooler and integrated to the direct baseplate.…”
