“…Most of the commercial cooling plates are manufactured in diverse ways using CNC processes [42]. For example, exposed tube cold plate [43], [44] has low cost and suitable for mass production, but the cold plate could not be optimized in a wide range because of tube bending radius limitations. Another approach is an aluminum extrusion [45].…”

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.

“…To test the thermal enactment of the IGBT, they utilized thermal interface materials (TIM) and liquid (singlephase/two-phase). Their research concluded that the combination of two-phase liquid and heat transfer material improved the power module's thermal performance by 13% [24]. Chen et al investigated a new cooling system consisting of a heat sink with a vapor chamber to control the temperature of the IGBT.…”

Keeping the operating temperature in the allowable range of the power module, under a very high heat flux, is of particular importance in the performance of the systems and their reliability. In this investigation, as a new approach, a new hybrid thermal heat sink consisting of phase change material with different arrangement and mass flow rates has been used for cooling an Insulatedgate bipolar transistor. As an innovation, to reduce the operating temperature of the power module at a heat flux of 100 W/cm2, the paraffin and Metal-based PCM have been applied in the water cooling chamber and simulated simultaneously. The finite volume method and piezo algorithm was used to solve the governing equations. Then, the effect of the flow rate and arrangement of PCMs on temperature variations of the power module has been examined in terms of time. The melting process of the PCM was numerically simulated by the enthalpy-porosity method in threedimensional computational domain. The results revealed that using the metal-based PCM compared to paraffin due to its high thermal conductivity increased the heat transfer rate. As a result, the operating temperature of the power module decreased. Also, metal-based PCM in 4 different arrangements (A,B,C,D) performs better than the conventional cooling system. Finally, it reduced the operating temperature of the power module. Based on the results obtained at flow rates of 0.0025, 0.00375, and 0.005 kg/s, arrangement Case D showed the best performance by reducing 3 °C compared to the pure working fluid in the power module.
