Laburpena: Ibilgailu elektrikoari loturiko potentzia-bihurgailuetan, korronte-dentsitate handitan (500 A ingurukoak) lan egiten duten IGBT transistoreak eta diodoak erabiltzen dira. Korronte altuak direla eta, handitu egiten dira gailu erdieroale horietan gertatzen diren kommutazio-eta kondukzio-galerak, eta ondorioz, potentzia-erdieroaleak berotu egiten dira. Moduluen efizientzia eta fidagarritasuna ziurtatzeko, beharrezkoa da hozte-sistema eraginkor eta egoki bat aukeratzea. Artikulu honetan, potentziabihurgailuen moduluen hozte-metodoak berrikusi eta eztabaidatuko dira.Hitz-gakoak: ibilgailu elektrikoa, potentzia-bihurgailua, hozte-metodoak. Abstract:The power inverter modules asociated to Electric Vehicles (EV) are equipped with IGBTs and Diodes working at high currents that can reach 500 A. The high currents increase power losses, which become in heat and reduce the efficiency of the semiconductor. To ensure high power density power inverters reliability and fiability is necessary to design very efficient cooling systems. In this paper power inverter modules different cooling options will be reviewed. Advantages and disadvantages of such systems will be highlighted.

De-rating of power electronics is a common practice in harsh environment operating conditions. Advanced cooling solutions are needed to overcome the thermal limitations and prevent the de-rating of power components. This study investigates a silicon carbide power module for 28 V DC to 300 V DC power conversion (or reverse) in military hybrid vehicle applications. A combined experimental and numerical modeling effort is reported, to accurately predict the silicon carbide switch (device) junction temperature. The results show that jet impingement cooling at the module base plate increases the module heat dissipation capability by 2.5X and 1.5X, compared to the commercial-off-the-shelf cold plate cooling and micro-channel cooling solutions respectively.

“…Investigation of recent liquid cooled power modules revealed a trend towards more intricate heatsink designs to improve the heat transfer ability in closed single [3], pin-fin geometries [4] and jet impingement techniques [5]. This trend reflects manufacturers need for ever greater semiconductor dissipation rates (in excess of 200W/cm 2 ).…”

Power switching devices in dc/dc power converters for Hybrid Electric Vehicles (HEVs) are fluid cooled. Fluid cooled heatsinks make up nearly a third of the volume and weight of DC/DC converters. The design of heatsinks in automotive applications is therefore of paramount importance in order to gain high power-to-volume and high power-toweight ratios. Literature on heatsink designs often present test results that are based on one set of input data only (e.g. fluid inlet temperature, flow rate and fluid mixture). The fluid inlet temperature and flow rate, however, can vary substantially in an automotive fluid cooled system and the heatsink may therefore not perform well. Fluctuation of theses parameters must therefore be considered in the design of fluid cooled heatsinks in order to allow optimal cooling performance under all conditions. This paper describes the design of a heatsink that is optimised for one set of parameters. The heatsink is then tested at temperature and flow rate variations to emulate the fluctuation in a vehicle cooling system.
