“…This range covers the cooling methods of forced air cooling to cold plates. The convection coefficients are applied to the bottom of the base plate or heat sink, depending on the packaging layout, and are hence assumed to be effective convection coefficients [14].…”

This paper presents a way of determining the cooling requirements for a power electronic inverter controlling a traction motor in a hybrid car. The cooling requirements are determined through electro-thermal simulations. Several comparative electro-thermal simulations are carried out for different levels of cooling, i.e. convection coefficients, power module integration, switching frequencies and mission profiles. The importance of taking the thermal coupling, between devices within the power module, into account is discussed. The cooling requirements are determined both for a fixed and variable switching frequency. The results indicate that the cooling requirements can be reduced significantly by using a variable switching frequency.

“…In general, either convectional air-cooling or liquid-cooling is the available single-phase method for dissipating waste heat nowadays [3], and the latter option is more attractive due to its high thermal load ability than the former one. However, when a higher level of heat fluxes generated and face more complicated working conditions such as overload in the aeronautical environment, liquid-cooling techniques often cannot gain sufficient heat dissipation capacity and achieve a relatively stable performance [2,4].…”

This paper presents an air-oriented spray cooling system (SCS) integrated with a two-phase ejector for the thermal management system. Considering its aeronautical application, the spray nozzle in the SCS is an air-blast one. Heat transfer performance (HTP) of air-water spray cooling was studied experimentally on the basis of the ground-based test. Factors including pressure difference between water-inlet-pressure (WIP) and spray cavity one (PDWIC) and the spray volumetric flow rate (SVFR) were investigated and discussed. Under a constant operating condition, the cooling capacity can be promoted by the growth factors of the PDWIC and SVFR with the values from 51.90 kPa to 235.35 kPa and 3.91 L ⋅ h − 1 to 14.53 L ⋅ h − 1 , respectively. Under the same heating power, HTP is proportional to the two dimensionless parameters Reynolds number and Weber number due to the growth of droplet-impacting velocity and droplet size as the increasing of PDWIC or SVFR. Additionally, compared with the factor of the droplet size, the HTP is more sensitive to the variation in the droplet-impacting velocity. Based on the experimental data, an empirical experimental correlation for the prediction of the dimensionless parameter Nusselt number in the non-boiling region with the relative error of only ± 10 % was obtained based on the least square method.

Power electronics is a key technology for electric, hybrid, plug-in hybrid, and fuel cell vehicles. Typical power electronics converters used in electric drive vehicles include dc/dc converters, inverters, and battery chargers. New semiconductor materials such as silicon carbide (SiC) and novel topologies such as the Z-source inverter (ZSI) have a great deal of potential to improve the overall performance of these vehicles. In this paper, a Z-source inverter for fuel cell vehicle application is examined under three different scenarios. 1. a ZSI with Si IGBT modules, 2. a ZSI with hybrid modules, Si IGBTs/SiC Schottky diodes, and 3. a ZSI with SiC MOSFETs/SiC Schottky diodes. Then, a comparison of the three scenarios is conducted. Conduction loss, switching loss, reverse recovery loss, and efficiency are considered for comparison. A conclusion is drawn that the SiC devices can improve the inverter and inverter-motor efficiency, and reduce the system size and cost due to the low loss properties of SiC devices. A comparison between a ZSI and traditional PWM inverters with SiC devices is also presented in this paper. Based on this comparison, the Z-source inverter produces the highest efficiency.
