Electric & Hybrid Vehicle Market

Hybrid and electric vehicles typically require liquid cooling of the power electronics in the inverter, battery, onboard charger, DC-DC converter and electric motor.  We supply all types of liquid cooling but cooling of the power electronics inside the inverter is our specialty.  The power electronics most commonly used in the inverter are Insulated-gate bipolar transistors (IGBTs).  In most applications the IGBTs switch the DC power from the batteries into 3 phase AC power to drive the vehicle’s electric motor.  In normal operation 1000s of watts of heat can be generated from the IGBT’s in the inverter. Liquid cooling is required to keep the IGBTs from overheating and ultimately failing.  Better cooling means more power and efficiency for the vehicle.

We have 4 products for the Electric & Hybrid vehicle market

Standard cold plates for IGBT modules like Infineon EconoDual, HybridPACK 1, HybridPACK Drive, Semikron Skim Modules.  Also can be used in Silicon Carbide (SiC) IGBTs like those from Wolfspeed (for use with flat bottom IGBT modules mounted to the cold plate with a thermal interface material).
MicroCool CAP™ is the same as the IGBT base plate but with a cover that has an inlet and outlet. The IGBT module/substrates can be built/soldered on to sealed and welded cold plate. The welded cold plate structure is extremely stiff and resists bending therefore leading to less stress on the IGBT substrates and power electronics.
Custom cold plates and cast inverter enclosures integrated with MTD pin fin™ friction stir welded into the floor.  For use with IGBT modules mounted to the floor of the cast enclosure using a thermal interface material.
IGBT base plates with MDT pin fin™.  For direct cooling of the IGBT module base plate using an O-ring, eliminated the thermal interface material layer, can be made out of copper, aluminum or aluminum cladded with a layer of copper.
