02 Water Cooling for Power Electronics
Power electronics applications require new topologies that
demand higher power densities, thus design engineers
request new and custom mechanical and thermal
solutions. Water cooling of power electronics can be
defined as a science of its own. The thermal path must be
considered from the heat source – IGBT chips and diodes
– to the final heat sink (usually ambient air).

cooling for power semiconductors and batteries in electric vehiclesPower semiconductors require maximum cooling at moderate flow rate and pressure
drop. Directly cooled chips offer the best performance, however they require proper
packaging. Micro deformed in line pin fins offer a solution with unrivalled performance.
Battery cooling presents a difficult challenge as it requires equal temperatures for all cells
with minimal pumping energy. Counter-current snake designs offer the design engineer a
suitable option to overcome these conflicting design goals.
Large cooler plates with counter-current enhanced surface extrusion fluid channels These cooler plates offer uniform temperature across and between components, i.e.
typically a temperature difference of 0,5 K/kW /component. The counter current flow
configuration offers two advantages over a diagonal (parallel flow) configuration: it
requires only half the flow (comparing at same fluid velocity) and still it achieves lower
thermal resistance.
Water Cooling for Power Electronics 03
reliable water cooling stations for heat loads from 20 kw to 2 Mw
Cooling station models are available for low and high voltage applications, in cabinets or
frame mount, with water or air cooled heat exchangers. All units feature high reliability
with long maintenance intervals of over 5 years. Other high-lights are automatic de-
aeration, small footprint, removable pump unit, leakage control, clean water, i.e. inherent
corrosion inhibition, de-ionisation to below 1 µS/cm , PLC controls, touchscreen HMI, fully
redundant systems and others.
These systems are typically employed as the core of a power electronics water cooling
system in energy transmission, marine, heavy duty industry and renewable energy
applications.
turnkey water cooling system – example solar inverter
Transporting equipment in a standard container is a must, however installation in harsh
environments favor a rooftop installation with sand trap. There is no need for air filters
and electronics can be hermetically sealed from dusty environment. Our turnkey solution
includes a prefilled cooling system, water cooler plates for IGBT modules of 140x190,
PrimePack* or EconoDUAL* format and piping. The system features automatic de-aeration,
easy installation on site and long maintenance intervals.
*Primepack and EconoDUAL are trademarks of Infineon Technologies
thermo and fluid dynamic simulation tool
A cooling system for power electronics is limited by two temperatures: maximum junction
temperature and ambient air temperature. Where the maximum junction temperature is
fixed, the heat load and sometimes allowable ambient temperature need to be optimized
for a given size or budget. Our design tool for cooler plates and heat exchangers gives
quick answers to thermo and fluid dynamic behavior of a cooling system.
Our team is looking forward to put our expertise to work for your application.
