ShowerPower® Stack
Technology
www.danfoss.us/solar
Patented liquid cooling
technology for improved
cooling of power electronics
30% better heat transfer for
cooling IGBT’s
Liquid flow directly on IGBT
base to remove heat more
efficiently
| 16
ShowerPower® Stack Technology
Heat losses are shared between four separate units and IGBT modules will
operate with lower temperature, resulting in longer life expectancy
Danfoss ensures quality in all PCB boards and inverter modules through
designing, assembling and testing each one individually
The inverter DC link is based on film capacitors - resulting in better reliability and
a longer life while also reducing maintenance
Danfoss ensures a more reliable product by having the ability to measure and
control the temperature on each IGBT module
A quick and drip-Free disconnect for the coolant supply of the inverter module
makes maintenance quick and simple.
