HEAT SINK COOLING
T H E R M A L P R O D U C T S, I N C.
FOR IGBT MODULES
6-PASS COLD PLATE
Aavid offers several methods for cooling
IGBT modules – cold plates, extruded alu-
minum heat sinks, bonded fin heat sinks,
and fan cooled modules.
6-pass liquid-cooled cold plates offer optimum ther-
mal management for high power IGBT modules.They
are ideal for use in stationary or mobile applications
requiring high power dissipation and low thermal
resistance – welding, plasma, UPS/power supplies, and
motor controls in traction and electric vehicles.
FEATURES:
• Maximizes cooling in a compact package
• Fits all standard IGBT module sizes
• Maintains uniform temperature under devices
• Available in multiple lengths for single and three-
phase design
