CASE STUDIES
iTherm® Core for Engine Block Customer Case
Background information
Our customer that produces castings for the automotive industry was trying to increase the cooling rate of the core. The temperature during casting was peaking at 645°C and averaging at 420°C.
They have decided to replace the conventional core with iTherm® conformally cooled core in order to bring cooling channels closer to the critical part of the core.
Conventional core
iTherm® Core
Once in production, iTherm® Core proved to have a substantially faster cooling rate than the conventional core.

Temperature difference
at body hottest spots
ΔT=277 °C – 1 84°C = 93°C
ΔT=530 °F – 363°F = 167°F
at tip (critical zone, engineered cooling):
ΔT=277 °C – 132 °C = 145 °C
ΔT=530 °F – 270°F = 260°F

Temperature difference
at body hottest spots
ΔT=163 °C – 123°C = 40°C
ΔT=326 °F – 253°F = 73°F
at tip (critical zone)
ΔT=163 °C – 79°C = 84°C
ΔT=326 °F – 174°F = 152°F
Improvements
with iTherm® Core
Substantially lower core temperatures
Thermal management of conformally cooled iTherm® Core resulted in a 42% lower peak temperature, from 645°C to 378°C. The average temperature has dropped significantly as well, from 420°C to 258°C (-31%)
