MOUNTING AND COOLING
The ability of the drive to output current at a particular ambient temperature is greatly affected by the way it is mounted and the way that air circulates
across the heatplate which is the primary path for heat flow between the internal transistors and the environment. Thermal resistance is a measure of the
temperature difference between the transistors and the environment per Watt of power dissipation. The data on this page show the thermal resistance
under different mounting and cooling configurations.
INFINITE HEATSINK
The mounting surface is large enough so that its
temperature does not change when absorbing the heat
from the drive. Thermal grease is applied to the drive
heatplate.
FAN COOLED HEATSINK
A fan is mounted close to the heatsink and air velocity
is ~400 LFM (~2 m/s).
FAN COOLED, NO HEATSINK
Forced-air at 400 LFM (Linear Feet/Minute) directed at
the heatplate.
HEATSINK, CONVECTION COOLED
A heatsink is mounted to the heatplate and is exposed
for convection cooling but is not fan cooled or in contact
with a heat sinking surface.
NO HEATSINK OR FAN, CONVECTION COOLED
The heatplate is exposed for convection cooling but is
not fan cooled or in contact with a heat sinking surface.
