Use of Heat Sinks and Cold Plates
The DC025 Triple Output-Series case includes
through-threaded M3 x 0.5 mounting holes allowing
attachment of heat sinks or cold plates from either side
of the module. The mounting torque must not exceed
0.56 N/m (5 in.-lb).
The following thermal model can be used to determine
the required thermal resistance of the sink to provide
the necessary cooling:
where P
represents the interfacial contact resistance between
the module and the sink, and
thermal impedance (°C/W). For thermal greases or
foils, a value of
The required
tion:
Note that this equation assumes that all dissipated
power must be shed by the sink. Depending on the
user-defined application environment, a more accurate
model including heat transfer from the sides and rear of
the module can be used. This equation provides a con-
servative estimate in such instances.
