Use of Heat Sinks and Cold Plates
The DW025-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 PD is the power dissipated by the module,
θCS
represents the interfacial contact resistance between
the module and the sink, and
θSA is the sink-to-ambient
thermal impedance (°C/W). For thermal grease or foils,
a value of
θCS = 0.1 °C/W—0.3 °C/W is typical.
The required
θSA is calculated from the following equa-
tion:
θSA = [(Tc – TA)/PD] – θCS
Note that this equation assumes that all dissipated
power must be shed by the heat sink. Depending on
the user-dened application environment, a more accu-
rate model including heat transfer from the sides and
bottom of the module can be used. This equation pro-
vides a conservative estimate in such instances.
