6.4. Example 4: Heat Sink Selection

Consider the following example, where the PTC indicates a cooling solution with ΨCA =3.360.

An online search can identify heat sink solutions to satisfy the cooling requirement. One such solution vendor is Alpha Novatech Ltd. Their web page indicates that parts LPDM45-10BLC or LPDM-45-10BP can meet the requirement.

The thermal resistance of the selected heat sink is about 3.2° C/W at 1.5 m/s airflow. Refer to the heat sink vendor's product data sheet for product details and resistance curve.

(The published data for the heat sink cited in this example is based on a ducted wind tunnel, similar to our example set up.)
