6.4. Example 4: Heat Sink Selection
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.)
