Tips for Sizing Heat Sinks

Design engineers may find this article from heatsink calculator helpful in estimating the required size of heat sinks. Notably, one of their assumptions is “the source is in perfect contact with the base of the heat sink”. Thus, the need for precision on the machining of the base.

Flatness and surface finish are critical to the performance of a heat sink because of the heat transfer efficiency from the heat source to the heat sink.

We share this information with you in an effort to help you have a successful and quality heat sink design. We would enjoy the opportunity to machine and manufacture your quality heat sink.
