Boyd’s Solution Including a Counter Intuitive Reduction of Heat Sink Size Solved Customer’s Tablet Temperature Problem
Introduction
A major contract electronics manufacturer (CEM) chose BOYD, to
evaluate the thermal performance of a ruggedized tablet PC in order to
reduce the skin temperature of the product.
Challenge
Reduce the skin temperature and still maintain the component temperatures within operating limits.
The system had to be isolated from outside air and dust.
Due to the small product form factor, it had to be cooled using natural convection.
Solution
Boyd characterized the air flow and temperature profile of the
enclosure using CFD. The resulting CFD model was used to identify critical
components and product zones that needed improvement. The size of the
heat sinks for the hottest components was reduced to decrease radiant
heat transfer from the heat sinks to the external enclosure.
The hot spot regions were isolated from the external enclosure using insulation at several locations:
• A plastic cover was added over the hot spots to separate the heat sources from the side wall of the enclosure.
• Polycarbonate sheet was added for thermal insulation between the PCB and a magnesium plate that houses the processor.
• Silicone sealant was added between the heat sink base and the magnesium plate.
•
An RF gasket was added around the interface between the heat sink and
the processor to act both as thermal insulation and EMI shielding.
The Deliverables/Results
Boyd’s solution solved the customer’s tablet temperature problem. The solution included a counter intuitive reduction of heat sink size. Boyd’s expertise provided a cost-effective alternative to a customer that had no need for full time thermal engineering.

Boyd Thermal Management Solution Using CFD Analysis and High Density Casting Process for Laser Light Sources
Heat flows from the device to the base plate then to the heat sink, gets sucked by the fans and eventually released in ambient air. The thermal target was very tight and the geometry required an advanced casting solution. While the thermal target for this design had to be adjusted due to physical constrains, the California team of Boyd, was able to assist with finding the best thermal management solution using CFD analysis and high density casting process.
