Codec Air Cooling System Case Study
Introduction
Challenge
Our analysis of the system found several high power components would overheat without increased heat dissipation. Airflow was bypassing a critical area of the system, causing thermal problems for several components. Components downstream in the airflow path were seeing preheated air and low air velocities.
Solution
Aavid created a CFD model to characterize the air flow and temperature profile of the system. The critical components and product zones were then identified from the model. A customized baffle was designed for the cooling air intake to minimize air bypass and direct the airflow over the thermally critical components. Optimized heat sinks were designed for the thermally critical components to reduce their junction temperatures to an acceptable level.
Implementation
Cisco Systems implemented Aavid’s thermal solution to help cool their TelePresense video conferencing product. By providing a solution Aavid was able to ensure businesses across the world were able to maintain communications and hold meetings when being physically present was not available.
Results
The Aavid solution optimized air flow through the system to maximize heat dissipation of critical components, giving the customer higher system reliability. The cooling solution gave the customer new design options for system upgrades and to increase performance in the next product generation.
