A company headquartered in California uses visual collaboration
cloud where teams across the globe can create, share and
innovate. The technology used is more than video conferencing
and webinars. Prysm Inc. combines apps, content, video and the
web into a single interface for data visualization.
Prsym Inc. began developing a new product using laser light sources. The laser sources are mounted on a base plate which is further mounted on a heat sink with fans. 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 Aavid, Thermal division of Boyd Corporation, was able to assist with finding the best thermal management solution using CFD analysis and high density casting process known as HDDC.
The analysis began by creating a thermal simulation model of a
baseline concept which uses the fans and heat sinks tested by
Prysm Inc. This particular array of laser sources would be under
conditions such as forced convection and used at an altitude of
3000m above sea level. Aavid’s team designed and optimized a
heat sink to decrease the maximum temperature on the lasers.
Offering the best thermal management solution for cooling these
laser sources will not only help to perform better, but the lifetime
will be longer. Multiple simulations were ran to find the most
In temperatures of 104 degrees Fahrenheit, the temperature drop across the base plate and ambient was approximately 43 degrees Fahrenheit. To further improve the thermal system performance, Aavid suggested bringing the fans closer to the base, and adding partitions between the two fans.
We at Aavid, helped to provide the best possible solution for a heat sink for Prysm’s video walls.
