Case Study
Development of ACT’s Tekgard® brand chiller began in 2011. The initial work, approximately ten years ago, resulted in the design and manufacture of qualification units and several proof of manufacture units.
Six years later, a production contract was placed for tens of units to replace chillers manufactured by another supplier. Shortly after production started, the build was halted.
ACT was contacted and - Field experience gained with the original units and the first generation Tekgard® units made clear the design was inadequate to provide the desired level of ruggedness and reliability required for the severity of the field conditions that the original units were designed for. The production program was paused and ACT engaged in a significant redesign and requalification effort to address the design shortcomings of the original units they had specified the production units from.
Read the full case study to learn how the ACT team overcame the challenges of designing to the most stringent of military requirements they had seen in over 20 years.
Military electronics have some of the most stringent requirements when you combine the total power of the devices and the environment they will experience over the course of missions. Unlike most other high-power computing applications, military electronics need to withstand shock, vibration, humidity, salt, fog, dust debris and extremely high-temperature environments. Coupling these thermal and mechanical (must-have) requirements with the ongoing SWaP goals of military systems makes it extremely challenging for design engineers to properly develop a thermal solution, predict performance and sustain cost-effective manufacturing.
