Key thermal design ingredients for industrial grade computers.
Abstract
One of the greatest challenges for industrial computing manufacturers is to deliver products that meet industrial standards and operate in harsh environments. This challenge is made even greater due to the fact that industrial users prefer the reliability of devices that do not use fans and cables. This makes matters more difficult and imposes additional hardware layout and component selection restrictions, leading to a higher production cost. Intelligent thermal design makes it possible to overcome these limitations and ensure industrial grade quality and standards. With a solid thermal design, an industrial computer will dissipate heat more efficiently and demonstrate a wider operating temperature in rigorous chamber tests. This white paper explores the major ingredients that contribute to an intelligent, efficient thermal design in industrial grade computers.
Moxa’s V2101 computer is an excellent example of how all of the thermal design strategies outlined in this white paper combine to create a computer with a wide operating temperature. The hardware and layout designers carefully selected components that would meet wide temperature requirements, and arranged the board and chipset layout to optimise heat dissipation. The product was then rigorously tested in a forced-convection thermal chamber that created a cold and snowy environment which closely resembles the actual environmental conditions of industrial applications. Then, it was tested in a natural-convection thermal chamber that simulated a hot, windless environment.
Finally, the V2101 was subjected to harrowing worst-case scenario testing. The product was first heated for eight hours, then subjected to four hours of fluctuating extremely high temperature that sometimes exceeded the target temperature, and then finally exposed to one hour of operation at the target high temperature. This rigorous testing ensures a high level of system reliability.

The maritime industry is moving through one of the most important transformations in its history. Ships that once operated as collections of independent systems are now evolving into integrated digital ecosystems, where navigation, monitoring and control systems must exchange a constant flow of data. At the heart of this transformation lies the IEC 61162 family of standards.
