congatec launches cooling options for 100W edge server ecosystem

Perfectly matched cooling is essential for the 100 Watt edge server ecosystem, as overheating can lead to rapid aging and system failure. Edge servers with real-time requirements also need optimum protection against thermally induced performance degradation to ensure deterministic behaviour, which further underscores the importance of high-performance cooling systems in industrial computer systems.

Andreas Bergbauer, Product Line Manager at congatec explains: "The AMD EPYC Embedded 3000 Series Processors provide a new level of high-performance computing for embedded edge server systems. But with such embedded system designs, it is critical to manage the thermal envelope of any high-performance part. That's why we've worked hard to create a 100 Watt ecosystem for high-performance COM Express modules that meets the rugged design requirements for 24/7 operation. We are now presenting three of these solutions for the first time at Embedded World 2020."

Stephen Turnbull, director of product management and business development, Embedded Solutions, AMD explains: "The AMD EPYC Embedded 3000 Series Processors allow for a wide range of embedded edge server designs. It is great to see that companies such as congatec invest in offering a complete ecosystem with Server-on-Modules and all required accessories, such as these powerful cooling solutions, which will help simplify designs and help end customers get systems faster."

The congatec cooling systems for the 100 watt ecosystem around the AMD EPYC Embedded 3000 Series Processors come in three variants, all based on the COM Express heatspreader specification that has been standardised by the PICMG, i.e. heatspreader with heatpipe adapter; heatspreader with integrated heatpipe; and an active cooling system. Together with standard COM Express heatspreaders, OEMs can now choose between four variants that cover the entire range of processor cooling options.

Heatpipe adapter for COM Express heatspreader

The conga-B7E3/HPA heatpipe adapter absorbs the waste heat from the heatspreader via up to four heatpipes and directs it, for example, towards other passive heat sinks mounted on the housing. This allows the design of powerful passively cooled systems for up to 100 Watt.

COM Express heatspreader with integrated heatpipe

The option with integrated heatpipe, with the product name conga-B7E3/HSP-HP, was developed primarily for particularly flat embedded systems where a standard height COM Express heatspreader must be coupled to the housing. Here, the integrated heatpipe distributes the waste heat from the processor evenly over the entire heatspreader so that no hotspots are created, even in applications with a TDP of up to 100 Watt.

Active cooling system for rugged 24/7 operation

The fan-based active cooling system conga-B7E3/CSA-HP is specifically designed for 24/7 operation in harsh industrial environments. In this complete cooling system for COM Express Computer-on-Modules the fans are not only mounted extra securely, but also specifically fixed to reduce wear and tear. In addition, the bearings are equipped with a special seal and additional cover to provide maximum protection for mechanics and lubricant. With a high-performance synthetic oil as lubricant, the fan has an MTBF of several decades - and this in the industrial temperature range from -45 to +85degC and with industrial-grade shock and vibration resistance. The functional scope of this fan-based active cooling system is rounded off by the additional integration of a heatpipe to distribute the waste heat from the processor even before it reaches the active fan.
