Processing speed continues to grow along with miniaturization, which reduces processor footprints but increases heat loads. With faster processing speeds, demand for electrical power (amperage and or voltage) continues to rise. While computer rack space remains unchanged and circuit density is increasing, efficient waste heat elimination is critical to prevent harm to components.
With the introduction of more heat comes more resistance, and with more resistance, more heat. This creates a possible negative feedback loop, resulting in potential thermal runaway.
In the past, processor cooling was performed via convection: fans circulated air over heatsinks, keeping temperatures down. As datacenter sizes grow, convection has become problematic due to the space it requires. Air is also less efficient at conducting heat than liquid. Conductive liquid cooling outperforms traditional air cooling, requires less energy, and produces much less noise than fan cooling.
A variety of different liquid cooling options have been explored and implemented:
The choice of liquid cooling method depends on the specific needs and requirements of the system, such as the size, power density, and performance requirements.
A variety of dielectric fluids exist, with brand names like 3M and Shell offering eco-friendly options. With the increased adoption of liquid cooling, material compatibility has become an ongoing conversation.
The Anderson Power connectors can support high current DC, and its Saf-D-Grid connector series is rated for up to 600V AC/DC disconnect and 400V AC/DC hot-plug while delivering up to 30A UL and 32A IEC within the standard IEC 60320 C13 footprint. Materials used in these connectors are typically compatible with many of the dielectric fluids currently employed. This compatibility coupled with the higher thermal rating of Saf-D-Grid versus a standard appliance connector offers flexibility and a major value proposition for systems that implement liquid cooling or require more thermal tolerance in a compact footprint. The Saf-D-Grid empowers datacenter engineers to satisfy the power demands required in the limited space provided for power connections.
The conversation about liquid cooling continues to be a hot topic in the industry, driven by a few key factors:
The future of data center scalability is likely to involve continued growth and increased adoption of liquid cooling technologies. With the increasing demand for high-performance computing and data storage, liquid cooling will be an important solution for managing the heat generated by the growing amount of power consumed in data centers.
