Standards-based technology liquid cooling

Parker Hannifin in Cleveland built an advanced standards-based technology liquid cooling demonstrator for high-power embedded electronics applications to support manufacturers and users of open-system architectures. Designed with the defense and aerospace communities in mind, the product being demonstrated is called a liquid flow-through (LFT) electronics chassis. The packaging for the LFT demonstrator chassis is an air-transport rack (1-ATR long) standard-size enclosure of approximately 8 by 10 by 20.1 inches. The system is self-contained, with its own closed-loop liquid-cooling system. The system contains coolant, a control system, smart pump, filter, accumulator, heaters for cold-system startup, and three different board-level heat-absorbing technologies to demonstrate the variety of options available to the electronics designer. Parker’s LFT chassis is capable of cooling as much as 850 watts per slot, a total of 2,000 watts with dielectric fluids such as hydrofluoroethers (HFE) and synthetic oil (PAO), or 4,000 watts with non-dielectric fluids such as water or water/glycol mixtures. The product can be scaled to accommodate the required amount of technology integration for individual applications, and is hybrid-backplane capable to accommodate any board technology, including VME, VITA 41/VXS, and VITA 46-48/VPX (REDI). It is designed to be two-level maintenance compatible. The user can easily change out both the major components of the cooling system and electronic modules in the chassis without the need for special conditions, tools, or specialized technical knowledge.
