The first commercially available computer system that is cooled with hot water rather than air was unveiled at the Leibniz Supercomputer Centre in Munich. The IBM iDataplex system removes heat 4,000 times more efficiently than air-cooled systems using a new form of IBM’s hot-water cooling technology. It cools active components in the system such as processors and memory modules … [Read more...]
Spray Cooling Heat Transfer – Test and CFD Analysis
Spray cooling processes yield high heat transfer coefficients due to heat absorption associated with latent heat absorption during liquid-vapor phase transition [1-5]. Spray cooling advantages lie in potentially eliminating TIM1 and TIM 2 thermal resistances, yielding significant reduction in overall thermal resistance. Due to the complexity and chaotic nature of millions of … [Read more...]
Designing Heat Sinks When a Target Pressure Drop and Flow Rate is Known
Forced convention air cooled heat sinks and liquid cooled cold plates are quite pervasive in their use in electronics cooling applications. While there can be significant debate on whether to air or liquid cool a particular component, the approach a thermal engineer would adopt to design both components is essentially similar. Parallel plate fins are the most common geometry … [Read more...]
New Thermo-Fluid Simulation Software for Power and Energy Markets
Mentor Graphics Corporation announced the Flowmaster(R) Power and Energy version for system level thermo-fluid simulation. This new product provides a two-phase solution modeling the phase change from liquid to vapor for steam generation or from vapor to liquid when steam is consumed. The software introduces a complete steam/water Rankine Cycle simulation capability for the … [Read more...]
U.S. Navy Incorporates New Test Equipment Products
National Instruments announced that Lockheed Martin will integrate NI PXI modular instrumentation and platform products into the U.S. Navy’s electronic Consolidated Automated Support System (eCASS) automated test equipment family. The eCASS test stations replace the existing CASS program as the U.S. Navy’s core test system for on-ship and onshore electronic subassembly … [Read more...]
