Hybrid-electric and all-electric airplanes under study by NASA, such as the X-57 Maxwell, could operate more efficiently if the overall system was better at getting rid of heat. (Source: NASA) Future hybrid-electric and all-electric airplanes will use distributed electric propulsion (DEP), relying on multiple electric motors rather than a single or handful of jet fuel-based … [Read more...]
New Cooling Plate Said to Dramatically Increase the Lifetime of High Temperature Electronics
Korea Institute of Machinery & Materials is first to develop a TGP that operates in any direction, improving cooling efficiency by modifying the surface of a porous structure. During the past decade, developments in semiconductor industries have allowed electronics such as sensors and actuators to be miniaturized so as to perform effectively in a limited space. As a … [Read more...]
Three Thermal Simulation & Test Innovations for Electronics Equipment Design
Over the last 50 years, the automotive industry has been going through huge shifts in electrification (Figure 1). And, of course, we are seeing the electric motor starting to replace the mechanical engine with the advent of Electric & Hybrid vehicles. Not surprisingly, the demand for ever higher density in a confined electronics leads to a greater and greater need to … [Read more...]
What is the Right Temperature Set Point for My Electrical Enclosure?
Cooling units are necessary for hot enclosures, but selecting the proper temperature set point for yours can mean the difference between failure and enhanced performance Electrical enclosures serve to protect electrical devices from adverse environmental influences, such as dirt, other particulates, moisture, or chemicals that could damage components. What is more, by … [Read more...]
Towards Green Technology: Modeling of a Compact Plate Heat Exchanger Condenser for Thermosyphon Cooling of Entire High Power Datacenter Racks
By Raffaele Luca Amalfi, Ph.D., Jackson Braz Marcinichen, and John Richard Thome, Ph.D. CONTEXT AND NEW COOLING TECHNOLOGY Heat dissipations of servers and their racks in datacenters are reaching ever increasing levels, breaching the economical heat removal limits of traditional air-based cooling technologies. Currently, about 40% to 45% of the total datacenter energy … [Read more...]
