Graphite mining and exploration company Focus Graphite Inc. has announced a joint venture development agreement on behalf of Grafoid Inc. with CapTherm Systems Inc., a developer of cooling technologies for high-power electronics, to develop and commercialize next-generation, multiphase thermal management systems for electric vehicle (EV) battery and light emitting diode (LED) … [Read more...]
Nanocrystal Arrays May Provide Energy Efficient, Low Cost Replacement for Single-Crystal Semiconductors
A team of researchers from Carnegie Mellon University and the University of Chicago are in the process of exploring how heat is transported in organic-inorganic hybrid materials by examining thermally-related behavior of nanocrystal arrays, in an effort to identify whether they could be an effective, low-cost replacement for single-crystal semiconductors in solar cells, … [Read more...]
Thermal Facts & Fairy Tales: Are Critical Heat Fluxes of LEDs and ICs Comparable?
Author Clemens J.M. Lasance, Guest Editor Fact: many papers discussing LED thermal management issues report values of about 100 W/cm2 and use the same arguments that are valid for ICs to demonstrate that some critical value has been reached. The question to be addressed: is this indeed a fact, or can it be shown to be a fairy tale, and hence do we need different … [Read more...]
New High Bay LED Cooler Is Smaller and Lighter Than Passive Cooling Equivalents
Nuventix, Inc. has introduced the LED Cooler R150-170, a new high bay LED cooler that, according to the company, is “33 percent smaller and 60 percent lighter than passive cooling equivalents used in industrial high bay fixtures.” The announcement was made at the Strategies in Light show held on February 12-14 in in Santa Clara, Calif. The R150-170 is capable of “exceptional … [Read more...]
Thermal Management PCB for Use with LEDs
Thermal management company SinkPAD has announced the release of the SinkPAD Star PCB for use with the new Luxeon-T and Cree MK-R LEDs. The new thermal management PCB will be on display at the Strategies in Light Show in Santa Clara, Calif. in mid-February. According to the company, the SinkPAD Star PCB conducts heat out of the LED system by “creating a direct thermal path … [Read more...]
