by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling Online Earlier in August of this year, Electronics Cooling featured an article on energy efficiency of data centers where a review of the energy consumed by the IT and non-IT equipment and its optimization by deterministic (DCIM) and AI methods (Google’s Deepmind) was presented. The … [Read more...]
First Thermoelectric Air Conditioner with Universal Input
A unique feature is included in TECA’s newest enclosure cooler series. The AHP-2259 Series of thermoelectric air conditioners will automatically accept 90 to 264 VRMS input. There are no adjustments to be made by the end user, the AHP-2259 coolers have a universal input power supply. This allows for increased versatility of use. The coolers can meet a wide range of input … [Read more...]
Controlling Device for Rotational Speed of Fans with PWM Control
Sanyo Denki has released the “San Ace PWM Controller”, a device for controlling the rotational speed of fans that have PWM control function. The controller’s main features include: reduced system power consumption and fan noise, the ability to be common-powered by the fan power supply of rated voltage 12, 24, and 48 VDC (with no separate supply required), and having a maximum … [Read more...]
Calculation Corner: Spreadsheet-based Matrix Analysis – Extension to Transient Analysis
by Ross Wilcoxon, Ph.D., Associate Technical Editor Over the years, a number of articles [1-3] published in ElectronicsCooling have described the use of thermal resistance networks to analyze electronic systems. The analysis of a thermal resistance network begins by defining discrete nodes that are connected with resistors, with the magnitude of a flow between nodes defined … [Read more...]
High-Performance Circuit Materials Exhibited at Upcoming Conference
Rogers Corporation will exhibit its high-performance circuit materials at the PCB West 2016 Conference and Exhibition, booth 201. Designed to dissipate heat in high-power applications, thermally enhanced 92ML laminates and prepregs are halogen-free, flame-retardant, thermally conductive epoxy-based thermoset materials that provide a lead-free-solder-compatible solution for … [Read more...]
