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...]
Book Review of Electronics Cooling (2016)
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling Online Electronics cooling engineers and designers are used to one constant in their professional lives: change. Most of it (as far as problem solving is concerned) is change for the worse… and is challenging! The heat flux keeps increasing, the geometries keep shrinking, the available solution … [Read more...]
