JMC Products - Thermal Design News from JMC: January & February 2003

November & December 2002

Happy New Year from JMC's Thermal Design News. Read ahead to see what's happening in thermal design at JMC in 2003.
Effective Thermal Management using Heat Pipe Solutions Heat pipes have an effective thermal conductivity many thousands of times as that of copper. With a goal of reaching a thermal resistance of 0.24°C/Watt, and below 0.20°C/Watt, JMC's engineering team is designing advanced heat pipe cooling solutions for future Intel® Pentium® 4 processors running at speeds above 3.06GHz. 40 CFM Copper Insert in Base Copper Fin Design Two 6mm Heat Pipes with a Grooved Wick Structure 560 Grams 3.5"x2.5"x3" Custom Sizes Available
Improved Acoustics - View our Demonstration Last month we introduced you to Panther technology, our latest fan design that performs at a high frequency pulse that is above the audible range for human hearing. This technology is available in all JMC DC fan sizes, and is available in 3 speed control options: 1. Thermistor Control 2. Voltage Variation 3. PWM to High Frequency Pulse Take a minute to watch Abe Arredondo PE, our Engineering Manager, demonstrate how quiet the Panther fan performs.

Engineering Lab Tools at JMC Read ahead to learn about a few of the lab tools we utilize that enable us to provide comprehensive thermal analyses to our customers. Computational Fluid Dynamics (CFD) Software: CFD software gives our engineers the capability to analyze and optimize blade designs for fans and blowers, perform airflow and system level analysis, and evaluate heat sink designs to determine optimum fan and heat sink combinations. Higher-level analyses can also be performed for future designs involving two-phase flows and other high-end applications. Infrared Camera: The IR camera allows JMC to take real-time, color thermal images that can be captured to a computer. With this image captured, JMC can locate critical hot spots that will require cooling.
