UP FRONT DESIGN WORK
Efficient Thermal Management
must be reviewed and approved at the beginning of the project. Too many
times, Thermal Management is considered after the components have been chosen
and integrated by the electrical engineers. Many times, expensive solutions
have to be found, after the fact. Therefore, critical decisions, especially
as they relate to component selection, must be addressed at the very
beginning of the pre-process stage. Issues such as the circuit
layout and copper thickness often play into the required decision making of
the pre-process. OPTIMAL THERMAL PERFORMANCE: CHOOSING THE RIGHT FAN UP
FRONT Regardless of your end-user applications or industries,
these thermal issues cut across all boundaries.
Engineers should approach the
challenge of heat dissipation from the macro, systemic level. Think of the
TIM, heat spreader, heat sink and fan as a team that works together. JARO
fans are designed with this precise outlook.
By working with our staff in a
collaborative way, a significant improvement in the function and output of
products may be achieved. For example, different versions of a fan may be
better suited to the specific requirements of the customer application. By offering flexible solutions
that can be tailored to specific needs, OEMs are able to integrate into
almost any application. Sometimes a speed-controlled
fan uses 40 to 60 percent less power compared to similar a.c. fans and
controls speed more accurately. All of our fans are made to function with
this type of internal or external technology. For customers whose desired fan
speed should be based on temperature or a control signal input, this is very
important. TECHNOLOGICAL TRENDS JARO Thermal has pro-actively
foreseen the current, growing demand for increased airflow performance and
longer life. At the same time, OEMs are looking for a much quieter type of fan.
The bottom line is this. Our customers are looking for us to creatively lower
and eliminate their heat. Smart design and technological innovation are
clearly the call of the day. According to research firms, fans must be
designed for harsher, lower powered, smaller-spaced environments. New blade
designs and bearing designs are being utilized in this endeavor. By offering
a wide variety of bearings, including the Fluid Dynamic and ultra high static
series, JARO Thermal remains a world pioneer in cutting edge technology. In
addition, JARO Thermal continues to push the envelope on creativity with such
technologies as the waterproof Aquas series. Customers are also looking for
the same size fan with a higher output, says our VP. Better output can be
improved though better blade technology, a better motor, distance from blade
to the housing, he says. Another issue is long life.
It's been a big race to get to 80,000 to 100,000 hour life times, said the
VP. Jaro recently announced the release of a new fluid dynamic bearing (FDB)
fan that offers an incredible 80,000 hours of fan life. Based on Sony's FDB
bearing technology, the fan also offers lower noise and high reliability. JARO Thermal News |
