Futuristic Fans Are Already Here
by
In today’s engineering world, the regulation
of unwanted heat is no longer a luxury. In most cases, it has now become a
center-stage consideration in the “up-front planning” phase of today’s typical
engineering project. This is due to the undesired level of heat being created
in the normal functioning of today’s electronic systems.
In recent times, significant strides in
product design (such as the dual core processor) have bucked the trend of
today’s thermal management environment. However, the demand for smarter fan
technology continues to increase. As the past shows, increasing strides in
thermal heat management are eventually met with increasing demands for faster
and more robust applications. For every stride we make in design, whether it be
in miniaturization or channel structure, an equal and (usually) opposite, heat
exuding reaction is eventually realized.
By definition, the technology and nature of
fans must and will change with the times. As recent trends have demonstrated,
the need for smaller (and sometimes larger), longer-life fans is also part of
this call from the future.
Jaro Thermal is already developing futuristic, cutting-edge
fans, which are designed for the harshest of environments. One such fan is JARO Thermal’s new waterproof, dustproof Aquas™ series of AC fans. These fans are designed to
satisfy a variety of specified waterproof parameters. As a minimum, the fans meet
the IP55 water-protection standard, which allows them to be immersed in 3 feet
of water with no ingress of moisture. Each fan maintains an operating
temperature of -10°C ~ +80°C, with a life expectancy of 50,000 hours at 40°C.
The Aquas™ series targets applications with harsh
environmental conditions and protects against direct or indirect sprays of
water, extended exposure to salt spray, or in air containing fine dust
particles. The Aquas™ series can be fitted with a
range of IP protected connectors, extended lead lengths, and threaded inserts
where installation is difficult.
Jaro Thermal is also concentrating on the manufacture of fans that employ non-conventional methods of cooling.
Optimal Thermal
Performance: Choosing The Right Fan (Up Front)
Engineers should approach the challenge of heat dissipation from the macro, systemic
level. Think of the TIM (Thermal Interface Material), heat spreader, heat sink and fan as a team that works
together. Jaro Thermal fans (for example) are
designed with this precise outline in mind.
Jaro Thermal's fans are specifically
designed for a broad range of heat transfer concepts.
- Good Thermal fans are
readily applicable and adoptable to the newest heatsink
and heatpipe technologies.
In the past, thermal management issues were considered (only) after
the components had been chosen and integrated by electrical engineers. Many
times, expensive, corrective solutions had to be found, after the fact, to make
up for poor (up front) choices.
However, this is no longer the case. As most experienced
engineers realize, critical decisions (especially as they relate to component
selection) must be addressed at the very beginning of the pre-process stage.
Regardless of end-user applications or
industries, thermal issues cut across all boundaries. The right fan choice can reduce total
system cost in many high-performance products. Jaro
Thermal realizes that the geometry and layout of the project must be optimized
up front. At the same time, Jaro Thermal realizes the
importance of proper component and package selection for the entire system.
The advantage of the new Jaro Thermal technology is a quieter and longer lasting fan.
