Daat's 25th anniversary marks a truly unique milestone that most companies never reach. Over
the past 25 years, Daat has created a legacy - the unique Coolit-family of CFD software for
electronics cooling that helped fuel the development of ever hotter and more complex
electronics. The Coolit's award-winning intuitive interface put new users in charge within
hours of installation. Occasional users loved it too: no retraining was required. As a result
CFD, once the domain of PhDs with supercomputers, became the tool of engineers with a laptop
and an undergraduate-level knowledge of fluid mechanics and thermal analysis.
We have accomplished a lot during the past 25 years in large part thanks to you, our
customers. Your needs and feedback guided our development efforts. In the years to come, we
promise to continue serving your needs and striving to bring you the very best. Here's a small
sample of feedback we received from you.
Coolit really is easy-to-use. The whole process is very, very visual and
Despite being a first time Coolit user, I quickly mastered the software. Coolit's
user-friendly interface made it easy to quickly ramp-up my modeling skills.
Coolit is specifically designed for electronics applications and it is
incredibly easy to set up a model and get an answer. By catching problems early in the design
cycle, we save tens of thousands of dollars and avoid months of delay.
We calculated over 60 complex models, studying the impact of component placement, fan
properties, and vent properties, sizes, and locations. In the end, more than one design
parameter combination met the specifications and we were able to supply the customer with
several workable designs from which to select based on manufacturing costs, aesthetics, or
With Coolit, I could start a new model from scratch, have it up and
running, and deliver results in the same day. The software was at least five times faster than
what we had used.
You can pick up Coolit after 6 months of non-use and start building your
model; there is no re-learning curve.
We designed several experiments for single and multicomponent PCBs to be
used against CFD predictions. All experiments were carefully instrumented to eliminate
potential uncertainties. CFD calculations by people who did not know results of measurements
to guard against experimenter bias. Coolit predictions were within 1% of the measured.
It only took me one day to create a model for a large card cage; it would
have taken 3-4 times that with other packages we used.
Throughout the design process Coolit's ease-of-use proved crucial. The
electronics engineers who undertook the thermal design had no training in CFD. But Coolit's
intuitive interface quickly helped the designers get up to speed.
CoolitDC requires only a laptop and is 10x faster and just as accurate as
CFD packages run on much larger computers. It is ideal for applications requiring numerous
Coolit rapidly calculates "what if" scenarios and identifies the best case
configuration in a fraction of the normal design time. When test data were compared against
the Coolit predictions, the results were within 5%." In some cases, prototypes are eliminated
To minimize the design safety factor and hence the cost and critically
important weight of satellite communication equipment, Coolit predictions were benchmarked
against experiment. Experimental measurements taken every 60 seconds over 4 hours. The
predicted temperatures matched measured to within 3%. Such accuracy is expected to eliminate
several design iterations per each new design and reap significant savings in development time
The benchmark test not only confirmed the accuracy of Coolit's predictions,
but also demonstrated the software's excellent performance in analyzing complex designs. The
results identified the optimum airflow design and confirmed that both designs would not exceed
their temperature limits.
With Coolit you can save weeks, if not months of work, depending on the
complexity of the design and how intuitive you are in developing the initial cooling
By eliminating physical prototyping Coolit shaved over 25% off the development cycle: 3-4
weeks off the 12 week cycle.
Since adopting Coolit, the company has begun simulating even inexpensive components it
previously could not economically justify analyzing. This new information has resulted in more
reliable and better-performing designs. This allowed us to reduce reliance on physical
prototypes and with an accompanying reduction in product development time and costs.
We greatly value Coolit's exceptionally short learning curve. Our group does not have a
dedicated thermal designer, and when a new project comes along, engineers can start using the
software immediately - no training or retraining is required.
