DESIGN OPTIMIZATION
humidity, adjacent heat loads,
and natural convection.
At first, thermofin GmbH
believed that their customer
would need to use five
heat exchangers in order
to get an even amount of
air distribution within the
storage room.

After simulating a room
with five devices, Heik noticed
a problem. " The backflow of
the air would partly bypass
into the intermediate ceiling, "
said Heik. To fix this issue, Heik
simulated some air-guiding
veins in the room, which
would help ensure a smooth
backflow, ultimately reducing
the amount of vortexes in
the room. Following the
advice of thermofin GmbH,
the customer ended up using
five thermofin®
units and
built their storage room with
air-guiding veins. According
to Heik, the customer is happy
with the results and has
thankfully not experienced any
occurrences of falling meat.

As thermofin GmbH continues
to expand globally, their plans
for innovative simulation
work continue to grow as
well. " In our future research
plans, we want to design
[heat exchangers with a]
new fin shape, " said Heik.
A change like this requires
that the heat exchanger's
tubes expand in diameter. To
successfully implement this
change, thermofin GmbH first
needs to find the optimal
way to space out these tubes.
" For a new fin geometry, we
would have to simulate it
before we buy the tools to
produce it ourselves, " said
Heik. A modification like this
could help enhance the heat
transfer capabilities of their
heat exchanger designs.
