Air-air exchanger
Natural convection causes the temperature
to drop inside the enclosure. Simple
solutions for this case include installing
grilles (without filter) or lifting the top.
Fans with filters are designed to evacuate
a large amount of heat economically.
Air-air exchangers are equipped with
an aluminium exchange cassette which
separates the internal and external air
circuits and prevents the entry of dust.
When should it be used? This solution can only be used when the
power to be dissipated is low, in an
environment with small amounts of dust.
When larger amounts of heat need to be
evacuated in a polluted environment.
The air-air exchangers are used in highly
polluted environments or when it is
necessary to evacuate large amounts of
heat while guaranteeing the independence
of the internal and external air circuits.
It is important to have a difference of
temperature of at least 10°C.
