Temperature rises in any electrical or electronic enclosure without a climate control system. This happens because of::

. Components electrical loss.
. External heat transmission.
. Solar Radiation.

The final temperature in an uncontrolled enclosure could be higher than the maximum recommended values of the internal components, thus affecting its performance and even causing irreversible damage.

There are different climate control solutions to keep the enclosure internal temperature within the range recommended by the components' manufacturers.
