Air-to-air heat exchanger

The air-to-air heat exchanger from Advance Cooling Systems, Mumbai, is used to transfer heat from inside the electronic enclosure to the outside atmosphere. These heat exchangers are used in situations where the ambient air is not excessively hot or moisture laden, and where the electronic controls operate at a temperature differential slightly above the ambient temperature. This heat exchanger attaches directly to the panel and circulates two totally separate air streams, sealed from each other, in two sets of channels formed from thin gauge aluminium. The internal stream picks up the component heat from top and travels downwards through one set of channels. The external stream travels upwards through the other set and cools the internal stream without mixing, through the thin aluminium wall of the channels. The rate of heat transfer can be as high as 100 watts/Kelvin. Heat is transferred from the interior of the panel at a high rate, without introduction of dust, moisture or fume laden outside air. The channels form a removable module, which can be easily cleaned by washing periodically.
