Air to Air Heat Exchangers are suitable in electronics cooling for increasingly miniaturized components within enclosures, or for demanding applications like telecommunications or military/aerospace where weather can be a factor. The Exchangers can either be forced convective or natural convective type of heat sink, to transfer the heat within the electronic enclosures to the outside ambient air for rejection. The Exchangers are manufactured using quality grade material that ensures good quality. The Air to Air Heat Exchangers are durable that ensures long lasting life.
