Its
high thermal conductivity, coupled with comparatively low cost and ease of
working, makes aluminum the metal of preference wherever heating or cooling is
required. By the use of foil gauges the maximum surface area and minimum metal
can be used to transfer heat. Aluminium foil allows a high level of energy
efficiency within the smallest possible space. The metal’s low weight also
saves the amount of structure needed to house or to carry aluminum-based heat
exchange units.
Such
considerations are important where, for example, the heat exchanger is used in
aircraft, cars and trucks. Weight and space saved in all forms of transport
mean ‘knock-on’ efficiencies in fuel and vehicle capacity.
In
homes, offices and factory buildings compact heating and air conditioning units
allow the architect or designer great flexibility in the location and format of
equipment. BT offers a high level of corrosion resistance, so that no
protective coating or finish is usually necessary and maintenance is minimal.
Due
to aluminium’s recyclability the used metal is available for re-use after the
heat exchange equipment has completed its useful lifespan. Both static and
mobile heating and cooling installations incorporate aluminum foil, making a
significant contribution to efficiency and sustainability.
