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.
