Static Passive Coolers

A Static Passive Coolers (SPC) is a substance with a high heat of fusion which, melting and solidifying at certain temperatures, is capable of storing or releasing large amounts of energy. Also called Phase change material, these are widely used in Telecom enclosures generally for air-conditioner backup. Other usages of these materials are in space applications, waste heat recovery, off peak power utilization, ice storage and conditioning of buildings, heat pump systems, laptop cooling and creating cool suits. The most commonly used SPCs are salt hydrides, fatty acids and esters, and various paraffin (such as octadecane). Recently also ionic At Lambda the creation of Latent heat blends SPC-INTS29 has lead to develop innovative class of low flammability SPC which consist of unique composition of salt hydrates and organic compounds. This combination unites the advantages like stable performance throughout the phase change cycles, high thermal storage capacity with limited super cooling.
