    摘要: A heat exchange method and apparatus, comprising: an air flow channel (90) and a heat sink thermally coupled to the air flow channel (90). Heat is extracted from air (102) flowing along the air flow channel (90) and is stored in the heat sink (92); and the heat sink (92) comprises heat-storage material with a melting point selected relative to the temperature of air (100) intended to be cooled such that the material is initially solid and then melts or starts to melt whilst extracting and storing heat from the air (102) flowing along the air flow channel (90). The heat-storage material may be a heat-storage wax, for example paraffin wax. The heat storage material may be combined with a thermally conducting three-dimensional mesh, for example aluminium foam. The air flow channel (90) may comprise a thermally conducting three-dimensional mesh, for example aluminium foam.

    摘要: A method and apparatus are disclosed for a turboprop-powered medium altitude long endurance (MALE) aircraft, having: a heat exchanger with a heat-storage material, for example a heat-storage wax; and an air recirculation path. The heat exchanger can be arranged to cool air recirculating around the air recirculation path which is arranged to provide cooling to the MALE aircraft, for example to an equipment bay. The heat-storage material may be cooled by ground-based cooling apparatus when the aircraft is on the ground and/or by ram air when the aircraft is in flight. The heat-storage material may have a melting point selected so as to be rendered solid during ground-based cooling and/or ram air cooling, and/or selected so as to undergo melting while cooling the air recirculating around the air recirculation path.
