THERMOELECTRIC COOLING MODULE Russian patent published in 1999 - IPC

FIELD: cooling appliances. SUBSTANCE: module has n thermoelectric batteries arranged in tandem and n+1 heat storages made of heat-conducting material and placed between batteries and at heat-transfer and heat- absorbing sides of module. Heat insulation around batteries and heat storages has two layers; external layer is hard and internal one provides for axial displacement of module components. Module accommodates mechanism with flexible members that function to permanently hold down thermal batteries and heat storages in axial direction. Module may also accommodate one or more composite heat storages coupled through their cylindrical heat-transfer surfaces and covered with heat-transfer compound. Flexible members are fitted between end surfaces of composite parts of heat storage. Batteries and heat storages may be joined together along axis by means of screw. Internal insulation may be made of wax or parlon. External heat storages may be made in the form of removable heat- transfer apparatuses. EFFECT: improved design. 6 cl, 4 dwg
