Title:
Method and device for forming thermobranches containing a foam structure
Document Type and Number:
WIPO Patent Application WO2000073712
Kind Code:
A3
Abstract:
The invention relates to novel thermobranches (7) containing a foam structure and to novel assemblies resulting from the same in thermoelectrical strips (28) which have a foamed boundary layer, in pressure-contacted thermoelectrical strips (32) and to conventional types of connections which involve thermobranches (11) having a foam structure throughout, assembled thermobranches (12) and integrated active-passive thermobranches (14). Said assemblies and connections enable the optimised use of the thermoelectric potential of already conventional semiconductor materials and of semiconductor materials which have hitherto not been able to be used as thermoelectric materials (3) and provide a high degree of thermoelectric efficiency. The entire content of the foam structure is provided with homogenous or differentiated portions of an active phase and is capable of minimising the waste thermal currents (8) which reduce the degree of efficiency. The invention also relates to accompanying and replicating methods, effective in this field, for optimising the thermoelectric active phases (30) in closed pore structures consisting of non-metallic foams (31) or a sinter structure which are in the process of being formed or hardened. The invention can be used both for generating thermoelectricity and in Peltier technology.
