| Outline of Final Research Achievements |
Normally two types of materials are cut in cuboid, welded in series as Pai-type shape to form a thermoelectric module. In order to give a temperature difference between two flat terminals in the module, a duble spiral structure may solve this problem considering smooth flow of two fluids. To realize the spiral module, the TE cuboid should be tilted with orthorhombic symmetry, and they may form a tilted module. Evaluating numerically the temperature dependency of material properties and the radiation effects on the module using the cylindrical axis, the elongated tilted module can save the mechanical loss and give the maximum output.
