Finally, obtained heat energy was rapidly moved by steam
towards to header of the heat pipe that is colder than other sides.
Because of the construction of the heat pipe there is no need to
extra heat spreader sheet that is located on head of heat pipe in
designed system. The header of the pipe is constructed to fit the
dimensions of TE module sizes. In general, Thermo electrical
generator contains a number of semiconductor p and n type
element that are thermally in parallel but electrically in series. In
the system, TEG1-12611-6.0 type module was used with the
dimensions of 56 mm length, 56 mm width and 4 mm height, that
is composed 126 numbers of junctions. Elements in the TE module
are made from Bi2Te3. The details of the used TE module were
given in Table 1 and Fig. 3 [23].
