[0091] Figure 4 A schematic diagram of a thermoelectric module according to a second embodiment of the present invention is shown. Different from the thermoelectric module 200 of the first embodiment, the thermoelectric module 300 of the second embodiment uses a granular support 384 as a support. Furthermore, in the thermoelectric module 300 , the cross-arranged multi-nodal P-type thermoelectric materials 342 and multi-nodal N-type thermoelectric materials 344 are formed by bonding P1 and P2, N1 and N2 thermoelectric materials, respectively.
[0092] Figure 4 Among them, the thermoelectric module 300 includes a first substrate 311 and a second substrate 312 oppositely arranged, a plurality of nodal P-type thermoelectric materials 342 and nodal N-type thermoelectric materials 344, a plurality of first metal electrodes 314 and second metal electrodes 314 An electrode 316 , a plurality of first and second solder alloy layers 321 , 322 , and a particulate support 384 .
