Patent ID: 8664509

Claim:
A thermoelectric apparatus, comprising: a first assembly, comprising: a first substrate and a second substrate opposite to each other, wherein the first substrate has at least a first through hole; and a plurality of first thermoelectric material sets disposed between the first substrate and the second substrate, wherein each first thermoelectric material set has a p-type thermoelectric element and an n-type thermoelectric element electrically connected to each other, and the first thermoelectric material sets evolve heat at a first side connecting to the first substrate and absorb heat at a second side connecting to the second substrate; a second assembly stacked above the first assembly, comprising: a third substrate and a fourth substrate opposite to each other, wherein the fourth substrate has at least a second through hole, and the fourth substrate is located between the third substrate and the first substrate; and a plurality of second thermoelectric material sets disposed between the third substrate and the fourth substrate, wherein each second thermoelectric material set has a p-type thermoelectric element and an n-type thermoelectric element electrically connected to each other, and the second thermoelectric material sets evolve heat at a third side connecting to the third substrate and absorb heat at a fourth side connecting to the fourth substrate; at least a first heat conductor penetrating the first through hole, wherein two ends of the first heat conductor physically connect the second substrate and the fourth substrate respectively, such that a first end of the first heat conductor is in direct physical contact with the second substrate and a second end of the first heat conductor is in direct physical contact with the fourth substrate; and at least a second heat conductor penetrating the second through hole, wherein two ends of the second heat conductor physically connect the third substrate and the first substrate respectively, such that a third end of the second heat conductor is in direct physical contact with the first substrate and a fourth end of the second heat conductor is in direct physical contact with the third substrate.
