Thermoelectric device

A thermoelectric device comprising:

• a fluid flow part including one surface and the other surface spaced apart from the one surface in a first direction;
• a first thermoelectric element disposed on the one surface of the fluid flow part;
• a second thermoelectric element disposed on the other surface of the fluid flow part,
• a first guide member disposed on a side surface of the first thermoelectric element on the one surface of the fluid flow part;
• and
• a second guide member disposed on a side surface of the second thermoelectric element on the other surface of the fluid flow part, wherein
• a first through hole passing through the fluid flow part from the one surface to the other surface is disposed in the fluid flow part,
• a wire electrically connected to the first thermoelectric element passes through the first through hole and is electrically connected to the second thermoelectric element,
• a second through hole overlapping the first through hole in the first direction is disposed in the first guide member,
• a plurality of holes passing through the fluid flow part from the one surface to the other surface and not overlapping the first thermoelectric element and the second thermoelectric element in the first direction are disposed in the fluid flow part,
• at least one first coupling hole is disposed in the first guide member,
• at least one second coupling hole is disposed in the second guide member,
• the first guide member and the fluid flow part are fixed by coupling members disposed in the at least one first coupling hole and some of the plurality of holes, and
• the second guide member and the fluid flow part are fixed by coupling members disposed in the at least one second coupling hole and some of the other holes of the plurality of holes.
