Thermoelectric module

A thermoelectric module comprising a plurality of thermoelectric elements electrically connected via a plurality of conductor bridges, wherein:

• a respective conductor bridge of the plurality of conductor bridges, on at least one of a hot side and a cold side of the thermoelectric module, is in contact with an electrically insulating, thermally conductive duct body through which a fluid is flowable;
• the duct body, on a side facing the plurality of conductor bridges, has a plurality of recesses in which, respectively, one of the plurality of conductor bridges is arranged;
• the plurality of thermoelectric elements are arranged in a joint thermally insulating filling body;
• the plurality of conductor bridges are arranged flush with the filling body on at least one of the hot side and the cold side;
• the duct body has a duct base body and a duct cover, the duct cover closing the duct base body and defining a fluid-tight duct therewith;
• and
• the duct base body, on a side facing away from the plurality of conductor bridges, includes a plurality of heat transfer elements protruding into the duct body around which the fluid is flowable.
