The invention relates to a device for converting thermal energy to electrical energy, comprising at least one thermoelectric module () which has an outer surface having a hot side () for contacting a heat source and having a cold side () for contacting a heat sink, wherein the hot side of the thermoelectric module is thermally conductively connected to a heat source, in particular an exhaust channel () of a combustion engine. The device further comprises a cooling channel () through which a cooling fluid can flow and which is thermally conductively connected to the cold side of the thermoelectric module. The cooling channel has at least one opening to the cold side of the thermoelectric module and is sealed in a fluid-tight manner around the opening with respect to the hot side of the thermoelectric module.
