Abstract: The thermal generator (1) which comprises at least one thermal module (10) constituted from many thermal elements (40), stacked and arranged in order to delimit channels therebetween for circulation of heat transfer fluid. These channels are divided into hot channels, in which the heat transfer fluid of the hot circuit flows, and cold channels, in which the heat transfer fluid of the cold circuit flows. The hot and cold channels are alternated between the thermal elements (40) and the thermal elements have fluid inlet and outlet orifices which communicate with one another so as to distribute the flow of heat transfer fluid of each hot and cold collector circuit, respectively, in the corresponding hot and cold channels.
