A data acquisition module (1) includes an interconnection board (15) with several electronic components (3, 18) mounted on at least one side of said board. A protective cover (16) mounted opposite said side covers the electronic components (3, 18).In order to cool notably the module's analog-to-digital converters, a piston 41 connected to the protective cover (16) is pressed by a spring (43) against the upper side of at least one electronic component (3) so as to establish a thermal bridge between said electronic component and said protective cover.The piston is mounted in a piston carrier fastened on the cover (16). The diameter of the portion (410) of the piston (41) that is in contact with the electronic component (3) to be cooled is smaller than the diameter of the portion (411) of the piston that is in contact with the piston carrier (40).
