Abstract:
1. An electronic device comprising: an electronic gear module configured to house one or more plug-in electronic subassemblies, each electronic subassembly comprising a joined assembly which includes a printed circuit board supporting heat-dissipating electronic components, a heat sink, a first side of which is in contact with electronic components on a first side of the printed circuit board and a second side of which is designed to evacuate heat by convection, and a cover applied against the second side of the heat sink with deformable seals in between for maintaining a free space between said second side of the heat sink and the cover, said delimited free space of the joined assembly between the second side of the heat sink and the cover forming a channel for a coolant to circulate to ensure convection, wherein the deformable seals ensure a seal-tightness of the channel, and said channel prevents the coolant from coming into contact with the electronic components.
