Abstract
The invention relates to an electronic device operating in difficult environments. The electronic device comprises at least one 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, characterized in that it also comprises a cover delimiting a channel in which a coolant circulates to ensure convection, the cover being joined to the heat sink and the printed circuit board, and in that the channel prevents the coolant from coming into contact with the electronic components.
Claims14
An electronic device comprising an electronic gear module configured to house one or more plug-in electronic subassemblies, each electronic subassembly comprising:
- 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,
- the subassembly also comprising:
- a cover joined to the heat sink and the printed circuit board, delimiting a channel between the second side of the heat sink and the cover, for a coolant to circulate to ensure convection, deformable seals ensuring the seal-tightness of the channel,
- said channel preventing the coolant from coming into contact with the electronic components.
