MODULAR ELECTRONIC DEVICE OPERATING IN DIFFICULT ENVIRONMENTS

摘要

The invention concerns an electronic device operating in difficult environments. The electronic device comprises at least one printed circuit board (1) supporting electronic heat-dissipating components, a radiator (5) having a first surface (51) in contact with the electronic components of a first surface (111) of the printed circuit board (1) and having a second surface (52) configured to evacuate heat by convection. The invention is characterized in that it further comprises a cover (10) delimiting a channel (4) wherein flows a coolant (20) providing convection, the cover (10) being secured to the radiator (5) and to the printed circuit board (1), and in that the channel (4) prevents the coolant (20) from coming into contact with the electronic components.
