Ventilation-cooled avionics module

An avionics module comprising:

• an electronic circuit board comprising a first and a second face, a case in which said electronic circuit board is positioned, the case comprising a first facing wall and a second facing wall and at least one inlet orifice and at least one outlet orifice for the passage of cooling air,
• a first corridor for the circulation of cooling air, the first corridor being formed between the first face of the electronic circuit board and the first facing wall of the case, and
• a second corridor for the circulation of cooling air, the second corridor being formed between the second face of the electronic circuit board and the second facing wall of the case,
• wherein said avionics module comprises at least one baffle fixed to the electronic circuit board for controlling the distribution of cooling air between the first and the second corridors, and;
• the electronic circuit board comprises at least one opening for the passage of cooling air and the baffle comprises an inclined wall for guiding cooling air toward said opening
