An aircraft engine air inlet lip takes an annular form about a longitudinal axis and delimits an air inlet stream, and includes: a wall having a U-shaped profile having an outer face oriented towards outside of the air inlet lip and an inner face oriented towards interior of the air inlet lip, an inner wall extending inside the wall between two zones of the inner face, so as to close an inner chamber delimited between the wall and the inner wall and filled with a gas, the inner wall having an upstream face oriented towards and a downstream face oriented away from the inner chamber, a fan configured to move the gas contained in the inner chamber, and at least one pipeline fixed to the upstream face and extending all around the air inlet lip and configured to be fed with a heat transfer fluid heated by a heat source.

A method for distribution of cooling air for cooling an electrical equipment item installed in an avionic bay. Cooling air is drawn from an air vein, then passes into a first pressure zone in fluidic communication with the air vein and then into a second pressure zone in fluidic communication with both the first pressure zone and the electrical equipment. The second pressure zone extends beneath a largest dimension (e.g., length) of electronic boards of the electrical equipment to be cooled.

An electronic board for avionics equipment, the board comprising a printed circuit, a reinforcing surround and board retention means. In order to improve the vibration resistance of the board, the board further comprises vibration damping means interposed between the reinforcing surround and the retention means.

This invention relates to a fluid-cooled electronic equipment item, an avionic rack to receive such an equipment item and an aircraft equipped with such racks. The electronic equipment items are connected to the avionic rack on the one hand electrically (C-C) and on the other hand fluidically (--) to a system of pipes () on at least one cold source for a cooling fluid (). A heat-dissipating electronic board () is equipped with a dissipated-heat collector plate (-), in which fluid circulation channels are implemented, connected via quick-disconnect fluidic couplings () to quick-disconnect fluidic couplings of the system of pipes. These devices allow the equipment to be removed from or inserted into the rack (-EE) or the electronic board () to be removed from or inserted into the electrical equipment (-).

An avionic bay with a device for filtering cooling air for aircraft electrical equipment. The device includes at least two filtration grilles provided with apertures and which are disposed successively one behind the other in order to filter the air drawn from a cooling air vein before distributing it to an aircraft electrical equipment item. The apertures of the second grille are offset transversely in relation to the apertures of the first grille.
