Protective cover of the piece (s) has elements (s) of the air pipe a suction effect, and a casing associated

摘要

A cap (cp) is intended to be protected at least a part (cl) adapted to radiate heat, and comprises a main wall (pp) with aeration means (mai) and intended, once installed in a system, to be placed opposite the part (cl) and in a vertical direction or in a direction inclined. These ventilation means (mai) comprise at least one element of the air pipe projecting above the general level of the external face (fe) of the main wall (pp) with a so-called lower end (e1) provided with an air inlet (ea) communicating with an internal zone (z1) located behind the inner face (f) of the main wall (pp), opposite the outer face (fe), and a so-called upper end (e2) provided with an air outlet (its) communicating with the inner zone (z1) and intended, once the cap (cp) is installed, to be located at a level higher than that of the air inlet (ea) so as to produce an effect of suction of air which is adapted to promote the evacuation of the heat radiated by thermal convection.
