Abstract

This housing comprises rackable electronic equipment modules (2) housed in a bay. A module (2) has both internal (12, 13) and external (45) thermal radiators cooled by natural and forced ventilation. The internal thermal radiators (12, 13) are placed in thermal contact with the hot spots of the electronic equipment placed in the module (2) via hear collectors (40, 41) connected by heat pipe (42, 43) to the external thermal radiators (45) arranged outside on the edge (44) of the module (2). The internal thermal radiators (12, 13) are sized to be sufficient to cool the electric equipment when the forced ventilation is functioning normally. The external thermal radiators (45) are sized to complement the cooling provided by the internal radiators (12, 13) should the forced ventilation be lost.

Dependent claims

An electronic equipment housing adapted to be cooled by natural air ventilation and by forced air ventilation owing to ventilation holes of walls of the housing, using pulsed air, said housing comprising:

at least one internal thermal radiator adapted to be cooled by natural and forced air ventilation and in thermal contact with one or more hot spots of an electric equipment located inside the housing;
at least one heat collector for said at least one internal thermal radiator in thermal contact with said one or more hot spots;
at least one external thermal radiator;
at least one thermal conductor connected to said at least one heat collector, passing through one of the walls of the housing, and leading to the corresponding external thermal radiator;
and
removable modules arranged side by side in a direction parallel to a back wall of the housing,
wherein the at least one external thermal radiator is placed in one or more corresponding chimneys with natural and forced air ventilation and fixed, outside of the housing, to the wall through which the at least one thermal conductor passes and which defines front edges of the modules.
