Cooling conduit

[0019]FIGS. 1 and 2 illustrate diagrammatically, in a top view and a perspective view respectively, an exemplary air conduit 1 according to the invention for cooling a battery pack. It is made of a material with a high thermal conductivity, a metal alloy for example, or else a plastic material. It is intended to be arranged in the battery pack (not shown on the figures), which may be made from a plastic material. The air conduit 1 comprises a mouth 11 for the entry of a fresh air flow FE. The inlet opening of the mouth 11 is intended to be housed in an opening made in the battery pack, in order to allow the entry of air into the pack via the mouth 11. The air conduit 1 also comprises a mouth 12 for the exit of a heated air flow FS. The outlet opening of the mouth 12 is intended to be housed in another opening made in the battery pack, in order to allow the exit of air from the pack via the mouth 12. The air conduit 1 finally comprises channels 13, 14, 15 and 16 which connect the inlet
