Modular platform of a chassis of an electric motor vehicle, comprising a cooling module having a tangential turbomachine

A modular platform of an electric motor vehicle chassis,

• the modular platform comprising one or more batteries and an electric powertrain of the electric motor vehicle,
• the modular platform further comprising an upper floor and a lower floor,
• wherein between the upper and lower floor is arranged at least one cooling module configured to have an external air flow passing through it,
• the cooling module comprising at least one heat exchanger, configured to have the external air flow passing through it, and a first collector housing attached to the heat exchanger,
• wherein the first collector housing forms a volute within which a tangential-flow turbomachine extends,
• the first collector housing comprising a first open end facing the heat exchanger and a second open end at the end of its volute,
• wherein the cooling module is arranged such that the second open end of the cooling module faces one or other of the upper or lower floors of the modular platform, and
• wherein the upper or lower floor comprises an opening facing the second open end of the cooling module.
