Cooling module an electric or hybrid motor vehicle, comprising a tangential-flow turbomachine
Cooling module ( 22 ) for an electric or hybrid motor vehicle ( 10 ), through which cooling module ( 22 ) an air flow (F) is intended to pass, comprising: —a set of heat exchangers ( 23 ) comprising: —a first heat exchanger ( 24 ) configured to be a condenser connected within an air conditioning circuit (A), and —a second heat exchanger ( 26 ) configured to be a low-temperature radiator connected within a thermal management circuit (B), —a tangential-flow turbomachine ( 30 ) configured so as to generate the air flow (F), the set of heat exchangers ( 23 ) further comprising a third heat exchanger ( 28 ) configured to be a sub-cooler connected within the air conditioning circuit (A), the third heat exchanger ( 28 ) being arranged within the set of heat exchangers ( 23 ) furthest upstream in the direction of the air flow (F).
1. A cooling module for an electric or hybrid motor vehicle, said cooling module being designed to have a flow of air passing through it, and comprising:
a set of heat exchangers comprising:
a first heat exchanger configured to be a condenser connected within an air-conditioning circuit, and
a second heat exchanger configured to be a low-temperature radiator connected within a heat control circuit; and
a tangential-flow turbomachine configured such as to generate the flow of air,
wherein the set of heat exchangers also comprises a third heat exchanger which is configured to be a sub-cooler connected within the air-conditioning circuit, said third heat exchanger being positioned within the set of heat exchangers which is furthest upstream in the direction of the flow of air,
wherein the second heat exchanger is positioned upstream from the first heat exchanger in the flow of air within the set of heat exchangers, and
wherein, within the set of heat exchangers, the second heat exchanger and the third heat exchanger are positioned on a same plane and are the furthest upstream in the direction of the flow of air.
