Abstract
Cooling module including a housing configured to accept a tangential-flow turbomachine having a turbine with at least one stage of blades forming a hollow cylinder, the turbomachine also having a motor configured to drive the rotation of the turbine, the motor including a stator and a rotor mounted with the ability to rotate about the stator. The stator of the motor is secured to the housing in such a way that the blades of the turbine are arranged circumferentially around the rotor of the motor, and in that the at least one stage of blades of the turbine is mechanically connected to the rotor of the motor so as to be driven in rotation thereby.
Claims11
A heating, ventilation and/or air-conditioning device for a motor vehicle, said device having a vertical dimension defined along a vertical direction, said heating, ventilation and/or air-conditioning device comprising a housing and, inside the housing, a first heat exchanger and a unit for generating an air flow, said first exchanger extending in a direction close to said vertical direction to define a vertical dimension of the first heat exchanger and also extending in a transverse direction, along a transverse axis, perpendicular to the vertical direction, said unit for generating the air flow including a wheel configured to rotate about an axis of rotation, oriented substantially in said transverse direction, and to generate the air flow tangentially in the direction of said first exchanger, said wheel being arranged so as to remain within the vertical dimension of said first exchanger when viewed perpendicularly to the vertical direction, said housing being configured to extend on either side of a wall separating an engine compartment from a passenger compartment of the motor vehicle, a first part of the housing accommodating the unit for generating the air flow being intended to be situated on the engine compartment side and a second part of the housing accommodating the first exchanger being intended to be situated on the passenger compartment side.
A vehicle comprising an engine compartment, a passenger compartment and a separation wall between said engine compartment and said passenger compartment, said vehicle further comprising a heating, ventilation and/or air-conditioning device for a motor vehicle, said device having a vertical dimension defined along a vertical direction, said heating, ventilation and/or air-conditioning device including a housing and, inside the housing, a first heat exchanger and a unit for generating an air flow, said first exchanger extending in a direction close to said vertical direction to define a vertical dimension of the first heat exchanger and also extending in a transverse direction, along a transverse axis, perpendicular to the vertical direction, said unit for generating the air flow including a blower wheel configured to rotate about an axis of rotation, oriented substantially in said transverse direction, and to generate the air flow tangentially in the direction of said first exchanger, said blower wheel being arranged so as to remain within the vertical dimension of said first exchanger when viewed perpendicularly to the vertical direction, said housing being configured to extend on either side of a wall separating an engine compartment from a passenger compartment of the motor vehicle, a first part of the housing accommodating the unit for generating the air flow being intended to be situated on the engine compartment side and a second part of the housing accommodating the first exchanger being intended to be situated on the passenger compartment side.
