A cooling assembly for a motor vehicle, the cooling assembly having a primary heat exchanger comprising a pair of primary collector boxes, the primary collector boxes with primary header plates, the primary header plates being of essentially rectangular shape; a plurality of primary tubes stacked between the primary header plates; a secondary heat exchanger comprising a pair of secondary collector boxes with secondary header plates being of essentially rectangular shape; a plurality of secondary tubes stacked between the secondary collector boxes. The primary heat exchanger and the secondary heat exchanger are arranged in parallel, perpendicularly to each other so that the secondary header plates of the secondary heat exchanger at least partially overlap the stack of the primary tubes of the primary heat exchanger.

A vehicle includes a pump, an evaporator, and an expander in sequential fluid communication in a closed loop containing a condenser configured to transfer heat between a working fluid and ambient air. The vehicle has a generator driven by the expander. The evaporator is configured to transfer heat from at least one of an engine coolant, a battery coolant, an engine lubricant, a transmission lubricant, an exhaust gas in an exhaust system, and an exhaust gas in an exhaust gas recirculation (EGR) system to the working fluid.

A heat exchanger includes a core including a plurality of tubes and a plurality of air passages, an air inlet portion in fluid communication with the air passages, and an air outlet portion in fluid communication with the air passages. The tubes and the air passages are alternately arranged to be parallel with each other. The core extends along a core plane defined by the tubes and the air passages. The core is disposed such that the core plane is parallel to a vehicle horizontal plane. Outside air flows through the air passages in a first direction. Thermal medium flows through the tubes in a second direction opposite to the first direction. The air inlet portion is open at a front side of the vehicle or a lateral side of the vehicle. The air outlet portion is open at the front side of the vehicle or the lateral side of the vehicle.

An air duct for a vehicle may include a front duct formed forward to take in an exterior air in front of the vehicle, a rear duct formed relatively rearward from the front duct such that the exterior air flowing via the front duct passes therein, and a duct outlet flowing out the exterior air flowed via the rear duct, wherein the air duct may be disposed at both sides of an exterior air intake port taking in the exterior air in front of the vehicle into an engine compartment, and wherein both front ducts may be formed to be bent such that extension lines thereof form a streamlined shape in front of the vehicle.

A passive cooling system includes a fan configured to generate an air flow path for a radiator, the air flow path extending from the fan to the radiator and a cooling pipe extended between a turbocharger and an intake manifold, the cooling path positioned in the air flow path between the fan and the radiator.

The invention relates to a cooling module for a motor vehicle, including at least one heat exchanger, at least one tangential turbomachine, a housing having a first suction opening and an exhaust opening between which flows a first air stream passing through the at least one heat exchanger and at least one electric motor for controlling the rotation of the at least one tangential-flow turbomachine, the electric motor being arranged on the outer wall of the housing, the electric motor including at least one air inlet and one air outlet. The housing includes a second suction opening, the air outlet of the motor being in fluid connection with the second suction opening so as to allow a second air stream to flow.

A method for operating a vehicle cooling system includes generating, via a main cooling unit, a main cooling air flow passing through a first heat exchanger arrangement in a main cooling path; generating, via a secondary cooling unit, located upstream in the main cooling path, a secondary cooling air flow passing through a second heat exchanger arrangement in a secondary cooling path branching off upstream in the main cooling path; in a first operating mode, operating, via a control unit, both the main cooling unit and the secondary cooling unit in order to generate mutually independent cooling air flows; and, in a second operating mode, operating, via the control unit, the main cooling unit and setting the secondary cooling unit to one of a stationary and an idle operating state.
