A vehicle heat transfer system includes a flow through heat exchanger, a surface heat exchanger, at least a first vehicle component, and a controller that is operable to selectively transfer heat to or from the first vehicle component with either or both of the flow through heat exchanger and the surface heat exchanger based on one or more operating conditions. In a further aspect, a vehicle heat transfer system includes, a vehicle component positioned on a vehicle that is heated or cooled by a fluid, and a surface heat exchanger positioned on the vehicle, the surface heat exchanger having an inlet that receives the fluid used to heat or cool the vehicle component, an outlet that returns the fluid to heat or cool the vehicle component, and a closed fluid path extending between the inlet and the outlet.

A grille assembly for a vehicle is disclosed and includes a forward frame portion, an aft frame portion, and a plurality of spring portions coupling the forward frame portion to the aft frame portion such that the forward frame is movable relative to the aft frame portion. A front end assembly for a vehicle is also disclosed that includes a bolster assembly and an active grille shutter system supported relative to the bolster assembly. The disclosed active grille shutter system includes a plurality of spring portions coupling forward and aft frame portions such that the forward frame is movable relative to the aft frame. Vanes are supported by at least one of the forward and aft frame portions and are rotatable for controlling airflow.

The present disclosure relates to an active air flap apparatus for a vehicle coupled to an air inlet of a grill to cool the inside of an engine room when a vehicle travels, and the active air flap apparatus for a vehicle includes a frame coupled to a rear surface of the grill in which the air inlet is formed, a plurality of flap portions coupled to an inside of the frame to open or close the air inlet and arranged in a vertical direction of the frame, an actuator coupled to an outside of the frame to generate power, a gear unit operated by the power generated from the actuator, and a connection unit connecting the flap portions and the gear unit to each other to operate the flap portions according to the operation of the gear unit.

An air flap for an air flap assembly for a vehicle front is provided. The air flap has a front face and a lateral face having a slotted guide system. The air flap blocks an air inlet in the vehicle front through the front face in a closed position and opens the air inlet in an open position. The air flap is rotatable from the closed position into the open position by a rotary movement about an axis of rotation by way of a driver of an actuator, which driver can be guided in the slotted guide system. The slotted guide system located on the lateral face of the air flap has a tapered portion, so that the slotted guide system and the driver have substantially no play in relation to one another in the region of the tapered portion.

An active air flap system for a vehicle is provided. The system includes an exterior surface having at least one or more openings, a housing provided on a rear side of the exterior surface, a flap rotatably mounted on the housing, and a driving section rotating the flap to open and close the openings. The driving section has a dual link structure including a first link moving in a vertical direction and a second link connecting the first link and a flap linkage forming an operating shaft of the flap, so that when the flap is operated, the rotation angle of the flap is increased, and interference between the flap and the bumper is prevented from occurring.

A mounting structure of two resin components includes a primary component including an insertion piece extendedly provided from a base portion, and an engagement recessed portion formed in the insertion piece; and a secondary component formed capable of being mounted to the primary component and including an insertion portion configured to guide the insertion piece formed at the base portion, an engagement protruding portion formed in the insertion portion and configured to fit into the engagement recessed portion of the insertion piece, and a restriction wall configured to cover a root side of the insertion piece inserted into the insertion portion, and in a top plan view, a width of the restriction wall being gradually decreased toward a direction separating from a side where the primary component is mounted.

An active side vent system for a vehicle can include a housing disposed in a side vent opening defined by a recessed surface in a rear portion of a front fender of the vehicle, a set of louvers disposed in the housing and configured to pivot such that (i) in an open position, none of the set of louvers extends beyond an outer surface of the front fender and (ii) in a closed position, the set of louvers are substantially flush with the recessed surface of the front fender, and an actuator configured to control the pivoting of the set of louvers.

A shutter system for controlling a flow of an incident airstream through a grille opening in a vehicle includes a track arranged transverse to the airstream. The shutter system also includes a plurality of louvers configured to shift along the track and be guided thereby. The shutter system additionally includes a mechanism configured to select a position for the shutter system between and inclusive of fully-opened and fully-closed to regulate the flow of the incident airstream through the grille opening by shifting the plurality of louvers along the track. Each of the plurality of louvers is arranged along a plane transverse to the incident airstream and remains therein as the position of the shutter system is selected between and inclusive of fully-opened and fully-closed.

Methods and systems are provided for estimating a cooling demand of a vehicle powertrain component and selecting a mode of operation of a vehicle cooling system based on the estimated cooling demands of the vehicle powertrain component and the energy usage of the cooling system components. Based on the selected operating mode, each of a radiator fan speed, a coolant system pump output, a vehicle grille shutter opening, and an opening of vents coupled to a powertrain component insulating enclosure may be concurrently adjusted to minimize the cooling parasitic losses while satisfying the cooling requirements of the vehicle.
