A cooling system for a vehicle including an air duct having an inlet funnel configured to connect to a vehicle grill, a heat-exchanger seat defining an outlet window, and an upper panel extending from the inlet funnel over top of the outlet window. The upper panel defines an intake. At least one heat exchanger is received on the heat-exchanger seat. A cooling fan assembly is disposed under the at least one heat exchanger and includes a shroud and a fan.

Vehicle cooling system

A cooling fan module may include a fan assembly and a shroud. The fan assembly including a number of fan blades and the shroud including a first sidewall and a first ring. The first sidewall defining an opening and the first ring extending in an axial direction from the first sidewall. The first ring including an inner periphery provided with a number of first serrations, each serration of the number of first serrations extending in a radial direction. The radial direction is substantially orthogonal to the axial direction.

Cooling fan module

The cooling pack assembly includes, a shroud, a fan, a first heat exchanger, and a second heat exchanger. The shroud has a plurality of sidewalls including a main sidewall. The shroud further defines an aperture. The fan is disposed within the aperture. The fan is configured to rotate about a rotational axis. The rotational axis is normal to a plane defined by the main sidewall. The first heat exchanger is disposed on at least one of the plurality of sidewalls. The first heat exchanger has a first cross-sectional area substantially parallel to the plane. The second heat exchanger is disposed on at least one the plurality of sidewalls. The second heat exchanger has a second cross-sectional area substantially parallel to the plane. The second cross-sectional area is less than the first cross-sectional area, and the first heat exchanger is disposed between the fan and the second heat exchanger.

Cooling pack assembly

The cooling fan module may include a fan assembly and a fan shroud. The fan shroud of the cooling fan module may include a first sidewall that may extend in a radial direction and define an opening. The fan assembly may include a hub disposed within the opening, a blade extending from the hub to a distal end that may include a first side and a second side converging to form a first leading edge with respect to the rotational direction. The fan assembly may include a winglet that may include a first fin, extending in the axial direction from the distal end of the blade and a second fin extending in the radial direction.

The fan assembly provided with a fan ring, including a first leg and a second leg, may be arranged with a shroud that may include a first sidewall, a second sidewall, a third sidewall, a first ring, a second ring, and a third ring. An air passage may be formed between a distal end of the first leg and the third ring, the second ring and the first leg, the second leg and the second sidewall, and a distal end of the first leg and the first ring. The air passage may be configured to improve acoustic performance and air flow efficiency.

Integrated downstream funnel

A cooling fan module is provided. The cooling fan module may include a frame, a fan assembly, a number of guide vanes, and a cylindrical deflector. The frame may include a sidewall that defines an opening and an outer periphery. The fan assembly may be disposed within the opening and include fan blades extending from a hub and terminating at a fan ring. The fan ring may have a curved profile. The number of guide vanes may be disposed radially around the opening. The cylindrical deflector may extend axially from the sidewall and radially surround the number of guide vanes. The cylindrical deflector may be disposed radially between the number of guide vanes and the outer periphery.

The invention relates to a fan and a fan module, wherein the fan comprises: a fan hub which comprises a fan rotation axis to rotate in a predetermined direction, a plurality of fan blades comprising a lower end and an upper end, wherein each fan blade is attached with its lower end to the fan hub and extends radially outwardly from the fan hub, wherein each fan blade comprises a lower back sweep portion and an upper forward sweep portion, wherein a maximum ratio r/R of the lower back sweep portion is at least 0.90, wherein r is the local radius of a point of the fan blade edge, and R is the radius of the upper end of the fan blade.

Fan and fan module

A cooling fan module includes a frame, and a fan impeller having a plurality of fan impeller blades is located in an opening of the frame. The fan impeller blades are connected to a base portion of an outer fan ring. A lip portion of the outer fan ring extends from the base portion radially outward, and a leading end of the lip portion is turned in direction to the downstream side of the frame. A recirculating flow guiding device includes a plurality of guide vanes located on an upstream side of the frame and around the opening of the frame. An air gap is provided between the outer fan ring and the frame. A recirculating flow travels from downstream side of the cooling fan module through the air gap, and is turned by the leading end of the lip portion into the recirculating flow guiding device.

Cooling fan module and system

The present invention relates to a centrifugal fan assembly and a HVAC-system, comprising a housing, a blower wheel comprising a plurality of fan blades, the blower wheel being rotatably mounted in the housing and constructed to generate an airflow flowing axially into the blower wheel and radially out from the blower wheel, a guiding vane device including a plurality of guiding vanes, the guiding vane device being coupled to the blower wheel and configured to guide the airflow into the blower wheel.

Centrifugal fan assembly

A cooling fan for a vehicle. Many engine compartments of motor vehicles are small in size, and contain numerous components. Electric cooling fans are used to draw air through a radiator. Given the cramped conditions within the engine compartment, the exhaust of the fan cannot be directed into open air, but must impinge on one or more of the components within the compartment. This situation reduces velocity in the exhaust, and also reduces efficiency of the fan. The invention provides a collection of generally co-axial stators which divert the exhaust around the components, while retaining much of the velocity of the exhaust.

Vehicle cooling fan

A cooling fan for an engine in a vehicle. Ordinarily, a fan rotates within a shroud, which surrounds the fan. Leakage can occur between the tips of the fan blades and the shroud, wherein fan exhaust moves forward, and then passes through the fan again. The invention reduces leakage by placing a surface downstream of the fan. The surface employs the Coanda Effect, to urge fan exhaust to continue in the downstream direction, and not move forward as leakage air.

Cooling fan using Coanda effect to reduce recirculation

An electrically powered axial-flow fan has a hub to house the motor and support the fan blades. Small blades or vanes on the inside of the hub function as a radial-flow blower to draw cooling air through cooling ports on the electric motor housing. The vanes inside the hub cooperate with a flange surrounding the motor to form a low pressure chamber under the hub to improve cooling flow through the motor. This motor cooling air flow is then ejected into the exhaust stream of the axial-flow fan.

Fan hub assembly for effective motor cooling

A cooling fan having a circumferential ring. In ordinary fans of this type, deformation of fan blades causes the ring to buckle inward at locations between the blades. In one form of the invention, mass is added to the ring between the blades to counteract the buckling.
