A shroud is coupled to a radially outer end of the plurality of fan blades. The shroud includes an axially oriented protrusion extending from a distal end of the shroud towards the fan casing and a clearance is formed between the protrusion and the casing defining a convoluted flow path.

A cooling-fan-apparatus fan shroud includes: a cover wall that closes a space between a heat exchanger and a circumference of a fan; and a passing permitting frame part that is positioned between the fan and an attachment part to a vehicle at an outer side of the cover wall and that allows free passing of traveling air, wherein a reinforcement rib is provided at an opening of the passing permitting frame part, and at least part of the reinforcement rib is a deflection louver that guides the traveling air to a predetermined direction.

The invention relates to an interconnection device (1) for a rotary electric machine (100), which device is intended to provide an electrical connection between a stator (2) comprising coils (20) and an electronic power-supply and control module (3), the interconnection device (1) comprising an insulating body (5) and a plurality of connecting members (400) which are arranged on an outer side (55) of the insulating body, each connecting member comprising a body (40) and a connection tongue (41) to at least one coil.

At least one combined connecting member further includes a linking lug (42) which is configured to electrically connect at least one coil (20) to the electronic module (3), said linking lug extending the body by being sized so as to cross the insulating body and so that the free end (420) of the linking lug (42) extends from an inner side (56) of the insulating body.

The present invention relates to an air conditioner for a vehicle, which takes up less installation space due to its compact-sized structure and effectively performs cooling and heating with a simple structure. The air conditioner for a vehicle includes: a case (10) having an air inflow port and an air outflow port; a blower for introducing air into the air inflow port to send the air into the case (10); a compressor (30) for compressing refrigerant; a heat exchanger for exchanging heat between refrigerant and air; and an expansion means for throttling the refrigerant, wherein the blower, the compressor (30), and the heat exchange are arranged inside the case (10) side by side to be formed in a flat type.

A vehicle climate control unit with an evaporator, a heating heat exchanger as well as a blower, characterized in that, in the direction of the air flow, are disposed, upstream of the blower on the suction side, the evaporator and the heating heat exchanger, and that an additional heating heat exchanger is disposed downstream of the blower on the pressure side.

A sump for an evaporator is disclosed. The sump may comprise: a sump housing comprising an upper end and a lower end, wherein the upper end comprises an opening and the lower end comprises a floor having a drain; and a tray located within the opening, wherein the tray comprises a base and a plurality of partitions extending from the base towards the floor, wherein the plurality of partitions divide the sump housing into chambers in acoustic communication with one another via a gap at a distal end of each of the plurality of partitions, wherein each gap defines a spacing between the respective partition and the floor, wherein, when noise enters via the drain, the sump housing and tray reduce acoustic noise which exits the sump.

A fan shroud includes a bell mouth portion and a rectangular portion. The bell mouth portion includes a circular wall that defines a discharge port and accommodates a propeller fan. The rectangular portion defines a suction port and includes a close wall close to the circular wall, and a farther wall farther from the circular wall than the close wall is from. The close wall includes a closest portion closest to the circular wall in the close wall, and a pair of connection portions connected to the farther wall. The closest wall is between the pair of connection portions. The fan shroud includes an opening portion extending through the rectangular portion from inside to outside of the rectangular portion. At least one of the pair of connection portions includes the opening portion, and the closest portion does not include the opening portion.

A vehicle airflow system includes a centrifugal fan and an air diffuser. The centrifugal fan is configured to direct air radially outward from a rotational axis of the fan. The air diffuser has a plurality of air deflectors that are disposed radially about the fan. The air deflectors have curved surfaces. Each curved surface defines an airflow channel that has an inlet extending radially outward from a periphery of the centrifugal fan and an outlet extending axially away from the diffuser relative to the rotational axis of the fan.
