A method for the production of a shielded impeller is provided, The shielded impeller can be produced quickly and inexpensively by this means.

Method for the production of a shielded impeller, shielded impeller and fan

The invention relates to a fluid pump for conveying coolant. The fluid pump comprises an electric motor, a motor housing and an impeller. The motor has a shaft, a rotor, and a stator, and is inside an interior space in the motor housing. The impeller is connected to the shaft in the motor for conjoint rotation. The rotor has numerous blades on one side, which form a radial fan for conveying air inside the interior space.

Fluid pump

A fan wheel for propelling cooling air for an internal combustion engine, including a hub on which a plurality of fan blades is arranged and which includes a rib structure that extends peripherally and has substantially rectangular and flat ribs having an edge region. The ribs sit on the hub by the edge regions thereof and have a longitudinal direction that extends substantially tangentially to the circumferential direction of the hub, the ribs being in contact with one another.

A motor vehicle may include a radiator arrangement. The radiator arrangement may include a radiator grill having a cooling air inlet and a radiator arranged behind the cooling air inlet with respect to a forward traveling direction. A flow-directing device may be arranged to direct a cooling air flow from the cooling air inlet to the radiator. The flow-directing device may include at least one baffle element disposed on a radiator-grill side of the radiator arrangement and at least one other baffle element disposed on a radiator side. Additionally or alternatively, the flow-directing device may include a bellows arranged on the radiator-grill side or on the radiator side. Additionally or alternatively, the flow-directing device may include at least one rail including a groove and at least one rail baffle element guided in the at least one guide groove.

Motor vehicle having a radiator arrangement

A fan, with fan blades, especially used for the cooling of a motor vehicle, with the fan blades being fixed to a fan hub. In spite of being made of only a small amount of material, the fan is highly resistant to the flow conditions in the motor vehicle, each fan blade being bent rearwards at an angle in the direction of a blade root, an angled region of the fan blade being at least partially bent downwards towards the fan hub.

Fan comprising fan blades

Fan system, in particular for a heat exchanger, which fan system has at least one receptacle for a fan drive unit, at least one housing wall, and at least one strut, in particular a number of struts which connect the receptacle to the housing wall, wherein the struts are arranged between at least one heat exchanger and at least one fan wheel, wherein at least one strut has a strut end section which is configured as a flow guiding face and has an angle &#x3b1; with respect to a fan-wheel axis direction.

Fan system, heat exchanger module, method for manufacturing a fan system and/or a heat exchanger module

The invention relates to an axial fan, in particular for radiators of motor vehicles, the axial blades being fastened to a fan hub, and the fan hub in turn being connected to a viscous fluid friction clutch. According to the invention, air-guide elements or guide blades are arranged in the hub region on the front side or suction side of the axial fan. These air-guide elements or guide blades deflect the flow from the front side to the rear side of the blades and thereby stabilize the flow. To further improve the flow conditions, the hub region is covered by a cap on its front side. The cooling-air flow on the front side of the viscous fluid friction clutch and the hub flow of the fan are stabilized by the air-guide elements in combination with the
