A dual fan blower module of the present invention includes a housing defining a central motor compartment and first and second scroll chambers. The scroll chambers are axially aligned with and located on opposite sides of the motor compartment. A motor is mounted within the motor compartment and has first and second shaft ends extending axially therefrom. The first shaft end extends into the first scroll chamber and the second shaft end extends into the second scroll chamber. A first fan is mounted onto the first shaft end within the first scroll chamber for rotational movement within the first scroll chamber and a second fan is mounted onto the second shaft end within the second scroll chamber for rotational movement within the second scroll chamber. Each of the first and second scroll chambers includes an expansion channel extending axially inward toward the motor.

A method for dynamically balancing a centrifugal blower fan wheel is disclosed. The method includes the steps of determining an amount and location of change in the fan inlet ring of the blower wheel which is required to balance the blower wheel. Once this determination is made, the radial thickness of the inlet ring is increased at a predetermined location to provide the proper amount of balance to the blower wheel. A mold is described for accomplishing this method.

A centrifugal blower assembly for a heat exchanger system of an automotive vehicle is described. The centrifugal blower assembly includes a diffuser section interposed between the centrifugal blower housing and a heat exchanger housing in the heat exchanger system. The diffuser section has a pair of non-linear, curved side walls which allow for expansion of the air flowing therethrough to minimize air flow separation against the side walls of the diffuser.

A centrifugal blower assembly is disclosed. The blower assembly includes a centrifugal fan driven by an electric motor. The blower assembly housing includes a pre-swirler having a plurality of guide vanes which impart a predetermined amount of rotation to a volume of air as the air enters the centrifugal blower assembly. The guide vanes are disposed in a ring at the air inlet of the blower housing.
