Abstract: An electric motor mounting arrangement is disclosed which permits the motor to "float" within a blower housing without requiring any direct contact between the housing and the casing of the motor. This is possible because of the employment of a rubber-like gasket that supports the motor within the housing, so that only the flexible gasket makes contact with the motor. This unique gasket also provides an air space to permit air flow around the motor for heat ventilation, due to a plurality of ribs, nodes or bumps that create the air space, and in one environment, due partially to a series of aligned air slots in both the gasket and in the blower housing. The gasket together with a design configuration including spacing means prevents both halves of the motor housing from touching the motor casing, or each other, except thru a selectively dimensioned spacing means.

Abstract: A housing, for the expansion unit of a cooling system, has a top wall, a bottom wall and end walls; and those walls define a space which accommodates that expansion unit. That housing has a front opening which is filled by an air-distributing transition member; and it has a rear opening that is substantially closed by an air-guiding member. That air-guiding member can support a motor and a pair of multi-vane blowers, or it can be an angular transition for a single blower. That air-guiding member is shorter than the rear opening to provide a short space which can accommodate the supply and return headers of the expansion unit. That air-guiding member can be set in either of two predetermined positions relative to that rear opening to permit the supply and return headers to be located at either end of the housing.
