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. Two sets of fastener-receiving openings are provided adjacent the rear opening in the housing; and a complementary set of fastener-receiving openings in the air-guiding member can be disposed in register with either of those sets of fastener-receiving openings. When the complementary set of fastener-receiving openings in the air-guiding member is disposed in register with either of the sets of fastener-receiving openings in the housing, that air-guiding member will block the other set of fastener-receiving openings. Supports are provided on the housing adjacent the upper and lower edges of the opening to hold the complementary set of fastener-receiving openings of the air-guiding member in position adjacent either of the two sets of fastener-receiving openings in the housing, so a workman can use both hands to set fasteners that will hold the air-guiding member in assembled relation with the housing.
