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.
A housing, for an expansion unit of a cooling system, which has a bottom wall, a top wall, and end walls, said walls coacting to define a space within said housing which is dimensioned to accommodate said expansion unit, and an air-guiding member at one side of said housing, said air-guiding member having a partition thereon intermediate two scrolls for multi-vane blowers, said partition having those edges thereof which are adjacent said scrolls relieved to enable air, which exits from said scrolls, to move toward the longitudinal center of said partition as it passes from said air-guiding member into said space within said housing.
A housing, for an expansion unit of a cooling system, which has a bottom wall, a top wall, and end walls, said walls coacting to define a space within said housing which is dimensioned to accommodate said expansion unit, said housing having an opening at one side thereof, a supporting member adjacent the lower edge of said opening, and an air-guiding member that is disposable in engagement with said supporting member to receive support from said supporting member when said air-guiding member is disposed adjacent said one side of said housing to substantially close said opening, said supporting member helping provide a desired orientation of said air-guiding member with said opening and also facilitating the securement of said air-guiding member to said housing.
A housing as claimed in claim 13 wherein a second supporting member is adjacent the upper edge of said opening, wherein said air-guiding member is disposable in engagement with and receives support from said second supporting member when said air-guiding member is disposed adjacent said one side of said housing to substantially close said opening, and wherein said second supporting member also facilitates said securement of said air-guiding member to said housing.
A housing as claimed in claim 13 wherein said supporting member defines a groove that extends generally parallel to said lower edge of said opening to provide support for said air-guiding member at points along the length of said air-guiding member.
A housing, for an expansion unit of a cooling system, which has a bottom wall, a top wall, and end walls, said walls coacting to define a space within said housing which is dimensioned to accommodate said expansion unit, said housing having an opening at one side thereof, a transition member which is disposed adjacent said one side of said housing to fill said opening, said transition member being adapted to receive air from said expansion unit and to distribute said air, said housing having a surface at said one side thereof which extends around and helps define said opening, said transition member being one of a plurality of individually-different transition members, each of said individually-different transition members having a complementary surface thereon which is engageable with said surface at said one side of said housing to enable said transition member to fill said opening.
A housing, for an expansion unit of a cooling system, which has a bottom wall, a top wall, and end walls, said walls coacting to define a space within said housing which is dimensioned to accommodate said expansion unit, said housing having an opening at one side thereof, and an air-guiding member that is disposed adjacent said one side of said housing, said housing having a surface at said one side thereof which extends around and helps define said opening, said air-guiding member having a surface thereon which is complementary to said surface at said one side of said housing and which is engageable with said surface at said one side of said housing to enable said air-guiding member to substantially close said opening, said housing having a first set of fastener-receiving openings therein, said housing having a second set of fastener-receiving openings therein, and said air-guiding member having a set of fastener-receiving openings therein which can be set in register with said first set or said second set of fastener-receiving openings in said housing, said surface of said air-guiding member blocking said first set of fastener-receiving openings in said housing whenever said set of fastener-receiving openings in said air-guiding member is set in register with said second set of fastener-receiving openings in said housing, said surface of said air-guiding member blocking said second set of fastener-receiving openings in said housing whenever said set of fastener-receiving openings in said air-guiding member is set in register with said first set of fastener-receiving openings in said housing.
