In the past, the condenser has been attached to the base plate by means of removable fasteners, such as bolts or threaded studs that extend through openings in the base plate and are secured by means of nuts and washers fastened from underneath the base plate. This not only increases the parts count for the condensing unit but increases assembly time due to the necessity of attaching the various fasteners.
- In the present invention, the condenser or other component is attached to the base plate by means of integral torque tabs that are twisted underneath the base plate to draw the condenser or other component downwardly against the upper surface of the base plate. In a preferred embodiment, the torque tabs are located on the lower ends of the condenser or other component end plates. The tabs are preferably designed to be machine twisted to provide enough holding force to maintain the condenser or other component and base plate in a rigid condition.
- In one form thereof, the present disclosure provides a condensing unit, including a base plate having a plurality of components mounted on an upper surface thereof, the components including a compressor and a condenser. At least one of the components includes a plurality of tabs extending through a corresponding plurality of slots in the base plate. The tabs include distal portions that are twisted underneath the base plate, and the tab distal portions include respective camming surfaces that tightly engage an undersurface of the base plate to tightly fix the at least one component to the upper surface of said base plate. In a preferred embodiment, the condensing unit includes a base plate having a condenser mounted on an upper surface thereof, the condenser including a plurality of tabs extending through a corresponding plurality of slots in the base plate.
- In another form thereof, the present disclosure provides a condensing unit including a base plate having an undersurface and a condenser mounted on an upper surface thereof, the condenser including one or more attachment elements extending through one or more corresponding attachment receiving means in the base plate. The one or more attachment elements include means for engaging the base plate such that, upon deformation, the one or more attachment means tighten against the undersurface of the base plate.
- In yet another form thereof, the present disclosure provides a method of attaching a condenser of a condensing unit to a base plate of the condensing unit, the method including the step of positioning the condenser to abut a base plate, the condenser having a plurality of tabs, each tab having an internal distal upper edge, and the base plate having an undersurface. The method further includes the step of aligning each tab with a corresponding slot on the base plate. The method further includes the steps of inserting each tab through the corresponding slot one the base plate such that each tab extends through the corresponding slot, and then twisting each tab to thereby draw the internal distal upper edge of each tab tightly against the undersurface of the base plate such that the condenser is locked to the base plate.
