Embodiment Construction

[0029]With reference to FIGS. 1 and 2, an exemplary condensing unit 10 is shown. It comprises a metal base plate 12 having flanges 14 and an upper surface 16 to which are mounted a hermetic compressor 18, receiver 20 and a condenser unit 22, the latter comprising a condenser 24 and a fan assembly 26. Fan assembly 26 comprises a plastic housing or shroud 36 which houses motor driven fan 38. The discharge line 28 from compressor 18 is connected to inlet 29 of the condenser 24 and outlet 31 thereof is connected by means of tube 30 to receiver 20. Inlet and outlet ports 32 and 34, respectively, are adapted to be connected to the evaporator unit (not shown) of the refrigeration system.

[0030]Referring now to FIG. 3, condenser 24 comprises a pair of end plates 40 and 42, a serpentine coil 44 carrying a refrigerant connected to the inlet 29 and outlet 31 and in good thermal connection with a plurality of cooling fins 46 in a manner well known in the art. Coil 44 includes internal portions 4...

Abstract

The present invention relates to a condenser or other component that 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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under Title 35, U.S.C. ยง119(e) of U.S. Provisional Patent Application Ser. No. 61 / 178,089, entitled CONDENSING UNIT CONDENSER ATTACHMENT FEATURE, filed on May 14, 2009, the disclosure of which is expressly incorporated by reference herein.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to condensing units, and in particular to an attachment technique for fixing the condenser or other components to the condensing unit base plate.[0004]2. Description of the Related Art[0005]Condensing units are self-contained units typically comprising a hermetic compressor, condenser and cooling fan all mounted to a base plate and having refrigerant lines adapted for connection to a remotely located expansion valve and evaporator. 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 ...
