The coil includes tube sheets provided at each end thereof, each of the tube sheets having at least one tab extending outwardly from the surface. A relatively warm medium is passed in heat transfer relation with the cold heat exchange medium, the warm medium being cooled thereby. A condensate collection pan is disposed below and extends substantially coextensive with the lower surface of the heat transfer coil to permit condensate formed on the surface of the coil to drain into the collection pan.

6 Claims, 6 Drawing Figures HEAT EXCHANGE ASSEMBLY BACKGROUND OF THE INVENTION The instant invention relates to heat exchange assemblies and in particular, to those assemblies including condensate collection pans provided to receive condensate formed on the surface of the heat exchange coil.
Heat exchange assemblies are employed in many applications wherein a relatively cold heat exchange medium is supplied to the coil of the assembly. Typical of such an application is the utilization of the heat exchange assembly as an evaporator of a refrigeration unit employed in an air conditioning system. A relatively warm medium is passed thereover to be cooled by passing in heat transfer relation with the relatively cold medium passing through the coil. As a result of the cooling of the warm medium, very often condensate is produced on the surface of the heat transfer coil.
Condensate draining from the surface of the coil must be collected to avoid pools of water from developing beneath the lower surface of the heat transfer coil. Typically, a condensate collection pan is disposed below and extends coextensive with the lower surface of the heat transfer coil.
It is the general practive to connect the condensate pan to the heat transfer coil via fasteners, such as screws or similar devices. Although fasteners such as screws satisfactorily attach the condensate collection pan to the heat transfer coil, the use of such fasteners increases the cost of producing the heat exchange assembly. By eliminating the use of conventional fasteners, substantial cost reductions may be obtained in manufacturing the heat exchange assembly.
SUMMARY OF THE INVENTION It is therefore an object of the invention to provide a heat exchange assembly including a condensate collection pan that may be readily attached to a heat transfer coil without the utilization of conventional fasteners.
It is a further object of this invention to provide means integrally formed with the condensate collection pan for attaching the pan to the heat transfer coil of a heat exchange assembly.
These and other objects of the present invention are obtained by providing a heat exchange assembly including a heat transfer coil. A relatively cold heat exchange fluid is passed through the heat transfer coil. The coil includes at least one tab means extending from each surface defining the ends of the heat transfer coil. A relatively warm medium is passed in heat transfer relation with the relatively cold heat exchange medium passing through the heat transfer coil, the warm medium being cooled, thereby resulting in the formation of condensate on the surface of the heat transfer coil. Means to collect the condensate is disposed below and extends substantially coextensive with the lower surface of the heat transfer coil to permit the condensate to drain into the collection means. The collection means includes means defining a slot at each end thereof, each of the slot defining means receives a tab extending from the heat transfer coil to secure the collection means to the coil.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawing, there is disclosed a heat exchange assembly including the invention herein disclosed. In referring to the various figures of the drawing, like numerals shall refer to like parts.
With particular reference to FIG. 1, heat exchange assembly 10 includes side walls 11 and 13, connected together by a rear wall 12, the walls forming the casing of the unit. Although not shown, it should be understood, that the casing generally includes a front wall or door spaced apart from illustrated rear wall 12. The front wall is preferably removable to permit servicing of the assembly.
A heat exchange coil 15 is disposed within chamber 14 of the casing, the chamber being defined by the front, rear and side walls. The heat exchange coil includes a plurality of plate finned members 16 which extend outwardly from tubes not shown. Each of the tubes terminate in a return bend 17. Return bends 17 are suitably connected to the various tubes so a continuous flow circuit is formed for the heat exchange medium flowing in the tubes. A suitable heat exchange medium, for example a refrigerant such as dichlorodifluoromethane, sold under the trademark Freon-12 passes through the tubes of the heat exchange coil. Tube sheets 18 and 18' are preferably provided at either end of the coil. Tube sheet 18' has tabs 19 and 20 integrally formed therewith and extending therefrom. Tabs 19 and 20 are received in slots formed in embossments 21 of rear wall 12 for securing heat exchange coil 15 within chamber 14.
When the heat exchange assembly is employed as an evaporator, the medium to be cooled, is directed over the surface of the tubes having the relatively cold medium flowing therethrough. When the medium is air, its capacity to hold moisture is reduced as its temperature is lowered; accordingly, when the air is cooled, condensate very often is formed on the surface of fins 16.
To prevent the formation of undesirable puddles of water, a condensate pan 22 is provided to collect the condensate draining from the surface of fins 16. Condensate collection pan 22 is disposed below and extends substantially coextensive with the lower surface of heat exchange coil 15.
Referring now to FIG. 2, there is shown an enlarged view of a portion of condensate collection pan 22. Pan 22 includes a suitable opening 31, which may be threaded in the manner shown, for connection to a pipe for draining the condensate collected in the pan. Pan 22 further includes a first portion 21 having a recessed section 32. A movable, upwardly extending finger 24 is disposed in an opening 33 defined in recessed section 32. As is clearly shown in FIG. 6, finger 24 includes cam or inclined surface 34 for a reason to be explained hereinafter.
Referring now to FIG. 4, there is disclosed an enlarged view of the left hand portion of the heat exchange coil shown in FlG. l. The condensate collection pan includes a second portion 26 having a recessed section 27 defining a slot or opening 28.
Referring particularly to FIGS. 3 and 5, there are shown exploded perspective views of the: portions of the condensate pan illustrated in FIGS. 2 and 4 respectively. In particular, tube sheet 18 includesan outwardly extending tab member 23 integrally formed therewith. As shown in FIG. 5, tube sheet l8includes a tab member 27 integrally formed therewith and extending outwardly therefrom.
When it is desired to secure condensatecollection pan 22 to heat exchange coil 15, tab 27 is inserted through slot 28 to secure the left hand portion of the condensate pan to the portion of the heat exchange coil disposedthereabove. Thereafter, tab member 23 of tube sheet 18 is inserted into opening 33 defined by recessed section 32. Tab member 23 rides over cam 34 of finger 24 so that the top surface of the tab member engages the bottom surface of the cam, as is shown in FIGS. 2 and 6. Tab member 23 is thus firmly locked in opening 33 of section 32. The condensate collection pan is firmly secured to the heat exchange coil without requiring the utilization of conventional fasteners such as screws. As is obvious, the elimination of such conventional fasteners will decrease the cost of manufac turing a heat exchange assembly of the type heretofore discussed. When it is desired to remove pan 22 from the coil, finger 24 is slightly depressed to permit tab means 23 to ride over cam 34.
While a preferred embodiment of the present invention has been described and illustrated, the invention should not be limited thereto; but may be otherwise embodied within the scope of the following claims.
