Abstract

Vertical support for the coil within a base pan is provided by way of a plurality of raised support surfaces that are formed to define on the radially outward side an opening that facilitates the inwardly extending fastener which secures the protective grille to the base pan skirt. Damage that might otherwise be caused to the coil by the fastener, is thus avoided.

Claims

1. In an air conditioning apparatus of the type having at least one heat exchanger coil mounted above and being supported by a base pan having a grille attached to its periphery by a fastener, an improved coil support means comprising:

a riser portion being integrally formed with and extending upwardly from the base pan; and

a support portion integrally formed with said riser portion, and being substantially horizontal and adapted to vertically support the weight of the coil,

wherein said riser portion is so formed as to define a cavity for receiving the end of the fastener projecting inwardly from the grille and base pan periphery.

2. A coil support as set forth in claim 1 wherein there is attached to said support portion a nonmetallic portion to prevent chemical reaction between the coil and the support means.

3. A coil support means as set forth in claim 1 wherein said coil support means is adapted to support multiple coils.

4. A coil support means as set forth in claim 1 wherein said base pan includes a plurality of drainage openings and further wherein said coil support means is disposed between a pair of said openings.

7. An improved coil support structure as set forth in claim 1 wherein said support portion is supported on at least two sides, and said riser portion comprises at least two generally upwardly extending walls that integrally connect the support portion to the base pan.

5. In an air conditioning apparatus of the type having a base pan, a heat exchanger coil supported by the base pan, and a grille mounted by way of a fastener to a portion of the base pan to enclose the coil, an improved coil support structure comprising:

a substantially horizontal support element for placement between the base pan and heat exchanger coil so as to provide vertical support for the coil;

a riser element connected to said horizontal support element and extending downwardly to engage the base pan, said riser element being formed so as to define, on the radially outer side of the coil support structure, a cavity for receiving the end of the fastener therein; and

attachment means for attaching said support and riser elements to said bar pan, wherein said attachment means comprises a stem connected to and extending downwardly from said riser element to project through a hole formed in the base pan, and an enlarged portion extending further downwardly from said stem portion and being larger than said opening, said enlarged portion being deformable to permit its insertion through said opening and then acting, in its undeformed state, to retain the coil support in its installed position.

6. An improved coil support structure as set forth in claim 5 wherein said substantially horizontal support element includes a nonmetallic portion in direct contact with said coil.

8. An improved coil support structure as set forth in claim 5 wherein said coil support structure is composed of an elastomeric material.

9. An improved coil support structure as set forth in claim 5 wherein said riser element comprises a pair of crossed, diagonal ribs that form a triangular cavity therebetween.

10. An improved coil support structure as set forth in claim 5 wherein both said stem and said opening are formed with at least three sides, and wherein the sides of the stem conform with those of the opening, such that the relative rotational positioning is maintained to ensure that the cavity is aligned with the fastener.
