Protective seal for coil fins of an air conditioning condenser unit

Abstract

A protective seal removably fits onto the top of coil fins of a condenser unit for an air conditioning system. The protective seal has a U-shaped cross-sectional configuration that allows the protective seal to fit over and completely cover the entire top edges of the coil fins and to extend partially down the front and rear sides of the coil fins to cover an upper portion of the front and rear sides of the coil fins. The protective seal is further structured to follow the contour of the top edges of the coil fins around all sides of the condenser unit to protect the top edges and the upper portion of the front and rear sides of the coil fins when the top lid of the condenser housing is both hinged open and closed.

Claims

1. A condenser unit for an air conditioning system comprising: a compressor; a condenser coil; an exhaust fan including a fan motor and fan blade; a condenser housing surrounding the compressor, the condenser coil and the exhaust fan, and said condenser housing including a base, a top lid and a plurality of vertical panels extending upwardly between the base and the top lid and defining side walls of the condenser housing; a condenser fin arrangement surrounding the condenser coil and having a top end, and the condenser fin arrangement including a plurality of flat condenser fins extending vertically between the base and the top lid in spaced, parallel relation to each other, and the condenser fins including top edges, front edges and rear edges; and a removable protective rubber seal having a U-shaped cross-sectional configuration that fits over and completely covers the entire top edges of the condenser fins and the removable protective rubber seal extending partially down the front and rear edges of the condenser fins to cover an upper portion of the front and rear edges of the condenser fins, and the protective rubber seal being bendable to freely follow the contour of the top end of the condenser fin arrangement to allow for attachment and removal of the protective rubber seal over the top end of the condenser fin arrangement, and the removable protective rubber seal protecting the top edges and the upper portion of the front and rear edges of the condenser fins when the top lid of the condenser housing is both hinged open and closed.

2. The condenser unit as recited in claim 1 wherein the removable protective rubber seal is structured and disposed to conform to and follow a curved direction of the top end of the condenser fin arrangement.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) For a fuller understanding of the nature of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings in which:

(2) FIG. 1 is a top plan view of an air conditioner condenser unit with the lid removed and showing the protective seal fitted onto the top of the coil fins of the condenser unit; and

(3) FIG. 2 is an isolated perspective view showing the lid of the condenser unit partially opened and the protective seal fitted over the top of the coil fins and extending partially down the front and rear sides of the coil fins.

(4) Like reference numerals refer to like parts throughout the several views of the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(5) The condenser unit of the present invention is shown throughout the several views of the drawings and is generally indicated as 10.

(6) The condenser unit 10 includes a protective housing 20 that surrounds the condenser coil 30, coil fins 32, exhaust fan, compressor 40 and electrical components and connections. The housing 20 includes a top lid 22 with spring hinges that allow the top lid 22 to open and stay open by itself. The condenser unit lid 22 further includes a padlock hasp 50 that allows the lid 22 to be locked when the lid is closed, thereby preventing tampering. The lid 22 may also include an electromagnetic lock (EM) 52 to keep it closed, preventing the unit from being opened when it is powered as a safety measure.

(7) A fan bracket includes struts 62 that support a motor socket 54. The bracket is easy to unlock with use of a flathead screwdriver. There are latches 66 at the four corners 68 of the condenser unit, and the fan bracket sits in all four corners with the EM lock facing the front. A rubber seal on an inside of a seal cap 70 prevents moisture from getting inside the fan motor. The coil fins 32 are protected by a removable molded rubber seal 76 that follows the contour of the top end of the coil fins 32. As seen in FIG. 2, the protective rubber seal 76 has a U-shaped cross-sectional configuration and is structured and disposed to fit over and completely cover the entire top edges of the coil fins 32. The U-shaped configuration allows the protective rubber seal 76 to extend partially down the front and rear sides of the coil fins 32 to protectively cover an upper portion of the front and rear sides of the coil fins 32. The protective rubber seal 76 is further structured and disposed to follow the contour of the top edges of the coil fins to protect the top edges and the upper portion of the front and rear sides of the coil fins when the top lid 22 of the condenser housing 20 is both hinged open and closed.

(8) While the present invention has been shown and described in accordance with a preferred and practical embodiment thereof, it is recognized that departures from the instant disclosure are fully contemplated within the spirit and scope of the present invention which is not to be limited except as defined in the following claims.
