Embodiment Construction

[0016]Referring now to FIG. 1, the invention is shown generally at 10 as applied to an air conditioning outdoor unit 11 having a wrap-around heat exchanger coil 12 terminating at either end by tube sheets 13 and 14. A compressor 16 is disposed within the confines of the coil 12 and is serially connected in a vapor compression cycle arrangement in a common manner. The compressor 16 is preferably a hermetic compressor with an internal electric motor for driving the compressor. A heater is also preferably provided to heat the compressor during operation in low temperature conditions. Both the drive motor and the heater are connected by electric wires 17 to a control box located outside the coil 12.

[0017]Near the top of the unit 11 there is disposed a motor driven fan 18 for drawing outdoor air radially inwardly through the coil 12 so as to be discharged upwardly to the atmosphere. The wire lead of the electric drive motor for the fan 18 is routed radially outwardly to the edge of the c...

Abstract

An outdoor unit for an air conditioner / heat pump is provided with a bracket which is attached to the tube sheet of the heat exchanger coil for routing the electrical leads from the electronic components within the unit to a control box located outside thereof. The bracket is mounted without fasteners and is preferably clipped onto a planar structure on the tube sheet by way of opposing tabs on the bracket. The bracket is preferably secured to the planar wall by way of dimples that engage with holes formed in the planar wall.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates generally to air conditioning / heat pump units and, more particularly, to apparatus for routing and retaining electrical wires therein.[0002]Air conditioning systems for conditioning residences and other interior spaces provide a condenser unit located outside the residence and an evaporator unit located in communication with the interior spaced to be cooled. In heat pump applications, a reversing valve is provided and the roles of the two units are reversed.[0003]In both air conditioner and heat pump applications, the outdoor unit has an electric motor and fan associated therewith such that the outdoor air may be drawn through the heat exchanger of the unit. In addition to the fan motor, other electrical components, such as a compressor, heater, and pressure switches, are located in the interior of the unit and are commonly connected by way of electrical wires to a control unit mounted outside of the heat exchanger coil.[0004]V...
