Abstract
Abstract A heat exchange unit for use with an air conditioning system having an enclosure defining an opening, a heat exchanger within the enclosure and a grille adapted mounted to the enclosure at the opening, the grille having segments extending between a solid center portion of the grille and an edge portion such that slots are created between adjacent segments. A fan motor is suspended from the center of the grille and a special louver segment is created extending from the fan motor to the edge portion. This louver segment includes inclined segments which coact with a wire guide for forming a wire securing cavity extending from the fan motor to the control section of the unit. This combination louver configuration and wire guide acts to secure the wire in a preselected position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
A heat exchange unit including a heat exchanger which comprises: a fan orifice, a fan powered by an electric motor for coacting with the fan orifice for circulating a heat transfer medium through the heat exchanger of the heat exchange unit, a grille covering the fan orifice to allow heat transfer medium to flow therethrough while preventing foreign objects from being inserted therein, said grille including a portion extending from the fan motor to the fan orifice, an electrical power source entering the heat exchange unit a distance from the electric motor, at least one electricity carrying conductor connecting the electric motor to the power source, and a wire guide extending between the fan orifice and the electric motor, said wire guide coacting with the portion of the grille extending from the fan motor to the fan orifice to define a cavity wherein the conductor connected to the electric motor is secured.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
60 words
The apparatus as set forth in claim 1 wherein the grille further includes a radially extending louver having a relatively flat portion and two louver inclined segments each extending from one edge of the flat portion and wherein the wire guide coacts with the two inclined louver segments and the flat louver portion to define a cavity for the conductor.
Claim 4
Dependent Claim
65 words
The apparatus as set forth in claim 2 wherein the wire guide further comprises: a wire guide bottom portion, a first wire guide lip extending from the wire guide bottom portion at an angle thereto to engage a louver inclined segment, and a second wire guide lip extending from the wire guide bottom portion at an angle thereto to engage the other louver inclined segment.
Claim 5
Dependent Claim
76 words
The apparatus as set forth in claim 3 wherein the wire guide further comprises a wire guide inclined portion extending downwardly from the wire guide bottom portion, two wire guide side portions extending upwardly one from each edge of the inclined portion and a wire guide fastening portion extending from one side portion, the inclined portion and two side portions forming a conductor receiving entryway for receiving the conductor where it is connected to the motor.
Claim 6
Dependent Claim
22 words
The apparatus as set forth in claim 4 wherein the wire guide fastening portion is secured to the grille by fastening means.
