Abstract
Abstract A wire guide assembly for use in an air conditioning system having a heat exchange unit. A wire guide assembly acts to provide a secure cavity through which wires emanating from the control area and flowing to a separately located electrical component may pass. The wire guide assembly serves to protect the wires from engagement with either a rotating fan or a heat exchanger. The wire guide assembly includes a control area member having a T-shaped opening, a retainer and a cover slidably engaged to the retainer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A heat exchange unit comprising: support means for supporting the unit; a heat exchanger mounted to the support means and extending about at least a portion of the periphery of the unit; a fan for circulating air in heat exchange relation with the heat exchanger; means defining a control area circumferentially spaced about the fan and adjacent the heat exchanger wherein at least one electrical component of the heat exchange unit may be mounted, said means additionally defining a wire guide opening; and a wire guide connected to extend through the wire guide opening and between the fan and the heat exchanger, said wire guide defining a wire securing cavity and including means for connecting the wire guide to the means defining the control area.
Claim 2
Dependent Claim
125 words
A heat exchange unit comprising: support means for supporting the unit; a heat exchanger mounted to the support means and extending about at least a portion of the periphery of the unit; a fan for circulating air in heat exchange relation with the heat exchanger; means defining a control area circumferentially spaced about the fan and adjacent the heat exchanger wherein at least one electrical component of the heat exchange unit may be mounted, said means additionally defining a wire guide opening; and a wire guide connected to extend through the wire guide opening and between the fan and the heat exchanger, said wire guide defining a wire securing cavity and including means for connecting the wire guide to the means defining the control area.
Claim 3
Dependent Claim
35 words
The apparatus as set forth in claim 1 wherein the wire guide comprises a retainer in a U-shaped configuration and a cover adapted to be secured to the retainer to form the wire securing cavity.
Claim 4
Dependent Claim
66 words
The apparatus as set forth in claim 2 wherein the means defining the control area comprises a fan orifice annular in configuration having a U-shaped cross section within which the control area is located, and further comprising a fan mounted to revolve within the fan orifice and wherein the wire guide extends from an opening in the fan orifice between the fan and the heat exchanger.
Claim 5
Dependent Claim
78 words
The apparatus as set forth in claim 1 wherein the wire guide comprises a retainer having a retainer back wall, two retainer side walls attached to each edge of the retainer back wall, a fastening flange attached to the retainer back wall for securing the retainer to the means defining a control area and a cover adapted to be secured to the two retainer side walls to form the wire securing cavity between the cover and the retainer.
Claim 6
Dependent Claim
57 words
The apparatus as set forth in claim 4 wherein each retainer side wall has extending therefrom a retainer rail which is generally planar with the retainer back wall and wherein the cover includes a cover hook flange on each edge thereof, said cover hook flanges engaging the retainer rails to slidably secure the retainer to the cover.
Claim 7
Dependent Claim
44 words
The apparatus as set forth in claim 5 wherein the wire guide opening has a narrow portion through which the cover is inserted and connected to the narrow portion a wide portion through which the retainer with the retainer hook flanges may be inserted.
