Abstract
Abstract A side mounting channel for a radiator is an integrally molded plastic unit with a shape particularly tailored to efficiently resisting the warping forces that result from thermal growth of the radiator core. Each side channel has a flat web and parallel, perpendicular edge flanges that substantially symmetric to the web. The edge flanges taper down into the plane of the web over a transition portion of defined length.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
176 words
In a vehicle having a generally four sided heat exchanger with a core having a predetermined thickness and a substantially planar configuration that is subject to warping forces in use, a channel for mounting one side of said core to said vehicle, comprising, a generally flat, substantially rectangular, molded plastic central web having an inboard side and an outboard side and an end to end length and edge to edge width comparable to said core, with each end adapted to be fixed to said heat exchanger one side, a pair of edge flanges molded integral with and substantially perpendicular to said web, said flanges being substantially symmetrical to both sides of said web and extending for less than the entire end to end length of said web, each edge flange further having a transition portion tapering down toward an end of said web and into said web in which the length of said transition portion is approximately 0.085 to 0.17 of the end to end length of said channel, whereby said warping forces are efficiently resisted.
