Abstract
Abstract Each of a pair of heat exchangers, such as a radiator and a condenser, includes a tubular structure defining a fluid flow path between an inlet manifold and an outlet manifold. The heat exchangers reside in juxtaposition for a unit with the respective fluid flow paths being congruently aligned along the axis of a stream of cooling medium passing therethrough. The heat exchangers are sealingly encased within a shroud for directing the stream of cooling medium through the tubular structures. The shroud, which is alternately usable with a conventional radiator, and the heat exchanger units are installed in a motor vehicle as a pre-fabricated modular cooling unit.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
360 words
A heat transfer device for placement in a stream of cooling medium and for simultaneously cooling a first circulating fluid and a second circulating fluid, said unit comprising: a) a first heat exchanger including i) first inlet means for receiving said first fluid; ii) first outlet means for emitting said first fluid; and iii) a first plurality of conduits communicating between said first inlet means and said first outlet means for conducting said first fluid along a first path of selected configuration, each of said conduits having a predetermined cross-sectional area; b) a second heat exchanger including i) second inlet means for receiving said second fluid; ii) second outlet means for emitting said second fluid; and iii) a second plurality of conduits communicating between said second inlet means and said second outlet means for conducting said second fluid along a second path of selected configuration, each of said conduits having a cross-sectional area equal to the cross-sectional area of the conduits in said first heat exchanger; and c) alignment means for detachably securing said second heat exchanger to said first heat exchanger in a predetermined superimposed relationship such that each of said conduits in said first plurality extends along an axis which is parallel to an axis extending through a corresponding conduit in said second plurality, said axes lying in a plane substantially parallel to the axis of said stream of cooling medium, wherein said alignment means includes i) a first tubular member projecting from said first inlet means; ii) a second tubular member projecting from said first outlet means in a common direction with said first tubular member; iii) a third tubular member projecting from said second inlet means in said common direction; iv) a fourth tubular member projecting from said second outlet means in said common direction; v) a first recess in one of said first inlet means and said second inlet means for removably receiving one of said first tubular member and said third tubular member; and vi) a second recess in one of said first outlet means and said second outlet means for removably receiving one of said second tubular member and said fourth tubular member.
Claim 2
Dependent Claim
360 words
A heat transfer device for placement in a stream of cooling medium and for simultaneously cooling a first circulating fluid and a second circulating fluid, said unit comprising: a) a first heat exchanger including i) first inlet means for receiving said first fluid; ii) first outlet means for emitting said first fluid; and iii) a first plurality of conduits communicating between said first inlet means and said first outlet means for conducting said first fluid along a first path of selected configuration, each of said conduits having a predetermined cross-sectional area; b) a second heat exchanger including i) second inlet means for receiving said second fluid; ii) second outlet means for emitting said second fluid; and iii) a second plurality of conduits communicating between said second inlet means and said second outlet means for conducting said second fluid along a second path of selected configuration, each of said conduits having a cross-sectional area equal to the cross-sectional area of the conduits in said first heat exchanger; and c) alignment means for detachably securing said second heat exchanger to said first heat exchanger in a predetermined superimposed relationship such that each of said conduits in said first plurality extends along an axis which is parallel to an axis extending through a corresponding conduit in said second plurality, said axes lying in a plane substantially parallel to the axis of said stream of cooling medium, wherein said alignment means includes i) a first tubular member projecting from said first inlet means; ii) a second tubular member projecting from said first outlet means in a common direction with said first tubular member; iii) a third tubular member projecting from said second inlet means in said common direction; iv) a fourth tubular member projecting from said second outlet means in said common direction; v) a first recess in one of said first inlet means and said second inlet means for removably receiving one of said first tubular member and said third tubular member; and vi) a second recess in one of said first outlet means and said second outlet means for removably receiving one of said second tubular member and said fourth tubular member.
Claim 3
Dependent Claim
25 words
The heat transfer device of claim 1, wherein said alignment means further comprises means for locating said device in a predetermined position within a shroud.
