Abstract

A heat exchanger of the tube-fin type comprising a tank (10) having first (14) and second (16) ends, a plurality of tubes (34), a plurality of baffles (38) and a plurality of fins (42). A cap (50, 52) is connected to each end (14, 16) of the tank (10) and includes a fluid coupler (60, 61). Each cap (50, 52) comprises a female member (74) disposed therein including a plurality of interior passageways (88), first (90) and second (92) annular channels intersecting with opposite ends of the passageways (88), and a plurality of islands (94) bounded by the passageways (88) and first (90) and second (92) channels. The tank (10) further comprises a male member (72) extending from each end (14, 16) and including a plurality of outwardly extending tabs (76), an annular extending rim (82), and an annular resilient seal (84). A cap (50, 52 ) is disposed about each end (14, 16) of the tank (10) by inserting the tabs (76) into the longitudinal passageways (88) and extending the cap (50, 52) about the tank (10) until the tabs (76) intersect with the second channel (92) and rotated block the cap (50, 52) and the tank end (14, 16) together.

Dependent claims

A heat exchanger assembly comprising:

tank means (10) having a longitudinal axis extending between first (14) and second (16) ends for conveying fluid therethrough, heat exchanger means (32) disposed in said tank means (10) for removing heat energy from the fluid, attachment means (46, 47) fixed to said tank means (10) at a predetermined position extending radially from said axis for attaching said tank means (10) to a vehicle, cap means (50, 52) for closing at least one of said first (14) and second (16) ends and including a coupler (60, 61) for connection to a fluid conduit (102, 103);
said assembly characterized by including connection means (70) interconnecting said cap means (50, 52) and said one end (14, 16) of said tank means (10) for maintaining a fluid impervious seal between said cap means (50, 52) and said one end (14, 16) and for allowing relative rotation between said cap means (50, 52) and said tank means (10) to annularly adjust the position of said coupler (60, 61) with said fluid conduit (102, 103), said connection means (70) including a male member (72) having at least two tabs (76) spaced circumferentially apart a predetermined arcuate distance about said axis and a female member (74) having an interior annular channel (92) intersecting with at least two axially extending interior passageways (88) disposed parallel to one another and spaced circumferentially said predetermined distance for receiving said tabs (76) of said male member (72), said male member (72) further including an annular rim (82) and said female member (74) including at least a portion of an annular wall (94, 118) and said connection means (70) including resilient sealing means (84) compressed between said rim (82) and said wall (94, 118) for locking said tabs (76) in said annular channel (92) while establishing a fluid impervious seal therebetween and for allowing relative rotation between said cap means (50, 52) and said tank means (10).

A heat exchanger assembly of the tube-fin type comprising:

a tank (10) having a longitudinal axis extending between first (14) and second (16) ends and including a tank hot fluid inlet (18), a tank hot fluid outlet (20), a tank cooling fluid inlet (22), a tank cooling fluid outlet (24) and a hot fluid reservoir (30);
a heat exchanger (32) disposed in the tank (10) including a plurality of tubes (34) supported at each end by cylindrical headers (36, 37), a plurality of baffles (38) spaced longitudinally in the tank (10) and a plurality of fins (42) spaced closely within the tank (10);
a cap (50, 52) disposed about each end (14, 16) of the tank (10) including a coupler (60, 61) extending radially from the longitudinal axis and having a seal (62) disposed thereabout;
the cap (50) further including a cap cooling fluid inlet (54) and a cooling fluid inlet reservoir (57) and the cap (52) further including a cap cooling fluid outlet (55) and a cooling fluid outlet reservoir (58);
a connection (70) between each cap (50, 52) and each end (14, 16) of the tank (10) including a plurality of longitudinal passageways (88) disposed within the cap (50, 52), a first (90) and second (92) annular channel intersecting with opposite ends of the passageways (88), a plurality of arcuate island (94) bounded by the intersection of the first (90 and second (92) channel and the passageways (88), a plurality of radially extending tabs (76) received in the passageways (88) and further rotated into the second channel (92), the tabs (76) further defined by having an L-shaped slot (78) formed thereabout,
an annular extending rim (82) spaced longitudinally from the tabs (76), and a resilient annular seal (84) disposed between the rim (82) and the arcuate islands (94);
and
a plurality of attachments (46, 47) extending radially of the longitudinal axis and having a plurality of apertures (48) therethrough for connection to a vehicle;
the attachment (46) further including an attachment hot fluid inlet (64) in fluid communication with the tank hot fluid inlet (18) and having a duct (67) disposed thereabout for providing a fluid passageway therebetween;
the attachment (47) further including an attachment hot fluid outlet (65) in fluid communication with the tank hot fluid outlet (20) and having a duct (68) disposed thereabout for providing a fluid passageway therebetween.
