Abstract

For the environment of motor-home and related roadway vehicles respectively extending along a horizontal and directionally longitudinal central-axis and that terminates as a powertrain-zone including a turbo-charged internal combustion engine vehicular powering means provided with liquid-air radiator that is coupled with an air-air radiator for cooling an airpath therealong including an intake-pipe for conveying environmental air and thence through an incoming-pipe into an engine turbo-charger for conversion into high-pressure-heated-air (HPHA). The HPHA is then conveyed along an outgoing-pipe through an airpath first-interface into the air-air radiator that converts HPHA to high-pressure-cooled-air (HPCA) emerging through an airpath second-interface via an inlead-pipe communicating within said engine, the improvements of: the parallel and coupled liquid-air and air-air radiators are together pivotably associated with framework for the engine and together pivotably movable away from the engine, the outgoing-pipe and the inlead-pipe; and the parallel, coupled, and pivotal liquid-air and air-air radiators at the airpath first-interface and second-interface are respectively provided with first-removable-coupler means and with second-removable-coupler means along the airpath to accommodate pivotal movements of the coupled liquid-air and air-air radiators.

Description

Background of the Invention

Drawing FIGS. 1 and 2 herein are identical to drawing FIGS. 1 and 2 of the parent U.S. patent application Ser. No. 07/914,476 (filed Jul. 15, 1992) now U.S. Pat. No. 5,314,205. Drawing FIGS. 1 and 2 schematically depict a motor-home vehicle skeletal chassis (e.g. 10) extending horizontally and directionally longitudinally along central-axis 10A. Consecutively longitudinally along said central-axis 10A are:

(i) a frontal-end OPERATIONAL-ZONE (i.e. underlying the vehicle's human-driver and overlying roadway-engageable front-wheels "FW") and which at 600, 610, etc., refer to linkage for connecting vehicular frontal air-springs to a single air-control valve;

(ii) a central OCCUPANTS'-ZONE (i.e. underlying vehicular passengers); and

(iii) a rearward POWERTRAIN-ZONE that through an hydrocarbon-fired engine (e.g. diesel, internal-combustion, etc.) and associated powertrain motivates roadway-engageable rear-wheels "RW". Reference character 200 generally refers to a readily-serviceable, latchable pivotably associated heat-exchanger means for cooling the said engine and for cooling the airpath ancillary to a turbocharger-type internal combustion engine, diesel engine, or the like.

Object of the Invention

In view of the foregoing, it is the general objective of the present invention to retain and incorporate, from patent application Ser. No. 07/914,476, now U.S. Pat. No. 5,314,205, and appropriately claim herein, the concept for coupling and pivotably associating liquid-air and air-air radiators for cooling the engine (of whatever type) for motor-home vehicles, and during pivotal movements of said coupled radiators to maintain ease of re-installation for said coupled radiators.

Detailed Description of the Drawing

Reference character 200 generally refers to a readily-serviceable, latchably pivotably associated (e.g. 201, 202, at engine framework 190A) heat-exchangers combination (210, 220), namely an upright liquid-air type radiator (210) for internally cooling an internal combustion engine (190) and coupled to an upright and parallel air-air type radiator (220) for cooling that portion of an airpath serially extending among: the engine turbocharger (190T); thence through first-interface 198A to air-air type radiator 220, and thence through second-interface 199A into the fueling mixture for a said engine (190), Immediately alongside thereof, the said liquid-air type radiator (210) is herein provided with a said upright pivotal hinge (201) at engine framework (190A), and also with an annular shroud 211 for longitudinally channeling an airstream (emanating from engine endward fan 190F) through said coupled, pivotal (201), and latchable (202) combination of upright radiators (210, 220). Said liquid-air type radiator (210) is conventionally provided with a liquidpath for cooling the engine internal combustion products, and which liquidpath conventionally includes a flexible upper-hose (L92) and a flexible lower-hose (193). Herein, the latching means (202) comprises a T-shaped handle carried by radiator 220 and being threadedly engageable with the engine framework (190A).

In further regard to the aforementioned airpath (e.g. 195 extending serially among the ambient atmospheric environment, the engine turbocharger (190T), the air-air radiator (220), and into the engine's internal combustion chamber: The said airpath (195) serially includes therealong: an intake-pipe (196) for thrusting ambient environmental air toward an air-cleaner (196C); an incoming-pipe (197) extending from a said air-cleaner (190C) into an engine turbocharger (e.g. 190T having turbo-charger exhaust 190TE) whereby ambient air is converted to high-pressure heated-air (HPHA) thence along an outgoing-pipe (198) through an airpath first-interface (198A) and via a secondary-pipe (198B) into air-air radiator 220 whereby HPHA is converted to high-pressure cooled-air (HPCA); and from said air-air radiator through a second-interface 199A (normally located above first-interface 198A); and finally along an inlead-pipe 199 converying HPHA into the engine's combustion chamber. Double-headed arrows in FIG. 5 directionally indicate the said airpath (195) through the lower first-interface 198A and through the upper second-interface 199A. First-interface 198A comprises mateably-telescoping tubular parts (e.g. a male part 198M carried by radiator 220 and a female member 198N carried by a said engine framework 190A). Similary, second-interface 199A comprises mateably-telescoping parts (e.g. a male part 199M carried by radiator 220 and a female part 199N carried by engine framework 190A).

In view of the foregoing technological description, it will be readily appreciated that there has been attained the sought objectives of coupling and latchably pivotably associating liquid-air and air-air radiators to the framework and airpath for internal combustion engines and whereby ease of engine and radiators servicing accomplished by expediently temporarily de-latching (202) the coupled radiators so that they can be temporarily pivoted-away (201) from the engine framework and slidably disjointed at airpath interfaces (198A, 199A).

In view of the foregoing, the construction and operation of the latchably pivotably-coupled heat-exchangers concept of the present invention will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
