Abstract: An extruded aluminum deck plank includes a pair of longitudinally extending parallel tubular plank halves interconnected by a web extending between the lower walls of the plank halves. The inner side walls of the plank halves and the web define a U-shaped channel adapted to receive fasteners that are inserted vertically into the channel, through the web and into underlying deck plank supports. A closure strip for the channel snaps into the top of the channel to provide a smooth top surface for the deck plank and to close off the channel. The channel may be lighted and/or heated with an appropriate energy source enclosed in the channel.

Abstract: A combined diesel engine exhaust gas and charge air cooler utilizes an all-aluminum construction and a high temperature and corrosion resistant internal coating.

Abstract: A heat exchanger assembly for an internal combustion engine charge air cooler is formed from a plurality of aluminum modules, each provided with longitudinal through bores and opposite outer face portions with toothed heat exchange fins positioned in face-to-face relation. The assembly of tubular modules is interconnected with upper and lower aluminum header plates which receive the ends of the tubular modules and are secured thereto with fused joints made from the parent material of the modules and header plates. The openings in the header plates for the modules are flanged and have a thickness of at least about 0.090 inch and the wall thickness of the ends of the tubular modules also have a minimum thickness of about 0.90 inch such that the fused joints utilize substantially equal amounts of aluminum material from the modules and the header plate flanges.

Abstract: A non-prismatic heat exchanger with a modular construction for use with an engine which utilizes a coolant fluid. The heat exchanger includes a pair of unitary, non-prismatic-shaped headers spaced from one another and connected by a plurality of unitary, extruded heat exchanger modules. The headers and modules enclose a rotary fan within the interior of the heat exchanger. The fan is mechanically driven by the engine to draw cooling air into the interior of the heat exchanger and to concurrently force the cooling air outwardly between the heat exchanger modules to thermally contact and remove heat from the heated coolant fluid flowing through the modules.

Abstract: A heat exchanger assembly designed for use as a fluid cooler formed of a first metal that includes a dissimilar metal connection allowing the exchanger to be utilized and reliably secured to another structure formed of a second metal. The assembly provides an easy way to cool engine exhausts, oil or another fluid flowing through the exchanger by transferring its heat to a cooling fluid flowing around the exchanger, or vice versa. The exchanger of the assembly is formed from a number of heat exchanger modules. In an embodiment intended particularly to cool diesel engine exhaust for a turbocharger, a steel or stainless steel exhaust inlet/outlet cap which is exposed to the high temperature exhaust is demountably attached to an all-aluminum heat exchange unit connected to the engine cooling system. The high temperature exhaust and the engine coolant follow generally parallel vertical paths through the heat exchanger in a generally U-shaped path that permits a short compact construction.

Abstract: A modular heat exchanger includes a plurality of tubular modules formed from an aluminum extrusion. Each extruded tube has a generally rectangular cross section, a through bore extending longitudinally therethrough between parallel opposite faces, and parallel longitudinal V-grooves in the faces, all formed in the extrusion process. Each face includes a plurality of parallel fins which are cut into the grooved face in a direction transverse to the grooves. The fins have a generally saw tooth structure so as to increase the turbulence of the air flow through the heat exchanger. Unslotted end faces on the tubes include groove portions which are filled with weld material in both the tube joining process and the end tank welding process, thereby providing an all-welded aluminum heat exchanger of substantially enhanced strength. In another embodiment utilizing an all-welded construction, extended unslotted end faces are cross bored and sealed to provide fluid supply in lieu of the end tanks.

Abstract: A modular heat exchanger for a fluid flow is provided. The modular heat exchanger includes a plurality of modules formed from a heat transfer material. Each module has a generally rectangular cross section and a through bore extending longitudinally therethrough between parallel opposite faces. Each face includes a plurality of parallel fins extending fully across the face in a direction transverse to the longitudinal axis of the through bore. The fins have a generally saw tooth structure so as to increase the turbulence of the air flow through the heat exchanger.

Abstract: A modular heat exchanger includes unitary finned tubular core elements which can be assembled into a multi-module heat exchanger without any brazed, soldered or welded connections or mechanical connectors. The modules are preferably made from extruded aluminum blocks into which the heat exchanging fins are cut or cold formed and into the ends of which flow accumulating passages are bored. The modules are assembled with a high strength adhesive sealant which simultaneously secures the modules together and seals the peripheries of the bored passages at the module interfaces.

Abstract: A modular heat exchanger includes unitary finned tubular core elements which can be assembled into a multi-module heat exchanger without any brazed, soldered or welded connections. The heat exchanger may be constructed to be fully disassemblable or, in another embodiment, larger subassemblies of modules welded together may be used to provide units which are partly disassemblable to effect easy field replacement. The modules are preferably made from extruded aluminum blocks into which the heat exchanging fins are cut and into the ends of which flow accumulating passages may be bored. The modules are clamped together with tie rods and the sealed joints are positioned to be automatically compressed into sealing engagement upon tightening the tie rods.

Abstract: An assembly for mounting a plurality of modular heat exchangers between respective pairs of fluid openings in parallel opposed faces of an inlet header and an outlet header, including modules providing generally axial flow between the headers, each of which modules has an axially extending sleeve defining a fluid opening on one end and an end flange defining a fluid opening on the opposite end, and an end chamber having an axially flexible end wall and forming a connection between either or both of the end sleeve and the end flange and the heat exchanging portion of the module, the assembly including compressible sealing members attached to the end sleeve and the end flange and compression type mounting brackets by which the sealing members are compressed to seal the interface and provide a demountable connection between the module and the headers.

Abstract: A demountable connector assembly for a modular heat exchanger permits individual modules to be removed and replaced without replacement of the entire heat exchanger core. As applied to heat exchanger modules of conventional tube and header construction, an end chamber on each end of the module has a thin flexible wall which allows axial extension of the module when it is installed between parallel inlet and outlet header surfaces to obviate the imposition of damaging stresses on the soldered connection joints between the heat exchanger tubes and the header plates. Stabilizing rubber cushions are placed between the flexible end walls of the module and its adjacent mounting bracket to prevent excessive modular movement and to dampen vibrations.

Abstract: A heat exchanger for various kinds of liquid and gaseous fluids includes a tubular conduit having a corrugated heat exchanging outer wall and a series of shaft-mounted turbulator units mounted for rotation within the conduit on the axis thereof. Each of the turbulators diverts a portion of the flow through the tubular conduit and directs it radially outwardly into contact with the heat exchanging wall of the conduit. In a preferred embodiment, the turbulator provides a recirculation of a portion of the fluid flow by directing it in an upstream direction within the turbulator for radial discharge from the upstream end thereof and return downstream flow. The heat exchanger may be used in place of conventional automotive heat exchanging radiator constructions and may utilize welded or unitary constructions that eliminate troublesome soldered construction typical of the prior art.
