Abstract: A system for cooling charge air from a turbo- or supercharger and exhaust gas recirculated from an exhaust gas recirculation valve in an internal combustion engine. The system includes a rdiator and parallel charge air and exhaust gas heat exchanger units, the charge air heat exchanger unit having aluminum tubes and fins for air cooling the charge air, and the exhaust gas heat exchanger unit having stainless steel tubes and fins. The charge air heat exchanger and the exhaust gas heat exchanger units are each disposed adjacent the radiator, on the same or opposite sides. Alternatively, there is provided a pair of combined charge air cooler and exhaust gas cooler heat exchanger units, with a first heat exchanger unit having stainless steel tubes and fins, and a second heat exchanger unit having aluminum tubes and fins. The heat exchanger units are disposed on opposites sides of the radiator.

Abstract: A combined radiator and charge air cooler package includes a radiator having upper and lower portions for cooling engine coolant and a charge air cooler having upper and lower portions for cooling charge air. The upper charge air cooler portion is disposed in overlapping relationship and adjacent to the upper radiator portion, and the lower charge air cooler portion is disposed in overlapping relationship and adjacent to the lower radiator portion. The upper charge air cooler portion and the lower radiator portion are aligned in a first plane, and the lower charge air cooler portion and the upper radiator portion are aligned in a second plane, behind the first plane. Ambient cooling air may flow in series through the upper charge air cooler portion and the upper radiator portion, and also through the lower charge air cooler portion and the lower radiator portion.

Abstract: A combined radiator and charge air cooler package comprises a radiator for cooling engine coolant, and a charge air cooler for cooling charge air having upper and lower portions. The upper charge air cooler portion is disposed in overlapping relationship and adjacent to the upper end of the radiator, and the lower charge air cooler portion is disposed in overlapping relationship and adjacent to the lower end of the radiator, on the face side thereof. Ambient air may flow in series through the upper end of the radiator and the upper charge air cooler portion, and through the lower charge air cooler portion and the lower end of the radiator. The charge air cooler portions are operatively connected such that the charge air may flow between the lower manifold of the upper charge air cooler portion and the upper manifold of the lower charge air cooler portion.

Abstract: A radiator includes a core for cooling a fluid, and a tank connected to the core having a side surface with a depression extending between the front and rear surfaces adapted to receive a hose and a plurality of integral ribs formed on the tank external surfaces. The radiator further includes an elongated support member having a body portion removably connected to the core and extending along a side thereof, an end portion removably connected to the tank, and a flexible expansion portion permitting relative movement between the body and end portions to reduce stress during thermal expansion and contraction of the core.

Abstract: A heat exchanger package for a motor vehicle includes a radiator and charge air cooler, each having a length between opposite ends and including front and rear opposite faces through which air flows. Each has an overlapping fluid-cooling portion at one end, wherein the rear face at one end of the radiator is disposed adjacent the front face at one end of the charge air cooler, such that the air flows sequentially in series through the overlapping portions of each. Each further has a non-overlapping fluid-cooling portion at the opposite end wherein the rear face at the opposite end of the radiator extends outward of the charge air cooler and the front face at the opposite end of the charge air cooler extends outward of the radiator, such that the air flows singularly and in parallel through each of the non-overlapping portions.

Abstract: A flux-sensitive magnetic head employs, at its back part, a structure having a thin single domain magnetic film coated thereon. A first coil wraps around the coated structure; and a second coil wraps around one pole of the head. A direct current is passed through the second coil, thereby to apply an easy axis magnetic bias to the film. By appropriately contouring the back gap of the head, signal flux appearing at the head front gap asserts a differential magnetic force to the easy axis of the film, thereby causing the inductance of the first coil to vary detectably.
