Abstract: The present invention relates to the field of automotive heat exchangers, and, in particular, to heat exchanger tanks with headers. This invention eliminates the need for use of an inner flange on the header using a collar that also acts as a rib, thereby providing a compact foot plus header tank arrangement with lower stress on the gasket mating surface of the header and tank. The present invention also provides a method for providing improved headering means for automotive heat exchangers with plastic tanks and headers.

The plurality of exterior flow passages has at least one of an average hydraulic diameter or an average width that is i) greater than at least one of an average hydraulic diameter or an average width of the interior flow passages and ii) less than twice the at least one of the average hydraulic diameter or the average width of the interior flow passages.

Abstract: The present invention relates to the field of automotive heat exchanger assemblies, and, in particular, assemblies with cores with headers and end tanks and/or male and female connections.

Abstract: A support system for a cooling fan for a heat exchanger. A suspension system supports an inner hub inside an outer support structure. The inner hub or ring supports the fan and motor. The suspension system includes an array of spiral support arms, extending from the inner hub to the outer supports. These arms have both spanwise and chordwise camber. The particular suspension system increases natural frequencies of the support system, over that wherein purely radial arms connect the inner hub and outer supports.

Abstract: A cooling fan for a vehicle. Many engine compartments of motor vehicles are small in size, and contain numerous components. Electric cooling fans are used to draw air through a radiator. Given the cramped conditions within the engine compartment, the exhaust of the fan cannot be directed into open air, but must impinge on one or more of the components within the compartment. This situation reduces velocity in the exhaust, and also reduces efficiency of the fan. The invention provides a collection of generally co-axial stators which divert the exhaust around the components, while retaining much of the velocity of the exhaust.

In preferred embodiments of the present invention, a composition comprising at least one hollow or essentially hollow sphere or spheroidal shaped material, such as glass bubble, is found in a matrix comprised of a plastic or resin or plastic or resin like material, and is used in forming parts or components useful for automotive applications.

Abstract: An improved heat exchanger for an automotive vehicle, comprising at least one end tank; and at least two heat exchangers including a plurality of spaced apart metal tubes with fins between the spaced tubes. The heat exchangers are preferentially disposed so that their respective tubes and fins are generally co-planar with each other and are connected to the end tank. In preferred embodiments, the heat exchanger may include a radiator element.

Abstract: There is disclosed a heat exchanger for transferring heat between at least two fluids and a method for forming the heat exchanger. The heat exchanger preferably includes one or more end tanks, one or more inlets and outlets, one or more tubes, one or more fins, and one or more improved baffle combinations including at least one single piece double baffle. The improved single piece double baffles act as part of a baffle system, with advantages over multiple-piece only double baffle systems due to being assembled in one piece.

Abstract: Optimized designs of heat exchangers, and, in particular, heat exchangers and assemblies comprising multi-exchangers or combo coolers comprising different heat exchanger parts or elements, and fins or separators of different types and/or characteristics on the different tube parts of the heat exchanger results, are disclosed. The two part heat exchanger is capable of being traversed by different fluids, and fins differ in characteristics, such as height and pitch, to increase overall heat exchanger efficiency.

Abstract: A heat exchanger assembly includes a core with a header, an end tank and a joint between the header and the end tank. A seal between the header and the end tank is in an area at the joint between the header and the end tank. The seal normally produces a permanent seal except when a misalignment of the seal at the joint between the header and the end tank produces a temporary seal. At least one groove or channel is defined in the header or the end tank at the joint between the header and the end tank, for detecting the temporary seal. The at least one groove or channel extends beyond a highest point at which the temporary seal is formed. The groove or channel functions as a positive leak path between the temporary seal and the header and/or the end tank in the area at the joint between the header and the end tank.

Abstract: The present invention relates to automotive heat exchanger assemblies that can withstand high environmental temperature and pressures conditions. By providing a tube strengthener inserted into the tubes at the areas of highest stress, the heat exchanger assembly is strengthened to be efficient under typical operating conditions.

Abstract: A cooling fan for an engine in a vehicle. Ordinarily, a fan rotates within a shroud, which surrounds the fan. Leakage can occur between the tips of the fan blades and the shroud, wherein fan exhaust moves forward, and then passes through the fan again. The invention reduces leakage by placing a surface downstream of the fan. The surface employs the Coanda Effect, to urge fan exhaust to continue in the downstream direction, and not move forward as leakage air.
