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.

Abstract: An improved heat exchanger, and, particularly, for an automotive vehicle, is disclosed. The heat exchanger typically includes at least one end tank; and a plurality of spaced apart metal tubes with fins between the spaced tubes. The heat exchanger may be single or multi-pass. In preferred embodiments, the heat exchanger is arranged to be single pass or two-pass and has tubes or tube arrangements to improve heat transfer efficiency.

Abstract: The present invention relates to an aluminum heat exchanger. More particularly, the present invention relates to an aluminum heat exchanger useful for motorized power systems similar to those utilized in the automotive industry for engine heat exchange, including, in particular, radiators. In a preferred method, the flat tubes of the heat exchanger are formed from flat sheet braze material and at least one portion is formed approximately normal to the wide portion (major axis) and parallel to the minor axis of the tube.

Abstract: A fin louver design using breaking and reversal louvers whose lengths are substantially longer than the half-length of the main louver but at slightly lower angles to the fin face, in order to increase the heat transfer while reducing or minimizing the airside air pressure drop. The reversal louvers will not dramatically change the airflow direction but rather permit air to follow the louver direction, thus preventing any dead area where the air speed is approximately zero in the central part between the two reversal louvers. Contact is provided between fresh moving air and the central part between the two reversal louvers.

Abstract: A heat exchanger apparatus includes a first and second coolant tanks spaced apart from each other, a plurality of heat exchanging tubes extending between the tanks for enabling coolant to flow from the first coolant tank to the second coolant tank and to be cooled in said tubes, and a coolant supply/return tube for enabling coolant to flow from the second coolant tank to the first coolant tank. The supply/return tube has a substantially circular cross-section. The supply/return tube has opposite end portions inserted into complementary openings in the inlet coolant reservoir and the first tank. In order to provide the proper, predetermined orientation of the supply/return tube in the heat exchanger apparatus, the supply/return tube has opposite locating members each adjacent to the end portions of the supply/return tube, so that a small, predetermined length of the end portions of the supply/return tube protrudes inside the supply/return tube.

Abstract: The structural assembly for the front end of a vehicle comprises a first part which defines headlamp mounting portions and which also has a region for locating the upper part of a cooling system. The assembly further comprises a second part, which supports the lower part of the cooling system, and further has nuts and bolts securing the two parts together.

Abstract: A side member for a heat exchanger has a portion which is adapted to preferentially break under low tension to alleviate problems caused by expansion, whilst retaining integrity under normal transport movements.

Abstract: A hydraulic cooling system and method for use in a vehicle comprises a hydraulic pump which is coupled to a hydraulic motor for driving a fan blade in operative relationship with a radiator via a hydraulic conduit. The hydraulic conduit is formed and provided to not only hydraulically couple the hydraulic pump to the hydraulic motor, but also to define a support structure for supporting the hydraulic motor in operative relationship with the radiator, without the need for additional support brackets or structure. It is envisioned that the hydraulic conduit could be pre-formed in a general pyramidal or frusto-conical shape to absorb forces exerted by the motor and so that it can easily be assembled and mounted to the fan shroud.

Abstract: A support for a cooling device which consists of a heat exchanger and a fan shroud for a cooling fan, has a resilient body portion adapted to simultaneously engage the heat exchanger and the fan shroud. Where the cooling device further comprises a second heat exchanger, such as a condenser, the support has a further portion adapted to engage the condenser. The support allows the assembled components to be protected from vibration.

Abstract: An apparatus retains and aligns an electrical ignition switch of a motor vehicle with respect to a steering column housing. A switch housing supports the electrical switch and has at least one first aperture formed therein. The steering column housing slidably receives the switch housing therein, and the steering column housing has at least one second aperture formed therein. At least one locking member is engagable within the first aperture and is moveable between a first position retracted within the aperture and a second position extended outwardly with respect to the first aperture. The locking member engages within the second aperture when the switch housing is slidably engaged and fully seated within the steering column housing and holds the switch housing with respect to the steering column housing when engaged within the second aperture. A biasing member urges the locking member toward the second position.
