Abstract: A core (26) extends through a circular bend (28) greater than 180 degrees to define a first leg (30) between the bend (28) and an inlet manifold (22) and a second leg (32) between the bend (28) and an outlet manifold (24). The legs (30, 32) are disposed in converging relationship from the bend (28) towards the manifolds (22, 24) to define an acute angle (?) between the legs (30, 32). The manifolds (22, 24) are aligned in juxtaposed relationship along an alignment axis (Y) and the legs (30, 32) are disposed in angular relationship to a reference axis (X) to define first and second drainage angles (?1, ?2) between the corresponding legs (30, 32) and the reference axis (X). The second drainage angle (?2) is >10 degrees and the first drainage angle is (?1)>20 degrees and the acute angle (?) is >10 degrees for draining condensate along the legs (30, 32) toward the juxtaposed manifolds (22, 24) to establish a common drainage point of the condensate.

Abstract: A heat exchanger assembly includes an outlet header extending along an outlet axis to define an outlet cavity and an inlet header defining an inlet cavity. A plurality of refrigerant tubes extends from the inlet header through the outlet header and into the outlet cavity. A collector conduit having a generally semi-circular conduit cross-section defining an arced surface and a chord surface interconnected with rounded ends is disposed in the outlet header and includes a conduit body portion and at least one conduit end portion interconnected by a conduit transition portion with the conduit body portion being offset from the conduit end portion. The conduit body portion is engaged to an interior surface of the outlet header to space the conduit body portion from the refrigerant tubes and the conduit end portion is coaxial with the outlet header axis to provide a central outlet for the refrigerant vapor.

Abstract: A heat exchanger assembly for thermally conditioning a stream of air. The assembly includes a first and second manifolds extending in spaced and parallel relationship. A plurality of tubes extend transversly between the manifolds to establish fluid communication therebetween. A plurality of corrugated air fins is disposed between adjacent tubes with the cross-section of each air fin presenting a plurality of legs extending transversly between the flat sides of adjacent tubes. Each leg defines a plurality of front louvers including a leading half louver disposed adjacent the front edge of the leg and a plurality of leading louvers spaced from each other and from the leading half louver. A plurality of smaller trailing louvers are spaced from the leading louvers. A plurality of rear louvers being spaced from each other is disposed between the trailing louvers and the rear edge of each leg.

Abstract: A bike-holding system for transporting one or more two-wheeled vehicles in a bed of a transportive vehicle includes a first holder comprising a plate interrupted by one or more elongated slots, each slot being adapted to receive a first wheel of a two-wheeled vehicle, which first wheel may be either a front or rear wheel. The plate is inclined at an angle to the plane of the bed. The system may include a second holder comprising a second plate interrupted by one or more elongated slots or pairs of rails, each of the elongated slots or rail pairs being adapted to receive a second wheel of the two-wheeled vehicle. A two-wheeled vehicle thus installed in a holder or holders of the invention is restrained from lateral (tipping) motion or vertical motion with respect to the bed by one or more hold-downs attached to the two-wheeled vehicle and the transporting vehicle.

Abstract: An automotive dual radiator and condenser assembly with optimized structural and thermal capabilities. The two halves or layers of the dual assembly are interconnected by a pair of widely spaced, narrow webs, which webs interconnect two halves of a slotted tandem header plate unit. The webs, though small, are sufficient to maintain all components of the whole assembly properly and rigidly spaced at all times, during assembly, during brazing, and during and after installation. The two webs also represent the only significant direct heat conduction path between the radiator and condenser, so that thermal efficiency is comparable to a pair of non connected units.

Abstract: A draincock assembly is designed so it may be molded with the radiator tank. The draincock assembly includes a drain for draining fluid from the heat exchanger. The drain includes a cam surface which receives a pin of a draincock therein. The draincock moves rotationally about and axially along a longitudinal axis defined by the drain between open and closed positions in a path defined by the pin moving along the cam surface. A detent is molded to the cam surface and prevents movement of the pin of the draincock therepast unless a rotational force is applied to the handle of the draincock. An O-ring at the end of the cylindrical body of the draincock provides a seal wherein no fluid may exit through the drain nipple until the O-ring moves past the drain nipple, creating a drainage path from the radiator tank.

Abstract: An air/liquid heat exchanger having a refrigerant spray providing evaporative cooling.

Abstract: An air/liquid heat exchanger having a tube that reinforces the heat exchanger's core and header plates and also sprays a liquid onto the core for evaporative cooling.

Abstract: An air/liquid heat exchanger for aircraft having ram pressure powered evaporative cooling.

Abstract: A dust plug adapted to be retained by and sealed to the O-ring in a fluid fitting. The plug has a spherical insertion end and a shoulder remote therefrom and is retained by the O-ring between the bead and the shoulder on insertion of the plug with the shoulder also acting as a stop against the O-ring to prevent over insertion.

Abstract: The joint between the tank and header of a heat exchanger comprises a channel formed in the header having an inner wall and a bottom, and a rim or foot on the mating edge of the tank. The space between the foot and the channel bottom and inner wall contains an elastomer gasket which is shaped to allow low assembly forces to deform the gasket and fill the space between the tank foot and header pocket, even when high hardness gasket material is used. The gasket includes an enlarged rib, like an O-ring, between the tank foot and header and an integral web portion extending from the rib into the space between the inner wall and the foot to fill and seal that area as well as the area at the bottom of the foot.

Abstract: A heat exchanger header plate has a first set of strengthening ribs each located between adjacent tube slots which are formed in a second set of ribs that extend oppositely to the ribs in the first set.

Abstract: A quick connect tube coupling has a connector body with an external threaded portion and a passage extending therethrough. A sheet metal nut and tube retainer member has an opening therethrough with a helical edge engaging the external threaded portion to threadably connect the connector body and this member. The connector body passage is adapted to receive and telescopically pilot a tube end on opposite sides of an O-ring mounted in a groove in this passage. The O-ring is adapted to receive and peripherally seal the tube end.
