Abstract: An insert snaps into position in a manifold of a fluid device to perform a baffling function. The insert includes a cradle having a base portion and opposed spring fingers for retaining the insert in position. The base portion can be completely closed to prevent flow through the insert, or have a spring flapper valve or bimetallic flapper valve to permit partial or full flow through the insert under predetermined conditions.

Abstract: A method for forming heat exchanger plates (10) comprises formation of a fluid flow channel (28) along the edges (22) of a sheet metal strip or blank, and formation of a pair of raised end bosses. The raised end bosses (32) are elongated in the longitudinal dimension and are formed within the final width dimension of the plate so as to avoid the need for trimming of excess material along the edges of the plate. The method generates less scrap than prior art processes using progressive stamping, and also permits variation of the plate lengths.

Abstract: A core for a charge air cooler comprises inner and outer concentric tubes providing an axially extending annular passageway for flow of a fluid, preferably a liquid coolant. A first inlet and a first outlet are provided at the ends of the axial annular passageway. Arranged on an outer surface of the outer tube is at least one circumferential fluid flow passageway for flow of a fluid, preferably air. Each circumferential flow passageway is provided with a corrugated strip fin comprising a plurality of rows of corrugations. The core is combined with an outer housing to form a heat exchanger. The housing is provided with an inlet and an outlet for the fluid flowing through the circumferential flow passageways. Other embodiments are disclosed in which the heat exchanger is adapted for use with three fluids and in which additional cooling capacity is provided by the provision of coolant passageways in the housing.

Abstract: A heat exchanger and mounting bracket therefor where the heat exchanger is formed of stacked plate pairs or tubes having longitudinal peripheral edge portions joined together. The mounting bracket has spaced-apart, C-shaped clips attached to the peripheral edge portions of different plate pairs and mounting portions attached to the C-shaped clips and extending outwardly from the plate pairs.

Abstract: A mechanical connection for tubular members has a male tubular member with a distal end portion containing an O-ring. A female tubular member fits over the male member in sealing engagement with the O-ring, so that the O-ring is only radially compressed. The female member is crimped or compressed on to the male member, such that engaging ribs and grooves in the male and female members lock the members together against axial relative movement. The crimping operation does not affect the O-ring seal because the ribs and grooves are spaced axially from the O-ring seal.
