An attenuation device for a vehicle is provided, including a housing having a chamber formed therein. The housing is coupled to and in fluid communication with an air-conditioning circuit of the vehicle. A dampening member is disposed within the chamber of the housing. The dampening member includes a partition plate having at least one pipe disposed therein. The dampening member is configured to attenuate acoustic energy produced by a fluid of the air-conditioning circuit.

Universal attenuation device for air-conditioning circuit

A line fitting employs blocks secured together with a stud and a nut and having gaskets or seals which militate against permeation of CO when subjected to high pressures and high temperatures, the seals are also resistant to decompression damage.

A method for making a plate-tube heat exchanger 10 is disclosed. The method includes the steps of forming a generally planar plate blank 36 from a deformable sheet of material, forming an aperture 38 at one end of the plate blank and forming a plurality of generally elongate bead preforms 40 in a predetermined configuration by drawing the material from the bottom surface of the plate blank towards the top surface. Next, a plurality of individual beads 34 are formed from each of the plurality of bead preforms by reverse drawing the bead preforms in a direction from the top surface of the plate towards the bottom surface of the plate. The method of the present invention concludes by forming the finish edges 46 of the plate.

A plate is disclosed for use in a plate-fin heat exchanger, comprising a generally planar elongated member having a longitudinal rib disposed along the longitudinal length of the member. The plate further includes a first plurality of beads having a height greater than the height of the rib as well as a second plurality of beads having a height approximately equal to the height of the longitudinal rib. The beads are arranged generally in rows having a planar space of predetermined longitudinal length therebetween into which an adjoining row of beads is placed when a pair of identical plates are laminated together in a face-to-face relationship and forming a heat exchanger. A heat exchanger comprising a plurality of stacked plates generally as described above is also disclosed.
