US Patent:

61092347, Aug 29, 2000

Filed:

Oct 16, 1998

Appl. No.:

9/174237

Inventors:

James Kirkland Vallance - Northville MI
Robert William Page - South Lyon MI
Lyn Louis Vandenabeele - St. Clair Shores MI
David Hollis Barber - Allen Park MI

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

F02B 3108

US Classification:

123308

Abstract:

An internal combustion engine cylinder head includes a pent roof (15) closing off a top of an engine cylinder (14) and first and second inclined surfaces (15a, 15b) intersecting an apex region (15c) of the pent roof. First and second air intake ports (20, 22) are formed in the pent roof surfaces and about respective first and second spiral axes (S1, S2) having respective radii (R1, R2, etc. ) that change in magnitude and elevation as each air intake port approaches respective port entrances (20a, 22a) to the cylinder in a manner to provide air flows with in-cylinder air swirl in the same direction about the longitudinal axis of the cylinder.

International Classification:

F28D 1/053
F25B 39/02

Abstract:

A heat exchanger includes a shell, refrigerant distributor, tube bundle, and a first baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor. The first baffle extends from a first lateral side of the shell. The first baffle is vertically disposed 5% to 40% of an overall height of the shell above a bottom edge of the shell, and extends laterally inwardly from the first lateral side by a distance not more than 20% of a width of the shell.

International Classification:

F28D 1/053
F25B 39/02
F28F 9/02

Abstract:

A heat exchanger includes a shell, refrigerant distributor, tube bundle, and first upper baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor so that the liquid refrigerant discharged from the refrigerant distributor is supplied to the tube bundle. The first upper baffle is vertically disposed at a top of the tube bundle. The first upper baffle extends laterally outwardly from the tube bundle toward a first lateral side of the shell.
