Patent number: 6764279Abstract: Improved efficiency is obtained in a rotary machine having a rotary shaft (18) mounting a compressor wheel (20) that discharges into a heat exchanger (36) having a core (82) with a central opening (42) in surrounding relation to the shaft (18). The heat exchanger (36) includes a coolant tank (90) on one side of the core (82) and in fluid communication with the same which serves as one boundary of radially extending space (68) through which a gas is discharged by a compressor wheel (20). A deswirling vane structure (80) causes gas discharged by the compressor wheel (22) to move radially outward within the space (68) and is formed of a material of good thermal conductivity and thermally bridged to the tank (90) to conduct heat thereto to be rejected to coolant in the tank.Type: GrantFiled: September 27, 2002Date of Patent: July 20, 2004Assignee: Modine Manufacturing CompanyInventor: Steven P.
