Abstract: A battery cooling plate includes at least one planar heat transfer surface that is bounded by four edges. A coolant inlet port and a coolant outlet port are both arranged along a first one of the edges, and a coolant flow path extends through the battery cooling plate adjacent to the at least one planar heat transfer surface between the coolant inlet port and the coolant outlet port. The coolant flow path includes a first portion that extends along the entire length of a second, third, and fourth edge of the at least one planar heat transfer surface. The coolant flow path further includes a second portion that is arranged downstream of the first portion. The second portion of the coolant flow path is separated from the second, third, and fourth edges of the planar heat transfer surface by the first portion of the coolant flow path.

Abstract: A header for a heat exchanger includes a first and a second cylindrical portion. The first cylindrical portion has a first diameter, and extends over a first length portion of the header. The second cylindrical portion has a second diameter that is smaller than the first diameter, and extends over a second length portion of the header. Tube receiving slots are arranged along the first length portion. An end cap is received into an open end of the first cylindrical portion, and is joined thereto to seal a first end of the header. An open end of the second cylindrical portion is arranged at a second end of the header opposite the first end to allow for fluid flow into or out of the header. A circumferential bead is located between the first and second cylindrical portions, and extends radially outward of the first cylindrical portion.

Abstract: A gear casing heat exchanger has a mounting flange separating the heat exchanger into a first side and a second side. A manifold section is on the first side, and includes an inlet manifold and an outlet manifold. A heat exchange section is on the second side, and extends from the mounting flange in a lengthwise direction. A sealing perimeter is on the second side, and the heat exchange section is entirely contained within a projection of the sealing perimeter in the lengthwise direction. The heat exchange section of the heat exchanger can be inserted through an aperture of a gear casing to provide a cooled gear assembly.
