A housing for cooling an electric motor in an electric vehicle includes a tubular frame with a first end and a second end, where the first end has first openings, the second end has second openings, and the tubular frame has first channels encased in the tubular frame running between the first openings and the second openings. The housing also includes a first cover that mates with the first end of the tubular frame and includes third openings positioned to mate with the first openings, and second channels that connect the first openings together. A second cover mates with the second end of the tubular frame and has fourth openings positioned to mate with the second openings of the tubular frame, and third channels that connect the second plurality of openings together. The first channels, the second channels, and the third channels form pathways through which coolant can flow.
