Aluminum Motor Housing
The invention relates to an aluminum alloy motor housing and a manufacturing method thereof, relating to a motor housing, and particularly applicable to a liquid cooling aluminum alloy motor housing of a new energy automobile. The utility model is characterized in that the structure of the shell comprises a tubular barrel body which is extruded by an aluminum alloy and is provided with a cooling liquid circulation passage inside, an annular sealing cover which covers the end of the tubular barrel body, and a tubular barrel of a cooling liquid circulation passageway. The outer wall is open with coolant inlets and outlets. The tubular body of the motor casing is divided into a plurality of tile-like separated single parts in the axial direction, which are respectively formed by extrusion; then, the extruded single-piece pieces are separately welded to form a tubular body. The structure, process is simple, safety is good, high-power motors can be manufactured, high production efficiency, and good cooling performance.
