Abstract: A reducer housing and an electric drive assembly are disclosed. A liquid cooled heat dissipation structure is provided at a bottom of the reducer housing and/or on a side wall thereof through which lubricating oil flows. The heat dissipation structure includes a coolant tank and a cover plate that seals the coolant tank. Two ends of the coolant tank are respectively provided with a liquid inlet and a liquid outlet. Convex structures and concave structures are alternately provided on the bottom of coolant tank so that inner and outer sides of the bottom of the coolant tank are in a wavy shape to increase a contact area between the coolant tank and the lubricating oil inside the reducer housing.
