Abstract
An electric drive unit includes an electric motor and a housing that houses the electric motor. The housing includes a heat exchanging wall portion that includes an inner surface that defines a fluid jacket cavity for conveying a first fluid and an outer surface that is opposite the inner surface and that defines a fluid chamber for conveying a second fluid. The heat is transferred between the first and second fluids through the heat exchanging wall portion.
Claims20
An electric drive unit, comprising:
- an electric motor;
- and
- a housing that houses the electric motor and includes a heat exchanging wall portion that includes an inner surface that defines a fluid jacket cavity for conveying a first fluid and an outer surface that is opposite the inner surface and that defines a fluid chamber for conveying a second fluid, wherein heat is transferred between the first and second fluids through the heat exchanging wall portion.
An electric drive unit, comprising:
- a body having a surface that defines a fluid chamber, wherein the surface forms a base and a plurality of protrusions extending outward from the base within the fluid chamber, the plurality of protrusions comprising:
- a first protrusion having a height that the first protrusion extends outward from the base to a distal end of the first protrusion, a width, and a length that is greater than the width of the first protrusion such that the first protrusion is elongated in the lengthwise direction of the first protrusion;
- and
- a second protrusion having a height that the second protrusion extends outward from the base to a distal end of the second protrusion, a width, and a length that is greater than the width of the second protrusion such that the second protrusion is elongated in the lengthwise direction of the second protrusion, wherein the first and second protrusions are oriented such that an angular difference between the lengthwise directions of the first and second protrusions is greater than an angular difference between the heightwise directions of the first and second protrusions.
An electric drive unit, comprising:
- an electric motor;
- a housing that houses the electric motor and includes an outer surface that forms a base and a plurality of protrusions that extend radially outboard from the base;
- and
- a cover coupled to the housing and having a plurality of protrusions that are aligned with the plurality of protrusions of the outer surface of the housing, wherein the outer surface of the housing and the cover cooperate to define a fluid chamber for conveying fluid.
