Abstract
An electronics housing for power electronics of an electrified powertrain, including a receiving space for components of power electronics, an inlet into the receiving space for a temperature control fluid, an outlet into the receiving space for a temperature control fluid, and an electromagnetic compatibility (EMC) shielding element for protecting the power electronics and/or, conversely, surrounding components from possible electromagnetic interferences. The EMC shielding element also includes a particulate filter for the temperature control fluid flowing in via the inlet and flowing out via the outlet.
Claims20
An electronics housing for power electronics of an electrified powertrain, comprising:
- a receiving space for components of the power electronics;
- an inlet into the receiving space configured to permit a temperature control fluid to flow into the receiving space;
- an outlet from the receiving space configured to permit the temperature control fluid to flow out of the receiving space;
- and
- an electromagnetic compatibility (EMC) shielding element arranged in the receiving space and configured to protect the power electronics from electromagnetic interferences,
- wherein the receiving space at least partially defines a path for the temperature control fluid to flow from the inlet to the outlet, and
- wherein the EMC shielding element comprises an electrically conductive material having a structure configured as a particulate filter, which is arranged in the path.
A motor vehicle, comprising:
- at least one high-voltage operated electrical traction machine;
- power electronics for the high-voltage operated electrical traction machine;
- and
- at least one propulsion wheel, which can be driven by the high-voltage operated electrical traction machine to propel the motor vehicle,
- wherein the power electronics are shielded and enclosed with temperature control in an electronics housing for the power electronics of an electrified powertrain, the electronics housing comprising:
- a receiving space for components of the power electronics;
- an inlet into the receiving space for a temperature control fluid;
- an outlet into the receiving space for the temperature control fluid;
- and
- an electromagnetic compatibility (EMC) shielding element for protecting the power electronics and/or, conversely, surrounding the components from possible electromagnetic interferences,
- wherein the EMC shielding element also comprises a particulate filter arranged in a path of the temperature control fluid flowing in via the inlet and flowing out via the outlet.
