Abstract
A machine cooling circuit of an electric machine of a motor vehicle, including a coolant adapted to flow through the machine cooling circuit and a compensating reservoir, which separates air included in the coolant. The electric machine is a directly cooled electric machine, which is accommodated in the machine cooling circuit such that the coolant flows through it.
Claims16
A machine cooling circuit of an electric machine of a motor vehicle, comprising:
- a coolant adapted to flow through the machine cooling circuit;
- a compensating reservoir that is force-loaded or pressure-loaded such that the force-loading or pressure-loading separates air entrained in the coolant from the coolant;
- and
- a conveyance means formed in the machine cooling circuit arranged downstream of a filter element formed in the machine cooling circuit relative to a heat exchanger and upstream of the heat exchanger formed in the machine cooling circuit relative to the filter element,
- wherein the electric machine is a directly cooled electric machine, which is accommodated in the machine cooling circuit such that the coolant flows through the electric machine,
- wherein a microbubble separator is arranged in the machine cooling circuit, and
- wherein the conveyance means of the machine cooling circuit is configured as a tandem pump with a second conveyance means of a transmission cooling circuit.
