An electric machine includes an enclosure housing multiple electrical components including a rotor assembly and a stator assembly, a heat exchanger coupled to the enclosure for cooling of the electrical components by creating an internal fluid flow circuit between the heat exchanger and the electrical components, wherein the heat exchanger comprises multiple cooling fluid inlets and a common cooling fluid outlet, wherein the multiple cooling fluid inlets are arranged so that cooling fluid enters the heat exchanger at different sections, and wherein the cooling fluid exits the heat exchanger through the common cooling fluid outlet.
