Plate heat exchanger with a hybrid flow control device

A method for controlling a thermal management system, comprising:

• providing a thermal management system including a heat exchanger fluidly connected to a fluid circuit for a fluid, wherein the heat exchanger comprises a flow control device is disposed in an inlet manifold of the heat exchanger fluidly connected to the fluid circuit, and wherein the flow control device includes a housing, a first movable member disposed in the housing, and a second movable member disposed in the housing;
• positioning the first movable member of the flow control device to regulate a flow of the fluid through a bypass flow channel within the heat exchanger based on a temperature of the fluid entering into the heat exchanger;
• and
• variably positioning the second movable member of the flow control device to regulate the flow of the fluid through a plurality of thermal exchange flow channels within the heat exchanger based on an inflow momentum of the fluid entering into the heat exchanger.
