Abstract
An embodiment of the invention is directed to coolant flow control apparatus, in association with a liquid flow through heat exchanger situated to cool one or more electronic or other device. The apparatus comprises a first input channel for carrying liquid coolant to a first input of the heat exchanger, and further comprises a flow control device positioned along a flow path that includes the first input channel. The flow control device is provided with a gating element supported for selected movement across the flow path, in order to selectively vary the amount of coolant moving through the flow path. The apparatus further include an actuator located in the flow control device that comprises a metal component which is directly tied to the gating element, wherein the metal component changes its shape in response to specified changes in coolant temperature, and a given change in the shape of the metal component acts to selectively move the gating element with respect to the flow path.
