Abstract
Apparatus and method to facilitate heat transfer fluid flow are disclosed herein. A flexible tube having first and second ends facilitates a heat transfer fluid to flow from the first end to the second end. Ferromagnetic material encircles at least an outside portion of a length of the flexible tube, and a plurality of coil windings encircles the ferromagnetic material. The flexible tube is to be compressed to reduce an amount of flow of the heat transfer fluid from the first end to the second end by expansion of the ferromagnetic material around the flexible tube, in response to an application of a current to the plurality of coil windings.
