Abstract: Cooling facilities for an electronic component provide a cooling device that occupies a small volume, requires only a relatively low operating voltage, and operates in any orientation. The cooling facility consists of a body defining a coolant passage including an inlet and an outlet, a pumping chamber with a variable volume changeable from a greater volume to a lesser volume in fluid communication with the inlet and the outlet, and a flow restriction facility in fluid communication with the inlet and the outlet. The flow restriction facility provides limited flow resistance to coolant flow in a first direction from the inlet to the outlet and provides increased resistance to coolant flow in the opposite direction from the outlet to the inlet. Therefore, repeated reciprocation of the pumping chamber between a greater volume and a lesser volume generates a net fluid flow from the inlet to the outlet.
