Abstract
The present invention provides a method and apparatus for serial coolant flow control. In one embodiment of the present invention, two or more sets of angled rotating blades are used in series to increase the coolant pressure and flow. In this embodiment, the rotational direction of a set of blades is the reverse of the rotational direction of any set of blades next to it. In one embodiment, the angles of the blades are such that the forward velocity created by a set of blades is in the same direction as forward velocities created by other sets of blades in the system. In one embodiment, the blades of one set form a right angle with the blades of any set next to it. In one embodiment, the coolant flow controller is a fan. In another embodiment, the coolant is air. In yet another embodiment, the system being cooled is an electronic system.
