Method and apparatus for serial coolant flow control

A system for cooling at least one electronic device comprising:

• at least one electronic device;
• an enclosure including an interior coolant region, an exterior coolant region, a coolant intake and a coolant exhaust, said at least one electronic device being located inside said enclosure and having at least one exterior surface exposed to said interior coolant region;
• a coolant;
• and
• a serial coolant flow controller located inside said enclosure, said serial coolant flow controller comprising:
• a first plurality of blades located substantially adjacent to said coolant intake and configured to rotate in a first rotational direction wherein said first plurality of blades are configured at a first angle to a rotational axis and are operable to propel at least a portion of said coolant into said enclosure via said coolant intake;
• and
• a second plurality of blades located substantially adjacent to, and in series with, said first plurality of blades and configured to rotate in a second rotational direction wherein said second plurality of blades are configured at a second angle to said rotational axis and are operable to propel said at least a portion of said coolant into said interior coolant region, said at least a portion of said coolant being propelled out of said enclosure via said coolant exhaust when the pressure of said interior coolant region exceeds the pressure of said exterior coolant region, wherein said first angle is different from said second angle.

A computer program product comprising:

• a computer usable medium having computer readable program code embodied therein configured for serial coolant flow control, comprising:
• computer readable code configured to cause a computer to rotate a first plurality of blades in a first rotational direction wherein said first plurality of blades are configured at a first angle to a rotational axis wherein said first plurality of blades are operable to transfer a first amount of energy to the coolant to propel said coolant and provide a coolant pressure at a first pressure level and a coolant flow at a first coolant flow rate, and thereby propel a coolant in a forward direction along said rotational axis and a first swirl direction tangential to said rotational axis;
• and
• computer readable code configured to cause a computer to rotate a second plurality of blades in a second rotational direction wherein said second plurality of blades are configured at a second angle to said rotational axis wherein said second plurality of blades are operable to transfer a second amount of energy to said coolant to propel said coolant and increase said coolant pressure from said first pressure level to a second pressure level and increase said coolant flow from said first coolant flow rate to a second coolant flow rate, and thereby propel said coolant in said forward direction along said rotational axis and a second swirl direction tangential to said rotational axis wherein said first plurality of blades is in series with said second plurality of blades.
