SHEAR DRIVEN MICRO-FLUIDIC PUMP
First Claim
1. An apparatus to pump a fluid, comprising:
- a housing extending along a length defining an elongate interior;
an actuator in the housing, conforming to the elongate interior, the actuator including a plurality of lumens, each having a length extending substantially parallel to the elongate interior, each from around 10 to 200 micrometers across; and
an actuator configured to oscillate the actuator in the actuator housing along the length of the elongate interior with a rate differential between movement in a first direction versus movement in a second direction opposite the first direction to pump the fluid.

27. A method for heat exchange between a heat source and a heat exchanger, comprising:
-
affixing the heat exchanger to the heat source, with the heat exchanger thermally communicative with the heat source; pumping a fluid through the heat exchanger, at a determined flow rate and fluid pressure, by oscillating an actuator in a pump housing extending along a length defining an elongate interior, the actuator conforming to the elongate interior, the actuator including a plurality of lumens, each having a length extending substantially parallel to the elongate interior, each from around 20 to 200 micrometers across, wherein an oscillation takes place with a rate differential between movement in a first direction versus movement in a second direction opposite the first direction; and exchanging heat between the heat exchanger and the heat source. - View Dependent Claims (28, 29, 30, 31, 32, 33)

34. A heat exchange system for heat exchange with an integrated circuit, the system comprising:
-
a circulation loop to contain a fluid; a heat emission portion in fluid communication with the circulation loop and configured to exchange heat with a cold source; at least one heat absorption portion in fluid communication with the circulation loop and configured to exchange heat with the integrated circuit; and a pump to pump a fluid through the circulation loop, the pump including; a housing extending along a length defining an elongate interior; an actuator in the housing, conforming to the elongate interior, the actuator including a plurality of lumens, each having a length extending substantially parallel to the elongate interior, each from around 20 to 200 micrometers across; and an actuator configured to oscillate the actuator in the actuator housing along the length of the elongate interior with a rate differential between movement in a first direction versus movement in a second direction opposite the first direction to pump the fluid. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
