20090175736 | SYSTEM AND METHOD FOR PROVIDING A THERMAL TRANSPIRATION GAG PUMP USING A NANOPOROUS CERAMIC MATERIAL - A system and method for using an element made of porous ceramic materials such as zeolite to constrain the flow of gas molecules to the free molecular or transitional flow regime. A preferred embodiment of the gas pump may include the zeolite element, a heater, a cooler, passive thermal elements, and encapsulation. The zeolite element may be further comprised of multiple types of porous matrix sub-elements, which may be coated with other materials and may be connected in series or in parallel. The gas pump may further include sensors and a control mechanism that is responsive to the output of the sensors. The control mechanism may further provide the ability to turn on and off certain heaters in order to reverse the flow in the gas pump. In one embodiment, the pump may operate by utilizing waste heat from an external system to induce transpiration driven flow across the zeolite. In another embodiment, the pump may selectively drive and direct gas molecules depending on the molecular size and the interaction between the gas molecule and the zeolite element. | 07-09-2009 |

20100239436 | A THERMAL PUMP - A thermal pump for moving a sample fluid to and through an analyzer. The pump may have a lack of moving mechanical parts when pumping except for check valves. The thermal pump may have in lieu of each mechanical check valve a thermal or fluid mechanism that effectively operates as a valve without mechanical parts. The present thermal pump may be fabricated with MEMS technology. The pump may be integrated into a concentrator and/or separator of a fluid analyzer chip. | 09-23-2010 |
20120207625 | THERMALLY DRIVEN KNUDSEN PUMP - The present invention relates to thermally driven pumps. More specifically, one embodiment of the present invention relates to the use of a thermoelectric material to create a thermally driven, bi-directional pump, such as a micro pump, with no moving parts using the thermal transpiration effect (a Knudsen pump). One embodiment of the thermally driven pump of the present invention utilizes a thermoelectric material to assist with the thermal transpiration process resulting in a substantially symmetrical, bidirectional pump. A thermoelectric module is used to induce a temperature gradient across a nanoporous article having at least one nanochannel thus creating fluid flow via thermal transpiration across the nanochannel. The use of the thermoelectric module eliminates the need for a heat sink thereby making the pump substantially symmetrical and enabling bidirectional flow which is accomplished by reversing the polarity of the power supply to the thermoelectric module resulting in reversing the direction of heat transfer. | 08-16-2012 |
20120244017 | Self-Powered Pump for Heated Liquid and Heat Driven Liquid Close-Loop Automatic Circulating System Employing Same - A heat driven liquid close-loop automatic circulating system is provided. This system circulates the liquid in a close-loop by the collected heat in the loop. The system may operate without external power for the pump. The heat driven liquid close-loop automatic circulating system may employ a modified self-powered pump for heated liquid. The pump includes an airtight container for containing the heated liquid, a inlet and a outlet of the heated liquid, further more the modified self-powered pump has a breathing channel with a liquid vapour condensing and reflux structure. The heat driven liquid close-loop automatic circulating system may be a solar heated liquid close-loop automatic circulating system with a solar heat collector. | 09-27-2012 |

20150037175 | Micro-Fluidic Pump - A micro-fluidic pump comprises one or more channels having an array of resistive heaters, an inlet, outlet and a substrate as a heat sink and a means of cooling the device. The pump is operated with a fire-to-fire delay and/or a cycle-to-cycle delay to control the pumping rate and minimize heating of liquid inside the pump during its operation. | 02-05-2015 |
20150337815 | A METHOD AND APPARATUS FOR PUMPING A LIQUID - Embodiments relate to an electromagnetic, or electric, pump for pumping and/or transporting a liquid. Embodiments impart motion to a liquid, so as to stir, mix, circulate, or otherwise move the liquid. Embodiments transport water. The liquids can be conducting or non-conducting. Embodiments pump liquids in pipes. Embodiments utilize a shockwave effect, a magneto hydrodynamic effect, and/or an electrohydrodynamic effect to push the liquid. Embodiments operate with no mechanically moving parts, increasing the reliability of the pump. Embodiments of the electromagnetic (or electric) lifting, or pumping, device are thin such that the electrodes that create the pumping are installed inside the piping of the pump, reducing, or eliminating, sealing/leakage problems. Embodiments create one or more sparks, and/or filament discharges, triggered between one or more pairs of electrodes positioned such that a liquid is between the electrodes of the electrode pair, where the spark, or filament discharge, creates a plasma. | 11-26-2015 |
