Abstract
A microcooler includes a substrate with a first and second microchannel and an orifice disposed between, in fluid communication with both. A pair of electrodes is in a vicinity of the orifice. An electrical resistive heating material is in electrical communication with the electrodes and is in thermal contact with a fluid in the vicinity of the orifice. A system includes the microcooler and a voltage source to apply a voltage across the electrodes, which induces sufficient heating in the heating material to disassociate something clogging the orifice, without significant damage to the heating material. Some systems include a sensor configured to detect an effect of clogging at the orifice. A processor is configured to receive sensor output from the sensor, and if there is an effect of clogging, then cause the voltage to be applied across the electrodes.
