A heat sink fin that has a first substrate. The first substrate includes a first angular dimple and a first micro air channel in fluid communication with the first angular dimple. The first angular dimple includes a first surface that forms an angle relative to a first plane of the first substrate. The first angular dimple includes a first micro diameter hole in fluid communication with the first angular dimple. The heat sink fin also has a second substrate folded against the first substrate. The second substrate includes a second angular dimple and a second micro air channel in fluid communication with the second angular dimple. The second angular dimple includes a second surface that forms an angle relative to a second plane of the second substrate. The second angular dimple includes a second micro diameter hole in fluid communication with the second angular dimple.
摘要:
A process to fabricate a fin for a heat sink includes creating an array of micro diameter holes on a substrate, and then coupling the substrate to a mold. The mold includes angular dimples such that one or more of the micro diameter holes on the substrate come into contact with the angular dimples in the mold, thereby forming an angle between the micro diameter holes and a surface of the substrate. The process further includes placing the substrate onto a plate. The plate includes micro air channels such that the micro air channels are in communication with the micro diameter holes. In another embodiment, two pieces of substrate, each with micro diameter holes and embossed micro air channels are coupled together to form a fin.

摘要:
The electronic system includes an electronic device and a liquid holding section that is thermally coupled to the electronic device. The electronic system further includes an impermeable section that engages the liquid holding section. The impermeable section includes a channel and a plurality of passages that provide fluid communication between the liquid holding section and the channel. The electronic system further includes (i) a first fluid that flows through the channel in the impermeable section to facilitate heat transfer from the electronic device to the first fluid; and (ii) a second fluid that flows from the liquid holding section through the plurality of passages into the channel when the second fluid boils within the liquid holding section due to heat transfer from the electronic device to the second fluid. In some embodiments, the first and second fluids are different types of substances.

摘要:
A gas sensor is provided for detecting one or more gases in a gas sample. The gas sensor includes a substrate, a solid electrolyte layer including lanthanum oxide for sensing carbon dioxide, a heating element thermally coupled to the solid electrolyte layer, and a controller coupled to the heating element and the solid electrolyte layer. The controller heats the heating element so that the solid electrolyte layer reaches an operating. Methods of sensing carbon dioxide and humidity are also disclosed.
摘要:
A system for testing and calibrating gas sensors with gas stored in a strip of packets. The strip may be fed into a chamber having a defined volume of air. A packet may be punctured with a mechanism to release one or more gases into the volume of air to result in an air-gas mixture. New air may be moved into the chamber to push the mixture out of the chamber to a sensor for testing and/or calibration. Then another packet may be punctured to release one or more gases into the volume of new air in the chamber for another air-gas mixture. This mixture may be moved out of the chamber, in the same manner as the previous mixture, to another sensor for testing and/or calibration. This procedure may be repeated with additional packets on the strip.
摘要:
A nanowire super-capacitor electrode for storing electrical energy. The electrode is formed by anodizing a porous membrane having a uniform pore size and diameter, depositing a metal layer on the membrane back, electroplate metal through the pores of the membrane, dissolving the porous membrane. The formed nanowire electrode is placed in an electrolyte to integrate said nanowire into an electrolytic capacitor.
