International Classification:

H05K 7/20
H01L 23/34
H01L 23/367
F28D 15/00

US Classification:

361702, 36167953, 36167954, 361709, 361710, 361711, 361718, 16510433, 257713, 257714

Abstract:

An apparatus includes a plurality of islands each carrying multiple cantilevers. The apparatus also includes a fluidic network having a plurality of channels separating the islands. The channels are configured to provide fluid to the islands, and the fluid at least partially fills spaces between the cantilevers and the islands. Heat from the islands vaporizes the fluid filling the spaces between the cantilevers and the islands to transfer the heat away from the islands while driving the cantilevers into oscillation. The apparatus may also include a casing configured to surround the islands and the fluidic network to create a vapor chamber, where the vapor chamber is configured to retain the vaporized fluid. The islands and the fluidic network could be formed in a single substrate, or the islands could be separate and attached together by a binder located within the channels of the fluidic network.

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

G01F 1/00
G01F 1/84

US Classification:

702 50, 73861355

Abstract:

A method includes creating Coriolis-based deflection in at least one oscillating flow tube of a flow meter, which is caused by material flowing through the at least one flow tube. The method also includes determining a deflection amplitude and deflection period using interferometric measurements. The method further includes determining a characteristic of the material using the amplitude and period and transmitting the characteristic. A laser interferometer could include a photo-detector. The deflection period could be based on variations in a period of fringes in the photo-detector's output. The deflection amplitude could be based on a number of fringes during the deflection period. A resonant frequency of the at least one flow tube can be determined using the deflection period, and a density of the material can be determined using the resonant frequency. The characteristic of the material could include a mass flow rate or a volumetric flow rate of the material.

International Classification:

F28F 7/00
H05K 7/20

US Classification:

165 804, 16510421, 361699

Abstract:

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.
