A vapor chamber device having a first vapor core configured to passively spread heat from a localized first input area to a relatively larger first output area adjacent to and in thermal contact with a heat output side of the vapor chamber device, and a second vapor core configured to passively spread heat from a localized second input area adjacent to and in thermal contact with a heat input side of the vapor chamber device to a relatively larger second output area in thermal contact with the first input area of the first vapor core. The second vapor core is configured to attenuate high heat flux hotspots on the first input area before the heat fluxes thereof pass through the second output area of the second vapor core to the first input area of the first vapor core.

Vapor chamber devices and methods of dissipating heat therewith

The present disclosure relates to a novel absorbance-based colorimetric device system, and to methods of using the novel absorbance-based colorimetric device system.

Absorbance-based colorimetric device system

Systems and methods that utilize enhanced boiling surfaces to promote the efficiency of boiling. Such a system has a surface that is hydrophobic and exhibits a sufficiently low receding contact angle to a liquid such that vapor spreading during bubble growth and premature transition to film boiling is mitigated.

Boiling processes and systems therefor having hydrophobic boiling surfaces

Methods and apparatuses for detection of gas bubbles in a microchannel configured for a conductive fluid to flow therethrough. The methods and apparatuses utilize a plate and at least two aligned electrodes embedded within the plate. The plate is configured to be located over the microchannel such that the at least two aligned electrodes are located along a length of the microchannel in the flow direction. Impedance is measured between the electrodes, and the percentage of gas within the fluid flowing through the microchannel is measured based on the measured impedance between the electrodes.
