Low-Profile Heat-Spreading Liquid Chamber Using Boiling

View page
US Patent:
20130020053, Jan 24, 2013
Filed:
Jun 6, 2012
Appl. No.:
13/489697
Inventors:
Seung Mun You - Arlington TX, US
Joo Han Kim - Arlington TX, US
Sang M. Kwark - Grand Prairie TX, US
Jesse Jaejin Kim - Sunnyvale CA, US
International Classification:
F28D 15/02
F28F 13/18
US Classification:
16510421, 16510429, 165133
Abstract:
Systems and fabrication methods are disclosed for a heat spreader to cool a device. The heat spreader has first and second opposing proximal surfaces defining a chamber having a liquid therein; and one or more structures mounted in the chamber to induce a liquid flow pattern during a boiling of the liquid to distribute heat.

Seung Mun You - Arlington TX, US
Joo Han Kim - Arlington TX, US
Sang M. Kwark - Grand Prairie TX, US
Jesse Jaejin Kim - Sunnyvale CA, US
International Classification:
H05K 7/20
US Classification:
16510421, 361700
Abstract:

The heat spreader has first and second opposing proximal surfaces defining a chamber having a liquid therein; and one or more structures mounted in the chamber to induce a liquid flow pattern during a boiling of the liquid to distribute heat.

System And Method For Cryogenic Vaporization Using Circulating Cooling Loop

View page
US Patent:
20220290815, Sep 15, 2022
Filed:
Nov 2, 2021
Appl. No.:
17/516984
Inventors:
Hanfei Tuo - East Amherst NY, US
Chao Liang - East Amherst NY, US
Maulik R. Shelat - Williamsville NY, US
Sang Muk Kwark - Holly Springs NC, US
Seth A. Potratz - Grand Island NY, US
International Classification:
F17C 9/02
Abstract:
A cryogenic vaporization system and method are provided. A first heat exchanger heats a liquid cryogen via indirect heat exchange to output a cryogenic vapor at a first temperature. A second heat exchanger receives the cryogenic vapor at the first temperature. The second heat exchanger heats the cryogenic vapor via indirect heat exchange to a second temperature. The cryogenic vapor at the second temperature is recirculated to the first heat exchanger to heat the liquid cryogen and cool the recirculated cryogenic vapor to a third temperature. A third heat exchanger receives the cryogenic vapor at the third temperature. The third heat exchanger heats the cryogenic vapor to a fourth temperature. The third heat exchanger outputs the cryogenic vapor at the fourth temperature.

Air Separation Unit Heat Exchanger With Porous Boiling Surface Coatings

View page
US Patent:
20180299035, Oct 18, 2018
Filed:
Jun 21, 2018
Appl. No.:
16/014642
Inventors:
Zigui Lu - East Amherst NY, US
Sang Muk Kwark - Holly Springs NC, US
Joseph M. Corpus - Avon IN, US
Jonathan A. Lane - Snyder NY, US
David P. Potempa - Boston NY, US
Maulik R. Shelat - Williamsville NY, US
International Classification:
F16L 9/02
C09D 131/02
C09D 5/26
C08J 9/00
C09D 101/28
Abstract:
A porous metallic coating is provided. The coating is characterized by a combination of optimized properties that improve coating performance, as measured by heat transfer efficiency. The porous coating has optimal ranges for properties such as porosity, particle size and thickness, and has particular applicability in boiling heat transfer applications as part of an air separations unit. The porous coatings are derived from slurry-based formulations that include a mixture of metallic particles, a binder and a solvent.

US Patent:
20170108296, Apr 20, 2017
Filed:
Oct 15, 2015
Appl. No.:
14/884171
Inventors:
SANG MUK KWARK - WILLIAMSVILLE NY, US
ZIGUI LU - EAST AMHERST NY, US
DAVID P. POTEMPA - BOSTON NY, US
MAULIK R. SHELAT - WILLIAMSVILLE NY, US
International Classification:
F28F 13/18
C09K 5/14
B05D 7/22
Abstract:
A method for creating a coating onto a conduit is provided. The method includes rotating the conduit while injecting a controlled amount of slurry onto the surface of an inner diameter of the conduit through a nozzle that is retracted from out of the conduit at a controlled speed. The method offers improved reproducibility and repeatability of coating properties in comparison to conventional coating methods.

Condenser-Reboiler System And Method

View page
US Patent:
20170023297, Jan 26, 2017
Filed:
Oct 5, 2016
Appl. No.:
15/285545
Inventors:
Maulik R. Shelat - Williamsville NY, US
Vijayaraghavan S. Chakravarthy - Williamsville NY, US
Sang Muk Kwark - Williamsville NY, US
International Classification:
F25J 5/00
F25J 3/04
Abstract:
A system and method for the concurrent condensation of a nitrogen-rich vapor and vaporization of an oxygen-rich liquid in a distillation column based air separation unit is provided. The disclosed system includes a condenser-reboiler heat exchanger located between a lower pressure column and a higher pressure column and configured to condense a nitrogen-rich vapor from the higher pressure column and partially vaporize an oxygen-rich liquid from the lower pressure column. Within the condenser-reboiler heat exchanger, the nitrogen-rich vapor flows in an upward direction such that any non-condensables present in the nitrogen-rich vapor will accumulate proximate the upper portion or top of the condenser-reboiler modules where they can be easily removed through venting.
