Patent number: 11976882Abstract: In one aspect, a heat rejection apparatus is provided including an evaporative heat exchanger and a primary fan operable to direct first ambient air into an air inlet, cause the first ambient air to interact with the evaporative heat exchanger to produce heated air, and discharge the heated air from an air outlet. The heat rejection apparatus includes a plume abatement fan operable to direct second ambient air into contact with the heated air downstream of the evaporative heat exchanger and a controller operably coupled to the primary fan and the plume abatement fan. The controller has a plume abatement mode wherein the controller operates the plume abatement fan to cause the plume abatement fan to direct the second ambient air into contact with the heated air to cool the heated air and abate plume.Type: GrantFiled: November 22, 2021Date of Patent: May 7, 2024Assignee: Baltimore Aircoil Company, Inc.Inventors: Preston Blay, Yoon K.

Patent number: 11029093Abstract: An improved heat exchange apparatus is provided with an indirect evaporative heat exchange section enclosed in a housing and a direct evaporative heat exchange section both of which are located within the same apparatus. An internal fluid stream is passed through the internal passageways of the indirect heat exchange section. An evaporative liquid is passed across the outside of the external passageways of the indirect heat exchange section to exchange heat indirectly with the internal fluid stream. The evaporative liquid that exits the indirect evaporative heat exchange section housing then passes onto and through the direct heat exchange section. The evaporative liquid exiting the direct heat exchange section is collected in a sump and then pumped upwardly to be distributed again through the indirect heat exchange section housing. The indirect heat exchange section may be comprised of a plate type heat exchanger or a circuit tube type heat exchanger located within a housing.Type: GrantFiled: March 30, 2017Date of Patent: June 8, 2021Assignee: Baltimore Aircoil Company, Inc.Inventors: Yoon K.

Patent number: 10794643Abstract: A cooling tower is provided having a heat exchange section, and a fan for moving air through the heat exchange section. A water distribution assembly provides water onto and through the heat exchange section. An air inlet section is provided through which air is drawn into the cooling tower and the heat exchange section. The air inlet section has outside edges and corners. A wall assembly is provided in the air inlet section, with the wall assembly extending from the corners of the air inlet section inwardly. The water passing through the heat exchange section enters the air inlet section, and exits to a sump beneath the air inlet section. The air inlet section is comprised of a structure having outside edges and corners, and the wall assembly is comprised of a plurality of wall panel sections. Each wall panel section has an outer edge at a corner of the air inlet section, and each wall panel section extends inwardly from the corner of the air inlet section.Type: GrantFiled: December 11, 2017Date of Patent: October 6, 2020Assignee: BALTIMORE AIRCOIL COMPANY, INC.Inventors: Yoon K. Shin, Gregory Adam Russell, Ryan J. Most, Ravindra Singh, David Andrew Aaron, Frank T. Morrison

Patent number: 10677538Abstract: A cassette for use in cassette-type heat exchanger has an inlet and an outlet, and include an upper plate and a lower plate. The upper and lower plates are sealed together around an edge area of the cassette, thereby forming a flow path within the cassette between the inlet and outlet. The plates are formed with a stamped pattern that increases the surface area of the plates as compared to a flat plate surface. The pattern includes a series of weld points whereby the upper and lower plate are welded or bonded together at a point location.Type: GrantFiled: January 5, 2018Date of Patent: June 9, 2020Assignee: Baltimore Aircoil CompanyInventor: Yoon K. Shin

Patent number: 10386135Abstract: A fill sheet arrangement in a direct heat exchange section of a cooling tower is provided. Each fill sheet includes ridges, grooves, separators, and an air inlet louver zone itself having ridges, grooves and separators, that improve the performance of the fill sheet arrangement when installed as a direct heat exchange section of a cooling tower. The air inlet louver zone improves the air flow capabilities and performance of the direct heat exchange section by limiting the evaporative liquid from leaving the fill sheet.Type: GrantFiled: March 29, 2017Date of Patent: August 20, 2019Assignee: Baltimore Aircoil Company, Inc.Inventor: Yoon K. Shin

Patent number: 4658514Abstract: A running shoe having a sole structure that includes an outsole extending from the toe to the heel and having a thickened section extending the full width of the sole structure and positioned to underlie the ball of the foot. The thickened section is appreciably thicker than the portions of the outsole that underlie the remainder of the foot. A plurality of parallel slots are cut in the thicker section across the full width of the outsole and extend from the bottom surface or tread, upwardly to just short of the top surface of the outsole to form hinges which allow it to readily flex. The slots may be partially bridged by struts which do not interfere with the hinge action at each of the slots but which provide added strength to the outsole at that region.Type: GrantFiled: October 22, 1984Date of Patent: April 21, 1987Assignee: Mercury International Trading Corp.Inventor: Yoon K.
