Patent number: 11644245Abstract: An improved indirect heat exchanger including a plurality of coil circuits, with each coil circuit comprised of an indirect heat exchange section tube run or plate. Each tube run or plate has at least one change in its geometric shape or may have a progressive change in its geometric shape proceeding from the inlet to the outlet of the circuit. The change in geometric shape along the circuit length allows simultaneously balancing of the external airflow, internal heat transfer coefficients, internal fluid side pressure drop, cross sectional area and heat transfer surface area to optimize heat transfer.Type: GrantFiled: April 24, 2020Date of Patent: May 9, 2023Assignee: Baltimore Aircoil Company, Inc.Inventors: Andrew Beaver, David Andrew Aaron, Yohann Lilian Rousselet

Patent number: 11092394Abstract: An indirect heat exchanger has two airflow paths and an airflow generator to draw air through the airflow paths. A fluid conduit passes through the heat exchanger such that a cooling region is positioned within each of the flow paths. A dispenser is positioned to dispense evaporative liquid on one of the cooling regions. The dispenser operates in a wet mode and a dry mode. A controller regulates airflow through the first flow path and the second flow path, and also controls the operation of the dispenser. In this way, the controller may operate the airflow paths independently such that the airflow through a flow path operating in the dry mode is greater than that of the flow path operating in the wet mode.Type: GrantFiled: March 13, 2020Date of Patent: August 17, 2021Assignee: BALTIMORE AIRCOIL COMPANY, INC.Inventors: Preston Blay, Ravindra Singh, Frank T. Morrison, Andrew Beaver, David Andrew Aaron

Patent number: 4004326Abstract: A protector for protecting cable which is connected to a tubing string in a well. The protector is generally cylindrical having a bore adapted to be secured to the tubing of the string and is constructed in two pieces for ease of installation. A longitudinally extending slot is provided which is so dimensioned as to fully receive the cable. The protectors are spaced along the tubing string which may extend for great distances. The protectors may be of elastomeric material and may be eccentric with the cable receiving slot positioned in the thickest section. Lips overlying the slot may be provided as a measure to restrain the cable in the slot, to further protect cable from burrs or other protuberances and to provide wear points on the protector further from the cable.Type: GrantFiled: December 22, 1975Date of Patent: January 25, 1977Assignee: Borg-Warner CorporationInventor: John Andrew Beavers
