Benefits of technology

[0006]The present invention relates to a change in the design of an ACC which will result in substantially less field welding. This will make ACCs cheaper to erect and much more attractive to purchase.
[0018]According to the present invention, significant cost savings are presented at the assembly site, and while some work transferred to the manufacturing facility / factory / shop, factory labor is much less costly than assembly labor, and will not add significantly to the cost of fabricating an HEC.

Problems solved by technology

The current ACC design requires a significant amount of field welding.
Companies that purchase ACCs, as well as the companies that erect them for purchasers, face very high costs to install them, and one of the contributory factors to the high installation cost is the amount of labor, man hours, and equipment costs it takes to do the field welding.
Field welding can be very expensive when compared to the cost of shop welding.

first embodiment

[0045]FIGS. 6A through 6D, 7 and 8 show the invention in which the closure plate 8 is replaced with an angle 16, that is, an L-shaped piece of steel. During the factory manufacture process, angle 16 is shop welded to the tube sheets 12a of one half of the heat exchange coils. According to a preferred embodiment, the end of tube sheets 12a may be angled or beveled to fit flush or nearly flush against a face of the angle 16. The preferred locations of the shop welds are shown in FIGS. 6A and 6B.

[0046]For assembly of an ACC according to this first embodiment of the invention, one half of the primary heat exchanger coils that are shipped to the assembly location include the shop welded angle, and the other one half of the primary heat exchanger coils have a generally standard configuration. During assembly of the heat exchanger A-frame 2 at the assembly location, one modified heat exchanger coil bearing the shop welded angle is positioned opposite a generally standard configuration heat...

second embodiment

[0047]FIGS. 9A through 9C show the invention in which one half of the primary heat exchanger coils are fitted with an extended and bent tube sheet 18, and the other half of the primary heat exchanger coils may have the standard configuration. The length of the extension and angle of the bend is configured to generally allow for a flush connection between the top face of the bend and the edge of the tube sheet of the heat exchanger coil to which it will be welded during site assembly.

[0048]For assembly of an ACC according to this embodiment of the invention, one half of the primary heat exchanger coils that are shipped to the assembly location include the extended and bent tube sheet, and the other one half of the primary heat exchanger coils have a generally standard configuration. During assembly of the heat exchanger A-frame 2 at the assembly location, one modified heat exchanger coil bearing the extended and bent tube sheet 18 is positioned opposite a generally standard configura...

third embodiment

[0049]FIGS. 10A through 10C show the invention in which the closure plate 8 is replaced with an inverted V-shaped length of steel 20 that is shop welded at the factory to the tube sheets 12a of one half of the primary heat exchange coils. According to a preferred embodiment, the end of tube sheets 12a need not be angled or beveled to fit flush or nearly flush against a face of the V-shaped length of steel 20.

[0050]For assembly of an ACC according to this third embodiment of the invention, one half of the primary heat exchanger coils that are shipped to the assembly location include the shop welded inverted V-shaped length of steel 20, and the other one half of the primary heat exchanger coils have a generally standard configuration. During assembly of the heat exchanger A-frame 2 at the assembly location, one modified heat exchanger coil bearing the shop welded V-shaped length of steel 20 is positioned opposite a generally standard configuration heat exchanger coil, and the inner ed...

Abstract

An air cooled condenser, and methods of manufacturing and field assembly of air cooled condensers in which one half of the primary heat exchanger coils are shop fitted with a length of steel configured to quickly and easily mate, during field assembly, with an opposing primary heat exchanger coil of standard configuration, thereby reducing material, shipping, and handling costs, improving positioning and orientation of HECs during assembly, and reducing the requirement for expensive field welding.

Description

FIELD OF THE INVENTION[0001]The present invention relates to air-cooled condensing systems and more particularly to an air cooled condensing system that maintains thermodynamic efficiency but is much simpler and cheaper in physical installation than the current state of the art air cooled condensing systems.BACKGROUND OF THE INVENTION[0002]Current state of the art air cooled condensing systems use flat two-dimensional tube sheets. The elevation of tube sheets in an A-framed air cooled condenser (“ACC”) is not constant due to manufacturing tolerances, erection tolerances and deflection of the actual support system and heat exchange cores. Because of this elevation difference, a zero welding gap cannot be maintained with the current two-dimensional flat tube sheets. That is, the two component heat exchange coils of an A-frame ACC cannot be welded directly to one-another.[0003]The typical arrangement of an air cooled condenser according to the current state of the art is shown in FIG. ...
