Abstract
A modular double V stacked dry or adiabatic heat exchanger having a bottom module with two heat exchangers arranged in a V-shape, a top module configured to rest atop and be supported by the bottom module and having two heat exchangers configured to continue and extend the V-shape formed by the two bottom heat exchangers, and a fan module configured to rest atop and be supported by the top module. The modules are factory assembled and configured to for easy shipping and connection to one-another on-site. Adiabatic pads or spray nozzles may be provided to pre-cool the air entering the system.
Claims19
A modular V-shaped heat exchange apparatus, comprising:
- a factory assembled and transportable bottom heat exchange module having a bottom module frame and two bottom module heat exchange panels arranged and supported in said bottom module frame in a V-shape,
- a factory assembled and transportable top heat exchange module having a top module frame and two top module heat exchange panels arranged and supported in said top module frame so that said two top module heat exchange panels continue and extend the V-shape formed by said two bottom module heat exchange panels, said top heat exchange module supported by said bottom heat exchange module;
- a factory assembled and transportable fan module having a fan module frame and at least one fan, said fan module positioned on top of and supported by said top heat exchange module, said at least one fan positioned and configured to draw air through said two bottom module heat exchange panels and said two top module heat exchangers.
A heat exchange apparatus comprising a plurality of heat exchange panels arranged and supported in a plurality of V-shaped pairs, said heat exchange panels each comprising a plurality of horizontal tubes, each horizontal tube connected to an adjacent horizontal tube via a return bend, said horizontal tubes each connected to an inlet header at a first end and to an outlet header at a second end, said inlet header configured and located to receive hot process fluid and to distribute it to said plurality of horizontal tubes in a respective heat exchange panel and said outlet header configured and located to receive cooled process fluid from said plurality of horizontal tubes in said respective heat exchange panel, wherein said plurality of heat exchange panels are configured to receive ambient air from below;
- said heat exchange apparatus further comprising an elevating frame supporting each of said plurality of said plurality of V-shaped pairs of heat exchange panels;
- and a fan module comprising at least one fan sized and positioned above said plurality of heat exchange panels to draw air through said plurality of heat exchange panels.
(canceled)
A method for assembling a heat exchange apparatus, comprising:
- assembling an elevation frame at an installation location;
- mounting on said elevation frame a plurality of a factory assembled and transportable bottom heat exchange modules, each having a bottom module frame and two bottom module heat exchange panels arranged and supported in said bottom module frame in a V-shape, mounting above each of said bottom heat exchange modules a respective factory assembled and transportable top heat exchange module having a top module frame and two top module heat exchange panels arranged and supported in said top module frame so that said two top module heat exchange panels continue and extend the V-shape formed by two of said two bottom module heat exchange panels;
- mounting and positioning above said top heat exchange module a fan configured to draw ambient air into a plenum formed by said elevation frame and up through a plurality of said bottom heat exchange modules and plurality of said top heat exchange modules.
