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.
Claims20
A heat exchange apparatus, comprising:
- a heat exchange frame;
- a central plenum;
- a pair of heat exchange panels arranged in a heat exchange module on the heat exchange frame on opposite sides of the central plenum, the pair of heat exchange panels each comprising a plurality of tubes, wherein each of the tubes is connected to an inlet header and to an outlet header,
- the inlet header configured and located to receive process fluid and to distribute the process fluid to the plurality of tubes in a respective heat exchange panel of the pair of heat exchange panels, and
- the outlet header configured and located to receive the process fluid from the plurality of tubes in the respective heat exchange panel,
- wherein the heat exchange frame is open at a downward facing side and configured to allow entry of air from below the pair of heat exchange panels, wherein the pair of heat exchange panels is configured to receive ambient air from below;
- an elevating frame supporting each of the pair of heat exchange panels arranged so that ambient air flows upward through the pair of heat exchange panels from the downward facing side;
- and
- a fan module comprising at least one fan sized and positioned above and resting atop the heat exchange frame and configured to draw the ambient air from below and through the pair of heat exchange panels.
A heat exchange apparatus comprising:
- a plurality of heat exchange modules, including a first heat exchange module and a second heat exchange module, the second heat exchange module being adjacent the first heat exchange module;
- a plurality of heat exchange panels arranged and supported in the first heat exchange module and arranged and supported in the second heat exchange module as a plurality of V-shaped pairs,
- the heat exchange panels each comprising a plurality of tubes, the tubes each being fluidly connected to an inlet header and fluidly connected to an outlet header, the inlet header configured and located to receive process fluid and to distribute the process fluid to the plurality of tubes in a respective heat exchange panel and the outlet header configured and located to receive the process fluid from the plurality of tubes in the respective heat exchange panel, wherein the plurality of heat exchange panels are configured to receive ambient air;
- an elevating frame supporting the first heat exchange module and supporting the second heat exchange module;
- and
- a fan module having at least one fan sized and positioned to move air through the plurality of heat exchange panels.
A method for assembling a heat exchange apparatus, comprising:
- assembling an elevation frame at an installation location;
- mounting a plurality of pre-assembled and transportable heat exchange modules on the elevation frame, each of the pre-assembled and transportable heat exchange modules including a module frame, a first heat exchange panel, and a second heat exchange panel;
- and
- mounting and positioning a fan module above the plurality of pre-assembled and transportable heat exchange modules, the fan module including a fan configured to move air through each first heat exchange panel and through each second heat exchange panel.
