Abstract:
Air cooled chillers having a condenser section (300) sized to match chiller capacity and auxiliary cooling requirements satisfied by use of an independent cooling coil (314) dedicated to providing auxiliary cooling. The independent cooling coil (314) is located within the current condenser (300), but utilizes available space within the existing condenser, as well as a small portion of the airflow driven by the existing condenser fan (320). Thus, the auxiliary cooling capacity is provided with a single dedicated coil design, but which otherwise uses existing equipment and space.
Abstract:
A submersible heat-exchanging apparatus comprises a cylindrical heat-exchange component configured with one end for sealingly engaging a terminal plug and the other end for sealingly engaging and communicating with a coupling manifold having opposed inflow and outflow ports. A flow-directing elongate insert is provided with one end configured to engage the coupling manifold interposed the inflow and outflow ports, and the other end provided with an aperture and configured for abutting the terminal plug. The flow-directing elongate insert is configured to slidingly contact and cooperate with the inner walls of the heat-conductive conduit thereby partitioning the heat-conductive conduit into two opposed fluid transmission channels wherein one channel communicates with the inlet port and the other channel communicates with the outlet port. The coupling manifold is configured to sealingly engage an aperature provided therefore in a fluid-containing receptacle whereby the heat-exchange component extends into the receptacle.

Abstract:
An air-liquid heat exchanger consists in an insulated chamber adapted to allow hot air to pass therethrough. A coil member extends through the insulated chamber and is adapted to allow a heat transfer liquid to pass into and then out of the insulated chamber. There is at least one bracket adapted to hold the coil member in a predetermined position and spacing between the windings of the coil within the insulated chamber, and at least one baffle member placed between the coil member and an interior surface of the insulated chamber and adapted to slow down the speed of air flow through the insulated chamber. A slower air speed increases the time and number of contacts between the hot air and the coil member and thereby allows for an efficient exchange from the hot air to the heat transfer liquid.
Abstract:
A tube bundle is provided for a shell-and-tube heat exchanger. The tube bundle includes a plurality of elongated tubes, each of which has an intermediate portion that has a cross section in the form of a flattened circle with at least one axis of symmetry. The tubes are arranged in concentric circles with the axis of symmetry extending tangentially to the circle to facilitate rotational flow of a shell-side fluid.

Abstract:
A compact evaporator (180, 280, 380) including a suction baffle system (116) is provided for use in a refrigeration system (10). The suction baffle system (116) includes a suction baffle (150) and a passageway (120). The suction baffle (116) includes a plurality of walls (152) and is adjacent to the interior wall (156) of the evaporator shell (114). The passageway (120) extends below one of the walls (152) of the suction baffle (116) toward the lower portion (148) of the shell (114) and is adjacent to the interior wall (156) of the shell (114). A suction tube (113) having an inlet (111) is attached to the evaporator shell (114) and the inlet (111) is adjacent to the passageway (120) and located partially below the suction baffle (116). The passageway (120) minimizes the possibility of liquid refrigerant (138) carry-over in the suction tube (113) that feeds into the compressor (60).
