11041681 · 2021-06-22 ·

A clamping system secures to at least one tube in a tube bundle of a heat exchanger in order to reduce vibration damage. The clamping system includes a first clamping component having a J-shape, a second clamping component having an L-shape, a configuration where the first arc around the tube plus the second arc around the tube is equal to at least 100 degrees; and a means for resisting movement of the clamping components. The first clamping component with a J-shape covers a first arc around the tube. The second clamping component with an L-shape covers a second arc opposite the first arc. One of the means for resisting movement includes a stake, a nut, and a bolt.

Heat exchanger with heat exchange tubes moveable between aligned and non-aligned positions

A heat exchanger includes a plurality of heat exchange tubes arranged into a first row of tubes and a second row of tubes. A fixed mount fixedly positions the first row of tubes, and a movable mount makes the second row of tubes movable between an aligned position in which tubes in the second row are aligned with tubes in the first row, creating a linear flow path for the fluid through the tubes, and a non-aligned position in which tubes in the second row are not aligned with tubes in the first row, creating a curvilinear flow path for the fluid through the plurality of tubes. Heat is exchanged between the first fluid and a second fluid passing through the plurality of heat exchange tubes. The heat exchanger may be employed as an HRSG in a combined cycle plant, among other applications.

Helically coiled heat exchanger

A heat exchanger for indirect heat exchange between a first and a second medium is provided with a shell space for receiving the first medium, and a tube bundle arranged in the shell space and for receiving the second medium. The tubes are helically wound in a number of tube layers onto a core tube. The tube bundle includes a first tube layer which is positioned further outward in the radial direction of the tube bundle from an adjacent second tube layer. The heat exchanger includes at least one spacer and the first tube bundle is supported against the second tube bundle via the at least one spacer. The at least one spacer has a flow-directing region designed to deflect part of the first medium flowing along a tube of the first tube layer in the direction of the second tube layer situated further inwards in the radical direction.

RADIATOR AND LATERAL BUMP STOP THEREFOR

A radiator includes a radiator frame, an array of tube assemblies each including a coolant tube and a tube clip supported in the radiator frame, and a lateral bump stop fitted between the array of tube assemblies and the radiator frame.
