Indirect heat exchanger tube with controlled corrugated elbows

Abstract

1. Name of the design product: Controlled corrugated elbow for indirect heat exchanger tube. 2. Use of the design product: The design product is used for indirect heat exchanger tubes. 3. Design key points of the design product: Lies in the shape. 4. Picture or photograph that best shows the design key points: Perspective view. 5. Other situations that need to be explained: The dashed lines in the figure are only for illustrative purposes and do not form part of the claimed design. The dashed lines in the figure show a part of the controlled corrugated elbow of the indirect heat exchanger tube, which does not form part of the claimed design; the controlled corrugated elbow of the indirect heat exchanger tube has a symbolic break in its length. 6. The left view is a mirror image of the right view, and the bottom view is a mirror image of the top view, so the left view and the bottom view are omitted. 7. The drawing method of using natural break lines to disconnect in the top view, right view, and perspective view omits the intermediate length.
