However, this design is even more expensive than the bar-baffle design
Like the rod baffle design, the egg carton is also susceptible to tube chatter that can lead to tube failure

Embodiment Construction

[0033] The invention will now be described in more detail with reference to the accompanying drawings. Applicant indicates that the terms "horizontal" and "vertical" used in connection with the present invention are intended as reference points for describing the orientation of various parts of the bulkhead relative to other parts of the bulkhead. The term is not intended to describe the orientation of the baffles or the components that make up the baffles within the heat exchanger. It is intended that the tube bundle arrangement 1 may have one of a variety of orientations in use. Thus, the tube bundle arrangement can generally be oriented horizontally, vertically or at any angle relative to the horizontal.

[0034] figure 1 A tube bundle with multiple spaced apart baffles is shown. The tube bundle 10 is part of a tube bundle arrangement 1 (eg a heat exchanger or other suitable heat transfer component). Tube bundle 10 includes a plurality of parallel tubes 11 extending be...

Abstract

A tube bundle device having at least one displaceable baffle which supports the tubes in the bundle device is disclosed in order to reduce tube vibration. The displaceable baffle includes at least two displaceable portions, which can be moved to installed position such that tubes in a tube bundle are deflected.

Description

technical field [0001] The present invention relates to tube bundle arrangements of fluid handling equipment such as heat exchangers, condensers and similar with assemblies of tube or rod like elements, for example in assemblies such as nuclear reactors, chemical reactors, electric heaters or any parallel cylindrical shaped assemblies In a device, the assembly has fluid flow through a tube or other element. In particular, the present invention relates to displaceable baffles or support structures used in conjunction with tube bundles to provide support to the individual tubes within the tube bundle and to reduce vibration. The invention also relates to a method for reducing vibrations in a tube bundle of a heat exchanger. Background technique [0002] Tube bundle devices, such as shell and tube heat exchangers and other similar fluid handling devices (eg, chokes and deflectors) employ tubes combined into bundles in order to direct fluid through the device. In such tube bun...
