Abstract:
1. A tube support for use within a shell and tube heat exchanger comprising: (a) at least two first plates; and (b) at least two second plates, said first plates and said second plates interlocked so as to form a grid of depth-wise planar extent with at least one square-shaped opening, each said first plate and each said second plate having a plurality of u-shaped curvilinear nodules, at least one said u-shaped curvilinear nodule along each said first plate and along each said second plate extending into each said square-shaped opening so that each said square-shaped opening has at least four said u-shaped curvilinear nodules therein, each said u-shaped curvilinear nodule having a length that is less than one-half the depth of said grid so that at least two said u-shaped curvilinear nodules are aligned depthwise along said grid, oppositely disposed about said plate, and centered within said square-shaped opening, each said u-shaped curvilinear nodule having an opening there under which is no longer and no wider than said u-shaped curvilinear nodule so as to prevent fluid flow between adjacent said square-shaped openings, at least four said u-shaped curvilinear nodules contacting a hollow tube so as to be slidable and centrally positioned therein.
