Abstract

A method of manufacturing a tube sheet by forming a plurality of separate thin tube sheet segments; forming multiple holes in each sheet in a predetermined pattern, each hole for accommodating a tube sheet filter tube; aligning all of the plurality of tube sheet segments so that the hole pattern of each sheet aligns with the hole pattern in all other sheets of the plurality of tube sheet segments; and securing all of the tube sheet segments together to form a unitary tube sheet. A tube sheet construction that includes a plurality of separate thin tube sheet segments, multiple holes being provided in each sheet in a predetermined pattern, each hole for accommodating a tube sheet filter tube, all of the tube sheet segments being aligning so that the hole pattern of each sheet aligns, and fasteners for securing all of the tube sheet segments together. A media layer is provided between adjacent sheet segments.

Claims (19)

1. A tube sheet construction that is comprised of a plurality of separate thin planar tube sheet segments that each extend across a complete width of the tube sheet construction, multiple holes being provided in each planar tube sheet segment in a predetermined pattern, each hole for accommodating an elongated tubular element, all of the planar tube sheet segments being aligning so that the hole pattern of each sheet aligns with the hole pattern in all other sheets of the plurality of planar tube sheet segments, at least one media sheet interposed between adjacent planar tube sheet segments, said media sheet comprised of one of a filtration layer and a nanotubular structure, and fasteners for securing the planar tube sheet segments and media sheet together in mutual intimate contact.

2. The tube sheet construction of claim 1 wherein each planar tube sheet segment is constructed of only a metal material.

3. The tube sheet construction of claim 1 wherein the plurality of separate thin planar tube sheet segments and the at least one media sheet together form a solid tube sheet structure.

4. The tube sheet construction of claim 1 wherein said media sheet comprises a planar media sheet.

5. The tube sheet construction of claim 4 including more than one planar media sheet disposed respectively between adjacent planar tube sheet segments.

6. The tube sheet construction of claim 1 wherein a means for forming each hole includes one of a punch device, a laser cutter, a plasma cutter, and etching device.

7. The tube sheet construction of claim 1 wherein each fastener is comprised of one of a rivet, bolt and screw.

8. The tube sheet construction of claim 1 including a cover disposed over the planar tube sheet segments.

9. The tube sheet construction of claim 1 wherein the media layer is also formed of one of a layer for flow control, shock absorption, magnetic characteristics, dosing, chemical or medical treatment, or ion exchange.

10. The tube sheet construction of claim 1 wherein the tube sheet construction forms part of one of a filtration device, a sanitation device, a reverse osmosis device, a distillation device, a condenser, an evaporator, a fuel cell, a transfusion device and a blood warming device.

11. The tube sheet construction of claim 1 wherein the media sheet is uniform in thickness so that any fluid that passes through the elongated tubular element also passes through the uniform thickness of the media sheet.

12. The tube sheet construction of claim 1 wherein the media sheet has one or more through holes for controlling through flow.

13. The tube sheet construction of claim 12 wherein at least some of the through holes in the media sheet are in alignment with the holes for accommodating the elongated tubular element.

14. The tube sheet construction of claim 1 wherein the media sheet comprises an active layer.

15. The tube sheet construction of claim 14 wherein the active layer senses pressure.

16. The tube sheet construction of claim 14 wherein the active layer senses temperature.

17. The tube sheet construction of claim 1 wherein the media sheet comprises a passive layer.

18. The tube sheet construction of claim 1 wherein the media sheet comprises an active layer that is externally excited.

19. The tube sheet construction of claim 18 wherein the active layer is excited by the application of a magnetic field.
