Definitions

  • ABSTRACT Capillary insulation for low temperature liquids in l61/68,l6l/ll3, 161/127,
  • FIGZ //VVEA/7'OR C773 Y L. M 'GREW Patented Aug. 28, 1973 7 3,755,056
  • This invention relates to insulating structures and, more particularly, to an improved insulation for use with low temperature liquids.
  • the insulation comprises a cellular structure which provides a plurality of discrete cells in which a gas column is established between the container wall and the body of liquid.
  • a capillary cover substantially closes the liquid side of each cell with the cover having at least one capillary opening per cell.
  • the capillary openings are so designed that a stable capillary gas-liquid interface or membrane is formed at the capillary opening.
  • gas columns and their associated stable gas-liquid interfaces insulate the liquid from the container walls and, in addition, support the liquid in the container thereby permitting fabrication of the cellular structure from materials which have low strength and weight as well as low thermal conductivity.
  • the cellular structure may be fabricated from various materials.
  • the low structural requirements of the cellular struc-- ture results in a construction in which the cellular material actually contacts but a very small area of the surface of the container while the gas columns contained within the cellular structure cover a far larger area of the container wall.
  • the thermal conductivity of the insulation approaches that of gas in the cells.
  • the small amount of cellular material required to form the cellular structure reduces both the thermal conduction through the material and the liquid boil-off required to cool the insulation to the operating temperature.
  • Such loading can have an effect on the operation of the insulation.
  • the size of the capillary openings in the capillary cover is important in establishing and maintaining the desired gas-liquid interface. Loads imposed on the capillary cover, which is very thin and flexible, could cause enlargement or even tearing of the opening, in which event the liquid-gas interface would be adversely effected. Another example is deflection may be experienced by the insulation structure which in many instances will cause physical damage to the structure.
  • a capillary insulation comprising a cellular structure which provides a plurality of contiguous discrete cells with a capillary cover closing one side of the cells and capillary openings in the cover communicating with each cell.
  • the cellular structure is so formed that the cell walls have an excess of material between points of interconnection.
  • this excess material is characterized by cell walls which are S-shaped in cross-sectional configuration. This is achieved by forming the cells from a plurality of strips of material each of which is in the form of a sine wave with adjacent strips being staggered and connected at spaced points therealong.
  • the resultant cells have cell walls of the aforementioned S-shaped configuration which permit the individual cell walls to expand and contract relative to the other cells and prevents stress accumulation in the panels.
  • the principles of the invention further contemplate minimizing stress buildup in the capillary cover by providing excess cover materialfor each of the cells.
  • the excess cover material may be provided in the form of dimples of folds in the capillary cover. In this way, the capillary cover over each cell may deflect as required to accommodate such stresses and strains as are imposed on the individual cells without affecting the adjacent cells.
  • each of the capillary openings with a reinforcing rib or torous which extends around the periphery of each opening.
  • This toroidal reinforcement minimizes any tendency of the capillary cover to tear at the capillary opening and insures that stresses imposed on the capillary cover will not enlarge the dimension of the opening.
  • FIG. 1 is a perspective view of a portion of the capillary insulation constructed in accordance with the principles of this invention
  • FIG. 2 is a sectional view along line 2-2 of FIG. 1;
  • FIG. 3 is a plan view schematically illustrating the strips from which the cellular material is constructed
  • FIG. 4 is a top plan view of the assembled capillary insulation with a portion of the capillary cover removed to expose the cellular construction;
  • FIG. 5 is a schematic illustration of the method by which the capillary insulation of FIG. 1 may be produced.
  • FIG. 1 a capillary insulation assembly indicated generally by the reference numeral 10.
  • the capillary insulation is secured to and carried by a support wall 12 which may be the wall of a tank or any other surface which it is desired to insulate from a low temperature boiling point liquid.
  • the insulation assembly comprises a cellular I structure 14 which includes a plurality of discrete cells 16 and a closure means in the form of a capillary cover 18 extending across the cells and secured by suitable means such as an adhesive 19 to the cellular structure 14.
  • a suitable filling not shown, such as rock wool or polystyrene chips, may be provided in the cells to reduce radiation and convection currents.
  • Capillary openings, holes or pores 20 are formed in the cover 18 with each opening being associated with one of the cells 16.
  • the cellular structure 14 may be fabricated of any lightweight material which is compatible with the liquid being insulated and which has a low thermal conductivity.
  • plastic impregnated Kraft paper may be used. Both materials are relatively flexible in all directions transverse to the plane of the paper.
  • the capillary cover 18 may be made from a suitable plastic film such as one-mil Mylar film.
  • the capillary insulation contemplates the formation of a plurality of discrete gas columns within the cells 16 with the gas columns extending between the surface of the wall 12 and the liquid.
  • the size of the openings 20 are such that a stable capillary interface or membrane is formed at the interface of the gas columns and the liquid, with the membrane preventing liquid from penetrating the gas column so that the gas columns function as insulators.
  • the gas columns provide support for the liquid so that the relatively weak cover 18 need not support the liquid.
  • the cellular material 14 is constructed such that an excess of wall material is available to permit expansion and contraction of individual cells independently of adjacent cells. This is accomplished in the preferred embodiment by forming each quarter or 90 segment of the cell wall in generally S-shaped configuration. As shown in FIG. 4, each cell is defined by four quarter segments of the cell wall. These quarter segments extend respectively between points A,B; B,C; AD; and D,C. It will be noted that the cross-sectional configuration of each of the four quarter segments of the cell wall, extending between any two of the points A, B, C and D, is generally S-shaped in configuration.
  • the quarter segment of the cell wall extending between points A and B and designated 24, includes a first arcuate portion 25 which bows inward of the cell and a second ar cuate portion 26 which bows outward of the cell.
  • Each point along each of the portions 25,26 has a radius as measured from the longitudinal axis 27 of the cell which differs from the radius of the next adjacent point in that portion of the wall.
  • the distance between the two points A,B along the dotted straight line 32 is substantially less than the distance between the same two points as measured along the curving surface of that segment 24 of the cell wall. Accordingly, it should be apparent that more material is provided in the segment 24 due to the curved configuration thereof than if the segment 24 was straight.
  • the excess material thus pro vided constitutes means which permits the wall 24 to deflect transverse to the axis of the cell without altering the distance between points A and B.
  • the contrac tion does not put any undesirable stress or strain on the material, notwithstanding the fact that the entire bottom edge of each cell is fixedly attached to the container wall; rather, the quarter segment tends to straighten out from the full-line position shown in FIG. 4 toward a position represented by the dotted line 32 shown in FIG. 4.
  • the material upon contraction to pull points A and B, for example, together which would result in a large total deflection of the insulation structure due to the fact that this would be magnified from cell to cell.
  • a cellular structure having S-shaped walls may be fabricated in various ways but in the preferred form is achieved by fabricating the structure from a plurality of individual strips or ribbons of material which are then assembled in the configuration shown in FIG. 4.
  • FIG. 3 two strips or ribbons 30,32 as they are shaped in the assembled structure are illustrated.
  • Each of the strips is in the general form of a sine wave defined by loops 30a, 30b and 32a, 32b extending in opposite directions on either side of the neutral axes 31,33 of the strips.
  • the strips are assembled by offsetting one strip from the other in the manner shown in FIG. 2 so that every loop 30a of one strip extending in one direction engages every loop 32b of the other strip extending in the opposite direction.
  • Adhesive means 34 may be used to securely fasten the two abutting loops together. However, it should be noted that the area over which the adhesive 34 is applied is relatively small so that the cell walls immediately adjacent the adhesive remain free to deflect.
  • the capillary cover 18 is illustrated as being non-planar, having a concave or dishshaped configuration over each of the cells 16 so that the distance across the cell as measured along the surface of the cover 18 is greater than the corresponding width of the cell.
  • This excess of material permits the capillary cover for each cell to deflect between the positions shown in solid lines and the position shown in dotted lines in FIG. 2. This enables the capillary cover to accommodate strains imposed on each individual cell without transmitting these strains or stresses to adjacent cells.
  • the cover When the liquid having a low boiling point is poured into the container and contacts the cover 18, the cover, as discussed above in connection with the material of the cell walls, also tends to contract due to the temperature change therein.
  • the cover 18 is made of polyethylene terethphalate film marketed under the trademark Mylar. This contraction results in the Mylar cover deflecting from its full-line position, shown in FIG. 2, to the dotted position shown in FIG. 2. Due to the fact that the cover deflects in this manner, which is possible because of the excess material provided therein, a minimum of stress is imposed in the cover due to the temperature change therein.
  • the dimpled cover construction insures that the size of the capillary opening 20 remains substantially constant even when the capillary cover is subjected to stresses and strains resulting from contact with the liquid.
  • This benefit is best understood by considering the capillary cover as being stretched taut across each cell 16. Under those conditions, any temperature change in the cover 18 results in stresses therein and, which may alter the size of the opening 20. Since the dimensions of the capillary openings 20 are of critical importance to the maintenance of the proper capillary interface between the liquid and gas, any change in the size of the opening will have an adverse effect on that interface.
  • sufficient excess cover material is provided to permit deflection of the cover without causing undue stretching of the cover.
  • This additional provision is illustrated in FIG. 2 and comprises reinforcement means 36 which extend around each of the openings 20.
  • this reinforcement means comprises a thickened section of the cover which, in cross section, is in the form of a torous.
  • the toroidal reinforcement 36 thus provides additional strength at the capillary openings so that any tendency of the openings to enlarge or tear when the cover is under stress is effectively resisted.
  • FIG. 5 there isschematically illustrated one method by which the described insulation may be produced.
  • a plurality of strips of the type shown in FIG. 3 are assembled.
  • the strips may be previously corrugated to the desired configuration and adhesive applied to the points 34 where the adjacent strips are to be interconnected.
  • the strips are then moved together and the adhesive allowed to harden to form the basic cellular structure.
  • adhesive is applied to the upper edges of the joined strips.
  • a film is then layed over the cellular structure and in engagement with the applied adhesive. After the film is attached, pressure differential is'established across the film as shown at step (c). While the pressure differential is applied, heat is also applied to the cover.
  • the pressure differential is in the form of a vacuum
  • the combination of heat and vacuum dimples the cover over each cell by stretching the film beyond its elastic limit and pulling the film a small distance down into the cell.
  • the vacuum is applied after the adhesive has set up and secured the cover to the cellular structure so that the stretching of the film occurs only in each individual cell.
  • the dimpled cellular structure is moved to step (d) where a plurality of heated needles 40 pierce the holes 20 in the dimpled capillary cover. These needles melt the film in the area immediately adjacent to the pierced hole causing the plastic material to flow. away from the hole and form the desired toroidal configuration shown in FIG. 2. The needles are then withdrawn and the completed insulation is ready for use.
  • the described insulation is well suited to achieving the objectives set forth.
  • the cellular structure is designed to accommodate thermal strains resulting from temperature changes therein.
  • the capillary cover is designed to minimize development of stresses.
  • the critical sized capillary openings are designed to maintain the desired opening dimension even when the cover is subjected to stresses.
