Definitions

  • the present invention relates to eutectic plates and in particular to eutectic plates adapted to be attached to the outer surface of cylindrical storage tanks, for example, refrigerated storage tanks.
  • a eutectic plate of arcuate configuration for ready attachment directly to the wall of a cylindrical storage tank comprises spaced apart first and second skins interconnected by members to define a plurality of compartments in which some compartments contain eutectic material while other compartments define passageways for the flow therethrough of a fluid.
  • each compartment is generally square in cross-section.
  • two eutectic plates 1 each have a generally arcuate configuration for ready attachment directly to the outer wall of, for example, a cylindrical refrigerated storage tank (not shown).
  • the plates 1 are fixed to the tank under the conventional insulation 2 usually surrounding the tank when containing chilled products.
  • Each plate 1 as shown comprises inner and outer skins 3, 4 interconnected by cross members 5 and a thin intermediate plate member 6 which define with the skins 3,4 a plurality of compartments 8 of generally square cross-section. Some compartments 8 are filled with eutectic material 10 whilst others particularly those adjacent the inner skin 3 define passageways 12 for the passage therethrough of a fluid.
  • the plates 1 are shown with one plate member 6 but it will be appreciated that eutectic plates can be constructed according to the present invention with a plurality of thin plates 6 and a plurality of thin members at right angles to the plates 6 and the skins 3,4 thereby to form a honeycomb type structure.
  • eutectic plates 1 will be formed with passageways 12 preferable adjacent the inner skin 3 said passageways 12 will be connected by headers so that for example, liquid nitrogen could be passed through these passageways 12 to chill the eutectic mixture 10. This is a rapid process and achieves in minutes full cooling which would normally take several hours. Since the passageways 12 are directly adjacent to the tank surface, cold will also be transferred to the tank contents thereby aiding the chilling process. Again, because of the short time period involved, once the eutectic plates 1 have frozen, virtually all the cold becomes available for cooling the tank contents.
  • the eutectic plates 1 can also be used for heating a tank by passing steam through the passageways 12 to warm the tank contents. In this situation, the eutectic material 10 will melt and will act as a transfer medium by convection and conduction around the periphery of the tank.
