  • the ends may be heat sealed or may be otherwise compressed or crimped.
  • end caps 76 are provided.
  • End caps 76 may also be made from HDPE and may be spin-welded to the ends of containers 60. As caps 76 are spin-welded into place, the outer surfaces of caps 76 and the inner surface of container 60 partially melt, bonding and hardening when caps 76 cool and thus providing a hermetic seal.
  • containers 60 are preferably corrugated containers 60 as shown in Fig. 3.
  • the corrugated rings 78 on the exterior surface of each container 60 may vary in size, shape, and spacing.
  • the corrugated rings 78 of adjacent containers 60 will be in contact, advantageously leaving the interstitial spaces 80 open to form a passageway for airflow through the array as shown best in Fig. 3.
  • corrugations 78 when containers 60 expand during phase change, corrugations 78 will tend to flatten, restricting the passageway for air through the array and reducing the rate of heat transfer. This will advantageously allow for slow initial discharge rates during a heat discharge cycle, with increasing rates later in the cycle. The opposite is likely to occur in cooling discharge cycles. That is, the passageway for air through the array will be relatively unrestricted during the initial phase of the cooling discharge cycle, and will gradually become more restricted as container 60 expands and corrugations 78 flatten out. Thus, corrugations 78 provide, in effect, a means for self-regulating the airflow passageway through interstitial spaces 80. Of course, these effects are likely to vary depending upon the type of PCM 82 which is used.
  • corrugated containers 60 provide numerous additional advantages.
  • the corrugated containers 60 have a greater external surface area for heat transfer than do smooth-walled containers of the same dimensions.
  • corrugations 78 assist crystal growth in the PCM by providing increased probability of surface imperfections which can provide points for crystal nucleation.
  • Corrugations 78 provide constantly changing contours preventing large linear crystal growth that might otherwise puncture or damage containers 60.
  • Corrugations 78 may also provide a deterrent to PCM stratification during phase change transition. It is thought that the additional surface area offered by corrugations 78 will promote equal distribution of solid PCM particles throughout the entire interior volume of container 60, avoiding the accumulation of a high concentration of solid PCM at the bottom of containers 60. Additionally, the corrugations 78 provide superior structural properties as compared to smooth walled containers. This is particularly important in the present application where leakage of PCMs may corrode or otherwise cause damage to thermal storage unit 20.
  • a wide variety of PCMs 82 may be used in connection with the present invention. PCMs are typically chosen based upon their latent heat characteristics, but may also be selected for their additional qualities, such as congruent melting, minimal supercooling. Typical classes of PCMs usable in accordance with this invention include paraffin waxes, eutectic mixtures of salts, salt hydrate solutions, and water.
