  • the sealing member 7 is fixed to the partition plate 6 so as to be suspended from, for example, the lower end of the wind shield 6a. Only the upper end portion of the sealing member 7 is fixed to the partition plate 6.
  • the sealing member 7 can seal the region from the upper end of the rectifying unit 6b to a predetermined height so that the conditioned air does not flow. That is, the sealing member 7 closes the rectifying unit 6b and blocks passage of the air-conditioned air through the hole 61.
  • the sealing member 7 may have a vertical dimension that can seal from the upper end to the lower end of the rectifying unit 6 b, that is, the bottom of the container 3.
  • the sealing member 7 is installed so as to be placed on top of the temperature adjustment object 10 when the temperature adjustment object 10 is accommodated.
  • the sealing member 7 is placed on the upper part of the temperature adjustment object 10 from the upper end of the rectifying unit 6b as shown in FIG. Block the area up to the height.
  • a region closed by the sealing member 7 of the rectifying unit 6b is referred to as an upper region.
  • the sealing member 7 blocks the upper region, thereby preventing the conditioned air from passing through the upper region.
  • the sealing member 7 is formed of a flexible sheet member, and can be easily put on the temperature control object 10. For this reason, even when the amount and arrangement of the temperature control object 10 change and the height of the temperature control object 10 changes, the upper region of the rectifying unit 6b can be reliably closed within the range of the vertical dimension. .
  • the temperature control storage device 1 includes a sealing member 7 that regulates ventilation of the conditioned air in the upper region of the rectifying unit 6b. According to this, when the height of the temperature adjustment object 10 is lower than the upper end of the rectification unit 6b, the conditioned air is passed between the upper end of the rectification unit 6b and the height of the upper part of the temperature adjustment object 10. Can be prevented. Therefore, a large amount of conditioned air can be passed through the temperature adjustment object 10, and the temperature adjustment performance can be further improved.
  • the temperature control storage device 1 of the fifth embodiment has a covering member 8 that can cover the upper part of the temperature control object 10.
  • the covering member 8 is provided by a flexible sheet member having a predetermined area, for example.
  • the covering member 8 is installed on the temperature control object 10 in a state where it is not fixed to the other members of the temperature control storage device 1.
  • the covering member 8 may be fixed so as to be suspended from a predetermined member of the temperature control storage device 1, for example, a ceiling portion or a wall portion of the storage chamber 30A.
  • the covering member 8 blocks the ventilation of the conditioned air by covering the upper part of the temperature control object 10. Therefore, it is possible to suppress the air conditioning air from being concentrated and passed near the upper portion of the temperature control object 10, so that temperature control unevenness can be further improved.
  • the plurality of holes 61 formed in the rectifying unit 6b are uniform in number and size throughout, but the number and size are changed depending on the region. Also good.
  • the plurality of hole portions 61 may be configured such that the number is reduced or the size is reduced toward the upper portion of the rectifying portion 6b.
  • the rectifying unit 6b may have a configuration in which the ventilation resistance increases toward the top. In this configuration, the airflow rate of the conditioned air becomes smaller toward the upper part of the rectifying unit 6b.
  • the partition plate 6 is a single plate member in which the wind shielding portion 6a and the rectifying portion 6b are formed.
  • the partition plate 6 may be composed of two plate members, a wind shield plate and a current plate.
  • the rectifying unit is formed with the plurality of holes 61, but is not limited to this configuration as long as the conditioned air can pass while receiving the ventilation resistance.
  • the rectifying unit may have a configuration in which a plurality of slits are formed side by side. At this time, it is desirable that the plurality of slits have a uniform arrangement because the flow rate of the conditioned air is more uniform.
  • the rectifying unit may have a configuration in which a plurality of plates are arranged with a gap therebetween.
  • the partition plate 6 is a metal flat plate.
  • at least one of the wind shielding portion 6a or the rectifying portion 6b may be a plate member other than metal.
  • FIG. For example, a vinyl sheet in which holes or slits are formed in the rectifying unit 6b may be applied as the partition member.
  • the partition plate 6 is fixed to the container 3.
  • the partition plate 6 may be configured to be movable with respect to the container 3.
  • the partition plate 6 may be attached to a rail portion installed in the container 3, and the partition plate 6 may be movable in the depth direction along the rail portion. If it is this structure, since the volume of 30 A of storage chambers can be changed, the amount which can accommodate the temperature control object 10 can be changed arbitrarily.
  • the temperature control storage apparatus 1 was provided with the wind direction adjustment board, the structure which is not provided with a wind direction adjustment board may be sufficient. Even in the case where the wind direction adjusting plate is not provided, if the conditioned air blows into the storage chamber 30A, the conditioned air in the storage chamber 30A is sucked by the partition plate 6, so A flow layer can be formed.
