It is a figure which shows the outline of the conveyance box which concerns on embodiment of this invention. It is an enlarged view of the area | region A of FIG. It is explanatory drawing of the conveyance box which concerns on background art.

  Hereinafter, typical embodiments of the present invention will be described in detail with reference to the drawings. Since the drawings are for conceptual description of the present invention, dimensions, ratios, or numbers may be exaggerated or simplified as necessary for easy understanding.

[Overall configuration of transport box]
With reference to FIG. 1, the whole structure of the conveyance box 1 which concerns on this embodiment is demonstrated. The transport box 1 is a container suitable for transporting a transported object 90 such as a blood product while maintaining it in a preset temperature band. The transport box 1 includes a heat insulating container 10, a heat insulating lid 20, a cooling unit 30, and a component storage unit 40.

  The heat insulating container 10 is a heat insulating container that opens toward the upper surface. The heat insulating container 10 includes a casing 11, a heat insulating material 12 included in the casing 11, and a heat transfer container 13.

  The casing 11 is a housing formed of synthetic resin such as polypropylene or ABS resin, or metal. As will be described later, the casing 11 has an opening 61 on the outer peripheral surface for mounting the cooling unit 30.

  The heat insulating material 12 is interposed between the casing 11 and the heat transfer container 13, and is formed of, for example, injected rigid foamed urethane, vacuum heat insulating material, foamed polystyrene, or a combination thereof. The heat insulating material 12 is also provided between the cooling unit 31 and the heat radiating unit 32 of the cooling unit 30.

  The heat transfer container 13 is an inner container that is mounted inside the heat insulating container 10 and has excellent heat transfer properties, and can store the conveyed product 90. In the present embodiment, the heat transfer container 13 opens toward the upper surface of the heat insulating container 10. The heat transfer container 13 is formed of, for example, aluminum whose surface is anodized so that heat from the cooling unit 30 is efficiently transferred to the entire heat transfer container 13.

  The heat insulation lid 20 is a heat insulation lid that closes the opening 15 of the heat insulation container 10 so as to be freely opened and closed. The heat insulating lid 20 includes a casing 21 and a heat insulating material 22 included in the casing 21. The material of the casing 21 and the heat insulating material 22 may be the same as the material of the casing 11 and the heat insulating material 12 of the heat insulating container 10, respectively.

  The cooling unit 30 is a temperature control unit that maintains the temperature in the heat transfer container 13 in a preset temperature range. For example, when the conveyed product 90 is a blood product, the cooling unit 30 sets the internal temperature to a first temperature band (2 ° C. to 6 ° C.) suitable for storing red blood cells, and a second temperature suitable for storing platelets. It can be maintained in either the zone (20 ° C. to 24 ° C.) or a third temperature zone (−20 ° C. or lower) suitable for storage of frozen plasma.

  The cooling unit 30 is arranged from the outer surface of the heat transfer container 13 to the outside of the casing 11, and includes a cooling unit 31 located in the casing 11 and a heat radiating unit 32 located outside the casing 11. The cooling unit 30 is sealed with a sealing material 63 so that the cooling unit 31 is not exposed to the outside air. This point will be described later.

  The cooling unit 31 is a member that adjusts the temperature in the heat transfer container 13 based on an instruction from a control unit (not shown). The cooling unit 31 is fixed by fixing means such as screws 51 and 52 and extends toward the opening 61 of the casing 11 while being in contact with the outer peripheral surface of the heat transfer container 13. The cooling unit 31 includes an electronic cooling element such as a Peltier element, and thermal conductors interposed between the electronic cooling element and the heat transfer container 13 and between the electronic cooling element and the heat dissipation unit 32, respectively. Including.

  The heat radiating part 32 is a member that is connected to the cooling part 31 and releases the heat generated in the cooling part 31 to the outside. The heat radiating part 32 includes a radiator such as a heat radiating fin and a fan (not shown) that blows cooling air to the radiator.

The heat radiating part 32 is disposed outside the casing 11. Further, as will be described in detail later, the heat radiating portion 32 is fixed to the casing 11 by fixing means such as screws 53 and 54 (see FIG. 2).
Therefore, the cooling unit 30 is fixed to both the outer surface of the heat transfer container 13 and the casing 11.

  In addition to the heat radiating unit 32 of the cooling unit 30, the component storage unit 40 stores components (not shown) such as a power supply control board (control unit), a built-in battery, and a recording / display unit.

  The transport box 1 having the above-described configuration can maintain the storage space 14 including the transported object 90 in a preset temperature band regardless of changes in the external environment. Therefore, the transport box 1 is configured so that the blood product is supplied in the first temperature range (2 ° C. to 6 ° C.), the second temperature range (20 ° C. to 24 ° C.), or the third temperature range (−20 ° C. or less). Any of these can be maintained.

[Cooling unit fixing structure and sealing structure]
A fixing structure and a sealing structure of the cooling unit 30 will be described with reference to FIG.
As described above, the opening 61 for attaching the cooling unit 30 is formed on the outer peripheral surface of the casing 11. The cooling unit 31 of the cooling unit 30 is inserted into the opening 61. The cooling unit 31 is fixed to the outer peripheral surface of the heat transfer container 13 by fixing means.

  The heat dissipating part 32 of the cooling unit 30 is fixed to the outer peripheral surface of the casing 11 by fixing means such as screws 53 and 54 at a portion 33 facing the outer peripheral surface of the casing 11. The fixing means may be other means such as adhesion, and a plurality of fixing means may be used in combination.

  Thus, the cooling unit 30 is fixed in both the heat transfer container 13 and the casing 11. Therefore, it is possible to suppress a gap from being generated between the cooling unit 30 and the heat insulating material 12 due to an external force acting on the transport box 1 due to the drop or vibration of the transport box 1.

  The edge 62 that forms the opening 61 of the casing 11 is bent toward the outside of the casing 11. Therefore, in a state where the cooling unit 30 is fixed to the heat transfer container 13 and the casing 11, the tip of the edge portion 62 faces the heat radiating portion 32 side of the cooling unit 30.

  A sealing material 63 is interposed between the casing 11 and the cooling unit 30 in order to maintain airtightness in the casing 11. Specifically, the sealing material 63 is provided along the outer peripheral surface of the edge portion 62. The sealing material 63 is packing, for example. The sealing material 63 is preferably formed of a synthetic rubber that has extremely low gas permeability and is chemically stable, such as butyl rubber.

  The heat insulating material 12 is also filled between the opening 61 (edge 62) of the casing 11 and the cooling unit 31 so that the cooling unit 31 of the cooling unit 30 is not exposed to the outside air. It is adhered to the portion 34 facing the opening 61 of the above. It can be said that the portion 34 facing the opening 61 is the periphery of the connection portion with the cooling portion 31 in the heat radiation portion 32.

  A water receiver (not shown) for receiving water leaking from the casing 11 may be installed below the heat radiating portion 32.

  As described above, in the present embodiment, the cooling unit 30 is fixed to both the heat transfer container 13 and the casing 11, so that the cooling box 30 and the heat insulating material 12 can be moved together with an impact caused by dropping or vibration of the transport box 1. It is possible to prevent a gap from occurring in the substrate. Thereby, it can suppress that the cooling unit 30 (cooling part 31) dew condensation.

  Moreover, the cooling unit 30 (cooling part 31) can be sealed from the outside by the sealing material 63 attached to the edge part 62 of the casing 11. Therefore, dew condensation in the cooling unit 31 is suppressed, and even when a gap is generated between the cooling unit 30 and the heat insulating material 12, moisture generated due to dew condensation on the cooling unit 30 is prevented from leaking outside the casing 11. can do.

  Further, since the heat insulating material 12 is also provided between the cooling portion 31 and the heat radiating portion 32, that is, due to the expansion of the bonding surface of the heat insulating material 12, there is a gap between the casing 11 and the cooling unit 30 (heat radiating portion 32). Even if it arises, the cooling unit 30 (cooling part 31) can be thermally insulated from the outside. Thereby, generation | occurrence | production of the dew condensation in the cooling unit 30 is further suppressed.

  As mentioned above, although typical embodiment of this invention was described, this invention is not limited to these, A various design change is possible and they are also contained in this invention.
