(Outer wall portion 20 and inner wall portion 30)
The container unit 10 of the present embodiment has the following heat insulating structure on the ceiling surface 12e, the side surface 12c, the floor surface 12f, and the side surface 12a among the six surfaces forming the internal space S1 in the container portion 12. I have.

FIG. 2 is a 2-2 cross-sectional view of the side surface 12c of the container unit of FIG. Here, the configuration of the side surface 12c will be described with reference to FIG. 2, but the other ceiling surface 12e, floor surface 12f, and side surface 12a are assumed to have the same configuration, although the arrangement directions are different.

As shown in FIG. 2, the side surface 12 c of the container portion 12 of the container unit 10 of the present embodiment includes an outer wall portion 20 and an inner wall portion 30 that are arranged substantially parallel to each other.

As shown in FIG. 2, the outer wall portion 20 is disposed on the outside air side of the side surface 12c, and includes an aluminum plate 21 that is a second surface, a heat insulating material 22 that is a heat insulating space, and an aluminum plate 23.

The aluminum plate 21 is made of, for example, an aluminum plate having a thickness of about 0.8 mm, and forms the outermost surface in contact with the outside air.

The heat insulating material 22 is provided between the aluminum plate 21 and the aluminum plate 23 so that the temperature inside the container portion 12 is not affected by the temperature of the outside air. And the heat insulating material 22 is comprised using the urethane foam, for example.

The aluminum plate 23 is, for example, a plate-shaped member made of aluminum, and has a first concavo-convex structure, which will be described in detail with reference to FIG. 3, on the first surface that is the surface facing the internal space S 1, that is, the side facing the inner wall portion 30. It has an uneven structure 23a. In addition, the aluminum plate 23 forms a circulation path S2 in a gap between the aluminum plate 23 and the inner wall portion 30 that is disposed to face the gap through a predetermined gap.

As shown in FIG. 2, the inner wall portion 30 is disposed on the side of the inner space S1 on the side surface 12c with a predetermined gap with respect to the aluminum plate 23 of the outer wall portion 20. The inner wall portion 30 has a resin plate 31, a convex portion 32, and a through hole H.

The resin plate 31 is, for example, a resin plate-like member, and has a second concavo-convex structure, which will be described in detail with reference to FIG. 5, on the third surface that is the surface of the outer wall portion 20 facing the aluminum plate 23. It has an uneven structure 31a. The resin plate 31 is provided with a convex portion 32 on the surface on the internal space S1 side. Further, the resin plate 31 has a through hole H that allows the internal space S1 and the circulation path S2 to communicate with each other at a predetermined interval. As described above, the resin plate 31 forms the circulation path S <b> 2 in the gap between the resin plate 31 and the outer wall portion 20 disposed so as to face the gap through the predetermined gap.

As shown in FIG. 2, the convex portion 32 is a quadrangular member in cross-sectional view, and is disposed on the fourth surface, which is the surface of the resin plate 31 on the internal space S1 side. And the convex part 32 is arrange | positioned for every predetermined space | interval along the direction of the 1st airflow F1, and is extended | stretched along the substantially horizontal direction.

Thereby, since the convex portion 32 is formed on the inner surface of the internal space S1, it is possible to prevent the cargo from being arranged so as to contact the inner surface. Therefore, even when the container unit 10 is fully loaded with cargo, it is possible to secure a route through which the air temperature-controlled by the air conditioning unit 11 passes into the internal space S1, so that the efficiency of the air conditioning unit 11 can be improved. .

As shown in FIG. 2, the through hole H is formed so as to penetrate the resin plate 31 so that the internal space S1 and the circulation path S2 communicate with each other. And the through-hole H is arrange | positioned for every predetermined space | interval in the direction of the 1st airflow F1 similarly to the convex part 32, and the opening part is extended along the substantially horizontal direction. Further, the through hole H is located at a position facing the concave portion of the concavo-convex structure 23a so that the second air flow F2 generated by the concavo-convex structure 23a of the aluminum plate 23 described later escapes from the circulation path S2 toward the internal space S1. Is provided.

(Uneven structure 23a)
FIG. 3 is a perspective view showing the configuration of the first surface of the outer wall portion of the container unit of FIG. 1. FIG. 4 is an enlarged schematic view of the main part P1 of FIG. In the container unit 10 of the present embodiment, as described above, the concavo-convex structure 23a is formed on the first surface of the aluminum plate 23 constituting the outer wall portion 20, that is, the surface side facing the resin plate 31 of the inner wall portion 30. I have.

As shown in FIG. 3, the concavo-convex structure 23a is configured by alternately arranging a plurality of concave portions and convex portions in a grid pattern.

Further, as shown in FIG. 4, the first air flow F1 generated in the circulation path S2 passes through the surface of the concavo-convex structure 23a.

At this time, as shown in FIG. 4, a part of the first air flow F1 causes a stay F2a due to the concave portion of the concavo-convex structure 23a, thereby generating an air flow F2b in a direction substantially perpendicular to the first air flow F1. . Note that the air flow that combines the stay F2a and the air flow F2b is the second air flow F2.

And as shown in FIG. 4, the 2nd airflow F2 produced by the recessed part of the uneven structure 23a of the resin board 31 of the inner wall part 30 formed in the substantially perpendicular direction with respect to the advancing direction of the 1st airflow F1 It escapes from the through hole H to the internal space S1.

Here, the first air flow F1 is generated in the circulation path S2 as a result of blowing air exchanged with the refrigerant through the heat exchanger 11b by the air flow control fan 11c. Therefore, the temperature of the first air flow F1 is temperature-managed in order to maintain the temperature of the internal space S1 in the container unit 10 at the set temperature.

Thereby, as part of the temperature-controlled first air flow F1, the second air flow F2 generated by the concave portion of the concavo-convex structure 23a can be actively sent to the inner space S1 side. Therefore, the temperature management in the internal space S1 of the container unit 10 can be efficiently performed.

Moreover, since the container unit 10 of the present embodiment employs a structure that can efficiently perform temperature management by the air conditioning unit 11, the thickness of the heat insulating material 22 can be made thinner than before.

Therefore, when compared with a container unit of the same size, the container unit 10 of the present embodiment can have a larger volume of the internal space S1 than the conventional container unit. As a result, the amount of cargo loaded in the container unit 10 can be increased.

(Uneven structure 31a)
FIG. 5 is a perspective view showing the configuration of the third surface of the inner wall portion of the container unit of FIG. 1. As described above, in the container unit 10 of the present embodiment, the concavo-convex structure 31a is provided on the surface side facing the aluminum plate 23 of the outer wall portion 20, which is the third surface of the resin plate 31 constituting the inner wall portion 30. ing.

As shown in FIG. 5, the concavo-convex structure 31 a is configured by alternately and continuously arranging linear concave portions and linear convex portions.

Further, as shown in FIG. 5, the concave and convex portions constituting the concave-convex structure 31a are formed so as to extend along the flowing direction of the first air flow F1 generated by the air flow control fan 11c.

Thus, the flow of the first air flow F1 temperature-controlled by the air conditioning unit 11 is not hindered on the inner wall 30 side where the uneven structure 31a is formed. Therefore, the heat dissipation effect to the internal space S1 in the inner wall portion 30 can be improved, and the temperature of the temperature-controlled first air flow F1 can be efficiently radiated to the internal space S1 side. As a result, the efficiency of temperature management by the air conditioning unit 11 can be further improved.

In addition, in the structure of this Embodiment, since the heat dissipation effect is obtained structurally, a higher effect can be acquired by forming the uneven structure 31a etc. using the material with a high heat dissipation effect.
