PVC soft fabric is one of the thermoplastics, also called polyvinyl chloride or vinyl chloride resin, and can be abbreviated as PVC. PVC soft fabric is a plastic based on vinyl chloride and can be processed into a wide range of products such as films, sheets, molded products, and caps. The typical PVC of plastic is originally a material having a hard property, but can be commercialized after increasing flexibility and elasticity by using a phthalic acid-based or adipic acid-based plasticizer. Windproof vinyl is a vinyl produced using soft PVC, and is made of a thin material, so it has high flexibility and elasticity, so it can have properties that can be expanded by wind. The soft polyurethane foam may mean a polyurethane foam having soft properties. Polyuritan foam is a porous material in a sponge state made of polyol and isocyanate used as a cushioning material and insulation material, and has high insulation properties, excellent electrical insulation properties, and high strength. The soft materials described above are merely examples, and the present disclosure is not limited thereto.

The cold air jetting duct 520 made of a soft material may be inflated by the pressure of the cold air supplied from the cooling unit 300 and then jet cold air. At this time, after the cold air jet duct 520 made of a soft material is expanded, the flow rate of cold air coming from each cold air jet duct 521 comes out from each cold air jet duct 521 of the cold air jet duct 520 made of a hard material. When compared to the flow rate of cold air, it can be distributed more evenly. More specifically, when the cold air jetting duct 520 is made of a soft material, an effect that the air flow rate of each cold air jetting port 521 is the same may occur.

According to one embodiment of the present disclosure, the cold air jet duct 520 may be fixed by being coupled to a fastener located on the inner wall of the outer wall 110 to be detachable. More specifically, the end of the cold air jet duct 520 may be fixed by being coupled to a fastener located on the ceiling wall so as to be detachable. In addition, one or more fasteners located on the side surface of the cold air jet duct 520 may be fixed by being detachably coupled with one or more fasteners located on a part of the inner fixing device of the container 1000. The fixing device may be, for example, a shelf that fixes the frozen food immovably or a battery rack 200 that fixes the battery module. The fastening position of the aforementioned cold air jet duct 520 is only an example, and the present disclosure is not limited thereto.

The fastener may be connected to at least one of an annular structure, a velcro structure, or a zipper structure. The annular structure may be a method of fixing the cold air blowing duct 520 by combining a ring connected to the cold air blowing duct 520 with a ring of a fastener.

The zipper structure is a closing tool made of two tape strands with teeth on the edges, and the teeth can be engaged with each other in a slide manner to fix the cold air jet duct 520 to the fastener. The above-mentioned types of fasteners are only examples, and the present disclosure is not limited thereto.

6 is a battery rack 200, a cooling unit 300, an air outlet 400, a cold air delivery duct 510, a cold air jet duct 520 provided inside the container 1000 according to the first embodiment of the present disclosure. And an enlarged view of the cold air spout 521.

According to an embodiment of the present disclosure, the cold air delivery duct 510 may include one or more cold air jet ports 521. One or more cold air blowing ports 521 may be provided in the cold air delivery duct 510 to serve as a passage through which cold air is blown into the air around the cold air blowing duct 520.

The shape of the cold air outlet 521 may be one of circular, elliptical, or polygonal. When the cold air jet port 521 is in a circular shape, the cold air may be spread in a cone shape while being jetted. When the cold air jet port 521 has a thin and elongated oval shape in the vertical direction, the cold air may be continuously transferred to the load loaded inside the container 1000 present at the position of the ellipse.

When the cold air jet port 521 faces the direction in which the object is located, when cold air is directly blown into the object, an effect of controlling heat generation in a faster time may occur.

According to another embodiment of the present disclosure, the cold air outlet 521 may be provided to correspond to at least a portion of a layer in which a battery module is present among the battery racks 200 storing batteries when the loaded object is a battery. . When the cold air jet port 521 is provided to correspond only to the layer where the battery module is present, the cold air flow rate per each cold air jet port 521 increases, so that the flow rate directly discharged to the battery module increases, thereby more efficiently generating heat of the battery module. Can be controlled.

According to another embodiment of the present disclosure, the cold air jet port 521 may be opened or closed. For example, some of the plurality of cold air jet ports 521 may be sealed. In this case, since the flow rate of the cold air per the open cold air jet port 521 increases, it is possible to obtain an effect of strongly controlling the wind strength of the open cold air jet port 521. On the contrary, when opening the previously sealed cold air jet port 521, an effect of weakly controlling the wind strength of the open cold air jet port 521 can be obtained.

According to another embodiment of the present disclosure, the size of the cold air jet port 521 may be adjusted.
