Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation structure on a side wall of a cargo refrigerating compartment having a large flare, which has a plurality of decks.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 2, a device of this type has a hull outer plate 31 with a large flare between a lower deck 32 which is a heat-insulating deck and an upper deck 38 which is a grating deck in a cargo refrigerating barge 40 of a refrigerating vessel. A heat insulating material 33 is applied to the inside of the hull, and a plurality of shoring boards 37 are provided along the hull outer plate 31 slightly inside the intersection between the hull outer plate 31 on which the heat insulating material 33 is applied and the lower deck 32. Instead, it is erected between the upper deck 38 and the lower deck 32, and the triangular space 41 surrounded by the upper deck 38, the lower deck 32, the shoring board 37 and the hull outer plate 31 is isolated from the cargo refrigeration barge 40. The heat insulating material 33 is also applied on the lower deck 32, and the cold air passage 35 is formed by the wooden plywood 34 and the perforated wooden floor board 36, and the perforated wooden floor board is formed from the cold air passage 35. Pass through 36 The cold air B that enters the refrigerating barge 40 cools the cargo 42, and the cold air B that flows between the wooden floor plates 39 that are fixedly attached to the upper deck 38 with a proper spacing is used. It is known to cool the upper cargo 42.

[0003]

[Problems to be solved by the device]

 As described in the prior art, the cold wind on the hull skin side that blows out from the cool air duct flows along the shoring board and through the gaps between the wooden floor boards of the upper deck, but on the upper deck. There was a problem that the cold air did not circulate around the cargo placed on the outer skin of the hull, and the cargo on the outer skin of the hull was not cooled uniformly, resulting in cargo damage.

The present invention has been made in view of the above problems of the conventional technology, and an object of the present invention is to make it possible to evenly cool the cargo on the outer plate side of the hull on the grating deck. It is intended to provide a side wall ventilation structure for a refrigerator.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a cold wind air passage formed by heat-insulating construction on a lower deck in a cargo refrigeration compartment with a plurality of decks and a large flare, and is installed inside a hull outer plate. The heat insulating material for spraying, a plurality of shoring boards standing vertically between the upper and lower decks at intervals along the outer shell of the ship immediately before the heat insulating material for the spray heat insulating material, and the upper and lower decks. It consists of a deck, a grating deck at the upper part of a triangular space surrounded by the shoring board and the hull outer plate, and the cold air blown out from the cold air passage is in the triangular space from the gap between the shoring boards. The cooling air is circulated around the cargo on the grating deck, which is the upper deck, and the cargo is uniformly cooled.

[0006]

[Action]

 The cool air that flows through the air passages on the lower deck of the heat-insulating deck and that blows out from the holes in the perforated wooden floor boards that are the tops of the air passages flows between the shoring boards, along the hull outer plate, and above. It is distributed on the grating deck.

[0007]

【Example】

 An example will be described with reference to the drawings. As shown in FIG. 1, a heat insulating material 5 is applied on the lower deck 2 in a cargo refrigerating section 11 having a large flare having a plurality of decks, and a wooden material is applied thereon. The plywood 6 and the perforated wooden floor plate 8 form an air passage 7 for cold air.

A spray heat insulating material 4 is applied to the inside of the hull skin 1, and a plurality of shoring boards 9 are provided along the side wall immediately before the hull outer skin 1 on which the spray heat insulating material 4 is applied. After the dawn, it will be erected between the upper deck 3 and the lower deck 2.

A triangular void 12 is formed by being surrounded by an upper deck 3, a lower deck 2, a shoring board 9 and a hull outer plate 1, and the upper deck 3 which is an upper portion of the triangular void 12 is used as a grating deck. Allows ventilation.

In this embodiment, the cold air A on the side of the hull skin 1 that blows out from the cold air passage 7 enters the triangular void 12 through the gaps between the respective shoring boards 9 and is the upper deck 3. It blows out from the gap of the grating deck and cools the cargo 13 placed on the wooden floor board 10 on the upper deck 3.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. The cold wind on the hull skin side that blows out from the cold air passage distributes in the triangular space surrounded by the upper and lower decks, the shoring board, and the hull skin, so that the cargo placed on the hull skin side. The cold air circulates in the air, and the cargo on the outer plate side of the hull can be cooled sufficiently, the temperature inside the cargo refrigeration bar is uniform, and cargo damage can be prevented.
