Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation device using a plurality of hatch covers.

Conventionally, when transporting refrigerated containers by ship, refrigerated containers 2 are stacked on a hatch cover 1 as shown by the solid line in FIG. The reason is,
This is because it is convenient for naturally dissipating heat emitted from the heat dissipation section 3 of the refrigerator of the refrigerated container 2 into the atmosphere. However, as a recent trend, the number of locations where refrigerated containers 2 must be transported has increased, and it has become necessary to store refrigerated containers 2 also in the hold 4, as shown by the imaginary line in FIG.
However, if you do so, the refrigerated container 2 in the hold 4
The only way to dissipate the heat from the heat dissipation section 3 is to dissipate it into the atmosphere through the narrow space between the hatches on the upper deck.
A problem arises in that it hits the upper freezer container 2 and heats it up. Therefore, it is conceivable to form a ventilation passage inside the hatch cover and dissipate the heat to the atmosphere through the ventilation passage, but in a ship that has multiple hatch covers independently from each other along the transverse direction of the hull, each hatch cover A problem arises in that the heat radiated from the sides other than the side surfaces of the hatch hits the refrigerated container 2 on the hatch cover 1 and heats it.

The present invention provides a ventilation device that uses a plurality of hatch covers that solves this problem.The present invention is characterized by providing a first ventilation port that communicates with the inside of a ship's hold at a suitable location on each hatch cover, and A communication port is formed on each side of the hatch cover that faces each other, and a communication cylinder is provided to communicate between the communication ports that are opposed to each other.A second communication port is provided on the outer side of the hatch cover near the gunwale, and a A ventilation passage is provided from the first ventilation opening to the second ventilation opening through the inside of the communication cylinder. According to this configuration, the air in the hold is passed through the ventilation passage in the hatch cover and the inside of the communication cylinder, and the air is transferred to the side of the ship. It can be dissipated into the atmosphere from the outside side of the hatch cover, which is close to the air. Therefore, it is possible to solve the problem that, for example, heat dissipated from inside the ship's hold through the ventilation passage in the hatch cover hits the refrigerated container on the hatch cover and heats it.

An embodiment of the present invention will be described below with reference to FIG. 2 and subsequent figures.
