A cuboid pressure vessel comprises a top wall, a bottom wall, and an external wall. The external wall comprises a main body including a first side wall having a first opening, and a second side wall having a second opening; a first lid secured to the first side wall so as to occlude the first opening; and a second lid secured to the second side wall so as to occlude the second opening. The bottom wall comprises a main body; and a reinforcement rib provided in an upright manner on the outer surface of the main body. The reinforcement rib is provided in an upright manner on the outer surface of an area, within the main body, which contains a central section of the main body, and which excludes four corner sections, a region adjacent to the first lid and a region adjacent to the second lid.

1. A cuboid pressure vessel, comprising: a square-shaped top wall;a square-shaped bottom wall which is opposed to the top wall; andan external wall which connects the periphery of the top wall to the periphery of the bottom wall, whereinthe external wall is provided with: an external-wall main body
1. A cuboid pressure vessel, comprising: a square-shaped top wall;a square-shaped bottom wall which is opposed to the top wall; andan external wall which connects the periphery of the top wall to the periphery of the bottom wall, whereinthe external wall is provided with: an external-wall main body which includes a first side wall having a first opening that allows a heat exchanger to be inserted to an area surrounded by the external wall, and a second side wall having a second opening that allows the heat exchanger to be inserted to the area surrounded by the external wall; a first lid which is configured to cover the first opening and which is secured to the first side wall so as to occlude the first opening; and a second lid which is configured to cover the second opening and which is secured to the second wall so as to occlude the second opening, where the size of the first opening is such that the first opening does not extend to substantially cover an entire area of the first side wall and the size of the second opening is such that the second opening does not extend to substantially cover an entire area of the second side wall;the bottom wall is provided with: a bottom-wall main body which is connected to the lower end of the external wall; and a bottom-wall reinforcement rib which is provided in an upright manner on the outer surface of the bottom-wall main body, andthe bottom-wall reinforcement rib is provided in an upright manner on the outer surface of an area, within the bottom-wall main body, which contains a central section of the bottom-wall main body and which excludes four corner sections, a region adjacent to the first lid, and a region adjacent to the second lid of the bottom-wall main body such that the outer surfaces of the four corner sections, the region adjacent to the first lid and the region adjacent to the second lid of the bottom-wall main body have no ribs and are substantially flat. 2. The pressure vessel according to claim 1, wherein each of the corner sections has a square shape having a side containing each vertex of the bottom-wall main body and having the same dimension as the height dimension of the external wall as each side, the region adjacent to the first lid has a square shape having a portion which has a length corresponding to the first lid, within the peripheral edge on the first side-wall side of the bottom-wall main body, as a first side; and a portion which is extended from an end of the first side in a direction orthogonal to the first side by the same dimension as the height dimension of the external wall as a second side, andthe region adjacent to the second lid has a square shape having a portion which has a length corresponding to the second lid, within the peripheral edge on the second side-wall side of the bottom-wall main body, as a first side; and a portion which is extended from an end of the first side in a direction orthogonal to the first side by the same dimension as the height dimension of the external wall as a second side. 3. The pressure vessel according to claim 1, wherein the pressure vessel further comprises: a first lower reinforcement portion and a second lower reinforcement portion for reinforcing the boundary between the external-wall main body and the bottom-wall main body;the external-wall main body is provided with: a third side wall different from the first side wall and the second side wall; and a fourth side wall different from the first side wall, the second side wall and the third side wall,the first lower reinforcement portion is provided on the inner surface side of the third side wall and the bottom-wall main body within the boundary between the third side wall and the bottom-wall main body, andthe second lower reinforcement portion is provided on the inner surface side of the fourth side wall and the bottom-wall main body within the boundary between the fourth side wall and the bottom-wall main body. 4. The pressure vessel according to claim 3, wherein the top wall is provided with a top-wall main body which is connected to the upper end of the external wall, and a top-wall reinforcement rib which is provided in an upright manner on the outer surface of the top-wall main body,the first side wall and the second side wall are opposed to each other, and the third side wall and the fourth side wall are opposed to each other, andthe external wall is further provided with: third side-wall reinforcement ribs which are provided in an upright manner on the outer surface of the third side wall and which are configured to extend throughout the whole area in the height direction of the third side wall and to connect to the top-wall reinforcement rib and the bottom-wall reinforcement rib; and fourth side-wall reinforcement ribs which are provided in an upright manner on the outer surface of the fourth side wall and which are configured to extend throughout the whole area in the height direction of the fourth side wall and to connect to the top-wall reinforcement rib and the bottom-wall reinforcement rib.
