<p>PROBLEM TO BE SOLVED: To provide a radiator of a pipe structure, which is adaptable to all the fashion of installation with a single radiator, thereby to reduce all the cost relating to manufacture and storage of the radiator. SOLUTION: In this radiator, pipe joints are configured to at least two adjacent sides, inlet and outlet joints 7, 8 respectively on the first side are connected by the first connection pipe 9, and inlet and outlet joints 11, 12 on the second side are connected by the second connection pipe 13. When either one of the connection pipes is closed by a closing plug 14 placed in the relevant connection pipe through the adjacent joint, and the connection between a connection pipe and a joint on the second side is closed, then heated liquid flows from the inlet joint 7 on the first side into a pipe structure 1, and then through the second connection pipe into the outlet joint 8 on the first side. On the other hand, when the connection between the second pipe on the second side and the joint on the first side is closed, the heated liquid flows from the inlet joint 11 on the second side through the first connection pipe into the pipe structure, then to the outlet joint 12 on the second side.</p> |
