PURPOSE:To permit heat exchange, prominent in durability as well as anticorrosion and efficient, by a method wherein a pipeline is supported in penetrating holes loosely by a sealing material such as a heat resistant elastic material and the like while a curved tube, positioned at the lowermost position, is supported movably from the lower side thereof in the passage of the tube. CONSTITUTION:The ends 11a, 11b of a vertical tube are connected to an inlet side pipeline 13 and an outlet side pipeline 14 through bent tubes 12a penetrating through penetrating holes 22, 23, bored on a passage wall 21, and the pipelines 13, 14 are supported movably in the penetrating holes 22, 23 through sealing materials 24, 24, such as a heat resistant elastic material or the like, while a curved tube 12, positioned at the lowermost part, is supported movably from the lower side thereof by a supporting table 15 and the like. Heat exchange between fluid, coming from a high- temperature waste heat source and flowing through the passage 20, and waste heat retrieving fluid, flowing through a heat exchanging element 10, through heat transfer tubes 12, 12, consisting of simple straight tubes and curved tubes, may be effected with a high heat transfer efficiency since a heat transfer area is increased. On the other hand, the heat exchanger can be elongated and contracted freely in three- dimensional sizes, therefore, the elongation and contraction of the heat exchanger upon thermal expansion and contraction may be adsorbed properly and surely. |
