<p>PURPOSE:To enable arbitrary setting of a passage and enhance heat-exchanging efficiency in a limited space, by disassemblably laying corrugated projecting parts of heat-exchanging elements adjacent to recessed parts of a continuous V-shaped corrugation one over another at an appropriate pitch and providing flow-straightening means and nozzles at both ends of the assembly thus obtained. CONSTITUTION:Heat-exchanging elements 6 are laid one over another in a disassemblable manner between flow-straightening means 4 and 5. Each of the elements 6 is provided with a continuous V-shaped corrugation, and the elements 6 are laid one over another at such a pitch P that each of recessed parts 6a of the corrugation of the element 6 faces each of projected parts 6b of the corrugation of the adjacent element 6, with an appropriate gap C therebetween. By setting the pitch P to an appropriate size, the gaps C through which a low-temperature fluid or a high-temperature fluid can flow are formed between the heat-exchanging elements 6, and the flow velocity of the fluid can be controlled by the size of the gaps, so that the flow rate per unit time of the fluid can be controlled by the setting of the pitch P. The pitch P is determined by the thickness of spacers 8 and the vertical size of opening parts for assembly of the flow-straightening means 4, 5.</p> |
