MULTITUBULAR CYLINDRICAL SINGLE-PATH HEAT EXCHANGER WHERE MULTITUBE HOLDING HEAT TRANSFER TUBE WITH TWO OR MORE STEEL PLATES AND BOTH-END CONNECTION PARTS OF TRUNK CYLINDER ARE MOLDED WITH HARDENING RESIN

摘要

PROBLEM TO BE SOLVED: To provide a multitubular cylindrical single-path heat exchanger with high tube density and high performance, where single-path heat transfer tubes mounted with a heat transfer enhancement element is installed in a trunk cylinder with high density.;SOLUTION: Mesh holes the number of which exceeds the number of tubes of a high-density tube bundle are provided, heat transfer tubes are held by two or more mesh plates having a diameter just fitted into an inner diameter of a trunk cylinder, and then inserted into the trunk cylinder, and then both end parts are fixed by hardening resin instead of a tube plate to thereby cut off both pieces of fluid. Also, in the heat transfer tube, a three-dimensional wire element is mounted such that many loop-like wires are attached to a core wire, and a tip of a loop contacts with an inner wall of the heat transfer tube.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
