Title: Heat exchanger
Inventor: TAKAHASHI HIROSHI
IPC: F04D29/58
Filed: 1982-01-22
Abstract: PURPOSE:To prevent leakage of a fluid from a flowpath shortcircuiting preventive part provided between three members, that is, inlet side, outlet side and tube nest of the shell, to improve the cooling effect and prevent lowering of efficiency of compressor and the like by providing a cooling mechanism in a flowpath shortcircuiting preventive part in the heat exchanger used in a turbo type multistage compressor or the like. CONSTITUTION:Front and rear partition plates 5 and 6 are mounted on the inner wall of the shell 1, and a tube nest side partition plate 13 is also mounted on a tube nest 4. A shell side partition plate 14 is fitted to the front and rear partition plates 4 and 5. The partition plate 14 is provided at the upper part of the tube nest side partition plate 13 by maintaining a slight gap therewith in an opposing manner. The above described tube nest side partition plate 13 and the shell side partition plate 14 are provided with recesses 15 and 16, respectively. A flowpath shortcircuiting preventive part 12 is constituted by the tube nest side partition plate 13 and the shell side partition plate 14. Through this procedure, when a fluid to be cooled at the inlet side of the shell 1 which is not cooled yet has a high temperature, leaks from the flowpath shortcircuiting part 12, this fluid to be cooled, which has already leaked, is cooled by cooling water flowing through cooling tubes 17a and 17b. Therefore, the temperature of this fluid becomes identical to the temperature of the fluid at the tube nest outlet side which has flowed through the tube nest 4 and has been cooled. That is, since the fluid to be cooled, which is not cooled yet and has a high temperature, does not directly flow into the tube nest outlet part, an effect the same as that of completely preventing leakage of the fluid by the flowpath shortcircuiting part 12, can be achieved.
