PURPOSE:To prevent a fluid to be cooled in a heat exchanger from flowing out from a space between a shell and a tube bundle by short circuiting, by sealing between a tube bundle side partition plate and a front and a rear partition plates by a short circuit prevention plate which joined plates having different thermal expansion coefficients. CONSTITUTION:A short circuit prevention plate 12 which joined two kinds of metals 12a and 12b having different thermal expansion coefficients is installed on a front and a rear partition plates 5 and 6, and a side of the metal having a smaller thermal expansion coefficient of the short circuit prevention plate 12 is made to touch to a partition plate 9 on a tube bundle side. The short circuit prevention plate 12 is made to bend to the side of the tube bundle 9 for deformation through a thermal expansion difference between metals 12a and 12b, and the short circuit prevention plate 12 is adhered closely to the tube bundle partition plate 9. |
