- Each heat exchange unit 10 has an inflow passage 13 at one end thereof and an outlet passage 14 at the other end thereof.
- the inflow passage 13 and the outflow passage 14 communicate with the oil passage 15.
- the inflow passage 13 and the outflow passage 14 of each heat exchange unit 10 are connected in communication with each other.
- the upper plate 11 has an upper flange 23 protruding upward from the upper portion of the inlet passage 13 and the outlet passage 14, and the lower plate 12 has an inlet passage 13 and an outlet passage 14. It has a bottom flange 24 that projects downward from the bottom.
- the upper flange 23 and the lower flange 24 of the adjacent heat exchange units 10 are fitted to each other to ensure the sealing property.
- the fitted upper flange 23 and the lower flange 24 may be sealingly coupled through brazing or the like.
- the inflow passage 13 and the outflow passage 14 of the heat exchange unit 10 are closed with respect to the cooling water passage 28.
- an inlet cap 25 having an inlet 25a is coupled to the upper flange 23 of the uppermost heat exchange unit 10, and an outlet cap 26 having an outlet 26a is connected to the other upper flange 23.
- the closing holes 27 may be prefabricated or integrally formed on both lower flanges 24 of the lowermost heat exchange unit 10, respectively.
- the outer diameter surface of the upper flange 23 is fitted to the inner diameter surface of the adjacent lower flange 24.
- the outer diameter surface of the lower flange 24 may be fitted to the inner diameter surface of the adjacent upper flange 23.
- the upper flange 23 of the other heat exchange unit 10 fitted to the inner diameter surface of the lower flange 24 of the one heat exchange unit 10 may have its upper end 23a tapered in the inner diameter direction.
- the lower flange 24 may have its lower end 24a tapered in the inner diameter direction.
- the flanges fitted to the inner diameter surface of the flange of the adjacent heat exchange unit among the flange of one side heat exchange unit is characterized in that the end (23a, 24a) is tapered in the inner diameter direction.
