Abstract (en)

[origin: JPH0359397A] PURPOSE: To improve heat exchange characteristics, by connecting tubes of a tube bundle through fins each having an opening and disposed laterally with respect to the tube bundle. CONSTITUTION: Pipes 1 of a heat exchanger are disposed parallely in a housing 2, and are connected with each other through fins 5. The fin 5 is disposed laterally with respect to the pipe 1, and has an opening 6, through which opening 6 a cooling medium flowing around the pipe 1 passes from the fin to the fin. Flame pipe gas or a heat fluid enters the heat exchanger through an insertion inlet 9 and is distributed on the pipe 1 through a header 8. The flame pipe gas or fluid emanating the pipe is recovered with a header 8a and passes through an outlet 10. Produced condensate is discharged from the header 8a through a condensate derivation outlet 11. A cooling medium enters the heat exchanger through the insertion inlet 3 and discharged from the heat exchanger through the derivation outlet 4.
