| (54) | Heat exchanger and nozzle of heat exchanger |
| (57) In one embodiment, a heat exchanger (10) is provided with an inside shell (12), an
outside shell (11), a cooling portion, and an inlet nozzle (19). The inside shell
(12) has an inside space for flowing a fluid (S), and an opening portion (12a) for
outflowing the fluid (S) from the inside space. The outside shell (11) covers the
inside shell (12) to form a first passage (17) between them to flow the fluid (S)
outflowing from the opening portion (12a). The cooling portion is disposed within
the inside shell to cool the fluid (S) within the inside space. The inlet nozzle (19)
has an inner pipe (20), an outer pipe (21), and an outlet pipe (22). The inner pipe
(20) flows the fluid into the inside space through the outside shell (11). The outer
pipe (21) covers the inner pipe (20) to form a second passage (23) between them and
has its one end connected to the outside shell (11) to communicate the second passage
(23) with the first passage (17), and its other end connected to the inner pipe (20)
on the outside of the outside shell (11) to seal the second passage (23) to flow the
fluid (S) partly from the first passage (17) to the second passage (23). The outlet
pipe (22) is connected to the outer pipe (21) to inflow the fluid (S) from the second
passage (23).
