Claims

[Scope of utility model registration request]

A large number of straight heat exchanger tubes are supported between the upper and lower tube plates in the main body, and the primary fluid flows from the upper tube plate to the lower tube plate through the heat exchanger tubes, and is opened at the upper part of the lower tube plate. In a heat exchanger, a secondary fluid introduced to an outside position in the main body shell through an inlet port is led out to the outside of the main body shell through an outlet opening at the bottom of the upper tube plate, from the inlet port to the outlet port. A heat exchanger characterized in that a helical baffle is provided between the helical baffles, and rectifying fences are appropriately arranged within the main body shell for causing the secondary fluid flowing along the helical buffles to flow in the radial direction.
