Heat exchanger for cooling ship engines with outboard water, contains pipe bundle with pipe segment extending parallel to water surface

摘要

The heat exchanger (3) contains a pipe bundle (5) with at least one pipe segment (51-54) extending parallel to the water surface. The heat exchanger is located at least partly below the water surface and is in open communication with the outboard water (8) via openings in the ship hull. The heat exchanger comprises a connection plate for sealing the space in which it is mounted and containing at least one inlet (7a) for a coolant with a high temperature and at least one outlet (7b) for a coolant with a low temperature. At least one pipe bundle for transporting coolant between the inlet and outlet is surrounded by the outboard water.
