Description

Technical Field

[0002] Heat exchangers are one of the indispensable and important equipment widely used in ship engines. At present, an O-ring is provided between the water inlet end cover and the shell of a water-type heat exchanger, so as to seal seawater from flowing out from the end face, seal fresh water from flowing out from the end face, and seal seawater and fresh water from flowing into the cavity, thereby effectively sealing the heat exchanger.
