Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a heat exchanger of a marine diesel engine with a vortex desanding function comprises a heat exchanger shell 1, a core, a left end cover 2 and a right end cover 3, wherein the core is arranged in the shell 1; the left end cover 2 and the right end cover 3 are both connected to the left side and the right side of the shell 1 through flanges, and the lower end of the left end cover 2 is provided with a cooling water outlet 4; a water inlet cavity 5 is arranged in the right end cover 3, and the water inlet cavity 5 is a cylindrical cavity; the upper end of the water inlet cavity 5 is provided with a cooling water inlet 6, and the lower end is provided with a water outlet 7 communicated with the core; the central part of the lower end of the water inlet cavity 5 is provided with a cleaning port 9, and the cleaning port 9 is internally threaded with a stud 10.
