Background

The tube sheet type air cooler is widely applied to various supercharged engines as a supercharged air cooler; the working principle is that high-temperature pressurized air flows through the cooling fins, heat is transferred to the outer wall of the cooling pipe through convection, then transferred to the inner wall of the pipe through heat conduction of the outer wall of the pipe, and then the heat is taken away through convection of cooling water in the pipe, so that the heat exchange process is completed.

In the prior art, the main components of the segment air cooler comprise: cooling tubes, cooling fins, side plates, tube plates, end covers, various sealing components and the like; the cooling tube is expanded and connected to the corresponding tube plate by the tube expander, the radiating fin is attached to the outer wall of the cooling tube by the tube expander, and the end cover, the tube plate and the side plate are sequentially fastened and connected by bolts; the end cover at one end of the cooling pipe and the tube plate form a water inlet chamber, and the end cover at the other end of the cooling pipe and the tube plate form a water outlet chamber.

In the running process of the segment air cooler, the compressed high-temperature high-pressure air is heated and then the temperature of the segment air cooler is increased.
