Detailed Description
As shown in fig. 1, the invention proposed by the invention proposes an air cooling system for an engine of a marine vessel, which comprises a first shell 1, a second shell 2, an air pump 3, a water pump 4, a rotating shaft 5, a first sealing assembly 6 and a second sealing assembly 7, wherein the first shell 1 is arranged on a shell of an engine 12 to form an interlayer 8 between the first shell 1 and the shell of the engine 12, the first shell 1 is provided with an air inlet and an air outlet, the second shell 2 is provided with a chamber 9, the chamber 9 is provided with an water inlet and a water outlet, a first end and a second end of the rotating shaft 5 both penetrate through the chamber 9 and are rotatably connected with the chamber 9, the rotating shaft 5 and the second shell 2 are dynamically sealed, the rotating shaft 5 in the chamber 9 is sleeved with heat conducting fins 10, the first end is rotatably connected with the first sealing assembly 6 and is dynamically sealed with the first sealing assembly 6, the second end is rotatably connected with the second sealing assembly 7, and with second seal assembly 7 dynamic seal, first end or second end are equipped with the belt pulley 11 that passes through belt drive with engine 12 and is connected, pivot 5 has the air flue 13 that extends to the second end by first end, establish first chamber 14 that holds in first seal assembly 6, establish the second in the second seal assembly 7 and hold chamber 15, but first chamber 14, air flue 13, second hold between chamber 15, air pump 3, the intermediate layer 8 and air cycle, but between water inlet, water pump 4, cavity 9, the delivery port water cycle. A sealing ring is arranged between the rotating shaft 5 and the second shell 2. The first housing 1 is fixedly connected with the second housing 2.
The engine 12 generates heat during operation and conducts the heat to the outer shell of the engine 12, the outer shell of the engine 12 exchanges heat with the air in the interlayer 8, the air pump 3 circulates the hot air in the interlayer 8 to the air passage 13 of the rotating shaft 5, the air passage 13 exchanges the heat to the water in the cavity 9 through the heat conducting fins 10 and the rotating shaft 5, because the rotating shaft 5 is driven to rotate when the engine 12 is operated, theoretically, the greater the output power of the engine 12 is, the more the engine 12 heats, the faster the rotating shaft 5 rotates, the faster the heat exchange between the hot gas in the air passage 13 and the water in the chamber 9 is, the more heat is taken away from the engine 12 during the air circulation process, therefore, the temperature of the engine 12 is reduced to the maximum extent, the engine 12 can run more safely and efficiently with low loss, and the water pump 4 guides the water in the chamber 9 out of the chamber 9 for cooling, so that the continuous temperature reduction of the engine 12 is realized.
