The present invention is applied to internal combustion engines installed in ships that are actively moving, and the exhaust pipe of the internal combustion engine is cooled in order to suppress heating of the engine room due to the exhaust pipe as much as possible. This reduces the temperature rise in the engine room, and uses the heat of the cooling water to heat lubricating oil, etc., thereby shortening the warm-up time and allowing immediate operation of the internal combustion engine. It is something to do.

転条件を常に選択することができるものである。In the present invention, the inner shell 14 is made of a material with good thermal conductivity,
By attaching the fins 14' on the inside or outside, the cooling water is further warmed by the exhaust gas, so the temperature of the cooling water is raised, but the outer shell is sufficiently insulated to have a structure with poor thermal conductivity. This prevents the temperature of the heated cooling water from dropping and prevents the temperature rise in the engine room. The cooling water that has gained heat is circulated and is partially cooled by seawater in the cooling water cooler 18, and is directly supplied to the cooling water chamber 11 of the engine with optimum humidity.
Or the cooling water chamber of the engine via the lubricating oil tank 22.
By introducing the cooling water into 4-11, the temperature of the cooling water at the extraction part can be obtained. In addition, when the engine is started, the cooling water is warmed by the exhaust gas, so the entire cooling water system can be warmed up more quickly than before, and heating shortens the operating time and maintains the Ji'F operating state. In addition, the automatic temperature control valve 17 allows the optimal operating conditions to be selected at all times since a cold water cooler 18 that is heated to seawater is provided in the circulation pipe.

効果がある。As is clear from the above description, the present invention provides an exhaust gas pipe for an internal combustion engine with a double shell structure, the outer shell of the double shell has a structure with poor thermal conductivity, and the inner shell has a Q structure with high thermal conductivity. A cooling water chamber is formed between the inner and outer legs, and a cooling water circulation system is established by connecting it to the cooling water chamber of the TA leap, which suppresses the temperature rise in the engine room due to exhaust gas and allows warm-up operation using the heat of exhaust gas. This saves time and allows ships to operate more quickly. Especially when it is desired to load up an engine quickly in a cold region, it usually takes a considerable amount of time for the engine's cooling water and lubricating oil concentration to rise sufficiently to allow the engine to be loaded. The present invention solves all of these problems at once, and has the effect of significantly reducing energy consumption compared to conventional systems that require separate fuel and electric power for warm-up.
