    摘要： The invention relates to a thermal management method for operating a thermal management system (100, 102) of an internal combustion engine (10). The thermal management system (100, 102) comprises at least one fluid chamber (12) which is arranged at least partially around a cylinder head (74) of a cylinder (70) of the internal combustion engine (10) and has at least one inlet line (14) and at least one outlet line (16), the fluid chamber (12) being connected to at least one coolant pumping device (20) for pumping a coolant, and to at least one heat sink. According to the invention, a cylinder head temperature sensor and/or a fluid chamber temperature sensor (58) is provided, a volume flow of the coolant delivery device (20) being controllable depending on an engine speed and/or a fluid chamber temperature and/or an engine load, in particular by actuation of at least the first valve (18). According to the thermal management method, when the temperature in the fluid chamber (12) rises, in particular after a warm-up phase and when the engine speed remains constant or drops, the volume flow of the coolant through the heat sink is at least temporarily increased, and when the engine speed remains constant or increases by no more than 100 rpm, with engine load being reduced, in particular by at least 30%, the volume flow of the coolant through the heat sink is not reduced, and in particular is not reduced after at least one minute following the load change, and more particularly is not reduced when a fluid chamber (12) temperature is in the 60 to 100° C. range.

    摘要： A cooling apparatus includes a coolant passage provided in a device to be cooled. The coolant passage is configured in such a manner that coolant passes through the coolant passage. The coolant passage includes a wall surface, first ribs, and second ribs. The first ribs and the second ribs are provided on at least a part of the wall surface. The first ribs protrude from the wall surface toward inside of the coolant passage and extend in a first direction. The second ribs protrude from the wall surface toward the inside of the coolant passage and extend in a second direction crossing the first direction. The first ribs and the second ribs are disposed alternately when viewed in at least one direction.

    摘要： The invention relates to a thermal management method for operating a thermal management system (100, 102) of an internal combustion engine (10). The thermal management system (100, 102) comprises at least one fluid chamber (12) which is arranged at least partially around a cylinder head (74) of a cylinder (70) of the internal combustion engine (10) and has at least one inlet line (14) and at least one outlet line (16), the fluid chamber (12) being connected to at least one coolant pumping device (20) for pumping a coolant, and to at least one heat sink. According to the invention, a cylinder head temperature sensor and/or a fluid chamber temperature sensor (58) is provided, a volume flow of the coolant delivery device (20) being controllable depending on an engine speed and/or a fluid chamber temperature and/or an engine load, in particular by actuation of at least the first valve (18). According to the thermal management method, when the temperature in the fluid chamber (12) rises, in particular after a warm-up phase and when the engine speed remains constant or drops, the volume flow of the coolant through the heat sink is at least temporarily increased, and when the engine speed remains constant or increases by no more than 100 rpm, with engine load being reduced, in particular by at least 30%, the volume flow of the coolant through the heat sink is not reduced, and in particular is not reduced after at least one minute following the load change, and more particularly is not reduced when a fluid chamber (12) temperature is in the 60 to 100° C. range.

    摘要： An engine includes: an engine block including a cylinder block and a head block, a cool liquid cooler that cools a first cool liquid that cools the engine block, a lubricant oil cooler that cools a lubricant oil using the first cool liquid or a second cool liquid, an exhaust manifold mounted to the engine block, a turbocharger driven by exhaust gas from the exhaust manifold, an exhaust communication pipe that communicates the exhaust manifold with the turbocharger, and a cool liquid flow channel through which a cool liquid discharged from the engine block flows in an order of the exhaust communication pipe and the exhaust manifold. The cool liquid cooler and the lubricant oil cooler are so placed as to be arranged side by side on one end side in a crankshaft direction.

    摘要： A system includes an engine defining a water jacket fluidly coupled to a heat exchanger. An exhaust manifold defines an exhaust manifold cooling passage. A pump is fluidly coupled to the water jacket, and to each of the heat exchanger and the exhaust manifold cooling passage. An engine cooling circuit includes the water jacket, the heat exchanger, and the pump. An exhaust cooling circuit is selectively fluidly coupled to the engine cooling circuit. The exhaust cooling circuit includes the water jacket, the exhaust manifold cooling passage, and the pump. A control valve includes an inlet fluidly coupled to a first portion of the water jacket. A first outlet is fluidly coupled to a second portion of the water jacket. A second outlet is fluidly coupled to the exhaust cooling circuit. The control valve is structured to selectively control flow of coolant fluid through the second outlet.
