Cooling system of an internal combustion engine

A combustion engine, comprising:

• a compression ignition (CI) motor with at least two cylinder banks and with an identical number of cylinder banks and exhaust gas heat exchangers;
• and
• a cooling system through which a fluid flows in a preferred flow direction, the cooling system including:
• a primary section configured to be secured to a retarder;
• and
• an identical number of branch sections as the number of cylinder banks of the CI motor, and the branch sections fluidly communicate with the primary section;
• wherein each one of the branch sections has a cylinder bank branch section, a heat exchanger branch section, and a merging branch section,
• wherein the primary section ends in the cylinder bank branch sections, and each one of the cylinder bank branch sections has a branch section outlet that is in contact with fluid through a designated cylinder bank inlet;
• wherein each one of the heat exchanger branch sections comprises a branch section inlet of the exhaust gas heat exchanger and a branch section outlet of the exhaust gas heat exchanger, and each one of the heat exchanger branch sections is in contact with fluid through a designated cylinder bank outlet and each one designated exhaust gas heat exchanger inlet;
• wherein each one of the merging branch sections has a merging branch section inlet, and each one of the merging branch sections is in contact with fluid by an exhaust gas heat exchanger outlet, and each one of the merging branch sections is furthermore in contact with fluid through the primary section in the preferred flow direction downstream from the merging branch section inlets.

A cooling system for a combustion engine comprising a compression ignition motor, the cooling system comprising:

• a primary section configured to be secured to at least one retarder;
• a plurality of branch sections disposed in parallel and fluidly communicating with the primary section, such that a fluid serving as coolant flows through the cooling system in a preferred flow direction wherein the number of branch sections is identical to a number of cylinder banks of the compression ignition motor;
• and
• an identical number of exhaust gas heat exchangers as the number of cylinder banks, and each one of the exhaust gas heat exchangers is disposed in a corresponding one of the branch sections;
• wherein each one of the branch sections has a cylinder bank branch section, a heat exchanger branch section and a merging branch section;
• wherein each one of the cylinder bank branch sections fluidly communicates with a cylinder bank inlet of a corresponding cylinder bank, such that each one of the cylinder bank branch sections is configured to direct fluid from the primary section to a corresponding one of the cylinder banks;
• wherein each one of the heat exchanger branch sections includes a branch section outlet of the cylinder bank and a branch section inlet of the exhaust as heat exchanger, such that each one of the heat exchanger branch selections is configured to direct fluid from a corresponding cylinder bank to a corresponding exhaust as heat exchanger;
• wherein each one of the merging branch sections fluidly communicates with an exhaust as heat exchanger outlet and the primary section, such that each one of the merging branch sections is configured to direct a parallel partial coolant flow flowing through the corresponding exhaust as heat exchanger to the primary section;
• and
• wherein the merging branch sections combines each of the parallel partial coolant flows upstream of the primary section such that an extraction of coolant from the primary section evenly affects the partial coolant flows of the exhaust as heat exchangers.
