The cooling system comprises a diesel engine body, a cooling water pump, an intercooler and a radiator, wherein the cooling water pump is integrated on the diesel engine body; the intercooler is fixed at a power output end of the diesel engine body; an air inlet of the intercooler is connected with a supercharger of the diesel engine body; an air outlet of the intercooler is connected with an intake pipe of the diesel engine body; the radiator is fixed at a free end of the diesel engine body; a water inlet pipe and a water outlet pipe of the radiator are respectively connected with the water inlet and the water outlet of the diesel engine body, and are also connected with a water outlet pipe and a water inlet pipe of the intercooler; and the radiator and the intercooler are symmetrical about the transverse center line of a crankshaft of the diesel engine body. The cooling system has the characteristics of compact structure, convenience for installation, stable operation, lower power consumption, low system resistance and high safety coefficient.

Description

technical field [0001] The invention relates to an integrated axially symmetrical cooling system for a water-cooled diesel engine, which belongs to the field of cooling systems for diesel engine bodies, and is especially suitable for cooling marine diesel engines. Background technique [0002] The body of a diesel engine is generally composed of a free end, a power output end and a box body. The free end refers to the end opposite to the power output end, also known as the front end, which is mainly used to install various shafting and pump transmission gears; The end of the output power is also called the rear end; the piston in the box reciprocates at high speed in the cylinder bore, which is the key part of the diesel engine body. [0003] During the working process of the diesel engine body, a large amount of heat is generated due to the combustion of fuel and the friction between moving parts, which makes the parts intensely heated. If there is no proper cooling, the n...

Problems solved by technology

[0005] Traditional supercharged diesel engines are generally of non-integrated design. The radiator and intercooler are arranged on the same side of the diesel engine body. In practical application, due to the large space occupied by the radiator and intercooler, the space occupied by the supercharged diesel engine is very large, its compactness is not enough, and the installation and construction are difficult; the radiator and intercooler will be integrated on the supercharged diesel engine later, although The compactness has been improved to a certain extent, but due to the conventional asymmetric structure, there are still many pipelines that need to be connected to the radiator and the intercooler, and the installation is still difficult. The resistance along the way increases, the power consumption is large, the system resistance is increased, and the risk of coolant leakage is increased, the safety factor is low, and the operation stability and work efficiency of the supercharged diesel engine are affected
