Problems solved by technology
However, due to the limitation of the internal space of the engine room 11, the size of the cooling fan is limited, and the increase in the speed of the fan 14 will increase the rotation noise of the fan 14, which does not comply with the "External Noise Limits and Measurement Methods of Vehicle Acceleration" in GB1495. Regarding the regulations on vehicle noise, considering the above, the purpose of heat dissipation for the gas turbine 12 cannot be achieved by increasing the size and speed of the fan 14 infinitely. Further, the increase in the size and speed of the fan 14 will lead to energy consumption of the cooling fan. increase, resulting in a decrease in the ratio of the energy used by the gas engine 12 to drive the vehicle to the total energy of the gas engine 12

The invention relates to the technical field of vehicle cooling systems, in particular to a distributed type cooling system and method. The distributed type cooling system and method aim to solve thetechnical problems that concentrated type cooling systems are high in energy consumption and large in occupied local space. The distributed type cooling system comprises a forced cooling system and awindward cooling system which are connected between an engine water inlet pipe and an engine water outlet pipe in parallel and are distributed on an engine compartment and the windward side of a rear-engine type motor vehicle separately; a first control valve is arranged on a radiator water inlet pipe of the forced cooling system; a second control valve is arranged on a radiator water outlet pipeof the forced cooling system; a third control valve is arranged on a radiating tube water inlet pipe of the windward cooling system; and a fourth control valve is arranged on a radiating tube water outlet pipe of the windward cooling system. The distributed type cooling system can reduce the energy consumption and the occupied local space of the concentrated type cooling systems.
Description
technical field [0001] The invention relates to the technical field of vehicle cooling systems, in particular to a distributed cooling system and a distributed cooling method. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] According to statistics, only 35-45% of the fuel combustion energy in a diesel engine is output through the crankshaft as effective work, and the rest of the combustion energy is taken away by about 30% through the exhaust system, 20-30% through the coolant, and through the intercooler. About 5% is taken away, and the remaining combustion energy is consumed in different forms such as radiation and convection. Among them, the temperature of the engine coolant directly affects the temperature of various components in the engine. Generally, the temperature of the engine coolant is maintained at 75 ° C ~ 95°C is an ideal state. When the temperature of...
