摘要：This article takes the diesel thermal system as the research object, which simplifies the diesel engine system into four subsystems. This article conducts a thermodynamic analysis of the specific equipment of the host thermal system. Simulink tools in MATLAB are used to build simulation models of specific equipment in the thermal system, and a modular model is used to build a subsystem model based on the specific equipment model. Then, the thermal coupling relationship between the subsystems is used to form the thermal system. The overall model obtains the temperature values of the key nodes of the thermal system network, so that it can predict the temperature changes of the thermal pipeline system nodes of the diesel engine under various operating conditions.
