Modern cooling is one of the issues of interest to engineers of the internal combustion engine. This cooling system is used in a variety of ways, such as precise cooling, intelligent cooling, ... in the industry. One of the focal points in the field of cooling improvement is the adjustment of the flow rate required by the pumps. At present, in conventional conventional cooling systems, the pumps used are only a function of the distance, while one of the factors affecting engine cooling is. In this thesis, it is attempted to see, in addition to the effects of the engine load on the cooling current. The goal is ultimately to extract the required flow in terms of the load and the engine speed and draw a three-dimensional map in terms of load and distance. The stages of the project are such that at first a complete geometry of a TC EF7 engine is considered, then the thermal and fluid boundary conditions are obtained at different times and loads for the national engine using the GT-Power software. Then, flow and heat solving is done by Fluent software to extract the temperature at different points of the engine and with different fluxes to determine the critical and non-critical points. Finally, it attempts to determine the required flow temperature and coolant temperature with the critical points of the engine operation in different times and times. Finally, with the assumption of boiling in problem solving, it is observed that by keeping the wall temperature in an optimal amount, with increasing engine speed and load, the coolant flow rate from the wall or the required flow must be increased.
