Description

technical field [0001] The invention relates to the technical field of automobile air intake, and provides an automatic calculation device and method for a target air intake of an automobile radiator. Background technique [0002] The engine provides power for the car and is the heart of the car. The operating temperature of the engine affects the power, economy and service life of the car. Therefore, a cooling system is needed to ensure that the engine works in an optimum temperature range. Generally, the cooling system of a car is mainly water-cooled. The radiator is the heat exchange part of the cooling system. It exchanges heat through the air volume generated during the driving of the car and the fan suction process and the coolant flowing through the engine, and the heat generated by the engine combustion is carried to the cooling system. Go, achieve cooling of the engine. [0003] In the development process of the whole vehicle, it is often necessary to determine th...

Problems solved by technology

[0004] At present, in the process of automobile design, there are usually two methods to determine the target air volume of the radiator. One is to conduct simulation calculations through 3D CFD simulation technology. There is no specific digital model in the early stage of the project, and this method can only use the digital model of an approximate model. , and it takes a long time for modeling and analysis, the workload is heavy, and the analysis period is long, which leads to an increase in project cost and a prolonged period

Another method is to use one-dimensional thermal management analysis software, which can save time and effort to calculate the target required air volume of the car radiator, but it requires sufficient professional knowledge and software application knowledge, so it is very inconvenient for early-stage designers to use
