Abstract

The invention relates to a radiator heat exchange performance simulation method and system. The method comprises the following steps of: obtaining parameter information of a radiator, acquiring working condition point setting information of the radiator heat exchange performance wind tunnel test; calculating the hydraulic diameter of the substance participating in the heat exchange experiment under each working condition point; heat exchange feature length, a Reynolds number and a Prandtl number; the hydraulic diameter under each working condition point is calculated; heat exchange feature length, inputting the Reynolds number and the Prandtt number into a pre-constructed mathematical model for fitting the heat exchange power of the radiator related to fluid flow; the method comprises thesteps of obtaining a mathematical model of a radiator, obtaining fitting heat exchange power, obtained through calculation of the mathematical model, of the radiator under all working condition points, optimizing the mathematical model with the minimum error between the fitting heat exchange power and actually-measured heat exchange power as a solving target, and simulating the heat exchange powerof the radiator under the corresponding working condition points according to the optimized mathematical model. The accuracy of the simulation result of the heat exchange performance of the radiatorcan be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of cooling systems, in particular to a method and system for simulating heat exchange performance of radiators. Background technique [0002] The radiator is the core component of the automobile cooling system, which can ensure a fixed heat transfer performance under a certain temperature difference between the coolant and the air and a certain flow rate of the coolant and the air. The heat transfer performance of the radiator is a key parameter in the design matching of the automobile cooling system. [0003] At present, for the heat transfer performance simulation of vehicle radiators, the wind tunnel experiment of a single radiator is usually carried out. The theoretical basis of the wind tunnel experiment is the principle of relativity of motion and the principle of flow similarity. Through the wind tunnel experiment of the radiator single product, the effect diagram of different heat transfer is obtain...
