Abstract

A method for processing thermal performance data of radiator bench is provided. As the radiator core is divided into uniform hexahedron meshes, and the heat balance equation is established for each individual grid, at the same time, a local element heat exchange coefficient is obtained, the mass flow on the cold side of the radiator bench thermal performance data is thus combined with the mass flow on the cold side, mass flow and heat dissipation on the hot side are converted to cold side velocities, heat side velocity and local element heat exchange coefficient, and then fitting the discretedata in the heat exchange coefficient table of the local element, a continuous function expression related to the magnitude of the flow velocity through the mesh element is generated, finally, the fitting degree of the method is generally above 0.98, which is very consistent with the actual heat dissipation performance characteristics of the radiator. Therefore, the data processing of the heat dissipation performance of the radiator bench is more accurate and has the advantage of wide application range.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for processing heat performance data of a radiator stand. Background technique [0002] In automobiles, the radiator is a component that dissipates heat from the engine, and the bench test data is used to characterize the heat dissipation performance attribute parameters of the radiator. Using these attribute parameters as the input data of the radiator core components in the vehicle thermal management simulation analysis, the water temperature at the outlet of the engine water jacket can be calculated, and the water temperature can be used to judge whether the engine is in a normal working state. Therefore, scientifically and rationally processing the heat dissipation performance data of the radiator bench plays a key role in the accuracy of the simulation calculation results. [0003] For the automobile design stage, in the prior art, the outlet water temperature ...
