Description

technical field

[0001] The invention relates to the field of engine heat dissipation testing, and more specifically, to a method and module for detecting heat dissipation performance of a vehicle environment radiator. Background technique

[0002] The heat dissipation performance test of the radiator mainly refers to the ability of the large cycle of the engine to transfer heat to the surrounding air through the radiator, which is an important part of the energy flow test of the whole vehicle. The existing heat dissipation performance test method of radiator is to use the heat transfer mode of double-flow device and single-flow device to establish the micro-channel model of the corrugated fin on the air side of the radiator and carry out simulation.

[0003] However, the existing heat dissipation performance tests of radiators mainly focus on the heat dissipation performance of the radiator itself, without considering the heat dissipation performance of the radiator in the v...
