Description

Technical Field

[0001] This invention relates to the field of engine heat dissipation technology, and more specifically to a multifunctional heat dissipation testing device and testing method. Background Technology

[0002] During the current engine and vehicle matching process, the first matched radiator and fan will be tested. Matching can only be performed based on the current altitude, current ambient temperature, and current configuration. When the above conditions change, the performance of the heat dissipation and intercooling system cannot be predicted.
