【Abstract】This paper proposes to calculate the heat transfer performance of the heating core through CFD three-dimensional simulation. Through the comparison between simulation and test，the error is less than 2%，which meets the accuracy requirements and can be used for the simulation calculation of the heat transfer performance of the heating core. This also brings the research on the heat transfer performance of the heater core from the previous theoretical calculation and two-dimensional simulation into the three-dimensional simulation stage，which is of great significance to improve the simulation accuracy，reduce the cost and shorten the project development cycle.

【Key words】hear core；CFD；heat transfer performance
