The invention relates to the field of heat dissipation in automobile cabins, in particular to a method for analyzing heat dissipation in an automobile cabin. The method includes the following steps: firstly, air characteristic parameters and heat exchange characteristic performance parameters of cooling cores need to be tested, and input parameters are fitted in a numerical processing mode, so that influences of the air end and the heat end of a cooling system on a flow field structure and influences of the air end and the heat end of the cooling system on the heat exchange efficiency can be shown in an analysis model; secondly, in working condition inputting, the inlet temperature boundary of cooling liquid is obtained through a standard whole-automobile performance test; finally, the result is analyzed, and related parameters are adjusted through a comparative standard of testing data to guarantee that the state of the analysis model can replace that of a true automobile. According to the method, the flow field and the temperature field in the cabin and the performance of the cooling system can be rapidly, accurately and reliably analyzed in the automobile product design stage, and risks of later-period true automobile verification can be reduced.
