To shorten the time needed to analyze a temperature of a coolant.SOLUTION: A coolant temperature analysis method comprises: a pre-analysis process of calculating a flow of a gas at a periphery of a heat exchanger 3 exchanging heat between a coolant and the gas; a specifying process of specifying, based upon an analysis result of the pre-analysis process, a rate α of a gas flowing around to pass through the heat exchanger 3 again after passing through the heat exchanger 3; and a main analysis process of using the ratio α specified in the specifying process to predict a temperature Tc of the gas before passage of the heat exchanger 3, and also using the predicted temperature Tc of the gas to calculate a temperature of the coolant through linear CAE analysis.SELECTED DRAWING: Figure 1

    【課題】冷媒の温度の解析にかかる時間を短縮する。【解決手段】冷媒と気体との間で熱交換させる熱交換器3の周辺における気体の流れを三次元のCAE解析で算出する事前解析工程と、事前解析工程の解析結果に基づき、熱交換器3の通過後に再び熱交換器3を通過するように回り込む気体の割合αを特定する特定工程と、特定工程で特定された割合αを用いて熱交換器3の通過前における気体の温度Tcを予測し、予測した気体の温度Tcを用いて一次元のCAE解析で冷媒の温度を算出する主解析工程とを備える。【選択図】図1
