狭い角ダクト内にある直方体近傍の熱伝達率測定と熱回路モデル検討

抄録

A forced air convection is applied to some stationary battery systems for heat dissipation from battery modules installed densely in the board (1). Thermal Circuit Model(TCM) allows us to calculate battery cell temperatures in the battery module with a battery electrical equivalent circuit model (2). In this study, heat transfer coefficients of TCM are calculated experimentally with a battery module in a narrow squared wind tunnel. The heat transfer coefficients are implemented to a proposed TCM model. At result, a maximum error between experimental data and proposed model is 4.6 [K] which is corresponding to 5.4 % for a battery cell operating temperature range.
