The three dimensional simulating study of the flow and heat transfer in detached vehucular cooling-compartment

Abstract

Papers presented to the 11th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 20-23 July 2015.To explore the internal flow distributions and heat transfer mechanism in detached cooling-compartment, two three- dimensional models both including the heat exchangers and a full-sized fan model were established and analyzed in this paper. According to the study, the opposite model, on which the heat exchangers were located separately and close to the inlets, was considered to be more efficient. Besides, the opposite arrangement in detached cooling-department offered the possibility to control the mass flow on each heat exchanger independently, which could further increase the cooling efficiency. It deserves more attentions in the future.
