하이브리드 자동차의 히트파이프 배기열 회수장치 개발

A new progressive advanced approach (Loop thermosyphon Thermoelectric Power generation System) is suggested to optimize heat recovery from vehicle exhaust gas. The present thermoelectric generators (TE) system offers the potential to increase vehicle fuel economy by converting a portion of engine waste heat to electricity. The feasibility of TE system is assessed in the context of hybrid electric vehicles. The present new TE system adopted heat pipes as a cooling heat exchanger of TE module. The present simulation study has been performed with CFD thermal modeling tool. In the present study, the proposed TE generation system for the future hybrid car could be recognized as the new waste heat recovery system. It was observed that the power output of the present TE generation system affected by various variables such as cooling media, thermal contact and supplied power etc. The present simulation results with the heat pipe TE module shows possibilities as an improved TE system for future thermoelectric hybrid vehicles.
