摘要：A new type of heat pipe assisted thermoelectric generator (HP-TEG) for automobile exhaust waste heat recovery is proposed in this paper. To confirm the optimized configurations of the thermoelectric device, an experimental prototype was constructed to obtain the best heat pipes insertion depth (D-hp), and the optimum angle between the heat pipe row and the gas flow direction (theta(hp)). A HP-TEG device was designed, constructed after the optimization of heat pipes depth and angle. The operating parameters were further investigated to enhance the performance of thermoelectric generation (TEG). The experimental results show that the power output of HP-TEG preferred high exhaust temperature, cold water flow rate and mass flow rate. The maximum open circuit voltage of 36 thermoelectric modules (TEMs) is measured as 81.09 V. The corresponding power output and pressure drop are 13.08W and 1657 Pa, respectively, with an optimized thermoelectric power generation efficiency of the HP-TEG as 2.58%. (C) 2017 Elsevier Ltd.
