Study of the influence of heat exchangers' thermal resistances on a thermoelectric generation system

Start-up modes of thermoelectric generator based on vehicle exhaust waste heat recovery

“…Astrain et al [18] studied the influence of the thermal resistance in the heat exchanger on a TEG system. Chen et al [19] proposed a three-dimensional model of TEG in fluid power systems.…”

A novel thermoelectric generation system with thermal switch

“…According to Chen et al [9,10], the number of TE elements and heat transfer surface area of TEG play the most important roles in its power output and efficiency. Astrain et al [11] carried out a computational study about the influence of the thermal resistances of the heat exchangers on the efficiency of a TEG device. Meanwhile, a complete numerical model of TEG with finned heat exchangers has been established to investigate the influence of various irreversibilities by Meng et al [12].…”

Thermoelectric Power Generation Optimization by Thermal Design Means

“…Resolution methodology is based on previously published and validated computational model [26,49]. Particularly, this model considers temperature loss of flue gases, while they circulate along TEG, occupancy ratio and mass flow of refrigerants.…”

“…Optimization of heat exchangers attached to hot and cold sides of TEMs is very important to maximize thermoelectric power generation, and improvement in thermal resistances will result in higher temperature difference between hot and cold TEM sides close to temperature difference between heat exchangers, and, hence, will provide higher thermoelectric power generation [26][27][28][29]. Optimization of heat dissipation systems can be done by modifying their geometry, such as increasing number, height or spacing of fins of finned dissipator [30,31] or by properly selecting channel's diameter, internal distribution and/or internal inserts of cold plates [32][33][34][35].…”
