“…Most previous work on TEC system has examined optimization and performance improvement of electronic devices by building various thermoelectric modules, Shen et al (2013), Cai et al (2016), Cai et al (2017), Chen et al (2015), Lineykin and Ben-Yaakov (2007), Manikandan and Kaushik (2015). However, increasing the performance of the cooler box is difficult due to low COP (coefficient of performance) of the thermoelectric module (TE).…”

A comparison study of the use of two different heat removal units was conducted to examine the performance of thermoelectric cooler box. The heat removal units employed were a heat sink fin-fan and a double fan heat pipe. Parameters measured as performance indicators are cooling capacity, temperature differences, and COP. In addition, the effect of electrical power on temperature difference and COP was also investigated. The cooler box size is 285 mm x 245 mm x 200 mm and constructed from styrofoam. The results show that there is no difference of the use of a double fan heat pipe or a heat sink fin-fan on the cooler box performances. The Carnot COP decreases with the time, while the experimental COP increases with the time then it is constant after the steady condition has been achieved. Increasing the power decreases the COP but increases the temperature difference.

“…Houcheng Zhang et al used cascaded TEG and TE cooler for waste heat recovery from fuel cells. However, most of the existing researches focus on numerical model research or just achieve more output from a single heat source through cascaded method . In this work, CTEG was applied in practice and can achieve hundreds watts level output.…”

Summary Thermoelectric generation (TEG) has its unique advantages in terms of distributed energy supply, low‐grade heat recovery, and clean energy technology, but its low efficiency has constrained its application and promotion seriously. In order to obtain satisfactory efficiency and realize the adaptability to different heat sources, a novel cascaded TEG system (CTEG) is proposed. According to the temperature of heat source, three types of thermoelectric modules are used in the generator system. The module arrangement, cooling medium, and mode directly affect the performance of this whole system, since that the detailed model and CFD simulation were conducted to obtain the optimal collocation. Based on the optimization modeling, a CTEG prototype was constructed. From the experimental results, the efficiency of the CTEG achieved 5.92%, which significantly improved about 21.56% compared with the TEG which only contains one stage. Moreover, the key parameters of the system were identified. The stability and the improvement of the system were discussed comprehensively. For TEG system, CTEG increase the utilization of high‐temperature heat sources, but also provides a structure for a TEG adapting to multiple temperature heat sources.

“…Their studies reveal that there was an optimum configuration of the system, beyond that any addition of leg pairs resulted in the degradation in the performance of the system. Chen et al [11] examined the two-stage cascaded module thermoelectric generator. They showed that the device performance could be achieved for a specific leg length allocation ratio.…”

Summary Thermal analysis of a segmented thermoelectric generator is performed, and the segmented leg configurations maximizing the efficiency and the output power are formulated. The effect of operating conditions such as external load resistance, the temperatures of hot and cold junctions, on the device performance is studied. The segmented thermoelectric generator has the leg configuration consisting of the combination of modified lead telluride and modified bismuth telluride. The segmented thermoelectric generator performance, such as device efficiency and output power, is compared with those corresponding to a single material leg configuration (modified lead telluride or modified bismuth telluride) for various operating conditions. It is found that a unique value of the segmented leg combination maximizes the efficiency and the output power for each operating condition. The variation in the operating conditions changed the locus points of the maximum efficiency and the maximum output power. The segmented thermoelectric generator gives rise to the higher device efficiency and the output power than those of the single material leg configuration, especially for the low external load resistance.
