“…To improve the performance of TEC, many works [12][13][14] attempted to maximize the coefficient of performance (COP) or cooling capacity (Qc) of TEC by applying external current/voltage sources and determining the best working conditions. Another approach is to use a thermoelectric generator (TEG) [15][16][17][18][19][20][21] as an energy harvesting engine for TEC, leading to self-powered TEC-TEG combined cooling systems [22][23][24][25][26][27][28]. For example, in [22], the possibility of using solar TEG to power TEC was investigated.…”

Thermoelectric coolers (TECs) are widely used in state-of-the-art thermal management systems. Recently, there is a big trend that is to power TECs using thermoelectric generators (TEGs). Mainstream research efforts focus on attaining a higher figure of merit (ZT) of thermoelectric material, which now faces a great challenge. Alternatively, this paper proposes a different approach to improve the performance of TEC, i.e., integration of a thermoelectric generator (TEG) with a TEC. The TEG converts the collected heat energy into electric current, which reduces the power consumption and enhances the cooling capacity of the TEC. Using different methods of connecting the TEC and TEG, two thermoelectric collaborative cooling systems are proposed. Accurate SPICE models of the two cooling systems are established. Experimental results demonstrate that the discrepancy between the currents flowing through the TEC in the experiments and in the SPICE models is less than 4.8% on average. Based on the verified SPICE models, the proposed TEC-TEG collaborative cooling systems are assessed in terms of power consumption, cooling capacity, coefficient of performance, and cooling efficiency. Compared with a typical Peltier cooling system, the two collaborative cooling systems achieve significant performance improvements.

Energy‐harvesting technologies offer a sustainable, maintenance‐free alternative to conventional energy‐storage solutions in distributed low‐power applications. Flexible thermoelectric generators (TEGs) can generate electric power from a temperature gradient, even on complex surfaces. Organic materials are ideal candidates for flexible TEGs due to their good solution‐processability, natural abundance, low weight, and flexibility. Electronic and thermoelectric properties of organic materials have steadily progressed, while device architectures leveraging their advantages are largely missing. Here, a design and fabrication method are proposed for producing fully screen‐printed, flexible monolithic organic TEGs scalable up to m2, compatible with any screen‐printable ink. This approach is validated, along with its scalability, by printing TEGs composed of two different active inks, in three configurations, with up to 800 thermoelements, with performances well matching simulations based on materials parameters. It is demonstrated that by using an additive‐free graphene ink, a remarkable power density of 15 nW cm−2 at ΔT = 29.5 K can be achieved, with an estimated weight‐normalized power output of 1 µW g−1, highlighting a strong potential in portability. Owing to such power density, only limited areas are required to generate microwatts, sufficient for operating low‐power electronic devices such as sensors, and wearables.

Submarine hydrothermal fluids contain substantial energy, and temperature differences with the surrounding cold seawater can provide energy for seabed observations and submarine operations. This study proposes a novel hydrothermal power generation device comprising a thermoelectric converter and an energy management system. Herein, a waterproof module with high-temperature and high-pressure resistance was designed. Heating and pressurization tests were performed to verify the structure's feasibility. The overall structure of the system based on the module was then designed, and laboratory performance tests were conducted. A computational fluid dynamics simulation was used to further analyze the heat transfer model. The simulation results are consistent with experimental data, validating the simulation model's accuracy. The new device reduces its own weight and solves low heat transfer efficiency problems. This study increases the temperature difference between the two ends of the thermoelectric generator in the thermoelectric converter by 76.2%.INDEX TERMS CFD simulation, energy conversion, heat transfer model, hydrothermal fluid, submarine energy.
