Thermoelectric Energy Conversion System Design And Optimization Based On Seebeck Effect

Wireless sensor networking technology widely used in the IOT direction has a significant role in promoting the development process of IOT cutting-edge. However, due to the extensive application of wireless sensors, the energy source supply problems have become increasingly prominent. To provide technical solutions to the DC power supply for wireless sensors, this study suggested applying the nature of the environment through the use of energy thermoelectric energy conversion, which is capable of converting the solar radiation energy into electricity through the thermoelectric energy conversion system. Concrete results of this study are as follows:1. Based on solar radiation and air temperature difference, a thermoelectric energy conversion system is designed and developed. Salient features of the system include the creative design of a cooling module under anhydrous conditions and inventive composition of an all glass heat tube type vacuum solar heat collecting pipe.2. Adoption of thermoelectric energy conversion processes in-depth study and optimization, gravity assisted heat pipe is selected as a core component, which contributes to the design of a new gravity assisted heat pipe thermoelectric energy conversion system. As gravity assisted heat pipe is added, the output capacity of the entire gravity assisted heat pipe thermoelectric energy conversion system has been substantially improved.3. Under real outdoor condition, experiments are repeatedly carried out. The results show that the thermoelectric energy conversion system can achieve the output of 286 mV to 4.4V and 4.7mW; while the gravity assisted heat pipe thermoelectric energy conversion system can achieve the output of 1057 mV to 4.4V and 362.56 mW. The above parameters prove that energy supply problem of the wireless sensor system working at 4.7-362.56 mW has been provided with an effective solution.
