Thermal Presentation of Two-Phase Congested Thermosyphon in Submission of Determined Thermoelectric Dominance Producer by Means of Phase Change Material Thermal Storage

Abstract:

With the growing energy command due to growing world people and industrialization, utilizing strenuous solar energy for thermal and electrical power production will be the future renewable power source to decrease the confidence on fossil fuel and reduce carbon dioxide discharge. Besides by means of determined Photovoltaic (CPV) system, Concentrated Thermoelectric generator (CTEG) will be another possible option for sustainable power generation. The CTEG system utilizes concentrated solar flux as a heat source to the thermoelectric generating (TEG) module in generating direct current thermoelectricity which can be easily converted to alternating power using an inverter. By maintaining a temperature difference between the hot and cold sides of the thermoelectric cells (Seebeck effect), thermoelectricity is generated where its magnitude is a function of temperature difference. The main challenge is the effectiveness of excess heat removal which accumulated at the cold side of the thermoelectric cell to achieve greater power generation. Using acting cooling mechanisms are not energy efficient proposal as it requires power in operating them and significantly reduces the total power output generated. They are planned in the paper for working CTEG system through passive cooling and achieving invariable cooling. Two-phase closed thermosyphon is implement as an helpful heat transporting device for transfer excess heat from heated TEG part to the frozen PCM storeroom reservoir for heat luggage compartment. This investigation is to evaluate the thermal presentation of the proposed system.. The working fluid used in the thermosyphon was Acetone and its filling ratio was designated at 40% of the evaporator volume. Paraffin wax was selected as PCM with melting point of 47oC and acceptably high latent heat storage was selected in the thermal storage. The passive cooling mechanisms consist of PCM storage tank, heat pipe-based heat transfer system for transporting heat from TEG modules to the PCM thermal storage during the daytime and a similar heat pipe-based system for discharging heat from PCM storage tank to the cooler ambient during the night time.
