摘要

本研究經由熱電模組發電性能測試，次系統流場均勻化模擬，單面熱電發電次系統測試與次系統耐壓測試等資料進行堆疊式熱電發電次系統設計，最後進行kW級堆疊式熱電發電系統製作與測試。其結果顯示以6組冷熱端組成之堆疊式熱電發電次系統，當高溫端鰭片表面溫度為142℃，低溫端鰭片表面溫度為45℃，其最大發電量為557 W，換算為功率密度約為19 kW/m^3。kW級堆疊式熱電發電系統由8組500 W級堆疊式熱電發電次系統所組成，當熱源溫度164.5℃與冷源溫度40.1℃下，其最大發電量為4.42 kW。

In this study, the stacked thermoelectric power generation subsystem was designed by thermoelectric power generation module performance tests, subsystem flow field simulations, single layer thermoelectric power generation subsystem tests and subsystem pressure tests. Then, the 4 kW stacked thermoelectric power generation system was fabricated and tested. The results show that the stacked thermoelectric power generation subsystem consists of six layers of thermoelectric modules. When the surface temperature of hot side is 142 °C and the surface temperature of cold side is 45 °C. The maximum power output of the stacked thermoelectric power generation subsystem is 557 W, and converted to a power density is about 19 kW/m^3. The 4 kW stacked thermoelectric power generation system consists of 8 sets of stacked subsystems. When the hot side temperature is 164.5 °C and the cold side temperature is 40.1 °C, the maximum power output of thermoelectric power generation system is 4.42 kW.
