摘要

热电发电机是一种固态装置,当热电材料之间存在温差时,利用塞贝克效应将热量转化为电能。本研究利用16个SP1848-27145模块并联设计了热电热风发生器。该系统由生物质燃烧室、热风排风器、冷热侧换热器组成。测量了燃烧室、热风排热器、热侧换热器和冷侧散热器内的电压、电流和温度。实验过程中,热排风器、热侧散热器和冷侧最高温度分别为178.3℃、69.2℃和44.5℃,开路电压为64 V,电流为1.99 A。利用ANSYS Fluent软件对所设计的热风排风器、热侧换热器和冷侧换热器的热性能进行了仿真,并以图形化的形式表示了它们的温度分布。

PERFORMANCE EVALUATION OF HOT AIR THERMOELECTRIC GENERATOR USING BIOMASS ENERGY SOURCE
Thermoelectric generators are solid-state devices that convert heat into electricity using the Seebeck effect, when there is a temperature difference across a thermoelectric material. This research designed an experimentally tested a thermoelectric hot air generator using sixteen SP1848-27145 modules in two parallel strings. The system consists of a biomass combustion chamber, hot air exhauster, hot and cold side heat exchangers. Voltage, current and temperatures in the combustion chamber, hot air heat exhauster, hot side heat exchanger and cold side heat sink were measured. The hot air exhauster, hot side heat sink and cold side maximum temperatures are 178.3°C, 69.2°C and 44.5°C respectively yielding an open circuit voltage of 64 V and current of 1.99 A in the course of the experiment. The thermal performance of the designed hot air exhauster, hot side heat exchanger and cold side heat were simulated using ANSYS Fluent, for pictorial representation of their temperature contours.
