摘要

为解决无电区域和火灾、地震和雪灾等特殊条件下的供电问题，设计了一种可燃用木柴和木炭等生物质燃料的水冷式温差发电机，其特点在于引入了一种辐射型的集热器。温差发电机的总质量为23.3 kg，集成了直流稳压器，可稳定地对外输出电能。测试了温差发电机的启动特性、空载特性和功率负载特性，结果表明：该温差发电机的平均工作温差为68℃，最大空载电压达到116.3 V。当接入负载时，输出功率随外部负载电阻的增大而降低。当外部负载为1.6 Ω时，温差发电机可对外输出最大功率为22.4 W；继续降低负载电阻时，温差发电机将不能维持稳定地输出电能。

Abstract

In order to supply electricity in off-grid areas and under emergency conditions such as fire accident

earthquake

and snow disaster

a water-cooled thermoel-ectric generator was designed

which can be fueled with wood

charcoal and other biomass

and it is featured by the incorporation of a radial-shaped heat collector. The ther-moelectric generator

weighting of 23.3 kg

incorporates a DC-DC converter to stabilize the output voltage. The start-up performance

no-load characteristic and power load feature of the thermoelectric generator were studied in detail. Results show that the average temperature difference is approximate 68℃

and the maximum no-load voltage reached 116.3 V. In loaded case

the electric power output decreases with the external load resistance. The maximum electric power output is found to be 22.4 W when the external load resistance is 1.6 Ω; and the thermoelectric generator is not able to output electricity steadily when the external load is reduced hereby.
