摘要

基于一台100 W级?型斯特林发动机

提出了一种适用于太阳辐射与燃烧加热2种加热方式的加热器结构

其工质流道和集热腔为一体。数值模拟结果表明

在完全利用燃烧加热、完全利用光辐射加热以及光辐射和燃烧供热量为1:1等3种情况下

加热器可以满足热端工质吸收热量大于1 600 W的要求

并且壁面温度分布在合理范围内。本热源互补加热器可以实现系统连续运行

减少燃料消耗。

Abstract

On the basis of a ?-type small scale Stirling engine

a design of Stirling engine heater which is suitable for two external heat sources

solar energy and combustion

is proposed. The structure intergrates working gas channels into walls of the heater. The numerical simulation results show that

under all the three conditions

only combustion as heating source

only solar energy as heating source and equal heating load of the two heating sources

the above heater can meet the requirement of providing enough heat(1 600 W) for working gases

and the temperature distribution on the heater's walls is reasonable.
