摘　　要：利用通常的往复式磁制冷原理,采用伺服电机通过滚珠丝杠分别驱动磁场系统和热交换流体的方式,制作实现磁场系统移动速度和换热流体流速连续可调和可控的室温磁制冷机。触摸屏作为操控界面,操作简单方便,参数任意设定,数据自动采集,利用可编程控制器(PLC)及自编的控制程序控制伺服驱动器实现运动控制。这种结构设计方便系统研究往复式室温磁制冷机磁场系统运动速度及热交换流体流速对制冷效果的影响,可作为往复式室温磁制冷机参数的测试平台。According to working principle of reciprocal magnetic refrigerator, a highly controllable magnetic refrigerator has been constructed using advanced moving control technology, such as server motors, PLC, touch screen and self - programmed system control software. Its magnetic system moving rate and heat exchange fluid flowing rate are continuously controllable. It has many advantages such as low noise, high reliability, convenient and simple operation, auto - recorded data, and wide rang parameters setting etc. It can be used to systematically test the relation between the several parameters and the refrigeration performance for different magnetic refrigerants.
