探讨一种内嵌型斯特林制冷机,特点之一是膨胀机与压缩机分布在同一轴线上,并将膨胀机内嵌于压缩机内部,实现结构简短的目标;特点之二是压缩机中压缩气缸与电机中动子固连,在直线电机驱动下往复运动,与固定的压缩活塞形成压缩腔;特点之三是分置管内置于压缩活塞内部。同时根据热力学参数及结构参数,对制约整机性能的关键部件直线电机及回热器进行优化设计,从理论上验证此种结构的可行性。
To discuss an embedded Stirling refrigerator, one of the features is that the expander and the compressor are distributed on the same axis, and the expander is embedded inside the compressor to achieve the short-term goal of the structure. The second characteristic is that the compressor In the compression cylinder and the motor mover fixedly connected, reciprocating motion driven by a linear motor, and a fixed compression piston to form a compression chamber; the characteristics of the third is built-in compression piston inside the piston. At the same time, according to the thermodynamic parameters and structural parameters, the optimal design of the linear motor and the regenerator, which are the key components of the whole machine, is verified. The feasibility of this kind of structure is verified theoretically.
