Gas pressure wave generator for regenerative type refrigerator

Abstract

本发明涉及一种回热式制冷机用气体压力波发生器,包括电机、波纹管组件和固定外壳。电机和波纹管组件位于固定外壳内。电机包括定子部件、动子部件和软磁体。波纹管组件包括波纹管和分别与波纹管两端固定相连的基体及盲板。基体位于波纹管内,且基体上设有排气口。基体、盲板和波纹管内壁围成压缩腔,并且密封。波纹管固定于基体的一端与定子部件固定相连,波纹管固定于盲板的一端与动子部件固定相连。波纹管与动子部件的固定端,在动子部件的带动下沿波纹管轴向做往复运动,在充有气体时,使气体产生压力波动。由以上技术方案可知,本发明无需压缩活塞与压缩气缸,消除了现有压缩机制造难度大、压缩效率低、气体需要量大的缺陷。
The invention relates to a gas pressure wave generator for a regenerative type refrigerator. The gas pressure wave generator comprises motors, a corrugated pipe component and a fixed housing. The motors and the corrugated pipe component are arranged in the fixed housing. The motors comprise stator components, mover components and soft magnets. The corrugated pipe component comprises a corrugated pipe, a base and a blind plate. The base and the blind plate are fixedly connected with two ends of the corrugated pipe respectively. The base is arranged in the corrugated pipe and provided with an air exhausting outlet. The base, the blind plate and the inner wall of the corrugated pipe are combined to form a sealed compressing chamber. One end, fixed to the base, of the corrugated pipe is fixedly connected with the stator components, and one end, fixed to the blind plate, of the corrugated pipe is fixedly connected with the mover components. The end, fixed with the mover components, of the corrugated pipe is driven by the mover components to do reciprocating motion along the axial direction of the corrugated pipe, allowing pressure surge to occur to the filled gas. According to the technical scheme, the gas pressure wave generator is free of a compressing piston and a compressing cylinder and overcomes the defects of difficult production, low compressing efficiency and requirement on high quantity of the gas of the conventional compressor.
