Outer circulation dissipation type air wave refrigerating device

Abstract

The present invention discloses to an external circulation dissipating type air wave refrigerating machine, belonging to the air expansion refrigeration and deep cooling low temperature technical field. The refrigerating machine mainly consists of a jet flow nozzle, a revolving drum, a main axle, an external dissipating channel opening, an air inlet, an air outlet, an external dissipating inlet, an external dissipating outlet and an external dissipating device. The refrigerating machine is characterized in that the dynamic and static relations of the nozzle and a receiving pipe are completely reversed so that a rotational double-opening receiving pipe section is aligned, synchronously or with a certain circumferential angle staggered, to the stationary jet flow nozzle and the external dissipating channel opening. Heat dissipation no longer depends on the length of the receiving pipe, and pressure waves and retention gas are led out to the external of the machine so as to dissipate and use the energy. Ice clogs of the nozzle and the external dissipating channel opening can be removed by externally adjusting a gap between the nozzle and the revolving drum, or between the external dissipating channel opening and the revolving drum. Liquid is not easy to accumulate inside the receiving pipe. The liquid-carried running efficiency of the whole machine is not reduced. The machine is small in volume and in area occupation, and eliminates the hidden danger of pipe broken caused by vibration. The refrigerating machine can more sufficiently and rationally recover the energy in the using process, and improve comprehensive benefits of air wave refrigeration.

Description

technical field [0001] The external circulation dissipative gas wave refrigerator of the invention belongs to the technical field of gas expansion refrigeration and cryogenic low temperature. Background technique [0002] The gas wave refrigerator and its refrigeration technology emerged in the 1980s and have many applications in the field of gas expansion refrigeration. The "gas wave refrigerator", "multi-stage gas wave refrigerator" and "multi-tube jet oscillating refrigerator" developed and invented by Dalian University of Technology are the basic components of this technology and have all obtained national patents. [0003] However, the above-mentioned gas wave refrigerator is limited by its inherent structure, and some deficiencies are difficult to improve, such as: the whole machine is relatively large and occupies a large area. The receiving tube is long, the installation and fixing requirements are high, the vibration is relatively large, and it is easy to break due...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned gas wave refrigerator is limited by its inherent structure, and some deficiencies are difficult to improve, such as: the whole machine is relatively large and occupies a large area

The receiving pipe is long, the installation and fixing requirements are high, the vibration is relatively large, and it is easy to break due to the fatigue load of long-term operation, which brings certain safety hazards to the equipment

When dealing with petroleum gas and other occasions, the traditional gas wave refrigerator is easy to accumulate condensate in the receiving pipe, resulting in a reduction in the length of the pipe, the reduction of the heat dissipation area, and the decline in refrigeration efficiency.
