Gas wave refrigerator

Abstract

The embodiment of the invention discloses a gas wave refrigerator, comprising an engine body, a bearing, a turning wheel distributor, a sealing structure and a receiving pipe; the engine body is provided with an air inlet and an air outlet; the sealing structure is arranged between the air inlet and the air outlet on the engine body; the engine body is provided with a receiving pipe connector, the receiving pipe is inserted into the receiving pipe connector; the sealing structure comprises a moving ring which can rotate along with the turning wheel distributor and a stationary ring which can not rotate along with the turning wheel distributor but can slightly move axially corresponding to the turning wheel distributor and the moving ring, and the stationary ring is arranged beside the moving ring; the receiving pipe is externally encircled with a shell, the shell forms a refrigeration cavity. The gas wave refrigerator of the invention features improved sealing effect due to the sealing structure thereof, reduced difficulty of manufacturing and assembly, greatly reduced heat generated by frictions, arrangement of the refrigeration cavity outside the receiving pipe which fast reduces temperature inside the receiving pipe, thus obviously improving refrigerating efficiency of the gas wave refrigerator.

Description

technical field [0001] The invention relates to a refrigeration machine, in particular to a gas wave refrigerator. Background technique [0002] Existing low-temperature refrigeration technology mostly uses multi-stage compressed refrigerants to achieve low temperature. The first stage compresses a refrigerant, and the second stage compresses the second refrigerant on the basis of absorbing the cooling capacity obtained by the first stage compression, and achieves the purpose of cooling through the vaporization and heat absorption of the refrigerant, usually the second stage compression The temperature of the refrigerant liquidation point used is lower than the liquidation point temperature of the first-stage refrigerant. There are many disadvantages in using this refrigeration method: firstly, due to the multi-stage compression, the refrigeration efficiency is low; secondly, due to the use of refrigerant, it is not conducive to environmental protection; Security risks. ...

Problems solved by technology

There are many disadvantages in using this refrigeration method: firstly, due to the multi-stage compression, the refrigeration efficiency is low; secondly, due to the use of refrigerant, it is not conducive to environmental protection; Security risks

The use of this sealing structure requires very strict precision for the matching gap between the moving and static plates, and the processing and assembly are difficult. During operation, the friction and heat generation are serious, resulting in low cooling efficiency of the gas wave refrigerator, poor sealing effect, and a large space occupation.

[0006] 2. After the shock wave is generated in the receiving tube and the temperature is lowered, when the shock wave is absorbed in the absorption chamber, the temperature will rise again, so the heat will be transferred to the refrigerated air flow, resulting in the loss of cooling capacity
