Hollow discharger for stirling cryocooler and vacuum air extraction device thereof

Abstract

The invention discloses a hollow discharger for a stirling cryocooler and a vacuum air extraction device thereof. The stirling cryocooler comprises an improved discharger end cover, a discharger casing, a valve element, an air extraction valve seat and an air extraction valve rod. The hollow discharger is applied to a regenerator and the stirling cryocooler of the discharger, the vacuumizing is conducted on the discharger, the vacuum degree is kept, and the heat conductivity of the discharger is effectively reduced. The valve element is in threaded connection with the discharger end cover, a sealing groove is formed in the bottom of the valve, and a sealing ring is installed. The air extraction valve seat is in threaded connection with the discharger end cover, sealing rings are installed on the upper end face of the air extraction valve and the discharger end cover, and a hole is formed in the side of the extraction valve and connected with a vacuum pump. One end of the air extraction valve is embedded in a straight slot in the top end of the valve element and used for screw the valve element out. A sealing ring is arranged between the air extraction valve rod and the air extraction valve seat for sealing. In the vacuumizing process, air in the discharger is extracted from a through hole of the valve element. After the vacuumizing process, the valve element is screwed tightly, the sealing ring is pressed tightly, and vacuum sealing in the discharger can be achieved.

AI Technical Summary

Benefits of technology

This patented design for an air-purged type refrigzer has several technical benefits that make it easier to work with while maintaining good performance over time.

Problems solved by technology

This patented technical solution described by Heat Conductive Technologies (HCT) describes how an expandable material can be used for separators between a condenser and a compressor that create thermal contact with each other when they move back and forth at different speeds or directions. However, due to these differences caused by changes in temperatures, some parts may lose their ability to effectively absorb excess energy while others still work properly. To solve this issue, it suggests keeping them under pressure until needed again after use.
