Title:
PIPE ASSEMBLY, COMPRESSOR, REFRIGERATION DEVICE, AND METHOD FOR MANUFACTURING PIPE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2023/106223
Kind Code:
A1
Abstract:
A pipe assembly (60) comprises an inner pipe (70), an outer pipe (80), and a brazing material (61). The inner pipe (70) has an outer-peripheral-surface first portion (71) and an outer-peripheral-surface second portion (72). The inner pipe (70) constitutes a refrigerant passage of a compressor (11). The outer pipe (80) has an inner-peripheral-surface first portion (81) and an inner-peripheral-surface second portion (82). The outer pipe (80) constitutes an injection path (54). Due to the inner pipe (70) being partially inserted into the outer pipe (80), the outer-peripheral-surface first portion (71) is in contact with the inner-peripheral-surface first portion (81). The brazing material (61) is placed in a brazed gap (65) between the outer-peripheral-surface second portion (72) and the inner-peripheral-surface second portion (82). The brazing material (61) secures the outer-peripheral-surface second portion (72) and the inner-peripheral-surface second portion (82).
