It is necessary to make the merge pipe (30) and the inlet pipe (3]) separately and weld them together. The merging pipe (30) is made by performing a closing process on both ends of a material pipe for the merging pipe to close the openings at both ends, and forming a gaseous refrigerant inlet in the peripheral wall. The inlet pipe (31) is made by performing a bulge process on the middle part of the raw material pipe for the inlet pipe, or by performing a swaging process on both ends. Therefore, there is a problem in that the number of parts for manufacturing the aggregator (AO) increases and the cost increases. Moreover, since each part is manufactured by processing the raw material, there is a problem in that the work, especially the processing for making the inlet pipe (31), is troublesome.

One gaseous refrigerant merging tubular bulge part communicates with each gaseous refrigerant introduction tubular bulge part and gaseous refrigerant merging tubular bulge part, and is connected to each gaseous refrigerant introduction tubular bulge part. Since the silencing tubular bulge part is formed in which the cross-sectional area of the passage is larger than the passage cross-sectional area of each gaseous refrigerant introduction tubular bulge part, two metal plates are used as parts. All you need to do is prepare. In addition, there is a method in which both metal plates are crimped so that a desired pattern of non-crimped parts is present, and then all the tubular bulges are formed at once, or a tubular bulge is formed on at least one of the two metal plates. It can be manufactured by a simple method such as forming a recess corresponding to the metal plate and then joining both metal plates.
