Production manner of the accumulator for the refigerating plant and has that the refigerating plant

摘要

PURPOSE: To suppress the amount of occurrence or the amount of leaving of foreign matter such as processing oil, scale oxides, moisture, chlorine compounds, etc., which may cause the drop of refrigerating capacity by manufacturing an accumulator, drawing both its ends while letting inert gas flow. ;CONSTITUTION: An accumulator 10 is manufactured by drawing both ends of a copper pipe by shifting jigs 9a and 9b while rotating them each in the direction of an arrow R without using processing oil such as rape oil, etc., while letting inert gas flow. Next, after cleaning of a variety of pipes, they are dried and blown by inert gas. A variety of pipes being treated in pretreatment process are combined this accumulator body 10, and they are brazed without using flux while letting inert gas flow to go through it well into the accumulator body 10 and a variety of pipes. After this brazing, it is cooled to the vicinity of ordinary temperature while blowing inert gas so as to get an initial accumulator for a refrigerator.;COPYRIGHT: (C)1996,JPO
