An improved tube assembly device

Abstract

This utility model relates to the field of refrigeration machinery technology, specifically to an improved pipe assembly device. In existing refrigeration machinery, the cooling medium is distributed from a main pipe to various branch pipes. The main pipe has a circular cross-section, and the branch pipes and the main pipe are directly welded together, resulting in relatively poor strength, high processing difficulty and requirements, and a tendency for leakage at the weld joints. The improved pipe assembly device features a flat, open-end main pipe sealed with caps at both ends. A transition seat is provided on the main pipe and caps, with its arc-shaped surface fitting over the inner hole of the main pipe or cap, and its stepped surface conforming to the plane of the main pipe or cap. First, second, third, and fourth branch pipes are inserted into the transition seat. This utility model has a reasonable structure; the flat main pipe increases the storage capacity of the cooling medium, the increased cross-sectional area allows for a longer medium residence time, and improved heat exchange capacity; the use of transition seats for pipe connection increases strength.
