Title:
PIPE SLEEVE, PIPELINE DEVICE, AND AIR CONDITIONER HAVING PIPELINE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/061367
Kind Code:
A1
Abstract:
A pipe sleeve, a pipeline device, and an air conditioner having the pipeline device. The pipeline device comprises a first pipeline component, an annular groove having one end open and the other end closed being formed at an end of the first pipeline component; and a second pipeline component, the second pipeline component being welded and fixed to the first pipeline component, and a welding area being axially corresponding to the annular groove. In the pipeline device, the provision of the annular groove allows excess welding flux in the welding area to drop into the annular groove, such that welding flux is prevented from dripping onto parts inside the first pipeline component, thereby ensuring the cleanliness of the inside of the pipeline device, and preventing excess welding flux from entering a system pipeline to form welding bumps and causing damage to the system.
