Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle parts processing, and in particular to an automatic assembly device for flat tubes. Background Art

[0002] New energy vehicles require battery cooling during operation, and water cooling is currently the mainstream cooling solution. New energy battery packs utilize large-area cooling technology that places organ pipes underneath the battery pack, expanding the heat exchange area severalfold. By varying the position and contact area of ​​the organ pipes, cooling efficiency is enhanced, thereby improving fast charging efficiency. Installing organ pipes between batteries optimizes battery temperature control time, allowing rapid cooling of the battery panels under extreme conditions without thermal runaway, ensuring safety while also serving as a buffer and thermal insulation device. Aluminum heat transfer material is a key raw material for organ pipes, and catalytic aluminum heat transfer material is also in demand in the new energy industry. Given the importance of battery panels, the proper assembly of the organ pipes and the terminal is crucial. A properly assembled organ pipe will not leak during water cooling, and vice versa.
