Summary: | The invention discloses a multi-layer co-extrusion cooling pipe and a preparation method. The invention relates to the technical field of cooling pipes, in particular to a cooling water path pipe in anew energy automobile battery pack. The invention provides the multi-layer co-extrusion cooling pipe which is resistant to permeation and environment stress cracking and is suitable for new energy vehicle battery pack heat dissipation application occasions, and the preparation method. A multi-layer structure of the pipe is manufactured through co-extrusion of multiple layers of molds and then curing molding; the pipe comprises at least one protective layer and at least one modified high-density polyethylene (HDPE) layer; the protective layer and the modified HDPE layer are arranged at intervals; bonding layers are arranged between the layers arranged at intervals; and the modified HDPE layer is made of silane crosslinked high-density polyethylene. According to the multi-layer co-extrusioncooling pipe and the prep |
