HARMONICA TUBE AND PREPARATION METHOD THEREOF, LIQUID COOLING PLATE, BATTERY, AND ELECTRIC APPARATUS

原文（中国語）

This application discloses a harmonica tube and a preparation method thereof, a liquid cooling plate, a battery, and an electric apparatus, where a material of the harmonica tube includes a polyphenylene sulfide composition, and the polyphenylene sulfide composition includes a polyphenylene sulfide resin and a toughening agent; the toughening agent includes a copolymer of an olefin and a glycidyl ester. By providing the polyphenylene sulfide composition as the material for the harmonica tube, this application facilitates reducing issues such as material breakage or poor extrusion flow during extrusion molding, enabling the formed harmonica tube to exhibit excellent mechanical strength, deformation resistance, corrosion resistance, heat resistance, heat dissipation, and creep resistance, lowering the risk of cracking under pressure during use, and enhancing production capacity and product quality.
