The invention relates to the technical field of cables, in particular to a corrosion-resistant and high-temperature-resistant new energy automobile cable which comprises a cable core, a heat dissipation framework and a protective sleeve. The three strands of wire cores are all located in the protective sleeve, a first cavity is defined between every two adjacent wire cores and the inner wall of the protective sleeve, and a second cavity is defined among the three strands of wire cores; the plurality of heat dissipation frameworks are sequentially distributed in the length direction of the wire core, and every two adjacent heat dissipation frameworks deflect by 120 degrees in the circumferential direction of the wire core; the heat dissipation framework is composed of three sections of arc plates, and a heat dissipation groove is formed in the face, away from the corresponding wire core, of each arc plate. By arranging the heat dissipation framework, the three strands of wire cores can be separated, the second cavity and the first cavity can be communicated through the heat dissipation grooves, and heat among the three strands of wire cores can be dissipated; and the two adjacent heat dissipation frameworks deflect by a certain angle in the circumferential direction of the plurality of wire cores, so that the second cavities at different heat dissipation frameworks are communicated with one first cavity, and the heat dissipation effect is ensured.
本发明涉及电缆技术领域,具体涉及一种耐腐蚀耐高温的新能源汽车线缆,包括线芯、散热骨架、保护套;线芯有三股,均位于保护套内,每相邻两个线芯与保护套内壁之间限定出第一腔室,三股线芯之间限定出第二腔室;散热骨架有多个,沿线芯长度方向依次分布,且相邻两个散热骨架在线芯周向上偏转120°;散热骨架包括由三段弧板组成,每个弧板远离对应线芯的一面上均开设有散热槽;设置散热骨架不仅能将三股线芯隔开,还能通过散热槽使第二腔室与第一腔室连通,将三股线芯之间的热量散出;且相邻两个散热骨架在多个线芯的周向上偏转一定角度,使得不同散热骨架处的第二腔室与一个第一腔室连通,保证散热效果。
