Abstract

本实用新型涉及一种圆柱型蓄电池外壳，包括有一圆筒形外壳，其圆筒形外壳外表面上设有至少二条纵向沟槽。该实用新型加工简单、不增加生产成本，扩大了散热面积，提高了耐压强度，适合于一些特殊环境中使用。

Description

圆柱型蓄电池外壳
技术领域
本实用新型涉及一种用于制作圆柱型蓄电池的外壳。
背景技术
目前使用的圆柱型蓄电池，其外壳为直筒形，在某些高温、受压特殊环境条件下使用时，电解质易流淌，外壳会变形，缩短了其使用寿命，其原因是外壳散热性差，不耐压等所造成。
实用新型内容
本实用新型的目的在于提供一种耐压、易散热的圆柱型蓄电池外壳。
本实用新型的目的是这样实现的：一种圆柱型蓄电池外壳，包括有一圆筒形外壳，所述圆筒形外壳外表面上设有至少二条纵向沟槽。
上述中，所述纵向沟槽数量为二至四十条。
该实用新型加工简单、不增加生产成本，扩大了散热面积，提高了耐压强度，由它制作的蓄电池适合于一些特殊环境中使用。
附图说明
图1为本实用新型一个实施例主视图；
图2为图1的A-A剖视图。
图3为本实用新型另一个实施例主视图。
具体实施方式
下面结合附图及实施例详述本实用新型。
如图1-2所示，一种圆柱型蓄电池外壳，包括有一圆筒形镀镍外壳(1)，其在圆筒形外壳(1)外表面上设有六条纵向沟槽(2)，其作用是增加了散热表面积，避免因蓄电池内温度升高而影响电解质的稳定性。另外，也提高了圆筒形外壳(1)的抗压强度，防止蓄电池内压或外界碰撞而引起外壳变形，影响蓄电池的正常使用。图3所示，其圆筒形外壳(1)外表面上设有三十四条纵向沟槽(2)。圆柱型蓄电池外壳上的纵向沟槽(2)，其数量

Claims (2)

1、一种圆柱型蓄电池外壳，包括有一圆筒形外壳(1)，其特征在于：所述圆筒形外壳(1)外表面上设有至少二条纵向沟槽(2)。
2、根据权利要求1所述的圆柱型蓄电池外壳，其特征在于：所述纵向沟槽(2)数量为二至四十条。
