Description

高压储氢瓶 技术领域
本发明属于储氢技术领域，更具体地，涉及一种高压储氢瓶。
背景技术
在高压下(15.2～70.9兆帕)氢气可以装盛在气体瓶中运输，并通过减压阀的调节直接释放氢气，其方便可靠，是最普通和最直接的储氢方式。随着材料科学的发展，已开发出碳纤维与铝复合材料的高压气瓶，大大降低气瓶自身质量，提高容量装载效率，使高压储氢成为较有竞争优势的车载储氢方式。在现有技术中，高压储氢瓶需要单件生产且缠绕层数较多，时间耗费长，同时为了保证整体爆破能力，在直筒段设置缠绕冗余，内胆重量及纤维用量较大，整体重量较大。
因此，期待研发一种高压储氢瓶，降低内胆重量及纤维用量，并提高高压储氢瓶的爆破压力及容重比。
发明内容
本发明的目的是提供一种高压储氢瓶，降低内胆的质量及缠绕层厚度，并提高承载能力。
为了实现上述目的，本发明提供一种高压储氢瓶，包括：内胆和缠绕层，所述内胆的外侧面上设有凹槽，所述凹槽中填充有编织层；所述缠绕层缠绕于所述内胆的外壁上，且将所述编织层包裹在内。
