Description

一种双制冷的电池箱 技术领域
本实用新型涉及电池箱领域，具体涉及一种双制冷的电池箱。
背景技术
有轨电车大多采用超级电池作为储能机构，超级电池是将数百块单体电池划分为若干个电池单元，经串、并联后形成高压、大电流的电池组，每个电池单元的数块单体电池放在一个箱体中，相邻的单体电池之间放置有隔板；使电池保持在24～30摄氏度的温度范围内工作，可以有效提高电池的充、放电效率，延长电池的使用寿命，因此必须采用合适的散热措施来应对电池工作时产生的大量热量。
目前有将电池装在导热材料制成的内箱体中，内箱体放入外箱体中，在内箱体中循环通入导热油，外箱体通过管道将由电池供电的制冷机构产生的冷空气吹入以带走热量的方案，由于电池充电时产生的热量要远多于放电时产生的热量，这就要求在电池充电时吹入更多的冷空气，现有技术是通过加大制冷机构中压缩机功率的方式来实现，压缩机同时也消耗更多的电量，这就延长了电池的充电时间。
发明内容
本实用新型要解决的技术问题是提供一种双制冷的电池箱，可以解决现有技术通过加大制冷机构中压缩机功率的方式来实现对电池充电时的快速制冷，导致延长了电池的充电时间的问题。
本实用新型通过以下技术方案实现：
一种双制冷的电池箱，包括外箱体、导热材料制成的内箱体，所述内箱体放在外箱体中，所述内箱体中放置有电池，相邻的电池之间放置有隔板，所述内箱体内腔经进油管、回油管连通储油罐，所述进油管上设有油泵，所述外箱体底部设置有散热孔，内腔底部设置有外散热槽，所述外散热槽通过管道连通制冷机构，所述管道上并联有支路，所述支路上依次设有风机、储能罐和截止阀，所述截止阀的控制器连接于电池的充电电路。
本实用新型的进一步方案是，所述储能罐上设置有压力开关，所述压力开关的输出端连接风机的电源线，当压力开关检测到储能罐中的压力高于预设的阈值时，风机停止。
本实用新型的进一步方案是，所述内箱体内腔底部设置有内散热槽，所述进油管连通内散热槽。
本实用新型的进一步方案是，所述隔板上设置有凸楞。
本实用新型与现有技术相比的优点在于：
一、电池放电时，制冷机构产生的一部分冷气存入储能罐，在电池充电时一起吹入箱体实现快速制冷，制冷机构以稳定的功率运行，不会延长电池的充电时间；
二、压力开关防止储能罐中压力过高形成安全隐患，而且可以防止风机过载损坏；
三、内散热槽将电池底部架空，与导热油之间有更大的接触面，更快地带走热量，而且使电池的热量分布更加均匀；
四、凸楞使电池之间形成流道，加速电池的冷却，防止热量积聚。
附图说明
图1为本实用新型的结构示意图。
