技术领域Technical Field
本申请涉及电池技术领域，尤其涉及一种液冷装置及电池包。The present application relates to the field of battery technology, and in particular to a liquid cooling device and a battery pack.
背景技术Background technique
电池包包括箱体和设于箱体内的电芯以及冷却板，冷却板的通过接头与外部整车端的冷却设备连接，向冷却板内供应冷却水以对电芯进行冷却。现有技术中，快插公接头与冷却板焊接且均设置在箱体内部，接头与整车端冷却设备的进、出水口通过尼龙管路与快插公接头进行快插连接。The battery pack includes a box body, a battery cell and a cooling plate arranged in the box body. The cooling plate is connected to the cooling equipment on the external vehicle end through a joint, and cooling water is supplied to the cooling plate to cool the battery cell. In the prior art, the quick-plug male connector is welded to the cooling plate and both are arranged inside the box body. The connector and the water inlet and outlet of the cooling equipment on the vehicle end are quickly connected through nylon pipes and quick-plug male connectors.
然而，由于快插公接头设于箱体内部，导致拆装的次数存在限制，尼龙管路与快插公接头经过多次插拔后存在密封失效的风险，产生漏液，从而导致电池包失效的风险；另外，快插公接头会占用箱体内部空间，对箱体内部空间要求较高。However, since the quick-connect male connector is located inside the box, the number of times it can be disassembled and assembled is limited. After multiple insertions and removals, there is a risk of sealing failure between the nylon tube and the quick-connect male connector, resulting in leakage, which in turn leads to the risk of failure of the battery pack. In addition, the quick-connect male connector occupies space inside the box, placing high demands on the space inside the box.
