The invention belongs to the field of new energy vehicles. The invention particularly discloses a shell and a battery pack. The shell is provided with an accommodating cavity for accommodating the battery cell module and a liquid cooling channel for cooling the battery cell module. A water inlet flow channel and a water outlet flow channel are formed in the side wall of the shell; one end of the water inlet flow channel is communicated with an external water inlet port, the radial sectional area of the water inlet flow channel is larger than that of the water inlet port, the water outlet flowchannel comprises a plurality of branch flow channels, a cooling flow channel is formed in the bottom of the shell, and the water inlet flow channel, the cooling flow channel and the water outlet flowchannel are sequentially communicated to form a liquid cooling channel. And the liquid cooling channel and the shell are integrally formed, so that the space occupied by the liquid cooling channel isreduced. The water inlet flow channel and the water outlet flow channel jointly reduce the pressure drop of cooling liquid flowing through the liquid cooling channel.
本发明属于新能源汽车领域。具体公开了一种壳体及电池包。其中壳体具有用于容纳电芯模组的容纳腔和冷却电芯模组的液冷通道。壳体的侧壁开设有进水流道和出水流道,进水流道的一端与外部的进水端口连通,且进水流道的径向截面面积大于进水端口的径向截面面积,出水流道包括多个分支流道,壳体的底部开设有冷却流道,进水流道、冷却流道和出水流道依次连通,以形成液冷通道。液冷通道与壳体一体化成型,减少了液冷通道占用的空间。进水流道和出水流道共同降低了流过液冷通道的冷却液的压降。
