The housing body 10 has an internal cavity 11 for mounting battery components 60 and a cooling channel 12 for cooling the battery components 60. The cavity 11 has mounting gaps 13 on both sides for wiring to pass through, and these gaps extend along the arrangement direction of the battery components 60. Two discharge terminals 20 are fixedly mounted at the ends of the housing body 10 and correspond to the mounting gaps 13. One end of each discharge terminal 20 is located inside the cavity 11, and the other end is located outside the housing body 10. The two discharge terminals 20 are used to connect two connected battery components 60. Two connecting pipes 30 are also mounted at the ends of the housing body 10. Both connecting pipes 30 are connected to the cooling channel 12 and are used for the inflow and outflow of a low-temperature medium into and from the cooling channel.

[0032] Compared with the prior art, the dump truck power battery C-type housing provided by this utility model has the following advantages: During use, the housing body 10 has an internal receiving cavity 11, with installation spacing 13 on both sides of the receiving cavity 11.
