Therefore, the heat dissipation capability of the case is important for the chassis.

Some existing cases generally rely on fans to dissipate heat, and for scenes with high heat dissipation requirements, such as a host of a locomotive integrated wireless communication device (CIR), the effect of using a common case to dissipate heat is not ideal.

However, when the fan auxiliary cooling device (such as a fan) is damaged, the whole B-frame machine can be halted in a short time. Thereby causing the integrated wireless communication device of the locomotive to lose function.
