[0022] In response to the above problems, according to the instructions Figure 1-3 It can be seen that the present application discloses a distribution box shell with upper and lower layered heat dissipation. The electrical box uses a support frame 1 as the equipment skeleton. The support frame 1 is a rectangular structure frame. An active radiator 2 is installed on the top of the support frame 1.
