Here, the fan wall 2 separates the control panel 3 and filter module 4 from the power module 5, capacitor module 6, inductor module 7, and heat sink 8, achieving effective heat dissipation. For example, the fan wall 2 can be made of metal plates.

[0033] In this embodiment, the control panel 3 is located above the filter module 4. The control panel 3 is fixed to the upper panel 11, and the filter module 4 is fixed to the lower panel 12. As an example, the fixing can be performed by means of studs.
