[0033] See also Figure 1 and 2Air outlets 7 are provided on both side walls of the protective shell 3. Heat dissipation components 8 are installed inside the two sets of air outlets 7 to dissipate the heat generated by the power supply motherboard body 2. The heat dissipation components 8 are arranged relative to the air outlets 7. By providing air outlets 7 on the side walls of the protective shell 3 and using them in conjunction with the heat dissipation components 8, the heat accumulated inside the protective shell 3 can be discharged, thereby achieving the effect of effectively dissipating heat from the power supply motherboard body 2, preventing the power supply motherboard body 2 and its components from overheating, ensuring their operational stability and extending their service life. Figure 1 and 4 The heat dissipation component 8 includes a mounting frame 801, which is fixedly embedded in the interior of the air outlet 7.
