[0030] Please refer to Figure 3 and Figure 4 , a plurality of heat dissipation fins 12 are installed at equal intervals on the outer wall of the inverter body 1, and the heat dissipation fins 12 are designed to be inclined, which is beneficial to the heat generated by the inverter body 1 during operation to be dissipated to the gap between the inverter body 1 and the outer shell 2 through the heat dissipation fins 12, and the inclined design of the heat dissipation fins 12 not only increases the contact area of air flow, but also guides the hot air to flow in a more efficient way, thereby accelerating the dissipation of heat.
[0031] Please refer to Figure 1 - Figure 6 , the fan cover 22 is installed on the end of the outer shell 2 away from the inverter body 1, and the heat dissipation net 21 is installed on the end of the outer shell 2 close to the inverter body 1, so that the fan 3 is protected from direct interference from the external environment, and at the same time, the hot air accelerated by the fan 3 can smoothly pass through the heat dissipation net 21 to be discharged outside the inverter body 1, further improving the heat dissipation efficiency.
[0032] Please refer to Figure 1 - Figure 6 , the first guide plate 11 is installed on the end of the inverter body 1 close to the fan cover 22, and the first guide plate 11 is designed to be inclined, which is beneficial to guide part of the wind generated by the fan 3 through the first guide plate 11 and blow to the gap between the inverter body 1 and the outer shell 2, thereby quickly taking away the accumulated heat and reducing the overall temperature inside the inverter.
[0033] Please refer to Figure 1 - Figure 6 , the height of the second guide plate 31 is greater than the height of the fan 3, and the width of the second guide plate 31 is equal to the width of the inner wall of the outer shell 2, which is beneficial to concentrate and accelerate part of the wind generated by the fan 3 to blow to the heat dissipation fin 12 in the gap between the inverter body 1 and the outer shell 2, thereby enhancing the strength and directionality of the wind flow.
