3. The electric box of an outdoor unit of an air conditioner according to claim 2, wherein the at least two support plates are disposed adjacent to a left end of the bottom wall and each support plate has a length direction oriented in a front-rear direction, and each support plate has a plurality of through-holes formed therethrough in a front-rear direction and in a left-right direction, the through-holes being spaced apart from each other in the front-rear direction.

4. The outdoor unit casing of claim 3, wherein the bottom wall comprises:

a first bottom wall, wherein the air inlet is formed on the first bottom wall;

the second bottom wall is connected to the left side of the first bottom wall through a connecting plate, the plane where the second bottom wall is located is higher than the plane where the first bottom wall is located, and the mounting opening is formed in the second bottom wall.

5. The electrical box of an outdoor unit of an air conditioner according to claim 3, wherein the penetration portion is formed as a penetration groove depressed downward from the upper surface of the corresponding support plate.

6. The outdoor unit casing of claim 5, further comprising a heat sink provided at the mounting opening, the heat sink comprising:

the first cooling fins are arranged at the upper ends of the at least two supporting plates and cover the mounting openings, and the first cooling fins and the control main board are separated by a preset distance in the vertical direction; and

a plurality of second heat radiating fins each provided on a lower surface of the first heat radiating fin and spaced apart from each other in a left-right direction.

7. The outdoor unit casing of claim 3, wherein the penetration portions are formed as through holes penetrating the respective support plates in a left and right direction.

8. The electrical box of an outdoor unit of an air conditioner as claimed in claim 3, further comprising a first outlet formed at a side wall of the chamber and located at a front side and/or a rear side of the mounting hole, wherein the cooling medium introduced into the chamber from the inlet cools the control main board and then flows out of the chamber through the first outlet.

9. The outdoor unit casing of claim 8, wherein the first louver is disposed at the first air outlet.

10. The electrical box of an outdoor unit of an air conditioner as claimed in claim 4, wherein the connecting plate defines a second outlet opening for discharging air downward, and a second louver is disposed at the second outlet opening, wherein the cooling medium introduced into the chamber from the air inlet can flow out of the chamber through the second outlet opening after cooling the control main board.

11. An outdoor unit of an air conditioner, comprising:

a mounting housing having a mounting cavity therein;

a partition plate disposed within the mounting chamber and separating the mounting chamber into a first chamber and a second chamber, wherein a pressure of air within the first chamber is lower than a pressure of air within the second chamber;

the electrical box of an outdoor unit for an air conditioner according to any one of claims 1 to 10, which is provided in the installation chamber, wherein the installation opening is formed in the first chamber and the intake opening is formed in the second chamber.

12. An air conditioner comprising the outdoor unit of claim 11.
