Abstract

A heat dissipation structure of a fan drive of an air conditioner outdoor unit, and an air conditioner outdoor unit are provided. A side plate of the air conditioner outdoor unit is disposed between a side plate of the fan drive and a baffle plate, and the side plate of the air conditioner outdoor unit clings to the side plate of the fan drive; a first air vent communicating with the outside of the air conditioner outdoor unit is provided on the side plate of the air conditioner outdoor unit; and a second air vent is provided on the baffle plate, the first air vent and the second air vent form an air duct between the side plate of the air conditioner outdoor unit and the baffle plate, and the second air vent enables the first air vent to communicate with an inner chamber of the air conditioner outdoor unite.

First claim

What is claimed is:

1. A heat dissipation structure of a fan drive of an air conditioner outdoor unit, comprising:
a side plate of the air conditioner outdoor unit; and
a baffle plate;
wherein the side plate of the air conditioner outdoor unit is disposed between a side plate of the fan drive and the baffle plate;
wherein a gap exists between the side plate of the air conditioner outdoor unit and the baffle plate;
wherein the side plate of the air conditioner outdoor unit clings to the side plate of the fan drive;
wherein the side plate of the air conditioner outdoor unit is provided with a first air vent that communicates with an outside of the air conditioner outdoor unit;
wherein a second air vent is provided on the baffle plate;
wherein the first air vent and the second air vent form an air duct between the side plate of the air conditioner outdoor unit and the baffle plate; and
wherein the second air vent enables the first air vent to communicate with an inner chamber of the air conditioner outdoor unit.

2. The heat dissipation structure according to claim 1 , further comprising a connecting plate connected to the baffle plate and the side plate of the air conditioner outdoor unit, the connecting plate comprising a first connecting sub-plate, a second connecting sub-plate, a third connecting sub-plate, and a fourth connecting sub-plate, wherein the baffle plate, the side plate of the air conditioner outdoor unit, the first connecting sub-plate, the second connecting sub-plate, the third connecting sub-plate, and the fourth connecting sub-plate form an enclosed hexahedron.

3. The heat dissipation structure according to claim 1 , wherein the baffle plate is parallel with the side plate of the air conditioner outdoor unit.

4. The heat dissipation structure according to claim 1 , wherein the side plate of the fan drive comprises a bottom cover, on which an element of the fan drive is installed.

5. The heat dissipation structure according to claim 1 , wherein the first air vent and the second air vent are separately located on two sides of a central axis of the side plate of the fan drive and perpendicular to the side plate of the fan drive.

6. An air conditioner outdoor unit, comprising the heat dissipation structure according to claim 1 .

7. The heat dissipation structure according to claim 1 , wherein the side plate of the air conditioner outdoor unit has a rectangular shape.

8. The heat dissipation structure according to claim 1 , wherein the baffle plate has a rectangular shape.

9. The heat dissipation structure according to claim 1 , wherein a size of the gap is determined according to an air volume and an air speed that are required.

10. An air conditioner outdoor unit comprising a heat dissipation structure, the heat dissipation structure comprising a side plate of the air conditioner outdoor unit disposed between a side plate of a fan drive and a baffle plate of the air conditioner outdoor unit, wherein a gap exists between the side plate of the air conditioner outdoor unit and the baffle plate, and the side plate of the air conditioner outdoor unit clings to the side plate of the fan drive, wherein the side plate of the air conditioner outdoor unit is provided with a first air vent that communicates with an outside of the air conditioner outdoor unit, and a second air vent is provided on the baffle plate, wherein the first air vent and the second air vent form an air duct between the side plate of the air conditioner outdoor unit and the baffle plate, and the second air vent enables the first air vent to communicate with an inner chamber of the air conditioner outdoor unit.

11. The air conditioner outdoor unit according to claim 10 , wherein the heat dissipation structure further comprises a connecting plate connected to the baffle plate and the side plate of the air conditioner outdoor unit, the connecting plate comprising a first connecting sub-plate, a second connecting sub-plate, a third connecting sub-plate, and a fourth connecting sub-plate, wherein the baffle plate, the side plate of the air conditioner outdoor unit, the first connecting sub-plate, the second connecting sub-plate, the third connecting sub-plate, and the fourth connecting sub-plate form an enclosed hexahedron.

12. The air conditioner outdoor unit according to claim 10 , wherein the baffle plate is parallel to the side plate of the air conditioner outdoor unit.

13. The air conditioner outdoor unit according to claim 10 , wherein the first air vent and the second air vent are separately located on two sides of a central axis of the side plate of the fan drive that is perpendicular to the side plate of the fan drive.

14. The air conditioner outdoor unit according to claim 10 , wherein the side plate of the air conditioner outdoor unit or the baffle plate has a rectangular shape.

15. The air conditioner outdoor unit according to claim 10 , wherein a size of the gap is determined according to an air volume and an air speed required.
