Example one
The utility model discloses air condensing units fan casing, as shown in FIG. 4, the side that circumference rib 1 is close to air condensing units fan casing center is second side 14, and second side 14 is sunken to the direction of keeping away from air condensing units fan casing center along the middle part of air condensing units fan casing axis direction and forms the curved surface. Similar to the first side 11, the second side 14 is tangent to the air outlet end 13 (in fig. 4, dotted line c)3The direction shown) and the axis of the fan housing of the outdoor unit of the air conditioner is smaller than the tangent line (in fig. 4, the dotted line c) of the air inlet end 12 of the second side surface 143The direction shown) to the axis of the fan housing of the outdoor unit of the air conditioner. The tangent line of the second side surface 14 forms a certain included angle with the axis of the fan cover of the air conditioner outdoor unit, and the included angle between the tangent line of the second side surface 14 and the axis of the fan cover of the air conditioner outdoor unit is gradually reduced from the air inlet end 12 of the circumferential ribs 1 to the air outlet end 13 of the circumferential ribs 1 along the axis of the fan cover of the air conditioner outdoor unit. When the air current flows along the second side surface 14, the second side surface 14 can guide the air current to deflect towards the center of the fan cover of the air conditioner outdoor unit, the second side surface 14 and the first side surface 11 cooperate to guide and change the air current direction entering the air inlet end 12 of the circumferential ribs 1 together, the divergence of the air current in the radial direction of the fan cover of the air conditioner outdoor unit is reduced, the air current is more concentrated and is discharged from the fan cover of the air conditioner outdoor unit along the axial direction of the fan cover of the air conditioner outdoor unit, therefore, the air current is more easily discharged from the mounting cavity of the air conditioner outdoor unit, and the heat exchange capacity of the air.

It should be noted that the principle of the change of the airflow direction guided by the first side 12 and the second side 14 is different; the first side 11 changes the direction of the air flow by using the coanda effect of the fluid, and the second side 14 changes the direction of the air flow by using the air channel formed by the second side 14.
Example two
The utility model discloses air condensing units fan casing, as shown in FIG. 5, the side that circumference rib 1 is close to air condensing units fan casing's center is second side 14, and second side 14 is the plane along air condensing units fan casing's axis direction. It should be understood that "the side 14 is a plane along the axial direction of the fan cover" specifically means that, as shown in fig. 5, the second side 14 extends along a straight line in the axial direction of the fan cover; the second side 14 itself has an extension in the radial direction of the fan cover of the outdoor unit of the air conditioner and an extension in the axial direction of the fan cover of the outdoor unit of the air conditioner; the second side surface 14 is a plane when viewed along the axial direction of the fan cover of the outdoor unit of the air conditioner. Compared with the first embodiment, the second side surface 14 is recessed along the middle of the axial direction of the fan cover of the outdoor unit of the air conditioner to a direction away from the center of the fan cover of the outdoor unit of the air conditioner to form a curved surface, and the second side surface 14 extends along a curve in the axial direction of the fan cover of the outdoor unit of the air conditioner. The utility model discloses air condensing units fan casing, second side 14 are the straight line along air condensing units fan casing's axial extending direction, its simple structure, low in manufacturing cost.
When the second side surface 14 is a plane along the axial direction of the fan cover of the outdoor unit of the air conditioner, as shown in fig. 5 and 6, an included angle α is formed between the second side surface 14 and the axial line of the fan cover of the outdoor unit of the air conditioner, and an included angle β is formed between the airflow entering the air inlet end 12 of the circumferential rib 1 and the axial line of the fan cover of the outdoor unit of the air conditioner, wherein α is not more than β, when α is less than β, the second side surface 14 and the first side surface 11 guide and change the airflow direction together, the airflow direction deflects towards the center of the fan cover of the outdoor unit of the air conditioner from the air inlet end 12 to the air outlet end 13 of the circumferential rib 1, the deflection angle of the airflow is equal to the included angle formed between the tangential direction of the air inlet end 12 of the second side surface 14 and the tangential direction of the air outlet end of the second side surface 14, that is (β - α), when α is β, the extending direction of the second side surface 14 has the same as the tangential direction of the airflow.
It should be noted that the reason why the second side surface 14 is not directly arranged along the axial direction of the air conditioner outdoor unit fan cover is to reduce the resistance of the second side surface 14 to the airflow. If the extending direction of the second side surface 14 is set to be the same as the axial direction of the air conditioner outdoor unit fan cover, although the air flow can be made to flow along the axial direction of the air conditioner outdoor unit fan cover to the maximum extent. However, when the incoming airflow diverges greatly in the radial direction of the fan cover of the outdoor unit of the air conditioner, when the airflow enters the circumferential ribs 1, an included angle formed between the airflow and the second side surface 14 is large, and the resistance of the second side surface 14 to the airflow is large, so that the speed of the airflow is affected, and the airflow is not beneficial to being discharged from the outdoor unit. Therefore, the size of the included angle between the second side surface 14 and the axis of the fan cover of the outdoor unit of the air conditioner needs to be specifically adjusted according to the size of the circumferential component of the airflow rotating along the circumferential direction of the fan cover of the outdoor unit of the air conditioner.
The airflow generated by the axial flow fan has divergence along the radial direction of the fan cover of the outdoor unit of the air conditioner when passing through the fan cover of the outdoor unit of the air conditioner. In order to reduce the resistance of the circumferential ribs 1 to the air flow when the air flow passes through the circumferential ribs 1.

The radial ribs 2 and the circumferential ribs 1 are mutually crossed, and the radial ribs 2 and the circumferential ribs 1 form a net structure, so that sundries can be prevented from penetrating through the fan cover and entering the outdoor unit of the air conditioner.
It should be noted that the radial ribs 1 and the circumferential ribs 2 are formed by injection molding, and compared with a metal material, the plastic material has lower cost; and because the surface of radial rib 1 is the curved surface, the processing and manufacturing difficulty of the injection molding processing mode is lower. It should be noted that injection molding only provides a relatively simple and low-cost processing method, and the fan cover manufactured by other technical schemes also belongs to the protection scope of the present invention.
On the other hand, the embodiment of the utility model provides an air conditioner is still provided, including air condensing units, the last air outlet that is equipped with of air condensing units, air outlet department are equipped with foretell air condensing units fan casing.
The utility model discloses an air conditioner, compare in traditional air conditioner, because set up foretell air condensing units fan casing in air condensing units air outlet department, the air condensing units combustion air current more concentrated along the axis direction discharge of air condensing units fan casing, and then reduce the energy and the air loss of the air current flow in-process, and when reducing the installation cavity of air current discharge air condensing units, the area of contact of the grid of air current and air condensing units's installation cavity, make the air current discharge from air condensing units's installation cavity more easily, and then promote the heat transfer ability of air conditioner.
