The present application provides an air conditioner outdoor unit. Referring to
In the air conditioner outdoor unit 100 of the present application, the heat exchanger assembly 140 is arranged to extend along a side wall of the cabinet 110, and at least part of the side wall is arranged opposite to the compressor assembly 130. The air inlet 111 is arranged at a position of the side wall that is opposite to the heat exchanger assembly 140. When an airflow outside the cabinet 110 enters the cabinet 110 through the air inlet 111 and exchanges heat with the heat exchanger assembly 140, it flows toward the air outlet 112 of the cabinet 110 under the action of the fan 120, and is discharged out of the cabinet 110 from the air outlet 112.
In the air conditioner outdoor unit 100 of the present application, the compressor assembly 130 is arranged inside the cabinet 110, and a minimum distance between the compressor assembly 130 and the fan 120 is L. When an airflow is formed at the air inlet 111 on the side wall arranged opposite to the compressor assembly 130, the compressor assembly 130 will interfere with the airflow that has entered the cabinet 110. The air conditioner outdoor unit 100 of the present application reduces the influence of the compressor assembly 130 on the airflow circulation by setting forth the distance between the compressor assembly 130 and the fan 120. Increasing the distance between the compressor assembly 130 and the fan 120 appropriately is advantageous for the airflow inside the cabinet 110 to flow toward the air outlet 112, thus weakening the stagnation region which is formed by the airflow near the compressor assembly 130 and which hinders the flow of the airflow.
In the air conditioner outdoor unit 100 of the present application, since the compressor assembly 130 is arranged opposite to the side wall where the heat exchanger assembly 140 is arranged, when the airflow enters the cabinet 110 through the air inlet 111 on the side wall and flows toward the air outlet 112 after exchanging heat with the heat exchanger assembly 140, part of the airflow will interfere with the compressor assembly 130. On one side of the compressor assembly 130 that is opposite to the air outlet 112, a stagnation region of the airflow will be formed, which affects the circulation of the airflow inside the cabinet 110. The air conditioner outdoor unit 100 of the present application can reduce the influence of the above stagnation region of the airflow on the circulation of airflow by appropriately increasing the distance between one side of the compressor assembly 130 and the air outlet 112 arranged opposite to it, thereby enhancing the circulation of airflow inside the cabinet 110, which is advantageous for improving the heat exchange efficiency of the air conditioner outdoor unit 100.
The air conditioner outdoor unit 100 of the present application can reduce the influence of the stagnation region formed on one side of the compressor assembly 130 on the circulation of airflow by appropriately increasing the distance between the compressor assembly 130 and the air outlet 112, and also can further reduce the pressure pulsation of the airflow field, making the flow of the circulating airflow smoother and minimizing the pulsation effect of the stagnation region on one side of the compressor assembly on the circulating airflow. Therefore, the air conditioner outdoor unit 100 of the present application operates more smoothly, has a higher heat exchange efficiency, and improves user comfort.
With reference to
It should be noted that in the air conditioner outdoor unit 100 of the present application, since the fan 120 is arranged at the air outlet 112, in order to reduce the influence of the airflow stagnation region on one side of the compressor assembly 130 on the circulating airflow, the distance between the compressor assembly 130 and the air outlet 112 arranged opposite to it can be appropriately increased, and the distance between the compressor assembly 130 and the fan 120 opposite to it can also be appropriately increased, so as to weaken the influence of the stagnation region on one side of the compressor assembly 130 on the circulation of airflow between the air inlet 111 and the air outlet 112 and even on the operating efficiency of the whole air conditioner outdoor unit 100.
In an embodiment of the present application, the compressor assembly 130 is arranged at a bottom wall of the cabinet 110, a height of the compressor assembly 130 is H, and the minimum distance between the compressor assembly 130 and the fan 120 is L; in the height direction of the compressor assembly 130, the maximum size of the heat exchanger assembly 140 on the side wall of the cabinet 110 is S, where H+L>S. For example, a highest position of the heat exchanger assembly is set below a lowest end of the fan, or the entire heat exchanger assembly is arranged at a position opposite to a side part of the compressor assembly. In this embodiment, the distance L between the fan 120 and the compressor assembly 130 can reduce the influence of the stagnation region, which is generated due to the interference of the compressor assembly 130 with the airflow that has entered the cabinet 110, on the circulating airflow. Since the distance between the fan 120 and the compressor assembly 130 is larger than a difference between the maximum size of the heat exchanger assembly 140 and the height of the compressor assembly 130, the airflow can flow sufficiently in a space between the compressor assembly 130 and the fan 120, thus reducing the influence of the stagnation region on the airflow and also reducing the influence of pressure pulsation of the airflow on the work done by the fan 120.
In the air conditioner outdoor unit 100 provided in this embodiment, the position of the air outlet 112 of the cabinet 110 can be set according to actual needs. For example, the air outlet 112 can be arranged at the side wall of the cabinet 110, or the air outlet 112 and the air inlet 111 can be arranged at two opposite side walls respectively, or the air inlet 111 and the air outlet 112 can be staggered and arranged at different positions. The air inlet 111 can also be arranged at a lower part of the cabinet 110, and the air outlet 112 can be arranged at an upper part of the cabinet 110 or at the top of the cabinet 110.
In the air conditioner outdoor unit 100 of this embodiment, the heat exchanger assembly 140 can be arranged to extend upward from the bottom of the side wall of the cabinet 110. When the height of the heat exchanger assembly 140 is lower than that of the compressor assembly 130, the air outside the cabinet 110 enters the cabinet 110 through the air inlet 111 of the cabinet 110 and flows in a direction toward the air outlet 112 from one side of the compressor assembly 130. Since the compressor assembly 130 is arranged opposite to the side wall at the air inlet 111 of the cabinet 110, the airflow that has entered the cabinet 110 will be interfered or hindered by the compressor assembly 130; when the height of the heat exchanger assembly 140 is higher than that of the compressor assembly 130, and the maximum size of the heat exchanger assembly 140 is smaller than the sum of the height of the compressor assembly 130 and the distance between the fan 120 and the compressor assembly 130, part of the airflow that has entered the cabinet 110 will be interfered by the compressor assembly 130, while the other part of the airflow that has entered the cabinet 110 will directly flow toward the air outlet 112 without interfering with the compressor assembly 130. In the air conditioner outdoor unit 100 of this embodiment, a minimum distance L is set between the fan 120 and the compressor assembly 130, so that there is sufficient space between the compressor assembly 130 and the fan 120 opposite to it. The airflow flows sufficiently in the above space, reducing the interference of the compressor assembly 130 with part of the airflow inside the cabinet 110. When the fan 120 rotates to do work, it will not be affected by the airflow stagnation region on one side of the compressor assembly 130.
In an embodiment of the present application, the fan 120 is arranged inside the cabinet 110 and located between the air outlet 112 of the cabinet 110 and the compressor assembly 130. In the air conditioner outdoor unit 100 of this embodiment, an air outflow side of the fan 120 is arranged opposite to the air outlet 112 of the cabinet 110. Under the action of the rotation of the fan 120, the airflow flows from the air inlet 111 to the air outlet 112 inside the cabinet 110. An air inflow side of the fan 120 can face the compressor assembly 130, and the minimum distance between the fan 120 and the compressor assembly 130 is L. By combining the above different embodiments of the present application, it can be seen that by setting forth the distance between the fan 120 and the compressor assembly 130, the interference of the compressor assembly 130 with the airflow can be reduced, the pressure pulsation effect of the stagnation region formed on one side of the compressor assembly 130 on the airflow can be reduced, and the influence of the airflow stagnation region on the work done by the fan 120 can also be reduced.
In other embodiments of the present application, the fan 120 can be set as an independent component, which is arranged outside the cabinet 110 and located at the air outlet 112 of the cabinet 110. The air inflow side of the fan 120 is arranged opposite to the air outlet 112 of the cabinet 110. Under the action of the fan 120, the air outside the cabinet 110 enters from the air inlet 111 of the cabinet 110 and flows toward the air outlet 112.
In order to better utilize the fan 120, an air guide cover 160 can also be provided on the outside of the fan 120.
In an embodiment of the present application, the minimum distance L between the fan 120 and the compressor assembly 130 is the distance between a fan blade of the fan 120 and the top of the compressor assembly at a position away from the air outlet 112 of the cabinet 110. The air conditioner outdoor unit 100 of this embodiment is suitable for the implementation where the fan 120 is arranged inside the cabinet 110, especially for the implementation where the air inflow side of the fan 120 is arranged opposite to one side of the compressor assembly 130. The minimum distance between the fan 120 and the compressor assembly 130 is L. By appropriately increasing the distance between the fan 120 and the compressor assembly 130, the influence of the airflow stagnation region formed on one side of the compressor assembly 130 on the work done by the fan 120 can be reduced.
In an embodiment of the present application, the air outlet 112 of the cabinet 110 is arranged at the top of the cabinet 110, and an airflow circulation path is formed between the air inlet 111 and the air outlet 112. Part of the compressor assembly 130 is located at the airflow circulation path. In the air conditioner outdoor unit 100 of this embodiment, the cabinet 110 adopts the form of top air outflow and side air inflow. In the limited space of the cabinet 110, the compressor assembly 130 interferes with part of the airflow, and an airflow stagnation region is formed in the upper region of the compressor assembly 130. This stagnation region can suppress the work done by the fan 120, cause pressure pulsation of the airflow, and also produce certain noise in the flow field of the airflow, which will affect the smoothness of the operation of the air conditioner outdoor unit 100. In the air conditioner outdoor unit 100 of the present application, by appropriately increasing the distance between the fan 120 and the compressor assembly 130, the above problems are solved.
Referring to
In an embodiment of the present application, the heat exchanger assembly 140 extends along the side wall of the cabinet 110 and forms an accommodation space 141, and the compressor assembly 130 is arranged in the above accommodation space 141. In the air conditioner outdoor unit 100 of this embodiment, the heat exchanger assembly 140 is arranged to extend along the side wall of the cabinet 110, so that the large side wall area of the cabinet 110 can be used to arrange the heat exchanger assembly 140, and the heat exchange efficiency of the heat exchanger assembly 140 can be improved. At the same time, the heat exchanger assembly 140 encloses the accommodation space 141, so that the limited internal space of the cabinet 110 can be used to arrange the compressor assembly 130, making the overall structure more compact.
Referring to
In an embodiment of the present application, the air conditioner outdoor unit 100 further includes an air guide cover 160, which is formed with an air guide channel. The fan blade of the fan 120 is rotatably arranged in the air guide channel. When the fan 120 is arranged inside the cabinet 110, the air guide cover 160 and the fan 120 together are arranged inside the cabinet 110. When the fan 120 is arranged outside the cabinet 110, the air guide cover 160 and the fan 120 together are arranged outside the cabinet 110 as an assembly of the fan 120. In both the above arrangements, the air guide cover 160 can guide air for the fan 120 and can also suppress the formation of noise in the airflow field.
In the above different embodiments of the present application, the compressor assembly 130 includes a compressor, a tank group, and a pipeline connecting the compressor and the tank group. The compressor assembly 130 has a large volume and can hinder the circulation of airflow inside the cabinet 110. Therefore, in the air conditioner outdoor unit 100 of the present application, the positional relationship between the fan 120, the compressor assembly 130, and the heat exchanger assembly 140 is improved, so that the airflow inside the cabinet 110 becomes more stable.
The present application also provides an air conditioner, which includes the air conditioner outdoor unit 100 according to any one of the above embodiments.
Described above are only some specific embodiments of the present application, but the scope of protection of the present application is not limited to this. Any changes or replacements that can be easily conceived by those skilled in the art within the technical scope disclosed by the present application should be covered within the scope of protection of the present application. Therefore, the scope of protection of the present application should be accorded with the scope of protection of the claims.
