The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the utility model, as detailed in the appended claims.
Example 1
In preferred embodiment 1 of the present invention, there is provided an air conditioner, and in particular, fig. 1 shows an alternative structural schematic diagram of the air conditioner, as shown in fig. 1, including:
a heat exchanger 30;
an air grid, provided inside the heat exchanger 30, for ventilating the heat exchanger 30, comprising: the grid body 10 and the air deflector 20 arranged on the grid body 10; the air guiding interval of the air guiding plates 20 positioned at the upper part of the grid body 10 is larger than the air guiding interval of the air guiding plates 20 positioned at the lower part of the grid body 10.
In the above embodiment, an air conditioner for effectively improving heat exchange efficiency is provided, in which the air guide distance of the air guide plates on the upper portion of the grid body of the air grid is greater than the air guide distance of the air guide plates on the lower portion of the grid body, so that the resistance on the lower portion of the air grid is greater than the resistance on the upper portion of the air grid, and thus the air speed on the lower portion of the air grid is increased, the air flow rate on the lower portion of the heat exchanger is increased, the uniformity of the air speed distribution of the heat exchanger is improved, the heat exchange performance of the heat exchanger is improved, and the problem of poor overall performance of the heat exchanger is solved.
As shown in fig. 1, the air conditioner further includes a wind mechanism 40, and the wind mechanism 40 is disposed corresponding to the heat exchanger 30.
The wind guiding angle of the wind guiding plate 20 positioned at the upper part of the grid body 10 is smaller than that of the wind guiding plate 20 positioned at the lower part of the grid body 10, and the wind guiding angle is an included angle between the wind guiding plate 20 and a vertical downward direction. Therefore, the direction of the airflow entering the heat exchanger can be improved through different wind guide angles, so that the flow of the airflow at the lower part of the air grid is adjusted to be shorter, and the airflow flow rate is higher.
By applying the technical scheme of the utility model, the wind speed distribution on the surface of the heat exchanger is improved through the two functions, the effect of adjusting the wind speed distribution on the surface of the heat exchanger is achieved, the position with high wind speed of the conventional outdoor unit is reduced, and the position with low wind speed is increased, so that the overall wind field cooperation of the heat exchanger is balanced, and the heat exchange capacity of the heat exchanger is improved.
It should be noted that the above-mentioned wind guide angle guides the included angle between the center line of the wind board and the vertical downward direction; the wind guide distance refers to the distance between the adjacent wind guide plates and the connection point of the grid body 10.
As an alternative embodiment, as shown in fig. 2, according to theoretical simulation calculation and experimental verification, in the present embodiment, the wind grid is preferably divided into an upper part and a lower part, the wind deflectors 20 include a first wind deflector group 20a and a second wind deflector group 20b, the first wind deflector group 20a is installed on the upper part of the grid 10, and the second wind deflector group 20b is installed on the grid 10 and is located below the first wind deflector group 20 a. The air guide pitch of the first air guide plate group 20a is greater than the air guide pitch of the second air guide plate group 20b, and the air guide angle of the first air guide plate group 20a is smaller than the air guide angle of the second air guide plate group 20 b. By applying the embodiment, the effect of uneven wind speed at the upper part and the lower part of the heat exchanger can be improved only by installing the air guide plates with two air guide intervals and air guide angles. Specifically, in the present embodiment, the distribution width of the first air guide plate group 20a is m, the distribution width of the second air guide plate group 20b is n, and m/n is 1 to 1.4. Preferably, the wind speed uniformity can be more effectively adjusted by setting m/n to 1.2 according to the blockage of the components at the lower part of the conventional air conditioner. The height of the grid body 10 is s, and m + n is less than or equal to s. Wherein the height of s should not be greater than the heat exchanger height.
Through tests, the air guide angle is 80-150 degrees. Preferably, the wind guide angle of the first wind guide plate group 20a is 110 ° and the wind guide angle of the second wind guide plate group 20b is 143 °.
Through tests, the air guide distance is 1 cm-3 cm. Preferably, the air guide pitch of the first air guide plate group 20a is 2.3cm, and the air guide pitch of the second air guide plate group 20b is 1.5 cm.
Fig. 3 is a schematic view of airflow distribution of an air conditioner in the prior art, in which the air grid of the above embodiment is applied to the air conditioner, and fig. 4 is a schematic view of airflow distribution of the air conditioner in the present invention.
As another embodiment not shown in the drawings, in this embodiment, the wind guide pitch of the wind guide plate 20 is decreased in order from the upper end of the grid 10 to the lower end of the grid 10. More preferably, the wind guide angle of the wind guide plate 20 is increased from the upper end of the grid 10 to the lower end of the grid 10. This embodiment is more difficult and costly to install than the above-described embodiments, but may also have the above-described effect of adjusting the wind speed distribution more uniformly.
In addition, in the solution of the present invention, as shown in fig. 5, both ends of the air deflector 20 are rotatably mounted on the grid 10 through a rotating shaft. And the rotating mechanism 50 is in driving connection with the air deflector 20 and is used for driving the air deflector 20 to rotate.
