As shown in FIG. 2, FIG. 3, FIG. 5 and FIG. 6, an embodiment of the present disclosure provides an outdoor unit of an air conditioner, including a heat exchanger 3 and a spray device 2.

The heat exchanger 3 includes at least one row of heat exchange tubes. As shown in FIG. 3, the heat exchanger includes two rows of heat exchange tubes, which are the first row of heat exchange tubes 31 and the second row of heat exchange tubes 32, respectively. The heat exchange tubes can be copper tubes or pipelines of other materials, and the heat exchange tubes are connected to each other.

The spray device 2 includes a spray part 21, and a plurality of rows of spray holes 211 are provided on the spray part 21, as shown in FIG. 2, including a first row of spray holes 212 and a second row of spray holes 213. The number of rows of spray holes 211 is greater than or equal to the number of rows of heat exchange tubes, so that each row of heat exchange tubes can be arranged opposite to at least one row of spray holes 211, so that one row of spray holes 211 can be directed to the heat exchanger 3, spray water at the corresponding row of heat exchange tubes to realize the cleaning of the heat exchange tubes.

For each row of heat exchange tubes, there is at least one row of spray holes 211 corresponding to the row of heat exchange tubes, where a row of spray holes 211 and a row of heat exchange tubes correspond to the row of spray holes 211 The sprayed water can reach the row of heat exchange tubes on the heat exchanger 3, or most of the water sprayed from the row of spray holes 211 can reach the row of heat exchange tubes on the heat exchanger 3. The row of heat exchange tubes on the heat exchanger 3 is cleaned. Since each row of heat exchange tubes has at least one row of corresponding spray holes 211, each row of heat exchange tubes on the heat exchanger 3 can be cleaned, thereby improving the cleaning effect of the heat exchanger 3, making the The heater 3 can be thoroughly cleaned.

As shown in FIG. 3, the extension direction of a row of spray holes 211 is the same as the extension direction of a corresponding row of heat exchange tubes, that is, each row of spray holes 211 is arranged along the direction of the corresponding row of heat exchange tubes, so that Therefore, every part in the extending direction of the row of spray holes 211 can correspond to every part in the extending direction of the row of heat exchange tubes, so that every part in the extending direction of the row of heat exchange tubes can be cleaned.

It should be noted that the number of spray holes 211 in a row of spray holes 211 is multiple, and the plurality of spray holes 211 are arranged along the same straight line or approximately the same straight line to form a row of spray holes 211. A row of spray holes 211 is a spray hole 211. A spray hole 211 has a larger length and extends along the extension direction of the corresponding heat exchange tube to form a slender spray hole 211.

The water inlet of the spray part 21 is arranged at the junction of two adjacent straight sections, and the junction is located at the supporting part. , So that the water pipe 22 extends vertically downward to fit on the support part.

An embodiment of the present disclosure also provides an air conditioner, including an outdoor unit of the air conditioner as in any one of the above-mentioned embodiments.

The air conditioner provided in the embodiments of the present disclosure includes the outdoor unit described in any one of the above embodiments, and therefore has all the beneficial effects of the outdoor unit described in any one of the above embodiments, and will not be repeated here.

The air conditioner also includes an indoor unit, and the outdoor unit is in communication with the indoor unit.

In summary, the outdoor unit provided by the present application and the water spray heat exchanger of the spray device can not only clean the heat exchanger and maintain the heat exchange capacity of the outdoor unit, but also can assist the heat exchanger of the outdoor unit to dissipate heat, improve energy efficiency, and save energy. The spray device does not affect the structure of the existing air conditioner, and does not affect the air intake and output of the existing air conditioner. The spray part is located in the gap between the top wall of the shell and the heat exchanger, and the water pipe utilizes the free position of the outdoor unit of the air conditioner, and there is no need to change the existing structure of the air conditioner.

The above description and drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments only represent possible changes. Unless explicitly required, the individual components and functions are optional, and the order of operations can be changed. Parts and features of some embodiments may be included in or substituted for parts and features of other embodiments. The embodiments of the present disclosure are not limited to the structures that have been described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is only limited by the appended claims.
