It is to be understood that the embodiments of the present application are not limited to the precise arrangements described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the embodiments of the present application is limited only by the following claims.

Referring to fig. 1 to 3, the embodiment provides an outdoor unit of an air energy water heater, including a housing 1 and a partition plate 4, an air inlet portion 17 and an air outlet portion 121 are disposed on the housing 1, an air duct is formed between the air inlet portion 17 and the air outlet portion 121, the partition plate 4 is disposed on the air duct and is used for dividing the air duct into an air inlet area and an air outlet area, an air outlet 41 for communicating the air inlet area and the air outlet area is connected to the partition plate 4, the area of the air outlet 41 is smaller than the area of the air outlet portion 121, where the air outlet portion 121 refers to a set of channels formed on the housing 1 and used for air exhaust, for example, a plurality of air vents 122.

Because the air volume entering the exhaust area through the air guide opening 41 and the air volume discharged from the exhaust area through the air outlet part 121 are equal, when the area of the air guide opening 41 is smaller than the area of the air outlet part 121, the air speed when the air passes through the air guide opening 41 is larger than the air speed when the air passes through the air outlet part 121, which reduces the air speed when the air passes through the air outlet part 121, and can avoid the interference of the air speed of the air outlet part 121 on the external environment due to the overlarge air speed; moreover, since the noise of the air outlet part 121 of the outdoor unit of the air-source water heater is positively correlated to the air speed of the air passing through the air outlet part 121, when the air passes through the air outlet part 121, the noise generated when the air passes through the air outlet part 121 is also reduced.
