Specifically, the air duct adopts a flat structure to increase the width and reduce the thickness dimension, so that arrangement and assembly can be completed by utilizing the interval in the shell.
In some embodiments, the air duct spans over the heat exchanger. Specifically, a certain space is reserved between the upper part of the heat exchanger and the top of the shell, and the air duct is arranged by utilizing the space above the heat exchanger.
And to the whole shape of wind channel, it is the structure of type of falling U, and is specific, the wind channel is including the first air supply section 51, second air supply section 52 and the third air supply portion 53 that connect gradually, first air supply section is arranged back in the shell and with the air intake intercommunication, second air supply section is arranged top in the shell, third air supply portion is arranged front in the shell and towards the fan direction extends.
The first air supply section extends downwards from the upper part of the heat exchanger towards the direction of the air inlet, so that the first air supply section is communicated with the air inlet. And outside air enters the first air supply section through the air inlet and is transmitted. The second air supply section is arranged at the top of the heat exchanger to convey airflow, a smoke collecting hood 31 is arranged above the heat exchanger in a normal condition, and a smoke exhaust tube 32 extending out of the shell is arranged on the smoke collecting hood 31; in order to avoid the smoke exhaust tube 32, the air duct comprises two second air supply sections which are arranged side by side, and the smoke exhaust tube is positioned between the two second air supply sections. And for the third air supply section, the third air supply section extends downwards from the upper part of the heat exchanger towards the direction of the fan so as to convey air flow to the fan.
By arranging the air duct in the shell, outside air is smoothly conveyed to the air inlet side of the fan through the air duct, and noise generated between airflow entering the shell and relevant parts inside the shell is reduced; the sectional design of the air duct can fully utilize the spaces on the front side, the rear side and the top of the shell to install the air duct, and the flat air duct can fully utilize the limited space in the shell to meet the conveying requirement of the air supply quantity.
In order to more effectively reduce the noise of the fan, the air duct and the noise reduction assembly may be configured at the same time.
As shown in fig. 2 and 3, the noise reduction assembly may be integrated into the air duct as a module, and the air duct is connected to the inlet of the fan through the noise reduction assembly. Therefore, the outside air enters the air duct through the air inlet, and the air flow is further subjected to noise reduction treatment through the noise reduction assembly in the process of flowing to the fan from the air duct, so that the noise reduction effect is improved to the maximum extent. Because the noise reduction assembly is arranged at the outlet of the air duct, under the action of the fan, part of air in the shell can enter the fan through the noise reduction holes of the noise reduction assembly to play a role in assisting air supply.
Alternatively, as shown in fig. 6 and 7, the noise reduction assembly and the air duct are designed separately, the noise reduction assembly is directly mounted on the fan, and the outlet of the air duct is located at one side of the noise reduction assembly. Outside air enters the air duct through the air inlet, and after the air flow is output from the air duct, the air flow is subjected to noise reduction treatment through the noise reduction assembly and then is sucked into the fan, so that the noise reduction effect is improved to the maximum extent.
