As shown in fig. 1, an embodiment of the first aspect of the present utility model provides an air duct board 100 of a refrigeration apparatus, including a frame 102 and a flexible portion 104. Wherein, the frame 102 is used for constructing the outer ring of the air duct board 100; the flexible portion 104 is connected to the frame 102 and is located in a space enclosed by the frame 102 to construct the air duct board 100.

If a barrier (such as a related art duct board) is present, wind may strike the barrier, and the sound generated by the wind flowing may be defined as wind sound B. It will be appreciated that when wind is flowing, the wind sound a with the obstruction is different from the wind sound B without the obstruction, and this difference may be considered to be due to the radiated noise caused by the obstruction.
