Specific implementation mode
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As shown in Figure 1, a kind of car air inlet silencer 10, the silencer is by cylindrical metal shell body 20 and cylinder
The rectangular layering kernel 30 of body is constituted, and the rectangular layering kernel 30 of cylinder is by the first contour cylinder 41 and the second cylinder
42 are alternately formed by stacking, and first cylinder, 41 and second cylinder 42 is all hollow and thin-walled structure, along axis inside cylinder
