And air outlet of casing 12 is located at the side wall 15 corresponding to the long side of rectangle.
It when detection module is detected, needs to reach certain ventilation quantity, it is accurate to measure.Therefore, shell air inlet
11 and air outlet of casing 12 size it is more big more be conducive to measure.If but 12 ruler of shell air inlet 11 and air outlet of casing
Very little conference excessively causes 1 strength reduction of casing assembly.Therefore in order to expand ventilation quantity as possible, while ensure that casing assembly 1 has again
Appropriate intensity recommends shell air inlet 11 and/or air outlet of casing 12 to include several sub- air ports.If each sub- air port arrangement is excessively
It is intensive, it can also influence intensity, and each side wall 15 fills enough along the space of the length direction of its orthographic projection on a projection plane
Point.Therefore, further, in order to more efficiently ensure the intensity of casing assembly 1, several sub- air ports are along side wall 15 where it
The length direction of orthographic projection on a projection plane is arranged successively.Specifically, the present embodiment shell air inlet 11 and shell go out
Air port 12 respectively includes four sub- air ports, the length direction of orthographic projection of each sub- air port along side wall 15 where it on a projection plane according to
Secondary arrangement.
