The geometry of the inlet one 17 and the inlet three 19 may be rectangular or non-rectangular, such as circular or other multi-end arc shape, and the present embodiment is preferably rectangular. The inlet one 17, the inlet two 18, the inlet three 19 and the inlet four 20 are all rectangular in geometry.
The first inlet 17 is opposite to the outlet 13, the second inlet 18 is opposite to the outlet 14, the third inlet 19 is opposite to the outlet 15, and the fourth inlet 20 is opposite to the outlet 16.
