The inlet pipe 101 may be positioned at the bottom, middle, or top of the manifold 100 (as shown in the orientation of fig. 4), so as to deliver fluid into the manifold 100. In one embodiment, the inlet pipe 101 is located at the bottom of the flat pipe 200, and the inlet pipe 101 is opened with an opening 1011 on a side facing the top of the collecting main 100, so that the fluid can flow into the collecting main 100 from the inlet pipe 101 through the opening 1011.

The utility model provides a pressure manifold 100, including distributing at the inside reposition of redundant personnel baffle 10 of pressure manifold 100, reposition of redundant personnel baffle 10 includes: the fluid collecting device comprises a connecting part 11 connected with the collecting pipe 100, and a flow dividing part 12 connected with the connecting part 11 and used for dividing fluid in the collecting pipe 100, wherein a fluid passage opening 13 is formed between the periphery of the flow dividing part 12 and the inner wall of the collecting pipe 100. In the following description, the collecting main 100 is designated as collecting main 100 with the flow dividing baffle 10, i.e. collecting main 100 with the inlet pipe 101 in fig. 4.
