MF-DS Β· MF-BS

Manifold

The manifold is a water distribution and collection header for server liquid cooling, connecting the CDU to the cold plates of rack-mounted servers. It is available in quick-disconnect and blind-mate versions. It can be integrated into or externally connected to the cabinet frame, with branch flow selected according to server heat dissipation requirements.

Product features

  • 304 stainless-steel main body, air vent and related components; EPDM hoses for corrosion resistance.
  • Pipeline design targets branch-flow non-uniformity below 10%.
  • Customized for server layout and multiple cabinet mounting methods.
  • In-cabinet installation operable by one person.
  • Server branch connectors use drip-free quick connections for installation and maintenance.
  • Deionized-water rinsing, high-temperature gas drying and transport under 1.5 bar gas pressure for cleanliness.

Reference conditions & selection notes

  • Slide 7 places branch configuration under the printed Material column and material under Number of Branches; the table above uses labels matching the actual cell content. Its printed Working Pressure column contains fluid names; no numeric working pressure is supplied.
  • The slide 7 model series has standard 16-inlet/16-outlet configuration; slides 29–30 give separate typical engineering guidance of 20 branches. The typical guidance is not a rating for every MF model.
  • The 30 Γ— 30 / 40 Γ— 40 / 50 Γ— 50 source table does not print a dimension unit. The 33 Γ— 33 mm example comes from slide 30.
