Water Cooled Plate Flow Divider Liquid Cold Plate Fitting Shunt Accessory Component

Water Cooled Plate Flow Divider Liquid Cold Plate Fitting Shunt Accessory Component
Product Specifications
Model: OMWH12-H-6-IR-A
Version: V1.0
Application Scenarios: Electronic liquid cooling systems, high-power industrial power supplies, charging pile BMS, industrial control current sensing
Product Overview
This product is a customized Kelvin lead-type power shunt resistor featuring an integrated welding structure of high-conductivity copper alloy resistive element and electrolytic copper bracket.
Designed with low resistance, high current carrying capacity, and high-precision sampling capabilities, it is specifically engineered for industrial current sensing at hundreds of amperes, suitable for harsh high-temperature and high-vibration working conditions.
  • Welding: Bracket and copper alloy resistive element welded on non-sheared surfaces; no gaps, cold joints or false welds. Pickling before welding, passivation after welding.
  • Appearance: Flat, smooth and uniform surface; no burrs, burns, slag, contamination or cracks.
  • Encapsulation: Welded areas covered with transparent heat-shrink tube, tight and wrinkle-free. Leads firmly fixed, color coding clear.
Test & Acceptance Criteria
  • Factory Test: 100% inspection of resistance (200μΩ±3%), appearance and lead continuity; Factory Test Report issued.
  • Sampling Test: Per GB/T 2828.1-2012, sampling for withstand voltage, insulation and tensile strength, AQL=0.65.
  • Acceptance Documents: Factory test report, material certificate, RoHS/REACH compliance (upon request).
Packaging & Transportation
  • Packaging: Individually packed in anti-static bags, 50/100 pcs per box. Outer box labeled with model, quantity, date and batch number.
  • Transportation: Moisture-proof and anti-vibration packaging, avoid impact. Comply with RoHS and REACH for international logistics.
Core Functions
  • Flow Distribution / Collection: Distribute coolant from the main line evenly to multiple cold plates; collect heated fluid from each branch and return it to the cooling source / CDU after heat exchange.
  • Pressure & Resistance Management: Control pressure drop in each branch to prevent local overheating caused by uneven flow.
  • Simplified Piping & Maintenance: Reduce the number of connectors; with quick connectors, single cold plates can be rapidly installed or removed for maintenance.
  • Monitoring & Regulation (High-end Models): Integrated flow meters, temperature / pressure sensors, and even valves for fine-tuning flow in each branch.
Common Types & Structures
By Application
  • Manifold (Supply Side): 1 inlet, N outlets
  • Collector (Return Side): N inlets, 1 outlet; usually used in pairs
By Flow Division Method
  • Y-type / Tee Manifold: 1 inlet, 2 outlets; suitable for small systems with two cold plates
  • Bar / Row Manifold: 1 inlet, multiple outlets (e.g., 1-to-4, 1-to-6); commonly used in data centers / mining rigs
  • Annular Manifold: For closed-loop liquid cooling circuits
By Adjustability
  • Fixed Type: No valves, low cost; flow determined by orifice / channel design
  • Adjustable Type: Each branch equipped with needle / ball valves; flow adjustable manually or electrically
Material & Interface
Materials
  • Aluminum alloy: lightweight, moderate cost
  • Stainless steel: high pressure resistance, good corrosion resistance
  • Copper: excellent thermal conductivity but high cost
  • Must be compatible with system coolant to prevent corrosion
Interfaces
  • PC water cooling: commonly G1/4" thread
  • Industrial / data center: flanges, compression fittings, quick connectors (e.g., DME, ISO 8434)
Sealing
Must use O-rings / gaskets to prevent leakage; recommended materials: Nitrile Rubber (NBR) or Fluororubber (FKM)
Key Selection Parameters
  • Number of Branches & Flow Demand: Ensure sufficient flow for each cold plate to meet cooling requirements and avoid excessive pressure drop
  • Working Pressure / Temperature: Industrial cold plates typically operate at 0.3-1 MPa, 30-50°C
  • Flow Resistance & Uniformity: Flow channel design determines flow deviation; high-end systems require inter-branch flow deviation < 5%
  • Interface Size & Compatibility: Match inner diameter of tubing and connector type
  • Installation Space: Length and height of bar manifolds must fit cabinet / equipment layout
Application Scenarios
  • Personal PC / Workstation: Y-type manifold for CPU + GPU dual cold plates
  • Data Center AI Servers: Rack-mount bar manifolds, 1-to-8/16 for multi-GPU cold plates
  • Miner Clusters: Multi-branch manifolds cooling multiple hash boards simultaneously
  • New Energy Vehicle Battery Packs: Centralized supply and return for liquid cooling plates
Installation & Notes
  • Separate supply and return lines to avoid thermal short-circuit
  • Tighten connectors evenly; torque wrench recommended
  • Fully vent air during initial system filling
  • Regularly inspect seal aging to prevent leakage
  • Install manifold in an easily accessible and observable location
