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
Install manifold in an easily accessible and observable location
