Why Choose Copper/SUS Tube Liquid Cold Plates

As electronic systems reach unprecedented power densities, traditional air cooling often falls short. Copper and Stainless Steel (SUS) tube liquid cold plates provide an exceptionally reliable cooling solution. Copper offers superior thermal conductivity for rapid heat absorption, while SUS tubes ensure outstanding corrosion resistance against specialized coolants or harsh operating environments. This structural design maximizes heat transfer away from high-power components, making it the industry standard for extreme thermal management.

Our End-to-End Tube Liquid Cold Plate Manufacturing Process

As a fully integrated thermal solutions manufacturer, KingKa controls every step of the production cycle in-house. From raw material inspection to final flow testing, our comprehensive manufacturing process ensures that every custom copper and SUS tube cold plate meets strict ISO 9001:2015 and IATF 16949 standards, delivering uncompromising performance for your high-power systems.

Premium Material Sourcing & Strict IQC

The foundation of a high-performance cold plate is its raw material. Our SQE (Supplier Quality Engineering) and IQC teams strictly evaluate and inspect all incoming metals. We utilize high-grade aluminum alloys (such as AL6061 or AL7075) for the base plates to ensure structural integrity, and high-purity copper or stainless steel (SUS) for the cooling tubes to guarantee optimal thermal conductivity and fluid compatibility.

High-Precision CNC Channel Routing

Unlike standard machining, liquid tube routing requires extreme precision to avoid thermal bottlenecks. Utilizing our fleet of 3, 4, and 5-axis CNC machining centers, we mill complex, high-density channel layouts into the aluminum base. We maintain ultra-tight machining tolerances to ensure a perfect mechanical fit for the cooling tubes, which is critical for maximizing heat transfer.

Custom Tube Bending & Proprietary Hi-Contact Pressing

The copper or SUS tubes are custom-bent to match the specific channel architecture. Using KingKa’s proprietary Hi-Contact manufacturing technique, the tubes are forcefully embedded into the base plate. This specialized pressing process significantly increases the tube-to-plate contact area, reducing interface thermal resistance and ensuring the tubes are securely locked in place.

Thermal Epoxy Application & Surface Machining

To eliminate microscopic air gaps that act as thermal insulators, a specialized thermal epoxy is precisely applied at the tube-to-plate joints. Once cured, the entire cold plate undergoes high-precision fly-cutting and surface grinding. This critical step ensures a perfectly flat and smooth contact surface, allowing your high-power electronic components to mount seamlessly for maximum heat absorption.

Rigorous Fluid Validation & Leakage Testing

Liquid cooling systems demand zero margin for error. Before moving to final finishing, every cold plate is sent to our in-house test lab. We conduct 100% airtightness leakage detection and utilize a two-stage flow resistance testing machine. This guarantees that the internal channels are clear of debris and the assembly can withstand high fluid pressure without leaking.

Final FQC/OQC & Dimensional Inspection

In the final stage, our quality control team performs comprehensive 100% sorting (FQC) and pre-delivery inspections (OQC). We utilize advanced HEXAGON Coordinate Measuring Machines (CMM) and 2.5D optical projectors to verify all geometric dimensions and tolerances. Only parts that perfectly match your CAD drawings are securely packaged for global delivery.

Copper、SUS Tube Liquid Cold Plate FAQ

Q What makes KingKa's Copper/SUS Tube Liquid Cold Plates superior to traditional finned heat sinks?

A Traditional air-cooled heat sinks reach thermal limits in high-power density applications. KingKa’s Tube Liquid Cold Plates utilize a proprietary Hi-Contact™ manufacturing process. By embedding highly conductive Copper (1100) or Stainless Steel (SUS) tubes directly into precision-extruded or CNC-machined aluminum base plates, we maximize the tube-to-device contact area. Combined with specialized thermal epoxy, this yields a gap-free thermal interface, dramatically reducing thermal resistance and efficiently managing extreme heat loads in highly compact footprints.
Q How does KingKa guarantee zero-leakage reliability for mission-critical liquid cooling systems?

A Coolant leakage is catastrophic in electronics. We eliminate this risk through our ISO 9001 and IATF 16949 certified quality protocols. Depending on the design architecture, we employ advanced vacuum brazing, Friction Stir Welding (FSW), or precision soldering to create hermetically sealed joints. Furthermore, every unit must pass through our in-house testing laboratory, undergoing 100% airtightness leak detection, dynamic flow resistance measurement, and hydrostatic testing before dispatch, ensuring absolute reliability for automotive and data center deployments.
Q Do you provide custom tube routing and manifold designs for complex system architectures?

A Absolutely. We offer comprehensive thermal engineering services, not just build-to-print manufacturing. Our R&D engineers utilize advanced 3D Pro/E modeling and CFD (Computational Fluid Dynamics) thermal simulations to optimize tube routing, pitch, and diameter based on your specific heat dissipation parameters and spatial constraints. We routinely engineer bespoke cooling modules for sophisticated sectors, including EV powertrains, High-Performance Computing (HPC) servers, and semiconductor testing equipment.
Q Which industrial coolants are compatible with your Copper and Stainless Steel (SUS) tubing?

A Material selection is dictated by your specific fluid chemistry. Our Copper (1100) tubes provide peak thermal conductivity, ideal for treated water or Ethylene Glycol/Water (EGW) mixtures. For aggressive coolants, Deionized (DI) water, or dielectric fluids where galvanic corrosion is a concern, we strategically integrate Stainless Steel (SUS 304/316) tubes. This tailored material integration ensures long-term internal corrosion resistance and extends the operational lifespan of your entire liquid cooling loop.
Q What is your production capacity and expected lead time for custom prototypes and mass manufacturing?

A Backed by 16+ years of specialized thermal manufacturing, KingKa operates a modernized facility equipped with 50+ high-precision CNC machining centers, dedicated skiving machines, and FSW lines, yielding an annual capacity exceeding 60,000 units. We offer rapid prototyping with initial DFM (Design for Manufacturability) analysis delivered within 24 hours of CAD submission. Our highly optimized supply chain ensures deeply compressed prototype lead times and a seamless, on-time transition to high-volume mass production.
