Product Description
Our tube liquid cold plate adopts mature embedded copper tube forming technology, integrating seamless copper heat transfer tubes into precision milled aluminum base plates. This hybrid aluminum-copper structure balances lightweight rigidity and ultra-high heat conductivity, delivering reliable liquid cooling for high heat flux industrial, new energy and power electronic systems.
Unlike traditional friction stir welded cold plates, tube-in-plate liquid coolers feature flexible channel routing, lower production cost for medium-to-large batches, and exceptional pressure resistance for long-cycle liquid circulation cooling. Each cold plate undergoes full leak testing before shipment to eliminate fluid seepage risks under continuous operation.
Features
2.1 Premium Composite Thermal Structure
High-purity 3003/6061 aluminum substrate paired with oxygen-free copper tubes; copper’s thermal conductivity far surpasses aluminum, rapidly extracting concentrated heat loads while the aluminum plate provides flat mounting surface for heat sources like battery modules, IGBTs and server chips.
2.2 Custom Embedded Tube Layout Design
Engineers design copper tube pathways to match your heat distribution: serpentine, parallel, U-bend or multi-loop layouts available. Adjust tube diameter, wall thickness and channel spacing to optimize flow velocity, pressure drop and uniform temperature across the entire cold plate surface.
2.3 Robust Leak-Proof Sealing & Precision Fabrication
Tight CNC grooving + mechanical compression embedding process locks copper tubes firmly into aluminum slots; optional epoxy bonding or brazing reinforcement for extreme pressure working environments. 100% air pressure leak inspection (0.8MPa holding test) for every finished liquid cold plate.
2.4 Lightweight, Flat & Stable Mounting Base
Flatness controlled within ±0.05mm to ensure full contact adhesion with heating components, eliminating air gaps that degrade cooling efficiency. Aluminum base cuts total assembly weight vs full copper cold plates, ideal for mobile EV and portable energy storage equipment.
2.5 Wide Compatibility Coolant & Application Range
Works flawlessly with deionized water, glycol-water mixtures, dielectric cooling fluids; operating temperature spans -40°C to 120°C, supporting continuous 24/7 industrial duty cycles.
2.6 Full Customization Service
Custom dimensions, inlet/outlet copper pipe positions, thread fittings, mounting screw bosses, insulation coating and surface anodization (clear/black) per client drawings or thermal simulation data.

FAQ
Q1: What is a tube liquid cold plate used for?
A tube liquid cold plate is a passive liquid cooling component that uses embedded copper tubes to circulate coolant, drawing heat away from high-temperature components like lithium batteries, power inverters and semiconductors to maintain safe operating temperatures.
Q2: How does tube cold plate compare to friction stir welded cold plate?
Tube embedded cold plates have lower unit cost, faster prototyping and flexible channel design; FSW plates suit ultra-high pressure, ultra-thin plate scenarios. Our engineers recommend the best type based on your thermal load and budget.
Q3: Can you make custom size tube liquid cold plates for battery packs?
Yes. We fully customize length, width, plate thickness, tube path, fitting positions and mounting holes to match your battery module CAD drawings, and can provide thermal simulation reports pre-production.
Q4: Is the copper tube prone to detachment from the aluminum plate?
Our compression embedding process creates tight mechanical interference fit between copper tube and aluminum groove; for high-pressure use, brazing reinforcement eliminates any risk of tube separation during long-term operation.
