Multiple Profile Aluminum Cold Plate With Copper Pipe

1. Product Overview

This is a composite liquid cooling heat dissipation component with an aluminum alloy body and embedded TP2 copper cooling tubes. It combines the merits of aluminum alloy — easy machining, light weight and low cost — and red copper — high thermal conductivity, great pressure resistance and corrosion resistance. It is a widely adopted cooling solution for power electronics and industrial control equipment.

2. Structural Features

The main body is made of extruded aluminum profiles or milled aluminum plates. Mounting surfaces, fixing holes and special shapes can be processed as required to fit various equipment.

The cooling circuit adopts seamless red copper tubes, which support flexible layout including single circuit, multi-circuit and bent flow channels.

The aluminum base is closely attached to copper tubes to minimize contact thermal resistance, enabling rapid heat transfer from the aluminum plate to the coolant.

3. Core Advantages

✅ Excellent Thermal Conductivity: Red copper features much higher thermal conductivity than aluminum, delivering outstanding heat exchange efficiency for medium and high-power heat-generating components.

✅ Reliable Pressure Resistance & Leak Tightness: Seamless copper tubes boast strong pressure resistance and deformation resistance with zero leakage under normal liquid cooling system pressure.

✅ High Cost Performance: Aluminum body controls overall cost and weight, while copper tubes at key heat exchange areas ensure superior cooling performance.

✅ Flexible Machinability: The aluminum body can be fabricated into complex shapes, and copper tubes can be bent freely, perfectly suitable for non-standard equipment.

✅ Wide Compatibility: Copper tubes resist corrosion from coolants, and can work stably with ethylene glycol aqueous solution, pure water and other media for a long time.

4. Common Material Matching

Aluminum Base: 6061 / 6063 industrial aluminum profiles & plates (balanced mechanical strength and machinability)
Cooling Tube: TP2 red copper tube (universal industrial pure copper with good thermal conductivity, ductility and sealing performance)

5. Core Technical Parameters

Normal working pressure: 0.8–1.2 MPa
Pressure holding test: 1.0 MPa, no leakage after 30 minutes
Operating temperature: -40℃ ~ +85℃
Applicable coolants: Ethylene glycol aqueous solution, industrial pure water, dedicated antifreeze

6. Main Application Scenarios

Photovoltaic inverters, energy storage inverters, industrial frequency converters

High-power power supplies, rectifiers, charging pile power units

Rail transit electronic control equipment, industrial servo systems

7. Main Manufacturing Process

Aluminum profile/plate cutting → Tube bending & forming → Copper tube embedding → Compression / glue filling / tube expansion fastening (to reduce contact thermal resistance) → Joint welding → Hydraulic & air tightness test → Precision shaping → Surface treatment → Final inspection

8. Selection Comparison (vs FSW / Brazed Integrated Cold Plates)

Advantages: Fast design modification, lower cost for small-batch and non-standard products, and convenient maintenance & replacement of copper tubes.

Disadvantages: Overall flatness is slightly inferior to fully welded cold plates; not applicable to extreme vibration and ultra-high pressure working conditions.

Selection Suggestion: Prioritize this product for medium & low-power equipment, customized projects and cost-sensitive applications. Multiple Profile Aluminum Cold Plate With Copper Pipe Liquid Cold Plate
