Embedded copper-tube liquid cold plate adopts 6061/3003 aluminum alloy substrate with CNC grooving. A bent integral TP2 oxygen-free copper tube is embedded into the aluminum groove. By vacuum brazing or interference press-fitting process, the copper tube is tightly bonded with the aluminum base to form an integrated component. Coolant circulates inside the continuous copper tube to rapidly remove concentrated heat from high-power components such as IGBTs, on-board ECUs and energy storage PCS converters. It is a mainstream liquid cooling component for new-energy power electronic equipment.

 

The continuous one-piece copper tube flow channel has no internal splicing welds, greatly reducing leakage risks and offering outstanding pressure resistance. It is ideal for high-reliability cooling applications including high-voltage high-power vehicle-mounted ECUs and inverters.

 

 

✅ Continuous Copper Tube Circuit, Ultra-Low Leakage Risk Fabricated from a single seamless oxygen-free copper tube through bending, with no intermediate welding joints; joints are only arranged at the inlet and outlet ports. Every unit undergoes hydrostatic and air tightness leakage test before delivery, delivering stable performance under long-term vehicle vibration and high-low temperature cycling conditions.

 

✅ Copper-Aluminum Composite Structure for High Heat Flux Heat Dissipation Oxygen-free copper boasts excellent thermal conductivity to quickly absorb heat from local hotspots. The aluminum alloy substrate provides flat mounting surface and structural support, balancing heat dissipation performance and lightweight design to resolve local overheating issues of high-power devices.

 

✅ Fully Customizable Flow Channel with Thermal Simulation Serpentine, U-shaped and special-shaped multi-path flow channels can be designed on demand. The copper tube routing can be planned according to heat source positions. Substrate outline, mounting counterbores, positioning holes and inlet/outlet connector positions are all non-standard customizable to fit limited equipment space.

 

✅ High Pressure Resistance for High-Voltage Working Conditions Oxygen-free copper tube features high mechanical strength. Normal working pressure reaches 1.0 MPa, and reinforced version supports up to 1.6 MPa, much higher than conventional cavity-type cold plates. Suitable for high-voltage ECU and energy storage converter applications.

 

✅ Automotive-Grade Quality Control, IATF16949 Production Standard Full-process machining and inspection with strict control of plate flatness. Anodizing, anti-corrosion and insulating coating are available. Prototype sampling, small-batch trial and mass volume production are supported.

 

✅ Controllable Lead Time Compared with cavity brazed cold plates, tube embedding process features shorter production cycle, suitable for rapid project verification.
