Dongguan Pioneer Thermal Technology Co., Ltd. is one of the leading manufacturers and suppliers of copper tube cold plate in China. Please feel free to buy customized copper tube cold plate made in China here from our factory. Welcome to contact us for quotation and free sample.
Product Description
Copper tube cold plate embeds seamless copper tubes into aluminum substrate via pressing or casting. Coolant flows inside copper pipes to take away concentrated heat efficiently owing to copper's superior thermal conductivity. CNC drilling is available for customized mounting holes after molding. With reliable leakproof performance and low production cost, it is commonly applied in new energy batteries, automotive ADAS modules and high-power industrial inverters.
Product Features
Press-Fit Embedded Copper Tube Structure
Seamless copper tubes fully pressed and locked inside the aluminum substrate, tight contact eliminates air gaps to minimize thermal resistance between tube and base.
01
Dual-Material High Heat Transfer Design
Aluminum base provides large flat contact surface for heat sources; copper tubing offers outstanding thermal conductivity for fast liquid heat exchange.
02
Custom Post CNC Machining Support
After cold plate forming, we complete drilling, tapping, counterbores, positioning brackets and edge profile processing to match customer PCB and module mounting layouts.
03
Fully Sealed Leak-Proof Construction
Precision tube embedding process avoids coolant leakage; every finished unit undergoes air pressure leak testing before delivery for long-term stable operation.
04
Uniform Flat Heat Contact Surface
Flat milled top plate ensures full close contact with batteries, power chips and inverter modules, preventing local hotspots across the whole cooling area.

Advantages
Lower Production Cost
Press-fit embedding process cuts complex welding/brazing procedures, reducing overall manufacturing lead time and cost for mass orders.
Ultra-Low Thermal Interface Resistance
Tight mechanical compression between copper tube and aluminum base maximizes heat transfer efficiency, outperforming loose cast-in tube cold plates.
Excellent Long-Term Leakage Resistance
No welding seams along the cooling loop, eliminating hidden leakage risks common in welded liquid cold plates under continuous thermal cycling.
Flexible Full Customization
Adjust tube flow paths, mounting hole positions and external connectors freely via in-house CNC machining without outsourcing secondary processing.
Lightweight & High Structural Rigidity
Solid aluminum base plate is lighter than full copper cold plates while maintaining enough rigidity for battery pack and inverter heavy load installation.
Wide Compatibility With Coolants
Copper tube design supports water, glycol mixed coolant and low-viscosity industrial cooling fluids without corrosion risk.
