Roll Bonded Liquid Cold Plates for Demanding Thermal Applications
HeatsinkMaker delivers precision-engineered roll bonded liquid cold plates that combine high thermal performance with reliable, leak-free operation. Copper tubes are integrated into aluminum plates through a controlled roll-bonding process, creating efficient coolant channels without additional brazing or welding steps in many designs.

Key application sectors
Built for repeatable production
From prototype evaluation to high-volume OEM programs, each design is reviewed for thermal, mechanical, and manufacturing performance.
Thermal performance
Why roll bonded construction excels in high-power cooling
Roll bonded construction provides uniform heat spreading across large surface areas while maintaining low pressure drop. The embedded tube design eliminates thermal interface materials between the tube and plate, helping deliver consistent performance where air cooling reaches its limit.
Uniform heat spreading
Large surface areas can be cooled efficiently through integrated channel layouts.
Low pressure drop
Channel design is developed around flow requirements and application constraints.
Consistent contact
Embedded tubes avoid the need for an additional thermal interface between tube and plate.
Flexible geometries
Full-buried, half-buried, exposed, and sandwiched-tube configurations support different system needs.
Manufacturing capability
A complete cold plate production platform
HeatsinkMaker supports the full range of liquid cold plate technologies, from roll bonded and embedded-tube constructions to vacuum brazed and friction stir welded designs.
