Liquid Cooled Plate Heat Sink-FAQ's

What is a liquid-cooled plate heat sink?
It’s an aluminum heat sink with integrated internal cooling channels, designed for efficient liquid circulation to remove heat.
Why use aluminum instead of copper?
Aluminum offers good thermal performance, lower weight, and cost efficiency while remaining easy to process.
Can flow paths and ports be customized?
Yes-coolant channel layout, inlet/outlet size, and position are fully adjustable to meet system design needs.
Are these suitable for continuous operation?
Absolutely-liquid-cooled plates maintain consistent performance even under sustained high thermal loads.
Do you provide surface treatment?
Yes, we offer anodizing, powder coating, and other finishes based on corrosion or appearance requirements.
What industries typically use these heat sinks?
Commonly used in LED lighting, telecom, industrial power, automotive, and data center applications.
Do you support both small batch and mass production?
Yes-we support prototyping, pre-series testing, and high-volume runs with consistent quality control.
