Water Cooled LED Heat Sink-FAQ's
What cooling performance can I expect?
Liquid cooling delivers significantly better heat removal compared to air-cooled sinks, ideal for high-power LEDs.
What materials are used?
We use aluminum alloys like 6061/6063 for the plate, with optional aluminum-copper hybrid solutions for enhanced conductivity.
Can channel layout be customized?
Yes-channel design, spacing, and flow patterns are tailored to meet your thermal flow requirements.
How are inlet and outlet ports managed?
Ports can be customized in size, location, and connector type according to your system needs.
How reliable is the sealing?
Plates are sealed using techniques like vacuum brazing and fully pressure-tested to ensure leak-free performance.
What surface finishes are available?
Options include mill finish, anodized protection, or custom coating for environmental resilience.
What thermal load range can be handled?
These cold plates support loads from under 100 W to multi-kilowatt LED systems.
Do you offer testing and validation?
Yes-every unit undergoes pressure and flow testing to verify thermal performance and water tightness.

Sinoextrud: Your Water Cooled LED Heat Sink Manufacturer
Water-cooled LED heat sinks utilize liquid as the primary heat-transfer medium, achieving superior thermal dissipation for high-power LED modules. Unlike traditional air-cooled solutions, these systems maintain lower junction temperatures and extend LED lifetime.
Manufactured using high-conductivity aluminum, the heatsink integrates precisely engineered internal channels and secure liquid sealing to ensure reliable, compact thermal solutions. Its slim, lightweight design facilitates integration into dense lighting systems.
Customization options-from channel design to surface finish-ensure compatibility with various fixture designs and environmental conditions. Leak-proof sealing and thorough testing reinforce the dependability of these cooling solutions.
Whether for compact LED strips or large luminaire arrays, these water-cooled heat sinks deliver scalable, high-efficiency thermal management-ideal for professional lighting, industrial installations, or high-flux architectural applications.
