The embedded water cooling plate is an advanced thermal management solution engineered for high-performance electronic systems. By incorporating internal microchannels or machined flow paths directly into the base plate, this system enables efficient liquid circulation and localized cooling at critical heat-generating components.
■ Internal Channel Integration
Coolant channels are embedded within the metal substrate—typically aluminum or copper—through CNC machining or brazing techniques. This design minimizes thermal resistance and maximizes heat exchange surface area.
■ Superior Thermal Conductivity
With the use of high-purity metals and optimized flow designs, the cooling plate achieves excellent heat transfer coefficients (typically > 5000 W/m²K), ensuring rapid heat dissipation from power devices, semiconductors, or laser modules.
■ Uniform Temperature Distribution
Customizable flow path geometry and inlet/outlet positioning allow for precise thermal control and uniform temperature management, reducing thermal stress across sensitive components.
■ Scalable for Power Density
Supports power densities exceeding 100 W/cm², making it suitable for modern high-density electronics such as IGBTs, SiC modules, EV battery packs, and high-frequency RF boards.
■ Compatibility & Customization
Available in multiple materials (Al, Cu, Cu-Al hybrid) and compatible with various coolants (water, glycol mixtures, dielectric fluids). Plates can be customized in thickness, surface finish, mounting holes, and connection ports.
Yes, send us the drawing and surface treatment requirements, our engineer will evaluate your drawing and give you a quotation.
Yes, we will not release your design to third party unless with your permission. And we can sign the NDA before you send the drawing.
We will charge the tooling cost, but the tooling cost can be refunded when mass production.
MOQ will be set according to your product and drawing requirements, but generally we will not set MOQ.
We can provide sample production, and the mass production will be carried out after the sample is confirmed to you.
Please rest assured that all our products are QC inspected and accepted with inspection report before delivery and generally there will no non-conformance; in case of non- conformance, please contact us immediately, take some pictures, we will check on the problems and have them reworked or repaired at the first time , the resulting transportation costs borne by our company.
