Core Manufacturing Advantages

Advanced Brazing Technology: Utilizes vacuum brazing to ensure a seamless, high-strength bond between aluminum plates, maximizing thermal conductivity while eliminating leakage risks.
Optimized Fluid Dynamics: The internal flow channels are precision-engineered to reduce pressure drop and ensure uniform coolant distribution across the entire 288x125mm surface area.
Zero-Defect Quality Control: Every single cold plate undergoes rigorous in-process inspections, including 100% pressure and leak testing, to meet strict industrial and automotive safety standards.
Agile OEM Prototyping: We provide proactive Design for Manufacturability (DFM) support, enabling rapid transition from initial engineering validation to high-volume global production.

Frequently Asked Questions (FAQs)

Q1: What are the primary applications for this aluminum cold plate?

A1: This highly efficient heat sink is specifically designed for high-power thermal management, making it ideal for EV battery packs, AI and high-performance computing (HPC) servers, and heavy-duty industrial power electronics.

Q2: Can the dimensions and water tap sizes be customized?

A2: Yes. While the OC-M20S model measures 288x125x14mm with a 10mm OD tap, our engineering team provides full custom CNC machining and DFM analysis to modify dimensions, internal flow channels, and port placements to match your exact assembly requirements.

Q3: How do you guarantee the cold plate will not leak during operation?

A3: The structural integrity is secured through precision vacuum brazing. Additionally, 100% of our liquid cooling plates are subjected to strict pneumatic or hydrostatic pressure testing prior to shipment to guarantee zero-leakage performance.

Q4: What is the Minimum Order Quantity (MOQ) for custom thermal projects?

A4: We support agile R&D and pilot runs with a flexible MOQ starting around 5 to 10 pieces. Once the prototype is approved, our scalable manufacturing lines ensure stable and rapid high-volume OEM delivery.
