Vacuum Brazed Microchannel Cold Plate | Custom Liquid Cooling Heatsink - BY Thermal
What is the typical lead time for custom microchannel cold plates?
Standard prototypes typically ship in 2-3 weeks. Production quantities range from 4-6 weeks depending on complexity and volume. Rush services are available for urgent projects.
Can you provide thermal simulation and design support?
Yes, our engineering team offers CFD thermal simulation services to optimize your cold plate design. We can analyze flow distribution, pressure drop, and thermal performance before manufacturing.
What materials do you use for vacuum brazed cold plates?
We primarily use C1100/C1020 copper for maximum thermal conductivity and AL6061/3003 aluminum for weight-sensitive applications. Other materials like stainless steel are available for special requirements.
What is the minimum order quantity (MOQ)?
We have no mandatory MOQ. However, higher order quantities will bring down the unit cost accordingly.
Do you offer custom surface treatments and coatings?
Yes, available finishes include electroless nickel plating (for corrosion resistance), chromate conversion coating, hard anodizing (aluminum), and various passivation treatments.

Production Information
BY Thermal specializes in manufacturing high-performance vacuum brazed microchannel cold plates for high-heat-flux applications up to 500W/cm². Our precision-engineered liquid cooling heatsinks deliver superior thermal performance for IGBT modules, data center servers, EV battery packs, and laser systems. With advanced vacuum brazing technology and fully customizable designs, we provide reliable thermal solutions tailored to your specific requirements.
What is a Vacuum Brazed Microchannel Cold Plate?
A vacuum brazed microchannel cold plate is an advanced liquid cooling component that uses precision-machined microchannels (typically 0.08-0.3mm hydraulic diameter) to maximize heat transfer surface area. The vacuum brazing process creates a metallurgical bond between the channel structure and the cover plate, ensuring leak-free operation with minimal thermal resistance.
Unlike traditional tube-and-plate or extrusion cold plates, our vacuum brazed microchannel design offers:
– **Higher heat flux capacity**
– **Lower thermal resistance**
– **Uniform temperature distribution**
– **Compact form factor**
– **High pressure tolerance**
Our microchannel cold plates are manufactured using high-purity copper (C1100, C1020) or aluminum alloys (AL6061/3003), selected based on your application requirements for thermal conductivity, weight, and corrosion resistance.
