Winshare Thermal provides superior brazed cold plates for your high heat flux applications
Frame 1321318651 (1)

Brazed Cold Plates

We join two or more metal plates (aluminum, copper, or stainless steel) by vacuum brazing. Inside, we build flow channels and dense fins. Coolant touches more surfaces. Heat moves out fast.
Core Features:
Vacuum join: Metal melts and seals tight. No leaks.
Microchannel dense fins: More contact with coolant.
Complex channels: Coolant swirls and grabs heat.
Full seal: Strong and leak-proof under pressure.
Thin but tough: High power in small space.

The main difference between brazed cold plates and embedded pipe cold plates

While both brazed cold plates and embedded tube cold plates are liquid cooling solutions, they differ significantly in their manufacturing processes, structural characteristics, and performance, making them suitable for different thermal management requirements:
Bonded-fin-heat-sink4_03
Manufacturing process
Brazed Cold Plates: Multiple metal sheets are fused together through high-temperature brazing (usually vacuum brazing) to form a single-piece internal flow channel and fin structure. This metallurgical bond provides excellent structural integrity.
Embedded tube cold plates: Cooling tubes (such as copper tubes) are typically pressed or bonded into pre-machined slots in the baseplate. A small gap may exist between the tubes and the baseplate, which typically needs to be filled with thermally conductive adhesive.
 
Internal structure and thermal resistance
Brazed cold plate: The internal structure can be designed with extremely complex and high-density fins or microchannels to maximize the contact area between the coolant and the cold plate material, thereby achieving extremely low thermal resistance and higher heat transfer efficiency.
Embedded pipe cold plate: The flow channel is usually a simple tubular structure. Heat needs to be transferred through the pipe wall and the contact surface between the pipe and the substrate, and the thermal resistance is relatively high.
Bonded-fin-heat-sink4_03
Sealing and reliability
Brazed Cold Plates: The metallurgical bond formed by brazing provides unmatched sealing, virtually eliminating the risk of leakage, suitable for critical applications and high-pressure environments where reliability is paramount.
Embedded tube cold plates: Although they can provide a reliable seal if designed properly, the risk of leakage is theoretically slightly higher than that of brazed cold plates due to the physical contact or gluing.
 
Applicable heat load
Brazed Cold Plates: Designed to handle extremely high heat flux and high power cooling needs.
Embedded Tube Cold Plates: Cost-effective for low to medium heat load applications.
