Vacuum Brazed Aluminum Liquid Cold Plate for EV Battery & Power Electronics Thermal Management

Introduction：
Manufactured with full vacuum brazing technology, our liquid cold plate delivers premium thermal management for high-power applications—from EV battery packs and IGBT modules to energy storage systems, servers, and charging piles.
● Superior Heat Dissipation: High thermal conductivity quickly dissipates heat to stabilize device temperature under heavy continuous loads.
● Zero-Leakage Durability: Vacuum brazing forms integrated metallurgical bonding, resisting high pressure, thermal cycles and mechanical stress.
● Full Customization & Precise Fabrication: Customize outlines, channels and pipe ports; CNC precision machining guarantees stable cooling efficiency.
● Space-Saving & Flexible Material Options: Compact optimized flow paths cut volume; aluminum/copper hybrid materials are optional for different cooling demands.

Product Description


Custom Vacuum Brazed Liquid Cold Plate – Seamless Aluminum Water Cooling Solution for High Heat Load Electronics
Our vacuum brazed liquid cold plate is manufactured with full vacuum brazing technology, a premium liquid cooling thermal solution designed for high-power heat dissipation scenarios including electric vehicle battery packs, energy storage converters, IGBT power modules, server CPUs, and new energy charging piles.
Unlike traditional friction stir welded or stamped cold plates with hidden leakage risks, our vacuum brazed liquid cold plate forms fully seamless integrated cooling channels under high-temperature vacuum environment, eliminating micro gaps and fluid leakage failure fundamentally. We support one-stop custom service for size, channel layout, inlet/outlet pipe position, mounting hole layout to match your exclusive thermal system requirements.
 

Industrial Liquid Cold Plate Solution


Project Background
A leading manufacturer of industrial control equipment faced risks of frequency reduction and system crash, as the core temperature of its new high-power CPU module neared the limit during long-term full-load operation. The client required a customized liquid cooling solution with three key demands. Firstly, it needed efficient heat dissipation to keep core temperature within specification and support 7×24-hour continuous operation. Secondly, the structure had to be fully compatible with the existing mounting holes and internal space without any equipment modification. Thirdly, it must deliver long-term stability, adapt to industrial pure water circulation, feature excellent corrosion resistance and prevent liquid leakage.
Customized Solution
Based on on-site working conditions and technical requirements, we developed a high-precision all-aluminum liquid cold plate. The product is integrally milled from a solid aluminum ingot via CNC machining. Its internal flow channel is optimized through fluid dynamics simulation to ensure even water flow without dead zones, greatly improving heat exchange efficiency. Mounting holes and positioning structures are precisely designed according to client drawings for zero-tolerance fitting and direct installation. The whole plate adopts environmental passivation treatment to form a dense protective film on the aluminum surface, enhancing corrosion resistance and adapting to long-term circulating liquid cooling conditions.
Project Results
After delivery, the product passed multiple rigorous tests. The temperature of core components remained within standard under full load, completely eliminating overheating risks. The cold plate is easy to install with no secondary processing required and fits existing equipment perfectly. No leakage or performance degradation occurred during long-term aging tests. At present, this cooling solution has become a standard supporting part for the client. We have completed stable bulk deliveries with zero heat-dissipation-related failures, providing solid support for the long-term safe operation of equipment.

FAQ


Q1: What is the difference between vacuum brazed cold plate and friction stir welded cold plate?
A: Vacuum brazed liquid cold plate forms an integral seamless channel inside two aluminum sheets via high-temperature vacuum brazing, with lower thermal resistance and zero leakage risk. Friction stir welding only seals plate edges, internal channels still have separation risks under high coolant pressure.

Q2: Can I customize the channel shape and inlet pipe position?
A: Yes. We fully customize serpentine flow paths, pipe angle, pipe length, mounting hole positions based on your equipment installation drawings. We can produce vacuum brazed cold plates matching your mechanical outline like the irregular L-shaped sample shown.

Q3: What coolant can circulate inside the vacuum brazed liquid cold plate?
A: Compatible with deionized water, water-glycol mixed coolant, industrial low-temperature heat transfer fluid, not suitable for strong acid corrosive liquid.
