Liquid Cold Plate
A liquid cold plate is a key thermal management component used to remove heat from high-power and high-heat-density equipment. Compared with traditional air cooling, cold plate liquid cooling provides faster and more stable temperature control.
During operation, heat is transferred from the heat source to the cold plate surface. Coolant then flows through internal channels, embedded tubes, or welded passages inside the plate and carries the heat away through the cooling loop. A well-designed liquid cooling cold plate can help improve cooling efficiency, system stability, and long-term reliability.

Common Manufacturing Processes for Liquid Cold Plates

The manufacturing process for liquid cold plates should be selected based on the product structure, cooling power, flow channel design, sealing requirements, installation space, and cost target. We can provide customized liquid cold plate manufacturing solutions according to different project needs.
  • CNC machining for complex flow channels, mounting holes, sealing grooves, flat contact surfaces, and precision structures.
  • Aluminum extrusion for cooling profiles, basic channels, and cost-effective batch production.
  • Stamping for thin plate parts, cover plates, flow guide plates, brackets, and simple channel structures.
  • Friction stir welding for sealing aluminum liquid cold plate channels with high strength and reliable sealing performance.
  • Laser welding for precision joining and complex structural requirements.

Applications of Liquid Cold Plates

A liquid cooled cold plate is suitable for high-power equipment where traditional air cooling is not enough. Common applications include:

  • New energy vehicle battery packs, electric control systems, inverters, and charging modules
  • Energy storage systems, power supplies, and power modules
  • Servers, data centers, AI servers, and high-performance computing equipment
  • Laser equipment, fiber lasers, and optical devices
  • Medical equipment, inspection instruments, and laboratory equipment
  • Industrial automation equipment, servo drives, and control modules
  • Semiconductor equipment, communication equipment, and high-power electronic components

Why Choose XY-GLOBAL?

For a reliable liquid cooled cold plate, cooling performance is only one part of the requirement. Surface flatness, sealing reliability, welding quality, internal cleanliness, and dimensional accuracy are also important.
At the project evaluation stage, we review the heat source position, cooling power, installation space, port locations, load-bearing requirements, and drawing structure. We can also support CFD or thermal simulation when needed to help optimize cooling performance, manufacturability, sealing reliability, and cost.
For manufacturing, we are equipped with multiple CNC machines, including 5-axis CNC equipment. Our CNC machining accuracy can reach 0.005 mm, making us suitable for high-precision liquid cold plates and complex cooling components.
For surface quality, we provide anodizing, powder coating, and other surface finishing options according to customer needs. We also pay attention to deburring, cleanliness, and port smoothness to keep internal channels, drainage holes, and connection ports free from obvious burrs, aluminum chips, blockage, or residue.
For inspection and testing, we use 2.5D and CMM inspection equipment to check key dimensions, hole positions, flatness, and assembly requirements. CMM inspection accuracy can reach 0.001 mm. We can also perform air tightness testing, nitrogen high-pressure leak testing, pressure holding tests, and other leak testing solutions according to project requirements.
