Cold Plate Liquid Cooling
A liquid cold plate(LCP) is a key thermal management component designed to remove heat from high-power and high-heat-density equipment. Compared with traditional air cooling, liquid cold plates provide higher heat transfer efficiency and more stable temperature control.
During operation, heat is transferred from the heat source to the cold plate surface. Coolant flows through internal machined channels, embedded tubes, or sealed channel structures and carries the heat away through the cooling loop. With 15+ years of experience, we optimize water cooling plate designs to improve temperature uniformity, cooling efficiency, and long-term leak-free performance.
Liquid Cold Plates of Different Materials
Liquid cold plates are typically manufactured from copper, aluminum, or stainless steel. A copper cold plate offers the best thermal performance for high-power cooling, while an aluminum cold plate provides an excellent balance of weight, cost, and manufacturability. Stainless steel is mainly selected for applications requiring high corrosion resistance.

How Does a Liquid Cold Plate Work
A liquid cold plate transfers heat from electronic components to a circulating coolant through high-conductivity metal and internal flow channels. As the coolant flows through the sealed channels, it absorbs heat and carries it to an external heat exchanger, where the heat is dissipated before the cooled liquid recirculates. This closed-loop process provides efficient and stable thermal management for high-power electronic systems.
Cold Plates Liquid Cooling Solutions
At XY-GLOBAL, we provide various liquid cold plate solutions, including tube-embedded, brazed, friction stir welded (FSW), etc. Each solution can be customized based on your thermal performance, pressure drop, sealing, size, and installation requirements.
Embedded Tube Liquid Cold Plate
Grooves are machined into a metal plate, and copper or aluminum tubes are placed inside and fixed in position.
- Simple design, lower cost, and flexible production. Heat transfer is usually less efficient than a machined-channel cold plate.
Brazed Liquid Cold Plate
Cooling channels are formed in the base plate, and a cover plate is brazed onto it to create sealed channels.
- Flexible channel design, good cooling performance, compact structure, and suitable for mass production.
Friction Stir Welded (FSW) Liquid Cold Plate
Cooling channels are machined into an aluminum base plate, and the cover plate is sealed by friction stir welding.
- No filler material, strong welds, low deformation, and suitable for large or custom-shaped cold plates.
Spiral Channel Cold Plate
The spiral channel provides a larger cooling area and helps coolant flow around the heat source.
- Better temperature uniformity, fewer hot spots, and suitable for high-heat applications.
Applications of Liquid Cold Plates
A liquid cooling 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

Liquid Cold Plate FAQs
1. What is a liquid cold plate?
A liquid cold plate transfers heat from electronic components to a circulating coolant through internal cooling channels. It is commonly used for high-power equipment requiring efficient and stable cooling.
2. What are the advantages of liquid cooling compared with air cooling?
Liquid cooling transfers heat more efficiently than air cooling. It can handle higher heat loads, reduce hot spots, save installation space, and operate with less noise.
3. What coolants are commonly used in liquid cooling systems?
Common coolants include deionized water, water-glycol mixtures, dielectric fluids, and special cooling oils. The right coolant depends on temperature, corrosion resistance, electrical insulation, and system requirements.
4. What information is required for a liquid cold plate quotation?
Please provide your 2D or 3D drawings, material, dimensions, coolant type, flow rate, operating pressure, heat load, inlet and outlet positions, surface treatment, and required quantity.
5. What is the typical lead time for a custom liquid cold plate?
Lead time depends on the design complexity, material, welding process, testing requirements, and order quantity. Prototypes generally require less time than mass-production orders.
6. How do I choose the right liquid cold plate?
The right design depends on heat load, heat source location, coolant flow rate, pressure drop, operating pressure, available space, and installation method. Our engineers can review these requirements before production.
