Features of Liquid Cold Plate

High Thermal Conductivity Materials
The Liquid Cold Plate utilizes aluminum alloy or copper materials to rapidly transfer heat through their superior thermal conductivity, making it suitable for dissipating heat from sources generating 200W or more.

Structural Stability
Featuring a monolithic structure formed via welding or brazing, the internal flow channels are integrally molded. Capable of withstanding pressures exceeding 1 bar, the unit resists deformation or cracking even under prolonged thermal cycling conditions.

Surface Protection Treatment
The surface can undergo chromating or plating treatments to enhance oxidation and corrosion resistance, ensuring stable operation for 5 to 8 years in standard coolant environments.

FAQ

Q: What is the fundamental principle behind a Liquid Cold Plate?

A: A Liquid Cold Plate circulates a coolant through internal channels to transfer and carry away the heat generated by a heat source, thereby achieving continuous cooling.

Q: In which types of equipment are they primarily used?

A: They are commonly utilized in thermal management applications for servers, power modules, battery systems, and high-power electronic components.

Q: How does it achieve heat dissipation?

A: It relies on a combination of metal thermal conduction and liquid convection to transfer heat from the heat source to the coolant, which then carries it out of the system.

Q: Is it susceptible to corrosion?

A: Through surface treatments such as chromating or plating, Liquid Cold Plates maintain excellent corrosion resistance within a coolant environment.

Q: What is the installation method?

A: They are typically secured to the surface of the heat source using bolts or clamping plates to ensure intimate contact for effective heat dissipation.

Q: How is maintenance performed?

A: Regular inspections of the coolant's condition and the integrity of interface connections are required; additionally, the system must be kept clean to ensure stable operation.
