FAQ – High Efficiency Liquid Cold Plate

What is a liquid cold plate and how does it work?
A liquid cold plate is a heat exchanger that circulates coolant through internal channels to absorb and transfer heat away from high-power components. It provides more efficient heat dissipation than traditional air cooling, making it ideal for demanding thermal applications.

What are the benefits of FSW (Friction Stir Welding) cold plates?
FSW liquid cold plates offer leak-free, high-strength bonding with no internal porosity. This process ensures excellent thermal conductivity and mechanical stability, especially under high-pressure fluid conditions.

Can I customize the channel design and port locations?

Yes, we offer full customization services. You can specify channel layout, flow rate requirements, inlet/outlet port positions, and mounting hole patterns. Our engineering team can also assist with thermal simulations and design optimization.

What cooling fluids are compatible with your cold plates?
Our cold plates are compatible with a variety of coolants including water, deionized water, glycol mixtures (ethylene or propylene), and dielectric fluids. Material selection can be adjusted based on the fluid's chemical compatibility.

What industries commonly use high-performance liquid cold plates?
Common applications include electric vehicles (EV battery cooling), industrial laser systems, power inverters, telecom equipment, data center servers, and renewable energy systems such as wind and solar inverters.

What is the maximum operating pressure and temperature?
Typical operating pressure is up to 6 bar (customizable), and temperature tolerance ranges from -40°C to 120°C, depending on materials and fluid type.
