Liquid Cooling Cold Plate
liquid cold plate is a highly efficient thermal management component. It rapidly absorbs and transfers heat from electronic components via coolant circulating through internal sealed channels, enabling precise and efficient cooling of heat-generating components.
Indirect Liquid Cooling · Safe and Efficient
The coolant does not come into contact with the components; instead, heat exchange occurs via a highly thermally conductive metal plate, ensuring both performance and safety.
Technologically Mature · Widely Used
One of the most mature liquid cooling solutions available today, widely used in the new energy and industrial sectors.
Heat absorption
The liquid-cooled plate is tightly sealed against the heat source, allowing heat to be rapidly transferred to the surface of the metal substrate through thermal conduction.
Heat Transfer
The coolant inside the plate flows at high speed due to the pressure difference, rapidly absorbing and carrying away heat from the substrate.
Heat Dissipation
After absorbing heat, the hot fluid flows out of the cold plate and is transported through a closed-loop piping system to the outdoor heat dissipation unit.
Cooling Cycle
The hot fluid enters an outdoor heat exchanger (such as a cooling tower), where it releases heat by exchanging it with the ambient air and is cooled in the process.
A Continuous Cycle
The cooled low-temperature fluid is pumped back into the indoor liquid cooling plate by the circulation pump, beginning a new cycle of heat absorption and transport.
Extreme heat dissipation efficiency
Performance Comparison: A Quantum Leap
Liquids have a much higher specific heat capacity and thermal conductivity than air. Actual test data shows that liquid cooling solutions are three times more efficient than traditional air cooling, enabling rapid dissipation of heat generated by core components.
Addressing the Challenges of High Power Density
With the advancement of AI chips and HPC, power consumption per rack has surged from 2–3 kW to 8 kW or even 20 kW. Air cooling has reached its physical limits, while liquid cooling, with its superior heat transfer capabilities, has emerged as the only viable solution for this scenario.
