What Is a copper tube liquid cold plate?
A copper tube liquid cold plate is a cooling solution used in electronic devices to prevent them from overheating. It is a passive cooling system that transfers heat from electronic components to a liquid coolant circulating through copper tubes embedded in a flat plate. The cooled liquid then carries away the heat generated, dissipating it into the air or through a liquid-to-air heat exchanger.
How Does a Copper Tube Liquid Cold Plate Work?
The copper tube liquid cold plate works on the principle of heat transfer. When electronic components generate heat, it is absorbed by the copper tubes. As the coolant circulates through the tubes, it picks up the heat and carries it away from the components. The liquid coolant then releases the heat through natural convection or a heat exchanger. The large surface area of the cold plate enables efficient heat dissipation, making it an effective cooling solution for high-performance electronic devices.
