Eaton liquid cold plates are precision heat exchanging components that mount directly onto heat-generating devices, including CPUs, GPUs, power electronics, PCBAs, and EV battery cells, and transfer waste heat into a circulating coolant.
Eaton liquid cold plates act as the part of a liquid cooling system that absorbs waste heat from devices like semiconductors, microprocessors, printed circuit board assemblies (PCBAs) or other power electronics and transfers it to the liquid cooling system. Optimize cooling efficiency and uphold the ideal operating temperature of electronic components by harnessing the exceptional heat-absorbing capabilities of liquid through cold plates.
Leverage the high heat capacity of liquid to quickly absorb more heat than air cooled thermal management solutions. Coldplates excel at dissipating high-density, high-output heat loads within a diverse range of system configurations, facilitating the effective transfer of heat into the liquid cooling system.
Cold plate cooling works by placing a thermally conductive plate directly against a heat-generating component. Coolant, typically deionized water or a water-glycol mix, is pumped through internal channels or passages within the plate. As the coolant flows through, it absorbs heat conducted from the device through the plate material. The heated coolant then travels through a liquid loop to a heat exchanger or coolant distribution unit (CDU), where the heat is rejected before the cooled fluid is recirculated. The internal flow path geometry is engineered to balance heat transfer efficiency against acceptable pressure drop for the system.
Backed by 40+ years of cold plate engineering and manufacturing expertise, Boyd Thermal by Eaton’s engineers excel at developing and manufacturing high quality, compact and durable coldplates. Thermal simulation and CFD modeling are available from the design stage to meet your system requirements while reducing weight and complexity.

Stamped cold plates are a lightweight cold plate construction that leverages the manufacturing efficiency of aluminum stamping one or both sides of the LCP. This approach further reduces manufacturing time and costs by streamlining flow path, mounting geometry and other features into a single process and eliminates CNC time. Stamped cold plates can be enhanced with internal fins to boost thermal efficiency and are controlled atmosphere brazed (CAB) brazed for 100% leak-tested seals.
Stamped cold plates are typically constructed entirely from aluminum, simplifying material compatibility across the cooling loop and reducing galvanic corrosion risk.
Machined and brazed cold plates offer the most flow path and structural geometry customization for a heat source to liquid system interface. Optimize complex, 100% leak-tested flow channels with precision CNC machining and high-quality CAB or vacuum brazing. Boyd Thermal by Eaton’s broad technology portfolio enables additional performance boost with fin inserts to further enhance heat transfer into the liquid system.
Eaton round tube liquid cold plates are cost-effective component cooling for low to moderate heat loads. Tubed cold plates consist of copper or stainless-steel tubes pressed into channeled aluminum plates using either our Hi-Contact™ or Press-Lock technologies. Tube cooling plates are available with either continuous tube styles or a manifold style. Enhance tube cold plate performance with the addition of turbulators by 5-15%.
Flat tube cold plates are ideal to cool small, high heat density components like thermoelectric coolers in limited vertical spaces. Using thin-walled aluminum multi-port extrusion (MPE) tubing, flat tube cooling plates minimize thermal resistance between the cold plate and heat source and produce surface thermal uniformity. Flat tube LCPs use more viscous fluids like ethylene glycol and water (EGW), oils, 3M Fluorinert and Polyalphaolefin (PAO) with their enhanced internal surface area and low pressure drop.
Wetted path needs to be compatible with other components in the liquid loop. Mixing copper and aluminum leads to galvanic corrosion that decreases system performance and lifetime.
