Jamcor/SJS Products specializes in the design and manufacture of advanced thermal management solutions, including custom cold plates and liquid cooling solutions engineered to meet the demands of high-performance electronics and heat-intensive applications. Our team of experienced industry professionals can develop a tailored cooling solution that efficiently removes heat from critical internal components and ensures optimal performance, reliability, and long-term stability. With the tremendous power densities found in modern aerospace, semiconductor, and industrial systems, traditional air cooling systems are insufficient. Custom cold plates and liquid cooling solutions from Jamcor/SJS Products enable higher heat transfer rates, tighter thermal control, and improved system efficiency in compact environments.
Custom cold plates are liquid-cooled thermal devices engineered to extract dangerous heat directly from high-power components through internal fluid channels. These complex systems are designed to handle high heat flux densities that often exceed the limitations of traditional air-cooled heat sinks. Jamcor designs custom cold plates using a range of materials based on thermal requirements, such as aluminum (6061/6063), copper (C101/C110), stainless steel (304/316), and hybrid constructions such as aluminum bodies with copper inserts or baseplates. Using a combination of our in-house manufacturing services, we can develop custom cold plates that balance heat transfer coefficients, meet flow rate requirements, and constraints regarding pressure drops. Using Jamcor cold plates at the heat source minimizes thermal resistance and enables precise temperature control in advanced assemblies.
Beyond individual cold plates, Jamcor/SJS Products supports the development of complete liquid cooling solutions designed to regulate proper temperature levels across entire assemblies. These systems may include cold plates, pumps, flow control systems, heat exchangers, radiators, reservoirs, tubing, and quick-connect fittings. Using water-glycol mixtures, deionized water, or dielectric fluids, Jamcor liquid cooling systems are precision-engineered to manage heat loads, coolant flow rates, pressure drops, and a target temperature differential. When compared to air cooling methods, liquid cooling systems offer 3 to 10 times the heat transfer efficiency with a reduced reliance on heat sinks, resulting in more uniform temperature distribution and reliability during continuous operation.
Complex cooling solutions demand complex manufacturing processes, and Jamcor specializes in finding the optimal production methods that produce high-quality results in expedited production schedules and within budgets. Our early phase Design for Manufacturability services consider several factors like heat flux distribution, thermal interface resistance, material conductivity, and channel surface area before getting into the more technical fluid dynamics of liquid cooling. Those considerations include the benefits of laminar vs turbulent flow, channel geometries, flow uniformity across multi-component systems, and the logistics of cooling efficiency or pressure drop. Our team considers all factors from mounting interfaces to sealing methods and compatibility with surrounding components, providing a reliable and consistent level of service on complex projects.
Cold plates use liquid-based convective heat transfer, achieving a much higher heat transfer coefficient than using air-cooled heat sinks alone. This allows for more advanced electronic systems that produce higher heat flux, where cold plates can reduce hotspots and maintain tighter temperature control or lower ΔT.
Copper (C101/C110) offers maximum levels of thermal conductivity for high heat flux applications, while aluminum (6061/6063) provides a lighter, cost-effective alternative. Hybrid designs that combine multiple materials can maximize both heat spreading and overall system efficiency.
Channel geometry is critical to balance heat transfer and pressure drop. Serpentine paths improve coverage, parallel channels reduce restriction, and microchannels or pin-fin structures are used to increase surface area and turbulence for greater levels of thermal performance.
Critical factors to consider when starting development of a custom liquid cooling solution include heat load (W), target ΔT, coolant type, flow rate, and allowable pressure drop. Additional factors such as TIM selection, surface flatness, and system integration also impact performance and reliability.
Jamcor provides DFM guidance to optimize channel design, material selection, and manufacturing methods such as CNC machining, brazing, or FSW. Prototyping, leak testing, and pressure validation ensure performance before full production.
