KINGKA manufactures custom Liquid Cold Plates for applications that require efficient heat removal within a defined mechanical envelope. Our cooling solutions include friction stir welded, embedded tube and brazed cold plates, with CNC machining supporting customized channels, mounting features and coolant connections.
Whether your project involves power electronics, battery modules or industrial equipment, cold plate selection begins with the operating conditions: heat load, coolant, available flow, pressure-drop limit and installation space.
A liquid cold plate is a metal heat exchanger that transfers heat from a component into circulating coolant. It typically incorporates a component mounting surface, internal coolant passages, and inlet and outlet connections.
Heat passes through the contact interface into the plate. Coolant absorbs that heat as it travels through the internal passages, then carries it to a separate heat exchanger for rejection.
The cold plate therefore connects the heat-generating device to the wider liquid cooling system.
Liquid cooling is worth evaluating when airflow, available space or temperature limits make a conventional heat sink difficult to implement.
A cold plate collects heat close to the device and allows the system to reject it elsewhere. This can reduce the space required for fins around the component and support cooling of concentrated or distributed heat sources.
However, the complete system still requires appropriate plumbing, pumping, heat rejection and leakage management. Selection should consider total system requirements rather than cold plate size alone.
The manufacturing process influences channel geometry, coolant contact materials and production cost. KINGKA offers several construction options to accommodate different requirements.
| Construction | Main Design Opportunity | Important Selection Consideration |
|---|---|---|
| FSW cold plate | Custom machined channels sealed with a welded cover | Channel layout and weld accessibility |
| Embedded tube cold plate | Formed tubing integrated into a metal base | Tube routing and tube-to-plate thermal contact |
| Brazed cold plate | Assembly of internal cooling features and external components | Joint quality and internal flow resistance |
Friction stir welding joins a cover to a machined base using a rotating tool. The process allows cooling passages to be positioned around the component layout.
An FSW design can be evaluated when a project needs customized channels, mounting geometry and coolant connections within an aluminum assembly.
A tube cold plate incorporates formed tubing into a machined metal base. The tube carries coolant beneath the heat-generating components, while the base provides the mounting and heat-spreading surface.
Effective construction depends on the thermal contact between tube and plate. Tube diameter, bend geometry and routing also influence cooling coverage and hydraulic resistance.
Brazed construction joins separately manufactured components into a cooling assembly. Internal fins or other heat-transfer features can be incorporated where the design requires additional coolant contact area.
The resulting thermal benefit must be evaluated alongside pressure drop, assembly tolerances and joining requirements.
A custom liquid cold plate should fit both the component and its cooling loop.
Customization can include:
Plate dimensions and component contact surfaces.
Channel geometry and coolant routing.
Inlet and outlet positions.
Mounting holes and mechanical interfaces.
Material and surface finish.
Joining process and inspection requirements.
Aluminum and copper offer different balances of conductivity, weight and manufacturing cost. Material selection must also account for coolant compatibility and the other wetted materials in the loop.
Providing clear operating data makes design review and quotation more useful.
| Required Information | What It Helps Define |
|---|---|
| Heat load and heat-source layout | Cooling demand and channel placement |
| Maximum component temperature | Thermal acceptance target |
| Coolant type and inlet temperature | Operating conditions |
| Available flow and pressure-drop limit | Hydraulic constraints |
| Working pressure | Structural and sealing requirements |
| CAD drawings and mounting details | Mechanical integration |
| Expected quantity | Manufacturing and quotation basis |
Include units and operating ranges wherever possible. If several components share one plate, identify their individual heat loads and positions.
Agree on acceptance criteria before production. Relevant checks may include dimensional inspection, mounting-surface flatness, leakage, pressure integrity and coolant flow.
A leak-free plate still needs to satisfy the application’s thermal and hydraulic requirements. Where performance testing is required, define coolant conditions, heat-source arrangement and measurement locations so results can be interpreted consistently.
KINGKA combines liquid cold plate manufacturing with precision CNC machining. Our FSW, tube and brazed capabilities provide several routes for developing application-specific cooling components.
This allows the construction method to be considered alongside the mechanical design, rather than forcing every project into one standard plate configuration.
Yes. Provide the CAD drawing together with thermal and coolant requirements so the geometry and proposed manufacturing process can be reviewed.
There is no universal choice. Compare the required cooling coverage, channel geometry, coolant compatibility, pressure drop and production quantity.
A conventional air-cooled heat sink transfers heat to surrounding air. A liquid cold plate transfers heat into coolant that transports it to another heat-rejection component.
