OEM LIQUID COOLING COMPONENTS

Embedded Copper Tube Cold Plates for Industrial Liquid Cooling

Hongming Sheng manufactures custom copper tube embedded cold plates for power electronics, energy systems and industrial equipment. Copper tubing is integrated into a machined aluminum base to create a liquid cooling assembly that follows your drawing and installation requirements.

We support base machining, tube routing, connection features and final assembly, from prototype samples to repeat production. The design review considers the heat-source layout, coolant conditions and mechanical interfaces together.

Copper Tube Cold Plate Samples

These reference assemblies show different plate and tubing configurations. Dimensions, tube paths and port positions are customized for each project.

01 / Define the Cold Plate Configuration

The copper tube provides the coolant path, while the aluminum base provides the mounting structure and heat transfer interface. Tube retention and contact between the tube and plate are reviewed with the selected assembly method.

02 / Match the Plate to the Cooling Loop

A useful review includes the coolant type, inlet temperature, flow rate and allowable pressure drop. These conditions help define the tube path and connection requirements for the customer's cooling circuit.

Identify the heat-source locations, contact footprint and allowable component temperature. Critical flatness and surface finish should be specified on the mounting face so the plate can be inspected against clear requirements.

Material and fluid compatibility should be reviewed for the complete wetted path, including the copper tubing, fittings and seals.

03 / Agree Inspection and Test Requirements

Dimensional and Assembly Checks

Inspection covers the specified base dimensions, mounting features, contact surface, tube routing and connection positions. Prototype review helps confirm fit before repeat production.

Pressure and Leak Testing

Each finished cold plate is leak checked according to the agreed inspection plan. Requests for pressure testing up to 5 bar are reviewed for the specified tubing, fittings and assembly. Confirm the test medium, hold time and acceptance criteria before production.

Operating pressure and test pressure are specified separately. Provide both requirements, together with the operating temperature range.

Thermal and Flow Validation

Where performance validation is required, define the heat load, coolant, inlet temperature, flow rate, measurement locations and acceptance limits before sample evaluation.
