CATEGORIESCUSTOM THERMAL ASSEMBLIES / OEM MANUFACTURING
Hongming Sheng manufactures custom heatpipe heat sink assemblies based on customer drawings and thermal requirements. We combine copper heatpipes, aluminum bases and fin structures for equipment with limited cooling space.
Our manufacturing support includes base machining, heatpipe routing, fin integration and assembly. Share your heat load, available space and cooling conditions so the configuration can be reviewed before quotation.

A heatpipe transfers heat through evaporation and condensation of a sealed working fluid. Integrated into a heat sink, it can transport heat from a concentrated source toward a larger fin area. The fins then release heat to the surrounding air.
The assembly should be evaluated as a complete cooling system. Contact quality, pipe layout, fin spacing, installation orientation and available airflow all need consideration. Natural convection or fan-assisted cooling is selected according to the application.
| Assembly Feature | Details to Confirm |
|---|---|
| Aluminum Base | Overall dimensions, thickness, contact surface, groove geometry, mounting holes and flatness requirements. |
| Heatpipe Layout | Pipe quantity, diameter, routing and clearances around fasteners or other equipment. |
| Fin Structure | Extruded or skived fin configuration, height, spacing and orientation within the available cooling space. |
| Joining Method | Press-fitting, soldering or thermal bonding, reviewed for the specified materials and assembly requirements. |
| Finish & Interfaces | Surface treatment, contact areas, mounting hardware and any surfaces that require masking or special handling. |
• Power Electronics: Cooling assemblies for IGBT, MOSFET, rectifier and inverter modules.
• EV Electronics: Heat sinks for control units and power conversion equipment.
• Telecom & Servers: Compact assemblies for electronics with concentrated heat sources.
• Lighting & Industrial Power: Custom cooling components designed around the equipment's operating conditions.
Review the contact surface, pipe route, fin configuration and mounting layout. Confirm dimensions, tolerances and assembly details before machining.
Machine the base and grooves, prepare mounting features, and integrate the heatpipes and fins using the agreed joining method.
Check critical dimensions, contact surfaces and assembly condition. Thermal evaluation should use agreed heat loads, airflow, measurement locations and temperature limits. Any leak or reliability testing requirements should be defined in the project specification.
After sample approval, confirm the production configuration and inspection criteria. Packaging should protect fins, heatpipes and contact surfaces during transport.
Send the following information for engineering review and quotation:
• Drawing: 2D drawing and/or 3D CAD model, including mounting details.
• Heat Source: Heat load in watts, contact area and heat-source locations.
• Temperature Conditions: Ambient range and allowable component or base temperature.
• Cooling Conditions: Natural convection or fan-assisted airflow, with fan or duct information where available.
• Installation: Space envelope, orientation and clearance restrictions.
• Order Requirements: Quantity, finish, inspection needs and target delivery date.
Our team can review the proposed manufacturing route and confirm quotation scope and lead time.
