IGBT Heat Sink & Cold Plate Manufacturing
Custom machined cooling components for IGBT power modules, manufactured to customer drawings for industrial power electronics projects.
Cooling Components for IGBT Power Modules
BY Thermal is a custom thermal component manufacturer. We manufacture air-cooled heat sinks, liquid cold plates, machined bases and thermal assemblies according to customer 2D / 3D drawings and project requirements.
Custom IGBT Heat Sink
Custom aluminum or copper heat sinks manufactured to customer drawings. Skived, extruded + CNC and machined structures can be evaluated depending on the project.

Embedded Heat Pipe Heat Sink
Heat pipes can be embedded into suitable skived, extruded or CNC-machined heat sink bases when additional heat spreading is required.

IGBT Liquid Cold Plate
Custom liquid cold plates with CNC-machined channels, embedded copper tubes, brazed or FSW structures can be evaluated according to the customer's design.

Custom Thermal Assembly
Heat sinks, cold plates, machined housings and related thermal components can be integrated into custom OEM assemblies.

For air-cooled IGBT applications, the heat sink geometry needs to match the available airflow, installation envelope and module layout. BY Thermal manufactures the heat sink structure according to customer drawings and project requirements.
Manufacturing details to confirm
- Skiving for dense integral fin structures.
- Extrusion + CNC for profile-based heat sinks with secondary machining.
- CNC machining for mounting surfaces, holes, grooves, pockets and mechanical interfaces.
- Embedded heat pipe base when the drawing requires additional heat spreading.
Liquid-Cooled IGBT Cold Plates
For liquid-cooled IGBT projects, the channel layout and mechanical structure are reviewed against the module footprint, coolant conditions and pressure-drop requirements provided by the customer.
Cold plate project information
- CNC machined channel cold plates for flexible flow paths and mechanical features.
- Embedded copper tube cold plates for selected plate structures.
- Brazed and FSW cold plates when the construction is suitable for the drawing.
- Microchannel structures can be evaluated for projects requiring higher heat-transfer density. Actual channel capability is confirmed after drawing review.
Module Mounting Surface Matters
The mounting surface between the IGBT module and the cooler is an important manufacturing interface. Flatness, surface finish, mounting-hole position and other requirements should follow the customer's drawing or the module manufacturer's mounting specification.
Manufacturing interface review
- Flatness requirement according to drawing.
- Surface finish requirement on the module contact area.
- Hole position, datum and mounting geometry.
- Burr control around holes, slots and machined edges.
- Surface cleanliness before packing and assembly.
- Base stiffness and local mechanical structure.
- CNC dimensional inspection and interface inspection plan.

Start With Your Drawing
For IGBT cooling projects, the fastest way to review manufacturability and provide an accurate quotation is to start with your existing 2D or 3D drawing.
Whether the project uses an air-cooled heat sink, liquid cold plate or integrated thermal assembly, our engineering review is primarily based on the actual part geometry, mounting interfaces, tolerances and manufacturing requirements.
Already Have a Drawing?
Send your 2D/3D drawing together with the target quantity and basic project information. We will review the part for manufacturability, machining process, material, tolerances and production feasibility.
- 2D or 3D drawing
- Target quantity
- Material requirement
- Application / IGBT module information
- Key tolerances or mounting requirements
- Existing cooling conditions if already defined
No Drawing Yet?
If your project is still at the concept stage and no manufacturable drawing is available, paid design support can be discussed separately.
The design fee can be credited toward the subsequent product order when the project proceeds to manufacturing with BY Thermal.
