IGBT Cold Plates and Liquid Cooled Heatsinks for Power Electronics

GBT power modules and high-power converters operate at high currents, high voltages and demanding duty cycles. Efficient thermal management is critical to ensure reliability, lifetime and safe operation of traction inverters, wind power converters, industrial drives and HVDC systems.

ToneCooling is a specialized manufacturer of custom IGBT cold plates and liquid cooled heatsinks. We support customers from concept to mass production, providing robust, leak-tight cooling solutions for high-power electronics in harsh environments.

H2：Thermal Challenges in IGBT Power Modules

Typical power electronics applications face several cooling challenges:

• High continuous and transient losses

  • Large current and switching losses in IGBT and freewheel diodes

  • Thermal cycling due to load variations and start/stop conditions

• High reliability and safety requirements

  • Railway traction, metro systems, wind power and grid applications

  • Long service life and low failure rates required

• Limited space and complex module layouts

  • Multi-chip modules, stacked assemblies, laminated busbars

  • Electrical isolation and creepage/clearance constraints

Without proper liquid cooling, junction temperatures may exceed safe limits, leading to accelerated aging, derating or even catastrophic failure. A well-designed IGBT cold plate keeps module temperatures under control and improves overall system reliability.

H2：ToneCooling IGBT Liquid Cooled Heatsink Solutions

We design and manufacture a wide range of liquid cooled heatsinks and cold plates for IGBT power modules:

Direct-mount IGBT cold plates

• Custom cold plates matching your IGBT module footprint and bolt pattern

• Optimized flow paths under chip locations for uniform temperature distribution

• Flatness and surface quality controlled for low thermal resistance

AlSiC pin-fin heatsinks with liquid base

• AlSiC (aluminum silicon carbide) pin-fin or baseplate structures on the module side

• Integrated liquid cooling channels on the opposite side

• Combines high thermal conductivity with good CTE matching to reduce stress

Multi-module cold plates

• Cold plates designed to cool multiple IGBT modules in a single assembly

• Manifolded inlet/outlet design for even flow distribution

• Suitable for larger converters, inverter cabinets and power stacks

Our engineering team can support both standard module sizes and fully custom designs.

Typical Applications

ToneCooling IGBT cold plates are used or suitable for:

• Railway and metro traction inverters

  • Traction motor control for metro, light rail and mainline trains

• Wind power converters and pitch systems

  • High power converters in onshore and offshore wind turbines

• Industrial motor drives and soft starters

  • Variable frequency drives for heavy industry and mining applications

• HVDC, STATCOM and other grid applications

  • High power conversion and reactive power compensation systems

• High-power rectifiers and test benches

  • Electrolysis, plating and industrial rectification equipment

Each application may have specific requirements on coolant, ambient conditions, vibration and mounting – we can adapt the design accordingly.

Design and Manufacturing Capabilities

We combine thermal design, mechanical engineering and reliable manufacturing processes to provide robust IGBT cooling solutions.

Design capabilities

• Channel and manifold layout according to module hotspots

• Balancing heat transfer performance and pressure drop

• Material selection (e.g. copper, aluminum, AlSiC combinations)

• Electrical isolation considerations (e.g. interface with insulation sheets or substrates)

Manufacturing processes

• Vacuum brazing

  • For complex internal channels and high integrity joints

  • Suitable for both copper and aluminum cold plates

• Friction Stir Welding (FSW)

  • High-strength hermetic welds for aluminum cold plates

  • Good for larger, thicker plates that require mechanical robustness

• CNC machining and finishing

  • Precision machining for flatness and mounting holes

  • Surface treatment and corrosion protection where needed

H2：Testing, Reliability and Documentation

Power electronics systems demand high reliability. We can support:

• Leak and pressure testing

  • 100% pressure test at agreed test pressure

  • Helium leak test upon request

• Dimensional and flatness control

  • Controlled surface flatness for good thermal contact

  • Tolerances suitable for module mounting and sealing

• Cleanliness and coolant compatibility

  • Cleanliness levels appropriate for closed-loop coolant systems

  • Material compatibility with water-glycol and other coolants

• Documentation

  • Basic inspection records and test reports

  • PPAP Level 2 or similar documentation packages, if agreed in advance

Our goal is to deliver production-ready IGBT cold plates that can be used confidently in long-life, safety-critical systems.

How to Start an IGBT Cooling Project with ToneCooling

To evaluate a custom IGBT cold plate or liquid cooled heatsink, you can start with the following information:

• IGBT module type and manufacturer

• Power dissipation (continuous and peak)

• Coolant type, inlet temperature and allowable pressure drop

• Mechanical drawings (module outline, bolt pattern, isolation requirements)

• Environment and application (railway, wind, industrial, grid, etc.)

• Expected annual volume and project schedule

Based on this information, we can provide:

• An initial cooling concept and layout suggestion

• A quotation for prototypes and mass production

• Recommendations on materials and test levels

FAQ – IGBT Cold Plates and Liquid Cooled Heatsinks

Q1: Can you design cold plates for specific IGBT module types?
Yes. We can design cold plates for specific module outlines, including mounting hole patterns and clearance areas. 3D or 2D drawings are very helpful.

Q2: Do you support AlSiC or other advanced base materials?
We can integrate AlSiC pin-fin or baseplate parts with liquid cooling structures, depending on your design and supply chain. Details can be discussed case by case.

Q3: What coolants do you support for IGBT cold plates?
Typical coolants include water-glycol mixtures and treated water. If your application uses other coolants, we will review material compatibility and adjust the design accordingly.

Q4: How do you ensure leak-tightness over long-term operation?
We use vacuum brazing or FSW processes for hermetic joints and perform 100% pressure testing according to agreed standards. Helium leak testing is available when required.

Q5: Do you offer prototypes before mass production?
Yes. We usually build prototype or pilot batches for validation in your system. After successful testing, we can scale up to mass production.

Q6: Can you provide documentation such as PPAP?
For automotive or other highly regulated applications, we can provide documentation support such as PPAP Level 2 if this is defined in the project scope.
