What is a Bonded Fin Heat Sink?

Winshare Thermal provides Composited Heat Sinks, a highly efficient thermal solution designed for applications requiring large surface areas and complex airflow. This technology involves firmly attaching individual, high-density fins into grooves on a base plate using a high thermal conductivity epoxy or a brazing process.
 
This method overcomes the height limitations of extrusion, allowing us to utilize taller, thinner fins. This significantly maximizes the heat dissipation surface area in a constrained volume, making it ideal for high-power forced convection cooling.

Customized Case (Example)

Regardless of the size of your project, Winshare can provide you with customized bonded fin heat sink solutions to help you achieve the best performance.

New Energy Vehicle Electronic Control System

Challenges: High power density, tight installation space, severe vibration and temperature cycling.
Winshare solution: A copper-aluminum composite bonded fin heat sink is used. The copper substrate is used to quickly conduct the heat of the IGBT module, and the aluminum fins reduce the overall weight. High reliability is ensured through precision brazing process, and the fin spacing is optimized to adapt to high-efficiency heat dissipation under forced air cooling conditions.

Large Energy Storage System Inverter

Challenge: Continuous high power output and long-term stable operation require strict restrictions on the size of the heat sink.
Winshare solution: Designing an oversized bonded fin heat sink maximizes the heat dissipation surface area by optimizing the fin height and density. Combined with internal heat pipe technology, it evenly disperses heat and ensures the temperature stability of the inverter under long-term full-load operation.

The Answers to Your Questions Are Here.

  • Q How to get a quote for Winshare Composited heat sink?

    A
    Please contact our sales representative through our official website or directly. In order to provide the most accurate quotation, please provide as much detailed information as possible, including: design drawings (if any), detailed technical requirements (such as target heat dissipation power, space dimensions, airflow conditions, ambient temperature, etc.) and expected purchase quantity. Our team will provide you with a professional quotation as soon as possible.
     
  • Q Are Composited heat sink reliable in harsh environments?

    A
    Winshare's Composited heat sink take all kinds of harsh working conditions into full consideration during design and manufacturing. We conduct multiple reliability tests (such as thermal shock, vibration, salt spray corrosion, etc.) to ensure that the product can maintain excellent stability and long-term reliability in harsh environments such as a wide temperature range, high humidity, vibration shock, etc.
     
  • Q Can Winshare provide thermal management consulting for our specific applications?

    A
    Of course! Our professional thermal design team has rich industry experience and can deeply analyze your specific application scenarios and challenges, and provide comprehensive and customized thermal management consulting and solution recommendations from conceptual design, thermal simulation, structural optimization to final product implementation.
     
  • Q How to evaluate the heat dissipation performance of Winshare Composited heat sink?

    A
    We use double protection: first, in the design stage, we use advanced CFD thermal simulation software to make accurate performance predictions; second, after the prototype is completed, we will conduct rigorous thermal resistance testing, wind resistance testing and other necessary performance verifications in our professional thermal conduction laboratory, and provide detailed test reports to ensure that the product performance fully meets your design requirements.
     
  • Q How long is the cycle for customizing Winshare Composited heat sink

    A
    The customization cycle depends on the complexity of the design, material selection and order quantity. Generally, it takes about 3-5 weeks from the final confirmation of the design plan to the delivery of prototype samples. The cycle of mass production will be confirmed separately according to the specific order quantity and schedule. We will provide a detailed project schedule.
     
  • Q What material combinations can be used for Winshare's Composited heat sink?

    A
    We offer a variety of flexible material combinations, including but not limited to: aluminum substrate + aluminum fins, aluminum substrate + copper fins, copper substrate + copper fins, and copper substrate + aluminum fins.

  • Q What are the main advantages of Composited heat sink compared to extruded heat sinks?

    A
    Composited heat sink can achieve a higher fin height to pitch ratio (i.e., a higher aspect ratio), providing a larger heat dissipation surface area, and are particularly suitable for large-size and high-power heat dissipation requirements. At the same time, it far exceeds the extrusion process in terms of size, material combination (such as copper-aluminum composite) and design flexibility, and can meet more stringent high-power heat dissipation requirements.
