What is a Composited heat sink?

A composite heat sink refers to a heat dissipation component that is formed through a specific process by combining two or more materials with different thermal and mechanical properties (such as metals with metals, metals with ceramics, metals with polymers, etc.).
 
The core design concept of a composite heat sink is "complementary advantages and coordinated performance" - it breaks through the performance limitations of a single material and achieves multi-dimensional optimization of "thermal conductivity efficiency, structural strength, lightweight, and cost control" through material combination. In particular, it addresses the pain points of traditional pure metal heat sinks (copper/aluminum) in terms of thermal expansion matching, weight control, or adaptability to extreme environments.

Winshare Composited heat sink Customization Solution

hx
Winshare is committed to providing customers with excellent customized thermal management solutions. We know that each project has its own unique needs and challenges, so we do not provide a "one-size-fits-all" product, but through a deep understanding of your specific application, we tailor the most optimized and efficient bonded fin heat sink.
Group 1321314558
In-depth communication and assessment of needs
 
We will discuss your requirements in detail to fully understand your heat source characteristics, heat load, available space limitations, operating environment conditions (such as temperature, airflow type and velocity), target temperature, and any special performance requirements for the heat sink, such as noise, weight, and lifespan. We will also confirm the connection method between the heat sink and the heat source to ensure optimal heat transfer efficiency.
 
 
 
Group 1321314557
Professional thermal design and simulation optimization
 
Our team of experienced thermal design engineers utilizes industry-leading computational fluid dynamics (CFD) and finite element analysis (FEA) software to accurately simulate the heat sink's thermal performance, internal airflow distribution, and pressure drop under various operating conditions. During the design phase, key parameters such as fin height, spacing, wave form, and material thickness are comprehensively considered. Multiple rounds of iterative optimization ensure that the design closely matches actual operating conditions. Calibration using big data improves the success rate of first-time designs.
 
03
Advanced materials and manufacturing process selection
 
Based on factors such as thermal conductivity, weight, cost, and corrosion resistance, we recommend and utilize high-quality materials such as pure copper (C1100) and aluminum alloys (A6061, A6063). Winshare boasts industry-leading manufacturing capabilities, enabling us to select the most suitable and efficient processes based on design complexity and volume requirements, including precision folding, vacuum brazing, reflow/spot welding, and high-precision CNC machining.
 
 
Group 1321314560
Prototyping and rigorous validation
 
Once the design is finalized, we will quickly produce high-precision prototypes. In Winshare's well-equipped thermal testing lab, we conduct comprehensive thermal performance tests (such as thermal resistance and temperature rise) and reliability tests (such as thermal cycling, vibration shock, and salt spray corrosion) to ensure that performance fully meets design specifications and your expectations. All test data is carefully recorded and shared with customers.
 
 
04
Mass production and lean quality control
 
Once the prototype is validated, we'll initiate efficient mass production. Winshare strictly adheres to the ISO 9001 quality management system, implementing meticulous management and strict quality control at every stage, from raw material procurement, production and processing to final product shipment. We utilize advanced automated production equipment and high-precision testing instruments to ensure high consistency, superior quality, and long-term reliability in every batch of products, minimizing your risk.

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.
