Heatsinks Design Assistance

Heatsinks, standard or custom. The effects of Increasing power electronics demand innovative thermal designs. Consequently, these devices have significantly different junction temperatures and different working environments; therefore, custom design heatsinks are necessary to improve the system’s performance and reliability.

Briefly, as part of design work, our engineers apply advanced 3D modeling. Also, we are using cutting-edge CFD tools to optimize your heat transfer project. In addition, we provide our customers with a complete cooling solution to meet specific requirements in a timely and cost-effective manner.

Also, you can count on our Mechanical Engineers to assist with design change and reduce manufacturing costs.

Our fully equipped lab is available to validate your designs, test, and inspect.



What is a custom heatsink and its benefits:

A custom heatsink is a heatsink that is specifically designed and manufactured for a particular application or device. Compared to standard heatsinks, custom heatsinks offer several benefits, including:

1. Optimal thermal performance: Custom heatsinks can be designed to fit the specific thermal requirements of the device, ensuring optimal cooling performance. This can result in lower operating temperatures and improved device reliability.

2. Tailored design: Custom heatsinks can be designed to fit the specific dimensions and layout of the device, allowing for more efficient use of available space. This can be especially important in small form factor devices where space is limited.

3. Materials selection: Custom heatsinks can be manufactured using a variety of materials, including copper, aluminum, and other high-performance alloys. The choice of materials can be tailored to the specific thermal requirements of the device, as well as the desired cost and weight.

4. Branding and aesthetics: Custom heatsinks can be designed to reflect the branding and aesthetics of the device, creating a more cohesive and visually appealing product.

5. Improved manufacturing efficiency: Custom heatsinks can be designed with manufacturing efficiency in mind, reducing the time and cost required to produce the device. This can be especially important for high-volume production runs.

Overall, custom heatsinks offer a range of benefits over standard heatsinks, including improved thermal performance, tailored design, and more efficient manufacturing.
