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.
