AI Technical Summary

Technical Problem

Standard cooling systems for power sources, such as combustion engines or fuel cells, are often over-dimensioned for vehicles or installations that do not operate at full load, leading to unnecessary weight, size, and cost, as well as potential inefficiencies due to the difficulty in accurately dimensioning the cooling system for varying usage scenarios.

Method used

A modular cooling system comprising interchangeable heat exchanger modules that can be assembled in series or parallel to match the specific cooling requirements of the power source, allowing for flexible configuration and easy replacement of damaged sections, with a fan electronic control unit to optimize fan operation based on actual cooling needs.

Benefits of technology

The modular system enables a customized cooling solution that saves space and weight while ensuring optimal performance by allowing the cooling capacity to be tailored to the actual power usage, reducing costs and improving efficiency by allowing for the use of fewer and more appropriately sized components.
