Multi-objective optimization design method for thermal structure of forced air cooling heat dissipation system

Abstract

The invention discloses a multi-objective optimization design method for a thermal structure of a forced air cooling heat dissipation system. According to the method, from the perspective of multi-objective optimization, firstly, an optimization design problem of the thermal structure of the forced air cooling heat dissipation system is converted into one typical multi-objective constraint optimization problem simultaneously considering performance indexes such as heat resistance, pressure drop, total weight and the like of the heat dissipation system, and then optimization solution is carriedout by adopting a genetic optimization solution method based on non-dominated sorting, so that the optimal thermal structure design parameters meeting the requirements of the multi-performance indexes such as the heat resistance, the pressure drop, the total weight and the like of the heat dissipation system are obtained. Through the adoption of the method, a compromise design proposal simultaneously considering the requirements of the multi-performance indexes such as the heat resistance, the pressure drop, the total weight and the like of the heat dissipation system can be obtained; and furthermore, the method has an advantage that the existing technology does not have, and the advantage is that the total weight of the designed forced air cooling heat dissipation system is smaller undera condition that the same thermal resistance and pressure drop performance of the heat dissipation system are ensured.
