Abstract:

With successful development of LED lamps, the dissipation of LED lamps has become the core problem. If the heat produced during the work cant be loss in time, the high temperature of the lamps will affect their service lives or even damage the LED permanently. In this paper, based on the principle of finite element method, using thermal simulation software, the effect of the geometric characteristics micro-structure of the heat exchanger combining polymer micro-scale fins and metal base on the heat transfer characteristics was simulated. The impact of the fin width, wing fin pitch, fin height and thickness of the substrate on the tablet microstructure heat transfer characteristics was analyzed. The results provide some technical reference for the design and application of the micro heat exchanger.
