摘要

针对大功率LED汽车前照灯的结构、性能要求，提出了基于热电制冷效应的散热方案，并对不同类型散热系统散热性能进行了试验研究。结果表明：半导体制冷器对外部风扇风速或冷却液流速的敏感性分别高于风冷和液冷散热装置，模型一（风冷+热电制冷）和模型二（液冷+热电制冷）的制冷片最佳工作电流分别为3.0 A和5.0 A。当环境温度在极限范围（60~65 ℃）时，计算得到芯片的结温为55.5 ℃，光通量为1 458.8 lm。所设计的基于热电制冷散热系统可以满足使用要求。

Abstract

The enhanced cooling models based on thermoelectric effect were presented to meet the thermal demand of high-power LED headlight. The cooling performance of different device was evaluated and compared through measuring the LED case temperature. It is found that the thermoelectric cooler is more sensitive to the external fan speed than the purely enforced air cooler. In addition

the optimal drive currents for the model one (air cooling+TEC) and model two (liquid cooling+TEC) are 3 A and 5 A

respectively. When the ambient temperature within its limit level (60-65 ℃)

the junction temperature can be calculated to be 55.5℃

and the output light is 1 458.8 lm.
