针对国内激光脱毛设备的需求,提出了宏通道加传导散热热沉的散热设计,并采用正交实验方法对影响宏通道散热能力的4个关键参数和3个水平进行了结构优化设计。仿真结果表明,对于该模块,本文设计的宏通道具有和微通道相同的散热能力。使用宏通道加传导散热热沉研制出低成本半导体激光器模块,测试结果表明,与设计值一致,输出峰值功率达到了603 W,波长807.5 nm,整体结构热阻为0.28℃/W,可以满足激光脱毛设备的使用要求。宏通道热沉成功取代了传统的微通道热沉,达到了降低成本的目的。
According to the demand of laser hair removal equipment in our country, the heat dissipation design of macro channel and conduction heat sink is proposed. The orthogonal design is used to optimize the design of four key parameters and three levels which affect the cooling capacity of macro channel. The simulation results show that for this module, the macro channel designed in this paper has the same heat dissipation capacity as the microchannel. The results show that the peak output power reaches 603 W and the wavelength is 807.5 nm. The thermal resistance of the whole structure is 0.28 ℃ / W, which can meet the needs of laser Use of hair removal equipment. The macro channel heat sink has successfully replaced the traditional microchannel heat sink to achieve the purpose of reducing costs.
