摘要

根据高功率二极管激光器的散热需求,设计了一种储能式相变冷却实验系统,并开展了喷雾相变冷却器和微通道相变冷却器的设计。采用多孔微结构的换热表面,用氨做制冷剂,实现了喷雾相变冷却器表面温度37 ℃时,散热功率密度达到了511 W/cm2。采用节流汽化原理,分别设计了背冷式相变微通道冷却器和薄片型的模块式相变微通道冷却器,背冷式相变微通道冷却器采用氨做制冷剂,散热功率密度达到了550 W/cm2,采用R124做制冷剂,散热功率密度约270 W/cm2。采用R124做制冷剂,实现了脉冲激光功率3 kW和连续激光功率100 W的相变冷却二极管激光器模块封装。

Abstract

We designed a phase transition cooling system with thermal energy storage solutions, and designed a spray phase transition cooler and microchannel phase transition coolers that meet the need of heat dispersion for high power diode laser. By use of NH3 as cryogen, the cooler with porous heat exchanging surface achieved a heat flux density up to 511 W/cm2 while the surface temperature was 37 ℃. A back cooling phase transition microchannel cooler and a thin piece shaped phase transition microchannel cooler had been designed by using throttle evaporation principle. The dispersed heat flux density of 550 W/cm2 and 270 W/cm2 was proved by the back cooling phase transition cooler with NH3 and R124 as cryogen, respectively. The diode laser modules with power of QCW 3 kW and CW 100 W were packaged based on phase transition cooler with R124 as cryogen.
