The invention relates to the technical field of optical fiber laser cooling, and provides an airborne optical fiber laser cooling module and an optical fiber laser with the module, the airborne optical fiber laser cooling module comprises a heat dredging plate and a cover plate, the lower surface of the heat dredging plate is provided with two supporting plates in parallel, a plurality of streaming columns are arranged between the two supporting plates, and the upper surface of the heat dredging plate is provided with an optical fiber mounting groove; the head end and the tail end of the optical fiber mounting groove penetrate through the side wall of the heat dredging plate and respectively form an optical fiber inlet and an optical fiber outlet; a heat dredging cavity is formed between the upper surface and the lower surface of the heat dredging plate, a capillary structure layer is arranged on the inner wall of the heat dredging cavity, and the heat dredging cavity is filled with a liquid working medium. The device can realize ingenious combination of dredging type heat pipe passive cooling and external incoming flow active cooling through a simple structure, improves the cooling efficiency, enhances the cooling effect, saves power and weight, and reduces the cost. The technical problems that in the existing water cooling technology, complex accessory devices and extra power are needed to maintain liquid flowing and working medium circulation, so that the aircraft load burden is increased, and liquid leakage possibly causes failure of an optical fiber laser are solved.

    本发明涉及光纤激光器冷却技术领域,提供一种机载光纤激光器冷却模块及具有该模块的光纤激光器,包括热疏导板、盖板,热疏导板下表面平行设有两个支撑板并在两支撑板间设多根绕流柱,热疏导板上表面设光纤安装槽,光纤安装槽的首端、尾端均贯穿热疏导板的侧壁并分别形成光纤入口、出口;热疏导板的上下表面之间开设有热疏腔体,热疏腔体内壁设有毛细结构层且内部充有液体工质。本发明能够以简单结构实现疏导式热管被动冷却与外界来流主动冷却的巧妙结合,提升冷却效率,增强冷却效果,节省动力与重量,解决现有水冷技术需复杂附属装置及额外动力来维持液体流动和工质循环而增加飞行器载荷负担及液体泄漏可能导致光纤激光器失效的技术问题。
