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.
