Abstract: The present disclosure provides a positive-pressure-withstanding high-power flat evaporator, processing methods thereof and a flat loop heat pipe including the evaporator. The evaporator includes a housing, and reinforcing ribs and a capillary wick which are positioned inside the housing, and the arrangement of the reinforcing ribs can ensure that the strength of the whole evaporator is capable of withstanding positive pressure. The capillary wick is composed of four parts, namely, an evaporating wick, a heat insulating wick, a sealing wick and a transfer wick. Through the large permeability of the transfer wick, liquid supply with low flow resistance can be realized, the heat transfer capability of the loop heat pipe is greatly improved, and the problems of long liquid supply path and large flow resistance caused by a large-area evaporator are solved.
