The invention discloses an efficient heat management system based on a loop heat pipe. The efficient heat management system is used for a certain large-aperture optical load. The load is provided with a plurality of optical imaging channels, the position distribution is relatively dispersed, and the total power consumption is about 2800W. Wherein two infrared channels are provided with four refrigerators which provide refrigeration for the medium-long wave lens group, the long-wave lens group and the focal plane. The refrigerator works on the rail for a long time and continuously heats. The system can carry more than several times of heat source heat through waste heat power consumption of the refrigerating machine, and the effective heat transfer capacity of the loop heat pipe is remarkably improved; and meanwhile, a phase-change material is supplemented and applied to a periodic working heat source of a spacecraft, so that the driving power consumption of the evaporator can be further saved, and efficient heat dissipation of the large-aperture optical load focal plane assembly is realized.
