Test device for monitoring evaporative heat dissipation cooling effects of large-scale embankment

The invention discloses a test device for monitoring an evaporative heat dissipation cooling effect of a large-scale embankment. The test device comprises an outer test box, an embankment model test box, an indoor air circulation control system, an air drying control system, a sun illumination simulation control system, a moisture compensation control system and a data acquisition test system, wherein the outer test box is internally provided with an inner test box; the embankment model test box is used for filling an embankment model; the indoor air circulation control system is used for controlling the internal temperature or airflow direction of the outer test box or the inner test box; the air drying control system is used for controlling the internal humidity of the internal test box;the sun illumination simulation control system is erected above the embankment model and used for controlling the light radiation quantity; the moisture compensation control system is erected above the embankment model and u
