The invention relates to an automobile thermal management system which comprises a refrigerating medium loop, the refrigerating medium loop comprises a compressor, an air conditioner box, a first branch and a second branch, the air conditioner box comprises an evaporator and a condenser, an inlet of the condenser communicates with an outlet of the compressor, and an outlet of the condenser communicates with an inlet of the evaporator through the first branch. The first branch is communicated with an inlet of the compressor through a second branch, an outlet of the evaporator is communicated with the inlet of the compressor, and a first throttling piece is arranged on the first branch so as to control the flow of a refrigerating medium flowing into the evaporator and conduct throttling and pressure reduction on the refrigerating medium flowing into the evaporator. Two branches are arranged in the refrigerating medium loop, a high-temperature and high-pressure refrigerating medium flowing out of the compressor flows into the condenser and releases heat in the condenser, the refrigerating medium subjected to heat exchange is divided into two paths, one path flows into the evaporator through the first branch to lower the surface temperature of the evaporator, and the other path directly flows back to the compressor through the second branch to lower the surface temperature of the evaporator. And dehumidification at different temperatures is met through shunting.
