The invention discloses an aluminum shell resistor based on evaporative cooling. The resistor comprises a shell and a resistor assembly, the resistor assembly comprises a resistance wire, a resistor core, a tube shell, a liquid absorption core and water. The hollow tube shell is mounted in the resistor core, the liquid absorption core is arranged on the inner wall of the tube shell, and water is filled into the tube shell after the tube shell is vacuumized, so that compared with an original solid resistor core, the weight of equipment is greatly reduced, in addition, after heat of the resistance wire is transferred to the tube shell, water evaporates to absorb latent heat, and the temperature of the resistance wire is reduced; the shell is filled with the quartz sand, the quartz sand is small in heat conductivity coefficient, and the heat conduction process in the resistor plays a leading role in a long time, so that the speed of reaching a melting point when the resistor is short-circuited is directly slowed
