The invention discloses a lower shell assembly of an evaporator of an automotive air conditioner and relates to the technical field of automotive air conditioners. The lower shell assembly comprises alower shell of the evaporator and a water pan, wherein the lower shell of the evaporator is provided with an accommodation cavity opened upward, and a drain outlet is formed in the outer side of theside wall of the lower shell of the evaporator; a catch basin communicating to the drain outlet is arranged at the bottom of the accommodation cavity; the water pan is of a long straight slot structure opened in two ends, and a plurality of drainage holes are formed in the bottom of the water pan; the upper ends of the slot walls on two sides of the water pan are folded outward to form a first turnup and a second turnup, separately, and a plurality of protrusions distributed in a spaced manner in the length direction of the first turnup are arranged on the lower side of the first turnup; a front side supporting table for supporting the first turnup and a back side supporting table for supporting the second turnup are arranged on two sides of the catch basin, separately, grooves matched with the grooves one by one are formed in the front side supporting table, and baffle blocks matched with the back side supporting table are arranged on the inner wall of the accommodation cavity. The lower shell assembly overcomes the problem that the water outlet and drainage effect on the drain outlet of the automotive air conditioner is poor in effect and the integral design space is optimized.
