If the rotary shell 1 is provided with fan blades, the electric control output component can be an electric control fan which can output wind power to the outside so as to meet the functional requirements of cooling, heat dissipation and the like, and during specific assembly, the electric control fan can be arranged on a shell of the evaporator waiting for the heat dissipation component; of course, the rotating shell 1 may be configured in other structural forms, which may be exchanged in specific practice as long as the use requirement can be met.

Based on the existence of the grooves 413c, a reinforcing rib 413d can be formed between two adjacent grooves 413 c; if viewed from another perspective, the support foot 413 in this form can also be understood as a combination of a flat plate and several reinforcing ribs 413d, the reinforcing ribs 413d being used for strength enhancement.

In addition to the support legs 413 of various forms, a reinforcing rib 45 may be connected between the central portion 411 and the outer edge portion 412 to further improve strength.
