The invention discloses a thin-wall part mounting base additive manufacturing deformation control method and a cooling device. The thin-wall part mounting base additive manufacturing deformation control method comprises the following specific steps that firstly, a mounting base model is established through computer three-dimensional cartographic software, machining allowance is added, and a mounting base blank model is obtained; step 2, carrying out hierarchical slicing on the model by using software to obtain a processing path of each slice layer; thirdly, a cooling device is fixed to the opposite side face of the to-be-machined surface of the thin-wall part, the cooling device is started, and the temperature of cooling liquid is set; by adopting the thin-wall part mounting seat additive manufacturing deformation control method and the cooling device, the cooling liquid is in direct contact with the surface of the thin-wall part to be machined, and local cooling in the additive manufacturing process is achie
