Abstract
A water-cooling structure for electric motor includes a motor main body, a heat-dissipation base, and a vortex-forming section. The motor main body is externally fitted around the heat-dissipation base. The heat-dissipation base is provided around an outer circumferential surface with at least one main flow passage. The vortex-forming section is provided in the main flow passage to create vortex effect on a type of cooling liquid flowing in the main flow passage, so as to enable an increased heat transfer efficiency of the water-cooling structure.
