Cooling medium discharge structure of double-stator motor

The invention provides a stator cooling device and a motor. The stator cooling device comprises a housing, first barrier members and second barrier members, wherein the housing comprises a cooling channel with a cooling inlet and a cooling outlet; the cooling channel is used for accommodating a stator unit; the stator unit comprises tooth parts and coil parts; the tooth parts extend in the radial direction and are fixed in the cooling channel; the periphery of each tooth part is sleeved with one coil part; the first barrier members and the second barrier members are located on the two radial sides of the tooth parts and fixed between the coil parts and the housing; the first barrier members and the second barrier members are arranged in a staggered mode so as to allow a cooling medium to sequentially pass through a space between every two adjacent coil parts and prevent the cooling medium from flowing back. According to the invention, cooling efficiency is effectively improved, and cooling effect is further i
