A coil device for an electronic expansion valve. The coil device comprises a detachable housing and a stator winding provided in an inner cavity of the housing. A flow channel is provided on the housing. An inlet of the flow channel is in communication with a pouring port, and an outlet thereof is in communication with the inner cavity of the housing; or an injection molding material reaches an end surface of the housing through an injection molding channel, and forms a positioning element on the end surface of the housing. This coil is avoided from using a welding manner to be connected to the housing, thereby avoiding electrochemical corrosion caused by a welding process, prolonging the service life of the coil device, further simplifying the procedure of mounting of the positioning element and the housing, reducing the manufacturing costs of the coil device, and preventing damage of the coil device. Also provided is an electronic expansion valve using the coil device. |
