A plurality of radiating fins 19 are vertically arranged on the first partition plate 113 and the second partition plate 123, and heat generated by the electric core assembly 20 can be transferred to the radiating fins 19 through the first partition plate 113 and the second partition plate 123, and then the surplus heat is taken away through wind flow. In this embodiment, the first housing 11 further includes a main body portion and a cover plate, the main body portion is fastened to the second housing 12, and the cover plate is disposed on a side of the main body portion away from the second housing 12. The cover plate is also provided with an opening corresponding to the connector 50 so that the connector 50 can be connected to an external device.

Although the present application has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the present application.
