The specific structure of the cold plate 500 is not limited in the embodiment of the present application.

[0057] The shell 100 has a mounting cavity, and the electronic component assembly 200 is arranged in the mounting cavity.

Without affecting heat conduction, the control panel 300 can be better protected from short circuit, and the safe use of the control panel 300 is protected.
