An electrical device with vents is provided. The electrical device comprises a case, a sliding part, a spring, and an electromagnetic coil. The case comprises a first vent and a sliding assembly. The sliding assembly is installed at one side or both sides of the first vent, and the sliding part is movable along the sliding assembly. The spring and the electromagnetic coil are separately on each side of the sliding part. When this electrical device detects that heat should be removed, the electromagnetic coil is powered for generating magnetic force to stretch the spring and move the sliding part to the first position to open the first vents. When the electromagnetic coil is not powered, the spring pulls the sliding part back to the second position to close the first vent.
