The present application relates to an isolation device and an electric vehicle. The isolation device includes a battery mounting seat, an isolation cover, a heat dissipation mechanism and a drainage pipe. The isolation cover is arranged on the battery mounting seat, the isolation cover and the battery mounting seat are enclosed to form a first cavity for accommodating the battery, and a second cavity for filling the heat storage fluid is arranged inside the isolation cover. The heat dissipation mechanism includes a fan blade, an impeller and a rotating shaft. Both the fan blade and the impeller are fixedly connected with the rotating shaft, and the rotating shaft is rotatably connected to the top of the isolation cover. One end of the draft tube is connected to the top of the isolation cover, and the other end is configured to extend toward the direction close to the impeller. Wherein, when the heat storage fluid reaches the preset temperature, it can change from liquid state to gaseous state, and the gaseous heat storage fluid can be blown from the second cavity to the impeller through the drainage pipe, so that the impeller drives the fan blades to rotate, so that the fan blades can drive the air through the top of the isolation hood. The above isolation device has good heat insulation effect, and can effectively prevent the fire from spreading when the battery spontaneously ignites. |
