Abstract: A harmonica-shaped tube, a harmonica-shaped tube type heat exchanger and a vehicle are provided. The harmonica-shaped tube includes a plurality of flow channels arranged at intervals. Inner walls of at least some flow channels include protrusions protruding in a direction approaching centers of the flow channels and/or include recesses recessing in a direction away from the centers of the flow channels. The protrusions and recesses enable a liquid fluid (e.g., refrigerant) to nucleate rapidly, and can also burst large nucleuses which grow in a disorderly manner, thereby preventing the large nucleuses from forming boundary layers on inner walls of the plurality of flow channels, such that nucleuses can be separated from inner wall surfaces rapidly. Therefore, heat exchange performance of the harmonica-shaped tube is improved, and heat exchange requirements of a traction battery are satisfied.

Abstract: A battery pack includes a controller, a battery core, a liquid leakage detector, and a pre-charge switch. The liquid leakage detector is connected with the controller, and the liquid leakage detector is configured to send a liquid leakage signal to the controller when detecting that liquid leakage occurs in the battery core. The controller is configured to prohibit sending a pre-charge on signal to the pre-charge switch upon receiving the liquid leakage signal while receiving a start signal for starting the battery core. The pre-charge switch is configured to prohibit connection of the pre-charge voltage end and the power output end when not receiving the pre-charge on signal, to prohibit the battery core from outputting a pre-charge voltage through the power output end.
