A terminal cooling structure and a cooling system for a direct-current charging device. The terminal cooling structure includes a connecting tube, conductive terminals, and a cooling tube, where the conductive terminals have sealed cavities, and at least one end of the cooling tube is disposed in the sealed cavity; and at least two conductive terminals are provided, each of the conductive terminals is provided with a connecting hole, and the connecting holes communicate with each other by the connecting tube. According to the present application, the cooling tubes are disposed in the conductive terminals, and the sealed cavities are connected to each other by water pipe joints, such that the terminal cooling structure forms a complete loop and may quickly and effectively reduce the temperature of the terminals. With the structure in which cooling liquid enters the sealed cavity from an end opening of the cooling tube and flows out of the sealed cavity from the connecting tube, the contact between the cooling liquid and the inside of the conductive terminal is more sufficient, achieving higher cooling efficiency. With the water pipe joints, the connecting tube can be mounted more conveniently and sealed more completely. A temperature sensor can monitor the cooling effect on the conductive terminals, and can provide a reference for a worker to adjust a cooling liquid supply speed.
