A low-temperature intelligent pulse heating circuit for power batteries, a power battery, and an automobile are disclosed, relating to the field of new energy vehicles. The circuit includes: a first relay, an inductor, a first switching transistor, and a second switching transistor. The first and second switching transistors have parasitic diodes with reverse conduction, or the switching transistors include a switch body and a diode connected in reverse parallel with the switch body. One end of the inductor is connected to the common terminal of the first and second battery packs, and the other end of the inductor is connected to the common terminal of the first and second switching transistors. The other ends of the first and second switching transistors are respectively connected to the other ends of the first and second battery packs. The branch formed by the first and second switching transistors is connected in parallel with the vehicle's bus capacitor. This circuit provides a reliable hardware foundation for achieving rapid and uniform heating of the battery pack.

The utility model relates to the technical field of cooling systems, in particular to a medium-frequency electric furnace water cooling system which comprises a medium-frequency electric furnace, a first cooling device, a second cooling device, a water tank and a cooling water pipe. The cooling water pipe is hermetically connected with the first cooling device, the second cooling device and the water tank to form the closed cooling loop, so that cooling water for cooling the medium-frequency electric furnace is closed in the circulating process, the cooling water cannot leak or evaporate, water resources are fully utilized, and waste of the water resources is avoided; besides, the first cooling device and the second cooling device are provided with heat exchange mechanisms, compressors, condensers and pressure reducers which are sequentially connected, cooling water circularly flows to rapidly absorb and release heat, a plurality of cooling fins are arranged on a cooling water pipe and have large contact area with the cooling water pipe, heat in the cooling water is guided out, and the cooling effect of the cooling water is improved. And the effect of efficiently and circularly cooling the medium-frequency electric furnace is achieved.
