The invention relates to a battery pack tab cooling structure, a battery pack and a vehicle with the battery pack. The battery pack tab cooling structure comprises a tab connecting element, an insulation heat conduction block and a liquid cooling plate, wherein the tab connecting element comprises a first support arm, a second support arm and a third support arm; the first support arm and the second support arm are electrically connected with two tabs of two adjacent battery cells of the battery pack; the insulation heat conduction block comprises a heat conduction component and an insulation component; the heat conduction component has an approximately rectangular cross section and comprises a first side surface, a second side surface, a top surface and a bottom surface; the insulation component surrounds the heat conduction component on the outer periphery position of the heat conduction component, so that at least a part of the first side surface, the second side surface and the top surface of the heat conduction component is exposed out; the lower surface of the liquid cooling plate is in direct or indirect heat conduction contact with the top surface of the heat conduction component; in addition, cooling liquid can flow through the liquid cooling plate so as to cool the heat conduction component; the first side surface and the second side surface of the heat conduction component form surface contact with the inner surface of the first support arm and the inner surface of the second support arm of the tab connecting element.
