The present invention relates to a vortex bubble removing and cooling system for the electromagnetic shock wave generator in the lithotripter. The vortex bubble-removing and cooling system comprises a water-full cushion (17), a metal diaphragm (14) installed inside the chamber body (27) of the water cushion (17) and a coil (13) which is installed at the backside of the metal diaphragm (14). There is at least one first water nozzle (22) on the side wall of the chamber body (27) and a water suction tube (23) at the center of the chamber body (27). The first water nozzle (22) and the water suction tube (23) form a vortex-generating device. The vortex generated inside the chamber body will scour the surface of the metal diaphragm continuously so as to cool the heat and remove the air bubble. This will make the metal diaphragm be in good working condition and greatly increase the working life of the metal diaphragm and the coil.
