The cold water preparation device comprises a water storage tank and a spiral coil heat exchange mechanism arranged in the water storage tank, and the spiral coil heat exchange mechanism comprises a cold source input header pipe, a cold source output header pipe and a plurality of spiral branch pipes connected between the cold source input header pipe and the cold source output header pipe in parallel. The spiral coil pipes of the multiple spiral branch pipes are the same in circle center and different in diameter. The spiral coil pipe heat exchange mechanism adopts ethylene glycol with the temperature ranging from-20 DEG C to-15 DEG C as a cold source. The device further comprises a temperature regulation and control mechanism. The spiral coil pipe heat exchange mechanism is arranged to be of a structure comprising a plurality of spiral branch pipes which are arranged in parallel, so that the heat exchange area can be increased, the length of the spiral coil pipe can be shortened, the flow resistance of a co
