By adopting the heat exchange tube bundle 202, the contact area between the heat exchange tube bundle and the water fluid in the ice water tank 201 can be increased, and the heat exchange efficiency is improved, so that the water in the ice water tank 201 can be rapidly cooled to form flowing ice water. The heat exchange tube bundle 202 and the water in the ice water tank 201 are subjected to heat exchange and rapid water to form frozen water by circularly introducing a cold fluid refrigerant into the heat exchange tube bundle 202. Optionally, the flow direction of the cooling fluid in the heat exchange tube bundle 202 is opposite to the flow direction of the water fluid to be chilled in the ice water tank 201, so that sufficient contact and heat exchange are realized, and the water fluid to be chilled is rapidly cooled.
