In the ice slurry generating heat exchange device, cold water with the temperature of 1-3 ℃ in the water inlet pipe 51 enters the barrel 10 through the first inlet and then enters the heat exchange pipe 30, meanwhile, secondary refrigerant with the temperature of-4-8 ℃ enters the chamber through the secondary refrigerant inlet 11, and the secondary refrigerant contacts the outer side wall of the heat exchange pipe 30 to reduce the temperature of the heat exchange pipe 30. Therefore, cold water in the heat exchange tube 30 gradually releases heat and condenses after contacting the inner side wall of the heat exchange tube 30, and water is formed into ice crystals on the inner surface of the heat exchange tube 30 to cover the inner side wall of the heat exchange tube 30. Compressed air in the compressed air pipe 52 is introduced into the barrel 10 through the second inlet and then enters the heat exchange pipe 30, the phenomena of vortex and cavity are formed on the inner side wall surface of the heat exchange pipe 30, ice particles formed on the inner side wall surface of the heat exchange pipe 30 are torn, the formation of an ice layer is avoided, heat transfer resistance is increased, the formation of the ice layer is avoided from blocking the inner wall of the heat exchange pipe 30, and the heat exchange efficiency is improved; on the other hand, after cold water is changed into supercooled water, air exists in the form of bubbles in the water flow, the supercooled water is promoted to be changed into ice crystal nuclei, and then the supercooled water enters an ice slurry collector along with an ice-water mixture.
