[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] This embodiment provides a heat exchange device that can continuously reduce the water temperature to obtain ice water at a lower temperature. Figures 1 to 9As shown, the heat exchange device of this embodiment includes a heat exchanger assembly 1 and a vortex tube assembly 2. Wherein:

[0035] The heat exchanger assembly 1 comprises a heat exchanger outer tube 11 and a heat exchanger inner tube 12 sleeved on the inner side of the heat exchanger outer tube 11. The heat exchanger outer tube 11 comprises a cold air inlet 11a and a hot air outlet 11b. The heat exchanger inner tube 12 comprises a water inlet 12a and a water outlet 12b.

[0036] The vortex tube assembly 2 has a compressed air inlet end 2a, a cold air outlet end 2b and a hot air outlet end 2c, and the cold air outlet end 2b of the vortex tube assembly 2 is connected to the cold air inlet 11a of the heat exchanger outer tube 11;

[0037] Among them, the cold air inlet 11a of the heat exchanger outer tube 11 and the water outlet 12b of the heat exchanger inner tube 12 are arranged at the same end of the heat exchanger assembly 1, and the hot air outlet 11b of the heat exchanger outer tube 11 and the water inlet 12a of the heat exchanger inner tube 12 are arranged at the other end of the heat exchanger assembly 1.

[0038] In the heat exchange device of this embodiment, when compressed air enters the vortex tube assembly through the compressed air inlet end of the vortex tube assembly, the compressed air will flow in the vortex tube assembly in a high-speed rotating form and form cold air and hot air. The cold air enters the outer tube of the heat exchanger through the cold air outlet end of the vortex tube assembly and flows from the cold air inlet of the outer tube of the heat exchanger toward the hot air outlet. The water that needs to be cooled enters the inner tube of the heat exchanger from the water inlet of the inner tube of the heat exchanger and flows from the water inlet of the inner tube of the heat exchanger toward the water outlet. Since the cold air inlet of the outer tube of the heat exchanger and the water outlet of the inner tube of the heat exchanger are arranged at the same end of the heat exchanger assembly, and the hot air outlet of the outer tube of the heat exchanger and the water inlet of the inner tube of the heat exchanger are arranged at the other end of the heat exchanger assembly, the cold air flowing in the outer tube of the heat exchanger and the water flowing in the inner tube of the heat exchanger form opposite movements, so that the cold air in the outer tube of the heat exchanger continuously cools the water in the inner tube of the heat exchanger, thereby achieving the effect of continuously cooling the water to be cooled. As for the principle that the compressed air enters the vortex tube assembly through the compressed air inlet end to form cold air and hot air, it is common knowledge in the art and will not be elaborated here.

[0046] The conical plug 25 is sleeved in the cavity 210 of the vortex tube body 21 and is located at the second end of the vortex tube body 21; wherein the large end 25a of the conical plug 25 is close to the hot air outlet end 2c, and the small end 25b of the conical plug 25 is far away from the hot air outlet end 2c.

[0047] In order to enhance the sealing between the sleeve components in the vortex tube assembly to ensure the maximum output of the cold air and hot air formed in the vortex tube assembly, in this embodiment, the sleeve connection between the cold air sleeve 22 and the air inlet sleeve 23 is provided with a first sealing ring 261, the sleeve connection between the air inlet sleeve 23 and the first end of the vortex tube body 21 is provided with a second sealing ring 262, the sleeve connection between the second end of the vortex tube body 21 and the hot air sleeve 24 is provided with a third sealing ring 263, and the sleeve connection between the conical plug 25 and the second end of the vortex tube body 21 is provided with a fourth sealing ring 264.
