[0014] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] like Figure 1 As shown, the spiral evaporation fan includes a machine box 1, a water tank 2 and a refrigeration box 3 are installed in the machine box 1, the water tank 2 is located below the refrigeration box 3, the top of the water tank 2 is connected to the bottom of the refrigeration box 3 through a connecting pipe 4, the water tank 2 is filled with water, the water tank 2 is installed with an air pipe 5, the air pipe 5 is spirally arranged, the air pipe 5 successively extends out of the water tank 2 and the machine box 1 and is connected to a fan 6, the refrigeration coil 7 is installed in the refrigeration box 3, the refrigeration coil 7 is spirally arranged, the two ends of the refrigeration coil 7 extend out of the refrigeration box 3 and the machine box 1 respectively, the refrigeration coil 7 is filled with a coolant, the two ends of the refrigeration coil 7 are connected to a coolant supply device 8, the upper end of the refrigeration box 3 is connected with an air outlet pipe 9, and the air outlet pipe 9 extends out of the machine box 1. The coolant supply device 8 provides the coolant to the refrigeration coil 7. The fan 6 extracts the hot air in the space that needs to be cooled to form a hot air flow and fills it into the air pipe 5. The hot air flows out of the air pipe 5 and enters the water tank 2. After the water in the water tank 2 is initially cooled, it enters the refrigeration box 3. The heat in the hot air flow exchanges heat with the refrigerant in the refrigeration coil 7, thereby reducing the temperature to form a cold air flow. The cold air flow flows into the space that needs to be cooled after passing through the air outlet pipe 9. The refrigeration coil 7 is spirally arranged so that the hot air flow can fully exchange heat with the refrigerant during the rising and diffusion process.

[0018] Further, the water tank 2 includes a water tank conical section 10 located at the upper part of the water tank 2 and a water tank equal diameter section 11 located at the lower part of the water tank 2, the diameter of the upper end of the water tank conical section 10 is smaller than the diameter of the lower end of the water tank conical section 10, the refrigeration box 3 includes a refrigeration box conical section 12 located at the lower part of the refrigeration box 3 and a refrigeration box equal diameter section 13 located at the upper part of the refrigeration box 3, the diameter of the upper end of the refrigeration box conical section 12 is larger than the diameter of the lower end of the refrigeration box conical section 12, the lower end of the connecting pipe 4 is connected to the upper end of the water tank conical section 10, and the upper end of the connecting pipe 4 is connected to the lower end of the refrigeration box conical section 12. The air pipe 5 is located in the water tank conical section 10, and the refrigeration coil 7 is located in the refrigeration box conical section 12. The conical section 10 of the water tank, the connecting pipe 4, and the conical section 12 of the refrigeration box form a structure similar to a venturi tube. The cross-sectional area of ​​the hot air flow in the water tank 2 gradually decreases in the forward direction, the air pressure increases, and the hot air flow is refracted, which increases the residence time of the hot air flow in the water and improves the initial cooling effect. The cross-sectional area of ​​the hot air flow in the refrigeration box 3 gradually expands, and the flow rate of the hot air flow gradually decreases. In addition to the upward direction, the hot air flow also has a lateral diffusion speed. With the spiral setting of the refrigeration coil 7, the heat exchange time with the refrigerant is extended, and the heat exchange direction is more three-dimensional and comprehensive, which improves the heat exchange effect between the hot air flow and the coolant.

[0019] Furthermore, the refrigeration coil 7 includes a downward spiral section 14 and an upward spiral section 15 that are interconnected, and the downward spiral section 14 and the upward spiral section 15 are arranged alternately. The lower spiral section 14 and the upward spiral section 15 form a temperature gradient of spiral descent and then spiral ascent in the refrigeration box conical section 12 of the refrigeration box. The lower spiral section 14 and the upward spiral section 15 are arranged alternately, and from the overall point of view, the refrigeration box conical section 12 has a smaller temperature gradient in both the vertical direction and the planar direction, thereby improving the stability of the heat exchange between the refrigerant and the hot air and avoiding the poor heat exchange efficiency due to high local temperature.

[0020] Furthermore, the diameter of the downward spiral section 14 gradually decreases from top to bottom, and the diameter of the upward spiral section 15 gradually increases from bottom to top.

[0021] Furthermore, the lower end of the air pipe 5 extends out of the water tank 2 and the chassis 1 and is connected to the fan 6, and the upper end of the air pipe 5 spirals upward to form a tracheal spiral body, and the upper end diameter of the tracheal spiral body is smaller than the lower end diameter of the tracheal spiral body.

[0022] Furthermore, the upper end of the trachea 5 is sealed, and a plurality of air holes are distributed around the trachea 5. The hot air flows out from the air holes around the tracheal spiral body, and the hot air is divided into small bubbles, which increases the contact area between the hot air flow and the water. The tracheal spiral body makes the bubbles evenly distributed in the water tank 2.

[0023] Furthermore, the density of the pores gradually decreases from the lower end of the air pipe 5 to the upper end of the air pipe, thereby further improving the contact effect between the hot air flow and the water.

[0024] Further, the upper end of the water tank 2 is connected to a water inlet pipe 16, and the lower end of the water tank 2 is connected to a water outlet pipe 17, and the water inlet pipe 16 and the water outlet pipe 17 extend out of the chassis 1 and are respectively provided with valves. The water in the water tank can be replaced through the water inlet pipe 16 and the water outlet pipe 17.

[0025] Furthermore, the air outlet pipe 9 is connected to an air outlet cover 18 after extending out of the chassis.

[0026] The air pipe 5 and the refrigeration coil 7 are preferably made of a material with good thermal conductivity, such as a copper pipe.

[0027] It is worth mentioning that the technical features such as the refrigerant supply device, fan, refrigerant, etc. involved in the patent application of the present invention should be regarded as the prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the inventive point of the patent of the present invention.

It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present invention without creative work.
