[0024] In order to deepen the understanding of the present utility model, the following will further describe the present utility model in detail in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model. Embodiment 1

[0025] According to Figure 1 、 2 As shown in 3 and 4, this embodiment proposes an economic industrial cooling fan water defrosting structure, including an external housing 1 and fins 2. The fins 2 are arranged inside the external housing 1, and multiple groups of fins 2 are arranged at equal intervals. Multiple groups of heat exchange tubes 3 are connected between the multiple groups of fins 2, and multiple groups of heat exchange tubes 3 are arranged in a staggered pattern, and the distance between adjacent two groups of heat exchange tubes 3 is 36 - 40x30 - 35 mm;

[0026] One side of the top of the external housing 1 is provided with a defrosting water tray 4, and a water outlet is provided at the bottom of the defrosting water tray 4. The water outlet is communicated to the inside of the external housing 1, and the water outlet faces the heat exchange tubes 3 and the fins 2. A water inlet pipe 5 is provided at the middle position on one side of the defrosting water tray 4. During use, the defrosting water flows in from the water inlet pipe 5 of the defrosting water tray 4, flows out from the bottom of the defrosting water tray 4, and flows onto the heat exchange tubes 3 and the fins 2 to achieve the defrosting function. The multiple groups of heat exchange tubes 3 are arranged in a staggered row, and the distribution method is more compact, increasing the blockage of the defrosting water flow during the water defrosting process and greatly alleviating the water splashing phenomenon during the defrosting process.

[0027] The specification of the heat exchange tube 3 is φ12x0.32 - 0.18mm, and the heat exchange tube 3 is an internally threaded tube. Without changing the heat exchange area of the air cooler, optimizing the staggered row spacing of the heat exchange tubes 5 to 36 - 40x30 - 35mm is beneficial to reducing the required space size of the fins 2. The specification of the heat exchange tube 5 is changed to an internally threaded tube of φ12x0.32 - 0.18mm. On the basis of ensuring the same heat exchange effect, the size of the heat exchange tube 5 is reduced, the overall structural size is reduced, which is convenient for installation, transportation and maintenance, and the cost is reduced without changing the heat exchange effect.

[0028] One end of the external housing 1 is provided with a heat exchange cavity 6. One end of the heat exchange tube 3 is communicated with the heat exchange cavity 6. Both the upper and lower ends on one side of the heat exchange cavity 6 are connected with connecting pipes 7. The heat exchange cavity 6 is connected to the heat exchange liquid through the connecting pipes 7. The heat exchange liquid enters the heat exchange tubes 3, is discharged after heat exchange, and circulates.

[0029] One side of the external housing 1 is provided with a fan 8, and multiple groups of fans 8 are provided. The input end of the fan 8 faces the space between two adjacent groups of fins 2. The heat exchange tubes 3 exchange heat with the external air through the effect of the internal heat exchange liquid, so that the fan 8 blows out cold air.

[0030] Both ends of the defrosting water tray 4 are sleeved with hoop pieces 9, and support feet are provided on both sides of the hoop pieces 9. The support feet are fixed to the external housing 1 through bolts 10. During use, the defrosting water tray 4 is installed on the top of the external housing 1 and fixed to the external housing 1 through the hoop pieces 9 in cooperation with the bolts 10.

[0031] Multiple groups of the heat exchange tubes 3 are connected to one side of the fins 2, and the other side of the fins 2 is a closed surface. Without changing the heat exchange area of the air cooler, optimizing the staggered row spacing of the heat exchange tubes 5 to 36 - 40x30 - 35mm is beneficial to reducing the required space size of the fins 2. Embodiment 2

[0032] According to Figure 1 、 2, as shown in Figures 3 and 4, this embodiment proposes an economic industrial air cooler water defrosting structure, including an external housing 1 and fins 2. The fins 2 are arranged inside the external housing 1, and multiple groups of fins 2 are equidistantly arranged. A heat exchange tube 3 is connected between multiple groups of fins 2, and multiple groups of heat exchange tubes 3 are arranged in a staggered pattern. The distance between adjacent two groups of heat exchange tubes 3 is 36 - 40 x 30 - 35 mm;

[0033] On one side of the top of the external housing 1, there is a defrosting water tray 4, and a water outlet is provided at the bottom of the defrosting water tray 4. The water outlet communicates with the inside of the external housing 1 and faces the heat exchange tube 3 and the fins 2. At the middle position on one side of the defrosting water tray 4, there is a water inlet pipe 5. During use, the defrosting water flows in from the water inlet pipe 5 of the defrosting water tray 4, flows out from the bottom of the defrosting water tray 4, and flows onto the heat exchange tube 3 and the fins 2 to achieve the defrosting function. Multiple groups of heat exchange tubes 3 are arranged in a staggered pattern, and the distribution method is more compact, increasing the blockage of the defrosting water flow during the water defrosting process and greatly alleviating the splashing phenomenon during the defrosting process.

[0034] The specification of the heat exchange tube 3 is φ12x0.32 - 0.18 mm, and the heat exchange tube 3 is an internally threaded tube. Without changing the heat exchange area of the air cooler, optimizing the staggered spacing of the heat exchange tube 5 to 36 - 40 x 30 - 35 mm is beneficial to reducing the required space size of the fins 2. Changing the specification of the heat exchange tube 5 to an internally threaded tube with φ12x0.32 - 0.18 mm reduces the size of the heat exchange tube 5 on the basis of ensuring the same heat exchange effect, reducing the overall structural size, facilitating installation, transportation, and maintenance, and reducing the cost without changing the heat exchange effect.

[0035] At the bottom of the external housing 1, there is a water leakage channel 11, and the water leakage channel 11 is connected to a recovery water tank. During use, the defrosting water flows in from the water inlet pipe 5 of the defrosting water tray 4, flows out from the bottom of the defrosting water tray 4, and flows onto the heat exchange tube 3 and the fins 2 to achieve the defrosting function. The defrosting water flows to the water leakage channel 11 and enters the recovery water tank for recycling and reuse.

[0036] The water defrosting structure of this economical industrial air cooler allows the defrosting water to flow in through the water inlet pipe 5 of the defrosting water tray 4, flow out from the bottom of the defrosting water tray 4, and flow onto the heat exchange tubes 3 and the fins 2 to achieve the defrosting function. Multiple groups of heat exchange tubes 3 are arranged in a staggered pattern, with a more compact distribution method, which increases the blockage of the defrosting water flow during the water defrosting process and greatly alleviates the water splashing phenomenon during defrosting. Moreover, in the case of the same heat exchange area of the air cooler, the staggered spacing of the heat exchange tubes 5 is optimized to 36 - 40x30 - 35 mm, which is beneficial to reducing the required space size of the fins 2. The specification of the heat exchange tubes 5 is changed to an internal thread tube with a diameter of φ12x0.32 - 0.18 mm. On the basis of ensuring the same heat exchange effect, the size of the heat exchange tubes 5 is reduced, the overall structural size is reduced, facilitating installation, transportation and maintenance, and the cost is reduced under the condition of the same heat exchange effect.
