[0008] The water pipe and the spray pipe assembly are fixed in position in the main housing by means of a saddle pipe clamp. Specifically, the spray pipe assembly is fixed above the position where the wet curtain is installed inside the main housing by means of a saddle pipe clamp; the water pipe is fixed inside the main housing by means of a saddle pipe clamp.

[0009] As a preferred embodiment, the water level sensor and the ball float valve are respectively arranged on the left and right sides inside the main housing, and the water level sensor and the ball float valve are respectively connected to the control system. The pipeline connected to the ball float valve penetrates the main housing and cooperates with the external water supply system.

[0010] As a preferred embodiment, the wet curtain is fixed at the air inlet of the main housing by means of a wet curtain fixing assembly, and a wet curtain baffle is arranged at the air inlet of the main housing. The wet curtain baffle blocks the wet curtain and serves to limit the wet curtain.

[0011] As a preferred embodiment, the wet curtain fixing assembly includes two wet curtain fixing plates, which respectively fix the upper and lower ends of the wet curtain at the air inlet of the main housing.

[0012] As a preferred embodiment, the fan motor assembly includes a motor and a fan blade, the fan blade is fixed on the motor shaft head of the motor, and a motor support is arranged outside the motor. The motor is fixed at the central ventilation channel inside the main housing by means of the motor support, and the temperature sensor is fixed on the motor support.

[0013] As a preferred embodiment, the motor is an EC variable frequency motor.

[0014] As a preferred embodiment, the wet curtain is made of polyester synthetic fiber, and the internal gap adopts a 75° slope.

[0015] The air cooler mainly uses the principle of water evaporation to achieve air cooling. The detailed working principle is as follows, and the structure is as described above. The internal bottom side of the main housing serves as a water tank, so the internal bottom side of the main housing is referred to as a water tank below. The main housing serves to protect the internal components and guide the airflow; the motor is the power source for air flow; the wet curtain is the core cooling component, which is made of polyester synthetic fiber and has a large number of small pores; the submersible pump is used to deliver water in the water tank to the top of the wet curtain; and the water tank is used to store water for recycling.

[0016] Specific working process:

[0017] Air intake stage: the fan starts to work and draws hot air outside into the air cooler. At this time, the air temperature is relatively high, and the relative humidity may be low. For example, in a hot and dry environment, the air temperature may reach more than 30℃, and the relative humidity is about 30%-40%.

[0018] Water evaporation heat absorption stage: the submersible pump transports the water in the water tank to the top of the wet curtain, and the water flows evenly through the wet curtain under the action of gravity. Due to the water absorption and pore structure of the wet curtain material, a layer of water film is formed on the surface of the wet curtain.

[0019] Hot air passes through the wet curtain and contacts the water film on the surface of the wet curtain. In this process, the water changes from liquid to gas, that is, evaporation. According to the principle of physics, water evaporation needs to absorb heat, and these heat comes from the hot air passing through the wet curtain.

[0020] Cooling air delivery stage: the air cooled by the wet curtain is then blown to the space to be cooled through the air outlet under the action of the fan, so as to reduce the indoor temperature and improve the environmental comfort.

[0021] Water circulation process:

[0022] The water flowing down from the bottom of the wet curtain is collected in the water tank. In this way, the water can be recycled between the water tank and the wet curtain, reducing water waste. In the circulation process, in order to ensure the cleanliness of the water and the cooling effect, the submersible pump is also equipped with a filtering device around it to filter impurities in the water, and an appropriate amount of disinfectant can be added to prevent the growth of algae and bacteria.

[0023] The scheme adopts polyester synthetic fiber to make the wet curtain, which has good air purification effect, and better water absorption, durability and cooling effect.

[0024] The polyester synthetic fiber wet curtain can be woven into a fine mesh structure, and the diameter of the fiber is usually between several microns and tens of microns. This structure can effectively capture moisture and evenly distribute moisture when air flows. The internal gap is set at an angle of 75°. This angle setting can effectively remove various pollutants in the air, and the purified air meets the high standard air quality requirements, providing users with clean and healthy air environment, and effectively intercepting large particle impurities in outdoor or indoor air to prevent these impurities from entering the internal components of the air cooler, causing damage or blockage to subsequent components such as water pump, fan, etc.

[0025] The main machine shell is designed in a conical shape and is integrally formed by roll molding with a 20° taper angle. The air inlet is rectangular and the air outlet is round. The air inlet is larger than the air outlet, and the angle between the connecting line of the top surface of the main machine shell and the horizontal plane is 20°. This innovative structure can significantly improve its performance: from the principle of aerodynamics, the conical appearance enables the fan to guide and converge the airflow more effectively during operation.

[0026] In terms of air supply distance, when the fan starts, air is sucked in and gradually compressed and accelerated under the action of the conical structure, forming a strong and concentrated air flow beam, so that a higher wind speed and air volume can be maintained at a longer distance.

[0027] In terms of air volume, the conical design optimizes the air flow channel inside the fan, reducing air flow turbulence and energy loss. When air passes through the conical area, it can flow in a more orderly state, so that the fan can output more air volume under the same power input.

[0028] The internal structure of the fan adopts a symmetrical layout (here, relative symmetry, not absolute symmetry), with components symmetrically distributed on both sides. When the fan is running, the air flows on both sides cooperate with each other, avoiding the problem of air flow deviation caused by unilateral layout, ensuring uniform air pressure distribution in the entire air duct, thereby realizing uniform air flow and efficient delivery. Under this layout, the flow resistance of air in the cold air fan is relatively small, the working efficiency of the fan is improved, thereby improving the overall performance of the cold air fan, and by adjusting the speed of the fan and other methods, the air volume can be flexibly adjusted within a certain range, improving the overall performance of the cold air fan and meeting the needs of different working conditions.

[0029] The water level sensor is used to monitor the water level in real time. When the water level is low and the water volume needs to be replenished, the signal will be transmitted to the control system for water replenishment. The float ball valve controls water addition and automatically stops after reaching the water level.

[0030] Specifically, during the water inlet process, the float ball valve can automatically adjust the water inlet flow according to the water level rising speed and target water level. It can use an electric regulating valve to control the flow. If the water level rises quickly, it will automatically reduce the water inlet flow; if the water level rises slowly, it will appropriately increase the water inlet flow to achieve efficient and accurate water filling.

[0031] The temperature sensor monitors the temperature in real time and is in communication connection with the control system. After setting the temperature, the temperature sensor will continuously transmit signals to the control system, and the control system will control the operation of the cold air fan to achieve automatic temperature control.

[0032] In summary, the cold air fan has high air supply efficiency and good cooling effect, improves the overall performance of the cold air fan, and can automatically fill water and control temperature as needed, reducing manual operation and making it more convenient to use. It solves the technical problems of manual intervention, poor operation convenience, and other issues of traditional cold air fans. BRIEF DESCRIPTION OF DRAWINGS

[0045] The water pipe 7 and the spraying water pipe assembly 8 are positionally fixed in the main machine shell by a saddle-shaped pipe clamp 19. Specifically, the spraying water pipe assembly 8 is fixed above the position where the wet curtain 2 is installed in the inside of the main machine shell 1 by the saddle-shaped pipe clamp 19 (which can be seen from Figure 5 ); the water pipe 7 is fixed in the inside of the main machine shell by the saddle-shaped pipe clamp 19 (which can be seen from Figure 5 ).

[0050] The motor is an EC variable frequency speed regulation motor.

[0051] The wet curtain 2 is made of polyester synthetic fiber, and the internal gap adopts a 75° slope.

[0052] The air cooler mainly uses the water evaporation heat absorption principle to realize air cooling, and the following is the detailed working principle, and the structure is as above, wherein the internal bottom side part of the main machine shell 1 acts as a water tank, therefore, the internal bottom side part of the main machine shell 1 is simply referred to as a water tank below. The main machine shell 1 plays a role in protecting internal components and guiding airflow; the motor is a power source for promoting air flow; the wet curtain 2 is a core cooling component, which is made of polyester synthetic fiber and has a large number of tiny pores; the submersible pump 16 is used for conveying water in the water tank to the top of the wet curtain 2; and the water tank is used for storing water for recycling.

[0053] Specific working process:

[0054] Air entering stage: the fan starts to work to suck hot air outside into the air cooler. At this time, the air temperature is relatively high, and the relative humidity may be low, for example, in a hot and dry environment, the air temperature may be above 30℃, and the relative humidity is about 30%-40%.

[0055] Water evaporation heat absorption stage: the submersible pump 16 conveys water in the water tank to the top of the wet curtain 2, and the water uniformly flows through the wet curtain 2 under the action of gravity. Due to the water absorption and pore structure of the wet curtain 2 material, a layer of water film is formed on the surface of the wet curtain 2.

[0056] When the hot air passes through the wet curtain 2, it contacts the water film on the surface of the wet curtain 2. In this process, the water changes from liquid to gas, that is, evaporates. According to the principle of physics, water evaporation needs to absorb heat, and the heat comes from the hot air passing through the wet curtain 2. Each gram of water evaporation can absorb about 2.44 kilojoules of heat. For example, when the hot air temperature is 35℃, after passing through the wet curtain 2, due to the water evaporation heat absorption, the air temperature can be reduced to about 25℃, and the specific temperature reduction range depends on the initial temperature, humidity of the air and the water evaporation amount and other factors.

[0057] Cooling air sending stage: the air cooled by the wet curtain 2 is at a lower temperature, and then is blown to the space to be cooled, such as indoor, greenhouse, etc. by the fan through the air outlet 4, so as to reduce the indoor temperature and improve the environmental comfort.

[0058] Water circulation process:

[0059] The water flowing from the bottom of the wet curtain 2 is collected in the water tank. In this way, the water can be recycled between the water tank and the wet curtain 2, reducing the waste of water resources. In the circulation process, in order to ensure the cleanliness of the water and the cooling effect, the submersible pump 16 is also equipped with a filtering device around it to filter impurities in the water, and an appropriate amount of disinfectant can be added to prevent the growth of algae and bacteria.

[0060] The scheme adopts polyester synthetic fiber to make the wet curtain 2, which has good air purification effect, and better water absorption, durability and cooling effect.

[0061] The polyester synthetic fiber wet curtain 2 can be woven into a fine mesh structure, and the diameter of the fiber is usually between several microns and tens of microns. This structure can effectively capture moisture and evenly distribute moisture when the air flows. The internal gap adopts a 75° slope, which can effectively remove various pollutants in the air, and the purified air meets the high standard air quality requirements, such as PM2.5 removal rate of more than 99%, providing clean and healthy air environment for users, and effectively intercepting large particle impurities in outdoor or indoor air to prevent these impurities from entering the interior of the air cooler and causing damage or blockage to subsequent components (such as water pump, fan, etc.). The use of the wet curtain 2 greatly improves the water absorption and durability, prolongs the service life of the wet curtain 2, and enhances the cooling effect. In dry and hot areas, the cooling effect is more obvious, and the dry-bulb temperature at the outlet is 5-12℃ lower than the outdoor dry-bulb temperature, and in dry and hot areas, it can be about 15℃.

[0062] The main machine shell 1 is designed in a conical shape and is integrally formed by roll molding with a 20° taper. The air inlet 11 is rectangular, and the air outlet 4 is round. The air inlet 11 is larger than the air outlet 4, and the angle between the connecting line of the top surface of the main machine shell 1 and the horizontal plane is 20°. This innovative structure can significantly improve the performance of the air cooler. From the principle of aerodynamics, the conical appearance can more effectively guide and converge the airflow when the fan is running.

[0063] In terms of air sending distance, when the fan is started, the air is sucked in and gradually compressed and accelerated under the action of the conical structure, forming a strong and concentrated airflow beam, so that a higher wind speed and air volume can be maintained at a longer distance. Compared with the traditional non-conical design fan, the air sending distance can be effectively prolonged by 20%.

[0064] In terms of air volume, the conical design optimizes the airflow channel inside the fan, reducing airflow turbulence and energy loss. When air passes through the conical area, it can flow in a more orderly state, allowing the fan to output more air volume under the same power input. This unique conical design fundamentally improves the air supply efficiency of the fan assembly, laying a solid foundation for its wide application in various ventilation, air conditioning and industrial air supply fields.

[0065] The internal structure of the fan adopts a symmetrical layout (here, relative symmetry, not absolute symmetry), with components symmetrically distributed on both sides. When the fan is running, the airflow on both sides cooperates with each other, avoiding the problem of airflow deviation caused by unilateral layout, ensuring uniform air pressure distribution in the entire air duct, thereby achieving uniform air flow and efficient delivery. Under this layout, the air flow resistance inside the air cooler is relatively small, the working efficiency of the fan is improved, thereby improving the overall performance of the air cooler, and by adjusting the speed of the fan, the air volume can be flexibly adjusted within a certain range, improving the overall performance of the air cooler and meeting the needs of different working conditions.

[0066] The water level sensor is used to monitor the water level in real time. When the water level is low and the water quantity needs to be replenished, it will send a signal to the control system to replenish water. The float ball valve controls the water supply and automatically stops after reaching the water level.

[0067] Specifically, during the water inlet process, the float ball valve can automatically adjust the water inlet flow according to the water level rising speed and target water level. It can use an electric regulating valve to achieve flow control. If the water level rises quickly, it will automatically reduce the water inlet flow; if the water level rises slowly, it will appropriately increase the water inlet flow to achieve efficient and accurate water filling.

[0068] The temperature sensor monitors the temperature in real time and is in communication connection with the control system. After setting the temperature, the temperature sensor will continuously send signals to the control system, and the control system will control the operation of the air cooler to achieve automatic temperature control.

[0069] In summary, the air cooler has high air supply efficiency and good cooling effect, improves the overall performance of the air cooler, and can automatically fill water and control temperature as needed, reducing human operation and making it more convenient to use. It solves the technical problems of manual intervention, poor operation convenience of traditional air coolers in water filling and temperature control.

[0070] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. In addition, the technical solutions of various embodiments can be combined with each other, but must be based on the realization of ordinary technical personnel in the art; when the combination of technical solutions appears contradictory or unachievable, it shall be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the present application.
