Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology, specifically relating to an intelligent composite air-cooling device. Background Technology

[0002] A hybrid air cooler is a high-efficiency heat exchange device that combines dry air cooling with auxiliary evaporative cooling technology. It is specifically designed for cooling media (such as refrigerants, lubricating oils, and process gases) in air conditioning systems, data centers, or industrial processes. Currently, existing hybrid air coolers can basically meet the needs of media cooling, but they still have certain shortcomings in actual operation: On the one hand, the level of intelligence of existing hybrid air coolers is low, and they still rely on manual judgment and operation during operation. For example, the switching of their operating modes depends on manual judgment or the setting of fixed thresholds, and they cannot dynamically adapt to complex changes in operating conditions. The adjustment of some key parameters (such as fan speed and spray volume) is lagging and requires manual adjustment based on experience. On the other hand, traditional composite air coolers only have a single air source at the bottom of the unit. After exchanging heat with the evaporative cooling tubes below, the temperature of the outside air rises. After passing through the finned tubes above, the temperature difference between the outside air and the medium inside the finned tubes is small, affecting the heat exchange capacity of the air-cooling section. Furthermore, because the outside air is simultaneously cooled by spraying as it enters the evaporation section, humid and hot air forms inside the unit. This humid and hot air comes into contact with the cold outside air as it is discharged, forming water mist, and even icing in winter, affecting the safe operation and stability of the equipment. Additionally, the poor heat exchange caused by humid and hot air also leads to high water consumption in the evaporation section, resulting in poor water-saving capabilities. Utility Model Content

[0003] This invention provides an intelligent composite air-cooling device to solve the problems mentioned in the background art, such as low level of intelligence, poor heat exchange performance, easy formation of water mist or ice, and high water consumption in existing composite air coolers.

[0004] The technical solution adopted by this utility model is: an intelligent composite air-cooling device, including an outer shell, inside which a fan, a dry air-cooling unit, a water collection device, a spray pipe, an evaporative cooling unit and a circulating water tank are arranged sequentially from top to bottom. The dry air-cooling unit and the evaporative cooling unit are interconnected. The working medium can pass through the dry air-cooling unit and the evaporative cooling unit in sequence and then be discharged outward. A medium discharge pipe connected to the evaporative cooling unit is installed on the outer shell, and a temperature transmitter for detecting the temperature of the discharged working medium is installed on the medium discharge pipe.

[0005] Several motorized louvers are installed on the side wall of the outer casing. The motorized louvers are located between the circulating water tank and the evaporative cooling unit, and between the dry air cooling unit and the water collection device.

[0006] A fresh air duct is formed inside the outer casing and between the dry air-cooled unit and the water collection device. The fresh air duct is connected to the external space of the outer casing through motorized louvers.

[0007] The spray pipe is horizontally arranged inside the outer casing. Spray nozzles are evenly installed on the lower part of the pipe wall. One end of the spray pipe passes through the side wall of the outer casing and is connected to a pipe. The pipe is connected to the circulating water tank. A water pump motor is installed on the pipe. The liquid entering the spray pipe from the circulating water tank can be sprayed out from the spray nozzles and sprayed towards the evaporative cooling unit.

[0008] A medium inlet pipe is installed on the upper part of the outer wall of the outer casing, and the medium inlet pipe is connected to the dry air cooling unit.

[0009] The fan is equipped with a vibration transmitter.

[0010] The dry air-cooling unit is a finned tube air cooler.

[0011] The system also includes a control module, which is electrically connected to the fan, vibration transmitter, temperature transmitter, electric louver, and water pump motor, respectively.

[0012] The vibration transmitter is used to collect the vibration status of the fan, and the temperature transmitter is used to collect the temperature data of the working medium after cooling. The vibration status data and temperature data are transmitted to the control module, which controls the fan speed, the opening and closing size of the electric louvers, and the speed of the water pump motor.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model has a reasonable design structure. By setting up a fresh air channel between the dry air-cooling unit and the water collection device, outside air can enter the fresh air channel through the electric louvers. This allows the newly introduced cold air to mix with the humid and hot air passing through the water collection device, thereby achieving the purpose of cooling. This increases the original logarithmic temperature difference of the air-cooling section, enhances the cooling function of the air-cooling section, and at the same time reduces the total heat load of the evaporation section, reduces the water consumption of the evaporation section, and reduces the total amount of water vapor entering the air-cooling section.

[0015] This invention allows cold and hot air to mix quickly and reach the dew point through a fresh air duct. Water vapor condenses into mist in advance inside the equipment, forming water droplets that fall into the water tank for recycling, thus further saving water and reducing the total moisture content of the air entering the fin segment.

[0016] This invention reduces the water vapor content inside the equipment, resulting in a significant decrease in the humidity of the air discharged outwards. After being discharged from the equipment, the problem of cold air condensing, fogging, or even freezing will no longer occur, which is beneficial to the safety and stability of the equipment operation.

[0017] This invention features a vibration transmitter installed on the fan and a temperature transmitter installed at the medium outlet pipe. This allows for real-time monitoring and data collection of fan operation and medium cooling status. Furthermore, the control module adjusts the air intake and spray volume of the electric louvers in real time, effectively improving the heat exchange effect and efficiency of the composite air-cooling device. This reduces manual workload, shortens the control cycle, and helps maintain good heat dissipation regulation, thereby achieving energy conservation and emission reduction.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As shown in the figure, an intelligent composite air-cooling device includes an outer shell 1. Inside the outer shell 1, from top to bottom, are arranged a fan 2, a dry air-cooling unit 3, a water collection device 4, a spray pipe 5, an evaporative cooling unit 7, and a circulating water tank 8. The dry air-cooling unit 3 and the evaporative cooling unit 7 are interconnected. The water collection device 4 is also a water remover or moisture separator, used to efficiently separate liquid water droplets in the air, preventing moisture from being carried by the airflow to subsequent equipment, thereby reducing corrosion, scaling, and efficiency loss.

[0024] In this example, a medium inlet pipe 9 is installed on the upper part of the outer wall of the outer casing 1. The medium inlet pipe 9 is connected to the dry air-cooling unit 3. Specifically, the medium inlet pipe 9 is connected to the input end of the dry air-cooling unit 3. The working medium can enter the dry air-cooling unit 3 and achieve heat exchange by the fan 2 to achieve the air-cooling effect of the medium. The output end of the dry air-cooling unit 3 is connected to a connecting pipe 14. The connecting pipe 14 is located outside the outer casing 1, and its end is connected to the input port of the evaporative cooling unit 7, so that the working medium can flow out of the dry air-cooling unit 3 and then enter the evaporative cooling unit 7 for further cooling.

[0025] The working medium can pass through the dry air cooling unit 3 and the evaporative cooling unit 7 in sequence and then be discharged outward. A medium discharge pipe 11 connected to the evaporative cooling unit 7 is installed on the outer casing 1. A temperature transmitter 12 is installed on the medium discharge pipe 11 to detect the temperature of the discharged working medium. The temperature transmitter 12 is used to monitor the real-time temperature of the cooled working medium and feed the data back to the control module.

[0026] Several motorized louvers 10 are installed on the side wall of the outer casing 1. The motorized louvers 10 are located between the circulating water tank 8 and the evaporative cooling unit 7, and between the dry air cooling unit 3 and the water collection device 4. The motorized louvers 10 use a motor to control the opening and closing of the louvers. Their structure and principle are conventional methods in the existing technology and will not be described in detail here.

[0027] The motorized louvers 10 are divided into upper and lower groups. The upper motorized louvers 10 are located on the side wall of the outer casing 1 between the dry air-cooling unit 3 and the water collection device 4. A fresh air channel is formed inside the outer casing 1 between the dry air-cooling unit 3 and the water collection device 4. The fresh air channel is connected to the external space of the outer casing 1 through the motorized louvers 10. The air introduced from the upper motorized louvers 10 can enter the fresh air channel to come into contact with the humid and cold air below, so that the water vapor in the outer casing 1 will condense into fog in advance, thereby reducing the water content of the working section of the dry air-cooling unit 3. This can not only avoid the problem of water fog or ice formation of the air being discharged, but also allow the fog to turn into water droplets and flow into the circulating water tank 8, thus achieving a water-saving effect.

[0028] The spray pipe 5 is horizontally arranged inside the outer casing 1. Spray nozzles 6 are evenly installed on the lower part of the pipe wall. One end of the spray pipe 5 passes through the side wall of the outer casing 1 and is connected to a pipe. The pipe is connected to the circulating water tank 8. A water pump motor is installed on the pipe. The liquid entering the spray pipe 5 from the circulating water tank 8 can be sprayed out from the spray nozzles 6 and sprayed towards the evaporative cooling unit 7. Using the water pump motor as a power source, the liquid in the circulating water tank 8 is pumped into the spray pipe 5 and then sprayed out from the spray nozzles 6. The sprayed cold water comes into contact with the evaporative cooling unit 7 to achieve the purpose of heat exchange and further achieve the cooling effect of the working medium.

[0029] The fan 2 is equipped with a vibration transmitter 13. The fan 2 mainly includes a variable frequency motor, an impeller, and a support. The support is connected to the top of the outer casing 1. The working axis of the motor is perpendicular to the horizontal plane. The motor drives the impeller to rotate, thereby expelling the air inside the outer casing 1 upward. That is, the air is induced to flow from bottom to top by means of induced draft. The structure and working principle of the fan 2 are conventional settings in the existing technology and will not be described in detail here. The vibration transmitter 13 is mainly installed on the support of the fan 2 and is used to monitor the vibration frequency of the fan 2 in real time, thereby determining the speed of the fan 2, and then feeding the data back to the control module.

[0030] The dry air-cooling unit 3 is a finned tube air cooler, which adopts a structure of base tube with external fins, which can effectively dissipate heat and achieve heat exchange by contacting air; in addition, the main structure of the evaporative cooling unit 7 is a coil structure, in which the working medium flows. The liquid (usually water) is sprayed onto the surface of the coil by spraying. During the evaporation process of the liquid, a large amount of heat is absorbed, which can reduce the temperature of the working medium.

[0031] The system also includes a control module, which is electrically connected to the fan 2, vibration transmitter 13, temperature transmitter 12, electric louver 10, and water pump motor, respectively.

[0032] The vibration transmitter 13 is used to collect the vibration status of the fan 2, and the temperature transmitter 12 is used to collect the temperature data of the working medium after cooling. The vibration status data and temperature data are transmitted to the control module, which controls the speed of the fan 2, the opening and closing size of the electric louver 10, and the speed of the water pump motor.

[0033] Specifically, the control module is mainly a programmable logic controller (PLC), primarily used to collect real-time data from the vibration transmitter 13 and temperature transmitter 12, and to perform in-depth analysis and processing of this data using built-in algorithms and models. In addition, it includes a human-machine interface (HMI), which connects to the PLC controller and allows for the input of operating parameters or commands, enabling human-machine interaction. Through the PLC's built-in program, the opening degree of the motorized louvers 10 can be automatically adjusted according to environmental changes, operating modes, and load variations to control the airflow, thereby achieving intelligent control.

[0034] The working process of this composite air-cooling device is as follows: the fan 2 is started, and the electric louvers 10 located on the upper and lower sides of the outer shell 1 are opened, allowing outside air to enter the interior of the outer shell 1 through the electric louvers 10. At the same time, the water pump motor is started, causing water to enter the spray pipe 5 and spray out from the nozzle 6. The working medium flows in the coil of the evaporative cooling unit 7. The water contacts the coil and carries away heat through evaporation. This hot and humid air is first treated by the water collection device 4 to remove water, and then enters the fresh air duct. At this time, the cold air entering the fresh air duct from the upper electric louvers 10 comes into full contact with the hot and humid air. After the cold and hot air mix, they quickly reach the dew point, causing water vapor to condense into mist in advance inside the outer shell 1. After forming water droplets inside the equipment, they fall into the water tank for recycling. The air continues to flow upward and comes into contact with the dry air-cooling unit 3 to achieve heat exchange, and finally is discharged from the top of the outer shell 1. During this operation, the control module can monitor the vibration of the fan 2 and the temperature change of the working medium in real time. Based on the built-in program and instructions, it can adjust the speed of the fan 2, the water supply of the water pump motor (adjusting the spray volume), and the opening and closing of the electric louvers in real time, thereby achieving the effect of intelligent control. It has the advantages of energy saving, emission reduction, and reduced manual workload.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
