[0019] When the injection molding equipment starts to run and needs to be cooled, the water inlet pump 13 is started to draw the used cooling water, which may have been warmed up, from the water outlet of the injection molding equipment, and send it into the water tank 3 through the pipeline for storage; the water pump 4 draws the cooling water from the lower end of the water tank 3, and sends it to the mixer 7 through the first water outlet pipe 6; at the same time, according to the cooling requirement, the cooling liquid in the liquid storage tank 9 is sent into the mixer 7 through the first liquid discharge branch pipe 10, and the amount and type of the cooling liquid can be adjusted according to the specific cooling requirement of the injection molding equipment to achieve the best cooling effect; part of the cooling water (after being cooled by air cooling) in the air-cooled circulating water tower 2 also enters the mixer 7 through the second liquid discharge branch pipe 11 and the third water outlet pipe 12, and is mixed with the water from the water tank 3 and the liquid storage tank 9; in the mixer 7, the water of different sources and temperatures is fully mixed to form the required cooling water; the mixed cooling water flows back to the water tank 3 through the second water outlet pipe 8, forming a closed cooling water circulation system; when the temperature, flow or pressure of the cooling water in the water tank 3 reaches the preset condition, the water pump 14 is started to draw the cooling water from the water tank 3 and send it to the water inlet of the injection molding equipment through the pipeline to provide stable cooling water supply for the injection molding equipment; the control device is equipped with an industrial personal computer, which can monitor the cooling requirement of the injection molding equipment, the water temperature and water quantity in the water tank 3 and other parameters in real time; according to the monitored data, the intelligent control system automatically adjusts the working state of the water pump 4, the water inlet pump 13, the water pump 14 and the air-cooled circulating water tower 2, so that the operation of the cooling water circulation system is not only efficient but also energy-saving; when the injection molding equipment does not need to be cooled or is stopped, the intelligent control system can automatically turn off the related equipment to avoid invalid cooling and energy waste, and realizes efficient, stable and energy-saving cooling of the injection molding equipment.

[0020] Please refer to Figure 1 As an embodiment of the utility model, the cabinet body 1 side wall is provided with an industrial personal computer 15, wherein the industrial personal computer 15 is electrically connected with the air-cooled circulating water tower 2, the water pump 4, the water inlet pump 13 and the water pump 14 respectively.

[0021] In the above-mentioned scheme, the industrial personal computer is the core of the entire cooling water circulation control device, which can first monitor the working state of each component in the system in real time, including the heat dissipation efficiency of the air-cooled circulating water tower 2, the flow of the water pump 4, the pressure of the water inlet pump 13 and the water pump 14, and the water level and temperature in the water tank 3 and other key parameters; through the built-in sensor or the externally connected sensor network, the industrial personal computer can accurately collect these data to provide basic information for subsequent control decisions.

[0022] For example, when the injection molding equipment needs higher cooling efficiency, the industrial computer may increase the flow of the water pump 4, and adjust the rotating speed of the cooling fan 203 of the air-cooled circulating water tower 2, so as to ensure that the cooling water can quickly and effectively reduce the temperature; on the contrary, when the injection molding equipment has low load or is stopped, the industrial computer may reduce or stop the operation of the related pumps, so as to avoid unnecessary energy consumption.

[0023] The industrial computer realizes intelligent monitoring, control, fault diagnosis and remote management of the whole cooling water circulating control device through electrical connection with the air-cooled circulating water tower 2, the water pump 4, the water inlet pump 13 and the water outlet pump 14, and provides a strong guarantee for efficient, stable and energy-saving operation of the injection molding workshop.

[0024] Please refer to Figure 3 , Figure 4 , as an embodiment of the utility model, the air-cooled circulating water tower 2 includes two sets of condensers 201, wherein the two sets of condensers 201 are symmetrically arranged in the shape of "V"; the two sets of condensers 201 are fixedly connected with the cabinet 1 through the fixing frame 202, wherein the condenser 201 is provided with a cooling fan 203 above, and the cooling fan 203 is fixedly connected with the top end of the cabinet 1.

[0025] In the above-mentioned scheme, the core function of the air-cooled circulating water tower 2 is heat dissipation, and the two sets of condensers 201 symmetrically arranged in the shape of "V" are the key components to realize this function; after the cooling water absorbs heat from the injection molding equipment, it is sent into the condenser 201 of the air-cooled circulating water tower 2 through the pipeline; inside the condenser 201, the cooling water contacts the pipe wall of the condenser 201, transfers heat to the pipe wall, and the pipe wall further transfers heat to the surrounding air; due to the symmetric arrangement of the two sets of condensers 201 in the shape of "V", this design helps to increase the heat dissipation area and improve the heat dissipation efficiency, so that the cooling water can reduce the temperature faster; the cooling fan 203 is located above the condenser 201, and its main function is to accelerate the air flow around the condenser 201, thereby enhancing the heat dissipation effect; when the cooling fan 203 starts, it will suck in external air and blow it through the heat dissipation fins or pipelines of the condenser 201, accelerating the exchange and dissipation of heat; in this way, the cooling fan 203 can significantly reduce the temperature of the surface of the condenser 201, and thus the cooling water can be cooled more effectively; in the air-cooled circulating water tower 2, after the cooling water is cooled by the condenser 201, the temperature is reduced, and then the cooling water is returned to the injection molding equipment or other components that need to be cooled through the pipeline, forming a closed circulation; at the same time, the cooling fan 203 continuously works, continuously taking away heat from the condenser 201, and discharging it to the environment through air convection; this air-cooled circulating mode not only saves energy and protects the environment, but also can adjust the rotating speed of the cooling fan 203 and the number of the condensers 201 according to the needs, so as to meet the cooling requirements under different working conditions.

[0027] In the above scheme, the liquid storage tank 9 stores a proper amount of cooling liquid, which can be water, ethylene glycol or other fluid with suitable thermal physical properties; when the air-cooled circulating water tower 2 starts to work, the cooling liquid is sent into the inlet pipe 204 of the condenser 201 through the second liquid discharge branch pipe 11; here, the cooling liquid absorbs and carries away the heat transferred from the injection molding equipment or other heat sources; the cooling liquid flows inside the condenser 201 and exchanges heat with the pipe wall of the condenser 201, thereby reducing its own temperature; inside the condenser 201, the cooling liquid contacts the pipe wall and transfers heat to the pipe wall, and the pipe wall further transfers heat to the heat dissipation fins or pipes outside the condenser 201; at the same time, the heat dissipation fan 203 above the air-cooled circulating water tower 2 starts to work, accelerating the air flow around the condenser 201, thereby enhancing the heat dissipation effect; in this way, the heat in the cooling liquid is effectively dissipated to the environment, so that the temperature of the cooling liquid is further reduced; after heat dissipation in the condenser 201, the cooling liquid has a significantly reduced temperature, and at this time it flows out of the condenser 201 through the outlet pipe 205; the outlet pipe 205 is connected with the third outlet pipe 12, and the cooling liquid is sent into the mixer 7 through the third outlet pipe 12; in the mixer 7, the cooling liquid can be mixed with cooling water from the water tank 3 or other sources to adjust the temperature and flow of the mixed cooling water; the mixed cooling water is again sent into the injection molding equipment or other components that need to be cooled, forming a closed cycle; the inlet and outlet amounts of the condenser 201 can be intelligently controlled and adjusted by the industrial personal computer, according to the real-time cooling requirements of the injection molding equipment, the environmental temperature and the temperature of the surface of the condenser 201 and other parameters, the industrial personal computer can automatically adjust the inlet and outlet amounts of the condenser 201 to achieve the best heat dissipation effect and energy consumption ratio; at the same time, the industrial personal computer can also monitor the pressure, flow and other parameters inside the condenser 201 to ensure that the condenser 201 operates in a safe and stable condition.

[0028] Please refer to Figure 4 As an embodiment of the utility model, the heat dissipation fan 203 is arranged between the two groups of condensers 201, wherein the air inlet end of the heat dissipation fan 203 is provided with a plurality of heat exchange fins 16.

[0029] In the above scheme, the heat exchange sheet 16 is a heat exchange element located at the air inlet end of the heat dissipation fan 203, which mainly functions to increase the heat exchange area between the air and the condenser 201, thereby improving the heat dissipation efficiency; the heat exchange sheet 16 is usually made of a high-thermal-conductivity material, such as aluminum or copper, and has a plurality of small heat dissipation fins or channels to increase the contact area between the air and the condenser 201; when the air flows through the heat exchange sheet 16, heat is transferred from the condenser 201 to the air through the heat exchange sheet 16, and is carried away by the heat dissipation fan 203, thereby achieving effective heat dissipation.
