Description

Technical Field

[0001] The present invention belongs to the technical field of heat exchange units, and in particular relates to an intelligent heat exchange unit. Background Art

[0002] A heat exchanger is a complete set of equipment that transfers heat from a primary heat network to a secondary heat network to meet users' demand for thermal energy such as hot water or steam. It is widely used in centralized heating, refrigeration, industrial waste heat recovery and other fields. In the field of liquid metals, including the production and processing of liquid non-ferrous metals, liquid precious metals and liquid rare earth metals, intelligent heat exchangers also play an indispensable role. For example, in the smelting of liquid non-ferrous metals, precise temperature control is required to ensure the purity and quality of the metal; the refining process of liquid precious metals has extremely high requirements for temperature stability and control accuracy; the processing of liquid rare earth metals not only requires ensuring that the temperature meets the process requirements, but also requires ensuring the stable operation of the entire system to avoid affecting the metal properties. The many functions of intelligent heat exchangers can just meet these strict requirements.

[0003] The control cabinet is crucial to the intelligent operation of the intelligent heat exchanger unit. It is the "brain" of the intelligent heat exchanger unit and has many aspects of importance and influence on its overall performance and intelligent operation effect. The control cabinet integrates various control functions of the intelligent heat exchanger unit and is the control center of the entire system. It can centrally control various equipment such as circulation pumps, water supply pumps, electric regulating valves, coordinate the operation of various equipment, ensure the overall stable operation of the intelligent heat exchanger unit, and achieve efficient heat transfer and distribution. It can collect and process data from sensors in various parts of the intelligent heat exchanger unit in real time, such as temperature, pressure, flow and other parameters. Through the analysis and calculation of these data, the control cabinet can accurately judge the operating status of the system and provide information for subsequent control decisions. The intelligent heat exchanger provides a basis for policy, so that the intelligent heat exchanger unit can be accurately adjusted according to actual needs. When the intelligent heat exchanger unit is in operation, the processing components in the control cabinet will be in operation at the same time and generate heat. Therefore, the control cabinet is currently equipped with a cooling fan to assist in heat dissipation to avoid the problem that the temperature in the control cabinet is too high, which may cause the performance of the electronic components to drift, thereby affecting the accuracy of the control signal. However, the wind direction of the fixedly installed cooling fan is relatively fixed, and it can only form airflow in a limited area, making it difficult to fully cover every corner and all control components in the control cabinet. There will be dead corners in the control cabinet, making it impossible for the control components located in these areas to be fully cooled, thereby having a significant impact on the operating stability and energy-saving effect of the entire heat dissipation unit.

[0040] The PLC controller is fixedly arranged on the inner wall of the control cabinet 8 and is electrically connected with the multi-region auxiliary heat dissipation mechanism 2 and the electric control element use quality synchronous detection feedback mechanism 4.

[0041] The operating principle of the present invention is described as follows: when the unit body 7 and the control cabinet 8 are running (the control cabinet 8 collects and processes data from sensors at various parts of the unit body 7 in real time, such as temperature, pressure, flow and other parameters. By analyzing and calculating these data, the control cabinet 8 accurately judges the operating status of the system, provides a basis for subsequent control decisions, and enables the unit body 7 to be accurately adjusted according to actual needs), the PLC controller controls the multi-zone auxiliary heat dissipation mechanism 2 to work synchronously, and the vertical electric slide rail 21 and the horizontal electric slide rail 22 cooperate to move the air spray head 24 and the air exhaust head 25 to the position of the electric control component that needs heat dissipation in turn. After moving into place, the infrared temperature sensor 26 detects the heating temperature of the electric control component, and the PLC controller controls The blower 29 and the exhaust fan 210 are working, and the blower 29 cooperates with the air nozzle 27 and the air nozzle head 24 to blow air to the electronic control components, and the exhaust fan 210 cooperates with the exhaust pipe 28 and the exhaust head 25 to exhaust air to the electronic control components, thereby quickly transferring the heat generated by the electronic control components to avoid the problem of heat accumulation affecting the working stability of the electronic control components. The higher the temperature detection value of the electronic control components by the infrared temperature sensor 26 is, the higher the working power of the blower 29 and the exhaust fan 210 is controlled by the PLC controller, thereby increasing the stronger heat dissipation airflow to achieve more efficient heat dissipation. Through the driving action of the vertical electric slide 21 and the horizontal electric slide 22, the air nozzle head 24 and the exhaust head 25 are moved to each electronic control component in turn for auxiliary heat dissipation, and the work is circulated continuously.

[0042] The air ejected by the air jet head 24 can blow away the dust and impurities accumulated on the electronic control components, and quickly take away these dust and impurities through the exhaust head 25, so as to avoid the accumulation of dust and impurities on the electronic control components, which may cause poor contact and affect the heat dissipation and electrical performance. The sucked dust and impurities enter the filter housing 31, and are effectively filtered and intercepted by the filter screen 32 installed in the filter housing 31, waiting for subsequent cleaning. The dust and impurities can be directly cleaned and removed by the heat dissipation equipment, which saves costs, is easy to operate, and is more efficient. The cleaning of the filter screen 32 can be handled by removing the cleaning end cover 33.

[0043] The vertical electric slide 21 and the horizontal electric slide 22 drive the air spray head 24 and the exhaust head 25 to move cyclically to the positions of the electric control components according to the preset program, and stay for 3 seconds each time. During each movement process, the PLC controller will control the servo motor 44 to work for 5 seconds. The servo motor 44 drives the synchronous screw 43 to rotate. The threaded connection between the synchronous screw 43 and the moving seat 45 enables the moving seat 45 to drive the trigger feedback mechanism 5 to move to the corresponding detection plate 42. The distance between each detection plate 42 and the trigger feedback mechanism 5 depends on the normal heating temperature of the electric control component at the corresponding position during normal operation. The higher the normal heating temperature, the larger the distance between the detection plate 42 and the trigger feedback mechanism 5, which is for the subsequent temperature triggering of different electric control components. The infrared temperature sensor 26 detects the temperature of the electric control component, and the PLC controller controls the power supply device to supply power to the force electromagnetic plate 54 based on the temperature monitoring value. The force electromagnetic plate 54 generates the same magnetism as the force permanent magnet plate 53 when it is energized, thereby generating a thrust on the pressure sensing plate 51, causing the pressure sensing plate 51 to move toward the detection plate 42. Specifically, the higher the heating temperature of the electric control component detected by the infrared temperature sensor 26, the greater the power supply device is to supply power to the force electromagnetic plate 54. The current makes the movement distance of the pressure sensing plate 51 greater. When the heating temperature of the detected electric control element exceeds the set threshold value relative to the standard heating temperature, the movement distance of the pressure sensing plate 51 is too large, causing the pressure sensing plate 51 to contact the detection plate 42, and also generates excessive pressure. The pressure sensing plate 51 feeds back the pressure signal to the PLC controller. After receiving the pressure signal feedback from the pressure sensing plate 51 exceeding the threshold value, the PLC controller promptly transmits a wireless signal to the receiving terminal of the staff to remind the staff to make corresponding detection and processing. Because the heating temperature of the electric control element is higher than the threshold value, it means that there is a problem with the use quality of the electric control element. As the use time increases, the electric control element will gradually age, and the semiconductor material and metal contact inside it will be damaged. Points will show wear, oxidation and other phenomena. For example, the contact resistance of the relay contacts will increase after long-term use, which will cause the heat generated at the contacts to increase under the same current. Aging capacitors will have problems such as leakage and reduced capacity, which will also increase the heat generated during operation. When the quality of the electronic control components is poor, their own power consumption will be large, which will cause more heat to be generated during normal operation. Moreover, when the components of poor quality are subjected to the same current and voltage, they are more likely to overheat and be damaged. By monitoring the heating temperature of the electronic control components, it can be fed back whether there are quality problems with the current electronic control components, and then the staff can be reminded to deal with it in time to avoid the problem that the poor quality of the electronic control components will affect the intelligent operation of the entire cooling unit.

[0044] And after detecting that the heating temperature of the current electric control element exceeds the threshold value and feeding back, the PLC controller controls the servo motor 44 to stop moving, so that the indicating rod 62 connected to the side wall of the moving seat 45 is aligned with the position of the electric control element on the position identification plate 61, facilitating the subsequent rapid positioning of the staff to the position of the electric control element with problems in the control cabinet 8.

[0045] The above only describes the preferred embodiments of the present application and is not intended to limit the present application.
