Description

Technical Field

[0001] This invention relates to the field of electrical control cabinet technology, and specifically discloses an energy-saving electrical control cabinet. Background Technology

[0002] Electrical control cabinets are indispensable equipment in industrial production, integrating a large number of switching devices, measuring instruments, and protective electrical appliances. These electrical components generate a significant amount of heat during operation. Traditional electrical control cabinet cooling systems, such as cooling fans, often operate continuously independent of the equipment's running status. Regardless of the internal temperature of the cabinet, the fans maintain full or constant speed, leading to a substantial amount of unnecessary energy waste.

[0003] Meanwhile, humidity inside the cabinet is also a significant factor affecting the safe operation of electrical components. Excessive humidity can lead to short circuits or component corrosion, and most existing control cabinets lack the function of automatically adjusting the internal environment based on humidity levels, resulting in poor adaptability. Therefore, there is an urgent need for an electrical control cabinet that can automatically and efficiently activate heat dissipation and ventilation structures based on the actual temperature and humidity inside the cabinet, thereby achieving energy-saving operation. Summary of the Invention

[0004] This invention proposes an energy-saving electrical control cabinet. Through the real-time acquisition of environmental parameters by temperature and humidity monitoring modules, and the intelligent start-stop and adjustment of cooling fans and ventilation louvers by the control module according to preset thresholds, the energy waste caused by the continuous full-speed operation of traditional equipment is avoided, thereby reducing the operating energy consumption of the control cabinet.

[0005] This invention is implemented as follows: an energy-saving electrical control cabinet includes a cabinet body and electrical components installed inside the cabinet body, and further includes:

[0006] An environmental parameter monitoring module is installed inside the cabinet to monitor the environmental parameters inside the cabinet in real time and output corresponding monitoring signals.

[0007] A control module is installed on the cabinet, and the input terminal of the control module is electrically connected to the environmental parameter monitoring module for receiving and processing the monitoring signals.

[0008] A heat dissipation module is installed on the cabinet, electrically connected to the output terminal of the control module, and controlled by the control module to dissipate heat from the cabinet.

[0009] A ventilation adjustment module is installed on the wall of the cabinet, electrically connected to the output terminal of the control module, and controlled by the control module to adjust the air circulation state inside and outside the cabinet.

[0010] The system also includes a power supply module, which is installed inside the cabinet. Its input end is used to connect to an external power source, and its output end is electrically connected to the control module, the heat dissipation execution module, and the ventilation regulation module, respectively, to provide power to each module.

[0011] Preferably, the environmental parameter monitoring module includes a temperature monitoring module for monitoring the temperature inside the cabinet and a humidity monitoring module for monitoring the humidity inside the cabinet.

[0012] Preferably, there are multiple temperature monitoring modules and multiple humidity monitoring modules, which are distributed at different heights within the cabinet.

[0013] Preferably, the heat dissipation execution module includes a cooling fan installed on the top of the cabinet and heat dissipation fins disposed on the side wall of the cabinet, and the cooling fan is electrically connected to the output terminal of the control module.

[0014] Preferably, the heat dissipation fins are multiple and evenly distributed on the outer surface of the side wall of the cabinet.

[0015] Preferably, the ventilation adjustment module includes an air inlet located at the bottom of the cabinet and an air outlet located at the top of the cabinet.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0025] Please see Figure 1-3 An energy-saving electrical control cabinet includes a cabinet body 1 and electrical components installed inside the cabinet body 1, and further includes:

[0026] An environmental parameter monitoring module is installed inside cabinet 1 to monitor the environmental parameters inside cabinet 1 in real time and output corresponding monitoring signals.

[0027] Control module 4 is installed on cabinet 1. The input terminal of control module 4 is electrically connected to the environmental parameter monitoring module and is used to receive and process monitoring signals.

[0028] The heat dissipation module is installed on the cabinet 1, electrically connected to the output terminal of the control module 4, and controlled by the control module 4 to dissipate heat from the cabinet 1.

[0029] The ventilation adjustment module is installed on the wall of the cabinet 1, electrically connected to the output terminal of the control module 4, and controlled by the control module 4 to adjust the air circulation state inside and outside the cabinet 1.

[0030] And the power supply module 10, which is installed inside the cabinet 1, has an input end for connecting to an external power source, and an output end for electrically connecting to the control module 4, the heat dissipation execution module and the ventilation regulation module, respectively, to provide power to each module.

[0031] In this embodiment: after the electrical control cabinet is powered on, the temperature monitoring module 2 and humidity monitoring module 3, which are distributed at different heights within the cabinet 1, begin to collect real-time temperature and humidity data and transmit these monitoring signals to the control module 4. The control module 4 has preset temperature and humidity thresholds. It compares and makes logical judgments with the received real-time data: when the temperature inside the cabinet exceeds the preset threshold, the control module 4 sends a control signal to the cooling fan 5 through its PWM output terminal to start the cooling fan 5 and adjust its speed according to the degree of temperature deviation. At the same time, the heat dissipation fins 6 set on the side wall of the cabinet 1 help to increase the heat dissipation area and force the heat inside the cabinet 1 to be expelled. When the humidity inside the cabinet exceeds the preset threshold, the control module 4 sends a control command to the drive of the ventilation louvers 9 to adjust the opening and closing angle of the ventilation louvers 9 set at the air inlet 7 at the bottom and the air outlet 8 at the top of the cabinet 1 to enhance the air convection inside and outside the cabinet 1 and reduce the humidity inside the cabinet. Throughout the operation, the power supply module 10, as a switching power supply module with a pulse width modulation output, can dynamically adjust the power output to the cooling fan 5 and the ventilation louvers 9 drive components according to the load demand signal output by the control module 4, thus achieving on-demand power supply. Based on this principle, this embodiment enables the starting and stopping, speed of the cooling fan 5, and the opening and closing angle of the ventilation louvers 9 to automatically adjust according to the actual changes in temperature and humidity inside the cabinet, avoiding continuous full-speed operation of the cooling and ventilation equipment, thereby achieving significant energy savings while ensuring the operating environment of electrical components.

[0032] As a technical optimization of the present invention, the environmental parameter monitoring module includes a temperature monitoring module 2 for monitoring the temperature inside the cabinet and a humidity monitoring module 3 for monitoring the humidity inside the cabinet.

[0033] In this embodiment, two different types of sensors independently collect two key environmental parameters—temperature and humidity—within the cabinet, enabling the control module 4 to obtain multi-dimensional environmental information. The temperature monitoring module 2 and humidity monitoring module 3 have clearly defined roles and responsibilities, accurately reflecting the heat load within the cabinet and promptly detecting abnormal humidity changes.

[0034] As a technical optimization of the present invention, there are multiple temperature monitoring modules 2 and humidity monitoring modules 3, which are distributed at different heights inside the cabinet 1.

[0035] In this embodiment: by using a multi-point layout in the vertical direction within the cabinet 1, the data deviation that may be caused by a single-location measurement is eliminated, making the monitoring data obtained by the control module 4 more representative and comprehensive. Since the heat accumulation and humidity distribution at different heights within the electrical control cabinet often differ, the multi-point distributed layout can effectively avoid the fan from starting incorrectly or failing to start in time due to local anomalies, thereby improving the accuracy of environmental monitoring and the reliability of system control.

[0036] As a technical optimization of the present invention, the heat dissipation execution module includes a heat dissipation fan 5 installed on the top of the cabinet 1 and heat dissipation fins 6 disposed on the side wall of the cabinet 1. The heat dissipation fan 5 is electrically connected to the output terminal of the control module 4.

[0037] In this embodiment, a dual heat dissipation architecture combining forced air cooling and natural heat dissipation is adopted. The cooling fan 5 is controlled by the PWM signal of the control module 4 to start, stop, and adjust its speed, while the heat dissipation fins 6 continuously provide passive heat dissipation. When the temperature is low, heat dissipation mainly relies on the natural cooling of the heat dissipation fins 6. When the temperature rises, the cooling fan 5 starts as needed and adjusts its speed, ensuring efficient heat dissipation under high heat load conditions while avoiding energy waste caused by the cooling fan 5 running at full speed for extended periods.

[0038] As a technical optimization of the present invention, the heat dissipation fins 6 are multiple and evenly distributed on the outer surface of the side wall of the cabinet 1.

[0039] In this embodiment: by increasing the number of heat dissipation fins 6 and arranging them evenly on the outer surface of the side wall of the cabinet 1, the heat exchange area between the cabinet 1 and the external environment is expanded, while ensuring that heat is evenly conducted and dissipated along the side wall of the cabinet 1.

[0040] As a technical optimization of the present invention, the ventilation adjustment module includes an air inlet 7 at the bottom of the cabinet 1 and an air outlet 8 at the top of the cabinet 1. Both the air inlet 7 and the air outlet 8 are provided with ventilation louvers 9, and the ventilation louvers 9 are electrically connected to the output terminal of the control module 4 through a driving component.

[0041] In this embodiment, utilizing the physical property of hot air rising naturally, cool air is introduced through the bottom air inlet 7 and hot air is discharged through the top air outlet 8, forming a natural convection channel from bottom to top. Simultaneously, the control module 4 adjusts the opening angle of the ventilation louvers 9 via a drive mechanism to control the ventilation volume. The vertical arrangement of the air inlet 7 and air outlet 8 conforms to the flow pattern of hot air, improving natural ventilation efficiency. The adjustable ventilation louvers 9 allow for flexible adjustment of the ventilation volume according to humidity changes, effectively reducing humidity inside the cabinet while avoiding energy loss due to excessive ventilation.

[0042] As a technical optimization of the present invention, the power supply module 10 is a switching power supply module with a pulse width modulation output terminal, which dynamically adjusts the power supply output to the heat dissipation execution module and the ventilation regulation module according to the load demand signal output by the control module 4.

[0043] In this embodiment, the power supply module 10 responds in real time to the load demand signal of the control module 4 through its pulse width modulation output terminal, and dynamically adjusts the output voltage or current according to the actual working state of the cooling fan 5 and the ventilation louver 9 drive components.

[0044] Working principle and usage process of this invention:

[0045] When the electrical control cabinet is powered on, multiple temperature monitoring modules 2 and humidity monitoring modules 3 installed at different heights inside the cabinet 1 begin to work in real time, collecting temperature and humidity data at various heights inside the cabinet 1 and transmitting these monitoring signals to the input terminal of the control module 4. The comparator circuit inside the control module 4 compares the received temperature data with a preset temperature threshold and the humidity data with a preset humidity threshold, and makes a logical decision based on the comparison results: When the actual temperature inside the cabinet 1 exceeds the preset temperature start threshold in the control module 4, the control module 4 outputs a PWM control signal to the cooling fan 5 installed on the top of the cabinet 1 through its PWM output terminal, and the cooling fan 5 starts running. The control module 4 adjusts the duty cycle of the PWM signal according to the degree of temperature exceedance, thereby adjusting the speed of the cooling fan 5 so that the fan runs continuously at a speed that matches the cooling demand. At the same time, multiple heat dissipation fins 6 set on the outer surface of the side wall of the cabinet 1 play an auxiliary role in heat dissipation, forcibly expelling the heat inside the cabinet 1 to the external environment; When the actual temperature inside the cabinet 1 falls below the preset temperature stop threshold, the control module 4 stops outputting the PWM control signal, and the cooling fan 5 stops running. Meanwhile, when the actual humidity inside the cabinet 1 exceeds the preset humidity threshold in the control module 4, the control module 4 outputs control commands to the drive components of the ventilation louvers 9 located at the air inlet 7 and the air outlet 8. The drive components drive the blades of the ventilation louvers 9 to rotate to the preset opening angle, thereby increasing the ventilation area of ​​the air inlet 7 and the air outlet 8. External air enters the cabinet 1 through the bottom air inlet 7, flows through the internal space of the cabinet 1, and is discharged from the top air outlet 8, forming a bottom-up convection airflow that accelerates the discharge of humid air from the cabinet 1. When the actual humidity inside the cabinet 1 falls below the preset humidity threshold, the control module 4 controls the drive components to reverse their action, restoring the ventilation louvers 9 to the initial opening angle and reducing unnecessary airflow. Throughout the entire operation, the power supply module 10 receives the load demand signal output by the control module 4 in real time, and dynamically adjusts the power supply output to the cooling fan 5 and the ventilation louver 9 through its pulse width modulation output terminal, so that the cooling fan 5 and the drive unit can obtain power supply that matches the real-time load under different working conditions. Each module cyclically executes the above monitoring, comparison, control, action and power supply adjustment steps, thereby realizing continuous intelligent control of the entire working process.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
