Abstract
Description
Technical Field
[0001] This application relates to the field of electrical control cabinet technology, and more specifically, to an automatic heat dissipation and adjustment device for an intelligent electrical control cabinet. Background Technology
[0002] As the core control unit of industrial automation systems, power distribution networks and precision electronic equipment, intelligent electrical control cabinets integrate a large number of electronic components such as frequency converters, PLC controllers, relays, and contactors. These components continuously generate heat during operation, causing the temperature inside the cabinet to rise.
[0003] In related technologies, for example, the prior art patent with publication number CN221747778U provides a heat dissipation device for an electrical control cabinet, belonging to the field of heat dissipation devices. It includes a cabinet body and a cabinet door. The heat dissipation mechanism is set up in conjunction with the use of the cabinet body. A second heat dissipation fan can introduce external cold air through a T-shaped air duct and blow the cold air into the cabinet body through the air inlet on the bottom of the cabinet body to achieve air cooling heat dissipation for the electrical components inside the cabinet. Before the external air enters the T-shaped air duct, the filter screen installed in the filter frame inside the input end on both sides can filter and block the dust in the air, which can prevent the dust in the air from entering the cabinet body and affecting the use of electrical components during air cooling heat dissipation.
[0004] However, its heat dissipation window opening is constant and cannot be adjusted according to real-time temperature changes inside the cabinet. When the electrical control cabinet is operating under low load and generating less heat, an excessively large heat dissipation window opening will cause excessive cold air to rush in, which not only wastes energy but may also cause condensation due to excessive temperature difference. On the other hand, when under high load and the temperature inside the cabinet rises sharply, the fixed small opening is difficult to meet the demand for rapid heat dissipation, causing the components to be in a high-temperature environment for a long time, resulting in decreased performance and shortened life.
[0005] In view of this, we propose an automatic heat dissipation regulation device for intelligent electrical control cabinets. Utility Model Content
[0006] The purpose of this application is to provide an automatic heat dissipation adjustment device for an intelligent electrical control cabinet, which can effectively solve the problems in the prior art where the opening of the heat dissipation window is constant and cannot be adjusted according to the real-time temperature changes inside the cabinet. When the electrical control cabinet is operating under low load and generating less heat, an excessively large opening of the heat dissipation window will cause excessive cold air to rush in, which not only wastes energy but may also cause condensation due to excessive temperature difference. At high load and when the temperature inside the cabinet rises sharply, a fixed small opening is difficult to meet the demand for rapid heat dissipation, causing components to be in a high-temperature environment for a long time, resulting in performance degradation and shortened life. The application realizes that the heat dissipation window driven by phase change material can automatically and linearly adjust the opening according to the temperature, and always maintain an appropriate heat dissipation intensity effect.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0016] This application effectively solves the problem of constant heat dissipation window opening, which cannot be adjusted according to real-time temperature changes inside the cabinet. When the electrical control cabinet is operating under low load and generating less heat, an excessively large heat dissipation window opening will cause excessive cold air to rush in, which not only wastes energy but may also cause condensation due to excessive temperature difference. At high load and when the temperature inside the cabinet rises sharply, a fixed small opening is difficult to meet the demand for rapid heat dissipation, causing components to be in a high-temperature environment for a long time, resulting in performance degradation and shortened life. This application realizes that the heat dissipation window driven by phase change material can automatically and linearly adjust its opening according to temperature, always maintaining an appropriate heat dissipation intensity.
[0017] This application utilizes a power component that drives the rotating hinges in the heat dissipation adjustment mechanism via a phase change material. This allows the opening of the heat dissipation window to be controlled based on temperature changes inside the control cabinet, enabling adaptive adjustment of the heat dissipation intensity.

Detailed Implementation
[0025] The present application will be further described in detail below with reference to the accompanying drawings.
[0026] Reference Figures 1 to 5 This application discloses an automatic heat dissipation adjustment device for an intelligent electrical control cabinet, which includes a control cabinet body 1; a heat dissipation adjustment mechanism is provided on one side of the control cabinet body 1.
[0027] The heat dissipation adjustment mechanism includes a heat dissipation fan 2; there are two heat dissipation fans 2 arranged symmetrically; the air inlet of the heat dissipation fan 2 is located inside the control cabinet body 1; a mounting frame 3 is fixedly installed on the side wall of the control cabinet body 1; a rotating hinge 4 is hinged inside the mounting frame 3; a rotating rod 5 is installed in the rotating hinge 4; the rotating rod 5 extends to the outside of the mounting frame 3; a connecting plate 6 is fixedly installed on the rotating rod 5; a connecting rod 7 is fixedly installed on the connecting plate 6; a power component is installed at the lower end of the connecting rod 7.
[0028] By setting up a control cabinet body 1 and a heat dissipation adjustment mechanism, the heat dissipation adjustment mechanism can dissipate heat from the control cabinet body 1 during use, and adaptively adjust the opening angle of the heat dissipation on the control cabinet body 1 according to the internal temperature of the control cabinet body 1. The heat dissipation adjustment mechanism includes a cooling fan 2, a mounting frame 3, a rotating hinge 4, a rotating rod 5, a connecting plate 6, a connecting rod 7, and a power component. During use, the cooling fan 2 is fixed in the mounting frame 3, and the cooling fan 2 can dissipate the temperature inside the control cabinet body 1. Then, the rotating rod 5 is set in the mounting frame 3, and the rotating hinge 4 is rotated and connected to the rotating rod 5. When the internal temperature of the control cabinet body 1 changes, the power component drives the connecting rod 7 to move, which in turn causes the rotating rod 5 to drive the rotating hinge 4 to rotate. Thus, the opening and closing angle of the rotating hinge 4 is automatically adjusted according to the internal temperature of the control cabinet, so that it is always maintained at a suitable heat dissipation angle.
[0029] Reference Figure 4 and Figure 5 The power assembly includes a fixed tube 8; the lower end of the connecting rod 7 is located inside the fixed tube 8; the other end of the fixed tube 8 extends into the interior of the control cabinet body 1; a heat-conducting plate 9 is provided inside the control cabinet body 1; the fixed tube 8 is in contact with the heat-conducting plate 9; the interior of the fixed tube 8 is filled with solid paraffin; a horizontal plate 10 is fixedly provided at the lower end of the connecting rod 7; the horizontal plate 10 is located inside the fixed tube 8.
[0030] By setting up a fixed tube 8, a heat-conducting plate 9, and a horizontal plate 10, when the electronic components inside the control cabinet body 1 generate heat during operation, the heat is quickly conducted to the fixed tube 8 through the heat-conducting plate 9 which is in contact with the fixed tube 8. When the solid paraffin filling the fixed tube 8 is heated, it changes from solid to liquid as the temperature rises. The expanding paraffin will exert an upward thrust on the horizontal plate 10 located inside the fixed tube 8. When the temperature inside the control cabinet body 1 decreases, the solid paraffin gradually solidifies due to heat loss, shrinks in volume, and the thrust on the horizontal plate 10 disappears. Through the rotation of the hinge 4 and the influence of the gravity of the connecting plate 6, the connecting rod 7 is pulled downward.
[0031] Reference Figure 1 The mounting frame 3 is provided with a first dustproof plate 11; the first dustproof plate 11 is detachably fixed to the mounting frame 3 by bolts.
[0032] By setting the first dustproof plate 11, during use, the first dustproof plate 11 can prevent dust particles in the outside air from entering the interior of the control cabinet body 1, and prevent dust particles from adhering to electrical components and affecting the electrical components.
[0033] Reference Figure 2 An air inlet 12 is provided on the side wall of the control cabinet body 1; a second dustproof plate 13 is fixedly installed on the air inlet 12.
[0034] By setting up an air inlet 12 and a second dustproof plate 13, during use, the air inlet 12 and the cooling fan 2 form convection, which enables the low-temperature outside air to exchange heat with the high-temperature air inside the control cabinet body 1. Then, the second dustproof plate 13 can prevent impurities in the outside air from entering the interior of the control cabinet body 1.
[0035] Reference Figure 1 A movable door 14 is rotatably connected to the control cabinet body 1; a handle 15 is fixedly installed on the movable door 14.
[0036] By setting up the movable door 14 and the handle 15, the handle 15 can provide a point of leverage for the staff during use, making it convenient for the staff to open and close the movable door 14 and to inspect the electrical components inside the control cabinet body 1.
[0037] Reference Figure 1 The lower surface of the control cabinet body 1 is fixedly provided with support legs 16; there are four support legs 16 arranged symmetrically.
[0038] By setting up support legs 16, the support legs 16 can provide support for the staff during use, and increase the ground clearance of the control cabinet body 1.
[0039] Reference Figure 5 The horizontal plate 10 is smoothly connected to the inner wall of the fixed tube 8.
[0040] By making the inner walls of the horizontal plate 10 and the fixed tube 8 smooth, the friction between the horizontal plate 10 and the fixed tube 8 can be reduced, allowing the horizontal plate 10 to move better inside the fixed tube 8.
[0041] In summary, the automatic heat dissipation adjustment device for an intelligent electrical control cabinet disclosed in this application operates as follows: First, the cooling fan 2 is fixed inside the mounting frame 3. The cooling fan 2 dissipates heat from the inside of the control cabinet body 1. Then, the rotating rod 5 is installed in the mounting frame 3, and the rotating hinge 4 is connected to the rotating rod 5. When the temperature inside the control cabinet body 1 changes, the power component drives the connecting rod 7 to move, which in turn causes the rotating rod 5 to rotate the rotating hinge 4. The opening and closing angle of the rotating hinge 4 is automatically adjusted according to the temperature inside the control cabinet to maintain a suitable heat dissipation angle. Then, when the electronic components inside the control cabinet body 1 generate heat, the heat is quickly conducted to the fixed tube 8 through the heat-conducting plate 9 in contact with the fixed tube 8. The solid paraffin filling inside the fixed tube 8 changes from solid to liquid as the temperature rises. The expanded paraffin exerts an upward thrust on the horizontal plate 10 located inside the fixed tube 8. When the temperature inside the control cabinet body 1 decreases, the solid paraffin is released due to the heat. As the dust gradually solidifies and shrinks in volume, the thrust on the horizontal plate 10 disappears. Due to the influence of the rotation of the hinge 4 and the gravity of the connecting plate 6, the connecting rod 7 is pulled downward. The first dustproof plate 11 can prevent dust particles in the outside air from entering the interior of the control cabinet body 1 and prevent dust particles from adhering to the electrical components and affecting them. The air inlet 12 and the cooling fan 2 form convection, which can enable the low-temperature outside air to exchange heat with the high-temperature air inside the control cabinet body 1. Then, the second dustproof plate 13 can prevent impurities in the outside air from entering the interior of the control cabinet body 1. The handle 15 can provide a point of leverage for the staff to open and close the movable door 14 and facilitate the staff to inspect the electrical components inside the control cabinet body 1. The support leg 16 can provide support for the staff and increase the ground clearance of the control cabinet body 1. Finally, the smooth inner wall of the horizontal plate 10 and the fixed tube 8 can reduce the friction between the horizontal plate 10 and the fixed tube 8 and enable the horizontal plate 10 to move better inside the fixed tube 8.
