Description

Technical Field

[0001] The invention relates to the field of transformers, and in particular to a high heat dissipation transformer with an internal air duct structure and a use method thereof. Background Art

[0002] A transformer is a facility that uses the principle of electromagnetic induction to change the voltage of alternating current. It is basic equipment for power transmission and distribution and is widely used in industries, agriculture, transportation, urban communities and other fields. It has functions such as voltage exchange, current exchange and voltage stabilization. Generally, during the use of the transformer, it will continue to generate heat, so the internal temperature needs to be dissipated and kept constant to avoid equipment failures caused by excessively high temperatures.

[0003] The existing patent (publication number: CN113643878B) discloses a high heat dissipation transformer with an internal air duct structure. In this invention, the heat-conducting connecting plate is a "human" shaped structure, and the heat is diffused through the heat-conducting connecting plate. The heat-conducting connecting plate can contact with the air to dissipate heat, and the heat dissipation effect is better in a windy environment. In the process of implementing the solution, the inventor found that the following problems in the prior art have not been well solved: 1. During use, the existing device uses the circulation of external air to drive the induced draft fan to rotate. However, in daily life, under normal weather, the wind speed in the natural environment is generally small, so that the cooling fan is driven only by natural wind, and the fan rotation effect is poor; 2. Secondly, during the use of the device, the external air is drained by the setting of air guide plates and air induced draft mechanisms, and the air is used to take away the temperature. However, in high temperature environments such as hot summers, the external air always maintains a certain temperature, so that the internal environment temperature drops slowly during the heat dissipation process, resulting in poor heat dissipation effect; 3. Moreover, when the device is idle, dust will inevitably accumulate. If the pipes, fans, etc. are not protected, dust will easily enter the interior of the device, so that when it is used again, large-scale cleaning is required, which is inconvenient for the use of the device.

[0016] A method for using a high heat dissipation transformer with an internal air duct structure, characterized in that it comprises the following steps:

[0017] S1. When the device is in use, the staff can drive the screw slide to operate through the motor on the screw slide. At this time, along with the rotation of the screw on the screw slide, the slider on the screw slide drives the negative pressure fan to move forward, the negative pressure fan moves forward, and pushes the limiting rod to move forward in the sealing cover. At the same time, since a number of straight tooth blocks are fixed on the side wall of one side of the limiting rod, the driving gear is driven to rotate, causing the L-shaped plug rod to rotate counterclockwise, and the L-shaped plug rod is reset to the inner wall of the sealing cover.

[0018] S2. As described above, the negative pressure fan continues to move forward and pushes the sealing cover out of the cooling duct through the limiting rod. At this time, the negative pressure fan is started by an external controller. The setting of the negative pressure fan makes the pressure inside the cooling duct different from that outside, causing the outside air to continuously enter the cooling duct. Since the cooling duct is additionally provided with a cooling bin, cooling gas or cryogenic liquid is injected through the liquid inlet valve to cool the air entering the duct.

[0019] S3. With the operation of the negative pressure fan, a large amount of air enters through the cooling duct and is cooled. Then the cooling gas enters the inner air guide duct in the heat dissipation base through the transmission duct. At this time, with the influx of gas, the internal air pressure rises, pushing the blocking block out of the movable groove, unblocking the airway, causing a large amount of cold air to flow into the device. Since the density of cold air is greater than that of hot air, the hot air inside the protective shell rises, reducing the internal ambient temperature and dissipating the heat to the transformer body. Then the hot air inside the protective shell is squeezed upward and released through the air outlet duct.

[0020] S4. As mentioned above, along with the output of the hot air flow inside the air outlet duct, the driven fan blades in the drainage duct will be driven to rotate, thereby rotating the multiple sets of suction fan blades on the shaft ends of the driven fan blades, and then the upper air flow inside the protective shell can be sucked in through the air inlet, and the air flow is gradually discharged through the adsorption fan and released together with the hot air flow in the air outlet duct, so that it is convenient to drive the components in the drainage duct through the multiple hot air flows, which is convenient for saving energy, and the increased air flow circulation increases the ventilation speed, which is convenient for rapid heat dissipation.

[0021] S5. When the device is in an idle state, the driving rod can be pushed forward manually, and the driving rod drives the connecting plate to move forward. The setting of several tooth grooves on the connecting plate can drive the transmission gear to rotate, and the transmission gear drives the blades to rotate counterclockwise to shield the air inlet to prevent dust from falling into the air inlet duct, and the outer wall of the driving rod is penetrated by an external screw to fix the driving rod on the side wall of the protective shell. At the same time, as mentioned above, due to the setting of the blocking block, the airway can be blocked when the equipment is idle to prevent dust from falling into the airway, and the screw slide can be used to drive the negative pressure fan to move backward, thereby driving the sealing cover to reset and block the inlet of the cooling duct, thereby preventing the entry of dust and other objects.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, by releasing the hot air flow along with the air outlet duct and utilizing the setting of the driven fan blades, a plurality of suction fan blades on the driven fan blades are indirectly driven to rotate, so that the hot air flow on the upper layer of the protective shell enters through the air inlet, is discharged again through the driven fan blades, and is merged with the hot air flow inside the air outlet duct for discharge. By increasing the exhaust volume, the circulation of the air flow is increased, the heat exchange operation is accelerated, and the heat dissipation is facilitated.

[0024] In the present invention, the negative pressure fan is driven forward by the screw slide. At this time, the limiting rod and the L-shaped plug-in rod are used. The limiting rod drives the L-shaped plug-in rod to rotate counterclockwise and contact the fixed structure, so that the negative pressure fan can be used to inhale external air. The external air is then cooled to a constant temperature through the cooling bin. The air is output through the internal air duct and the airway for rapid cooling. By continuously injecting cold air flow, the ambient temperature inside the protective shell is changed, thereby increasing the cooling effect.

[0025] In the present invention, the driving rod can be pushed forward to drive the connecting plate forward, and the tooth grooves on the driving rod can be used to close the multiple groups of blades to close the air inlet. At the same time, as mentioned above, the negative pressure fan and the sealing cover can be reset by the screw slide to close the cooling duct, thereby preventing dust and the like from entering the interior of the equipment when it is idle, causing inconvenience in later use.

At this time, with the influx of gas, the internal air pressure rises, pushing the blocking block 23 out of the movable groove, unblocking the airway 22, causing a large amount of cold air to flow into the device. Since the density of cold air is greater than that of hot air, the hot air inside the protective shell 1 rises, reducing the internal ambient temperature and dissipating the heat to the transformer body 3. Then the hot air inside the protective shell 1 is squeezed upward and released through the air outlet duct 5.

[0053] S4. As mentioned above, along with the output of the hot air flow inside the air outlet duct 5, the driven fan blades 62 in the drainage duct 61 will be driven to rotate, thereby rotating the multiple groups of suction fan blades 63 on the axial ends of the driven fan blades 62, and then the upper air flow inside the protective shell 1 can be sucked in through the air inlet, and the air flow is gradually discharged through the adsorption fan, and released together with the hot air flow in the air outlet duct 5, so that it is convenient to drive the components in the drainage duct 61 through the multiple hot air flows, which is convenient for saving energy, and the circulation of the air flow is increased, the ventilation speed is increased, and it is convenient for rapid heat dissipation.

8. The method for using the high heat dissipation transformer with an internal air duct structure according to claim 1, characterized in that: The steps include: S1. When the device is in use, the staff can drive the screw slide (44) to operate through the motor on the screw slide (44). At this time, along with the rotation of the screw on the screw slide (44), the slider on the screw slide (44) drives the negative pressure fan (41) to move forward, and the negative pressure fan (41) moves forward and pushes the limiting rod (433) to move forward in the sealing cover (42). At the same time, since a plurality of straight tooth blocks are fixed on the side wall of one side of the limiting rod (433), the driving gear (431) is driven to rotate, causing the L-shaped plug rod (432) to rotate counterclockwise, and the L-shaped plug rod (432) is reset to the inner wall of the sealing cover (42); S2, as described above, the negative pressure fan (41) continues to move forward, and pushes the sealing cover (42) out of the cooling pipe (4) through the limiting rod (433). At this time, the negative pressure fan (41) is started by the external controller. The setting of the negative pressure fan (41) makes the pressure inside the cooling pipe (4) different from that outside, so that the outside air continuously enters the cooling pipe (4). Since the cooling pipe (4) is additionally provided with a cooling chamber, cooling gas or low-temperature liquid is injected through the liquid inlet valve to cool the air entering the pipe; S3. With the operation of the negative pressure fan (41), a large amount of air enters through the cooling pipe (4) and is cooled. Then, the cooling gas enters the inner air guide pipe (21) in the heat dissipation base (2) through the transmission pipe. At this time, with the influx of gas, the internal air pressure rises, pushing the blocking block (23) out of the movable groove, unblocking the airway (22), causing a large amount of cold air to flow into the device. Since the density of cold air is greater than that of hot air, the hot air inside the protective housing (1) rises, reducing the internal ambient temperature and dissipating heat for the transformer body (3). Then, the hot air inside the protective housing (1) is squeezed upward and released through the air outlet pipe (5); S4, as described above, along with the output of the hot air flow inside the air outlet duct (5), the driven fan blades (62) in the drainage duct (61) are driven to rotate, thereby rotating the multiple groups of suction fan blades (63) on the shaft ends of the driven fan blades (62), and then the upper air flow inside the protective shell (1) can be sucked in through the air inlet, and the air flow is gradually discharged through the adsorption fan, and released together with the hot air flow in the air outlet duct (5), so that it is convenient to drive the components in the drainage duct (61) through the multiple hot air flows, which is convenient for saving energy, and the increased circulation of air flow increases the ventilation speed, which is convenient for rapid heat dissipation; S5. When the device is in an idle state, the driving rod (67) can be pushed forward manually, and the driving rod (67) drives the connecting plate (68) to move forward. The plurality of tooth grooves on the connecting plate (68) can be used to drive the transmission gear (66) to rotate, and the transmission gear (66) drives the blade (65) to rotate counterclockwise to shield the air inlet and prevent dust from falling into the air inlet duct (64). The driving rod (67) is fixed to the side wall of the protective housing (1) by penetrating the outer wall of the driving rod (67) through an external screw. At the same time, as described above, due to the setting of the blocking block (23), the air duct (22) can be blocked when the device is idle to prevent dust from falling into the air duct (22). The screw slide (44) can be used to drive the negative pressure fan (41) to move backward, thereby driving the sealing cover (42) to reset and blocking the inlet of the cooling duct (4), thereby preventing dust and other objects from entering.
