Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage drive power supplies, in particular to a high-voltage drive power supply with an independent air duct design. Background Art

[0002] A high-voltage drive power supply generally refers to a power supply that outputs a high DC voltage, and its output voltage generally reaches a range from several thousand volts to several million volts. High-voltage power supplies play a crucial role in industrial production and scientific research. For example, particle accelerators, X-ray generators, etc. all need to use high-voltage power supplies. A high-voltage power supply usually consists of a transformer, a rectifier, a filter, a voltage stabilizer, etc.

[0003] Traditional high-voltage drive power supplies usually adopt an overall air-cooling heat dissipation scheme. This heat dissipation method introduces cooling air flow into the power supply internally through forced convection. The heat dissipation air flow will flow through multiple key electronic components inside the power supply, including heat-generating components such as power semiconductor devices, transformers, and filter capacitors. Although this heat dissipation method can achieve a certain cooling effect, it will bring significant dust accumulation problems during long-term operation. Dust particles carried in the high-speed flowing air will be deposited on the surface of electronic components under the action of air flow disturbance. Secondly, since electronic components usually carry static electricity, it will further exacerbate the dust adsorption phenomenon. With the accumulation of operation time, a dust layer will continuously cover the surface of the components. This will not only reduce the heat dissipation efficiency of the components, but more importantly, will cause the surface insulation performance to gradually decline, ultimately affecting the reliability and service life of the power supply system, and may even cause safety accidents such as insulation failure in severe cases. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a high-voltage drive power supply with an independent air duct design.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A high-voltage drive power supply with an independent air duct design includes a housing. The housing is divided into an upper housing and a lower housing. An electronic component group is fixedly installed inside the upper housing. A partition is arranged between the upper housing and the lower housing. The partition is fixedly connected to the lower housing. A heat dissipation air duct is arranged between the partition and the lower housing. An air inlet is arranged on one side of the lower housing, and an air outlet is arranged on one side of the upper housing. An intake fan is fixedly installed at the air inlet.

[0007] By adopting the above technical solution, the partition can effectively construct a physical isolation barrier, so that the cooling air input by the intake fan is strictly restricted to flow within the heat dissipation air duct, completely avoiding the situation where the airflow directly scours the component group. This structural design not only effectively prevents the deposition of dust on the surface of sensitive electronic components, but also, through the heat conduction characteristics of the partition, efficiently conducts the heat generated when the component group works to the heat dissipation air duct area, and then takes it away by the forced convection airflow, realizing the collaborative optimization of heat dissipation and anti-fouling.

[0008] Furthermore, the heat dissipation air duct is composed of several heat sinks, and the shape of the heat sinks is set as wavy.

[0009] Furthermore, the heat sinks are arranged in an inclined shape.

[0010] By the above technical solution, for the wavy heat sinks, on the one hand, their special geometric configuration enhances the heat transfer efficiency by extending the airflow path, and on the other hand, with the help of the inclined arrangement, the dust attached to the surface of the heat sinks is more likely to fall off under the dual action of airflow scouring and gravity, and finally is discharged from the air outlet of the system along with the airflow.

[0011] Furthermore, a clamping plate is fixedly installed at the bottom end of the heat sink. A protrusion is arranged on one side of the clamping plate, and a groove is arranged on the other side of the clamping plate. The clamping plates are clamped through the protrusion and the groove.

[0012] By the above technical solution, the installation and disassembly between different clamping plates can be realized conveniently and quickly by using the protrusion and the groove.

[0013] Furthermore, a dust-repellent coating is applied on the surface of the heat sink.

[0014] Furthermore, a card slot is opened on the outer side of the lower shell. Both the lower shell and the upper shell are made of metal materials. A filter screen is arranged in the card slot. A magnetic attraction strip is fixedly installed on the inner side of the filter screen, and an extraction groove is arranged on the outer side of the filter screen.

[0015] By the above technical solution, the filter screen is detachably fixed on the lower shell through the magnetic attraction strip, which can not only ensure the efficient interception of dust particles in the external air, but also facilitate regular disassembly and cleaning, significantly reducing the risk of dust accumulation inside the drive power supply.

[0016] Furthermore, the partition and the heat sink are made of aluminum alloy with strong heat conduction performance.

[0017] Furthermore, a handle is fixedly installed on the outer side of the upper shell, and heat dissipation holes are opened on the upper surface of the upper shell.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. The utility model effectively constructs a physical isolation barrier by setting an intake fan, a partition board, and a heat dissipation air duct. By arranging a partition board between the component group and the heat dissipation air duct, the cooling air input by the intake fan can be strictly restricted to flow within the heat dissipation air duct, completely avoiding the situation where the air flow directly scours the component group. This structural design not only effectively prevents dust from depositing on the surface of sensitive electronic components, but also, through the heat conduction characteristics of the partition board, efficiently conducts the heat generated during the operation of the component group to the heat dissipation air duct area, and then takes it away by the forced convection air flow, realizing the coordinated optimization of heat dissipation and anti-fouling.

[0020] 2. The utility model sets a heat sink and a clamping plate. The interior of the heat dissipation air duct adopts a uniquely designed wavy heat sink. Its special geometric configuration enhances the heat exchange efficiency by extending the air flow path on the one hand, and on the other hand, makes the dust attached to the surface of the heat sink more likely to fall off under the dual action of air flow scouring and gravity, and finally is discharged from the air outlet of the system with the air flow. For the problem of local dust accumulation that may occur during long-term operation, a detachable clamping plate structure design is adopted, enabling maintenance personnel to easily take out the heat sink in the middle position for thorough cleaning, completely eliminating the problem of hard-to-clean dead corners in the traditional heat dissipation structure, and ensuring that the heat dissipation system always maintains the best working state.

[0021] 3. The utility model sets a filter screen and a magnetic strip. At the air inlet end, the multi-layer filter screen is detachably fixed on the lower shell through the magnetic strip, which can not only ensure the efficient interception of dust particles in the external air, but also facilitate regular disassembly and cleaning, significantly reducing the risk of dust accumulation inside the drive power supply.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0032] Refer to Figures 1 - 3 、 Figure 6 , a high-voltage drive power supply with an independent air duct design, including a housing 1, the housing 1 is divided into an upper shell 2 and a lower shell 3, a component group 4 is fixedly installed inside the upper shell 2, a partition 5 is arranged between the upper shell 2 and the lower shell 3, the partition 5 is fixedly connected to the lower shell 3, a heat dissipation air duct 6 is arranged between the partition 5 and the lower shell 3, an air inlet 7 is arranged on one side of the lower shell 3, an air outlet 8 is arranged on one side of the upper shell 2, an intake fan 9 is fixedly installed at the air inlet 7. By arranging a partition 5 between the component group 4 and the heat dissipation air duct 6, a physical isolation barrier can be effectively constructed, so that the cooling air input by the intake fan 9 is strictly restricted to flow in the heat dissipation air duct 6, completely avoiding the situation that the air flow directly flushes the component group 4. This structural design not only effectively prevents the deposition of dust on the surface of sensitive electronic components, but also through the heat conduction characteristics of the partition 5, efficiently conducts the heat generated when the component group 4 works to the heat dissipation air duct 6 area, and then is carried away by the forced convection air flow, realizing the coordinated optimization of heat dissipation and anti-pollution.

[0033] Refer to Figure 3 , specifically: the heat dissipation air duct 6 is composed of a plurality of heat sinks 10, the shape of the heat sinks 10 is set as a wavy shape, and the internal heat dissipation air duct 6 adopts heat sinks 10 with a unique design in a wavy shape, and its special geometric configuration enhances the heat exchange efficiency by extending the air flow path.

[0034] Reference Figure 4 、 Figure 8 Specifically, the heat sink 10 is arranged in an inclined shape. When the air flow blows towards the heat sink 10, the dust attached to the surface of the heat sink 10 is more likely to fall off under the dual action of the air flow scouring and gravity due to the inclined arrangement, and finally is discharged from the air outlet 8 of the system along with the air flow.

[0035] Reference Figure 3 、 Figure 5 Specifically, a clamping plate 11 is fixedly installed at the bottom end of the heat sink 10. A protrusion 12 is arranged on one side of the clamping plate 11, and a groove 13 is arranged on the other side of the clamping plate 11. The clamping plates 11 are clamped through the protrusion 12 and the groove 13. After long-term operation, if dust is locally attached to the heat sink 10 in the middle position, the clamping plate 11 can be directly taken out to clean the heat sink 10 in the middle position, reducing the cleaning dead angle.

[0036] Specifically, a dust-repellent coating is applied on the surface of the heat sink 10. The dust-repellent coating can be made of silicon dioxide. The dust-repellent coating prevents oil stains and moisture from adsorbing on the surface of the heat sink 10, avoiding dust from adhering and forming scale.

[0037] Reference Figure 3 、 Figures 7 - 8 Specifically, a card slot 14 is opened on the outer side of the lower shell 3. Both the lower shell 3 and the upper shell 2 are made of metal materials. A filter screen 15 is arranged in the card slot 14. A magnetic strip 16 is fixedly installed on the inner side of the filter screen 15, and an extraction groove 17 is arranged on the outer side of the filter screen 15. The filter screen 15 is adsorbed on the lower shell 3 through the magnetic strip 16, which can improve the installation convenience of the filter screen 15. When disassembling, the filter screen 15 can be taken out by simply pinching the extraction groove 17 with the hand.

[0038] Specifically, the partition 5 and the heat sink 10 are made of aluminum alloy with strong heat conduction performance, which is convenient for the heat generated during the operation of the component group 4 to be conducted into the heat dissipation air duct 6.

[0039] Reference Figure 1 、 Figure 6 Specifically, a handle 18 is fixedly installed on the outer side of the upper shell 2, and a heat dissipation hole 19 is opened on the upper surface of the upper shell 2. The handle 18 is convenient for the overall movement of the device. The heat dissipation hole 19 cooperates with the heat dissipation air duct 6 to achieve natural cooling and conduction air cold cooling, and the two heat dissipation paths are separated from each other, preventing cross-contamination of the air flow.

[0040] Working principle: By setting a partition 5 between the component group 4 and the heat dissipation air duct 6, a physical isolation barrier can be effectively constructed, so that the cooling air input by the intake fan 9 is strictly restricted to flow within the heat dissipation air duct 6, completely avoiding the situation where the airflow directly flushes the component group 4. This structural design not only effectively prevents the deposition of dust on the surface of sensitive electronic components, but also, through the heat conduction characteristics of the partition 5, efficiently conducts the heat generated during the operation of the component group 4 to the area of the heat dissipation air duct 6, and then takes it away by the forced convection airflow, realizing the coordinated optimization of heat dissipation and anti-fouling. At the air inlet 7 end, the multi-layer filter screen 15 is detachably fixed on the lower shell 3 through the magnetic strip 16, which can not only ensure the efficient interception of dust particles in the external air, but also facilitate regular disassembly and cleaning, significantly reducing the risk of dust accumulation inside the drive power supply. The inside of the heat dissipation air duct 6 is equipped with uniquely designed wavy heat sinks 10. On the one hand, its special geometric configuration enhances the heat exchange efficiency by extending the airflow path. On the other hand, with the help of the inclined arrangement, the dust attached to the surface of the heat sink 10 is more likely to fall off under the dual action of airflow scouring and gravity, and finally is discharged from the air outlet 8 with the airflow. For the local dust accumulation problem that may occur during long-term operation, the detachable snap plate 11 structure design is adopted, enabling maintenance personnel to easily take out the heat sink 10 in the middle position for thorough cleaning, completely eliminating the problem of hard-to-clean dead corners in the traditional heat dissipation structure, and ensuring that the heat dissipation system always maintains the best working state. This overall optimized design not only ensures the heat dissipation performance, but also greatly improves the dust-proof ability and maintenance convenience of the equipment.
