Description

Technical Field

[0001] The present invention relates to the medical field, and in particular to a heat dissipation system for power electronic high-voltage components used in industrial and medical equipment. Background Art

[0002] Power electronic high-voltage components are widely used in high-voltage generators and X-ray generators in the industrial and medical imaging fields, and transformer oil is usually used as the internal insulation and cooling medium. The transformer of the power electronic high-voltage generator and the tube core of the X-ray generator are both high-dissipation components, which emit a lot of heat in a very small volume during operation. This heat will be quickly released into the surrounding transformer oil. In order to avoid the core components from being unable to work normally due to excessive temperature and the transformer oil temperature rising too high, resulting in quality degradation and reduced insulation capacity, the oil temperature must be effectively reduced.

[0003] In the related art, heat is transferred to the housing of the component through convection and conduction of transformer oil, and then naturally dissipated by air or with the help of an external fan or other power cooling device.

[0004] In the process of realizing the present invention, the inventors found that there are at least the following problems in the related technology: this heat dissipation method is subject to the thermal conduction efficiency of the oil and the turbulence of the oil flow caused by the complex internal structure of the high-voltage generator or the ray generator. The heat transfer efficiency is very low and cannot be quickly dissipated to the outside. The oil temperature remains at a relatively high level for a long time, which can easily lead to oil degradation and reduced reliability of the generator. Summary of the invention

[0005] In order to solve or improve at least one of the above technical problems, an object of the present invention is to provide a heat dissipation system for power electronic high-voltage components in industrial and medical equipment.

[0006] To achieve the above-mentioned purpose, the present invention provides a heat dissipation system for power electronic high-voltage components used in industrial and medical equipment, comprising: a generator housing having a cavity, in which transformer oil is arranged; a high potential area, arranged in the cavity; a low potential area, arranged in the cavity, an electric field is formed between the high potential area and the low potential area, and the transformer oil can flow from the high potential area to the low potential area under the action of the electric field; a Tesla valve, connected to the generator housing, the Tesla valve having a Tesla valve pipe, the Tesla valve pipe is connected to the cavity, and the transformer oil can flow unidirectionally from the low potential area to the high potential area in the Tesla valve pipe.

[0007] According to the embodiment of the heat dissipation system for power electronic high-voltage components in industrial and medical equipment provided by the present invention, transformer oil flows from a high potential area to a low potential area under the action of an electric field (the inherent fluid properties of transformer oil), and transformer oil flows unidirectionally from a low potential area to a high potential area in a Tesla valve pipeline (the unidirectional properties of the Tesla valve), forming an efficient transformer oil circulation. The fluid circulation established by combining the fluid properties of transformer oil under an electric field and the unidirectional properties of the Tesla valve is stable and efficient, reduces the occurrence of turbulence, circulates rapidly, and dissipates heat efficiently, ensuring that the overall oil temperature is relatively low, slowing down the degradation of oil products, and ensuring long-term insulation properties. In addition, by utilizing the inherent fluid properties of transformer oil under a high-voltage electric field, no additional circulation power and device are required, simplifying the system design and cost, and being conducive to improving the reliability of the system.

[0008] Specifically, the heat dissipation system of power electronic high-voltage components used in industrial and medical equipment includes a generator housing, a high potential area, a low potential area and a Tesla valve. Among them, the generator housing has a cavity. Transformer oil is arranged in the cavity. Optionally, the generator housing is a housing of a high-voltage generator or a housing of an X-ray generator. Transformer oil is a mineral oil obtained by distillation and refining of natural petroleum. It is a mixture of pure, stable, low-viscosity, good insulation and good cooling liquid natural hydrocarbons obtained by acid and alkali refining of the lubricating oil fraction in petroleum. The main components of transformer oil include compounds such as alkanes, cycloalkane saturated hydrocarbons, and aromatic unsaturated hydrocarbons. Transformer oil serves as an insulating medium and a cooling medium in the housing.

[0009] Further, the high potential region is arranged in the cavity, and the low potential region is arranged in the cavity. The electric potential of the high potential region is greater than the electric potential of the low potential region. There is an electric potential difference between the high potential region and the low potential region. An electric field is formed between the high potential region and the low potential region. Optionally, the high potential region is an anode, and the low potential region is a cathode. The transformer oil can flow from the high potential region to the low potential region under the action of the electric field. Under normal circumstances, the oil temperature of the transformer oil in the high potential region is very high. This part of the transformer oil with a high oil temperature flows to the low potential region under the action of the electric field, which is conducive to reducing the oil temperature in the high potential region and achieving the purpose of active heat dissipation. In addition, the transformer oil near the high potential region will be replenished to the high potential region in time to cool the high potential region to ensure that the oil temperature in the high potential region is not too high. The present invention cleverly utilizes the characteristic that the transformer oil will flow from the high potential region to the low potential region under the high voltage electric field, and leaves an unobstructed space in the generator housing and between the high potential region and the low potential region to ensure that the transformer oil heated by cooling the high potential region can flow smoothly to the low potential region under the action of the electric field. In the technical solution defined in the present invention, the inherent fluid properties of transformer oil under high-voltage electric fields are utilized, and no additional circulation power and devices are required, which simplifies system design and costs and helps to improve system reliability.

[0010] Further, the Tesla valve is connected to the generator housing. The Tesla valve has a Tesla valve pipeline. The Tesla valve pipeline is connected to the cavity. Transformer oil can flow unidirectionally from the low potential area to the high potential area in the Tesla valve pipeline. Due to the structural characteristics of the Tesla valve, transformer oil can only flow unidirectionally in the Tesla valve pipeline (from the low potential area to the high potential area). By setting the Tesla valve, the transformer oil flowing to the low potential area under the action of the electric field is accelerated to flow back to the high potential area through the Tesla valve pipeline, and the transformer oil in the high potential area can be prevented from flowing to the low potential area through the Tesla valve pipeline. In the technical solution defined by the present invention, the transformer oil flows from the high potential area to the low potential area under the action of the electric field (the inherent fluid characteristics of the transformer oil), and the transformer oil flows unidirectionally from the low potential area to the high potential area in the Tesla valve pipeline (the unidirectional characteristics of the Tesla valve), forming an efficient transformer oil circulation. The fluid circulation established by combining the fluid characteristics of transformer oil under the electric field and the one-way characteristics of the Tesla valve is stable and efficient, which reduces the occurrence of turbulence, circulates quickly, and dissipates heat efficiently, ensuring that the overall oil temperature is relatively low, slowing down oil degradation, and ensuring long-term insulation properties.

[0011] In addition, the above technical solution provided by the present invention may also have the following additional technical features:

[0012] In the above technical solution, the Tesla valve pipeline has an inlet end and an outlet end, the distance between the inlet end and the low potential area is smaller than the distance between the inlet end and the high potential area; the distance between the outflow end and the high potential area is smaller than the distance between the outflow end and the low potential area.

[0013] In this technical solution, between the high potential area and the low potential area, the low potential area is closer to the inflow end of the Tesla valve pipe, and the high potential area is closer to the outflow end of the Tesla valve pipe. This design method can ensure that the transformer oil flowing to the low potential area under the action of the electric field is accelerated to flow back to the high potential area through the Tesla valve pipe, and can prevent the transformer oil in the high potential area from flowing to the low potential area through the Tesla valve pipe. The flow direction of the transformer oil is the high potential area, the low potential area, the inflow end of the Tesla valve pipe, the outflow end of the Tesla valve pipe, and the high potential area. Combining the fluid characteristics of the transformer oil under the electric field and the unidirectional characteristics of the Tesla valve, a stable and efficient fluid circulation is established.

[0014] In the above technical solution, the distance between the inflow end and the low potential area is consistent with the distance between the outflow end and the high potential area.

[0015] In this technical solution, the low potential area is closer to the inflow end, and the high potential area is closer to the outflow end, while the distance between the inflow end and the low potential area is consistent with the distance between the outflow end and the high potential area. This design can further ensure the stability and efficiency of fluid circulation, reduce the occurrence of turbulence, circulate quickly, dissipate heat efficiently, ensure the overall oil temperature is relatively low, slow down the deterioration of oil products, and ensure long-term insulation properties.

[0016] In the above technical solution, the number of Tesla valves is at least one.

[0017] In this technical solution, the number of Tesla valves is set to at least one, that is, the Tesla valves can be one, two or more, and the Tesla valves are flexibly set according to actual needs in consideration of the reflux efficiency of the transformer oil, the size of the occupied space, the cost and other factors.

[0018] In the above technical solution, the number of Tesla valves is at least two, at least one Tesla valve is arranged on one side of the generator housing, and at least one Tesla valve is arranged on the other side of the generator housing.

[0019] In this technical solution, the number of Tesla valves is at least two, that is, there can be two or more Tesla valves. At least one Tesla valve is provided on each side of the generator housing. This design method is conducive to increasing the reflux volume of transformer oil from the low potential area to the high potential area in the Tesla valve pipeline, and the circulation is faster and the heat dissipation is more efficient. Optionally, the specific number of Tesla valves is two, one Tesla valve is provided on one side of the generator housing, and the other Tesla valve is provided on the other side of the generator housing.

[0020] The above technical solution also includes: a heat dissipation device connected to the Tesla valve, and the heat dissipation device is used to dissipate heat from the transformer oil in the Tesla valve pipeline.

[0021] In this technical solution, the heat dissipation system of the power electronic high-voltage component also includes a heat dissipation device. Specifically, the heat dissipation device is connected to the Tesla valve. By providing the heat dissipation device, the transformer oil in the Tesla valve pipeline can be cooled, which is beneficial to further improve the heat dissipation effect of the fluid circulation. A heat dissipation device is provided on the valve body of the Tesla valve so that the transformer oil before returning to the high potential area can be well cooled. Optionally, the heat dissipation device is a heat pipe radiator or a water-cooled radiator. On the basis of stable fluid circulation, the transformer oil circulated to the outside is directly cooled, which improves the heat dissipation efficiency of the system, effectively reduces the temperature of the core components and transformer oil of the high voltage and ray generator, and ensures the working reliability and working time. In the technical solution defined by the present invention, an efficient and reliable fluid circulation cooling mode is formed.

[0022] In the above technical solution, the direction from the inlet end to the outlet end is the first direction, and the size of the Tesla valve pipeline in the first direction is not greater than the size of the heat dissipation device in the first direction.

[0023] In this technical solution, by setting the direction from the inlet end to the outlet end as the first direction, the size of the Tesla valve pipeline in the first direction is not larger than the size of the heat dissipation device in the first direction, which can ensure that the heat dissipation device and the Tesla valve have a sufficiently large contact area, which is conducive to further improving the heat dissipation effect.

[0024] The above technical solution also includes: a heat exchange device connected to the heat dissipation device.

[0025] In this technical solution, the heat dissipation system of the power electronic high-voltage component also includes a heat exchange device. Specifically, the heat exchange device is connected to the heat dissipation device. The heat exchange device and the heat dissipation device form a heat exchange system. The heat dissipation device can be understood as an internal unit, and the heat exchange device can be understood as an external unit.

[0026] In the above technical solution, the heat dissipation device is arranged on the side of the Tesla valve away from the generator housing.

[0027] In this technical solution, by arranging the heat dissipation device on the side of the Tesla valve away from the generator housing, on the one hand, it is helpful to standardize the spatial layout; on the other hand, it can ensure the contact area between the heat dissipation device and the Tesla valve pipeline, which is conducive to further improving the heat dissipation effect.

[0028] In the above technical solution, the number of heat dissipation devices is not less than the number of Tesla valves.

[0029] In this technical solution, the number of heat dissipation devices is greater than or equal to the number of Tesla valves. Taking into account the heat dissipation efficiency of the transmission oil in the Tesla valve pipeline, the size of the occupied space, the cost and other factors, the heat dissipation device is flexibly set according to actual needs.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0036] Refer to the following Figure 1 A heat dissipation system 100 for power electronic high-voltage components in industrial and medical equipment is described according to some embodiments of the present invention.

[0037] Embodiment 1

[0038] like Figure 1 As shown, a heat dissipation system 100 for power electronic high-voltage components in industrial and medical equipment provided by an embodiment of the present invention includes a generator housing 110, a high potential area 120, a low potential area 130 and a Tesla valve 140. Among them, the generator housing 110 has a cavity 111. Transformer oil is arranged in the cavity 111. Optionally, the generator housing 110 is a shell of a high-voltage generator or a shell of an X-ray generator. Transformer oil is a mineral oil obtained by distillation and refining of natural petroleum. It is a mixture of pure, stable, low-viscosity, good insulation and good cooling liquid natural hydrocarbons obtained by acid and alkali refining of the lubricating oil fraction in petroleum. The main components of transformer oil include compounds such as alkanes, cycloalkane saturated hydrocarbons, and aromatic unsaturated hydrocarbons. Transformer oil serves as an insulating medium and a cooling medium in the shell.

[0039] Further, the high potential region 120 is arranged in the cavity 111, and the low potential region 130 is arranged in the cavity 111. The electric potential of the high potential region 120 is greater than the electric potential of the low potential region 130. There is an electric potential difference between the high potential region 120 and the low potential region 130. An electric field is formed between the high potential region 120 and the low potential region 130. Optionally, the high potential region 120 is an anode, and the low potential region 130 is a cathode. The transformer oil can flow from the high potential region 120 to the low potential region 130 under the action of the electric field. Under normal circumstances, the oil temperature of the transformer oil in the high potential region 120 is very high. This part of the transformer oil with a high oil temperature flows to the low potential region 130 under the action of the electric field, which is conducive to reducing the oil temperature of the high potential region 120 and achieving the purpose of active heat dissipation. In addition, the transformer oil near the high potential region 120 will be replenished to the high potential region 120 in time, and the high potential region 120 is cooled to ensure that the oil temperature of the high potential region 120 will not be too high. The present invention cleverly utilizes the characteristic that transformer oil will flow from the high potential area 120 to the low potential area 130 under a high voltage electric field, and leaves an unobstructed space in the generator housing 110 and between the high potential area 120 and the low potential area 130, so as to ensure that the transformer oil heated by cooling the high potential area 120 can flow smoothly to the low potential area 130 under the action of the electric field. In the technical solution defined by the present invention, the inherent fluid characteristics of transformer oil under a high voltage electric field are utilized, and no additional circulation power and device are required, which simplifies the system design and cost, and is conducive to improving the reliability of the system.

[0040] Further, the Tesla valve 140 is connected to the generator housing 110. The Tesla valve 140 has a Tesla valve pipeline 141. The Tesla valve pipeline 141 is connected to the cavity 111. The transformer oil can flow unidirectionally from the low potential area 130 to the high potential area 120 in the Tesla valve pipeline 141. Due to the structural characteristics of the Tesla valve 140, the transformer oil can only flow unidirectionally (from the low potential area 130 to the high potential area 120) in the Tesla valve pipeline 141. By setting the Tesla valve 140, the transformer oil flowing to the low potential area 130 under the action of the electric field is accelerated to flow back to the high potential area 120 through the Tesla valve pipeline 141, and the transformer oil in the high potential area 120 can be prevented from flowing to the low potential area 130 through the Tesla valve pipeline 141. In the technical solution defined in the present invention, transformer oil flows from high potential area 120 to low potential area 130 under the action of electric field (inherent fluid characteristics of transformer oil), and transformer oil flows unidirectionally from low potential area 130 to high potential area 120 in Tesla valve pipe 141 (unidirectional characteristics of Tesla valve 140), forming an efficient transformer oil circulation. The fluid circulation established by combining the fluid characteristics of transformer oil under electric field and the unidirectional characteristics of Tesla valve 140 is stable and efficient, reduces the occurrence of turbulence, circulates quickly, and dissipates heat efficiently, ensuring that the overall oil temperature is relatively low, slowing down the degradation of oil products, and ensuring long-term insulation characteristics.

[0041] Embodiment 2

[0042] like Figure 1 As shown, the Tesla valve pipe 141 has an inflow end 142 and an outflow end 143, and the distance between the inflow end 142 and the low potential region 130 is smaller than the distance between the inflow end 142 and the high potential region 120; the distance between the outflow end 143 and the high potential region 120 is smaller than the distance between the outflow end 143 and the low potential region 130. Between the high potential region 120 and the low potential region 130, the low potential region 130 is closer to the inflow end 142 of the Tesla valve pipe 141, and the high potential region 120 is closer to the outflow end 143 of the Tesla valve pipe 141. This design can ensure that the transformer oil flowing to the low potential region 130 under the action of the electric field is accelerated to flow back to the high potential region 120 through the Tesla valve pipe 141, and can prevent the transformer oil in the high potential region 120 from flowing to the low potential region 130 through the Tesla valve pipe 141. The flow direction of the transformer oil is the high potential region 120, the low potential region 130, the inflow end 142 of the Tesla valve pipeline 141, the outflow end 143 of the Tesla valve pipeline 141, and the high potential region 120. Combining the fluid properties of the transformer oil under the electric field and the one-way characteristics of the Tesla valve 140, a stable and efficient fluid circulation is established.

[0043] Furthermore, the distance between the inflow end 142 and the low potential area 130 is consistent with the distance between the outflow end 143 and the high potential area 120. This design can further ensure stable and efficient fluid circulation, reduce the occurrence of turbulence, circulate quickly, dissipate heat efficiently, ensure a relatively low overall oil temperature, slow down oil degradation, and ensure long-term insulation properties.

[0044] Embodiment 3

[0045] like Figure 1 As shown, the number of Tesla valves 140 is at least one. By setting the number of Tesla valves 140 to at least one, that is, the Tesla valves 140 can be one, two or more, the Tesla valves 140 can be flexibly set according to actual needs in consideration of the reflux efficiency of transformer oil, the size of occupied space, cost and other factors.

[0046] In another embodiment, the number of Tesla valves 140 is at least two, at least one Tesla valve 140 is disposed on one side of the generator housing 110, and at least one Tesla valve 140 is disposed on the other side of the generator housing 110. The number of Tesla valves 140 is at least two, that is, the Tesla valves 140 can be two or more. At least one Tesla valve 140 is disposed on each side of the generator housing 110. This design method is conducive to increasing the reflux volume of transformer oil from the low potential area 130 to the high potential area 120 in the Tesla valve pipeline 141, and the circulation is faster and the heat dissipation is more efficient. Optionally, the specific number of Tesla valves 140 is two, one Tesla valve 140 is disposed on one side of the generator housing 110, and the other Tesla valve 140 is disposed on the other side of the generator housing 110.

[0047] Embodiment 4

[0048] like Figure 1 As shown, the heat dissipation system of the power electronic high-voltage component also includes a heat dissipation device 150. Specifically, the heat dissipation device 150 is connected to the Tesla valve 140. By providing the heat dissipation device 150, the transformer oil in the Tesla valve pipeline 141 can be cooled, which is beneficial to further improve the heat dissipation effect of the fluid circulation. The heat dissipation device 150 is provided on the valve body of the Tesla valve 140, so that the transformer oil before returning to the high potential area 120 can be well cooled. Optionally, the heat dissipation device 150 is a heat pipe radiator or a water-cooled radiator. On the basis of stable fluid circulation, the transformer oil circulated to the outside is directly cooled, which improves the heat dissipation efficiency of the system, effectively reduces the temperature of the core components and transformer oil of the high voltage and ray generator, and ensures the working reliability and working time. In the technical solution defined in the present invention, an efficient and reliable fluid circulation cooling mode is formed.

[0049] In another embodiment, the direction from the inflow end 142 to the outflow end 143 is a first direction, and the size of the Tesla valve conduit 141 in the first direction is not greater than the size of the heat sink 150 in the first direction. The size of the Tesla valve conduit 141 in the first direction is less than or equal to the size of the heat sink 150 in the first direction, which can ensure that the heat sink 150 and the Tesla valve 140 have a sufficiently large contact area, which is conducive to further improving the heat dissipation effect.

[0050] In another embodiment, the heat dissipation system of the power electronic high-voltage component further includes a heat exchange device 160. Specifically, the heat exchange device 160 is connected to the heat dissipation device 150. The heat exchange device 160 and the heat dissipation device 150 form a heat exchange system. The heat dissipation device 150 can be understood as an internal unit, and the heat exchange device 160 can be understood as an external unit.

[0051] In another embodiment, the heat sink 150 is disposed on a side of the Tesla valve 140 away from the generator housing 110. By disposing the heat sink 150 on a side of the Tesla valve 140 away from the generator housing 110, on the one hand, it is helpful to standardize the spatial layout; on the other hand, it can ensure the contact area between the heat sink 150 and the Tesla valve pipeline 141, which is helpful to further improve the heat dissipation effect.

[0052] In another embodiment, the number of the heat sinks 150 is not less than the number of the Tesla valves 140. The number of the heat sinks 150 is greater than or equal to the number of the Tesla valves 140, and the heat sinks 150 are flexibly arranged according to actual needs, taking into account the heat dissipation efficiency of the transmission oil in the Tesla valve pipeline 141, the size of the occupied space, the cost, and other factors.

[0053] According to the embodiment of the heat dissipation system of the power electronic high-voltage components in industrial and medical equipment of the present invention, the transformer oil flows from the high-potential area to the low-potential area under the action of the electric field (the inherent fluid characteristics of the transformer oil), and the transformer oil flows unidirectionally from the low-potential area to the high-potential area in the Tesla valve pipeline (the unidirectional characteristics of the Tesla valve), forming an efficient transformer oil circulation. The fluid circulation established by combining the fluid characteristics of the transformer oil under the electric field and the unidirectional characteristics of the Tesla valve is stable and efficient, reduces the occurrence of turbulence, circulates rapidly, and dissipates heat efficiently, ensures that the overall oil temperature is relatively low, slows down the degradation of the oil product, and ensures long-term insulation characteristics. In addition, by utilizing the inherent fluid characteristics of the transformer oil under the high-voltage electric field, no additional circulation power and device are required, which simplifies the system design and cost, and is conducive to improving the reliability of the system.
