Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an anode heat dissipation component of an X-ray tube. Background Art

[0002] When the high-energy electrons emitted from the filament end reach the anode target, only 1% of the energy generated is converted into useful X-rays, and the remaining 99% is converted into heat, which is mainly dissipated through the anode copper column. Therefore, when the tube is working, the anode will generate a large amount of heat. If the heat is not dissipated in time, the anode will overheat and produce evaporation, which will cause the vacuum in the tube to decrease and cause discharge in the tube. In more serious cases, the anode target may melt, shortening the working life of the anode target.

[0003] Currently, the main heat dissipation method on the market is oil cooling. Oil cooling uses the fluidity of oil to quickly transfer heat from high-heat areas to low-heat areas. However, in order to seal the insulating oil, it needs to be wrapped in a metal shell. Therefore, the X-ray source assembly will have a large weight. In addition, the oil-cooled heat dissipation assembly will also take up a large space. In order to reduce weight, there are X-ray source assemblies that use silicone rubber as an insulating medium and plastic as an X-ray source assembly shell. However, since silicone does not have fluidity, the heat dissipation efficiency is not as good as insulating oil. It is easy to cause excessive heat accumulation at the anode, resulting in abnormal operation of the tube. High temperature will also cause cracks and bubbles in the silicone, causing insulation failure, resulting in low heat dissipation efficiency and low reliability. Summary of the invention

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides an X-ray tube anode heat dissipation assembly, which can solve the problems of heavy weight, large space occupation, low reliability and low heat dissipation efficiency caused by oil cooling of the X-ray tube anode.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] An X-ray tube anode heat dissipation assembly, comprising:

[0007] An X-ray tube, the X-ray tube comprising a glass shell and an anode copper column, one end of the anode copper column is located inside the glass shell, and the other end is located outside the glass shell;

[0008] An insulating heat-conducting member, one end of which is connected to the anode copper column;

[0009] Thermal storage module;

[0010] A heat pipe, wherein the heat pipe is respectively attached to the insulating heat conductive member and the heat storage module;

[0011] A shell, wherein a cavity is provided inside the shell, the glass shell and the anode copper column are located in the cavity, the insulating heat conductive member is arranged through the side wall of the shell, the portion of the insulating heat conductive member located inside the shell is connected to the anode copper column, and the portion of the insulating heat conductive member located outside the shell is attached to the heat pipe;

[0012] Wherein, the heat storage module is used to store the heat transferred by the insulating heat conductive member to the heat pipe.

[0013] By adopting the above solution, heat can be quickly transferred from the anode copper column to the heat storage module through the insulating thermal conductive parts and heat pipes with high thermal conductivity. This structure can significantly improve the heat dissipation efficiency and reduce the temperature accumulation in the anode area, thereby ensuring the stable operation of the X-ray tube. In addition, the efficient heat dissipation system can effectively prevent the anode from overheating and avoid the generation of evaporation caused by high temperature, thereby maintaining the vacuum degree in the tube and preventing discharge in the tube and melting of the anode target. This helps to extend the overall service life of the X-ray tube.

[0014] A cavity is provided inside the shell to accommodate the glass shell and the anode copper column, and the insulating heat conductor passes through the side wall of the shell to connect the anode copper column with the external heat pipe. Compared with the oil cooling system with more components, the structure of the present application is compact and space utilization is efficient.

[0015] By using heat pipes and heat storage modules, the system can maintain stable heat dissipation performance for a long time. Even in the case of long-term continuous operation, the anode temperature can be effectively controlled to ensure the reliable operation of the equipment.

[0016] The heat storage module can be made of a material with large latent heat, which can always maintain a large temperature difference with the heat pipe, thereby ensuring heat transfer efficiency, and further effectively controlling the anode temperature under long-term continuous operation.

[0017] In addition, the insulating thermal conductive parts are usually made of materials with high thermal conductivity. The insulating thermal conductive parts must also have excellent electrical insulation properties to ensure electrical isolation between the anode copper column and the external structure. This can be achieved by selecting suitable insulating materials, which usually have high dielectric strength and voltage resistance characteristics.

[0018] Furthermore, the heat pipe includes a transition portion and an extension portion, the transition portion is connected to the extension portion, the transition portion is respectively fitted with the insulating heat conductive member and the heat storage module, and the extension portion is arranged on the outer surface of the shell in a curved shape.

[0019] By adopting the above scheme, the extension portion is arranged on the outer surface of the shell in a bent state, which can increase the heat dissipation area, significantly improve the heat dissipation efficiency, and reduce the heat accumulation of the anode copper column. By organically combining the heat pipe with the heat storage module, the temperature of the anode area can be effectively controlled to prevent overheating, thereby extending the service life of the X-ray tube.

[0020] Furthermore, a plate-fin structure is provided between the heat storage module and the heat pipe, the heat storage module and the heat pipe form a heat conduction relationship through the plate-fin structure, and the heat storage module is made of phase change material.

[0021] By adopting the above solution, the plate-fin structure significantly increases the thermal conductivity between the heat pipe and the thermal storage module, that is, more heat can be quickly transferred to the thermal storage module, thereby improving the overall thermal conduction efficiency. The thermal storage module is made of phase change material, which can absorb a large amount of latent heat during the phase change process. When the heat pipe transfers heat to the thermal storage module, the phase change material can effectively store the heat and slow down the rate of temperature rise. The design of the plate-fin structure enables efficient heat conduction in a limited space while maintaining the compactness of the overall structure, thereby improving the heat dissipation performance without increasing the volume of the equipment.

[0022] Furthermore, it also includes copper foil, which is arranged around the outer surface of the shell, the outer surface of the heat storage module and the outer surface of the heat pipe, or the copper foil wraps the outer surface of the shell and is located between the heat pipe and the shell.

[0023] By adopting the above solution, the copper foil has excellent electromagnetic shielding performance, which can effectively reduce the impact of external electromagnetic interference on the X-ray tube and improve the stability and reliability of the equipment. In addition, due to the small thickness of the copper foil, due to contact and oxidation problems, its effective thermal conductivity range will be small. When the copper foil is used in combination with the heat pipe, it can be bent in an S-shaped manner at intervals within the effective thermal conductivity area of ​​the copper foil. This design makes the most of the efficient thermal conductivity of the copper foil, and can achieve the best heat dissipation effect even with a limited thermal conductivity area. It can maximize the efficient heat transfer capacity of the heat pipe and the high thermal conductivity of the copper foil, and the copper foil has a large surface area, so that the heat can be quickly dissipated to the environment.

[0024] Furthermore, a temperature sensor is provided in the thermal storage module.

[0025] By adopting the above solution, the cooling time is dynamically adjusted according to the temperature to minimize the waiting time of the user. At the same time, the use of phase change materials at the same ambient temperature can absorb more heat, thereby increasing the number of exposures per day and improving the user's usage efficiency.

[0026] Furthermore, the heat storage module is connected to a power generation component.

[0027] By adopting the above scheme, most of the energy (about 99%) is converted into heat energy in the X-ray tube. By setting up power generation components, the system can convert the originally wasted heat energy into useful electrical energy, significantly improving the overall energy utilization rate.

[0028] Furthermore, the insulating heat conductive part includes a first rod segment and a second rod segment, the diameter of the second rod segment is larger than the diameter of the first rod segment, the first rod segment is arranged through the shell, one end of the first rod segment is connected to the anode copper column, and the other end is connected to the second rod segment, the second rod segment is located on the side of the shell facing its outer surface, and the second rod segment is in contact with the heat pipe.

[0029] By adopting the above solution, the diameter of the second rod segment is larger than that of the first rod segment, that is, the contact area between the second rod segment and the heat pipe is larger. A larger contact area helps to improve the efficiency of heat transfer from the anode copper column to the heat pipe, thereby accelerating the heat dissipation. By passing the first rod segment through the shell and connecting it to the anode copper column, and the second rod segment is located on the outer surface of the shell and fits the heat pipe, an efficient heat conduction path is formed, thereby ensuring that heat can be quickly transferred from the anode copper column to the outside for heat dissipation.

[0030] Furthermore, the second rod section is sleeved with a sealing ring.

[0031] By adopting the above solution, the sealing ring can effectively prevent gas or liquid from leaking from the inside of the shell to the outside. When glue filling is required inside the shell, the setting of the sealing ring can also facilitate the glue filling process and ensure the airtightness of the shell during the glue filling process.

[0032] Furthermore, a third rod segment is provided between the second rod segment and the first rod segment, the first rod segment, the third rod segment and the second rod segment are connected in sequence, and the diameters of the first rod segment, the third rod segment and the second rod segment gradually increase.

[0033] By adopting the above scheme, as the diameters of the first rod segment, the third rod segment and the second rod segment gradually increase, the contact area between each rod segment and the adjacent components also gradually increases. The larger contact area helps to improve the efficiency of heat transfer from the anode copper column to the heat pipe, thereby accelerating the heat dissipation speed. And through the gradually increasing diameter design, an efficient heat conduction path is formed to ensure that heat can be quickly transferred from the anode copper column to the outside for heat dissipation, reducing thermal resistance. The insulating thermal conductor itself has good electrical insulation performance, and the gradually increasing diameter design further increases the creepage distance, enhances the electrical isolation effect, and prevents the occurrence of leakage.

[0034] Furthermore, an anode connecting wire metal sheet is sleeved on the insulating heat conductive member, and the anode connecting wire metal sheet is electrically connected to the anode copper column.

[0035] By adopting the above solution, the anode connecting wire metal sheet is directly electrically connected to the anode copper column, which ensures the stable transmission of current, reduces the contact resistance, and improves the reliability of the electrical connection.

[0036] In summary, the X-ray tube anode heat dissipation assembly provided by the present invention has the following technical effects:

[0037] 1. By using insulating heat conductors and heat pipes with high thermal conductivity, heat can be quickly transferred from the anode copper column to the heat storage module through the insulating heat conductors and heat pipes.

In addition, the efficient heat dissipation system can effectively prevent the anode from overheating and avoid the generation of evaporation caused by high temperature, thereby maintaining the vacuum degree in the tube and preventing discharge in the tube and melting of the anode target. This helps to extend the overall service life of the X-ray tube.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0050] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0053] See also Figure 1-Figure 3The present invention discloses an X-ray tube anode heat dissipation assembly, comprising an X-ray tube 1, an insulating heat conductive member 2, a heat storage module 3, a heat pipe 4 and a shell 5. The X-ray tube 1 comprises a glass shell 11 and an anode copper column 12. One end of the anode copper column 12 is located inside the glass shell 11 and the other end is located outside the glass shell 11. One end of the insulating heat conductive member 2 is connected to the anode copper column 12. The heat pipe 4 is respectively fitted with the insulating heat conductive member 2 and the heat storage module 3. A cavity 51 is provided inside the shell 5. The glass shell 11 and the anode copper column 12 are located in the cavity 51. The insulating heat conductive member 2 is arranged through the side wall of the shell 5. The portion of the insulating heat conductive member 2 located inside the shell 5 is connected to the anode copper column 12. The portion of the insulating heat conductive member 2 located outside the shell 5 is fitted with the heat pipe 4. The heat storage module 3 is used to store the heat transferred by the insulating heat conductive member 2 to the heat pipe 4.

[0054] Specifically, the X-ray tube 1 includes a glass shell 11 and an anode copper column 12. Of course, the X-ray tube 1 also includes other components for completing the X-ray emission function. Since the main points are no longer other components, they will not be described in detail here. One end of the anode copper column 12 is located in the glass shell 11, and the other end is connected to the insulating heat conductive member 2. The two ends of the heat pipe 4 are respectively connected to the insulating heat conductive member 2 and the heat storage module 3. The heat pipe 4 is made of materials with stable chemical properties and high thermal conductivity such as copper and aluminum. In this embodiment, the heat pipe 4 is made of copper, and the thermal conductivity of copper is 401W / mK, while the thermal conductivity of silicone rubber is between 0.8-1.5W / m·K. Combined with the structure of the heat pipe 4, the thermal conductivity of the copper heat pipe 4 is 5000W / mK. Compared with the thermal conductivity of silicone rubber, the thermal conductivity effect of the heat pipe 4 made of copper is 3333-6250 times that of silicone rubber. Therefore, compared with the prior art using silicone rubber for heat conduction, the copper heat pipe 4 has a better thermal conduction effect. The heat storage module 3 is in contact with the heat pipe 4 to receive the heat transferred by the heat pipe 4. A cavity 51 is provided inside the shell 5, and the glass shell 11 and the anode copper column 12 are both provided in the cavity 51. The insulating heat conductive member 2 is provided through the side wall of the shell 5, one end of which is connected to the anode copper column 12, and the other end is attached to the heat pipe 4, thereby completing the heat conduction from the inside of the shell 5 to the outside of the shell 5.

[0055] The heat conduction path of the above structure is: the heat generated by the anode copper column 12 is transferred to the heat pipe 4 through the insulating heat conductive part 2, and the heat pipe 4 can transfer it to the heat storage module 3 according to demand, or the heat pipe 4 transfers part of the heat to the heat storage module 3, and the other part of the heat is dissipated through the heat pipe 4.

[0056] The insulating heat-conducting member 2 can be made of a material such as alumina having a high thermal coefficient and insulating performance.

[0057] See also Figure 1-Figure 4In some embodiments, in order to increase the heat dissipation effect of the heat pipe 4, the heat pipe 4 includes a transition portion 41 and an extension portion 42, the transition portion 41 is connected with the extension portion 42, and the transition portion 41 is respectively attached to the insulating heat conductive member 2 and the heat storage module 3, so as to transfer part of the heat to the heat storage module 3, and the other part of the heat is dissipated through the heat pipe 4, so that when the heat to be dissipated is large and the duration is long, the overall temperature of the heat pipe 4 has reached a temperature close to that of the anode copper column 12, and the air temperature near the extension portion 42 of the heat pipe 4 is also close to the temperature of the heat pipe 4. When the heat dissipation efficiency of the heat pipe 4 is reduced, the heat storage module 3 can still effectively absorb heat, reducing the heat accumulation of the anode copper column 12 and significantly improving the heat dissipation efficiency. The extension portion 42 is arranged on the outer surface of the shell 5 in a winding shape. The extension portion 42 is arranged on the outer surface of the shell 5 in a winding shape, and its winding shape can be set according to actual needs, such as S-shaped, round-shaped, etc.

[0058] See also Figure 3 As shown, in some embodiments, in order to improve the heat exchange efficiency between the heat pipe 4 and the heat storage module 3, a plate-fin structure 31 is provided between the heat storage module 3 and the heat pipe 4, and the heat storage module 3 and the heat pipe 4 form a heat conduction relationship through the plate-fin structure 31, and the heat storage module 3 is made of phase change material.

[0059] Specifically, the plate-fin structure 31 significantly increases the thermal conductivity between the heat pipe 4 and the thermal storage module 3, that is, more heat can be quickly transferred to the thermal storage module 3, thereby improving the overall thermal conduction efficiency. The thermal storage module 3 is made of phase change material, which can absorb a large amount of latent heat during the phase change process. When the heat pipe 4 transfers heat to the thermal storage module 3, the phase change material can effectively store the heat and slow down the rate of temperature rise. The design of the plate-fin structure 31 enables efficient heat conduction in a limited space while maintaining the compactness of the overall structure, thereby improving the heat dissipation performance without increasing the volume of the equipment.

[0060] See also Figure 2 and Figure 3 As shown, in some embodiments, in order to improve the heat dissipation efficiency, the heat dissipation assembly also includes a copper foil 6, which is arranged around the outer surface of the shell 5, the outer surface of the heat storage module 3 and the outer surface of the heat pipe 4, or the copper foil 6 wraps the outer surface of the shell 5, and the copper foil 6 is located between the heat pipe 4 and the shell 5.

[0061] Specifically, in order to ensure the normal operation of the X-ray tube 1, a synchronous electromagnetic shielding function will be set outside the shell 5 to effectively reduce the impact of external electromagnetic interference on the X-ray tube 1, and shield the high-voltage electric field inside the X-ray source assembly to avoid damage to the external circuit and improve the stability and reliability of the equipment. On the basis of setting the copper foil 6, due to the small thickness of the copper foil 6, due to contact and oxidation problems, its effective thermal conductivity range will be small. When the copper foil 6 is used in combination with the heat pipe 4, it can be bent in an S-shaped manner at intervals within the effective thermal conductivity area of ​​the copper foil 6. This design makes the most of the efficient thermal conductivity of the copper foil 6, and can achieve the best heat dissipation effect even with a limited thermal conductivity area. It can also maximize the efficient heat transfer capacity of the heat pipe 4 and the high thermal conductivity of the copper foil 6, and the surface area of ​​the copper foil 6 is large, so that the heat can be quickly dissipated to the environment.

[0062] It should also be noted that in order to facilitate the display of the copper foil 6 and the internal components of the shell 5, one side of the copper foil 6 and the shell 5 is opened. During normal use, the copper foil 6 wraps the entire shell 5 as best. The shell 5 will also be sealed after the internal components are installed to ensure the stability of the internal components of the shell 5.

[0063] See also Figure 3 As shown, in some embodiments, when the heat storage module 3 is not connected to the heat pipe 4 for heat dissipation in real time, a temperature sensor 32 is provided in the heat storage module 3 for detecting the temperature of the heat storage module 3, so as to dynamically adjust the connection cooling time of the heat storage module 3 according to different temperatures, thereby reducing the waiting time of the user as much as possible. At the same time, the use of phase change materials at the same ambient temperature can absorb more heat, thereby increasing the number of exposures in a day and improving the user's usage efficiency.

[0064] It should be noted that, in other embodiments, the heat storage module 3 is normally connected to the heat pipe 4 during the heat dissipation process.

[0065] See also Figure 5 As shown, in some embodiments, in order to collect and convert the heat of the X-ray tube 1 , the heat storage module 3 is connected to a power generation component 8 .

[0066] Specifically, since most of the energy (about 99%) is converted into heat energy in the X-ray tube 1, by providing the power generation assembly 8, the system can convert the originally wasted heat energy into useful electrical energy, thereby significantly improving the overall energy utilization rate.

[0067] Among them, the power generation component 8 may include a thermocouple module, a hot side plate, a cold side plate, a radiator and a thermal interface material. The thermocouple module is usually composed of a plurality of P-type and N-type semiconductor materials arranged alternately to form a PN junction. When there is a temperature difference between the two ends of the PN junction, an electromotive force will be generated, thereby generating an electric current. The hot side plate is made of a metal material with a high thermal conductivity coefficient. The hot side plate is in contact with the heat storage module 3, absorbs heat and transfers it to the hot end of the thermocouple module. The cold side plate is also made of a metal material with a high thermal conductivity coefficient, so as to be in contact with a radiator or a cooling system, dissipate the heat of the cold end of the thermocouple module into the environment, and keep the cold end temperature low. The thermal interface material is used to fill the tiny gaps between the thermocouple module and the hot side plate and the cold side plate to improve the heat conduction efficiency.

[0068] The specific power generation principle is:

[0069] The thermocouple module is composed of alternating P-type and N-type semiconductor materials. When the hot side plate absorbs heat from the heat source (such as the thermal storage module 3) and transfers it to the hot end of the thermocouple module, the cold side plate dissipates the heat to the environment through the radiator to keep the cold end temperature low. This temperature difference generates an electromotive force in the thermocouple module, thereby generating current. The thermal interface material ensures good heat conduction between the thermocouple module and the hot side plate and the cold side plate, and the generated current is output to the external circuit through the wire for use by sensors, control systems or other low-power devices. The entire system has no moving parts, high reliability, and is suitable for heat recovery under low temperature conditions.

[0070] See also Figure 3 and Figure 6 As shown, in some embodiments, the insulating heat conductive member 2 includes a first rod segment 21 and a second rod segment 22, the diameter of the second rod segment 22 is larger than the diameter of the first rod segment 21, the first rod segment 21 is arranged through the shell 5, one end of the first rod segment 21 is connected to the anode copper column 12, and the other end is connected to the second rod segment 22, the second rod segment 22 is located on the side of the shell 5 facing its outer surface, and the second rod segment 22 is in contact with the heat pipe 4.

[0071] Specifically, since one end of the insulating heat conductive member 2 needs to be connected to the anode copper column 12, and the other end needs to be connected to the heat pipe 4, that is, the insulating heat conductive member 2 is connected to the anode copper column 12 at one end, in order to facilitate the sleeve connection of the anode connecting wire metal sheet 10 and occupy as little space as possible in the internal cavity 51 of the shell 5, the volume of the insulating heat conductive member 2 at this end should not be too large, that is, the diameter of the first rod segment 21 should not be too large. And the insulating heat conductive member 2 is in contact with the heat pipe 4 at one end, that is, the second rod segment 22. In order to ensure its heat exchange efficiency, the larger the diameter of the second rod segment 22, the higher the heat exchange efficiency. Based on this, the insulating heat conductive member 2 is designed by setting the first rod segment 21 and the second rod segment 22 with different diameters, so as to save the internal space of the shell 5 by passing the first rod segment 21 with a smaller diameter through the shell 5 and connecting it to the anode copper column 12, and the second rod segment 22 with a larger diameter is located on the outer surface of the shell 5 and fits the heat pipe 4, forming an efficient heat conduction path, thereby ensuring that heat can be quickly transferred from the anode copper column 12 to the outside for heat dissipation.

[0072] See also Figure 3 and Figure 6 As shown, further, due to the large difference in diameter between the first rod segment 21 and the second rod segment 22, in order to improve the heat conduction effect between the first rod segment 21 and the second rod segment 22, a third rod segment 23 is provided between the second rod segment 22 and the first rod segment 21, and the first rod segment 21, the third rod segment 23 and the second rod segment 22 are connected in sequence, and the diameters of the first rod segment 21, the third rod segment 23 and the second rod segment 22 are gradually increased.

[0073] Specifically, as the diameters of the first rod segment 21, the third rod segment 23, and the second rod segment 22 gradually increase, the contact area between each rod segment and the adjacent components also gradually increases. The larger contact area helps to improve the efficiency of heat transfer from the anode copper column 12 to the heat pipe 4, thereby accelerating the heat dissipation speed. And through the gradually increasing diameter design, an efficient heat conduction path is formed to ensure that heat can be quickly transferred from the anode copper column 12 to the outside for heat dissipation, reducing thermal resistance. The insulating heat conductor 2 itself has good electrical insulation performance, and the gradually increasing diameter design further increases the creepage distance, enhances the electrical isolation effect, and prevents the occurrence of leakage.

[0074] See also Figure 3 As shown, based on the structure that the insulating seal is divided into a first rod segment 21 and a second rod segment 22 , a sealing ring 9 is sleeved on the second rod segment 22 .

[0075] Specifically, the sealing ring 9 can effectively prevent gas or liquid from leaking from the inside of the shell 5 to the outside. When the inside of the shell 5 needs to be filled with glue, the setting of the sealing ring 9 can also facilitate the glue filling process. The sealing ring 9 can ensure the airtightness of the inside of the shell 5 during the glue filling process.

[0076] See also Figure 2 and Figure 3 As shown, in some embodiments, in order to improve the reliability of the electrical connection between the anode connecting wire metal sheet 10 and the anode copper column 12, the anode connecting wire metal sheet 10 is sleeved on the insulating thermal conductor 2, and the anode connecting wire metal sheet 10 is electrically connected to the anode copper column 12.

[0077] Specifically, the anode connecting wire metal sheet 10 is directly electrically connected to the anode copper column 12, thereby ensuring stable transmission of current, reducing contact resistance, and improving reliability of electrical connection.

[0078] In addition, as an option, thermal grease may be applied between any two adjacent heat-conducting components to improve the heat conduction effect.

[0079] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
