Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, and in particular to an X-ray tube anode heat dissipation assembly. Background Technology

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

[0003] Currently, the main heat dissipation method on the market is oil cooling. Oil cooling utilizes the fluidity of oil to quickly transfer heat from high-heat areas to low-heat areas. However, in order to ensure proper sealing of the insulating oil, it needs to be encased in a metal shell, resulting in a significant weight for the X-ray source assembly. In addition, oil cooling components also occupy a large amount of space. To reduce weight, some X-ray source assemblies use silicone rubber as the insulating medium and plastic as the outer shell. However, because silicone does not have fluidity, its heat dissipation efficiency is not as good as that of insulating oil. This can easily cause excessive heat accumulation at the anode, leading to abnormal operation of the X-ray tube. Furthermore, high temperatures can cause cracks and bubbles in the silicone, resulting in insulation failure and thus 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 that occur when using oil cooling for X-ray tube anodes.

[0005] The technical solution adopted by this invention to solve its problem is:

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

[0007] An X-ray tube, comprising a glass shell and an anode copper column, wherein 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 component, one end of which is connected to the anode copper pillar;

[0009] Thermal storage module;

[0010] A heat pipe, wherein the heat pipe is respectively attached to the insulating heat-conducting component and the heat storage module;

[0011] The housing has an internal cavity, in which the glass shell and the anode copper pillar are located. The insulating heat-conducting component is disposed through the side wall of the housing. The portion of the insulating heat-conducting component inside the housing is connected to the anode copper pillar, and the portion of the insulating heat-conducting component outside the housing is attached to the heat pipe.

[0012] The heat storage module is used to store the heat transferred by the heat pipe through the insulating heat-conducting component.

[0013] By employing the above-described scheme, and using insulating heat-conducting components and heat pipes with high thermal conductivity, heat can be rapidly transferred from the anode copper column to the heat storage module via these components. This structure significantly improves heat dissipation efficiency, reduces temperature accumulation in the anode region, thereby ensuring the stable operation of the X-ray tube. Furthermore, the efficient heat dissipation system effectively prevents anode overheating, avoiding the generation of evaporators due to high temperatures, thus maintaining the vacuum level within the tube and preventing internal discharge and anode target melting. This contributes to extending the overall service life of the X-ray tube.

[0014] The housing has an internal cavity that houses the glass shell and the anode copper pillar. An insulating heat-conducting component passes through the side wall of the housing and connects the anode copper pillar to an external heat pipe. Compared to oil cooling systems with more components, this application has a compact structure and efficient space utilization.

[0015] By using heat pipes and heat storage modules, the system can maintain stable heat dissipation performance over extended periods. Even under continuous operation for long periods, the anode temperature can be effectively controlled, ensuring reliable operation of the equipment.

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

[0017] In addition, insulating thermally conductive components are typically made of materials with high thermal conductivity, and they must also possess excellent electrical insulation properties to ensure electrical isolation between the anode copper pillar and the external structure. This can be achieved by selecting suitable insulating materials, which typically have high dielectric strength and voltage withstand characteristics.

[0018] Furthermore, the heat pipe includes a connector and an extension, the connector and the extension are connected, the connector is respectively attached to the insulating heat-conducting component and the heat storage module, and the extension is bent and disposed on the outer surface of the housing.

[0019] By adopting the above scheme, the extension is arranged in a bent state on the outer surface of the shell, which can increase the heat dissipation area, significantly improve the heat dissipation efficiency, reduce the heat accumulation of the anode copper column, and effectively control the temperature of the anode area by organically combining the heat pipe with the heat storage module, preventing overheating and thus 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, and the heat storage module and the heat pipe are thermally connected through the plate-fin structure. The heat storage module is made of phase change material.

[0021] By adopting the above scheme, the plate-fin structure significantly increases the thermal conductivity between the heat pipe and the heat storage module, meaning more heat can be quickly transferred to the heat storage module, thereby improving the overall heat transfer efficiency. The heat 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 heat storage module, the phase change material can effectively store this heat, slowing down the rate of temperature rise. The plate-fin structure design enables efficient heat transfer within a limited space while maintaining the compactness of the overall structure, thus improving heat dissipation performance without increasing the size of the device.

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

[0023] By adopting the above scheme, copper foil exhibits excellent electromagnetic shielding performance, effectively reducing the impact of external electromagnetic interference on the X-ray tube and improving the stability and reliability of the equipment. Furthermore, due to the thinness of the copper foil, contact and oxidation issues result in a relatively small effective heat conduction area. When used in conjunction with a heat pipe, the copper foil can be wound in an S-shaped pattern within its effective heat conduction area. This design maximizes the utilization of the copper foil's high thermal conductivity, achieving optimal heat dissipation even with a limited heat conduction area. It also maximizes the efficient heat transfer capacity of the heat pipe and the high thermal conductivity of the copper foil, and the large surface area of ​​the copper foil allows for rapid heat dissipation into the environment.

[0024] Furthermore, the heat storage module is equipped with a temperature sensor.

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

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

[0027] By adopting the above scheme, the vast majority of energy (approximately 99%) in the X-ray tube is converted into heat energy. By incorporating power generation components, the system can convert this previously wasted heat energy into usable electrical energy, significantly improving overall energy efficiency.

[0028] Furthermore, the insulating heat-conducting component includes a first rod segment and a second rod segment, the diameter of the second rod segment being larger than the diameter of the first rod segment, the first rod segment passing through the housing, one end of the first rod segment being connected to the anode copper pillar, and the other end being connected to the second rod segment, the second rod segment being located on the side of the housing facing its outer surface, and the second rod segment being in contact with the heat pipe.

[0029] By adopting the above scheme, the diameter of the second rod segment is larger than that of the first rod segment, meaning the contact area between the second rod segment and the heat pipe is larger. A larger contact area helps improve the efficiency of heat transfer from the anode copper pillar to the heat pipe, thereby accelerating heat dissipation. By having the first rod segment pass through the housing and connect to the anode copper pillar, and the second rod segment located on the outer surface of the housing and in contact with the heat pipe, a highly efficient heat conduction path is formed, ensuring that heat can be rapidly transferred from the anode copper pillar to the outside for dissipation.

[0030] Furthermore, the second rod segment is fitted 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 housing to the outside. When the inside of the housing needs to be potted, the sealing ring can also facilitate the potting process and ensure the airtightness of the inside of the housing during the potting process.

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

[0033] By adopting the above scheme, as the diameters of the first, third, and second rod segments gradually increase, the contact area between each rod segment and adjacent components also gradually increases. A larger contact area helps improve the efficiency of heat transfer from the anode copper pillar to the heat pipe, thereby accelerating heat dissipation. Furthermore, the gradually increasing diameter design creates an efficient heat conduction path, ensuring that heat can be quickly transferred from the anode copper pillar to the outside for dissipation, reducing thermal resistance. The insulating thermally conductive component itself has good electrical insulation properties, and the gradually increasing diameter design further increases the creepage distance, enhancing the electrical isolation effect and preventing leakage.

[0034] Furthermore, an anode connecting wire metal sheet is sleeved on the insulating heat-conducting component, and the anode connecting wire metal sheet is electrically connected to the anode copper pillar.

[0035] By adopting the above scheme, the metal sheet of the anode connecting wire is directly electrically connected to the anode copper column, which ensures stable current transmission, reduces 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-conducting components and heat pipes with high thermal conductivity, heat can be rapidly transferred from the anode copper pillar to the heat storage module via these components. This structure significantly improves heat dissipation efficiency, reduces temperature accumulation in the anode region, thereby ensuring stable operation of the X-ray tube. Furthermore, the efficient heat dissipation system effectively prevents anode overheating, avoiding the generation of evaporators due to high temperatures, thus maintaining the vacuum level inside the tube and preventing internal discharge and anode target melting. This helps extend the overall service life of the X-ray tube.

[0038] 2. The housing has an internal cavity that houses the glass shell and the anode copper pillar. An insulating heat-conducting component passes through the side wall of the housing and connects the anode copper pillar to an external heat pipe. Compared to oil cooling systems with more components, the structure of this application is compact and makes efficient use of space.

[0039] 3. By using heat pipes and heat storage modules, the system can maintain stable heat dissipation performance over a longer period of time. Even under long-term continuous operation, the anode temperature can be effectively controlled, ensuring reliable operation of the equipment.

[0040] 4. The heat storage module can be made of materials with high latent heat, which can always maintain a large temperature difference between it and the heat pipe, thereby ensuring heat transfer efficiency and effectively controlling the anode temperature even under long-term continuous operation.

[0041] 5. Insulating and thermally conductive components are typically made of materials with high thermal conductivity. They must also possess excellent electrical insulation properties to ensure electrical isolation between the anode copper pillar and the external structure. This can be achieved by selecting suitable insulating materials, which typically have high dielectric strength and voltage withstand characteristics. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0053] See Figures 1-3This invention discloses an X-ray tube anode heat dissipation assembly, including an X-ray tube 1, an insulating heat-conducting component 2, a heat storage module 3, a heat pipe 4, and a housing 5. The X-ray tube 1 includes a glass shell 11 and an anode copper pillar 12. One end of the anode copper pillar 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-conducting component 2 is connected to the anode copper pillar 12. The heat pipe 4 is attached to both the insulating heat-conducting component 2 and the heat storage module 3. The housing 5 has an internal cavity 51, within which the glass shell 11 and the anode copper pillar 12 are located. The insulating heat-conducting component 2 passes through the side wall of the housing 5. The portion of the insulating heat-conducting component 2 inside the housing 5 is connected to the anode copper pillar 12, and the portion of the insulating heat-conducting component 2 outside the housing 5 is attached to the heat pipe 4. The heat storage module 3 is used to store the heat transferred by the heat pipe 4 from the insulating heat-conducting component 2.

[0054] Specifically, the X-ray tube 1 includes a glass shell 11 and an anode copper column 12. The X-ray tube 1 also includes other components for X-ray emission, but since the focus is not on these components, they will not be detailed here. One end of the anode copper column 12 is located inside the glass shell 11, and the other end is connected to the insulating heat-conducting component 2. The two ends of the heat pipe 4 are connected to the insulating heat-conducting component 2 and the heat storage module 3, respectively. The heat pipe 4 is made of chemically stable materials with high thermal conductivity, such as copper or aluminum. In this embodiment, the heat pipe 4 is made of copper, which has a thermal conductivity of 401 W / mK. Silicone rubber has a thermal conductivity between 0.8 and 1.5 W / mK. Considering the structure of the heat pipe 4, the thermal conductivity of the copper heat pipe 4 is approximately 5000 W / mK. Compared to the thermal conductivity of silicone rubber, the thermal conductivity of the copper heat pipe 4 is 3333-6250 times that of silicone rubber. Therefore, compared to the existing technology using silicone rubber for heat conduction, the copper heat pipe 4 provides superior thermal conductivity. The heat storage module 3 is in contact with the heat pipe 4 to receive the heat transferred by the heat pipe 4. The housing 5 has a cavity 51 inside, and the glass shell 11 and the anode copper pillar 12 are both located in the cavity 51. The insulating heat-conducting element 2 is installed through the side wall of the housing 5, with one end connected to the anode copper pillar 12 and the other end attached to the heat pipe 4, thereby completing the heat conduction from the inside of the housing 5 to the outside of the housing 5.

[0055] The heat conduction path of the above structure is as follows: the heat generated by the anode copper column 12 is transferred to the heat pipe 4 through the insulating heat conduction component 2. The heat pipe 4 can transfer the heat to the heat storage module 3 as needed, or the heat pipe 4 can transfer part of the heat to the heat storage module 3 and the other part of the heat can be dissipated through the heat pipe 4.

[0056] Among them, the insulating and heat-conducting component 2 can be made of materials such as alumina that have high thermal coefficient and insulation performance.

[0057] See Figures 1-4In some embodiments, to enhance the heat dissipation effect of the heat pipe 4, the heat pipe 4 includes a connecting portion 41 and an extension portion 42, which are connected. The connecting portion 41 is respectively attached to the insulating heat-conducting component 2 and the heat storage module 3 to transfer a portion of the heat to the heat storage module 3, while the remaining heat is dissipated through the heat pipe 4. This ensures that when the amount of heat to be dissipated is large and the duration is long, the overall temperature of the heat pipe 4 reaches 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 also approaches the temperature of the heat pipe 4. Even when the heat dissipation efficiency of the heat pipe 4 decreases, 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 bent and disposed on the outer surface of the housing 5. The bending shape of the extension portion 42 on the outer surface of the housing 5 can be configured according to actual needs, such as S-shaped or U-shaped.

[0058] See 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. The heat storage module 3 and the heat pipe 4 form a thermally conductive relationship through the plate-fin structure 31. 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 heat storage module 3, meaning more heat can be quickly transferred to the heat storage module 3, thereby improving the overall heat transfer efficiency. The heat 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 heat storage module 3, the phase change material can effectively store this heat, slowing down the rate of temperature rise. The design of the plate-fin structure 31 enables efficient heat transfer within a limited space while maintaining the compactness of the overall structure, thus improving heat dissipation performance without increasing the size of the device.

[0060] See Figure 2 and Figure 3 As shown, in some embodiments, in order to improve heat dissipation efficiency, the heat dissipation component further includes a copper foil 6, which surrounds the outer surface of the housing 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 housing 5 and is located between the heat pipe 4 and the housing 5.

[0061] Specifically, to ensure the normal operation of the X-ray tube 1, a synchronous electromagnetic shielding function is installed outside the housing 5 to effectively reduce the impact of external electromagnetic interference on the X-ray tube 1, as well as shield the high-voltage electric field inside the X-ray source assembly, preventing damage to external circuits and improving the stability and reliability of the equipment. Based on the copper foil 6, due to its relatively small thickness and contact and oxidation issues, its effective heat conduction range is limited. When the copper foil 6 is used in conjunction with the heat pipe 4, it can be wound in an S-shaped pattern within the effective heat conduction area of ​​the copper foil 6. This design maximizes the efficient thermal conductivity of the copper foil 6, achieving optimal heat dissipation even with a limited heat conduction area. It also maximizes the efficient heat transfer capacity of the heat pipe 4 and the high thermal conductivity of the copper foil 6, and the large surface area of ​​the copper foil 6 allows for rapid heat dissipation into the environment.

[0062] Additionally, it should be noted that, in order to facilitate the display of the copper foil 6 and the internal components of the housing 5, one side of the copper foil 6 and the housing 5 is made open. During normal use, it is optimal for the copper foil 6 to completely cover the housing 5. The housing 5 will also be sealed after the internal components are installed to ensure the stability of the internal components of the housing 5.

[0063] See 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, the heat storage module 3 is equipped with a temperature sensor 32 to detect 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 the temperature, so as to minimize the waiting time of the user. At the same time, the use of phase change material can absorb more heat under the same ambient temperature, thereby increasing the number of exposures per 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 Figure 5 As shown, in some embodiments, the heat storage module 3 is connected to a power generation component 8 in order to collect and convert the heat of the X-ray tube 1.

[0066] Specifically, in X-ray tube 1, the vast majority of energy (approximately 99%) is converted into heat. By incorporating power generation component 8, the system can convert this wasted heat into usable electrical energy, significantly improving overall energy efficiency.

[0067] The power generation component 8 may include a thermocouple module, a hot side plate, a cold side plate, a heat sink, and a thermal interface material. The thermocouple module is typically composed of multiple alternating P-type and N-type semiconductor materials forming a PN junction. When a temperature difference exists between the two ends of the PN junction, an electromotive force is generated, thus producing a current. The hot side plate is made of a metal material with high thermal conductivity. It contacts the heat storage module 3, absorbing heat and transferring it to the hot junction of the thermocouple module. The cold side plate is also made of a metal material with high thermal conductivity and is used to contact the heat sink or cooling system, dissipating the heat from the cold junction of the thermocouple module into the environment and maintaining a low cold junction temperature. The thermal interface material is used to fill the tiny gaps between the thermocouple module and the hot and cold side plates, improving heat conduction efficiency.

[0068] The specific power generation principle is as follows:

[0069] The thermocouple module consists of alternating P-type and N-type semiconductor materials. When the hot side plate absorbs heat from a heat source (such as heat storage module 3) and transfers it to the hot junction of the thermocouple module, the cold side plate dissipates the heat to the environment through a heat sink, keeping the cold junction temperature low. This temperature difference generates an electromotive force in the thermocouple module, thus producing a current. The thermally conductive interface material ensures good thermal conductivity between the thermocouple module and the hot and cold side plates, while the generated current is output to an external circuit through wires 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 Figure 3 and Figure 6 As shown, in some embodiments, the insulating heat-conducting element 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 disposed through the housing 5. One end of the first rod segment 21 is connected to the anode copper pillar 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 housing 5 facing its outer surface and is in contact with the heat pipe 4.

[0071] Specifically, since one end of the insulating heat-conducting component 2 needs to be connected to the anode copper pillar 12 and the other end needs to be connected to the heat pipe 4, the volume of the insulating heat-conducting component 2 at the end connected to the anode copper pillar 12 should not be too large in order to facilitate the sleeve of the anode connecting wire metal piece 10 and to occupy as little space as possible in the internal cavity 51 of the housing 5. That is, the diameter of the first rod segment 21 should not be too large. On the other hand, the end of the insulating heat-conducting component 2 that contacts the heat pipe 4, namely the second rod segment 22, should have a larger diameter to ensure its heat exchange efficiency. Based on this, the insulating heat-conducting component 2 is designed with the first rod segment 21 and the second rod segment 22 having different diameters. This allows the smaller diameter first rod segment 21 to pass through the housing 5 and connect to the anode copper pillar 12, saving internal space in the housing 5. The larger diameter second rod segment 22 is located on the outer surface of the housing 5 and fits against the heat pipe 4, forming an efficient heat conduction path, thereby ensuring that heat can be quickly transferred from the anode copper pillar 12 to the outside for heat dissipation.

[0072] See Figure 3 and Figure 6 As shown, further, since there is a large diameter difference 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. 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 gradually increase.

[0073] Specifically, as the diameters of the first segment 21, the third segment 23, and the second segment 22 gradually increase, the contact area between each segment and adjacent components also gradually increases. A larger contact area helps improve the efficiency of heat transfer from the anode copper pillar 12 to the heat pipe 4, thereby accelerating heat dissipation. Furthermore, the gradually increasing diameter design creates an efficient heat conduction path, ensuring that heat can be quickly transferred from the anode copper pillar 12 to the outside for heat dissipation, reducing thermal resistance. The insulating thermally conductive component 2 itself has good electrical insulation properties, and the gradually increasing diameter design further increases the creepage distance, enhances the electrical isolation effect, and prevents leakage.

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

[0075] Specifically, the sealing ring 9 can effectively prevent gas or liquid from leaking from the inside of the housing 5 to the outside. When the inside of the housing 5 needs to be potted, the sealing ring 9 can also facilitate the potting process. The sealing ring 9 can ensure the airtightness of the inside of the housing 5 during the potting process.

[0076] See 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 pillar 12, the anode connecting wire metal sheet 10 is sleeved on the insulating heat-conducting component 2, and the anode connecting wire metal sheet 10 is electrically connected to the anode copper pillar 12.

[0077] Specifically, the anode connecting wire metal piece 10 is directly electrically connected to the anode copper pillar 12, which ensures stable current transmission, reduces contact resistance, and improves the reliability of the electrical connection.

[0078] Alternatively, thermal grease can be applied between any two adjacent thermally conductive components to improve thermal conductivity.

[0079] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
