Description

Technical Field

[0001] This utility model relates to the technical field of high voltage vacuum devices, specifically a transmission target ray tube with a heat dissipation structure. Background Technology

[0002] A transmission target X-ray tube is a type of X-ray tube whose core structure is a transmission target material. An electron beam strikes the target surface perpendicularly to generate X-rays. The transmission target X-ray tube involved in this utility model belongs to the core type of open microfocus X-ray tube. Open microfocus X-ray tubes are widely used in fields such as electronic chip detection, material analysis, and medical microscopic imaging due to their small focal spot and high resolution.

[0003] However, the current mainstream heat dissipation solution is to install an external cooling jacket on the outer pole shoe surrounding the focusing component, using either water or air cooling. This solution involves winding the focusing coil onto an insulating frame, typically a monolithic structure, which is then fitted onto the inner pole shoe. After encapsulation, cooling channels are machined into the outermost pole shoe shell or a cooling jacket is installed, allowing the cooling medium to flow externally and attempt to remove heat from the outer pole shoe surface. However, this approach suffers from poor heat dissipation performance.

[0004] Therefore, this invention provides a transmission target ray tube with a heat dissipation structure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a transmission target ray tube with a heat dissipation structure to solve the problem mentioned in the background art: the current mainstream heat dissipation solution involves installing an external cooling sleeve on the outer pole shoe surrounding the focusing assembly, using water cooling or air cooling. The implementation of this solution is as follows: the focusing coil is wound on an insulating frame, which is usually an integral structure, fitted onto the inner pole shoe. After encapsulation, cooling channels are machined or a cooling sleeve is installed on the outermost pole shoe shell, with the cooling medium flowing externally in an attempt to remove heat from the surface of the outer pole shoe, resulting in poor heat dissipation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transmission target ray tube with a heat dissipation structure, comprising a mounting tube shell, a bottom cover plate, a top cover plate, and an inner pole shoe;

[0007] Also includes:

[0008] The mounting tube housing is equipped with a skeleton assembly, which includes an intermediate cylinder inside the mounting tube housing, a mounting base plate at the lower end of the intermediate cylinder, and an upper cover plate at the upper end of the intermediate cylinder. The intermediate cylinder is a hollow cylindrical structure, with its inner wall fitted to the outer surface of the inner pole shoe, and its outer wall used for winding the enameled wire of the focusing coil.

[0009] The frame assembly has a perforated groove structure for water cooling.

[0010] Preferably, the bottom cover is snapped into and sealed at the lower end of the mounting tube shell, and the bottom cover and the mounting tube shell are limited by a plurality of first bolts passing through the edge of the bottom cover.

[0011] Preferably, the top cover is snapped and sealed onto the upper end of the mounting housing, and the top cover and the mounting housing are limited by a plurality of second bolts passing through the edge of the top cover.

[0012] Preferably, the upper end of the top cover plate is provided with a transmission target assembly, and the upper end of the transmission target assembly is fitted with an auxiliary cover plate, and the transmission target assembly and the auxiliary cover plate are limited by a number of third bolts provided on the outside of the transmission target assembly.

[0013] Preferably, a mounting base plate is welded to the bottom of the intermediate cylinder, and the mounting base plate has mounting holes for mounting the focusing coil.

[0014] Preferably, an upper cover plate is welded to the upper end of the intermediate cylinder, and a connection port is provided on the upper cover plate. The connection port is connected to a cooling channel provided on the side wall of the intermediate cylinder, and a water outlet is provided above the connection port for connecting a cooling water pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The heat generated by the focusing coil during the operation of this transmission target X-ray tube with heat dissipation structure is first conducted to the focusing coil skeleton through the wire and insulation layer. The coolant of the external water cooling system inside the coil skeleton directly carries away the heat, avoiding heat accumulation and establishing an efficient direct liquid cooling path. The heat is "drawn out" through the high thermal conductivity focusing coil skeleton, shortening the heat dissipation path, greatly reducing thermal resistance, and quickly carrying away the heat. The heat dissipation efficiency is extremely high, the cooling effect is significant, and the magnetic field stability and focus stability are greatly improved, indirectly improving the performance of the X-ray tube. The structure is compact and reliable. The heat dissipation structure is integrated inside the coil skeleton without adding extra volume. The structure is compact and highly reliable. It changes the traditional idea of ​​"cooling from the outside to the inside" and innovatively proposes the concept of "embedded heat dissipation directly from the center of the heat source". It shortens the heat dissipation path and greatly reduces thermal resistance. Actual measurements show that the stable working temperature inside the focusing coil can be significantly reduced from the existing 95℃ to about 40℃, and the temperature fluctuation is less than ±1 degree.

[0016] 1. It is equipped with an installation tube shell, a bottom cover plate, and a top cover plate. The installation tube shell and the bottom cover plate are connected by a first bolt after being engaged, and the installation tube shell and the top cover plate are connected by a second bolt after being engaged. The structure is compact and reliable, without increasing the overall volume.

[0017] 2. It is equipped with a skeleton assembly, which includes an intermediate cylinder, a mounting base plate and an upper cover plate. The wires and insulation layer are conducted to the focusing coil skeleton, establishing an efficient direct liquid cooling path to quickly remove heat and achieve good heat dissipation.

[0018] 3. It is equipped with a slotted structure, which is opened on the frame and includes a connection port and a cooling channel. At the same time, there is a water outlet above the connection port for connecting the cooling water pipe and for water injection cooling, so as to quickly remove heat and achieve efficient heat dissipation.

[0026] Please see Figures 1-5 The present invention provides the following technical solution:

[0027] To address the current mainstream heat dissipation solutions, the main approach is to install an external cooling jacket, either water-cooled or air-cooled, on the outer pole shoe surrounding the focusing component. The implementation of this solution is as follows: the focusing coil is wound on an insulating frame, which is usually an integral structure, fitted onto the inner pole shoe 9. After encapsulation, a cooling channel is machined or a cooling sleeve is installed on the outermost outer pole shoe shell. The cooling medium flows on the outside, attempting to remove heat from the surface of the outer pole shoe. However, the heat dissipation effect is not good. Therefore, this solution addresses the problem of poor heat dissipation by providing a transmission target ray tube with a heat dissipation structure. The tube is equipped with a mounting shell 1, a bottom cover plate 2, a top cover plate 3, and an inner pole shoe 9. The mounting shell 1 is equipped with a frame assembly, which includes an intermediate cylinder 10 inside the mounting shell 1, a mounting base plate 11 at the lower end of the intermediate cylinder 10, and an upper cover plate 13 at the upper end of the intermediate cylinder 10. The mounting base plate 11 has mounting holes 12 for mounting the focusing coil. The intermediate cylinder 10 is a hollow cylindrical structure, with its inner wall fitted to the outer surface of the inner pole shoe 9. Its outer wall is used to wind the enameled wire of the focusing coil. The frame assembly has slotted structures for water cooling.

The second bolt 5 connects and limits the top cover plate 3 to the mounting shell 1. Simultaneously, a transmission target assembly 6 is provided at the upper end of the top cover plate 3, increasing the heat dissipation area. An auxiliary cover plate 7 is snapped onto the upper end of the transmission target assembly 6. The transmission target assembly 6 and the auxiliary cover plate 7 are limited by a third bolt 8. The skeleton assembly is located inside the mounting shell 1 and consists of an intermediate cylinder 10, a mounting base plate 11, and an upper cover plate 13. Figure 4 and Figure 5 As shown, an upper cover plate 13 is provided on the mounting base plate 11 for subsequent installation of the focusing coil. The intermediate cylinder 10 is connected to the mounting base plate 11 and the upper cover plate 13 by welding to ensure no water leakage. The upper cover plate 13 is provided with a connection port 14, which is connected to the cooling channel 15 provided on the side wall of the intermediate cylinder 10. At the same time, there is a water outlet above the connection port 14 for connecting the cooling water pipe. The connection port 14 is divided into an inlet and an outlet. The inlet, the cooling channel 15 and the outlet form a heat dissipation path, and the coolant directly carries away the heat to avoid heat accumulation.
