Description

Technical Field

[0001] This utility model belongs to the field of X-ray tube high-voltage cable connection technology, specifically relating to a high-voltage socket with a cooling channel and an X-ray generator. Background Technology

[0002] A high-voltage socket and a high-voltage cable plug work together to introduce high voltage from a high-voltage generator into the X-ray tube. The high-voltage socket includes an insulated socket body, and an X-ray source component or X-ray source and / or heating component, such as an X-ray generating element, a cathode component, or an anode component, arranged on the vacuum side of the socket body. This component can generate heat during the operation of the X-ray source, which may cause deterioration of the X-ray source components and / or parts, reduce the power of the X-ray tube, overheat, or even cause the X-ray tube to fail.

[0003] US20100111265A1 discloses a method for setting a cooling channel in the socket body or other additional structures. In actual use, the outlet and inlet positions of the cooling pipes in this method will interfere with the connection components of the high-voltage cable plug. Even if the connection components of the high-voltage cable plug are modified, there are still problems such as high difficulty, high cost, lack of practicality and universality. Moreover, the outlet and inlet positions are difficult to seal, which easily leads to the risk of leakage. Therefore, it is necessary to optimize the way the coolant is introduced and led out.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0035] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0036] High-voltage socket 1 in the prior art Figure 1 As shown, the socket body 2 is approximately cylindrical and typically does not contain a cooling channel, making anode heat dissipation difficult. If a cooling channel for cooling the anode is provided inside the socket body 2, as shown in patent US20100111265A1, the arrangement of the inlet and outlet of the cooling channel is not practical. The inlet and outlet are prone to interference with the installation components of the high-voltage cable plug, or make it difficult to seal the inlet and outlet. In practice, this is difficult and has poor feasibility.

[0037] Therefore, in view of the technical problems existing in the prior art, this utility model proposes a high-voltage socket 100 with a cooling channel.

[0038] The following is combined Figures 2 to 3 The high-voltage socket 100 with cooling channel provided by the present invention will be described in detail through specific embodiments and application scenarios.

[0039] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0040] A high-voltage socket 100 with a cooling channel according to an embodiment of the present invention is used to mate with a high-voltage cable plug. The high-voltage socket 100 with a cooling channel includes a socket body 10 and an anode (not shown).

[0041] like Figure 2 As shown, the socket body 10 is formed as an approximately columnar insulating member. A flow guide 30 extends circumferentially from one end of the socket body 10. The socket body 10 defines a receiving cavity extending axially and open at one end for accommodating a high-voltage cable plug. The socket body 10 defines a cooling channel 11. The flow guide 30 defines an inlet hole 31 and an outlet hole 32 communicating with the cooling channel 11. Coolant is introduced into the cooling channel 11 through the inlet hole 31 and discharged from the cooling channel 11 through the outlet hole 32. The anode is located at the other end of the socket body 10 and communicates with the cooling channel 11 to be cooled by the coolant.

[0042] Specifically, according to an embodiment of the present invention, a high-voltage socket 100 with a cooling channel has a cooling channel 11 inside the socket body 10. The cooling channel 11 is connected to the anode at the anode end to provide coolant to the anode. Simultaneously, a guide portion 30 is provided at one end of the socket body 10, which is equivalent to increasing the outer diameter of one end of the high-voltage socket. The axial cross-section of the high-voltage socket resembles a "T" shape. To introduce or drain the coolant (e.g., insulating cooling oil) from the high-voltage socket, an inlet hole 31 and an outlet hole 32 are provided in the guide portion 30. The inlet hole 31 and the outlet hole 32 are respectively connected to the cooling channel 11, thereby changing the flow direction of the coolant. Figure 2 As shown, the inlet of the liquid inlet 31 and the outlet of the liquid outlet 32 ​​can be respectively located in the circumferential direction of the guide portion 30, or located below or inclined below the guide portion 30 away from the socket body 10, thereby avoiding interference with the mounting components of the high-voltage cable plug and facilitating the introduction or exit of coolant into or out of the high-voltage socket. Figure 2 As shown, the socket body 10 may have a small diameter section below the flow guide 30 to facilitate assembly with the flange.

[0043] Therefore, the high-pressure socket 100 with a cooling channel according to the present utility model embodiment, by providing a flow guide 30 at the other end of the socket body 10, and providing an inlet hole 31 and an outlet hole 32 in the flow guide 30, not only facilitates the entry and exit of coolant in the socket body 10, but also facilitates sealing and installation, and has feasibility and versatility.

[0044] According to one embodiment of the present invention, the high-voltage socket 100 with a cooling channel further includes a drain pipe 40, which is disposed at the other end of the socket body 10 to connect the cooling channel 11 and the anode.

[0045] Specifically, such as Figure 2 As shown, a conductive electrode 20 is provided on the inner wall of the other end of the socket body 10. The conductive electrode 20 is connected to the anode to achieve electrical conduction. If the cooling channel 11 on the socket body 10 is directly connected to the anode, the structure of the anode or the structure of the socket body 10 needs to be further improved. To avoid making too many modifications to the anode structure or the structure of the socket body 10, a drainage tube 40 is installed here, such as... Figure 2 As shown, at least two drain pipes 40 need to be installed. The drain pipes 40 connect the anode and the cooling channel 11. One drain pipe 40 introduces the coolant in the cooling channel 11 into the anode, and the other drain pipe 40 introduces the coolant in the anode into the cooling channel 11, thus completing the circulation of coolant in the anode and heat dissipation of the anode.

[0046] Preferably, the socket body 10 is a one-piece molded part, and the liquid inlet 31 and liquid outlet 32 ​​extend along a direction perpendicular to the central axis of the socket body 10. For example... Figure 2 As shown, the one-piece molded part has a stable structure and is easy to process and form. The cooling channel 11 and the liquid inlet hole 31 or liquid outlet hole 32 transition naturally without the need for additional sealing.

[0047] According to one embodiment of the present invention, the socket body 10 includes a first mating part 12 and a second mating part 13.

[0048] Specifically, the first mating portion 12 is formed as a columnar insulating member, and a first flow guide portion 30 extends circumferentially from one end of the first mating portion 12, and a receiving cavity is defined within the first mating portion 12; the second mating portion 13 is formed as a columnar insulating member, and a second flow guide portion extends circumferentially from one end of the second mating portion 13, and the second flow guide portion mates with the first flow guide portion to form the flow guide portion 30; a mating cavity extending axially is defined within the second mating portion 13, and the mating cavity is used to receive the first mating portion 12; at least one of the outer wall surface of the first mating portion 12 and the inner wall surface of the second mating portion 13 has a groove, and the groove defines a cooling channel 11 when the first mating portion 12 is located within the mating cavity.

[0049] In other words, the socket body 10 consists of two separate parts, such as Figure 3 As shown, specifically, there can be multiple combinations. For example, the outer wall surface of the first mating part 12 defines a groove. When the second mating part 13 is fitted onto the first mating part 12, the groove of the first mating part 12 and the inner wall surface of the second mating part 13 form a cooling channel 11. Alternatively, the inner wall surface of the second mating part 13 defines a groove. When the second mating part 13 is fitted onto the first mating part 12, the groove on the second mating part 13 and the outer wall surface of the first mating part 12 form a cooling channel 11. When both the outer wall surface of the first mating part 12 and the inner wall surface of the second mating part 13 are provided with grooves, the two grooves should be arranged opposite each other to form a cooling channel 11. The split-type socket body 10 structure facilitates the processing of grooves and the formation of cooling channels 11. Optionally, as... Figure 3 As shown, the inlet and outlet are respectively located in the second guide section.

[0050] For the split-type socket body 10, the second mating part 13 defines a drainage hole 131 that connects the cooling channel 11 and the drainage pipe 40. For example... Figure 3 As shown, it should be noted that a sealing ring 80 should be provided at the connection between the drainage hole 131 and the first mating part 12 to prevent coolant leakage.

[0051] Furthermore, the inlet hole 31 and the outlet hole 32 extend in a direction parallel to the central axis of the socket body 10. For the split-type socket body 10, positioning the inlet hole 31 and the outlet hole 32 in the axial direction of the first mating part 12 facilitates the connection between the inlet hole 31 and the outlet hole 32 and the cooling channel 11. A sealing ring 80 should also be provided at the connection to prevent coolant leakage. In addition, a liquid storage tank 121 can be provided in the circumferential direction of the first mating part 12. The liquid storage tank 121 is connected to the inlet hole 31 or the outlet hole 32 to store coolant and play a buffering role.

[0052] Optionally, the cooling channel 11 is formed in a spiral and / or straight shape. Specifically, the cooling channel 11 may adopt a straight structure, a spiral structure, or a combination of straight and spiral shapes, and is not limited thereto.

[0053] According to another embodiment of the present invention, an extension portion 50 extends circumferentially from one end of the socket body 10. The extension portion 50 is located on the side of the guide portion 30 facing the anode and is connected to the guide portion 30. The high-voltage socket 100 with a cooling channel also includes a first electrode ring 70 and a second electrode ring 60. Specifically, the first electrode ring 70 is connected to the other end of the socket body 10 to connect to the anode, and the first electrode ring 70 is used to connect to the high-voltage end of the high-voltage cable plug; the second electrode ring 60 is sleeved on the outer periphery of the extension portion 50 and the inner wall surface of the second electrode ring 60 is connected to the outer periphery of the extension portion 50, and the second electrode ring 60 is used to connect to the ground end of the high-voltage cable plug.

[0054] Specifically, the axial cross-section of the socket body 1 in the prior art is as follows: Figure 1 As shown, the socket body 2 has a cylindrical structure. When a high voltage cable plug is connected to a high voltage source, the electric field strength at the connection point between the second electrode ring 3 and the socket body 2 is relatively large, which can easily lead to arcing or breakdown. Currently, there is no good shielding method. In response to this, as... Figure 2 and Figure 3 As shown, in this embodiment of the utility model, an extension 50 is provided in the circumferential direction of the socket body 10. The extension 50 is located at the upper end of the current guiding part 30, so that the axial cross-section of the socket body 10 is similar to a trumpet shape. The second electrode ring 60 is sleeved on the extension 50. Compared with the prior art, the distance between the connection point of the second electrode ring 60 and the extension 50 and the high-voltage cable plug is farther, which reduces the electric field strength at the connection point and increases the length of the outer edge surface between the two ends of the socket body 10, thereby improving the insulation performance and safety of the socket body 10.

[0055] Preferably, an annular gap 61 is defined between the outer periphery of the extension 50 facing the anode and the second electrode ring 60, that is, a deep groove structure is formed between the second electrode ring 60 and the extension 50, which helps to further improve the insulation performance of the high-voltage socket.

[0056] The X-ray generator according to the second aspect of the present invention includes the high-voltage socket 100 with a cooling channel as described in the above embodiment. Since the high-voltage socket 100 with a cooling channel according to the present invention not only has the function of cooling the anode, but is also easy to assemble and seal, and has practicality and versatility, the X-ray generator according to the present invention also has the above advantages.

[0057] Other structures and techniques of the X-ray generator according to the embodiments of this utility model are prior art and will not be described in detail here.

[0058] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
