Description

Technical Field

[0001] The present application belongs to the field of water-cooled magnet cooling, and more specifically, relates to a Bitter-type water-cooled magnet cooling structure and a Bitter-type water-cooled magnet. Background Art

[0002] Water-cooled magnets are commonly used in high-magnetic field laboratories. Due to their high magnetic field strength and fast field rise rate, they are often used in terahertz wave sources and X-ray diffraction experiments. Water-cooled magnets have high magnetic field strength, up to 40T or more, and consume tens of megawatts of power, which can generate a lot of heat. Water-cooled magnets use high-speed deionized cooling water to take away the heat to ensure that the magnet temperature is normal.

[0003] In the related art, a Bitter-type water-cooled magnet is a device that is composed of multiple Bitter-type water-cooled magnet coils and can generate a super-strong magnetic field through deionized water cooling. It is connected by an insulating disk, a multi-layer Bitter disk, and a positioning rod. The insulating disk and the Bitter disk are stacked alternately. The Bitter disk is covered with cooling holes and has slits. The size of the insulating sheet is usually a few to a dozen times the size of the Bitter sheet, and has cooling holes consistent with the Bitter. The insulating disk and the Bitter disk are aligned to form an axial cooling channel. Deionized cooling water can cool the Bitter-type water-cooled magnet through the cooling channel.

[0004] When the existing 140GHz terahertz gyrotron is used, the magnetic field strength at the resonant cavity is required to reach 5T. The Bitter-type water-cooled magnet can generate a large amount of heat. Deionized cooling water is used to flow from one end of the Bitter-type water-cooled magnet through a cooling channel to the other end to achieve cooling of the Bitter-type water-cooled magnet. However, when the deionized cooling water passes through the cooling channel, the distribution and flow rate of the deionized cooling water are uneven, which will lead to poor cooling effect of the Bitter-type water-cooled magnet, resulting in local overheating problems, thereby affecting the service life of the equipment. Summary of the invention

[0005] In response to the defects of the prior art, the present application provides a Bitter type water-cooled magnet cooling structure and a Bitter type water-cooled magnet, which aims to solve the problem that when deionized cooling water flows from one end of the Bitter type water-cooled magnet through a cooling channel to the other end, the cooling effect of the Bitter type water-cooled magnet is poor due to the uneven distribution and flow rate of the deionized cooling water.

[0006] A Bitter type water-cooled magnet cooling structure provided in the present application specifically includes a shell body, an upper flow guide and a lower flow guide; the upper flow guide and the lower flow guide are both arranged in the shell body and located on the same axis, and the water-cooled magnet body is placed between the upper flow guide and the lower flow guide; an upper end cover is arranged between the upper flow guide and the inner wall of the shell body, and a lower end cover is arranged between the lower flow guide and the inner wall of the shell body, a water inlet cavity is formed between the upper surface of the upper end cover and the inner wall of the shell body, and a water outlet cavity is formed between the lower surface of the lower end cover and the inner wall of the shell body, and a water inlet connected to the water inlet cavity and a water outlet connected to the water outlet cavity are provided on the shell body; a plurality of water inlet holes connecting the interior thereof with the water inlet cavity are arranged around the upper flow guide, and a plurality of water outlet holes connecting the interior thereof with the water outlet cavity are arranged around the lower flow guide, and the water inlet holes and the water outlet holes are connected through a cooling channel on the water-cooled magnet body.

[0007] The above technical scheme conceived by the present application is compared with the prior art. Since the cooling water of the present application enters the water inlet cavity from the water inlet, the cooling water in the water inlet cavity rises and then flows evenly into the interior of the upper guide member through the water inlet hole. The cooling water inside the upper guide member dissipates heat through the cooling channel on the water-cooled magnet body. After the cooling water enters the lower guide member, it enters the water outlet cavity through the water outlet hole and is then discharged from the water outlet. Since the cooling water can evenly pass through the cooling channel on the water-cooled magnet body and the cooling water flow rate in the cooling channel on the water-cooled magnet body is the same, the cooling water has the same heat dissipation effect on each part of the water-cooled magnet body, thereby achieving the beneficial effect of improving the heat dissipation effect and avoiding local overheating of the water-cooled magnet body.

[0008] As further preferred, the height of the water inlet is lower than the height of the water inlet hole.

[0009] By adopting the above technical solution, cooling water is injected from the water inlet, which can first make the water level in the water inlet chamber rise. When the water level rises to the height of the water inlet hole, the water in the water inlet chamber flows evenly to the inside of the upper guide member, so that the water in the upper guide member can pass through the cooling channel on the water-cooled magnet body evenly and at a uniform speed. The structure is simple, and the cooling water has a better heat dissipation effect on the water-cooled magnet body.

[0010] As a further preference, the water outlet hole is located at the side bottom of the lower flow guide member, and the water outlet is communicated with the side top of the water outlet cavity.

[0011] By adopting the above technical solution, the cooling water in the lower guide member flows out from the water outlet hole into the water outlet cavity, and can be discharged after the water level in the water outlet cavity rises to the water outlet, so that the flow rate of the cooling water flowing out of the lower guide member is uniform, further improving the heat dissipation effect of the cooling water on the water-cooled magnet body.

[0012] As a further preference, the cooling structure further comprises a central tube, wherein the central tube passes through the outer shell body and the water-cooled magnet body, and the central tube is a hollow structure.

[0013] By adopting the above technical solution, the setting of the central tube can make the position between the outer shell body and the water-cooled magnet body relatively fixed, improve the installation stability of the water-cooled magnet body, and make the cooling water in the upper guide member stably pass through the cooling channel on the water-cooled magnet body to achieve heat dissipation. At the same time, the central tube is a hollow structure, so that the gyrotube can pass through the middle of the central tube when used in this application.

[0014] As a further preference, the cooling structure further comprises two air cooling mechanisms for accelerating the flow of air outside the shell body, and the two air cooling mechanisms are respectively arranged at the water inlet and the water outlet.

[0015] By adopting the above technical solution, the air cooling mechanism drives the air flow outside the shell body, accelerates the heat dissipation on the shell body, and improves the heat dissipation effect of the water-cooled magnet body. The air cooling mechanism works through the flow of cooling water at the water inlet and outlet, and there is no need to set up an additional power mechanism, which saves energy and reduces the manufacturing cost of the device.

[0016] As a further preferred embodiment, the air cooling mechanism includes a guide box, which is fixedly connected to the water inlet or the water outlet, and the water inlet or the water outlet is connected to an external water source through the guide box. An impeller is rotatably connected inside the guide box, and the impeller is driven to rotate by water passing through the water inlet and the water outlet. Fan blades are also coaxially fixedly connected to the impeller and the fan blades are located outside the guide box.

[0017] By adopting the above technical solution, the cooling water at the water inlet and the water outlet flows through the guide box. The flow of cooling water in the guide box can realize the rotation of the impeller. The rotation of the impeller drives the fan blades to rotate, thereby realizing the air flow outside the outer shell body. The structure is simple and the implementation effect is good.

[0018] As a further preference, a heat sink communicating with the inside and the outside is arranged on the shell body, the heat sink is located between the upper end cover and the lower end cover, and the setting direction of the heat sink is the same as the air flow direction outside the shell body.

[0019] By adopting the above technical solution, the heat sink can quickly dissipate the heat inside the shell body, and drive the air flow through the fan blades to quickly dissipate the heat on the heat sink, which can effectively achieve the heat dissipation of the water-cooled magnet body.

[0020] The present application provides a Bitter-type water-cooled magnet, comprising a water-cooled magnet body and the above-mentioned cooling structure, wherein the water-cooled magnet body is arranged between an upper guide piece and a lower guide piece of the cooling structure, and the water-cooled magnet body comprises a water-cooled magnet coil, an upper end plate, a lower bottom plate and a plurality of threaded fixing rods, wherein the water-cooled magnet coil is arranged between the upper end plate and the lower bottom plate, and a plurality of threaded fixing rods surround the circumference of the water-cooled magnet coil, and the upper end plate and the lower bottom plate are fixed by threaded fixing rods.

[0021] By adopting the above technical solution, the upper end plate and the lower base plate are connected by a threaded fixing rod, so that the integrity of the water-cooled magnet body is better and the installation is more stable.

[0022] As a further preference, the cooling channel on the water-cooled magnet body is a straight channel or a curved channel.

[0023] By adopting the above technical solution, the cooling channel is set as a straight channel or a curved channel according to the heat generated by the water-cooled magnet body. When set as a straight channel, the cost is low and it is easy to assemble. When set as a curved channel, the path of cooling water flow can be increased, thereby improving the heat dissipation effect.

[0024] As a further preference, the upper end plate and the lower bottom plate are both provided with connection terminals, and two electrodes communicating the inside and the outside are fixedly connected to the shell body, and the two electrodes are electrically connected to the corresponding connection terminals respectively.

[0025] By adopting the above technical solution, it is convenient to connect the water-cooled magnet with external equipment through the wiring terminals and electrodes, thereby improving the connection stability.

[0026] In general, the above technical solutions conceived by this application have the following technical advantages compared with the prior art:

[0027] 1. The present application injects cooling water from the water inlet on the shell body, which can first make the water level in the water inlet cavity rise. When the water level rises to the height of the water inlet hole, the water in the water inlet cavity flows evenly toward the interior of the upper guide member, so that the water in the upper guide member can pass through the cooling channel on the water-cooled magnet body evenly and at a uniform speed. The cooling water dissipates heat through the cooling channel on the water-cooled magnet body. After the cooling water enters the lower guide member, it enters the water outlet cavity through the water outlet hole. When the water level in the water outlet cavity rises to the water outlet, it can be discharged, so that the flow rate of the cooling water flowing out of the lower guide member is uniform. Since the cooling water passes through the cooling channel evenly and the cooling water flow rate in the cooling channel on the water-cooled magnet body is the same, the cooling water has the same heat dissipation effect on each part of the water-cooled magnet body, which can improve the heat dissipation effect and avoid local overheating of the water-cooled magnet body.

[0035] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] Reference Figure 1-3 A Bitter type water-cooled magnet cooling structure disclosed in the present application includes a shell body 1, an upper guide member 2, a lower guide member 3 and a central tube 4; the shell body 1 is a cylindrical structure, and the top and bottom of the shell body 1 are connected by a sealing cover. After the internal structure is assembled, the sealing cover is used to seal the top and bottom, and the gap is sealed by glue filling.

[0037] In this embodiment, the upper guide piece 2 and the lower guide piece 3 are both annular structures, the upper guide piece 2 and the lower guide piece 3 are both fixedly connected to the inside of the shell body 1 and are located on the same axis, the upper guide piece 2 and the lower guide piece 3 are symmetrically arranged up and down, the water-cooled magnet body is arranged between the upper guide piece 2 and the lower guide piece 3 and is coaxially arranged with the upper guide piece 2 and the lower guide piece 3, the water-cooled magnet body is sealed and connected to the upper guide piece 2 and the lower guide piece 3, and the shell body 1 and the water-cooled magnet body are penetrated by the central tube 4, and the central tube 4 is connected to the central tube 4. The outer shell body 1 and the water-cooled magnet body are coaxially arranged, and the central tube 4 is a hollow structure. The arrangement of the central tube 4 can make the positions between the outer shell body 1 and the water-cooled magnet body relatively fixed, thereby improving the installation stability of the water-cooled magnet body. The top and bottom of the water-cooled magnet body are connected through a number of cooling channels. The cooling water in the upper guide member 2 stably dissipates heat through the cooling channels on the water-cooled magnet body. At the same time, the interior of the central tube 4 is in contact with the external air, and heat conduction and heat dissipation can be performed through the central tube 4, thereby enhancing the heat dissipation effect.

[0038] In this embodiment, an upper end cover 21 is fixedly connected between the upper flow guide 2 and the inner wall of the outer shell body 1, and a water inlet cavity is formed between the upper surface of the upper end cover 21 and the inner wall of the outer shell body 1, a lower end cover 31 is fixedly connected between the lower flow guide 3 and the inner wall of the outer shell body 1, and a water outlet cavity is formed between the lower surface of the lower end cover 31 and the inner wall of the outer shell body 1, and a water inlet 11 connected to the water inlet cavity and a water outlet 12 connected to the water outlet cavity are provided on the outer shell body 1, the water inlet 11 is a high-pressure water inlet, and the water outlet 12 is a low-pressure water outlet; a plurality of water inlet holes 22 connecting the water inlet cavity and its interior and having the same height are arranged around the top of the upper flow guide 2, and a plurality of water outlet holes 3 connecting the water outlet cavity and its interior and having the same height are arranged around the bottom of the lower flow guide 3 2. The water inlet hole 22 and the water outlet hole 32 are both round through holes. The water inlet hole 22 and the water outlet hole 32 are connected through the cooling channel on the water-cooled magnet body. When the cooling water enters the water inlet cavity from the water inlet port 11, the cooling water in the water inlet cavity rises and then flows evenly into the interior of the upper guide member 2 through multiple water inlet holes 22. The cooling water inside the upper guide member 2 realizes heat dissipation through the cooling channel on the water-cooled magnet body. After the cooling water enters the lower guide member 3, it enters the water outlet cavity through the water outlet hole 32 and is then discharged from the water outlet port 12. Since the cooling water can evenly pass through the cooling channel on the water-cooled magnet body and the cooling water flow rate in the cooling channel on the water-cooled magnet body is the same, the cooling water has the same heat dissipation effect on each part of the water-cooled magnet body, thereby improving the heat dissipation effect.

[0039] Specifically, the height of the water inlet 11 is lower than the height of the water inlet hole 22, the water outlet hole 32 is located at the side bottom of the lower guide member 3, and the water outlet 12 is connected to the side top of the water outlet cavity. When cooling water is injected from the water inlet 11, the water level in the water inlet cavity can be raised first. When the water level rises to the height of the water inlet hole 22, the water in the water inlet cavity flows evenly from the water inlet hole 22 to the inside of the upper guide member 2. At the same time, the cooling water in the lower guide member 3 flows out from the water outlet hole 32 into the water outlet cavity. When the water level in the water outlet cavity rises to the water outlet 12, it can be discharged. Since the distance between the water outlet hole 32 and the water outlet 12 is relatively far, the flow rate of the cooling water flowing out of the lower guide member 3 is uniform, further improving the heat dissipation effect of the cooling water on the water-cooled magnet body.

[0040] Furthermore, the cooling structure further includes two air cooling mechanisms 5, through which the air flow outside the housing body 1 is accelerated, and the two air cooling mechanisms 5 are respectively arranged at the water inlet 11 and the water outlet 12. When the water at the water inlet 11 and the water outlet 12 flows, the air cooling mechanisms 5 can be driven to work. Specifically, the air cooling mechanism 5 includes a guide box 51, which is fixedly connected to the water inlet 11 or the water outlet 12. The water inlet 11 and the water outlet 12 are respectively connected to an external cooling water source (water cooling water source) through the guide box 51. The impeller 52 is connected to the water inlet 11 and the water outlet 12, and the impeller 52 is driven to rotate by water. The cooling water source passes through the guide box 51 and enters the water inlet 11. The impeller 52 is rotated under the impact of the water flow. The impeller 52 is coaxially fixed with a fan blade 53, and the fan blade 53 is located outside the guide box 51. The impeller 52 drives the fan blade 53 to rotate to make the air flow. Similarly, the cooling water discharged from the water outlet 12 passes through the guide box 51 to rotate the impeller 52, and then the fan blade 53 rotates.

[0041] Furthermore, a heat sink 6 connecting the inside and the outside is fixedly connected to the shell body 1, and the heat sink 6 is located between the upper end cover 21 and the lower end cover 31. The setting direction of the heat sink 6 is the same as the direction of air flow outside the shell body 1. The heat sink 6 is made of non-magnetic and non-conductive material, and a ceramic heat sink 6 or a graphite heat sink 6 can be used. The heat sink 6 can quickly dissipate the heat inside the shell body 1, and the air flow is driven by the fan blades 53 to quickly dissipate the heat on the heat sink 6, which can effectively realize the heat dissipation of the water-cooled magnet body.

[0042] The present application also discloses a Bitter type water-cooled magnet, comprising a water-cooled magnet body and the above-mentioned cooling structure, wherein the water-cooled magnet body is arranged between the upper guide piece 2 and the lower guide piece 3 of the cooling structure, wherein the water-cooled magnet body comprises a water-cooled magnet coil 7, an upper end plate 71, a lower bottom plate 72 and a plurality of threaded fixing rods 73, wherein the upper end plate 71 and the lower bottom plate 72 are both made of metal materials, wherein the water-cooled magnet coil 7 is composed of an insulating sheet and a Bitter disk, wherein the Bitter disk and the insulating sheet are covered with radially staggered cooling holes and have a slit, wherein the insulating sheets and Bitter disks having the same cooling hole distribution are alternately stacked and connected by insulating rods with threads at both ends, wherein the insulating rods are made of pee k is made of high-strength insulating material. After the insulating rod passes through the insulating sheet and the Bitter disk, the two ends are connected by nuts and gaskets, so that the water-cooled magnet body forms an axial cooling channel. The outside of the water-cooled magnet coil 7 is also sleeved. The sleeve is at the same height as the water-cooled magnet coil 7 and is tightly connected to the outside of the water-cooled magnet coil 7. The sleeve can cooperate with the center tube 4 to achieve positioning and prevent cooling water from flowing to the outside of the water-cooled magnet coil 7, that is, the cavity between the water-cooled magnet coil 7 and the shell body 1. The water-cooled magnet coil 7 is a common device in this field and is not specifically introduced in this embodiment. The water-cooled magnet coil 7 is fixedly installed between the upper end plate 71 and the lower bottom plate 72, so that the insulating sheet and the Bitter disk fit tightly. The overpressure is tightened to make full contact between the disks to prevent electrical short circuit. Several threaded fixing rods 73 surround the peripheral side of the water-cooled magnet coil 7, and the upper end plate 71 and the lower bottom plate 72 are fixed by threaded fixing rods 73. The threaded fixing rods 73 are made of peek high-strength insulating material. Specifically, four threaded fixing rods 73 are provided, and four integrally formed connecting terminals are evenly arranged around the upper end plate 71 and the lower bottom plate 72. The threaded fixing rods 73 are connected to the corresponding connecting terminals to fix and support the water-cooled magnet body. The threaded fixing rods 73 pass through the corresponding connecting terminals of the upper end plate 71 and the lower bottom plate 72, and the upper end cover 21 and the lower end cover 31 are provided with through holes for the threaded fixing rods 73 to pass through. , bolts are used to fix the two ends of the threaded fixing rod 73, so that the water-cooled magnet body can be stably installed between the upper guide member 2 and the lower guide member 3, and cooling holes 711 connected to the cooling channel on the water-cooled magnet coil 7 are provided on the upper end plate 71 and the lower bottom plate 72 to form a cooling channel on the water-cooled magnet body as a whole. In order to facilitate the connection of the water-cooled magnet coil 7 with external equipment, the upper end plate 71 and the lower bottom plate 72 are provided with integrally formed wiring terminals 712, and two electrodes (not shown in the figure) connecting the inside and the outside are fixedly connected to the outer wall of the shell body 1, and the two wiring terminals 712 are electrically connected to the two electrodes respectively, and the wiring terminals 712 have small slits to allow current to flow in a spiral path.

[0043] Furthermore, the cooling holes 711 constitute a cooling channel to form a straight channel or a curved channel. The cooling channel is set to a straight channel or a curved channel according to the heat that the water-cooled magnet body can generate. When set to a straight channel, the cost is low and the assembly is convenient. When set to a curved channel, the path of the cooling water flow can be increased, thereby improving the heat dissipation effect.
