A heat dissipation device for high-power plasma structure

Abstract

The present invention discloses a heat dissipation device for a high-power plasma structure, comprising an ionization chamber and heat dissipation components arranged on the front and rear sides of the ionization chamber. The present invention relates to the technical field of plasma generators. The heat dissipation device for a high-power plasma structure utilizes an inner spiral gas guide pipe as an airway to increase the gas residence time while driving the inner spiral gas guide pipe to rotate. In conjunction with the arrangement of a first water channel, a second water channel, and a third water channel, the rotation of the inner spiral gas guide pipe is accelerated when cooling water passes through at high speed. The centrifugal force generated by the rotation increases the core density of the gas, the frequency of electron-molecule collisions, and the ionization efficiency. The inner spiral gas guide pipe is placed in the second water channel, and heat is dissipated during the rotation of the inner spiral gas guide pipe, effectively improving the heat dissipation efficiency of the ionization chamber and providing efficient and reliable protection for the long-term stable use of the equipment.

Description

Technical Field

[0001] The present invention relates to the technical field of plasma generators, in particular to a heat dissipation device for a high-power plasma structure. Background Art

[0002] When exposed to high temperatures or strong electromagnetic fields, gases can become plasma, the fourth state of matter after solid, liquid, and gas. In this state, the atoms in the gas have more or fewer electrons than normal, forming anions or cations—negatively or positively charged particles. Any covalent bonds in the gas also break down.

[0003] The plasma generator increases the low voltage to positive high voltage and negative high voltage through the boost circuit, and uses the positive high voltage and negative high voltage to ionize the air to produce a large number of positive ions and negative ions, so that the number of negative ions is greater than the number of positive ions. During its operation, it is easy to cause problems such as overheating of the magnetic core and uneven heat dissipation of the cavity. If the temperature of the magnetic core exceeds the critical point, it will cause demagnetization and burning.

[0004] For example, a remote plasma generator described in publication number CN116390317B uses an external heat dissipation device in conjunction with a cooling water channel in the ionization chamber to achieve synchronous heat exchange inside and outside, thereby improving heat dissipation efficiency, extending the service life of the chamber and seals, and improving production efficiency. However, when it is working, air passes directly through the air cavity, the gas residence time is short, and the ion state conversion efficiency is low. In addition, when the existing technology uses a built-in cooling water channel to dissipate heat from the ionization chamber, only the cooling water channel is added, and there is still a defect that the heat dissipation efficiency is not ideal.

[0005] In view of this, a heat dissipation device for a high-power plasma structure is proposed to improve the ion state conversion efficiency while ensuring high heat dissipation efficiency of the device. Summary of the Invention

[0056] As a preferred solution, the inner spiral air guide pipe 14 includes a tube body 1401, a spiral guide plate 1402 is fixedly installed inside the tube body 1401, and the top and bottom of the outer periphery of the tube body 1401 are both provided with rotating seals 1404, and the rotating seals 1404 are respectively used in conjunction with the upper sealing cavity 8 and the sealed air outlet cavity 12 to ensure the sealing effect during the rotation process.

[0057] To further illustrate, a number of sealing rings are also provided on the outer periphery of the tube body 1401 , and these sealing rings are respectively arranged between the bottom of the upper cooling liquid inlet cavity 9 and the top of the vertical cavity 10 , and between the upper cold plate 1101 and the lower cold plate 1102 described below.

[0058] As a preferred solution, in order to improve the heat dissipation efficiency, a first water channel 3, a second water channel 4 and a third water channel 6 are provided inside the ionization chamber 1. The first water channel 3, the second water channel 4 and the third water channel 6 are connected in sequence, and the inner spiral air guide pipe 14 is rotatably installed inside the second water channel 4.

[0059] As a preferred solution, in order to further improve the ionization efficiency and heat dissipation efficiency, a vertical fan blade drive sleeve 1403 is sleeved and fixedly installed on the outer periphery of the tube body 1401. The vertical fan blade drive sleeve 1403 rotates inside the second water channel 4, and the vertical fan blade drive sleeve 1403 contacts the top of the lower cooling liquid outlet cavity 11, and the guide grooves 1001 are evenly distributed on the outer periphery of the vertical fan blade drive sleeve 1403.

[0060] In order to increase the coverage area of ​​cooling water and improve the heat dissipation efficiency of the equipment, two liquid inlet blind holes 901 are provided on both sides of the upper cooling liquid inlet cavity 9, and two liquid guide blind holes 902 connected to the liquid inlet blind holes 901 are provided at the bottom of the upper cooling liquid inlet cavity 9. The four liquid guide blind holes 902 are respectively connected to the four first water channels 3. A first three-way pipe 903 is fixedly installed on both sides of the upper cooling liquid inlet cavity 9, and the two water outlet ends of the first three-way pipe 903 are respectively arranged on the outer periphery of the two liquid inlet blind holes 901.

The liquid outlet end of the lower cooling liquid outlet cavity 11 is connected to the second three-way pipe 1107.

[0061] During use, the cooling water is introduced into the upper cooling liquid inlet cavity 9 through the two first three-way pipes 903, so that the cooling water enters the liquid guide blind hole 902 through the liquid inlet blind hole 901, and then enters the first water channel 3. The cooling water then enters the second water channel 4 through the guide groove 1001, and drives the vertical fan blade drive sleeve 1403 to drive the tube body 1401 to rotate. After the cooling water exchanges heat with the tube body 1401 in the upper flow of the second water channel 4, it enters the third water channel 6 through the opening, and then the cooling water enters the heat dissipation component 2 through the second three-way pipe 1107.

[0062] As a preferred solution, the heat dissipation component 2 includes a heat-conducting back plate 201 and a cover plate 202. The two heat-conducting back plates 201 are fixedly installed on the front and rear sides of the magnetic core component 13 by bolts respectively. The heat-conducting back plate 201 and the cover plate 202 are fixedly connected by bolts.

[0063] During use, the cooling liquid is diverted through the second three-way pipe 1107 and enters the two heat dissipation components 2 respectively, and flows along the curved water trough 203. During the process, heat is exchanged with the magnetic core component 13 through the thermal back plate 201, and then the cooling water is discharged through the liquid outlet pipe 205, completing the circulation of the cooling water.

[0064] In this embodiment, while increasing the gas residence time, the heat dissipation efficiency of the device can also be improved, and the gas density can be increased through centrifugal action to improve the ionization efficiency.

[0065] Example 2

[0066] On the basis of Example 1, the lower cooling liquid outlet cavity 11 includes an upper cold plate 1101 and a lower cold plate 1102. The top of the upper cold plate 1101 is provided with a liquid guide port 1103 connected to the third water channel 6. The upper cold plate 1101 and the lower cold plate 1102 are provided with rectangular grooves 1104 and mixed flow circular holes 1105 on the opposite sides. The rectangular grooves 1104 are respectively connected to the two liquid guide ports 1103, and the mixed flow circular holes 1105 are connected to the rectangular grooves 1104 through two offset grooves 1106. The bottom of the lower cold plate 1102 is connected to a second three-way pipe 1107 connected to the mixed flow circular hole 1105.

[0067] During use, the cooling water exchanges heat with the tube body 1401 upstream in the second water channel 4, then enters the third water channel 6 through the opening, and then the cooling water enters the rectangular groove 1104 through the liquid guide port 1103. The cooling water enters the mixed flow circular hole 1105 through the two offset grooves 1106 and is mixed, and then discharged from the lower cooling liquid outlet cavity 11 through the second three-way pipe 1107. After being diverted by the second three-way pipe 1107, it enters the two heat dissipation components 2 respectively.

[0068] The advantage of the second embodiment over the first embodiment is that the coolant can be mixed in the mixed flow circular hole 1105 to ensure the uniformity of the temperature of the coolant introduced into the two heat dissipation components 2, thereby providing support for the uniform heat dissipation of the magnetic core component 13.
