Description

Technical Field

[0001] This utility model relates to the field of electron irradiation accelerator technology, specifically to a heat dissipation mechanism for an electron accelerator. Background Technology

[0002] Irradiation accelerators use high-energy electron beams generated by electron accelerators to produce physical, chemical and biological effects on some substances, and can effectively kill bacteria, viruses and pests. During long-term use, electron accelerators generate a lot of heat inside.

[0003] A search revealed that patent application number 202220784049.0 discloses a heat dissipation mechanism for a high-power electron irradiation accelerator, relating to the field of electron irradiation accelerator technology. The mechanism includes an outer shell, which is cylindrical with a through-hole at the bottom. A safety cylinder is located inside the outer shell. A first connecting ring is fixedly connected to the lower surface of the safety cylinder, and a second connecting ring is fixedly connected to the upper surface of the safety cylinder. A thread is formed on the inner surface of the outer shell near the top, and a mounting ring is threaded onto the inner surface of the outer shell near the top.

[0004] Although the heat dissipation mechanism of this high-power electron irradiation accelerator is activated by a cooling fan, and air then enters between the outer casing and the safety cylinder along the filter frame before being exhausted by the cooling fan, thus dissipating heat from the device, the air inlet and outlet of this heat dissipation mechanism are designed with the same channel. This single-channel structure restricts the airflow path within the equipment. When air carrying dust and other impurities flows through the filter frame, dust gradually accumulates on the filter surface, causing blockage. Once the filter frame is blocked, the airflow resistance increases significantly, making it difficult for air to pass through the equipment smoothly. Due to poor airflow, the heat generated during equipment operation cannot be effectively removed, hindering the formation of a good heat exchange cycle and resulting in a significant decrease in the equipment's heat dissipation efficiency. Prolonged exposure to this poor heat dissipation not only reduces the equipment's operational performance and stability but may also shorten its lifespan, seriously affecting its normal use and operational efficiency.

[0005] Therefore, we propose a heat dissipation mechanism for an electron accelerator. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a heat dissipation mechanism for an electron accelerator, which solves the problems of existing devices having the same air inlet and outlet, and the filter frame being clogged by dust, resulting in poor air circulation and consequently poor heat dissipation.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat dissipation mechanism for an electron accelerator, comprising a cylindrical outer shell, the bottom of which is open and a connecting flange is fixedly installed at the top. A first mounting post and a second mounting post are fixedly installed at the top and bottom of the outer surface of the outer shell, respectively. A threaded acceleration coil is fixedly fitted on the inner wall of the outer shell, and the two ends of the acceleration coil are fixedly connected to the second mounting post and the first mounting post, respectively.

[0008] A heat dissipation component is provided on the outer surface of the outer casing, and a flow guiding component is provided at the bottom end of the outer surface of the outer casing.

[0009] The heat dissipation assembly includes a first annular plate that is threaded onto the top of the outer surface of the outer shell and is hollow inside. The bottom surface of the first annular plate has evenly distributed air outlet holes. A connecting pipe is fixedly connected to the side wall of the first annular plate. The end of the connecting pipe away from the first annular plate is connected to the output end of an external air blowing device. Heat dissipation fins are provided in the middle of the outer surface of the first annular plate.

[0010] Preferably, the heat dissipation assembly further includes two semi-circular plates sleeved on the outer surface of the outer shell. Each end of the two semi-circular plates is fixedly installed with a connecting plate. Adjacent connecting plates are fixed together by bolts and nuts. The heat dissipation fins are fixedly installed on the outer surface of the semi-circular plates and distributed in a ring array. This allows the semi-circular plates to be removed from the outer surface of the outer shell. Heat inside the outer shell is conducted to the semi-circular plates, and then to the heat dissipation fins through the semi-circular plates, and finally dissipated into the outside air through the heat dissipation fins.

[0011] Preferably, the inner diameter of the semi-circular plate is the same as the outer diameter of the outer shell, the inner wall of the semi-circular plate is fitted with the outer wall of the outer shell, and both the semi-circular plate and the heat dissipation fins are made of copper, wherein copper has extremely strong thermal conductivity to facilitate rapid heat dissipation.

[0012] Preferably, the external air blowing device is a blower, wherein the blower blows air into the connecting pipe, and then the gas enters the interior of the first annular plate through the connecting pipe and is discharged through the air outlet, which can increase the air circulation rate around the heat dissipation fins, so as to facilitate heat exchange between the heat dissipation fins and the air.

[0013] Preferably, the airflow guiding component includes a second annular plate and an airflow guiding hopper. The second annular plate is threaded onto the outer surface of the bottom end of the housing, and the airflow guiding hopper is fixedly installed on the bottom surface of the second annular plate. The airflow guiding hopper facilitates the outward diffusion of the air blown out through the air outlet, preventing the air from entering the interior of the heat dissipation component and affecting the trajectory of the electrons.

[0014] This invention provides a heat dissipation mechanism for an electron accelerator. It has the following beneficial effects:

[0015] 1. The heat dissipation mechanism of this electron accelerator absorbs the heat generated inside the outer shell through a semi-circular plate and heat dissipation fins. Air is blown into the connecting pipe through an external air blowing device, and then the gas enters the interior of the first annular plate through the connecting pipe and is discharged through the air outlet. This increases the air circulation rate around the heat dissipation fins, allowing the heat dissipation fins to exchange heat with the outside air, thereby carrying away the heat inside the heat dissipation fins and semi-circular plate. This helps maintain a stable heat dissipation effect and makes it easy to disassemble the first annular plate and semi-circular plate for maintenance or replacement. It is simple and convenient to use and solves the problem that the air inlet and outlet of the existing device are the same, and the filter frame is blocked by dust, resulting in poor air circulation and thus poor heat dissipation effect.

[0016] 2. The heat dissipation mechanism of the electron accelerator can diffuse the air blown out through the air outlet to the outside through the guide bucket, which helps to prevent the air from entering the heat dissipation component and affecting the trajectory of the electrons.

Detailed Implementation

[0022] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] like Figure 1-4As shown: The system includes a cylindrical outer shell 1, with an open bottom and a connecting flange 11 fixedly mounted at the top. A first mounting post 12 and a second mounting post 13 are fixedly mounted at the top and bottom of the outer surface of the outer shell 1, respectively. A threaded acceleration coil 14 is fixedly fitted onto the inner wall of the outer shell 1, with both ends of the acceleration coil 14 fixedly connected to the second mounting post 13 and the first mounting post 12, respectively. A heat dissipation assembly 2 is provided on the outer surface of the outer shell 1, and a flow guiding assembly 3 is provided at the bottom of the outer surface of the outer shell 1. The heat dissipation assembly 2 includes a first annular plate 21 threaded onto the top of the outer surface of the outer shell 1 and hollow inside. The bottom surface of the first annular plate 21 has evenly distributed air outlet holes 211. A connecting pipe 22 is fixedly connected to the side wall of the first annular plate 21, with the end of the connecting pipe 22 away from the first annular plate 21 connected to the output end of an external air blowing device. Heat dissipation fins 25 are provided in the middle of the outer surface of the first annular plate 21. The heat dissipation assembly 2 also includes two semi-circular plates 23 fitted onto the outer surface of the outer shell 1. Connecting plates 24 are fixedly installed at both ends of the semi-circular plate 23. Adjacent connecting plates 24 are fixed together by bolts and nuts. Heat dissipation fins 25 are fixedly installed on the outer surface of the semi-circular plate 23 and distributed in a ring array. The inner diameter of the semi-circular plate 23 is the same as the outer diameter of the outer shell 1. The inner wall of the semi-circular plate 23 is in contact with the outer wall of the outer shell 1. The semi-circular plate 23 and the heat dissipation fins 25 are both made of copper. The external air blowing device is a blower. The heat generated inside the outer shell 1 is absorbed by the semi-circular plate 23 and the heat dissipation fins 25. Air is blown into the connecting pipe 22 by the external air blowing device. Then the gas enters the interior of the first ring plate 21 through the connecting pipe 22 and is discharged through the air outlet 211. This can increase the air circulation rate around the heat dissipation fins 25, so that the heat dissipation fins 25 can exchange heat with the outside air. Then the heat inside the heat dissipation fins 25 and the semi-circular plate 23 is carried away, which is conducive to maintaining a stable heat dissipation effect. It is also easy to disassemble the first ring plate 21 and the semi-circular plate 23 for maintenance or replacement. It is simple and convenient to use.

[0025] Example 2:

[0026] like Figure 1 and 4 As shown: The flow guiding component 3 includes a second annular plate 31 and a flow guiding bucket 32. The second annular plate 31 is threaded onto the outer surface of the bottom end of the outer shell 1. The flow guiding bucket 32 ​​is fixedly installed on the bottom surface of the second annular plate 31. The flow guiding bucket 32 ​​can diffuse the air blown out through the air outlet 211 to the outside, which helps to prevent the air from entering the interior of the heat dissipation component 2 and affecting the trajectory of the electron movement.

[0027] The working principle and usage process of this utility model: In use, the heat dissipation mechanism of this electron accelerator is connected to the input end of the irradiation accelerator using bolts. When the irradiation accelerator is running, the heat generated inside the outer shell 1 is conducted to the semi-circular plate 23 and the heat dissipation fins 25. The external air blowing device is activated to blow air into the connecting pipe 22. Then, the gas enters the interior of the first annular plate 21 through the connecting pipe 22 and is discharged through the air outlet 211. This can increase the air circulation rate around the heat dissipation fins 25, thereby carrying away the heat inside the heat dissipation fins 25 and the semi-circular plate 23. The air blown out through the air outlet 211 can be diffused to the outside through the guide bucket 32, preventing the air from entering the interior of the heat dissipation component 2 and affecting the trajectory of the electrons.
