Description

Technical Field

[0001] The utility model relates to the technical field of electron accelerators, and particularly relates to a heat dissipation mechanism for a high-frequency high-voltage electron accelerator. Background Art

[0002] Electron accelerators mainly include large-scale electron accelerators and small-scale electron accelerators. Large-scale electron accelerators are mainly used for scientific research, such as the electron linear accelerators of colliders and free electron lasers; small-scale electron linear accelerators are mainly used in fields such as food irradiation, medical treatment, security inspection, and flaw detection.

[0003] During the long-term use of an electron accelerator, a large amount of heat will be generated inside it. In order to solve the heat dissipation problem, the existing devices usually open heat dissipation holes and set up cooling fans, and the heat inside is taken away by the operation of the cooling fans. However, this method has poor heat dissipation effect, and the cooling fans in the existing devices usually directly suck in external air, which will cause dust in the air to accumulate on the inner surface of the electron accelerator, thus affecting its heat dissipation effect and having low practicability. Content of the Utility Model

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a heat dissipation mechanism for a high-frequency high-voltage electron accelerator, which can solve the problems that the existing devices usually open heat dissipation holes and set up cooling fans to take away the heat inside by the operation of the cooling fans, but this method has poor heat dissipation effect, and the existing fans usually directly suck in external air, which will cause dust in the air to accumulate on the inner surface of the electron accelerator, thus affecting its heat dissipation effect and having low practicability.

On the opposite ends of the four groups of fixing blocks, a groove line coil, a radio frequency electrode, a main body, and an accelerating tube assembly are fixedly installed in sequence from left to right;
