Electron accelerator irradiation box capable of dissipating heat by means of air cooling

Abstract

The invention discloses an electron accelerator irradiation box capable of dissipating heat by means of air cooling, and relates to the technical field of irradiation, the electron accelerator irradiation box comprises a rectangular duct, an irradiation box and an air guide nozzle type air inlet pipe, one end of the rectangular duct is an air inlet, the other end of the rectangular duct is an airoutlet, and an automatic conveying line is arranged in the rectangular duct; to-be-irradiated goods are arranged on the automatic conveying line, an irradiation box is arranged on the inner wall of the upper side of the rectangular duct, an irradiation box titanium film window is formed in the lower end of the irradiation box and located on the upper side of the to-be-irradiated goods, and an airguide nozzle type air inlet pipe is further arranged on the inner wall of the upper side of the rectangular duct and located on one side of the irradiation box; one end of the air guide nozzle type air inlet pipe is a fresh air inlet, the fresh air inlet is right opposite to the irradiation box, and the fresh air inlet is obliquely formed in the direction close to the irradiation box from top to bottom. The heat dissipation effect is good, a titanium film can be prevented from being burnt through, and equipment is protected.

Description

technical field [0001] The invention relates to the technical field of irradiation, in particular to an electron accelerator irradiation box relying on air cooling for heat dissipation. Background technique [0002] The interior of the electron accelerator irradiation box is a high-vacuum environment, and the outer beam exit is vacuum-sealed with a thin titanium film. When the accelerator is working, the high-energy beam is transmitted through the titanium film. At this time, the titanium film has high energy and temperature. It can reach hundreds of degrees, but the thickness of the titanium film is about 0.02-0.05mm. In this state, the titanium film is very thin and the thermal conductivity of the titanium film is extremely small, which is almost adiabatic, and the heat on the surface of the titanium film under vacuum is irradiating The inside of the box cannot dissipate heat through convective heat exchange, but only through the atmospheric side of the titanium film. If t...

[0002] The interior of the electron accelerator irradiation box is a high-vacuum environment, and the outer beam exit is vacuum-sealed with a thin titanium film. When the accelerator is working, the high-energy beam is transmitted through the titanium film. At this time, the titanium film has high energy and temperature. It can reach hundreds of degrees, but the thickness of the titanium film is about 0.02-0.05mm. In this state, the titanium film is very thin and the thermal conductivity of the titanium film is extremely small, which is almost adiabatic, and the heat on the surface of the titanium film under vacuum is irradiating The inside of the box cannot dissipate heat through convection heat exchange, but only through the atmospheric side of the titanium film. If the heat dissipation is not good, it is easy to cause the titanium film to burn through, causing the equipment to stop or even damage the equipment.
