Description

Heat dissipation mechanism of electron accelerator Technical Field The utility model relates to the technical field of electron irradiation accelerators, in particular to a heat dissipation mechanism of an electron accelerator. Background The irradiation accelerator can produce physical, chemical and biological effects on some substances by high-energy electron beam irradiation generated by the electron accelerator, and can effectively kill germs, viruses and pests, and a large amount of heat can be generated in the electron accelerator in the long-time use process. Through retrieval, in the application of patent application number 202220784049.0, a heat dissipation mechanism of a high-power electron irradiation accelerator is disclosed, and relates to the technical field of electron irradiation accelerators, and the heat dissipation mechanism comprises an outer shell, wherein the outer shell is in a cylindrical shape, the bottom of the outer shell is in a penetrating arrangement, a safety cylinder is arranged in the outer shell, the lower surface of the safety cylinder is fixedly connected with a first connecting ring, the upper surface of the safety cylinder is fixedly connected with a second connecting ring, a thread is arranged on the inner surface of the outer shell close to the top, and a mounting ring is in threaded connection with the inner surface of the outer shell close to the top; Although the heat radiation mechanism of the high-power electron irradiation accelerator is started by the heat radiation fan, then air enters between the outer shell and the safety cylinder along the position of the filter screen frame, then the air is discharged along the heat radiation fan, and the heat radiation is carried out on the device by the air, the air inlet and the air outlet of the heat radiation mechanism of the high-power electron irradiation accelerator adopt the same channel design mode, and the single channel structure ensures that the circulation path of the air in the equipment is limited. When air carries impurities such as dust to flow through the filter screen frame, the dust can be gradually accumulated on the surface of the filter screen to form a blockage. Once the screen frame is plugged, the air flow resistance increases significantly, making it difficult for air to pass smoothly through the apparatus. Because the circulation of air is not smooth, the heat generated in the running process of the equipment can not be effectively taken away, and good heat exchange circulation is difficult to form, so that the heat dissipation efficiency of the equipment is greatly reduced. The long-term poor heat dissipation state can reduce the running performance and stability of the equipment, and can shorten the service life of the equipment, thereby seriously affecting the normal use and working efficiency of the equipment. Therefore, we propose a heat dissipation mechanism for an electron accelerator.
