The air-cooled heat dissipation system 10 enables the liquid storage device 20 to provide low-temperature cooling liquid for the radiotherapy equipment 100 through the power device 30. The air-cooled heat dissipation system 10 achieves the effect of cooling the radiotherapy equipment 100 through the liquid storage device 20, the power device 30 and the air-cooled heat dissipation device 40.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-described examples merely represent several embodiments of the present application and are not to be construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
