Referring to fig. 1 to 8, an embodiment of the present application provides an X-ray blood irradiator 100, which includes a housing 101, a frame 110, and a functional module.

Further, a chassis 110 is provided within the housing 101. The case 101 has a heat radiation hole 102, and heat inside the case 101 can be discharged from the heat radiation hole 102.

Functional modules are provided on the rack 110. The functional module comprises an X-ray generator 120, a high voltage generator 130, an industrial personal computer 140 and a shielding cavity 123.
