Heat dissipation structure and inspection apparatus

A heat dissipation structure, comprising:

• a supporting frame configured to rotate around a central axis of the supporting frame;
• a heat source arranged on the supporting frame and configured to rotate with the supporting frame;
• and
• a radiator configured to receive from the heat source a fluid heated by the heat source and input the cooled fluid to the heat source;
• wherein the radiator is arranged on a periphery of the supporting frame relative to the central axis, and when the supporting frame rotates around the central axis of the supporting frame, the radiator is configured to allow air to enter into the radiator via an air inlet opening of the radiator and to be expelled from the radiator via an air outlet opening of the radiator;
• wherein the radiator comprises a first plate and a second plate, the first plate and the second plate are opposite each other to allow the air to pass between the first plate and the second plate so as to remove heat from the first plate and the second plate, and the first plate is farther away from the central axis than the second plate;
• and
• wherein the radiator comprises a heat pipe arranged in the first plate and the second plate, and the fluid flows through the heat pipe.
