Heat dissipation structure and neutron beam generating device using the same

A neutron beam generating device, comprising:

• a heat dissipation structure comprising:
• a housing having an upper surface, a lower surface opposite to the upper surface, and a fluid channel disposed between the upper surface and the lower surface, wherein the fluid channel is configured to allow a fluid to pass through, and the fluid channel comprises:
• an inlet buffer tank having a first inner wall surface and a second inner wall surface opposite the first inner wall surface;
• an outlet buffer tank having a first inner wall surface and a second inner wall surface opposite the first inner wall surface, and the second inner wall surface of the outlet buffer tank is closer to the inlet buffer tank than the first inner wall surface of the outlet buffer tank is, wherein the second inner wall surface of the inlet buffer tank is closer to the outlet buffer tank than the first inner wall surface of the inlet buffer tank is;
• and
• a connecting structure disposed on the inlet buffer tank and the outlet buffer tank, wherein the connecting structure has a first bevel surface and a second bevel surface directly connected to the upper surface of the housing and in contact with the fluid;
• an ion beam tubular body having a channel, wherein the ion beam tubular body is disposed above the heat dissipation structure and directed toward the upper surface of the housing of the heat dissipation structure, and a gap is between the ion beam tubular body and the upper surface of the housing of the heat dissipation structure;
• and
• an accelerator connected to the ion beam tubular body and configured to emit an ion beam toward the upper surface of the housing of the heat dissipation structure through the channel.
