Loop heat pipe with barrier body in condensation section

A loop type heat dissipation structure, comprising:

• a heat pipe, comprising:
• a pipeline, having a first evaporation section, a first condensation section, an outlet, and an inlet, wherein the outlet is located at an edge of the first evaporation section, and the inlet is located at an edge of the first condensation section;
• a capillary structure, distributed on an inner wall surface of the pipeline and extending from the first condensation section to the first evaporation section;
• and
• a first barrier body, disposed in the first condensation section, and connected to the capillary structure, wherein the capillary structure located in the first condensation section further extends from the first barrier body to the inlet;
• and
• a communicating pipe, wherein an end of the communicating pipe is communicated with the outlet, and another end of the communicating pipe is communicated with the inlet;
• and
• a working fluid, flowing in the heat pipe and the communicating pipe, wherein the working fluid evaporates from a liquid state to a gaseous state in the first evaporation section, thereby forming a first gaseous working fluid that flows in a first flow direction and a second gaseous working fluid that flows in a second flow direction opposite to the first flow direction,
• and the working fluid condenses from the gaseous state to the liquid state in the first condensation section and flows to the first evaporation section along the pipeline through the capillary structure.
