Flat loop heat pipe

A flat loop heat pipe, comprising

• an evaporator that vaporizes a working fluid;
• a condenser that liquefies the working fluid vaporized by the evaporator;
• a vapor pipe that connects the evaporator to the condenser;
• and
• a liquid pipe that connects the condenser to the evaporator and includes a first wick, wherein
• the vapor pipe includes a first wall and a second wall, the second wall being spaced apart from and facing the first wall,
• the liquid pipe includes a third wall and a fourth wall, the fourth wall being spaced apart from and facing the third wall,
• the condenser includes
• a flow passage that connects the vapor pipe and the liquid pipe,
• a second wick connected to the first wick,
• a fifth wall connecting the first wall of the vapor pipe and the third wall of the liquid pipe,
• a sixth wall extending from the second wall of the vapor pipe,
• a seventh wall extending from the fourth wall of the liquid pipe, and
• an eighth wall spaced apart from and facing the fifth wall, the eighth wall connecting the sixth wall and the seventh wall, wherein
• the second wick is formed integrally with the sixth wall, the seventh wall, and the eighth wall,
• the second wick includes an end portion spaced apart from and facing the fifth wall,
• the flow passage of the condenser is defined by the end portion of the second wick and the fifth wall of the condenser and is formed along the fifth wall of the condenser, and
• the fifth wall of the condenser is free from the first wick and the second wick.
