Loop heat pipe, method of manufacturing the same, and electronic device

An electronic device comprising:

• a heat generating component;
• and
• a loop heat pipe configured to cool the heat generating component, wherein
• the loop heat pipe comprises;
• an evaporator configured to vaporize a working fluid with a heat of the heat generating component;
• a condenser configured to liquefy the working fluid;
• a liquid line connecting the evaporator and the condenser;
• a porous body provided in a columnar shape in the liquid line;
• and
• a vapor line connecting the evaporator and the condenser, and forming a loop together with the liquid line.

A method of manufacturing a loop heat pipe, comprising:

• forming an evaporator, a condenser, a liquid line, and a vapor line by stacking a plurality of metallic layers;
• forming a porous body of a columnar shape in the liquid line by forming a plurality of pores in a portion of the metallic layer that corresponds to the liquid line;
• and
• pouring a working fluid into the liquid line.
