Loop Heat Pipe and Electronic Device

An electronic device, comprising:

• a heat generating component;
• a heat receiver thermally connected to the heat generating component;
• a heatsink configured to dissipate heat from the heat generating component received by the heat receiver;
• and
• a loop heat pipe thermally connecting the heat receiver and the heatsink, and has a fluid circulating channel containing fluid, wherein
• the loop heat pipe includes
• an evaporating portion configured to vaporize the fluid by heat from the heat generating component;
• a condensing portion configured to liquefy the fluid vaporized by the evaporating portion;
• a first fluid channel connecting the evaporating portion and the condensing portion, the fluid vaporized by the evaporating portion flowing through the first fluid channel;
• a second fluid channel connecting the evaporating portion and the condensing portion, the fluid liquefied by the condensing portion flowing through the second fluid channel;
• a liquid accumulating portion formed on an inner wall of the second fluid channel, and provided between the evaporating portion and the condensing portion, the liquid accumulating portion configured to accumulate the liquid liquefied by the condensing portion;
• and
• a wick provided between the evaporating portion and a position where the liquid accumulating portion is formed.
