Abstract:
1. An electronic device comprising: a housing; a plurality of heat generating parts contained in the housing; and a loop heat pipe contained in the housing and formed by sealing an operating fluid in an annular internal fluid path, the loop heat pipe comprising: a heat receiving portion thermally connected to the heat generating parts; a heat radiating portion configured to release the heat transmitted from the heat receiving portion to the outside; a vapor flow path which connects the heat receiving portion and the heat radiating portion to each other, and through which the operating fluid evaporated by the heat receiving portion flows to the heat radiating portion; and a liquid return flow path which is provided independently of the vapor flow path and connects the heat receiving portion and the heat radiating portion to each other, and through which the fluid flows to the heat receiving portion, and the heat receiving portion further comprises a first region connected to the liquid return flow path and provided with a wick, and a second region formed to be hollow and connected to the vapor flow path, and is thermally connected to the heat generating parts at a position across the first region and the second region, the heat generating parts are arranged in line on a border line between the first region and the second region.
