Title: COOLING SYSTEM, COOLER, AND COOLING METHOD
Abstract:
Provided is a cooling system able to cool efficiently, without requiring a drive source for a refrigerant, even for a plurality of densely-mounted electronic components having a high level of generated heat. This cooling system (1) comprises: a heat-receiving section (11) having a substantially constant cross-sectional area along a longitudinal direction in which the length of a cooling region (10) where heat sources are cooled, such length following the disposition of the heat sources, is the greatest; a supply tube (12) for supplying refrigerant in a liquid state to inside the heat-receiving section; a recovery tube (13) for recovering the refrigerant, which is vaporized when receiving the heat, from inside the heat-receiving section; and a heat radiation section (14) for cooling the recovered refrigerant and supplying same in a liquid state to the supply tube. The heat-receiving section has a refrigerant pathway (15) for causing the refrigerant supplied from the supply tube to flow out into the heat-receiving section along the longitudinal direction.
