Title (EN) COOLING SYSTEM AND COOLING METHOD
(FR) SYSTÈME DE REFROIDISSEMENT ET PROCÉDÉ DE REFROIDISSEMENT
(JA) 冷却システム及び冷却方法
Abstract:
(EN) Provided are: a cooling system having a simple configuration, which is capable of maintaining adequate cooling performance even in cases where the load of an electronic device is not uniform; and a cooling method. A cooling system of the present invention is provided with: a plurality of evaporators, each of which stores a first coolant; a plurality of heat exchangers that are respectively arranged above the plurality of evaporators; a plurality of first pipes that constitute first coolant circulating systems, which independently work for respective evaporators, and each of which circulates the first coolant between corresponding evaporator and heat exchanger; an external heat exchanger which cools the first coolant of the plurality of heat exchangers through a second coolant; and a second pipe that constitutes a second coolant circulating system that circulates the second coolant between the external heat exchanger and the plurality of heat exchangers.
(FR) L'invention concerne un système de refroidissement ayant une configuration simple, capable de maintenir des performances de refroidissement adéquates même dans des cas où la charge d'un dispositif électronique n'est pas uniforme; et un procédé de refroidissement. Un système de refroidissement selon la présente invention comprend : une pluralité d'évaporateurs stockant chacun un premier réfrigérant; une pluralité d'échangeurs de chaleur respectivement disposés au-dessus de la pluralité d'évaporateurs; une pluralité de premiers tuyaux qui constituent des premiers systèmes de circulation de réfrigérant, qui fonctionnent indépendamment pour des évaporateurs respectifs, chacun d'eux faisant circuler le premier réfrigérant entre un évaporateur et un échangeur de chaleur correspondants; un échangeur de chaleur externe qui refroidit le premier liquide de refroidissement de la pluralité d'échangeurs de chaleur par l'intermédiaire d'un second réfrigérant; et un second tuyau qui constitue un second système de circulation de réfrigérant qui fait circuler le second réfrigérant entre l'échangeur de chaleur extérieur et la pluralité d'échangeurs de chaleur.
(JA)  電子機器の負荷が不均一である場合でも冷却性能を維持できる、単純な構成の冷却システム及び冷却方法を提供する。 本発明の冷却システムは、第1の冷媒を貯蔵する複数の蒸発器と、複数の蒸発器の上方にそれぞれ配置される複数の熱交換器と、対応する蒸発器および熱交換器との間で第1の冷媒を循環させ、蒸発器毎に独立した第1の冷媒循環系を構成する複数の第1の配管と、複数の熱交換器において第1の冷媒を第2の冷媒を介して冷却する外部熱交換器と、外部熱交換器と複数の熱交換器との間で第2の冷媒を循環させ、第2の冷媒循環系を構成する第2の配管と、を備える。
