Abstract
(EN)
This cooling system 2 is provided with a duct 50 and a cooling enhancing unit 60. The duct 50 is formed such that, when an enclosed space is formed by at least any of a plurality of surfaces forming an exterior shape of a shielding member 80 and an intake surface or an exhaust surface among a plurality of surfaces forming an exterior shape of a plurality of heat-generating housings 70 in such a way that an airflow that is taken in and an airflow that is exhausted by the plurality of heat-generating housings 70 installed side by side in at least two rows can be separated or substantially separated, it is possible to separate or substantially separate a first airflow that is taken in or exhausted by a specific heat-generating housing 71 among the plurality of heat-generating housings 70, and a second airflow that is taken in or exhausted by the heat-generating housings 70 other than the specific heat-generating housing 71. The cooling enhancing unit 60 acts on the first airflow to enhance cooling power with respect to the specific heat-generating housing 71. In this way, in a system in which an air-conditioning environment, such as aisle capping, is constructed, it becomes possible to efficiently avoid the generation of a hot spot due to the presence of a heat-generating housing generating a large amount of heat.
(FR)
Ce système de refroidissement 2 est pourvu d'un conduit 50 et d'une unité d'amélioration de refroidissement 60. Le conduit 50 est formé de telle sorte que, lorsqu'un espace fermé est formé par au moins l'une quelconque d'une pluralité de surfaces formant une forme extérieure d'un élément de protection80 et d'une surface d'admission ou d'une surface d'échappement parmi une pluralité de surfaces formant une forme extérieure d'une pluralité de boîtiers de génération de chaleur 70 de telle sorte qu'un flux d'air qui est aspiré et un flux d'air qui est évacué par la pluralité de boîtiers de génération de chaleur 70 installés côte à côte dans au moins deux rangées peuvent être séparés ou sensiblement séparés, il est possible de séparer ou de séparer sensiblement un premier flux d'air qui est admis ou évacué par un boîtier de génération de chaleur spécifique 71 parmi la pluralité de boîtiers de génération de chaleur 70, et un second flux d'air qui est admis ou évacué par les boîtiers de génération de chaleur 70 autres que le boîtier de génération de chaleur spécifique 71. L'unité d'amélioration de refroidissement 60 agit sur le premier flux d'air pour améliorer la puissance de refroidissement par rapport au boîtier de génération de chaleur spécifique 71. De cette manière, dans un système dans lequel un environnement de climatisation, tel qu'un recouvrement d'allée, est construit, il devient possible d'éviter efficacement la génération d'un point chaud en raison de la présence d'un boîtier de génération de chaleur générant une grande quantité de chaleur.

冷却システム2は、少なくとも2列に並べて設置された複数の発熱筐体70により吸気される気流と排気される気流とが、分離あるいは略分離されるように、遮蔽部材80の外面形状をなす複数面のうちの少なくともいずれかと、複数の発熱筐体70の外面形状をなす複数面のうち吸気面あるいは排気面とによって、囲まれた空間が形成されている場合に、複数の発熱筐体70のうちの特定の発熱筐体71により吸気あるいは排気される第一の気流と、特定の発熱筐体71を除く他の前記発熱筐体70により吸気あるいは排気される第二の気流とを、分離あるいは略分離可能に形成されたダクト50と、第一の気流に作用することによって、特定の発熱筐体71に対する冷却力を強化する冷却強化部60と、を備えることにより、アイルキャッピングのような空調環境が構築されたシステムにおいて、発熱量が高い発熱筐体の存在によるホットスポットの発生を、効率的に回避する。
