Title
(EN) WATER-SPRAYING COOLING DEVICE
(FR) DISPOSITIF DE REFROIDISSEMENT PAR PULVÉRISATION D'EAU
(JA) 水散布冷却装置
Abstract
(EN)
A water-spraying cooling device equipped with a spraying device (20) for spraying water from an upstream side in a predetermined blowing direction toward a heat exchanger (13) that carries out an exchange of heat between air flowing in the blowing direction and a heat medium circulating in the interior of the heat exchanger, wherein the spraying device (20) includes supply holes (206) for supplying the water to be sprayed to the heat exchanger (13), and guide parts (207, 208) that are formed so as to extend downward in the gravity direction from the supply holes (206) and that guide the water supplied from the supply holes (206).
(FR)
L'invention concerne un dispositif de refroidissement par pulvérisation d'eau doté d'un dispositif de pulvérisation (20) servant à pulvériser de l'eau à partir d'un côté amont, dans une direction de soufflage prédéfinie, vers un échangeur de chaleur (13) destiné à effectuer un échange de chaleur entre l'air coulant dans la direction de soufflage et un agent caloporteur circulant à l'intérieur de l'échangeur de chaleur. Le dispositif de pulvérisation (20) comprend des trous d'alimentation (206) permettant d'alimenter l'eau à pulvériser vers l'échangeur de chaleur (13), et des parties de guidage (207, 208) formées de façon à s'étendre vers le bas dans la direction de la gravité à partir des trous d'alimentation (206), et destinés à guider l'eau alimentée à partir des trous d'alimentation (206).
(JA)
予め定められた送風方向へ流れる空気と内部を流通する熱媒体との間で熱交換を行う熱交換器(13)に対し、送風方向の上流側から水を散布する散布装置(20)を備えた水散布冷却装置において、散布装置(20)は、熱交換器(13)に散布される水を供給する供給孔(206)と、供給孔(206)から重力方向下側に延びるように形成され、供給孔(206)から供給される水を誘導するガイド部(207、208)とを含んでいる。
