To uniformly spray water to a heat exchanger in a water spraying cooling device for spraying water to the heat exchanger to improve cooling capacity of the heat exchanger.SOLUTION: A water spraying cooling device includes a spraying device 20 for spraying water to a heat exchanger 13 exchanging heat between air flowing in a predetermined air blowing direction and a heating medium flowing therein, from the upstream side in the air blowing direction. The spraying device 20 includes: supply holes 206 for supplying water to be sprayed to the heat exchanger 13; and guide parts 207, 208 formed to extend from the supply holes 206 to the lower side in the gravity direction to guide water supplied from the supply holes 206. The plurality of supply holes 206 are provided, and the guide parts 207, 208 are provided to correspond to the plurality of supply holes 206, respectively. Groove parts 207b, 208b for guiding the water supplied from the supply holes 206 are formed in the guide parts 207, 208.SELECTED DRAWING: Figure 7
【課題】熱交換器に水を散布し、熱交換器の冷却能力を向上させる水散布冷却装置において、熱交換器に均一に水を散布する。【解決手段】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とを含んでおり、供給孔206は複数設けられており、ガイド部207、208は複数の供給孔206のそれぞれに対応して設けられている。ガイド部207、208には、供給孔206から供給された水を誘導する溝部207b、208bが形成されている。【選択図】図7
