    • A liquid droplet jetting apparatus includes a jetting head unit which has a nozzle which jets droplets of a liquid, and a heat generating section, a suction port which is formed in the jetting head unit, and which opens near the nozzle, and a suction device which sucks air around the nozzle from the suction port, and cools down the heat generating section of the jetting head unit by the air which is sucked. Since the heat generating portion is cooled down by the air sucked from the suction port by the suction device, it is possible to reduce a possibility of the heat of the heat generating section being transferred to the jetting head unit, and destabilizing an operation of the jetting head unit. Moreover, since the suction port opens near the nozzle, it is possible to suck fine liquid droplets together with air around the nozzle.
    • 液滴喷射装置包括喷射头单元,该喷射头单元具有喷射液滴的喷嘴和发热部,形成在喷射头单元中并在喷嘴附近打开的吸入口,以及抽吸装置 其从吸入口吸附喷嘴周围的空气,并且通过被吸入的空气冷却喷射头单元的发热部。 由于通过由吸引装置从吸入口吸入的空气将发热部冷却下来,因此能够降低发热部的热量向喷射头单元的转移的可能性, 喷头单元。 此外,由于吸入口在喷嘴附近打开,所以可以与喷嘴周围的空气一起吸入细液滴。
