    • A fluid dynamic crossflow cooling tower has a tower body. In the upper portion of the tower body, there is a horizontally disposed injection tubular element which has a plural number of spaced nozzles disposed on the lateral side. Heated fluid is pumped into the injection tubular element and is ejected out through the nozzles and forms a continuous screen of high velocity liquid flow into a horizontal diffuser. Outside cooling air is drawn into the tower through the air inlet located the lower portion of the tower body. The cooling air then mixes with heated liquid in the diffuser to perform heat exchange process. The liquid and air mixture then pass through a mist eliminator which separates liquid from the air. The air is then discharged out of the tower body, liquid is cooled and falls into a water dispersing trough and then passes through a heat radiator for the second pass heat exchanging process, and finally drops into a water tray at the bottom of the tower body. This invention can be adapted for a small size one-way or a large size two-way type cooling tower.
    • 流体动力横流冷却塔具有塔体。 在塔体的上部有水平设置的注射管状元件,其具有设置在侧面上的多个间隔开的喷嘴。 加热流体被泵送到注射管状元件中并通过喷嘴排出并且形成高速液体流入水平扩散器的连续筛网。 外部冷却空气通过位于塔体下部的空气入口吸入塔内。 然后将冷却空气与扩散器中的加热液体混合以进行热交换过程。 液体和空气混合物然后通过一个将空气与空气分离的除雾器。 然后将空气排出塔体,液体冷却并落入水分散槽中,然后通过散热器进行第二次热交换过程,最后落入塔体底部的水盘中 。 本发明可适用于小型单向或大型双向冷却塔。

    • A multi-duct sound eliminator for an air pipe which can be installed din the air inlet or outlet of an air or gas pipe in order to eliminate noise. The outer casing of the sound eliminator can be made in cylindrical shape, a rectangular shape, or a flat shape. The round ducts are arranged in high density matrix to facilitate air flow. For high speed and high temperature air, the sound eliminator uses ducts with air holes covered with metal net, or glass fiber cloth in order to increase the sound absorbing of low frequency noise. Between each duct, sound-absorbing cotton is placed. The ducts are covered by multi-layers of netting material which stack together to prevent the sound-absorbing cotton from being washed out by high speed air flow. For lower speed and lower temperature air, the air channel uses molded sound-absorbing foam to form one unit in which is installed the multi-ducts in order to expand the effectiveness of sound eliminating on low frequency noise.
    • 用于空气管道的多管道除声器,可以安装在空气或气体管道的进气口或出口处,以消除噪音。 除声器的外壳可以制成圆柱形,矩形或扁平形状。 圆形管道以高密度矩阵排列以便于气流。 对于高速和高温空气,除声器使用带有金属网或玻璃纤维布的气孔的管道,以增加低频噪声的吸声。 在每个导管之间放置吸声棉。 管道被多层网状材料覆盖,堆叠在一起,以防止吸声棉被高速气流冲洗掉。 对于低速和低温空气,空气通道使用模制吸声泡沫形成一个单元,其中安装了多通道,以便在低频噪声上扩大声音消除的有效性。
