  • Patent number: 6105663
    Abstract: The present invention relates to a heat dissipation unit for cross flow type cooling tower with which it is possible to prevent the emission of white vapor without lowering the cooling power of the cooling tower, and also without requiring troublesome routine operation. In order to accomplish the above object, the heat dissipation unit of the present invention comprises filling plates arranged vertically and parallel with each other so as to form spaces therebetween, each of the filling plates having uneven surfaces down which water to be cooled flows when water to be cooled is supplied onto the filling plates, and cowl members disposed between neighboring filling plates, each of the cowl members including a pair of side plate portions having upper ends and a roof portion connecting the upper ends of the side plate portions.
    Type: Grant

  • Patent number: 5800743
    Abstract: The present invention relates to a cross flow type cooling tower with which it is possible to prevent the emission of white vapor in cold weather with certainty. In order to accomplish the above object, the cooling tower of the present invention comprises: a heat dissipation unit having filling plates arranged vertically and parallel with each other so as to form dry air passages and moist air passages therebetween, each of the dry air passages and the moist air passages having inner surfaces; water supply means for supplying water to be cooled to the inner surfaces of the moist air passages for cooling the water by contact with air passing through the moist air passage; and water invasion stoppers provided at side ends of the filling plates for preventing the water flowing down the inner surfaces of the moist air passages from invading the dry air passages.
