Abstract
Heat exchange units are disclosed for exchanging heat between at least one fluid, for example water, and a gas, for example air, comprising at least one battery of heat exchange tubes which are parallel to each other and extend generally vertically and in which circulates one of the fluids. The gas, such as air, passes between the tubes of the battery generally transversely of the heat exchange tubes, and means are provided for selectively spraying a liquid on the heat exchanger tubes. The heat exchange units may be employed in atmospheric natural draft, or forced draft coolers, or cooling towers, or combinations of such draft-producing means may be employed in a single cooling tower.
Claims12
Heat exchange unit between at least one fluid, for example water, and a gas, for example atmosphere air, comprising:
- a battery of generally parallel heat exchange tubes;
- means for directing a gas between the tubes of said battery transversely of said heat exchange tubes;
- means for spraying a liquid onto the external surface of said tubes;
- characterized in that said tubes are vertical or steeply inclined to the horizontal and are connected at their upper ends to a first horizontal header or fluid distributing device;
- said spray means comprising a series of spray tubes disposed in alternate parallel relation to said heat exchange tubes;
- connecting means at the upper end of each spray tube;
- a second horizontal distributing device for the liquid to be sprayed, connected to said connecting means;
- said first header or distributing device and said second distributing device being disposed one above the other, and the tubes connected to the device placed above, extending through the device placed there below.
