Study Of Improvement Measure Of Air Cooler

A dry tower is a tower in which no direct contact between the air and water is allowed, the packing of the conventional et?tower being replaced by heat exchangers. Because of its much less water loss compared to wet tower, dry tower can operate on many sites where wet towers are impossible due to the unavailability of the necessary external water supply. As the number of suitable sites for wet towers on rivers, lakes and estuaries decrease with the expansion of industrialization, so dry towers become increasingly attractive. It is common practice for heat exchangers to be designed for ease of manufacturing. Although used for all kinds of applications, the geometry remains fixed and the desired duty is achieved by adjusting the heat transfer area. However the above procedure is not satisfactory for instance on thermodynamic grounds. A project to redesign and optimize water梐ir heat exchanger elements was initiated, that includes analytical optimization of the heat exchanger geometry, computation of the structure of dry tower In this thesis, A new type structure of cooler was elected. And its character of heat transfer as well as the measure of protecting pipe from freezing was studied.
