Natural convection cooling tower type air cooling system

Abstract

The invention provides a natural convection cooling tower type air cooling system. The system comprises a natural convection tower body. Multiple sets of heat exchangers and a supporting structure are arranged in the tower body. The heat exchangers comprise multiple communicated tube bundle boxes. Each tube bundle box comprises multiple sets of finned tubular tube bundles. The tube bundles are composed of tubular finned tubes. Rolled spiral fins are combined to the outer side walls of the finned tubes. An input joint of the communicated tube bundle boxes is communicated with a water inflow pipeline of the tower body. A water outlet is communicated with a water outflow tube opening of the tower body. The natural convection cooling tower type air cooling system has the beneficial effects that the convection effect is generated inside and outside the natural convection cooling tower through air, air in the tower exchanges heat through the surfaces of the metal composite rolled spiral fins, natural convection air is adopted for heat exchange to enhance heat exchange efficiency, and meanwhile, energy and water resource waste is reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a natural convection cooling tower type air cooling system. Background technique [0002] In the natural environment of production and life in human society, the energy conversion methods except wind energy and water energy are directly used and converted in the form of mechanical energy. The energy obtained in this way accounts for a very small part of the energy demand of the entire human society, and absolutely Most of the 95% energy obtained is the energy conversion of fossil energy in the form of "heat engine", which requires "heat exchange". From the beginning of industrialization to the present, the theoretical efficiency of "heat exchange" is 50-60%, but the efficiency of "heat exchange" in practical application is very low. The energy conversion efficiency of coal, oil and gas boilers is 2-7%, and the energy conversion of internal combustion engines The efficiency...

Problems solved by technology

From the beginning of industrialization to the present, the theoretical efficiency of "heat exchange" is 50-60%, but the efficiency of "heat exchange" in practical application is very low. The energy conversion efficiency of coal, oil and gas boilers is 2-7%, and the energy conversion of internal combustion engines Efficiency 10-15%, power energy conversion efficiency 25-30%, the result of low energy conversion efficiency is very serious waste of energy and resources
