Air to air heat exchanger for exhausted flue gas heating recovery systems
What is an air heat exchanger?
Air heat exchanger is a kind of heat exchanger that is used to cool or heat forcibly flowing air with water, glycol solution, steam or heat conduction oil as the medium. It is extensively applied in hot air heating, drying, cooling, dehumidifying and other works in such industries as light industry, building, chemical engineering, machinery, textile, printing & dyeing, electronics, food, starch, medication, metallurgy and painting. Different models of heat exchanger should be selected according to the actual working conditions.
What types of heat exchangers are available?
Advanced steel-aluminum composite technology is adopted in rolling-type air heat exchanger which is featured by compact combination, small thermal resistance, strong heat transfer performance, small flow loss, good anti-corrosive performance, remote possibility for distortion under long-term cold/hot working conditions, and long service life, etc.
Carbon steel-aluminum rolled sheet
Stainless steel-aluminum rolled sheet
Steel tube-aluminum rolled sheet
Coiling-type air heat exchanger features compact structure, aesthetic appearance, easy installation, convenient management and long service life. It is applicable to centralized air-supply heating, local heating or other purposes.
Carbon steel coiled sheet
Stainless steel coiled sheet
Advanced mechanical expansion tube and arc corrugation sheet with double flanged aluminum-finned sheets are adopted in plate-fin air heat exchanger. Mechanical expansion tube makes copper tube come into close contact with aluminum-finned sheet; arc corrugation can promote turbulent flow of fluid, destruct boundary layer of air, and raise heat transfer coefficient.
Advanced structural form as well as reasonably-designed water travel, tube pass and spacing between sheets provide the following features of the heat exchanger: good heat transfer performance, small air resistance, compact structure and light weight, etc.
