Water to Air Copper Tube Aluminium Finned Heat Exchanger for Boiler

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. 

Materials: Carbon steel-aluminum rolled sheet, stainless steel-aluminum rolled sheet and 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. 

Materials: Carbon steel coiled sheet and 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.

This product has been extensively applied in air conditioning, cooling, dehumidifying and heating projects. As an ideal supporting product for the updated air draught unit and air processor, it can also be connected to air tube for independent utilization for a cooling or heating purpose.

High-frequency welding air heat exchanger has been extensively applied in such industries as petrifaction, power plant, power plant modification, air conditioning & refrigeration, boiler, finned-type coal saver and air preheater.

The finned tube in high-frequency welding air heat exchanger is made by coiling band steel around plate fin and firmly soldering plate fin onto finned tube through using high-frequency welding process, which can ensure intensity of combination between finned tube and plate fin. Featuring high intensity, resistance to thermal vibration and mechanical vibration, good thermal expansion performance, large cooling surface and long service life, it has a wide range of applicable temperature, endurance of high pressure and other features.

Plate air heat exchanger is a type of environmental-friendly product which is used to recover heat, reduce energy consumption and save fuels. It is applicable to devices used to convert natural gas, oil gas, naphta and other raw materials into chlorine as air combustion heater. Plate air heat exchanger has been extensively applied in chlorine-making conversion furnace or depolymerizing furnace in large-scale chemical engineering enterprises as well as waste heat recovery projects in steel industry and glass industry.

The product features compact structure and flexible design which can effectively avoid thermal expansion and corrosion of exposed points. With high heat exchange efficiency and small volume, it can meet the demand of large-sized equipment. Its volume is one third of the volume of tube air preheater.
