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.
Rolling-type Air Heat Exchanger
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
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.
Plate-fin Air Heat Exchanger
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
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.
Tube Air Heat Exchanger
|Tube air heat exchanger is a type of air preheater that has been extensively applied in China. It is composed of many steel tubes which are arrayed in paralleled and staggered way. Two ends of the tube are soldered to the tube plate to form a cubic tube case with certain heating surface.|
Tube air heat exchanger features high heat transfer efficiency, simple structure, easy manufacturing, small theoretical air leakage quantity, good sealing performance, and less tube abrasion. It is extensively applied in waste heat recovery projects in such industries as petroleum, chemical engineering, metallurgy, electric power and environmental protection.
Plate Air Heat Exchanger
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.
Features of Plate Air Heat Exchanger:
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.
