1. Wound air heat exchanger.
Wrap-around air heat exchangers are characterized by compact structure, beautiful appearance, easy installation, convenient management and durability.
Material: carbon steel wound steel sheet and stainless steel wound steel sheet, etc.
2. Rolled-plate air heat exchanger.
The plate-type air heat exchanger adopts advanced steel-aluminum composite technology, which has close combination, small thermal resistance, high heat transfer performance, small flow loss, good corrosion resistance, and is not easy to deform under long-term cold and hot working conditions. Long advantages.
Material: Carbon steel rolled aluminum sheet, stainless steel rolled aluminum sheet and copper tube rolled aluminum sheet.
3. String-plate air heat exchanger
The cascade-type air heat exchanger uses advanced mechanical expansion tubes and circular corrugated double-flanged aluminum fin structure fins. The mechanical expansion tube brings the copper tube into close contact with the aluminum fins, and the arc ripple can promote the turbulent flow of the fluid, destroy the air boundary layer, and improve the heat transfer coefficient. The advanced structure, coupled with the reasonable design of the number of tubes and the distance between the slices, make the heat exchanger have the characteristics of good heat transfer performance, small air resistance, compact structure and light weight. It is widely used in air conditioning, cooling, dehumidification, heating and other projects. It is the ideal supporting product for the latest fan unit and air handler. It can also be connected to the air pipe as a cooling or heating alone.
4. High frequency welding air heat exchanger.
High-frequency welding air heat exchangers are widely used in petrochemical, power plant transformation, boilers, fin economizers and air preheaters.
The finned tube of the high-frequency welding air heat exchanger is to wrap the steel strip on the fin, and the high-frequency welding process is used to weld the fin to the tube to ensure the bonding strength of the tube and the fin and its heat transfer performance Good, high strength, heat-resistant vibration and mechanical vibration, good thermal expansion performance, large heat dissipation area, long service life, wide temperature range and high pressure resistance. Applicable temperature range: 200-600 degrees, high temperature flue gas waste heat recovery working condition.
5. Tubular air preheater.
The tube-type air preheater is composed of many steel tubes arranged in parallel staggered rows. The two ends of the tube are welded to the tube sheet to form a cubic tube box with a certain heating surface.
The characteristics of the tube air preheater: high heat transfer efficiency, simple structure, mature processing technology, good tightness, and small tube wear.
Widely used in waste heat recovery projects in petroleum, chemical, metallurgy, electric power, environmental protection and other industries.
6. Plate air preheater.
The plate air preheater is mainly used for the recovery of waste heat of gas and gas decomposition, in industries such as grain, oil, chemical industry, and steel.
It is characterized by a compact product structure, high heat exchange efficiency, and small volume. The same area is 1/3 of the volume of the tube air heat exchanger.
