Aluminum plate bar heat exchangers

Aluminum Plate-fin Heat Exchanger

The appearance of the aluminum plate heat exchangers have raised the heat exchange efficiency of the heat exchanger to a new level. At the same time, the aluminum plate bar heat exchangers have the advantages of small size, light weight, and can handle more than two kinds of media. At present, aluminum plate bar heat exchangers have been widely used in petroleum, chemical, natural gas processing and other industries.

Product Structure:

The aluminum plate bar heat exchangers usually consist of partitions, fins, bar, and deflectors. Fins, deflectors and seals are placed between two adjacent partitions to form an interlayer, which is called a channel. Such interlayers are stacked according to different fluid methods and brazed into a whole to form a plate bundle. The plate bundle is a plate. The core of the fin heat exchanger, together with the necessary heads, connection pipes, supports, etc., constitutes a plate-fin heat exchanger.

Working principle:

From the perspective of heat transfer mechanism, the aluminum plate bar heat exchanger is still a shoulder-arm heat exchanger. Its main feature is that it has an extended secondary heat transfer surface (fins), so that the heat transfer process takes place not only on the primary heat transfer surface (baffles), but also on the secondary heat transfer surface at the same time. The heat of the medium on the high-temperature side is poured into the medium on the low-temperature side once, and part of the heat is transferred along the height direction of the fin surface, that is, along the height direction of the fin, there is a partition to pour heat, and then the heat is convectively transferred to the low-temperature side medium. Since the fin height greatly exceeds the fin thickness, the heat conduction process along the fin height direction is similar to that of a homogeneous slender guide rod. At this time, the thermal resistance of the fin cannot be ignored. The highest temperature at both ends of the fin is equal to the temperature of the partition. With the convection and heat release between the fin and the medium, the temperature continues to decrease until the medium temperature in the middle of the fin.

Application:

Aluminum Plate bar heat exchangers have been more and more widely used in various industrial sectors due to their superior performance and mature technology.
1. Air separation equipment: The low-temperature heat exchangers such as the main heat exchanger, subcooler, and condensing evaporator of the air separation equipment adopt plate-fin heat exchangers, which can save equipment investment and installation costs, and reduce unit energy consumption.
2. Petrochemical industry: plate-fin heat exchanger has the advantages of large processing capacity, good separation effect, and low energy consumption. It has been used in ethylene cryogenic separation, synthetic ammonia nitrogen washing, natural gas, oilfield gas separation and liquefaction and other processes.
3. Construction machinery: After more than 20 years of research and practice, countries around the world have produced and used plate-fin heat exchangers in batches on automobile and locomotive radiators, excavator oil coolers, refrigerator radiators, and high-power transformer radiators. device.
