Aluminum Foil Automatic Perforating Machine

Aluminum Foil Automatic Perforating Machine, the hole position and quantity are upon the client’s request.

Aluminum Foil Automatic Perforating Machine is used to produce heat exchanger perforated fins. First, the aluminum foil/ copper foil/ SS foil is perforated by a perforating machine. Then the perforated foils are formed into perforated fins by a fin machine. The perforated fins are mainly used for air-conditioner radiators, condensers, automobile intercoolers, radiator air coolers, air separation heat exchangers, and more.DAG supplies the full set of heat exchanger fin solutions
from metal foil perforating machine, fin forming machine, cutting fin machine and fin molds, etc.

Main functions of perforated fins

1. Enhance heat exchange, improve heat dissipation/ cooling efficiency

When air flows through the small holes in the fins, it is divided and disturbed, breaking the static air layer on the surface and increasing the contact strength between the air and the aluminum foil. The heat exchange efficiency is significantly improved compared to ordinary smooth fins

2. Reduce wind resistance, lower fan load

The dense holes make the air flow penetration better, reducing ventilation resistance and resulting in less power consumption for the fan and lower operating

3. Distribute condensate water, prevent water accumulation and condensation

In certain conditions, such as air-conditioning evaporators, condensate water will be generated. The small holes can quickly guide and drain the water, avoiding water droplets adhering to the surface of the fins, blocking the airflow, and breeding mould.

4. Reduce the weight of heat exchanger/cooler/radiator

Overall, the holes are reduced, which leads to less material usage. The fins are thinner and lighter, resulting in a reduction in the overall weight of the equipment and a decrease in production costs.

5. Noise reduction

When the airflow passes through the micropores, it becomes more stable, which can slightly reduce the overall operating noise of the machine

6. Uniform air distribution

The airflow distribution is more uniform, resulting in more consistent temperatures and heat exchange effects throughout the heat exchanger.

Distribution Fin Cutting Machine for Plate Fin Heat Exchanger

The distribution fins are one of the important brazed components of the aluminum plate-fin heat exchanger. The cutting of the distribution fins is a key process in the manufacturing of the aluminum plate-fin heat exchanger. The production quality of the distribution fins directly affects the assembly quality and brazing quality of the core body. Therefore, mastering the cutting process of the distribution fins for aluminum plate-fin heat exchangers is a crucial step in improving the quality of aluminum plate-fin heat exchangers. However, the guideplates/ distribution fin isn’t regular rectangles that can be directly cut by a fin machine but are parallelograms, trapezoids, etc., as shown in the distribution fin type table below. How to cut the irregular guide plates/ distribution fins?

Custom Fin Molds for Fin Stamping Machine

The Fin Machine can produce all kinds of Heat Exchanger Fins, which must be matched with corresponding fin moulds. Main fin types are offset fin, straight fin, perforated fin, louvred fin, and wavy fin. Fin type and pitch are usually fixed by fin moulds. Different fin specifications need different moulds, so there are usually many sets of fin moulds to accompany a fin machine.

If you want to produce fins, please supply your fin specification, including fin type, fin material, fin height, pitch, fin thickness, and fin flow length. We’ll hereby offer you a set of optimised finforming solution incuding fin machine, fin mould and operation instruction.

Core Builder Machine for Plate Fin Heat Exchanger

Core builders/ plate fin radiator core assembly machines have been widely used in heat exchanger factories for aluminum plate fin heat exchangers, plate bar coolers, and radiators, which greatly speeds up the core assembly efficiency and increases the loading capacity of the brazing furnace. The plate fin cooler core assembly machine is suitable for assembling plate bar cooler cores of various specifications. The core builder for plate bar coolers can easily and flexibly adjust the length, width and height of the cooler core. The Core Builder for Plate Fin Heat Exchanger can save manpower and time, improve production efficiency, and reduce furnace loading to save energy consumption.

Plate Fin Heat Exchanger Core Assembly Machine

For vacuum brazing aluminium plate fin coolers, the traditional radiator core assembly method is to adopt the WDH adjustable fixed high baffle on platform. After core assembly, professional personnel perform core trimming and use heavy stainless cast steel clamps and long bolts and nuts to fix cores, which is time-consuming and labour-intensive, and cannot make full use of the heating space of the vacuum brazing furnace.

In order to improve the efficiency of core assembly and reduce energy consumption, Core Assembly Machine technology has gradually entered the field of aluminium exchangers, plate fin coolers, and radiators, which greatly speeds up the core assembly efficiency and increases the loading capacity of the brazing furnace.

The plate fin builders have been widely used in plate fin Heat Exchanger factories with the main advantages.

1. Finish the core assembly and shaping in one place

2. Save core-shaping time and avoid moving the core many times.

3. Increase the furnace’s loading ratio.

4. Improve the brazing quality.

Core Assembly Machine, perfectly customized to your product size requirements.

Plate Fin Heat Exchanger Core Assembly Fixture

Plate Fin Core Assembly Fixtures are used to fix the plate bar cooler cores after finishing the core assembly. The core fixtures are lightweight, small in volume and can be used repeatedly. The lightweight brazing fixtures are matched to the plate bar Core Assembly Machine

With the automatic tightening force from the assembly machine, the fixtures can fix the cores well. If you don’t use the core assembly machine. please choose another kind of heavy-duty core fixtures; the fixtures need to tighten the core depending on the fixture’s own gravity. After fixing the cores, the plate fin cooler cores with fixtures will be brazed in a vacuum brazing furnace, so the core jig and fixtures are also called plate fin core brazing fixtures.

We can make all kinds of standard and non-standard Vacuum Brazing Furnace Fixtures to clients’ demands.

Heat Exchanger Supersonic Cleaning Machine

The gas-phase ultrasonic cleaning machine is a sealed type with a manipulator-driven transportation rack, loading by special material baskets, step-type conveying cleaning technology and a pneumatic elevator to transport material. Using organic solvent such as trichloroethylene as the cleaning medium to degrease the surface of the workpiece. Then having freeze-drying. The supersonic
cleaner is suitable for the cleaning of the heat exchanger parts.

The principle of the gas-phase cleaning machine is as follows. When the solvent is heated, the steam forms the gas phase zone. In this area, the oil on the surface of the workpiece is dissolved and washed by steam. When the steam condenses, the dirt along with the grease falls back into the tank to become the cleaning fluid. Then, the cleaning fluid is heated and vaporised into steam to clean the workpiece. This continuous cycle ensures the workpiece is always surrounded by the steam of cleaning fluid, which overcomes the problem of contaminated cleaning fluid in the past common cleaning process.
