Aluminum Evaporator Manufacturing | Isso Mak
Aluminum evaporators are key components in a variety of industrial applications, particularly in refrigeration and air conditioning systems. They are responsible for heat transfer and the conversion of a liquid refrigerant into vapor. Some information about the production process of aluminum evaporators:
  1. Material Selection: Aluminum is a preferred material in evaporator manufacturing due to its excellent thermal conductivity, light structure and corrosion resistance. Typically, aluminum alloys such as AA3003 or AA1100 are chosen for their desirable properties.
  2. Tube Formation: The production process begins with the manufacture of aluminum tubes. These tubes are typically extruded or drawn to achieve the desired dimensions. In order to increase the heat transfer efficiency, the inner surface of the pipes must be smooth.
  3. Fin Production: Aluminum fins are used to increase the surface area available for heat transfer. They are usually made by a process called roll forming, in which aluminum sheets are passed through rollers to create a fin pattern. The wings are then cut and expanded to the desired spacing.
  4. Assembly: When the tubes and fins are ready, they are combined to form the evaporator core. The tubes are inserted into the slits of the fins, creating a solid bond. The assembly process may involve the use of mechanical expansion or adhesive bonding techniques to ensure a secure connection.
  5. Cooler Circuit: Cooler circuit must be installed in evaporator manufacturing. This includes connecting the inlet and outlet headers to the evaporator core. The headers provide the necessary connections for the refrigerant flow by allowing liquid refrigerant to enter the evaporator and vapor refrigerant to exit the evaporator.
  6. Quality Control: Throughout the manufacturing process, quality control measures are implemented to ensure the reliability and performance of aluminum evaporators. These may include inspections for pipe and fin dimensions, visual checks for any defects or damage, pressure testing to identify leaks, and general functionality testing.
  7. Surface Treatment: Surface treatments such as coating or anodizing can be applied to further increase the corrosion resistance and durability of the evaporator. These processes form a protective layer on the outer surface of the evaporator, protecting it against environmental factors.
  8. Final Assembly: After the evaporator core is manufactured, it can be integrated into a larger system such as a refrigeration or air conditioning unit. This final assembly step involves connecting the evaporator to other components such as the compressor and condenser to complete the system.
