Welcome to Aidear Heat Exchanger Help Center This FAQ is tailored for B2B clients in the refrigeration and industrial sectors, based on our finned tube heat exchanger product line (as detailed on our product page). These exchangers enhance heat transfer efficiency for air-to-fluid applications, ideal for HVAC, refrigeration, and process cooling. Use the search bar (e.g., "types" or "installation") for quick navigation. Questions are categorized with expandable answers. If your query isn't covered, submit a support ticket or reach our engineering team.
A: A finned tube heat exchanger uses extended surfaces (fins) on tubes to maximize heat transfer area between fluids (e.g., air and refrigerant/water), reducing size and improving efficiency. Aidear specializes in custom designs for demanding environments.
Types Offered:
Air Cooled Heat Exchangers: For outdoor/indoor air-cooled applications, with forced or induced draft fans.
Shell and Tube with Fins: Integrated fins inside/outside tubes for high-pressure fluids.
Embedded/Integral Finned Tubes: Fins mechanically bonded to tubes for superior durability.
Wound Spiral Finned Tubes: High-density fins for compact, high-performance units. Example: Wound spiral types excel in refrigeration condensers, boosting efficiency by 30%. View Types Diagram →
A: We select materials for corrosion resistance and thermal conductivity:
Tubes: Carbon steel, stainless steel (304/316L), copper, admiralty brass, or titanium.
Fins: Aluminum, copper, or stainless steel (0.1–0.5 mm thick).
Headers/Frames: Carbon steel with epoxy coating or galvanized for harsh conditions. Custom alloys available for ammonia or corrosive refrigerants. All meet ASME/GB standards.
A: Designed for B2B industrial use, they excel in:
Refrigeration Systems: Evaporators/condensers in cold storage, food processing, and pharma freezers (e.g., ammonia/R134a cycles).
HVAC & Process Cooling: Air handling units, chillers, and petrochemical heat recovery.
Other Industries: Power generation (gas turbine cooling), marine (engine cooling), and oil & gas (compressor intercoolers). Case Study: In a 500kW cold warehouse, our units reduced energy use by 25% vs. bare-tube designs.

A: Professional installation recommended (2–6 hours/unit).
Steps:
Site Prep: Level foundation, ensure 1–2 m clearance for airflow. Ambient >0°C for startup.
Mounting: Use vibration isolators; align tubes horizontally for drainage.
Piping: Flanged connections with expansion joints; flow direction per arrow (counterflow optimal).
Commissioning: Hydrotest at 1.5× design pressure; purge air from coils. Precautions: Avoid fin damage—use protective covers during handling. Installation Manual PDF →
