IHI TX Intercooler

1. Product Overview: Precision Heat Exchange Equipment Based on Thermodynamics

The IHI TX Intercooler is a high-efficiency intermediate cooling device developed for industrial air compressor systems. Its core function is to reduce compressed air temperature through heat exchange processes, improving system efficiency and reliability. This product belongs to the shell-and-tube or plate-fin heat exchanger category, achieving efficient heat transfer through optimized fluid dynamics design.

1.1 Structural Features and Working Principle

The product features dual-flow channel design: high-temperature compressed air flows through tube channels or fin passages while coolant (water/air) moves counter-currently in the shell side. Key components include:

• Heat Exchange Core: Aluminum alloy plate-fin structure with 0.1-0.3mm fin thickness and 800-1200m²/m³ specific surface area, delivering 30%+ higher efficiency than traditional shell-and-tube designs.
• Sealing System: Graphite gaskets with laser welding technology withstand 3.5MPa pressure with ≤1×10⁻⁸ Pa·m³/s leakage rate.
• Flow Distributor: Patented guide vanes ensure uniform fluid distribution with Temperature Field Uniformity (TFU) ≤0.15.
