Component | Material & Design Features | Function Description |
|---|---|---|
Heat Exchange Tube Bundle | Base tube made of seamless copper tube; aluminum/copper fins attached on the surface; tube diameter and number of tube passes customizable | High-temperature fluid flows inside the tubes; fins greatly expand the heat dissipation area, improving heat exchange efficiency by 30%~50% compared to bare tubes |
Header Box / Manifold | Made of carbon steel / stainless steel; flanged connection | Ensures uniform distribution and collection of the medium; easy for inspection and maintenance |
Fan System | Axial flow fan (induced draft / forced draft optional); protection rating IP55; VFD (Variable Frequency Drive) configurable | Forces air to flow through the finned tube bundle to remove heat; induced draft design reduces environmental interference on heat exchange |
Support Frame | High-strength carbon steel welded structure; platforms, ladders, and maintenance platforms can be added upon request | Supports the main equipment body; provides space for maintenance; suitable for indoor plant or outdoor installation |
Auxiliary Components | Optional: louvers (for air volume adjustment), rain hood, anti-corrosion coating, temperature/pressure monitoring ports | Adapts to complex working conditions; enhances operational stability and service life of the equipment |

A Horizontal Radiator (also commonly referred to as a Horizontal Air Cooler / Horizontal Air-Cooled Heat Exchanger) is a highly efficient heat exchange device that uses air as the cooling medium to cool or condense high-temperature fluid inside the tubes. Its core feature is the horizontally arranged tube bundle paired with top-mounted fans. Widely used in industrial scenarios where water resources are scarce or water conservation is critical, it is an indispensable energy-saving cooling equipment in industries such as petrochemicals, coal chemicals, electric power, and metallurgy.
1. Extreme Water Saving & Low Operating Cost
Utilizing air as the cooling medium, eliminating the need for cooling towers and circulating pumps. It achieves zero water consumption, with operating costs only 1/3 to 1/5 of traditional water-cooled systems.
2. High Efficiency & Stable Performance
Features a finned-tube and forced convection design for high heat transfer coefficients. The induced-draft structure effectively minimizes the impact of sunlight and rain/snow on performance, ensuring stable thermal output with minimal fluctuation.
3. Durable, Reliable & Easy Maintenance
The main body is constructed with carbon steel with anti-corrosion coating or stainless steel, capable of handling corrosive media. The horizontal tube bundle features a simple internal structure, allowing for convenient descaling and maintenance.
4. High Degree of Customization
Customizable parameters such as the number of tube passes, fan configuration, and fin types can be adjusted to meet specific cooling requirements, installation space constraints, and media characteristics across various industries.
5. Eco-friendly, Energy-saving & Zero Secondary Pollution
With no cooling water discharge, it avoids issues such as scaling and water quality contamination, fully complying with the requirements of green industrial production.
The horizontal heat exchanger is a robust shell-and-tube unit designed for high-efficiency heat transfer between two fluids in industrial applications. Its compact horizontal layout saves floor space while ensuring easy maintenance and cleaning. Constructed from corrosion-resistant materials such as stainless steel or carbon steel, it withstands high temperatures and pressures. Ideal for HVAC systems, power plants, chemical processing, and oil refineries, this equipment delivers consistent thermal performance with minimal energy loss.
