Convective Forced Draft System for Reactor Cooling in Oil Refineries
Product Overview
The horizontal air cooler utilizes a transverse heat exchange structure with a built-in high-efficiency fan that forces ambient cold air into the equipment. Using convection heat exchange principles, it efficiently removes heat from process fluids or equipment, achieving rapid cooling. The compact horizontal design facilitates easy installation and maintenance while adapting flexibly to various industrial space requirements.
Working Principle
Air Intake: Cold air is drawn from the external environment through the designated air inlet
Forced Air Supply: Built-in fan delivers cold air at high velocity uniformly across the heat exchange area, creating strong convection on heat exchanger surfaces
Heat Transfer: High-speed airflow closely contacts heat exchange surfaces, rapidly transferring heat to the air for efficient dissipation
Hot Air Discharge: Heated air is expelled through the exhaust port, completing the heat exchange cycle
This forced convection-based air supply significantly enhances heat dissipation efficiency, maintaining optimal temperature control even during high-load operations.
