Passive cooling mode, used in various enclosed spaces for cooling and heat dissipation of electronic equipment, ensuring long-term efficient operation with high reliability and energy-saving efficiency

Two adjacent air flows are completely isolated, high corrosion-resistant heat exchange plates (aluminum, stainless steel) are used to realize energy transfer between different fluids. It is energy-saving ventilation in hospitals with high protection requirements, instrument cleaning and drying, low-grade air energy recovery in industrial processes, The best choice for heat pump drying and indirect evaporative cooling.

Ambient air passes through one side of an aluminum plate and contaminated air passes on the other side. Multiple plates are joined together in a special configuration to form the heat exchanger. Heated contaminated air flows through one set of air passages while the cold fresh air flows at a right angle through alternate, intervening passages. Heat is transferred from the contaminated air to the ambient air but the contamination remains in the contaminated air.
