Working Principle

The spiral finned air heat exchanger produced by our company, also known as radiator and heat sink, is the main equipment in the heat exchanger device which cools or heats the air with hot or cold medium.

Scope of application

Radiator is used in hot air heating, air conditioning, cooling, dehumidification, drying and other projects, applicable to steam or high-temperature water can heat the air, through the brine or low-temperature water can cool the air. It is used in industrial and mining enterprises, light industry, papermaking, chemical industry, national defence, textile, electric power, dairy, ceramics, hospitals, theatres and other air-conditioning systems, its structure is composed of spiral finned tubes, the use of spiral finned tubes made of a series of products, a variety of models have a different size specifications.
