What is an air radiator? What is the product structure? What technology and product knowledge does it have? Friends in the industry must know as the name implies; but for friends who have not touched, must be very strange, may not know the product parameters of air radiator knowledge; below, the Qingli official website to friends to make a rough product knowledge introduction:

Air radiator is a high-efficiency finned tube as a heat transfer element, steam or other fluids (thermal oil, water, etc.) as a working medium, air as another working medium, through the finned tube to strengthen heat transfer, to achieve the purpose of heating, cooling the working medium in the tube or heating, cooling the air in the tube.

The scope of use of air heaters:

1. Forming machines: Forming machine, coating machine, printing machine, printing machine, dry cloth machine and other fixed size radiators, generally for the production line.

2. Drying room and oven: brick room or large metal box, material parked inside drying, fan and radiator can be built-in or outside.

3. Tunnel furnace drying furnace: long and large metal box, built-in various forms of chain conveying materials, materials from the import to the export to complete the drying process, generally for pipeline production.

4. Air drying: powder, fine particles drying, need to be equipped with cyclone separator, hoist, etc. can work, generally for the production line.

Technical parameters of air radiator industry:

The range of net ventilation velocity of A. flowing through the air radiator is generally in the range of

3m/s to 8m/s, design 5m/s.

B. net ventilation area and windward area ratio:

Aluminum rolling pipe: 0.55, winding tube 0.6, copper tube string aluminum 0.532.

Net ventilation area = x ratio of windward area

C. The forward wind speed of the condenser of the central air-conditioning hood should not exceed 3 m/s. If it exceeds this range, the water baffle should be added.

Limit heat dissipation temperature: about 30 C

For example, when the steam temperature is 170 degrees, the temperature of the air passing through the radiator can reach 140 degrees.

D. formula for wind speed:

V= air volume flow / net ventilation area x3600

The phase transition temperature of E. steam from gas to water is 100 C, and vice versa 100.

F. high temperature flue gas waste heat recovery temperature generally dropped to 120 degrees. High temperature waste heat recovery temperature is unlimited.

G. steam traps in general should be set up steam traps, steam traps play a role in blocking drainage.

H. The valve used to control the steam in steam pipeline is the globe valve (cast iron material), the valve used to control the heat conduction oil in the heat conduction oil pipeline is the globe valve (carbon steel quality, because the temperature of the heat conduction oil is high), and the gate valve is used in the hot water pipeline.

I. Pressure relief valve (piston type pressure relief valve): as indicated by the pressure difference of 2 kg, if 7 kg saturated steam passes through this pressure relief valve, the saturated steam pressure level is 5 kg.

Air radiator, whether in the industrial field, or in the daily life of many products drying, can be used; Rongli air radiator, with 10 years of experience, professional focus, engineering case rich, has been unanimously recognized by the majority of customers; look forward to working with the majority of customers, and create good results; if need to learn more air Radiator product technical parameters knowledge, real-time attention to the company's official website, but also can call: 020-28140958 one-to-one consultation services, for your troubles.
