air cooler

1. Product profile

air coolerIt is the ambient air as the cooling medium, cross sweep outside the fin tube, so that the high temperature process fluid in the pipe is cooling or condensation equipment, referred to as "air cooler".

In the heat exchange equipment of oil refineries and petrochemical plants, air coolers become an indispensable type of equipment. In the chemical industry, electric power, metallurgy and other industries, the air cooler is also widely used.

Air cooler is used for motor ventilation cooling system, air conditioning system, air compressor cooling system, and can also be used as parts of large fan coil units.

2. Model meaning

Standard rolled wing sheet type

The air cooler is mainly composed of tube bundles, fannerAnd architectureThree parts. The tube bundle includes the heat transfer pipe, pipe box, side beam and cross beam, etc. It can press horizontal type, vertical type two kinds of basic form arrangement. Among them, the horizontal layout heat transfer area is large, the air distribution is uniform, and the heat transfer effect is good. To offset the effect of the lower thermal delivery coefficient on the air side, the outer wall of the optical tube is usually used. The fin tube, as a heat transfer tube, can expand the heat transfer area. The fin tubes are arranged in layers, and their two ends are connected to the pipe box by welding or expansion method. Drain pipe is generally 3~8 rows. The tube bundle series is up to 12 meters. The outer diameter of the light tube is often 25 mm and 38 mm, the height of the fin is generally 12~15 mm, and the width of the tube is 100~3000 mm. The fin tube is the core element of the air cooler, and its form and material directly affect the performance of the equipment. The pipe can be made of carbon steel, copper, aluminum and stainless steel; the fin material is determined by the environment and manufacturing process, mostly industrial pure aluminum, copper or stainless steel in high corrosion requirements or special manufacturing conditions. The fins can be arranged either horizontally or vertically.fin tubeThe basic forms are: winding sheet type, chip type, rolling sheet type, sleeve sheet type, wafer type, elliptical tube type, turbulent type (including spoke type, slot shape and corrugated shape, etc.). The structure of the pipe box mainly has flange type, pipe blocking type and assembly tube type. The former is generally used for medium and low pressure, and the latter two are used for high pressure. To accommodate the thermal expansion of the tube bundle, one end box is not fixed and allowed to shift along the tube length. The ventilator usually uses the axial flow ventilator。
