Description
Technical Field
The utility model belongs to the technical field of the cooling finned tube, concretely relates to high pressure resistant finned tube air cooler structure.
Background
The finned tube is a heat exchange element, and is used for improving heat exchange efficiency, and the surface area (or inner surface area) of the heat exchange tube is increased by adding fins on the surface of the heat exchange tube, so that the purpose of improving the heat exchange efficiency is achieved.
The finned tube is used as a heat exchange element and works under the working condition of high-temperature smoke for a long time, for example, the finned tube for a boiler heat exchanger has a severe using environment and is in a corrosive atmosphere at high temperature and high pressure, so that the finned tube is required to have high performance indexes including corrosion resistance, wear resistance, low contact thermal resistance, high stability and dust deposition resistance. The prior rotary fin tube is generally fixed on a frame by welding a copper forming tube through a fixing sheet by means of brazing or high-frequency welding.
The general processing of the brazing spiral finned tube is carried out in two steps: firstly, winding the steel strip plane on the outer surface of the pipe in a spiral line mode perpendicular to the axis of the pipe, welding two ends of the steel strip on the steel pipe for fixing, and then welding the steel strip and the steel pipe together by a brazing method in order to eliminate the gap at the contact part of the steel strip and the steel pipe. However, this method is expensive, and another method is used, in which the steel strip wound pipe is put into a zinc bath to be subjected to hot dip galvanizing integrally. The whole hot galvanizing plating solution can not well penetrate into a tiny gap between the fin and the steel pipe, but a complete galvanizing coat is formed on the outer surface of the fin and the outer surface of the steel pipe. The integral hot-dip galvanized spiral finned tube is limited by the thickness of the galvanized layer (when the galvanized layer is thick, the firmness of the zinc layer is poor, the zinc layer is easy to fall off), and the zinc liquid cannot completely permeate into the gap, so that the bonding rate of the fin and the steel tube is still not high. In addition, zinc has a lower heat transfer coefficient than steel (about 78% of steel), and therefore has a lower heat transfer capability. Zinc is highly susceptible to corrosion in acids, alkalis and sulfides, and thus, the use of the galvanized spiral fin tube is not suitable for manufacturing an air preheater (recovering waste heat of boiler flue gas).
The high-frequency welding spiral finned tube is one of the most widely applied spiral finned tubes, and is widely applied to the industries of waste heat recovery in the power industry, the metallurgy industry, the cement industry, the petrochemical industry and the like.
However, the existing new air cooler with two rows of horizontally arranged finned tubes generally adopts the way that an upper finned tube and a lower finned tube are connected through a 180-degree elbow according to a tube arrangement rule, the connected finned tubes need to be welded at the connecting ends, and the welding of the connecting ends is not performed by using a forming tube in the traditional technical scheme.
