Embodiment Construction

[0016] See figure 1 , The finned heat exchange tube of the present invention and its manufacturing method are composed of a base tube 1, a fin or a fin 2. After the base tube 1 and the fins or fins 2 are assembled, the welding metal layer 4 and the fin surface plating layer 3 between the fins or the fins and the base tube are formed by hot-dip aluminum or aluminum alloy. The specific process steps of the method are as follows:

[0017] a. Assemble the fin fins and the base tube. There are two types of fin tube assembly: (1) After punching the fins one by one, install the fins on the heat exchange base tube mechanically or manually (2) Pass the long fins mechanically Wrap around the base tube. The base tube can be oval, approximately oval or circular. The fins at both ends of the assembled fin tube need to be fixed to prevent the position of the fins from changing during subsequent processes and transportation.

[0018] b. Pre-treat the finned tube. That is, degreasing and rust rem...

Abstract

The invention relates to a kind of fin heat exchanging tube and its producing method. It is used in the electric station air cooling condenser and the petrifaction air cooler. It is composed of a base tube (1) and a fin or a rib (2).Between the base tube and the fin filters the aluminium or aluminium alloy plating liquid with the method of hot dipping aluminium or aluminium alloy. After cooling, the base tube and the fin are jointed together. At the same time, the corrosion resistant aluminium or aluminium alloy film (3) forms on the fin surface. Compared with the current method of hot dipping zinc, the invention finds the substituting material of zinc relaxes the conflict of the zinc resource in short supply and reduces sharply the production cost of the heat exchanging component.

Description

Technical field: [0001] The invention relates to a heat exchange element. In particular, it relates to a finned heat exchange tube whose outer heat exchange medium is air or other gases and a manufacturing method thereof. Mainly used in equipment such as power station air cooling condensers and petrochemical air coolers. Background technique: [0002] Finned tube is the core and key component of gas heat exchanger (such as air cooler, etc.), and its performance directly affects the performance and application of heat exchanger. Among the finned tubes currently in use, elliptical tube sleeves, rectangular finned tubes, elliptical tubes wrapped around steel elliptical fin tubes, and round tubes wrapped around steel finned tubes are more common, and are widely used in air coolers and gas heat exchange in power stations and petrochemical industries. On the heat exchange equipment such as heat exchanger. The common feature of these finned tubes is that after the fins and the base tube...
