Abstract

The utility model provides a studded tube, relates to the design technical field of heat exchanger. The utility model discloses a parent tube, the pin fin that sets up on the parent tube periphery wall are organized, pin fin group including a plurality of row along parent tube length direction's equipartition in proper order cylinder pin fin and a plurality of row along having of parent tube length direction equipartition in proper order the portion of bending collude the shape pin fin, whenever, be listed as cylinder pin fin and every and collude the shape pin fin and separate each other and arrange. The utility model is simple and reasonable in structure, adopt cylindrical pin fin to arrange with colluding shape pin fin interval arrangement, effectively increase air turbulence, improve heat dissipation, heat exchange efficiency.

Description

A kind of studded tube

Technical field

This utility model relates to the design field of heat exchanger.

Background technology

Studded tube is to be employed heat exchanger widely, is crucial energy-saving equipment in heat transmission equipment; People utilize studded tube enhanced heat exchange to achieve good effect for a long time. The outer wall that currently used studded tube structure is usually at heat exchange base tube arranges densely covered ailhead, updates enhancing radiating effect according to differences such as the arrangement mode of ailhead, specifications; How further to improve radiating effect and be always up the Main way of radiating tube research.

Utility model content

This utility model purpose is in that for problem above, it is provided that a kind of heat exchange, the better studded tube of radiating effect.

The ailhead group that this utility model includes base tube, is arranged on base tube periphery wall; Described ailhead group includes some row along the uniform successively cylinder ailhead of base tube length direction and some row along the uniform successively hook-shaped ailhead with bending part of base tube length direction; Cylinder ailhead described in each column and the spaced layout of the hook-shaped ailhead of each column.

This utility model is simple and reasonable for structure, adopts cylindrical ailhead to be spaced layout with hook-shaped ailhead, is effectively increased air agitation, improves heat radiation, heat exchange efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As it is shown in figure 1, the ailhead group 2 that this utility model includes base tube 1, is arranged on base tube 1 periphery wall; Ailhead group 2 includes some row along the uniform successively cylinder ailhead 2-1 of base tube 1 length direction and some row along the uniform successively hook-shaped ailhead 2-2 with bending part of base tube 1 length direction; Each column cylinder ailhead 2-1 and each column hook-shaped ailhead spaced layout of 2-2.

Claims (1)

1. a studded tube, including base tube, the ailhead group that is arranged on base tube periphery wall; It is characterized in that: described ailhead group includes some row along the uniform successively cylinder ailhead of base tube length direction and some row along the uniform successively hook-shaped ailhead with bending part of base tube length direction; Cylinder ailhead described in each column and the spaced layout of the hook-shaped ailhead of each column.
