Embodiment Construction

[0008] Describe in detail below in conjunction with accompanying drawing and embodiment:

[0009] The accompanying drawing is a heat exchange tube of the present invention. It includes a heat exchange tube 1, and its main points are: the heat exchange tube 1 is a threaded corrugated tube. Apparently, the threaded corrugated pipe is a corrugated pipe whose exterior is in the shape of an external thread and whose pipe hole is a corresponding internal threaded hole. The heat exchange tube in the accompanying drawings is a graphite-modified polypropylene heat exchange tube or a graphite-modified polybutene heat exchange tube. Obviously, the heat exchange tube can also be made of other materials.

[0010] In order to facilitate the welding with the tube sheet and make the welding more firm and less likely to leak, both ends of the threaded bellows in the figure are equipped with pure PP or PB straight pipe joints 2, that is, there are two ends of the heat exchange tube 1. Pure PP ...

Abstract

The invention relates to a heat exchange tube. The heat exchange tube comprises a heat exchange tube and is characterized in that the heat exchange tube is a thread corrugated tube; not only can the heat conducting area of the heat exchange tube with same length be greatly increased, but also the fluid in the tube can form turbulent flow, so that the heat exchange time is greatly shortened, the heat exchange efficiency can be improved in multiples, especially the turbulent flow formed by the fluid in the tube also can be used for washing the inner wall of the tube so as to lead the wall of the tube to be difficultly scaled, and avoid the influence of the scale on heat exchange efficiency; the heat exchange tube is easily bent and is suitable for processing a coil type heat exchanger by using single pipeline; and the corrugated tube also can buffer expansion with heat and contraction with cold of the pipeline in the use process of the heat exchanger, so that the damage to the equipment due to the factor of the linear expansion coefficient of the material is reduced. Therefore, the heat exchange tube has the advantages of large heat-conducting area, short heat exchange time, good heat exchange effect, less consumption of the heat exchange tube, resource saving, environmental protection, small equipment-occupying area, easy maintenance, difficult damage, low cost and the like, and is an update product with high cost performance, economy, practicability and obvious social and economic benefits.

Description

technical field [0001] The invention relates to a heat exchange tube. Background technique [0002] At present, the inner wall of the heat exchange tube of the heat exchanger is smooth, such as the heat exchange tube of graphite modified polypropylene tube heat exchanger, falling film absorber and graphite modified polybutylene coil heat exchanger. . Not only the heat conduction area is small, but also the fluid in the pipeline is direct current, medium fast and external slow, the heat exchange time is long, the effect is poor, the heat exchange tube consumes a lot of resources, wastes resources, the equipment occupies a large area, is easily damaged, and the cost is high. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a heat exchange tube with large heat conduction area, short heat exchange time and good heat exchange effect. [0004] A heat exchange tube, including the heat exchange tube, is character...
