Abstract
The utility model relates to a multi-head screw heat exchange pipe. The utility model is used for exchanging heat for the refrigeration industry, the metallurgy industry, the mechanical industry, the boiler making industry, etc. The utility model comprises a heat exchange pipe body 1. The utility model is characterized in that an inner pipe wall and an outer pipe wall 1.1 and 1.2 of the heat exchange pipe body 1 respectively form a multi-head screw shape. The liquid is continuously turned and flowed in the utility model, and the heat-transfer efficiency of the utility model is more than five times faster than that of light pipes. Thus, the utility model can improve the heat exchange efficiency.
Description
Technical field:
The utility model relates to a kind of heat exchanger tube, especially relates to a kind of multi-head spiral heat exchanger tube.Be widely used in freezing, the heat exchange of industry such as metallurgy, machinery, boiler manufacturing.
Background technology:
Along with improving constantly of industry technologies such as refrigeration, metallurgy, machinery, boiler manufacturing, the requirement of exchange heat pipe is also in corresponding raising.Traditional heat exchanger tube has light pipe and gear piece pipe etc.The light pipe heat exchange efficiency is low.Though gear piece pipe heat exchange efficiency increases, be 2～2.5 times of light pipe, heat exchange efficiency also is not very high.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of heat exchange efficiency higher multi-head spiral heat exchanger tube.
The purpose of this utility model is achieved in that a kind of multi-head spiral heat exchanger tube, comprises heat exchange pipe body, is characterized in that the inside and outside tube wall of heat exchange pipe body is the multi-head spiral shape.Liquid is sustainable in pipe to roll mobilely, and its heat transfer efficiency is more than five times of light pipe.Therefore the utility model can improve its heat exchange efficiency greatly.
Description of drawings:
Fig. 1 is an outside drawing of the present utility model.
Fig. 2 is the A-A cut-away view of Fig. 1.
The specific embodiment:
As Fig. 1～2, the utility model is a kind of multi-head spiral heat exchanger tube.It comprises heat exchange pipe body 1, is characterized in that the inside and outside tube wall 1.1,1.2 of heat exchange pipe body 1 is multi-head spiral shape (twisted shape).A number of multi-head spiral can be from three to 20, or more than 20.
Spiral heat exchange tube external diameter of the present utility model is from ￠ 10mm～￠ 20mm.Material can be stainless steel tube, iron pipe or copper pipe etc.
