Chain type heat exchange pipe
Technical field
The present invention relates to the heat exchanger tube for heat exchanger, is a kind of chain type heat exchange pipe specifically.Change the X-section of media flow in heat exchanger tube, enhance the heat exchange efficiency of heat exchanger tube.
Background technology
The heat exchanger tube be generally used in heat exchanger is round tube.Because the heat exchange sectional area of round tube is large, affect heat exchange efficiency.For addressing this problem, in disclosed technology, it makes cross ellipse tube tee section heat exchanger tube according to certain rule on same heat exchanger tube, and each pipeline section of its staggered variable-section tubular is corresponded to each other connection.The staggered elliptic cross-section heat exchanger tube of above-mentioned design, compared with traditional approach, improves for heat transfer coefficient.But each ellipse cross section pipeline section that interlocks directly connects, easily produce higher flow resistance.
Summary of the invention
In view of above-mentioned present situation, the object of this invention is to provide a kind of chain type heat exchange pipe, by the extension nature transition of each intersection pipeline section, decrease flow resistance, enhance heat transfer efficiency.
Technical solution of the present invention is: a kind of chain type heat exchange pipe, comprises heat exchange pipe body; Wherein, described heat exchange pipe body has the Multisection lock chain type pipeline section body by interleaved distribution, the connection often saved between chain type pipeline section body is transition and extends interconnection.Therefore, extend by transition the design being crossed as pipeline section body and eliminate flow resistance between each pipeline section, enhance flow velocity, avoid the generation of fouling, effectively improve heat exchange efficiency.
In the present invention, involved chain type pipeline section body each other transition extends intersection in 90 °.Be convenient to the reasonable Arrangement of multiple chain type heat exchange pipe in heat exchanger, minimizing takes up room.
The good effect that the present invention has is: because have employed chain type heat exchange pipe, and for transition extends interconnection between each pipeline section, not only there is flow resistance little, but also the flow velocity of medium can be increased, reduce the generation of heat exchanger tube encrustation, substantially increase heat exchange efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described.
A kind of chain type heat exchange pipe as shown in Figure 1, comprise heat exchange pipe body, heat exchange pipe body described in the present embodiment has the Multisection lock chain type pipeline section body 1 by interleaved distribution, the connection often saved between chain type pipeline section body 1 is transition and extends interconnection, and the straight tube 2 at chain type pipeline section body 1 two ends is installation ends.Like this, heat exchanger tube is chain type pipeline section body, to each other for transition extends interconnection, is conducive to eliminating the flow resistance between each chain type pipeline section body 1.In actual applications, consider that involved multiple chain type heat exchange pipe reasonable Arrangement are in heat exchanger, minimizing takes up room.Chain type pipeline section body 1 described in the present embodiment each other transition intersects in 90 °.The two ends body 2 of chain type heat exchange pipe segment body 1 of the present invention retains circular pipeline section, is convenient to the soldered of the circular hole of same heat exchanger tube sheet and connects.
