Abstract
The invention discloses an inner guide type abnormal-shaped heat exchange pipe. The inner guide type abnormal-shaped heat exchange pipe comprises a round-section straight pipe and a plurality of radial-shaped guide members fixed in the round-section straight pipe, the round-section straight pipe and the radial-shaped guide members are tightly combined on the contact positions to form an integrated abnormal-shaped pipe, and a central axis of the abnormal-shaped pipe coincides with a central axis of the round-section straight pipe. The radial shape of the section of each radial-shaped guide member is radial from inside to outside, and the radial-shaped guide members are of radial-shaped structures distributed with the same central angle. In the central axial direction, the radial-shaped guide members are of spiral or straight-line-shaped structures around the central axis. Compared with a round pipe in the background technology, the inner guide type abnormal-shaped heat exchange pipe increases the heat exchange area multiply, improves heat exchange benefits multiply, and has a very good energy-saving and efficacy enhancement effect. Particularly, when heat exchange media in the pipe are gas, the heat exchange effect is very obvious.
Description
Technical field
The present invention relates to a kind of heat exchange element, be specifically related to a kind of inner diversion type special-shaped heat exchange tubes.
Background technology
Circular light pipe is a kind of the most frequently used heat exchange element, but its heat exchange efficiency is low.In heat exchange, for improving traditional circular light pipe heat exchange efficiency, scientific and technical personnel are studying the method and new shape structure that improves heat exchanger effectiveness always, as added various turbolators in pipe, as " spring ", or make " internally finned tube ", etc., its objective is by increasing the disturbance of the fluid media (medium) in flowing pipe, or the heat exchange area of increase pipe, improve the heat exchanger effectiveness of heat exchange element, but these methods are because increased heat exchange area is many not enough, the raising of heat exchanging efficiency is also limited, need to form by new technical method new structure and technology, on the basis of circular light pipe, significantly improve heat exchange area.
Summary of the invention
In order to solve the problem existing in background technology, the object of the present invention is to provide a kind of inner diversion type special-shaped heat exchange tubes, there is heat exchange area large, flow-disturbing effect is strong, the feature of good effect of heat exchange.
The technical solution used in the present invention is:
The present invention includes circular section straight tube and many aplysia punctata water conservancy diversion; Many aplysia punctata water conservancy diversion are fixed in the inner cylinder face of circular section straight tube, the central axes of many aplysia punctata water conservancy diversion subcenter axis and circular section straight tube.
The radial section of described many aplysia punctata water conservancy diversion is shaped as by center outside, many aplysia punctata structures that wait central angle to distribute, and ray number is 3～8.
Described many aplysia punctata water conservancy diversion are fixed in circular section straight tube inner cylinder face, and along in central axial direction, many aplysia punctata water conservancy diversion are helical form or linearity structure around central axis, and ray number is 3～8.
Compare with background technology, the beneficial effect having is:
Heat exchanger tube of the present invention is compared with the pipe of background technology, and heat exchange area is multiplied, and heat exchange benefit significantly improves, and has good energy efficiency effect.When the heat transferring medium passing through in pipe is especially gas, heat transfer effect is quite obvious.

In figure: 1, circular section straight tube, 2, many aplysia punctata water conservancy diversion.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
The present invention includes circular section straight tube 1 and many aplysia punctata water conservancy diversion 2; Many aplysia punctata water conservancy diversion 2 are fixed in the inner cylinder face of circular section straight tube 1, form a whole special piece, the central axes of many aplysia punctata water conservancy diversion 2 central axis and circular section straight tube 1.
The radial section of many aplysia punctata water conservancy diversion 2 is shaped as by center outside, many aplysia punctata structures that wait central angle to distribute, and ray number is 3～8.As shown in Figure 1, ray number is 3; As shown in Figure 2, ray number is 4; As shown in Figure 3, ray number is 6.
Many aplysia punctata water conservancy diversion 2 is fixed in circular section straight tube 1 inner cylinder face, and along in central axial direction, many aplysia punctata water conservancy diversion 2 are helical form or linearity structure around central axis.As shown in Figure 4, be helicoidal structure; As shown in Figure 5, be linearity structure.Its ray number is 3.
The present invention loads onto aplysia punctata water conservancy diversion in the straight tube of circular section, aplysia punctata water conservancy diversion and the circular section straight tube formation one of combining closely, aplysia punctata water conservancy diversion is sub or by certain lead angle (45～85 degree), rotate to form helical form around center line, or do not rotate for linearity aplysia punctata water conservancy diversion is sub, when heat transferring medium (gas or liquid) passes through pipe, effect due to aplysia punctata water conservancy diversion, increased the contact area of heat transferring medium and heat exchanger tube, the inside and outside rate of heat exchange of pipe is accelerated, when aplysia punctata water conservancy diversion is helical form, the effect of disturbance intraductal heat exchange medium is further strengthened, heat transfer effect further improves.When the heat transferring medium passing through in pipe is especially gas, heat transfer effect is quite obvious.
The above-mentioned specific embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change that the present invention is made, all fall into protection scope of the present invention.
