Abstract
The utility model discloses an inner petal special-shaped heat exchange tube. The inner petal special-shaped heat exchange tube comprises a circular cross section straight tube and a plurality of petal-shaped flow guiders. The petal-shaped flow guiders are fixedly connected to the inner cylindrical face of the circular cross section straight tube, and the central axes of the petal-shaped flow guiders coincide with the center axes of the circular cross section straight tube. The radial cross sections of the petal-shaped flow guiders are in a petal-shaped sealed structure, or in the central axis direction, the petal-shaped flow guiders are in a spiral-shaped or straight-shaped structure around the central axes. According to the inner petal special-shaped heat exchange tube, compared with a circular tube in the background technology, the heat exchange area is increased by multiples, the heat exchange efficiency is improved by multiples, and a good energy-saving and efficiency enhancement effect is achieved. Particularly, when heat exchange media in the tube are changed to be gas, the heat exchange effect is rather obvious.
Description
Technical field
The utility model relates to a kind of heat exchange element, is specifically related to a kind of interior petal 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 improve heat exchanger effectiveness always, as added various turbolators in pipe, as " spring ", or make " internally finned tube ", etc., its objective is the disturbance by increasing the fluid media (medium) in flowing pipe, or the heat exchange area of increase pipe, improve the heat exchanger effectiveness of heat exchange element with this, but the heat-transfer surface that these methods increase is many not enough, the raising of heat exchanging efficiency is also limited, need to form new structure and technology by new technical method, 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 purpose of this utility model is to provide a kind of interior petal special-shaped heat exchange tubes, has heat exchange area large, and flow-disturbing effect is strong, the feature of good effect of heat exchange.
The technical solution adopted in the utility model is:
The utility model comprises circular section straight tube and multiple petal water conservancy diversion; Multiple petal water conservancy diversion are fixed in the inner cylinder face of circular section straight tube, the central axes of multiple petal water conservancy diversion subcenter axis and circular section straight tube.
The radial section of described multiple petal water conservancy diversion is shaped as multiple petal enclosed constructions, and petal number is 3～8 lobes.
Described multiple petal water conservancy diversion is fixed in circular section straight tube inner cylinder face, along on central axis direction, and petal water conservancy diversion or be helical form or linearity structure around central axis, petal number is 3～8 lobes.
Compared with background technology, the beneficial effect having is:
Compared with the pipe of heat exchanger tube of the present utility model and background technology, heat exchange area is multiplied, and heat exchange benefit significantly improves, and has good energy efficiency effect.In the time that the heat transferring medium passing through in pipe is gas, heat transfer effect is quite obvious especially.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model comprises circular section straight tube 1 and multiple petal water conservancy diversion 2; Multiple petal water conservancy diversion 2 are fixed in the inner cylinder face of circular section straight tube 1, form an overall special piece, the central axes of multiple petal water conservancy diversion 2 central axis and circular section straight tube 1.
The radial section of multiple petal water conservancy diversion 2 is shaped as multiple petal enclosed constructions, and petal number is 3～8 lobes.As shown in Figure 1, petal number is 3; As shown in Figure 2, petal number is 4; As shown in Figure 3, petal number is 5.
Multiple petal water conservancy diversion 2 are fixed in circular section straight tube 1 inner cylinder face, along in central axial direction, and petal water conservancy diversion or be helical form or linearity structure around central axis.
As shown in Figure 4, be linearity structure, its petal number is 5.As shown in Figure 5, be helicoidal structure, its petal number is 4.
The utility model is loaded onto petal water conservancy diversion in the straight tube of circular section, petal water conservancy diversion and the circular section straight tube formation one of combining closely, petal water conservancy diversion is sub or rotate to form helical form around center line by certain helical angle (45～85 degree), or do not rotate for petal water conservancy diversion of linearity, in the time that heat transferring medium (gas or liquid) passes through pipe, due to the effect of petal water conservancy diversion, increase the contact area of heat transferring medium and heat exchanger tube, the inside and outside rate of heat exchange of pipe is accelerated, in the time that petal water conservancy diversion is helical form, the effect of disturbance intraductal heat exchange medium is further strengthened, heat transfer effect further improves.Compared with common pipe, heat exchange area is multiplied, and heat exchange benefit significantly improves, and has good energy efficiency effect.In the time that the heat transferring medium passing through in pipe is gas, heat transfer effect is quite obvious especially.
The above-mentioned specific embodiment is used for the utility model of explaining; rather than the utility model is limited; in the protection domain of spirit of the present utility model and claim, any modification and change that the utility model is made, all fall into protection domain of the present utility model.
