Abstract
The utility model relates to an irregular corrugated heat exchanging tube, which is characterized in that the longitudinal section of the heat exchanging tube is corrugated; the cross sections of the wave peak and the wave bottom in the longitudinal section have the same size and are in 'calabash'-shaped, and the cross sections of the wave peak and the wave bottom adopte the connection of the natural transition curves. When the fluid passes through the irregular corrugated heat exchanging tube, a boundary layer is favorable to be flushed; the heat exchanging coefficient is increased; especially, the tube wall is hardly thinned in the forming process; the condition is easier to the processing of the thick-wall tube, and the application area of the heat exchanging tube is widened.
Description
The utility model relates to a kind of heat exchange element, specifically a kind of acyclic special-shaped corrugated tube.
At present, in traditional heat transmission equipment, widely used heat exchanger tube is a light pipe.The annular corrugated heat exchanger tube of Tui Chuing was also used by large-scale popularization in the heat supply field in recent years.Traditional heat exchange light pipe heat transfer coefficient is very low, and annular corrugated heat exchanger tube heat transfer coefficient height, but it is subjected to the restriction tube wall of moulding process very thin, and caliber is difficult to moulding during less than 20 millimeters, and there is certain limitation in the field of use.In addition, the annular ripple heat exchanger tube is tube wall local reduction in forming process, the problem that is prone to lack of standardization in service afterwards.
At the deficiency that above-mentioned prior art exists, the special-shaped corrugated tube that the purpose of this utility model provides a kind of heat transfer coefficient height, applied range and easily processes.
The purpose of this utility model is achieved in that the vertical section of heat exchanger tube is corrugated, and the crest in the vertical section and identical " cucurbit " shape that all is of the cross section of trough size join for the nature easement curve between crest and the trough cross section.
The utility model has the advantages that: because heat exchanger tube is bellows-shaped, help washing away the boundary layer during by heat exchanger tube, the coefficient of heat transfer is improved greatly at fluid; Compact conformation, tube wall does not almost have attenuate in forming process, and is easier to the processing of thick-walled pipe, has widened the application of heat exchanger tube.
Below in conjunction with accompanying drawing the utility model is explained.
Fig. 1 is the utility model structural representation.
Fig. 2 is an A-A view among Fig. 1.
Fig. 3 is a B-B view among Fig. 1.
By accompanying drawing as can be known, the vertical section of heat exchanger tube is corrugated, crest 1-1 in the vertical section and the cross section of trough 1-2 all are " cucurbit " shape (seeing Fig. 2, Fig. 3), and size is identical, differ certain angle between the two, with 90 degree is the best, joins for the nature easement curve between crest and the trough cross section.Its processing method is: symmetry extrudes two convex epireliefs on light pipe, and then change certain angle (is the best with 90 degree) two indentures of symmetry extrusion (make the cross section of crest and trough be " cucurbit " shape) again on next section light pipe, with this cross arrangement, form special-shaped corrugated tube, its pipe thickness can change according to the difference of purposes, pressure.
