Abstract
The utility model belongs to the improved tube casing type heat exchanger. The utility model is characterized in that the outer surface of heat exchange tubes forms a continuous nonsinusoidal wave shape, and the outer surface can be provide with umbrella-shaped water coagulating and guiding skirt edges in a welding way. The utility model has the automatic compensation function of expansion difference, vibration prevention, wear resistance, light weight, long service life and high heat exchange efficiency. The utility model is the replacing product of general tube casing type heat exchangers in industries, such as, central heating industry, thermoelectric engineering, etc. The utility model is especially suitable for using under the condition of greater temperature difference of the heat exchange medium.
Description
The utility model relates to the improvement of shell-and-tube heat exchanger.
Existing shell-and-tube heat exchanger, Chinese patent 93229213.5 etc. for example, the outer contour of its heat exchanger tube axial section the recessed or projection, contains straightway except that arc more.This heat exchanger heat exchange efficiency is used in a large number than higher.But,, when especially in thermal medium needs by heat exchanger tube, flowing through, then expansion bellow need be set on housing, with the thermal expansion difference between compensation pipe and the housing when the inside and outside medium temperature difference of pipe is bigger.This not only makes the shell structure complexity, designs the improper functional reliability that also will influence whole heat exchanger.
The purpose of this utility model is, provides a kind of under the bigger situation of the inside and outside medium temperature difference of pipe, safe and reliable, simple in structure, bearing capacity is high, the new type heat exchanger that vibrationproof is wear-resistant.
The purpose of this utility model is achieved in that and on the basis of traditional tubular heat exchanger straight steel pipe is changed into sinusoidal wave special pipe.Promptly in the shell-and-tube heat exchanger that the deflection plate that is studded with lining by housing, pull bar, heat exchanger tube, pore is formed, the outer contour of heat exchanger tube axial section is made continuous non-arcuation sine wave curve.Because sinusoidal wave special pipe under the bigger situation of the inside and outside medium temperature difference of pipe, can freely extend and compression, thereby make the thermal expansion difference between housing and the heat exchanger tube be able to automatic compensation.In addition, when heat exchanger tube is vertically installed,, umbrella condensate water guide shirt rim can be set on the heat exchanger tube appearance profile for preventing the tube wall conjunctiva.
The utility model has the advantages that the sinusoidal waveform heat exchanger tube bears external pressure ability height, the scope of application of heat exchanger is bigger; Because the function of automatic compensate for heat expansion difference is arranged, and not only the functional reliability of heat exchanger is improved, and when structural design, has also saved the housing expansion joint and has simplified the structure.
When adopting sinusoidal wave different in nature heat exchanger tube, medium produces the turbulent flow of continous-stable in pipe, the thermal boundary layer that medium forms in the pipe is constantly broken, and has strengthened the capacity of heat transmission of the interior medium of pipe.When heat exchanger tube adopted accurate cold rolling thin-wall stainless steel material, pipe surfaces externally and internally smoother was under the big temperature difference, the elongation of pipe produces wriggling with compression, make the heat exchanger tube surfaces externally and internally less scaling, condensate liquid thickness has been reduced in the condensate water guide shirt rim that heat exchanger tube has.These measures have reduced thermal resistance, have improved heat exchange efficiency, have also reduced maintenance cost thus.The lining that the deflection plate pore studs with adopts polytetrafluoroethylene (PTFE) and so on material and high resilience makes and should produce vibration heat exchanger tube under, and the lining of pore makes the thinner of deflection plate making itself.These measure vibrationproof are wear-resistant, prolonged the life-span of heat exchanger, also save the weight that metal material has alleviated heat exchanger.The utility model can improve 3～5 times of heat exchanger heat exchange efficiencies, and alternative general shell-and-tube heat exchanger is widely used in industries such as concentrated supply of heating in the city, thermoelectric engineering, petrochemical industry and pharmacy.
Further describe the utility model below in conjunction with embodiment.
Fig. 1 is the utility model structural representation.
Fig. 2 is the enlarged drawing at A place among Fig. 1.
In Fig. 1, (1) is upper tube box, and (2) are deflection plate, and (3) are the heat exchanger tube that cold rolling thin-wall stainless steel is shaped, and (4) are lower tube box, and (5) are lower perforated plate, and (6) are housing, and (7) are pull bar, and (8) are bearing.In Fig. 2, (1) is the lining made from polytetrafluoroethylene (PTFE), and (2) are deflection plate, and (3) are the sine-shaped heat exchanger tube of continuous non-arcuation for outer mold surface, and (4) are the water conservancy diversion shirt rim that umbrella is manufactured by fan-shaped foil blanking for the profile of welding on the heat exchanger.
Claims (2)
1, a kind of shell-and-tube heat exchanger has the deflection plate that housing, pull bar, heat exchanger tube, pore stud with lining, it is characterized in that heat exchanger tube appearance profile is continuous non-arcuation sinusoidal waveform.
2, shell-and-tube heat exchanger according to claim 1 is characterized in that can being welded with on the heat exchanger tube appearance profile umbrella and coagulates water water conservancy diversion shirt rim.
