To improve the flow distribution of the fluid in the externally-connected tube chambers and reduce the pressure loss thereof, two flow guide devices 13 are respectively located in the outlet externally-connected tube chamber 12 and the inlet externally-connected tube chamber 3, the two flow guide devices 13 respectively have two cavities 14 therein, multiple flow guide channels are formed between the two cavities 14 and the tube sheet 11 and communicated with the heat exchanging tubes 4, that is, the multiple flow guide channels outwardly extend from the two cavities 14 to the tube sheet 11 for forming multiple ports which are respectively corresponding to the heat exchanging tubes 4; with the decrease of the flow, cross-sectional areas of the cavities 14 of the flow guide devices 13 are continuously changed; according to influencing factors, such as the flow and the pressure of the fluid in the flow guide channels, and the resistance in the multiple heat exchanging tubes 4 which are respectively corresponding to the flow guide channels, cross sections of the flow guide channels are set to have various diameters and shapes for allowing the fluid to flow into the heat exchanging tubes 4 with uniform flow; according to characteristics of manufacturing processes or heat exchanging processes, the heat exchanging tubes 4 are able to be fixed to the tube sheet 11 through expanding joint, welding or a combination of expanding joint and welding, so as to achieve the reliable connection of the heat exchanging tubes of the heat exchanger.
  • One cavity of the outlet externally-connected tube chamber 12 is connected with a tube side outlet pipe, one cavity 14 of the inlet externally-connected tube chamber 3 is connected with a tube side inlet pipe 1; the tube side outlet pipe and the tube side inlet pipe are respectively welded to the outlet externally-connected tube chamber 12 and the inlet externally-connected tube chamber 3, for changing conventional flange sealing to welding, so as to ensure connection reliability. When the heat exchanger works, the tube side fluid flows from the tube side inlet pipe 1 to the cavity 14 of the inlet externally-connected tube chamber 3, and then into the heat exchanging tubes 4 respectively corresponding to the flow guide channels through the flow guide channels in the inlet externally-connected tube chamber 3, so as to effectively reduce the pressure loss of the fluid, for avoiding uneven flow distribution and pressure loss of the fluid in the conventional tube chambers.
  • A sieve structure 6, having multiple uniformly distributed circular holes, is located within the cavity 14 of the inlet externally-connected tube chamber 3; the sieve structure 6 has a groove, an opening of the groove of the sieve structure 6 faces towards the tube side inlet pipe 1, such that after flowing into the inlet externally-connected tube chamber 3, the tube side fluid flows through the sieve structure 6, so as to increase a main flow resistance of the tube side fluid and homogenize resistances of all directions which respectively face towards the inlets of the heat exchanging tubes; and also to uniformly distribute the fluid in the whole tube chamber 3 for finally flowing into the heat exchanging tubes, thus sufficiently utilizing heat exchanging areas of the heat exchanging tubes. According to the flow and the specific form of the tube chamber 3, sieve pores of the sieve structure 6 can be various shapes such as circular and triangular, distribution holes can be various shapes such as circular and polygonal, a diameter of the distribution holes and a distance from the distribution holes to the tube side inlet pipe 1 can be adjusted according to the specific form.
  • The split-ranging externally-connected tube chamber 9 is fixed to a split-ranging side tube sheet 8; a U-shaped flow guide apparatus 15, having multiple U-shaped flow channels therein, is located in the split-ranging externally-connected tube chamber 9, two ends of all the U-shaped flow channels extend to the split-ranging side tube sheet 8 for being respectively connected with the heat exchanging tubes 4, so that a U-shaped tube structure of the heat exchanging tubes is omitted to avoid the process of tube bending and avoid leakage after the tube wall is thinned due to the tube bending, which is convenient for setting heat exchanging tubes with various tube diameters in a same tube side to reduce a pressure drop of the tube side; the U-shaped flow guide apparatus 15 is integrally formed to avoid that the bending tube portion of the conventional heat exchanging tube needs to be determined in radius and to be manufactured respectively according to a position where every heat exchanging tube is located.
  • The flow guide devices in the outlet externally-connected tube chamber and the inlet externally-connected tube chamber, and the U-shaped flow guide apparatus in the split-ranging externally-connected tube chamber are made of a material which is optionally selected from metallic, ceramic or polyester materials according to characteristics and temperature of the heat transfer media.
  • A SK static mixer 2, located in the tube side inlet pipe 1, comprises multiple mixing components, the mixing components continuously cut the fluid medium, so that the flowing-through medium droplets are continuously dispersed and cut into smaller micelles, and then are converged between two mixing components to be mixed, the mixing components cause the fluid medium to generate radial velocity pulses, and the change in flow direction also leads to shunt and confluence, the subject convection or vortex motion can be generated while increasing the contact area to uniformly mix the fluid, so that the fluid with almost same uniform component flows into each of the heat exchanging tubes 4.
  • To strengthen the mixing of the fluid in the tubes, the heat exchanging tubes 4 are internal thread tubes, an inner wall thereof has positive and negative spiral continuous projections or grooves, which causes the fluid itself to rotate, the fluid is mixed through changing a rotational direction thereof, a position or cross section of the flow channels is changed to cause the fluid to stir itself, thus the heat exchanging is more fully.
  • A draft tube 5 is located at a shell side import and export 10 of the shell 7 for preventing a direct impact of high-speed fluid on the tube bundle at the import and export 10, so as to uniformly distribute the shell side fluid, sufficiently utilize heat transfer areas of the tube bundles at the shell side import and export 10, and meanwhile, reduce the heat transfer dead zone and avoid the fluid vibration at the shell side import and export 10.
  • Finally, it should be noted that the foregoing embodiments are merely illustrative of the technical solutions of the present invention and are not intended to be limiting thereof; although the present invention has been described in detail with reference to preferred embodiments, it will be understood by those skilled in the art that the specific embodiments of the present invention may be modified, or some of the technical features may be equivalently replaced without departing from the spirit of the technical solution of the present invention, which should be within the scope of the technical solutions claimed in the present invention.
