Definitions
- the invention relates to a heat exchanger tube with a Inner tube and an outer tube, of which at least one tube has rib-like deformations between the inside and Outer tube at least one essentially over the axial length helical circumferential flow channel form.
- Such a heat exchanger tube is already from the US 3,777,343 known.
- the heat exchanger tube shown and described there has the major disadvantage, however, that it is not can be dismantled for cleaning purposes. Rather, here two pipes inserted into each other and clamped tight, whereby the inner tube then in the outer tube to form rib-like Deformation is twisted. This results in an unsolvable Connection of both pipes to each other. Furthermore can by twisting the inner tube within the Outer tube no defined flow channel can be produced.
- the object of the invention is now a new one To create heat exchanger tube, which despite simple manufacture has precisely dimensioned flow channels and is easy to disassemble, especially for cleaning purposes.
- the heat exchanger tube according to the invention has the essential Advantage that their components, namely inner tube and Outer tube can be made separately and then through axial and / or helical relative movement to each other brought into an operational position to each other can be. It is exactly the same after a certain period of operation possible the two components on simple Way to separate and clean. This has in particular great benefits to the food industry as well for pharmacy and medical technology.
- the interior and the outer tube each on rib-like deformations in addition to the at least one flow channel, one in parallel running, flat as well as from colliding Form comb surfaces sealing zone, the Sealing zones of inner and outer pipe after a relative movement of the tubes by at least the axial extent of the Sealing zones in each opposite, the flow channel Immerse the forming areas in a freely movable manner.
- advantageous results Way at least one completely delimited flow channel, the from inner peripheral surface areas of the outer tube and outer peripheral surface areas of the inner tube is formed, wherein the flow channel or channels ultimately through both sides spaced comb surfaces from inside and Outer tube (sealing zones) are formed.
- a substantially rectangular flow channel In a further advantageous embodiment of the invention at least form the rib-like deformations a substantially rectangular flow channel.
- the rectangular flow channel has fluidic Advantages because the distance of the main heat transfer surfaces, these are the long surfaces of the rectangular flow cross-section, are relatively small. This is according to the theory the heat transfer paths to the transfer medium relative short. Especially with very viscous media, where the swirl is not sufficient, is the minor Distance of the main transmission surfaces very advantageous because nevertheless a relatively good heat exchange still takes place can.
- a further advantageous embodiment of the invention is the pipe arrangement consisting of inner and outer pipe provided with an inner and an outer cladding tube.
- This is now possible in countercurrent or cocurrent a liquid flushing the heat exchanger tube through the System to send, so that the heat exchanger tube in one liquid-carrying annular gap.
- the outer contour of the outer tube or the inner contour of the inner tube additionally a turbulent flow within the Ring channel, which is also advantageous for heat exchange is.
- This turbulent flow can be part of another Embodiment can be increased in that the inner and / or outer cladding tube has profiles that cause an increase in the degree of turbulence.
- inner and outer tube markings have, for example, by a common Be formed.
- the invention further relates to a method for Installation of a heat exchanger tube according to claim 1 or one of the following claims.
- a heat exchanger is included denotes the reference number 10.
- connection blocks 11 on both sides, via which the supply or discharge of the cooling / heat transfer medium and the product.
- the heat exchanger 10 has an inner tube 12 (see FIG. 2) and an outer tube 13 (see FIG. 3), as described below can be put together.
- the inner tube 12 has a helical, outward rib-like deformation 15, a comb surface 14 is formed.
- the outer tube 13 with an inward rib-shaped deformation 16 provided, which are also arranged helically and has inwardly projecting comb surfaces 17. While in the inner tube 12 between the projecting outwards Comb surfaces 14 each form the flow channel 18 Areas 19 are present, the outer tube 13 has between areas 20 forming the flow channel 18 to the comb surfaces 17 on. This can be seen particularly well in FIG. 4. There the comb surfaces 14 and 17 are in the function of sealing surfaces clinging to each other while the areas 19 and add 20 to the flow channel 18.
- FIG. 5 shows a heat exchanger tube 10, which of an inner cladding tube 21 and an outer Cladding tube 22 is surrounded. While doing this the flow channel 18 is intended for the transport of a product, the Annular gap 23 for transporting a heat / coolant used.
- the Heat exchanger tube 10 clearly recognize that the comb surfaces 14 and 17 lie close together, so that a closed helical flow channel 18 arises.
- FIG. 7 now shows one for steam operation suitable heat exchanger 10, in which only an outer Cladding tube 22 is provided, the inner tube 12 and Outer tube 13 has a significantly enlarged diameter.
- the flow channel 18 for the product provided, the annular gap 23, as well as an interior 26, through which steam flows.
- a heat exchanger 10 with an inner profiled Cladding tube 27 and with an outer profiled cladding tube 28 is shown in Fig. 8.
- an inner tube 29 is a Heat exchanger 10 shown, which three parallel Has flow channels 18 ', 18' 'and 18' ''.
- flow channels 18 ', 18' 'and 18' '' are arranged in separate flow channels 18 ', 18' 'and 18' '' to transport different products.
- FIGS. 11 and 12 are again first an enlarged view of a heat exchanger 10 according to 4, the inner and outer tubes 12, 13 each have a bead 30, 31. With the beads 30, 31 are markings of the inner tube 12 and the Outer tube 13 through which a precise mutual assignment the pipes can be secured. If the assignment is correct Beads 30, 31 to each other, is the operating position of the Pipes 12 and 13 reached, that is, the comb surfaces 14 and 17th lie on top of each other.
