Formed is the vent pipe from a shape and cross-sectional area to the particular application adapted pipe over a plurality of transversely to the longitudinal extent of the Pipe has trained vent holes. In a simple way can so a fluidic connection between the individual housing areas and the environment surrounding the heat exchanger are formed so that inside the housing possibly accumulated or trapped fluid residues can be completely sucked off when needed. The accumulation of the Performance and thus the efficiency of the heat exchanger impairing gas or vapor residues can thus advantageously be counteracted. The use of the vent tube is conceivable easy.
the heat exchanger has a plurality of vent tubes, wherein each housing area in each case at least one Vent tube is provided. Can not be achieved by this arrangement just an accelerated venting process, also so in use several sealed housing areas are ensured that a mixing of the introduced into the individual housing areas media not taking place.

a heat exchanger housing divided into four sub-areas so are provide at least a total of four vent tubes, each Venting pipe is used for venting one of the four sub-areas.
per area to be vented not only but to provide a plurality of vent tubes, which also for these tubes is true that vent holes only with respect to each to be vented Range are provided.
the number of Bleed holes per vent pipe and their respective diameter in Depending on the use of the heat exchanger are designed. to Optimization of the deaeration process can reduce the number of Vent holes and their respective diameters are varied, wherein it depends, vent holes with each required cross section to be positioned in those areas of the housing to be vented, in which preferably fluid residues in the form of gas bubbles or the like form.
vent holes with each required cross section to be positioned in those areas of the housing to be vented in which preferably fluid residues in the form of gas bubbles or the like form.
Vent bores aligned which is in the context of the invention means that the vent holes so over the effective length of the Vent tube are arranged distributed that one with respect to the Use of the heat exchanger expected residue formation preferably be completely sucked for venting the heat exchanger can.
Inventive heat exchangers are manufacturer with a equipped vent tube described above. According to a special Proposal of the invention, however, an installation of inventive ventilation pipes also be retrofitted in terms of retrofitting, with a disassembly the heat exchanger or piping is not required. proposed is in this context according to the invention a method of arrangement a vent pipe in a plurality of intermediate walls having Heat exchanger in which an original for heat exchange provided pipe in the region above the longitudinal direction to bottom arranged partition is separated and the severed pipe section removed and through a provided with vent holes vent pipe is replaced.
An inventively retrofitted heat exchanger offers the already above-described advantages, wherein, unlike an already with the manufacturer a vent pipe equipped heat exchanger according to the invention Method is provided that an originally for the heat exchange provided pipe retrofitted and used in the other as a vent pipe becomes.
the Heat exchanger at least one of the preferably U-shaped Heat exchange tubes in the area above the longitudinal to bottom arranged partition wall separated.
the thus separated leg of the U-shaped Pipe is then removed and through with vent holes replaced vent pipe replaced.
This then serving as a vent pipe Part of the U-shaped tube can then be used to vent the Heat exchanger can be used in the manner described above.
vent tube For positionally safe arrangement of the vent tube is according to another Feature of the invention provided that originally for the Heat exchange provided pipe before its separation in the area above the intermediate wall is widened. This can preferably be done by means of a probe take place by means of over a defined length an end-side expansion of the in Heat exchanger remaining pipe section can be made. By expanding the tube ensures that the heat exchanger remaining pipe section after its separation not in its position slipped, but rather is held securely.
the Pipe widening the formation of a pipe receiving for the Häridde Serve ventilation pipe. In the trained in this way pipe receiving can then the vent tube is inserted and anchored. To this end the pipe receiving can be configured as a press fit. Also suitable other connectivity options, such as gluing.
FIG. 1 Shown in Fig. 1 in a schematic view of the lower portion of a Heat exchanger 1.
the heat exchanger 1 is formed by a variety of in a housing 2 arranged and combined into tube bundles U-shaped tubes 3. Provision is further more intermediate walls 4, the divide the housing 2 into separate areas 5.
the tubes 3 are flowed through by a medium to be heated, which in Flow direction 10 flows into the tubes 3 and these in the flow direction 11 leaves again.
Delivered via the introductions 17, which are also considered central trained individual introduction can be designed according to the Flow direction 12 in each portion 5 of the housing 2, a second medium, the transverse to the orientation of the tubes 3 through the areas 5 of the housing. 2 flows through and the housing through the outlet openings 6 in Leaves flow direction 13 again.
the second medium in other than can be introduced into the heat exchanger shown in Fig. 1 manner.
the invention is a Venting tube 6 provided that preferably all areas 5 of the Casing 2 protrudes and a plurality of transverse to the longitudinal extent 14 of the Pipe 6 has trained vent holes. Anything in the case 2 forming fluid residues can be sucked through this vent pipe 6 and be delivered to the surrounding the heat exchanger 1 environment.
the vent tube 6 thus creates the possibility of the housing 2 of the Heat exchanger 1 to be rid of any fluid residues, including at increasing operating time of the heat exchanger 1 a comparatively high Efficiency is ensured.
FIG. 1 shows an inventive Heat exchanger 1, in which the manufacturer already introduced a vent pipe 6 is.
the embodiment of FIG. 2 shows a a vent pipe in the aforementioned sense retrofitted heat exchanger. 1
that originally for the Heat exchange provided pipe 3 in the area above the longitudinal direction 14 arranged at the bottom intermediate wall 4 at the designated 8 point was separated and removed the separated pipe section and by a with Vent holes 15 provided vent pipe 6 has been replaced.
the rest Part 7 of the originally intended for the heat exchange tube. 3 remains in the heat exchanger 1 and is the end by a plug. 9 locked.
To determine the location of the inside of the heat exchanger arranged intermediate walls 4 can in an upstream process step an eddy current measurement are performed.
the operation of this subsequently introduced in the sense of a retrofit in the heat exchanger 1 Vent tube 6 corresponds to that, as already described for Fig. 1.
FIGS. 1 to 6 Shown in FIGS. 1 to 6 in schematic Partial view of a part of the original for the heat exchange provided pipe 3 in the region of the in Fig. 2 denoted by 8 separating point.
a first method step which is shown in FIG originally intended for the heat exchange tube 3 preferably in Area above the longitudinal direction 14 at the bottom arranged intermediate wall separated. This is shown schematically in Fig. 3 by the dashed line indicated separation point 8.
the separated pipe section 18 then removed from the heat exchanger 1 and replaced by a provided with vent holes 15 vent pipe 6.
FIG. 6 An alternative embodiment for connecting the vent pipe 6 with FIG. 6 shows the portion 7 of the tube 3 remaining in the heat exchanger. It is shown here that the end of the vent pipe 6 in the Venting tube 6 inserted connecting element 20 is provided, the for example, in the form of a cylindrical and rohragemann pointed tapered element may be formed.
the vent pipe 6 is introduced into the heat exchanger, wherein the Connecting element 20 via the tube receiving side edge of the Venting pipe 6 protrudes and so as a connection between the vent pipe. 6 and section 7 is inserted into the tube 3.
a position-safe arrangement of the Venting tube 6 relative to the section 7 of the tube 3 causes, as well as another ensures an end seal of the vent tube 6.
a position-safe arrangement of the remaining portion 7 in the heat exchanger of the tube 3 this is widened in the region of the intermediate wall 4, see FIG that an unintentional slipping of the section 7 effectively can be prevented.
the originally intended for the heat exchange pipe 3 before a separation is first widened in the region of the later separation point 8. It is thereby achieved that after a successful separation of the tube in the Heat exchanger remaining portion 7 of the tube 3 does not slip, but rather is kept secure.
the pipe extension serves as a pipe receiving, as already above described.
a process implementation according to this alternative thus provides before that for a retrofit of the vent pipe 6, first for the Heat exchange originally provided pipe preferably above the bottom arranged intermediate wall is widened. Then takes place in the area this extension a separation of the tube 3, due to the extension an unwanted slipping of the remaining in the heat exchanger 1 Part section 7 of the tube 3 is prevented.
the widened end of the Subsection 7 is also used after a separation of the tube 3 as Pipe receptacle 16, into which the introduced into the heat exchanger 1 Vent tube is fitted.
