Definitions
- Probe housing and probe device with a sensor and a
- the present invention relates to a probe housing and a probe device with a sensor and a probe housing.
- sensors are used in probes that are minimally invasive and placed directly in the hot gas environment or at its edge .
- the probe bodies have cooling devices that can be used to cool the probe bodies and the sensor technology they contain.
- Such a probe body is known from DE 10 2012 216 267 A1, which consists of a probe housing with cooling channels, a probe head being exchangeable in order to adapt the system to different sensors. Since the probe head has to be cooled, a complex coupling design is necessary to direct the cooling medium into the probe head. Furthermore, in the previously known probe, it is provided that a flushing medium can be used to clean the sensor exit surface of the probe.
- the probe has a large number of channels, which are distributed evenly in the circumferential direction. Some of these ducts are used as cooling ducts, while other ducts are used to supply purge air.
- the previously known construction Due to the construction with a replaceable probe head, the previously known construction is relatively large and expensive or complex, thus prone to leaks.
- one goal when measuring hot gas systems is to influence a hot gas flow as little as possible in order to obtain measurement results of the highest possible quality. Therefore, it is desirable to make a probe as small as possible.
- the hot gas environment can also be influenced due to the flushing air fed to the sensor outlet.
- flushing takes place concentrically, as a result of which increased contamination can occur at the sensor outlet due to the formation of vortices.
- the probe head in the previously known probe is permanently exposed to the hot gas, so that even at times when no measurement is taking place, there is thermal stress on the components and the contamination process can progress. As a result, increased cooling and rinsing requirements are necessary with such a design.
- the probe housing according to the invention is defined by the features of claim 1.
- the probe device according to the invention is defined by the features of claim 15.
- the probe housing according to the invention for accommodating sensors has a plurality of coolant channels distributed in the circumferential direction, at least one flushing medium channel and a sensor leadthrough opening.
- the sensor passage recess extends at least partially parallel to the at least one flushing medium channel.
- the probe housing also has a sensor receptacle into which the sensor feedthrough opening opens, with the sensor receptacle having a measurement section opening.
- the sensor receptacle has a flushing medium outlet line with a flushing medium outlet, which is connected to the at least one flushing medium channel characterized in that the flushing medium outlet line has a tapered cross section to form a nozzle shape.
- the measuring section opening connects the sensor mount with the environment.
- the sensor mount is used to hold a sensor head of a sensor, with a measurement output of the sensor head being able to be arranged in the direction of the measuring section opening, so that the measurement can take place through the measuring section opening of the sensor mount.
- the sensor feedthrough recess can be used, for example, for inserting the sen sorkopfes into the sensor receptacle, it also being possible for signal lines of the sen sor to be routed through the sensor feedthrough recess.
- the flushing medium serves to protect the measuring section opening or a sensor head used in the sensor mount.
- the flushing medium outlet line By configuring the flushing medium outlet line with a tapering cross section to form a nozzle shape, the flow of the flushing medium can be accelerated. As a result, particularly effective protection against the flow of hot gas and particularly good heat dissipation through the flushing medium can be achieved. Due to the increased Ge speed of the flushing medium, the flushing performance is further improved and the tendency to soiling is reduced because the particles are deflected earlier by the flow of the flushing medium.
- the probe housing according to the invention thus provides that the at least one flushing medium channel and the sensor feedthrough recess are arranged inside the probe housing, with the coolant channels being arranged further outside and surrounding the at least one flushing medium channel and the sensor feedthrough recess. Due to the arrangement of the sensor guide recess and the at least one flushing medium channel offset from the central axis, they can be arranged in the probe housing in an advantageous manner and in a space-saving manner. Provision is preferably made for the coolant channels to be arranged evenly distributed in the circumferential direction. In this way, a particularly advantageous and uniform cooling of the probe housing is possible. In principle, it can be provided that some of the coolant channels are used for supplying the coolant and the remaining coolant channels are used for removing the heated coolant.
- the probe housing consists of a tubular outer body and an inner body, the inner body being surrounded by the outer body and the sensor lead-through recess and the at least one flushing medium channel being arranged in the inner body.
- the probe housing can also be a monolithic body, in which the inner and outer bodies are connected to form one component during the manufacturing process (e.g. by sintering, casting or printing).
- the tubular outer body has an oval or elliptical cross-section.
- the inner body can be adapted to the shape of the outer body.
- An offset to a central axis of the probe housing arrangement of the sensor passage recess and the at least one flushing medium channel allows the design of the probe housing with an outer body with an oval or elliptical cross-section and thus a configuration with reduced Strö flow resistance in a particularly advantageous manner.
- the cross section of the sensor feedthrough recess has a shape adapted to a sensor head and/or sensor.
- the configuration of the invention with a tubular outer body having an oval or elliptical cross section also has independent inventive cal significance and can thus also be implemented independently of the configuration of the flushing medium outlet line.
- the embodiment of the invention with a tubular outer body can be oval or elliptical Cross-section can be combined with individual, several or all of the features described above and below.
- the coolant channels are arranged on the circumference of the inner body. Provision is preferably made for the coolant channels to be formed by depressions in the inner body, with the outer body delimiting the coolant channels at least on one side. Such a construction has proven to be particularly advantageous.
- the cooling ducts can advantageously be installed in the inner body in the form of grooves, the cooling ducts then being completely closed in the circumferential direction by inserting the inner body into the outer body.
- the inner body can be made of a different material than the outer body, so that, for example, a particularly heat-resistant material can be used for the outer body.
- the coolant channels can have different cross sections.
- the cooling capacity of the individual coolant channels is adapted to the heat load on the probe housing.
- a coolant channel in a region of the probe housing that faces a hot gas flow during use can have a larger cross section than a coolant channel in a region of the probe housing that faces away from the hot gas flow during use.
- a diaphragm and/or optically transparent disk to be arranged in or on the measuring section opening, which has or have a main surface.
- the probe housing can thus be adapted to the sensor.
- the aperture and/or optically permeable pane can also serve as additional protection for a sensor head used in the sensor recording.
- the flushing medium outlet is arranged at an acute angle a to a plane in which the main surface lies.
- the flushing medium flows in one direction onto the main surface and not parallel to or away from the main surface.
- Particularly good heat dissipation can be achieved by the flow against the main surface of the pane or screen because it is ensured that the flushing medium sweeps over the main surface and thus touches it.
- the main surface can be cleaned by flushing away particles adhering to the main surface with the flushing medium.
- the angle a can be, for example, between 1.5° and 5°, preferably 2°.
- a flushing medium outlet is to be understood at an acute angle a to a plane in such a way that the angle of a center line of the section of the flushing medium outlet runs at the corresponding angle to the plane.
- the configuration of the invention with a flushing medium outlet at an acute angle a to a plane in which the main surface lies also has independent inventive significance and can thus also be implemented independently of the configuration of the flushing medium outlet line with a tapering cross section.
- the embodiment of the invention with a flushing medium outlet at an acute angle ⁇ to a plane in which the main surface lies can be combined with individual, several or all of the features described above and below.
- the flushing medium outlet line is shaped as a Laval nozzle.
- the flushing medium can be accelerated to very high speeds, which are even higher than the speed of sound.
- particularly effective protection against the flow of hot gas and particularly good heat dissipation through the flushing medium can be achieved.
- the scavenging medium outlet line or the scavenging medium outlet can in principle also be arranged parallel to a plane in which the main surface lies, so that the scavenging medium flows parallel to the main surface.
- the flushing medium outlet has a rectangular cross section with a long side and a short side and the flushing medium outlet is arranged with the long side parallel to the main surface of the measuring section.
- a flushing medium flow can be generated which is relatively wide and sweeps over a large area of the measuring section and thus flushes it as well.
- the opening plane of the measurement section opening or the main surface of the diaphragm arranged in the measurement section opening or the optically transmissive disk can be arranged orthogonally or parallel to the central axis.
- the optically transparent pane can have an optical element.
- the optical element can, for example, have a collecting property for optical radiation.
- the optical element can be a lens.
- the optical element can, for example, be integrated into the optically transparent pane or be provided in addition to it.
- an optically transparent pane is understood to be a pane which, when optical sensors are used, lets through sufficient optical radiation for the sensor and in a wavelength range in which the optical sensor works.
- the optically transparent pane can let through at least 50% of the radiation in the corresponding wavelength range.
- the flushing medium outlet line crosses the measuring section opening, it being possible to generate a blocking air flow in the measuring section opening.
- a blocking air flow is generated by means of the flushing medium, which causes effective protection of a sensor head placed in the sensor receptacle against hot gas flow.
- the sealing air flow can be generated particularly advantageously by accelerating the flow of the flushing medium due to the tapering cross section of the flushing medium outlet line.
- An embodiment of the invention in which the scavenging medium outlet line crosses the measuring section opening, with a blocking air flow being able to be generated in the measuring section opening, also has independent inventive significance and can therefore also be implemented with a tapering cross section independently of the configuration of the scavenging medium outlet line.
- the embodiment of the invention in which the flushing medium outlet line crosses the measuring section opening can be combined with individual, several or all of the features described above and below.
- the invention also provides a probe device with a sensor having a sensor head and a probe housing according to the invention, the sensor head being arranged in the sensor receptacle and a measuring output of the sensor head being arranged in the direction of the measuring section opening.
- the probe device according to the invention it can be provided that measuring lines leading to the sensor head are arranged to run through the sensor feedthrough recess.
