Definitions
- the invention relates to a plate heat exchanger, comprising a sensor device and a
- Measuring medium which is influenced by the temperature of at least one of the fluids and is connected to a control and / or regulating device, wherein the measuring space is defined in part by at least one of the heat exchange fluids.
- a control and / or regulating device wherein the measuring space is defined in part by at least one of the heat exchange fluids.
- an optimal control of the plate heat exchanger is realized.
- various technological and technical solutions are given, which perform a drinking water heating via a heat exchanger by means of the control of the flow temperature.
- this is a thermal solution that takes place outside of the plate heat exchanger, and thus a corresponding large inertia of the circuit is present.
- proportional regulators which carry out an opening or closing of a valve area via a membrane, which is acted upon by the cold water, and via a corresponding plunger present therewith.
- the high economic mechanical effort not the direct influence of temperature, but only a ratio of cold water to the heating medium and no holding function to be regarded as disadvantages. It is precisely these disadvantages of the prior art that presuppose the aim of the inventive solution that a technical design should be achieved here which eliminates the essential disadvantage of the prior art with little technical effort.
- EP-B-608195 discloses a plate heat exchanger having a sensor device comprising a temperature sensor with an elongate shape.
- the temperature sensor extends in one of the through-hole channels of the plate heat exchanger, which communicates with some of the heat transfer passages of the plate stack.
- the temperature sensor is connected via a so-called capillary tube, which has a valve for controlling a flow z.
- B. has district heating water through the plate heat exchanger.
- WO 97/00415 discloses a plate heat exchanger used as an oil cooler.
- the plate heat exchanger comprises a valve which is controlled by a sensor of a different type, namely a temperature-sensitive spring, which is fixed in a housing to a through-hole channel of the plate heat exchanger.
- the valve opens and closes a secondary channel in the plate heat exchanger.
- DK-U-9600205 discloses a plate heat exchanger provided with a space located on the outside of the
- Plate heat exchanger is located and connected to a Exterior surface of the plate heat exchanger extends. In the room an elongated temperature sensor is provided. The space is connected to passages for one of the fluids in the plate heat exchanger. The space is provided near an inlet or outlet port of the plate heat exchanger. The temperature sensor is arranged to cooperate with the equipment to control a flow of one of the fluids through the plate heat exchanger.
- Each of these documents thus proposes to provide a separate sensor outside the plate heat exchanger or in any of the through-hole channels of the plate heat exchanger.
- the provision of such a separate sensor is difficult from the viewpoint of manufacture.
- a sensor in any one of the through-hole channels results in increased flow resistance, not only because of the sensor itself, but also because of the components needed to mount the sensor in the through-hole channel.
- the known arrangements also have the further disadvantage that the time constant is long, that is, it takes a relatively long time before a temperature change of one or both fluids to a sufficient influence on this medium and thus z. B. leads to a desired change in the valve position.
- EP 1 362 214 is known, wherein a plate heat exchanger is designed, which has a has closed space for a measuring medium.
- the disadvantage of this technical solution is that in addition to the existing heat transfer plates an extra space closed plate for the containment of the medium must be integrated, which represents a considerable technical effort.
- the object of the invention is to find a plate heat exchanger, which eliminates the disadvantages of the prior art and makes no additional closed measuring space for a measuring medium as an addition to the plate heat exchanger necessary.
- a plate heat exchanger is carried out according to the main claim 1 and its dependent claims.
- a plate heat exchanger of known type wherein a stack of heat transfer plates is formed with the passages for the heat exchange fluid.
- the heat transfer plates of the plate heat exchanger are closed by boundary plates.
- the limiting plate communicating with the measuring space has stationary opening, via which the measuring space with the measuring medium can be coupled to a sensor device, are detected with the physical changes in the measuring space.
- measuring media are used which react to a temperature change of a heat exchanger fluid and thus forward a corresponding actuating signal to a sensor device.
- measurement media are included, which cause a corresponding pressure change due to temperature change and thus act on the connected sensor device.
- the measuring space between the outer boundary plate and the associated heat transfer plate of the stack is at least partially defined by means of the outer heat transfer plate and the boundary plate.
- An opening, which is in communication with the measuring space, is designed as a flow opening, through which the measuring medium can reach the sensor device, furthermore the measuring space is coupled in conjunction with the opening with a capillary channel.
- the opening is defined such that a recess widening the measuring space is formed in the limiting plate, which is at least partially filled with the measuring medium.
- the size of the widening recess of the opening is crucial, so that the best possible temperature influence of the Heat exchange fluids to the measuring medium, which is given in the opening in the form of the widening recess, is ensured.
- various expanding recesses are conceivable, which may have all existing surface shapes.
- the opening as a recess widening the measuring space is necessary in order thus to realize an optimum transition of the temperature detection of the heat exchanger fluid via the measuring medium to the sensor device via the capillary channel.
- the opening is advantageously arranged between the connections for the heat exchanger fluids in the boundary plate.
- the opening in connection with the measuring space should have a greater longitudinal extent than transverse extent in its areal shape.
- the opening in the form of a slot is at least over one third of the length of the boundary plate.
- the slot as a shape of the widening recess of the opening is designed so that an acute angle is formed in the direction of the boundary plate between the slot and the plate channels. It is also conceivable that the opening in the form of a slot or other planar widening recess at any point of the boundary plate is present.
- the invention is embodied such that the opening on the outer heat transfer plate is arranged opposite to the plate channels formed by surface structuring, wherein the arrangement of the opening is designed so that it is opposite to the plate channel region in which the plate channels converge. It is important that the opening extends at least partially substantially transversely to the plate channels.
- connection of the capillary channel with a respective access to the opening of the measuring chamber should be carried out so that it is aligned opposite in the plate channel area.
- To the opening on the limiting plate on the outside arranged cover plate is assigned.
- the cover plate serves to close the opening as a widening recess of the measuring space between the boundary plate and the associated heat transfer plate, thereby ensuring access for the capillary channel to the sensor device.
- a limiting plate 1 of a given plate heat exchanger 9 is provided with an integrated plate stack of heat transfer plates of known design.
- the heat transfer plates are designed with corresponding plate channels 4 so that these plate channels 4 are arranged in waveform and additionally have a tip plate channels 11. These individual heat transfer plates are arranged one above the other as a stack of plates.
- the plate heat exchanger 9 is kontruiert with a running above and below boundary plate 1.
- the boundary plates 1 are each executed with the above and below
- Heat transfer plates are the corresponding ones
- Heat exchange fluids are given as exchange medium.
- the plate heat exchanger 9, as described on the side, has been changed according to the invention so that a measuring space between the outer boundary plate 1 and the associated heat transfer plate of Stack is present and the boundary plate 1 has an opening 3 in communication with the measuring space.
- This opening 3 as a measuring space widening recess in the boundary plate 1 is realized as a slot 12.
- a measuring medium 10 is coupled to a sensor device, whereby the physical changes in the measuring space are detected.
- the measuring space is at least partially defined by means of the outer heat transfer plate and the boundary plate 1.
- the measuring space and the associated opening 3 in the form of a slot 12 defined therefrom are connected via an access 6 to a capillary channel 5.
- the opening 3 of the measuring chamber is designed as a flow opening, whereby the measuring medium 10 can reach the sensor device.
- the opening 3 is designed as a recess widening the measuring space in the limiting plate 1 in such a way that it is at least partially filled with the measuring medium 10.
- the opening 3 is designed as a slot 12.
- the slot 12 is given so that it has a greater longitudinal extent than transverse extent.
- the embodiment now shows a slot 12 between the terminals 2 and 2 ⁇ , which is arranged centrally.
- the length of the slot 12 is designed so that it comprises about one third of the total length of the plate heat exchanger 9.
- the arrangement of the slot 12 is also conceivable over the entire length or at other locations in the middle or on the other side of the boundary plate 1.
- the slot 12 is arranged at the outlet of the plate heat exchanger 9 from a metrological point of view.
- the slot 12 in the boundary plate 1 also has an access 6 for the connection of a capillary channel 5.
- a cavity is formed above the slot 12 in the plane of the slot 12 of the opening 3 and a connection with the underlying plate channels 4 of the heat transfer plate based on the cavity of the slot 12 and the waveform of the plate channel 4.
- a measuring medium 10 is input in the form of a capillary.
- the measuring medium 10 can also be acted upon by other temperature-dependent media. Due to the direct contact of the measuring medium 10 in the cavity between the plate channels 4 of the heat transfer plate and the slot 12 is on the access 6 and in connection a capillary channel 5 a direct departure given change in the measuring medium 10.
- Plate channels 4 converge. With a view of the boundary plate 1 between the slot 12 and the plate channels 4 creates an acute angle.
- the slot 12 of the limiting plate 1 is on the
- a separate cover plate 7 is executed.
- This cover plate 7 is air-tight and liquid-tight over the size of the slot 12 applied to the limiting plate 1 for closing the slot 12.
- the access 6 for the capillary channel 5 is performed by the cover plate 7, thus ensuring the flow opening for the measuring medium 10 from the measuring space to the sensor device.
- this arrangement of the cover plate 7 can be seen in that the slot 12 in the boundary plate 1 with the contained measuring medium 10 is embodied in the cavity between the plate channels 4 and the slot 12. In this case, the cover plate 7 is longer in size than the existing slot 12 in the boundary plate. 1 Based on this inventive arrangement of the described embodiment of Figures 1,
- the advantage of the inventive solution is given by the fact that no separate measuring space is required as installation or cultivation for the admission of a measuring medium 10. This eliminates a major drawback of the prior art.
- Essential to the invention is in the technical solution that a given plate heat exchanger 9 of known type is changed so that in its construction a measuring space in conjunction with an opening
- Measuring medium 10 is integrated. Via the access 6 and the capillary channel 5 control and control equipment for the further application of the plate heat exchanger 9 can now be connected. As already described, therefore, no additional space in the form of a plate or plate mounting as a measuring space for the measuring medium 10 must be integrated, which is a high technical effort and represents the disadvantage of the known technical solution.
